METHODS: This study included 70,486 participants in the Japan Public Health Center-based Prospective Study at the age of 45-74 years in 1995-1999. A validated food frequency questionnaire was used to assess the consumption of sugary drinks. We estimated the risk of total and cause-specific mortality associated with sugary drink consumption using Cox proportional hazards regression model. RESULTS: Mean follow-up was 17.1 years, during which 11,811 deaths were documented. Sugary drink consumption was associated with higher total mortality, with multivariate HR of 1.06 (95% CI 1.00-1.13) for quintile 3, 1.07 (95% CI 1.01-1.13) for quintile 4, and 1.15 (95% CI 1.09-1.22) for quintile 5, compared with quintile 1 (P < 0.001 for trend). Additionally, positive associations with cause-specific mortality were observed, including death from circulatory system diseases (quintile 5 vs quintile 1; HR, 1.23; 95% CI 1.09-1.38) and heart disease (quintile 5 vs quintile 1; HR, 1.35; 95% CI 1.14-1.60). CONCLUSION: In this large Japanese prospective study, sugary drink consumption was associated with all-cause and cause-specific mortality., Jul. 2021, 148, 106561, 106561, Scientific journal, True, 10.1016/j.ypmed.2021.106561

• Refereed, Cancer Epidemiol Biomarkers Prev., Sugary drink consumption and subsequent colorectal cancer risk: the Japan Public Health Center-based Prospective Cohort Study, Leung CY; Abe SK; Sawada N; Ishihara J; Takachi R; Yamaji T; Iwasaki M; Hashizume M; Inoue M; Tsugane S, BACKGROUND: Most studies examining the associations of sugary drink consumption on colorectal cancer risk have been conducted in Western populations. METHODS: This study consisted of 74,070 participants in the Japan Public Health Center-based Prospective Study who completed a food frequency questionnaire (1995-1999). The participants were followed until December 2013 to investigate the associations between sugary drink consumption and colorectal cancer risk using Cox proportional hazards regression models. RESULTS: Among the 74,070 participants, mean age was 56.5 years at baseline, with a mean body mass index (BMI) of 23.5 and a mean daily consumption of 286 mL/day for men and 145 mL/day for women. During a follow-up of 15 years, 1,648 colorectal cancer cases were identified. No overall greater risk of colorectal cancer was observed among men [multivariable HR = 0.84; 95% confidence of interval (CI), 0.70-1.02; ≥254 mL/day vs. nonconsumers] and women (HR = 1.20; 95% CI, 0.96-1.50, ≥134 mL/day vs. nonconsumers). Sugary drink consumption was associated with colon cancer among women (HR = 1.36; 95% CI, 1.03-1.78, ≥134 mL/day vs. nonconsumers). HRs for proximal colon cancer among women who consumed sugary drinks, as compared with nonconsumers, were 1.47 (95% CI, 1.03-2.10) for sugary drink consumption less than 134 mL/day, and 1.45 (95% CI, 1.01-2.09) for at least 134 mL/day. CONCLUSIONS: In this large prospective cohort of Japanese with a moderate sugary drink consumption level and low prevalence of obesity, we observed a 36% increased risk of colon cancer in women. IMPACT: Our findings highlight the importance of subsite- and sex-specific investigation., Apr. 2021, 30, 4, 782, 8, Scientific journal, True, 10.1158/1055-9965.EPI-20-1364

However, the correlation based on a large sample of the test meal with the evidence of many nutrients is yet to be determined. We conducted this study to assess the correlation and difference between the food-photographic record and weighed results for 44 nutrients based on a larger number of test meals than those in previous studies. Methods We assessed the nutrients of test meals using a food-photographic record and direct weighing and compared the results of the two methods. Twenty participants prepared a total of 1163 test meals. Each participant cooked 28–29 different kinds of dishes. Five participants cooked the same dish with their own recipes. For the most commonly consumed 41 dishes, 20 participants served a meal with their usual portion size. For the remaining 73 dishes, five participants served a meal with their usual portion size. An independent researcher weighed each ingredient and calculated the nutrients of the test meals. The participants took photographs of the test meals using a digital camera. Two independent, trained analysts measured the longitudinal and transverse diameters of the food area on the photographs of the test meals, compared the portion size with the reference photographs, and calculated the nutrients based on a database that contained reference photographs. Results Rank correlation coefficients between estimates from the food-photographic record of each test meal and weighed results were high for portion size (r = 0.93), energy (r = 0.93), protein (r = 0.90), fat (r = 0.92), and carbohydrate (r = 0.94), and those for the 44 nutrients ranged from 0.78 to 0.94. We found high reproducibility between the two analysts for all the nutrients (r > 0.90). Conclusions We found a high correlation and small difference between the food-photographic record method and weighed results of a large number of nutrients in many test meals., Dec. 2020, 19, 1, 104, Scientific journal, 10.1186/s12937-020-00615-y

• Refereed, PLOS ONE, Public Library of Science (PLoS), Association between meat intake and mortality due to all-cause and major causes of death in a Japanese population, Eiko Saito; Xiaohe Tang; Sarah Krull Abe; Norie Sawada; Junko Ishihara; Ribeka Takachi; Hiroyasu Iso; Taichi Shimazu; Taiki Yamaji; Motoki Iwasaki; Manami Inoue; Shoichiro Tsugane, We examined the association between meat intake and mortality due to all-cause and major causes of death using a population-based cohort study in Japan. 87,507 Japanese aged between 45 and 74 years old at 5-year follow-up study were followed for 14.0 years on average. Associations between meat intake and mortality risk were assessed using a Cox proportional hazards model. A heavy intake of total meat was associated with a higher risk of all-cause mortality relative to the lowest quartile intake in men (Q4: HR,1.18; 95%CIs, 1.06–1.31). A higher intake of total meat was associated with a lower risk of stroke mortality in women (Q2: HR, 0.70; 95%CIs, 0.51–0.94, Q3: HR, 0.68; 95%CIs, 0.50–0.95, Q4: HR, 0.66; 95%CIs, 0.44–0.99). A heavy intake of red meat was also associated with all-cause mortality (Q4: HR, 1.13; 95%CIs, 1.02–1.26) and heart disease mortality (Q4: HR, 1.51; 95%CIs, 1.11–2.06) in men but not in women. Heavy intake of chicken was inversely associated with cancer mortality in men. Heavy intakes of total and red meat were associated with an increase in all-cause and heart disease mortality in men, while total meat intake was associated with a lower risk of stroke mortality in women. , Dec. 2020, 15, 12, e0244007, e0244007, Scientific journal, 10.1371/journal.pone.0244007

• Refereed, Cancer Medicine, Wiley, Fermented and nonfermented soy foods and the risk of breast cancer in a Japanese population‐based cohort study, Ritsuko Shirabe; Eiko Saito; Norie Sawada; Junko Ishihara; Ribeka Takachi; Sarah Krull Abe; Taichi Shimazu; Taiki Yamaji; Atsushi Goto; Motoki Iwasaki; Manami Inoue; Shoichiro Tsugane, BACKGROUND: Although preclinical studies suggest that fermented soy foods may have a protective effect against breast cancer, no prospective cohort studies have examined this association. OBJECTIVE: Our study examined the association between fermented and nonfermented soy food intake and breast cancer risk using a population-based prospective cohort study in Japan. METHODS: We included a total of 47,614 women aged 45-74 years in an analysis of the Japan Public Health Center-based Prospective Study (JPHC Study). A validated food frequency questionnaire (FFQ) was used for the assessment of dietary intake. Breast cancer incidence was analyzed by multivariate Cox proportional hazards regression models. RESULTS: During an average of 15.5 years of follow-up, 825 breast cancer cases were newly identified. We found no association of intake of soy foods with breast cancer risk, regardless of fermentation, with multivariate hazard ratios (HRs) and 95% confidence intervals (CIs) for the highest quartiles of fermented and nonfermented soy food intake of 0.94 (0.67, 1.32) and 1.15 (0.85, 1.57) compared with the lowest quartile (p for trend = 0.305 and 0.393). Unlike nonfermented soy, higher intake of fermented soy foods was associated with a significant decrease in the risk of nonlocalized breast cancer. The HR and 95% CI in the highest compared to lowest intake category of fermented soy foods was 0.53 (0.28, 0.99) versus nonfermented soy foods 0.85 (0.51, 1.42) (p for trend = 0.026 and 0.797). CONCLUSIONS: Our analyses showed that fermented soy foods had no association with overall breast cancer but may be associated with decreased risk of nonlocalized breast cancer., Dec. 2020, 10, 2, 757, 771, Scientific journal, True, 10.1002/cam4.3677

We aimed to determine demographic and lifestyle variables associated with vitamin D decline by sufficiently controlling for seasonal effects of vitamin D uptake in a middle-aged to elderly population. Using a longitudinal study design within the larger framework of the Murakami Cohort Study, we examined 1044 individuals aged between 40 and 74 years, who provided blood samples at baseline and at 5-year follow-up, the latter of which were taken on a date near the baseline examination (±14 d). Blood 25-hydroxyvitamin D (25(OH)D) concentrations were determined with the Liaison^® 25OH Vitamin D Total Assay. A self-administered questionnaire collected demographic, body size and lifestyle information. Vitamin D decline was defined as the lowest tertile of 5-year changes in blood 25(OH)D (Δ25(OH)D) concentration (<6·7 nmol/l). Proportions of those with vitamin D decline were 182/438 (41·6 %) in men and 166/606 (27·4 %) in women (P < 0·0001). In men, risk of vitamin D decline was significantly lower in those with an outdoor occupation (P = 0·0099) and those with the highest quartile of metabolic equivalent score (OR 0·34; 95 % CI 0·14, 0·83), and higher in those with ‘university or higher’ levels of education (OR 2·92; 95 % CI 1·04, 8·19). In women, risk of vitamin D decline tended to be lower with higher levels of vitamin D intake (P_{for trend} = 0·0651) and green tea consumption (P_{for trend} = 0·0025). Predictors of vitamin D decline differ by sex, suggesting that a sex-dependent intervention may help to maintain long-term vitamin D levels., 14 Oct. 2020, 124, 7, 729, 735, Scientific journal, True, 10.1017/s0007114520001580

This study aimed to investigate the short- and long-term effects of monitoring salt concentration in homemade dishes on reducing salt intake in a Japanese population. A double-blind randomized controlled trial using a 2 × 2 factorial design with two interventions was conducted in 195 participants; they were assigned to both interventions for a group monitoring salt concentration in soups (control: no monitoring) and a group using low-sodium seasoning (control: regular seasoning). We evaluated 24-hour urinary sodium excretions at baseline and after a three-month intervention for the changes as major outcomes, at six- and twelve-months after baseline as long-term follow-up surveys. Urinary sodium excretion decreased in both intervention and control groups after the intervention. However, differences in the change for both monitoring and low-sodium seasoning interventions were statistically non-significant (p = 0.29 and 0.52, respectively). Urinary sodium excretion returned to the baseline level after twelve-months for all groups. Monitoring of salt concentration is ineffective in reducing salt intake for short- and long-term among the people studied in this cohort., Oct. 2020, 12, 10, 3034, 3034, Scientific journal, 10.3390/nu12103034

METHODS: 75,089 Participants of the Japan Public Health Center-based Prospective Study (JPHC Study) were followed from the time of the 5-year follow-up questionnaire until the end of 2012-2013. Subjects with available data on hepatitis B virus (HBV) and hepatitis C virus (HCV) infection status from blood samples (n = 14,016) and those who were anti-HCV antibody (anti-HCV) or hepatitis B virus antigen (HBsAg) positive (n = 1033) were also analyzed separately. Cox proportional hazard models were employed to calculate hazard ratios (HRs) and 95% confidence intervals (95% CIs). RESULTS: During 1,145,453 person-years, 534 newly diagnosed cases of liver cancer were identified in the JPHC Study. For miso intake among men, the multivariate-adjusted highest versus lowest quartile HR was 0.65 (95% CI, 0.48-0.89); p for trend = 0.006. Results were similar in those who were anti-HCV or HBsAg positive, 0.24 (0.08-0.70); p for trend = 0.004 highest versus lowest tertile. For the sub-analysis among only participants with known hepatitis infection status and HCV and HBsAg adjustment, a similar association was observed. In the multivariate complete cohort analysis, among women, the highest intake of fried tofu was inversely associated with the risk of liver cancer, HR = 0.45 (0.26-0.80); p for trend = 0.014. CONCLUSIONS: We observed no association between total soy intake, fermented and unfermented, and risk of liver cancer, and only an inverse association between miso intake and liver cancer among men., 27 Jul. 2020, 60, 3, 1389, 1401, Scientific journal, True, 10.1007/s00394-020-02335-9

• Refereed, Cancer Epidemiology Biomarkers & Prevention, American Association for Cancer Research (AACR), Soy Food Intake and Pancreatic Cancer Risk: The Japan Public Health Center–based Prospective Study, Yoko Yamagiwa; Norie Sawada; Taichi Shimazu; Taiki Yamaji; Atsushi Goto; Ribeka Takachi; Junko Ishihara; Motoki Iwasaki; Manami Inoue; Shoichiro Tsugane, BACKGROUND: Although the poor prognosis and increasing incidence of pancreatic cancer highlight the need for prevention strategies, few lifestyle risk factors for pancreatic cancer have yet been identified. Soybeans contain various bioactive compounds. However, the association between soy food intake and pancreatic cancer risk remains unknown. METHODS: The Japan Public Health Center-based Prospective Study is a cohort study conducted in a general Japanese population. To determine the association of soy food intake and pancreatic cancer incidence, we analyzed 90,185 participants who responded to a questionnaire on medical history and lifestyle factors, including dietary factors based on a food frequency questionnaire in 1995-1998, using Cox proportional hazards models. RESULTS: During a median follow-up of 16.9 years, 577 cases of pancreatic cancer were identified. In the multivariate-adjusted model, total soy food intake was statistically significantly associated with an increased risk of pancreatic cancer [HR for the highest vs. lowest intake quartile: 1.48; 95% confidence interval (CI), 1.15-1.92; Ptrend = 0.007]. Among soy foods, nonfermented soy food intake showed a statistically significant positive association with pancreatic cancer (HR, 1.41; 95% CI, 1.09-1.81; Ptrend = 0.008), whereas fermented soy food intake showed no association (HR, 0.96; 95% CI, 0.73-1.26; Ptrend = 0.982). CONCLUSIONS: Higher intake of soy foods, particularly nonfermented soy foods, might increase pancreatic cancer risk. IMPACT: This study is the first to report an association between the intake of various soy foods and pancreatic cancer risk. Further studies are required to confirm our findings., Jun. 2020, 29, 6, 1214, 1221, Scientific journal, True, 10.1158/1055-9965.epi-19-1254

This study aimed to determine whether intakes of these nutrients predict incident osteoporotic fractures. We adopted a cohort study design with a 5-year follow-up. Subjects were 12 794 community-dwelling individuals (6301 men and 6493 women) aged 40–74 years. Dietary intakes of Ca, vitamin D and vitamin K were assessed with a validated FFQ. Covariates were demographic and lifestyle factors. All incident cases of major osteoporotic limb fractures, including those of the distal forearm, neck of humerus, neck or trochanter of femur and lumbar or thoracic spine were collected. Hazard ratios (HR) for energy-adjusted Ca, vitamin D and vitamin K were calculated with the residual method. Mean age was 58·8 (sd 9·3) years. Lower energy-adjusted intakes of Ca and vitamin K in women were associated with higher adjusted HR of total fractures (P_{for trend} = 0·005 and 0·08, respectively). When vertebral fracture was the outcome, P_{for trend} values for Ca and vitamin K were 0·03 and 0·006, respectively, and HR of the lowest and highest (reference) intake groups were 2·03 (95 % CI 1·08, 3·82) and 2·26 (95 % CI 1·19, 4·26), respectively. In men, there were null associations between incident fractures and each of the three nutrient intakes. Lower intakes of dietary Ca and vitamin K were independent lifestyle-related risk factors for osteoporotic fracture in women but not men. These associations were robust for vertebral fractures, but not for limb fractures., 07 May 2020, 1, 10, Scientific journal, 10.1017/s0007114520001567

OBJECTIVE: To determine the associations between changes in fruit and vegetable consumption and weight change over a 5-year interval in Japanese adults. METHODS: This cohort study included 54,015 subjects (54.6% female, mean age 56.5 years) of the Japan Public Health Center-based Prospective Cohort Study who had no known history of major chronic diseases at baseline. Data on fruit and vegetable consumption were collected using a validated food frequency questionnaire. Body weight was self-reported. We used multivariable linear mixed-effects regression models to examine the associations between changes in fruit and vegetable consumption and change in body weight. RESULTS: On average, body weight decreased by 25 g [95% confidence interval (CI), 3, 47] for every 100 g/d increase in total vegetable consumption. Change in fruit consumption was nonlinearly associated with weight change. Fruit consumption was directly associated with weight change among subjects who increased consumption (70 g; 95% CI, 39, 101) but was not associated with weight change among subjects who reduced or did not change fruit consumption. These associations did not vary by sex, age, and body mass index (BMI) at baseline. The association with vegetables was restricted to yellow/red vegetables (- 74 g; 95% CI, - 129, - 18) and allium vegetables (- 129 g; 95% CI, - 231, - 28). Lower-fiber vegetables were inversely associated with weight change, whereas lower-fiber fruits or higher-energy fruits were directly associated with weight change beyond 0 g/d change in consumption. CONCLUSIONS: Change in vegetable consumption was inversely associated with weight change while fruit consumption was positively associated with weight change among subjects who increased consumption. The influence of fruits and vegetables on weight change may depend on the characteristics of the fruits and vegetables., 06 Apr. 2020, 60, 1, 217, 227, Scientific journal, True, 10.1007/s00394-020-02236-x

The population-based prospective Uonuma CKD cohort study aims to explore associations of lifestyle and other risk factors with CKD. We report here the study design and baseline profiles. METHODS: All 67,322 residents aged ≥40 years in Minamiuonuma City, Uonuma City, and Yuzawa Town, Niigata Prefecture, Japan and 11,406 participants who attended local health-check examinations were targeted for baseline questionnaire and biochemical sampling, respectively. Information was gathered from 43,217 (64.2%) questionnaires and 8,052 (70.6%) biochemical samples; 6,945 participants consented to both questionnaire and biochemical sampling at baseline, conducted between fiscal years 2012 and 2015. Participants provided information regarding sociodemographic, lifestyle, and self-reported outcomes. Urine albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR) were measured. The primary outcome is CKD based on self-report and biochemical/clinical diagnosis. RESULTS: Mean age of questionnaire respondents was 63.3 (standard deviation [SD], 12.5) years for men and 64.3 (SD, 13.3) years for women. Among participants who submitted urine samples, median ACR was 10.0 (interquartile range [IQR], 5.0-24.0) mg/g for men and 13.0 (IQR, 7.7-27.0) mg/g for women, and median eGFR was 73.6 mL/min/1.73 m2 (IQR, 63.5-84.5) for men and 73.5 mL/min/1.73 m2 (IQR, 64.4-83.5) for women. ACR 30 mg/g or more was found in 1,741 participants (21.7%) and eGFR <60 mL/min/1.73 m2 in 1,361 participants (16.9%). CONCLUSION: The Uonuma CKD cohort study was established to investigate the impact of lifestyle on CKD development and to provide data for preventing the onset and progression of CKD., 05 Apr. 2020, 30, 4, 170, 176, Scientific journal, False, 10.2188/jea.je20180220

This study aimed to assess the relationship between total physical activity and risk of CLBP and CKP from a public health perspective. METHODS: Participants were 7,565 individuals, aged 40-74 years, who did not have CLBP or CKP, and who participated in the 5-year follow-up survey. A self-administered questionnaire was used to obtain information on demographics, body size and lifestyle (including physical activity) in the baseline survey in 2011-2013, and on CLBP and CKP using Short Form 36 (SF-36) in the follow-up survey. Sitting, standing, walking and strenuous work for occupational activity were assessed for total physical activity, and walking slowly, walking quickly, light to moderate exercise and strenuous exercise were assessed for leisure-time physical activity using metabolic equivalent hours/day (METs score). RESULTS: Mean age of participants was 60.1 years (SD, 8.8). Participants with higher METs scores had a significantly higher risk of CKP (p for trend = 0.0089, OR of 4th quartile = 1.29, 95% CI: 1.04-1.59 vs. 1st quartile), but not CLBP. An intermediate leisure-time METs score was associated with a lower risk of CLBP (OR = 0.75, 95%CI: 0.61-0.92 vs. 0 METs-group). CONCLUSIONS: A high level of total physical activity may increase the risk of CKP, whereas an intermediate level of leisure-time physical activity may decrease the risk of CLBP, in middle-aged and elderly individuals. SIGNIFICANCE: Evidence on the longitudinal association between total physical activity and CLBP and CKP in middle-aged and elderly people is lacking. We conducted a cohort study to assess this association, and found that high levels of total physical activity increased risk of CKP, and intermediate levels of leisure-time physical activity decreased risk of CLBP. This suggests that the effect of physical activity on chronic pain differed by pain site., Apr. 2020, 24, 4, 863, 872, Scientific journal, True, 10.1002/ejp.1535

We evaluated whether well-done/very well-done preferences for various meat and fish items, higher intakes of meat and fish, and meat-derived and fish-derived HCA are associated with the risk of colorectal adenoma (CRA) in a Japanese-Brazilian population. We selected 302 patients with adenoma and 403 control individuals who underwent total colonoscopy between 2007 and 2013, and collected information on aspects of meat intake using a detailed questionnaire. We also estimated HCA intake of the study participants using an HCA database that matched the cooking methods of this population. Latent class analysis on the basis of response to doneness preferences for different cooking methods of commonly consumed meat and fish items identified four distinct subgroups. Compared with the subgroup characterized by a preference for rare/medium well-done cooking for most meat and fish items, the odds ratio of CRA for the well-done/very well-done preference subgroup was 1.19 (95% confidence interval: 0.51-2.75). High intake of mixed-meat dishes was suggestively associated inversely with CRA, whereas a high intake of poultry was associated positively with CRA. No clear association with intake of total or specific HCAs and no effect modification by N-acetyltransferase 2 acetylation genotype were observed. We found no statistically significant associations between meat and HCA intake and CRA. These findings do not support a positive association between meat and meat-derived HCA intake and the risk of CRA., Jan. 2020, 29, 1, 7, 14, Scientific journal, True, 10.1097/cej.0000000000000506

METHODS: A Japanese cohort comprising 3250 men and 3434 women aged 40-97 years with urine albumin-to-creatinine ratio (ACR) < 33.9 mg/mmol or estimated glomerular filtration rate ≥ 15 ml/min/1.73 m2 were assessed. We performed a cross-sectional evaluation of the association between net endogenous acid production (NEAP), estimated as dietary protein to potassium content ratio, and the presence of high normoalbuminuria (ACR: 1.13-3.38 mg/mmol) or microalbuminuria. RESULTS: Median NEAP was 43.4 (interquartile range (IQR): 34.2-53.4) mEq/day in men and 35.0 (IQR: 27.7-43.6) mEq/day in women. Median ACR was 1.11 (IQR: 0.57-2.49) mg/mmol in men and 1.47 (IQR: 0.82-2.83) mg/mmol in women. In multivariate analysis, the adjusted odds ratio of the highest versus lowest NEAP quartile for microalbuminuria was 1.47 (95% confidence interval (CI): 1.08-1.99) in men and 1.54 (95% CI: 1.11-2.14) in women. For high normoalbuminuria or microalbuminuria, the adjusted odds ratio was 1.28 (95% CI: 1.02-1.59) in men and 1.39 (95% CI: 1.11-1.74) in women. From nutrient composition analysis, subjects with the highest potassium intake, but not protein intake, had lower adjusted odds ratios for the presence of microalbuminuria than those in the lowest quartile for potassium intake. CONCLUSIONS: Higher NEAP was associated with albuminuria and its association might negatively relate to potassium intake in an adult Japanese population., Dec. 2019, 20, 1, 194, 194, Scientific journal, True, 10.1186/s12882-019-1352-8

Data were collected from January 1, 1995, through December 31, 1999, with follow-up completed December 31, 2016, during which 12 381 total deaths were documented. Dietary intake information was collected through a validated food frequency questionnaire and used to estimate protein intake in all participants. Participants were grouped into quintile categories based on their protein intake, expressed as a percentage of total energy. Data were analyzed from July 18, 2017, through April 10, 2019.MAIN OUTCOMES AND MEASURES Hazard ratios (HRs) and 95% CIs for all-cause and cause-specific mortality were estimated using Cox proportional hazards regression models with adjustment for potential confounding factors.RESULTS Among the 70 696 participants, 32 201 (45.5%) were men (mean [SD] age, 55.6 [7.6] years) and 38 495 (54.5%) were women (mean [SD] age, 55.8 [7.7] years). Intake of animal protein showed no clear association with total or cause-specific mortality. In contrast, intake of plant protein was associated with lower total mortality, with multivariable-adjusted HRs of 0.89 (95% CI, 0.83-0.95) for quintile 2; 0.88 (95% CI, 0.82-0.95) for quintile 3; 0.84 (95% CI, 0.77-0.92) for quintile 4; and 0.87 (95% CI, 0.78-0.96) for quintile 5, with quintile 1 as the reference category (P = .01 for trend). For cause-specific mortality, this association with plant protein intake was evident for cardiovascular disease (CVD)-related mortality (HRs, 0.84 [95% CI, 0.73-0.96] to 0.70 [95% CI, 0.59-0.83]; P = .002 for trend). Isocaloric substitution of 3% energy from plant protein for red meat protein was associated with lower total (HR, 0.66; 95% CI, 0.55-0.80), cancer-related (HR, 0.61; 95% CI, 0.45-0.82), and CVD-related (HR, 0.58; 95% CI, 0.39-0.86) mortality; substitution for processed meat protein was associated with lower total (HR, 0.54; 95% CI, 0.38-0.75) and cancer-related (HR, 0.50; 95% CI, 0.30-0.85) mortality.CONCLUSIONS AND RELEVANCE In this large prospective study, higher plant protein intake was associated with lower total and CVD-related mortality. Although animal protein intake was not associated with mortality outcomes, replacement of red meat protein or processed meat protein with plant protein was associated with lower total, cancer-related, and CVD-related mortality., 01 Nov. 2019, 179, 11, 1509, 1509, Scientific journal, 10.1001/jamainternmed.2019.2806

During 1 325 853 person-years of follow-up, 2612 CRC cases were identified. The association of cruciferous vegetable intake with CRC risk was assessed using a Cox proportional hazard regression model to compute hazard ratios (HRs) and 95% confidence intervals (CIs), adjusted for potential confounders. No significant association was observed between the highest cruciferous vegetable intake quartile (compared with the lowest) and CRC risk in men (multivariate HRs: 1.08; 95% CI: 0.91, 1.29) and women (multivariate HRs: 0.99; 95% CI: 0.80, 1.22) and its subsites. Women showed a marginal negative association between cruciferous vegetable intake and the risk of colon cancer (CC) after excluding participants who developed CC in the first 3 years of follow-up (P for trend = 0.08); a positive association was found with proximal CC in men. Cruciferous vegetable intake does not have a significant association with CRC risk in the Japanese general population., Sep. 2019, 28, 5, 420, 427, Scientific journal, True, 10.1097/cej.0000000000000491

Although fruits and vegetables are abundant in antioxidants and anti-inflammatory constituents, the reported associations between fruit and vegetable intake and pancreatic cancer risk have been inconsistent. Here, we investigated the association between fruit and vegetable intake and pancreatic cancer risk as part of the Japan Public Health Center-based Prospective Study. The analysis included 90,185 participants who responded to a medical and lifestyle questionnaire during 1995-1998. Associations between fruit and vegetable intake and pancreatic cancer risk were evaluated with Cox proportional hazards models. Additional analyses were stratified by smoking status and body mass index. During follow-up (median duration, 16.9 years), 577 participants were diagnosed with pancreatic cancer. In multivariate-adjusted models, pancreatic cancer risk was inversely associated with total fruit intake (highest vs. lowest intake quartile; hazard ratio [HR]: 0.74, 95% confidence interval [CI]: 0.57-0.95, p-trend: 0.116) and positively associated with total vegetable intake (HR: 1.30, 95% CI: 1.01-1.66, p-trend: 0.151). For total fruit intake, the inverse association with pancreatic cancer risk was more apparent in never smokers (HR: 0.67, 95% CI: 0.47-0.97, p-trend: 0.034). For total vegetable intake, the positive association was statistically significant in ever smokers (HR: 1.49, 95% CI: 1.01-2.19, p-trend: 0.043) and statistically nonsignificant in never smokers. In summary, total fruit intake and total vegetable intake had inverse and positive associations, respectively, with pancreatic cancer risk. Vegetable intake may correlate with increased risk partly because of the influence of smoking on vegetable intake., 15 Apr. 2019, 144, 8, 1858, 1866, Scientific journal, True, 10.1002/ijc.31894

However, at present, no large cohort studies have investigated the effect of cruciferous vegetable on mortality. We aimed to examine the association between cruciferous vegetable intake and all-cause mortality, namely cancer, heart disease, cerebrovascular disease, and injuries, in a large cohort study conducted between 1990 and 1993, in Japan. METHODS: The analysis included 88,184 participants (age: 45-74 years) with no history of cancer, myocardial infarction, and stroke. Participants were tracked for a median of 16.9 years, during which 15,349 deaths were occurred. The association between cruciferous vegetable intake and risk of all-cause and cause-specific mortality was determined by Cox proportional hazard regression analysis to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs), after adjustment for potential confounding factors. RESULTS: An inverse association was found between cruciferous vegetable intake and total mortality in both gender. HRs (95% CI) for all-cause mortality in the highest compared to the lowest quintile were 0.86 (0.80, 0.93) for men (P = 0.0002 for trend) and 0.89 (0.81, 0.98) for women (P = 0.03 for trend). Cruciferous vegetable intake was associated with lower cancer mortality in men, as well as with heart disease-, cerebrovascular disease-, and injury-related mortality in women. CONCLUSIONS: This prospective study suggests that a higher cruciferous vegetables intake is associated with reduced risk of all-cause mortality., Apr. 2019, 38, 2, 631, 643, Scientific journal, True, 10.1016/j.clnu.2018.04.012

In subsamples of the JPHC study (Cohorts I and II in multiple areas), we computed Spearman’s correlations of FFQ results with urine sugar concentrations and dietary records (DR) for validity; we evaluated correlations between two FFQs for reproducibility. During 1994–1998, participants (Cohort I: n = 27 [men], n = 45 [women]) provided two (spring and fall) 24-h urine samples and completed 7-consecutive-day DR per season (I: n = 99, n = 113; II: n = 168, n = 171) and two FFQs (147 food items) at yearly intervals (I: n = 101, n = 108; II: n = 143, n = 146). Sugar intakes from FFQ were correlated with urinary sugar (de-attenuated correlations: 0.40; 95%CI: 0.19, 0.58). After adjustment for sociodemographic and lifestyle variables, correlations between FFQ and DR for men and women were 0.57 (0.42, 0.69) and 0.41 (0.24, 0.55) (I) and 0.56 (0.44, 0.65) and 0.34 (0.20, 0.47) (II), respectively. Correlations between FFQs for men and women were 0.63 (0.49, 0.73) and 0.55 (0.41, 0.67) (I) and 0.66 (0.55, 0.74) and 0.63 (0.52, 0.72) (II).

METHODS AND STUDY DESIGN: Participants included 98 men and 142 women aged 40-74 years from the five areas included in the JPHCNEXT protocol. In November 2012, participants were recruited and asked to complete the first nutrition survey. The second nutrition survey was completed after 1 year. RESULTS: We estimated daily energy as well as 53 nutrient and 29 food group intakes using the FFQ. To assess reproducibility, we calculated Spearman correlation coefficients between both FFQs, which showed mostly intermediate-to-high values. Median (range) correlation coefficients and quartile distribution in the same and adjacent categories for energy-adjusted nutrient intakes were 0.55 (0.42-0.84) and 84.7% (76.5%-98.0%) in men and 0.54 (0.35-0.80) and 84.5% (76.1%-94.4%) in women. The respective values for energy-adjusted food group intakes in men and women were also mostly intermediate to high: 0.54 (0.39-0.79) and 83.7% (75.5%-90.8%) in men and 0.57 (0.40-0.83) and 84.5% (77.5%-93.7%) in women. CONCLUSIONS: The FFQ developed for the JPHC-NEXT study has reasonable reproducibility. Because this FFQ has also been validated in a previous study, it can be considered a useful dietary assessment tool to examine associations between dietary consumption and lifestyle-related diseases., 2019, 28, 2, 362, 370, Scientific journal, True, 10.6133/apjcn.201906_28(2).0019

This study aimed to determine the prevalence of and potential risk factors associated with chronic low back and knee pain in middle-aged and elderly Japanese. Methods: This cross-sectional study involved 14,217 community-dwelling individuals aged 40-74 years living in the Murakami area of Japan. A self-administered questionnaire was used to obtain information regarding marital status, education level, occupation, household income, and body size. Participants also reported current chronic pain, if any, by site and degree of severity, using the verbal rating scale of the Short Form 36. Results: The prevalence of moderate-very severe chronic pain was 9.7% in the low back, 6.7% in the knee, 13.9% in either the low back or knee, and 2.6% in both the low back and knee. Multivariate analysis revealed that lower education level, lower income, and manual occupation in men and older age and higher body mass index in women were significantly associated with a higher prevalence of chronic low back pain. In both sexes, older age, lower education level, and higher body mass index were significantly associated with a higher prevalence of knee pain. Regarding sex differences, adjusted ORs of chronic pain of the low back and knee for women were 0.85 (95% CI 0.75-0.97) and 1.27 (95% CI 1.09-1.49), respectively. Conclusion: Nearly 14% of middle-aged and elderly individuals had moderate-very severe chronic pain of the low back or knee, and this pain was associated with many demographic factors, including sex, age, education level, household income, occupation, and body size., Dec. 2018, 11, 3161, 3169, Scientific journal, True, 10.2147/jpr.s184746

We intended to establish a large population-based cohort study to determine environmental, lifestyle, and genetic risk factors of musculoskeletal and other age-related diseases, and to clarify the association between vitamin D status and such diseases. METHODS: We targeted 34,802 residents aged 40-74 years living in areas of northern Niigata Prefecture, including Sekikawa Village, Awashimaura Village, and Murakami City (Murakami region). The baseline questionnaire survey, conducted between 2011 and 2013, queried respondents on their lifestyle and environmental factors (predictors), and self-reported outcomes. Plasma 25-hydroxyvitamin D (25[OH]D) concentration, an indicator of vitamin D status, was determined with the Liaison® 25OH Vitamin D Total Assay. The primary outcome of this study was osteoporotic fracture; other outcomes included age-related diseases including knee osteoarthritis, perception of chronic pain, dementia, and long-term care insurance use. Mean ages of men and women were 59.2 (SD = 9.3, N = 6907) and 59.0 (SD = 9.3, N = 7457) years, respectively. From the blood samples provided by 3710 men and 4787 women, mean 25(OH)D concentrations were 56.5 (SD = 18.4) nmol/L (22.6 ng/mL) and 45.4 (SD = 16.5) nmol/L (18.2 ng/mL), respectively. DISCUSSION: Follow-up surveys are planned every 5 years for 15 years, and incident cases of our targeted diseases will be followed at hospitals and clinics in and nearby the cohort area. We anticipate that we will be able to clarify the association between vitamin D status and multiple disease outcomes in a Japanese population., Dec. 2018, 23, 1, 28, 28, Scientific journal, True, 10.1186/s12199-018-0715-2

We investigated the effect of monitoring the salt concentration of home-prepared dishes (Monitoring) on salt reduction and change in taste threshold, and the effect of the simultaneous use of low-sodium seasonings (Seasoning) to compare the effect of Monitoring with the conventional method. SUBJECTS/METHODS: We conducted a double-blind randomized controlled study using a 2 × 2 factorial design with two interventions. A total of 50 participants (40-75 years-old) were recruited among residents of Niigata Prefecture, a high sodium-consuming population in Japan, then randomly allocated to four groups. After excluding participants with incomplete urine collection, change in salt intake was evaluated using 24-hour urinary excretion as a surrogate of intake for 43 participants. Change in taste threshold was evaluated in 48 participants after excluding those with incomplete threshold measurement. RESULTS: The Monitoring intervention group showed a significant decrease in sodium intake (-777 mg/24 h), whereas the decrease in the Seasoning intervention group was not significant (-413 mg/24 h). Sodium intake did not statistically differ between the intervention and control groups (-1011 mg/24 h and -283 mg/24 h for Monitoring and Seasoning, respectively). The changes in taste threshold measurement were very small and did not markedly differ between groups. CONCLUSIONS: Monitoring the salt concentration of dishes had a potentially stronger salt-reducing effect than the use of low-sodium seasonings, a conventional method. Confirmation requires additional study with a larger sample size., Oct. 2018, 72, 10, 1413, 1420, Scientific journal, True, 10.1038/s41430-017-0053-2

Here, we examined the association between consumption of antioxidant vitamins and lung cancer risk in one of the largest prospective cohort studies in Japan. We investigated the association of dietary antioxidant vitamins intake, namely retinol, vitamin C, vitamin E, α-carotene, and β-carotene and subsequent incidence of lung cancer among 38,207 men and 41,498 women in the Japan Public Health Center-based prospective study. Cox proportional hazard regression was performed with adjustment for potential confounders and by strata of cancer subtypes and smoking status. Antioxidant and other dietary intakes were assessed using a food frequency questionnaire (FFQ). During 1,233,096 person-years of follow-up between 1995 and 2013, a total of 1,690 lung cancer cases were newly diagnosed. In a multivariate regression model, while higher retinol intake was positively associated with overall lung cancer risk in men (HR 1.26; 95% CI 1.05-1.51; ptrend  = 0.003), the estimates were more evident with small cell carcinoma (HR 1.92; 95% CI 1.13-3.24; ptrend  < 0.001). Null associations were observed for other antioxidant vitamins. Our prospective study suggests that higher consumption of retinol may be associated with an increased risk of lung cancer in men, especially with small cell carcinoma, although confirmation is required., 15 Jun. 2018, 142, 12, 2441, 2460, Scientific journal, True, 10.1002/ijc.31268

RESULTS: Three major dietary patterns were derived using exploratory factors analysis: prudent, westernized, and traditional dietary patterns. The westernized dietary pattern was associated with a higher risk of total prostate cancer (HR: 1.22; 95% CI 1.00-1.49; p trend = 0.021), localized cancer (HR: 1.24; 95% CI 0.97-1.57; p trend = 0.045), and advanced cancer (HR: 1.23; 95% CI 0.82-1.84; p trend = 0.233). The prudent dietary pattern was associated with a lower risk of total and localized prostate cancer, with respective multivariable HRs for the highest and lowest quintiles of 0.71 (95% CI 0.50-1.02; p trend = 0.037) and 0.63 (95% CI 0.38-1.03; p trend = 0.048) among subjects detected by subjective symptoms. No association was found between the traditional dietary pattern and prostate cancer risk among our subjects. CONCLUSION: Our results suggest that a western-style diet may lead to a higher risk of prostate cancer in the total population, whereas the prudent diet contributes to a lower risk among subjects detected by subjective symptoms., Jun. 2018, 29, 6, 589, 600, Scientific journal, True, 10.1007/s10552-018-1030-3

Tsugane; JPHC Study group., BACKGROUND & AIMS: A finding between dietary pattern and cancer may provide visions beyond the assessment of individual foods or nutrients. We examined the influence of dietary pattern with colorectal cancer (CRC) among a Japanese population. METHODS: A total of 93,062 subjects (43,591 men, 49,471 women) who participated in the Japan Public Health Center-based Prospective Study were followed from 1995-1998 to the end of 2012, during which 2482 cases of CRC (1514 men, 968 women) were newly identified. Dietary data was obtained from a validated food-frequency questionnaire between 1995 and 1998. RESULTS: Three dietary pattern was derived from principal components factor: prudent, westernized, and traditional pattern. After controlled for potential confounders, the prudent pattern showed a decreased association of CRC risk in men (HR for highest quintile vs lowest: 0.85; 95% CI: 0.72-1.00; P trend <0.05), slightly more strongly with distal colon cancer (P trend <0.05); but an increased risk of rectal cancer in women (P trend <0.05). The westernized pattern showed a significant positive linear trend for colon (P trend <0.05) and distal cancer (P trend <0.05) in women. There was no apparent association of traditional Japanese dietary pattern on the overall or any specific sites risk of CRC. CONCLUSIONS: A prudent dietary pattern showed an inverse association with CRC risk in men, and a westernized pattern was related with a higher risk of colon and distal cancer in women., Jun. 2018, 37, 3, 1019, 1026, Scientific journal, True, 10.1016/j.clnu.2017.04.015

  Background: Online dietary assessment tools offer advantages over printed questionnaires, such as the automatic and direct data storage of answers, and have the potential to become valuable research methods. We developed an online survey system (web-FFQ) for the existing printed FFQ used in the JPHC-NEXT protocol, the platform of a large-scale genetic cohort study. Here, we examined the validity of ranking individuals according to dietary intake using this web-FFQ and its usability compared with the printed questionnaire (print-FFQ) for combined usage.

  Methods: We included 237 men and women aged 40–74 years from five areas specified in the JPHC-NEXT protocol. From 2012 to 2013, participants were asked to provide 12-day weighed food records (12d-WFR) as the reference intake and to respond to the print- and web-FFQs. Spearman's correlation coefficients (CCs) between estimates using the web-FFQ and 12d-WFR were calculated. Cross-classification of intakes was compared with those using the print-FFQ.

  Results: Most participants (83%) answered that completing the web-FFQ was comparable to or easier than completing the printed questionnaire. The median value of CCs across energy and 53 nutrients for men and women was 0.47 (range, 0.10–0.86) and 0.46 (range, 0.16–0.69), respectively. CCs for individual nutrient intakes were closely similar to those based on the print-FFQ, irrespective of response location. Cross-classification by quintile of intake based on two FFQs was reasonably accurate for many nutrients and food groups.

  Conclusion: This online survey system is a reasonably valid measure for ranking individuals by intake for many nutrients, like the printed FFQ. Mixing of two FFQs for exposure assessments in epidemiological studies appears acceptable.

Most of the studies have focused on risks associated with specific foods and nutrients, rather than overall diet. In this study, we aimed to evaluate the association between dietary patterns and breast cancer risk in Japanese women. A total of 49 552 Japanese women were followed-up from 1995 to 1998 (5-year follow-up survey) until the end of 2012 for an average of 14·6 years. During 725 534 person-years of follow-up, 718 cases of breast cancer were identified. We identified three dietary patterns (prudent, westernised and traditional Japanese). The westernised dietary pattern was associated with a 32 % increase in breast cancer risk (hazard ratios (HR) 1·32; 95 % CI 1·03, 1·70; P_trend=0·04). In particular, subjects with extreme intake of the westernised diet (quintile (Q) Q5_5th) had an 83 % increase in risk of breast cancer in contrast to those in the lowest Q1 (HR 1·83; 95 % CI 1·25, 2·68; P_trend=0·01). In analyses stratified by menopausal status, postmenopausal subjects in the highest quintile of the westernised dietary pattern had a 29 % increased risk of breast cancer (HR 1·29; 95 % CI 0·99, 1·76; P_trend=0·04). With regard to hormone receptor status, the westernised dietary pattern was associated with an increased risk of oestrogen receptor-positive/progesterone receptor-positivetumours (HR 2·49; 95 % CI 1·40, 4·43; P_trend<0·01). The other dietary patterns were not associated with the risk of breast cancer in Japanese women. A westernised dietary pattern is associated with an increased risk of breast cancer in Japanese women., May 2016, 115, 10, 1769, 1779, Scientific journal, 10.1017/s0007114516000684

We developed a 66-item Food Frequency Questionnaire (short-FFQ) for the Japan Public Health Center-based prospective Study for the Next Generation (JPHC-NEXT) follow-up survey using major foods from the FFQ developed for the original JPHC Study. For the JPHC-NEXT baseline survey, we used a larger 172-item FFQ (long-FFQ), which was also derived from the JPHC-FFQ. We compared the validity of ranking individuals by levels of dietary consumption by these FFQs among residents of selected JPHC-NEXT study areas.
  Methods: From 2012 to 2013, 240 men and women aged 40–74 years from five areas in the JPHC-NEXT protocol were asked to respond to the long-FFQ and provide 12-day weighed food records (WFR) as reference; 228 also completed the short-FFQ. Spearman's correlation coefficients (CCs) between estimates from the FFQs and WFR were calculated and corrected for intra-individual variation of the WFR.
  Results: Median CC values for energy and 53 nutrients for the short-FFQ for men and women were 0.46 and 0.44, respectively. Respective values for the long-FFQ were 0.50 and 0.43. Compared with the long-FFQ, cross-classification into exact plus adjacent quintiles with the short-FFQ ranged from 68% to 91% in men and 58% to 85% in women.
  Conclusions: Similar to the long-FFQ, the short-FFQ provided reasonably valid measures for ranking middle-aged and elderly Japanese for many nutrients and food groups. The short-FFQ can be used in follow-up surveys in prospective cohort studies aimed at updating diet rank information., 2016, 26, 8, 420, 432, Scientific journal, 10.2188/jea.je20150064

Although this method has been validated among the rural Japanese populations for which the database was developed, the applicability of the DRcd for other populations is unclear. In this study, we have examined the applicability of DRcd among an urban population.
  Methods Subjects were selected from among patients who underwent cancer screening between 2004 and 2006 at the Research Center for Cancer Prevention and Screening, National Cancer Center, Japan. Subjects aged 40–69 years, who lived in Tokyo and the surrounding suburbs, were stratified into groups by sex and age. A total of 144 men and women agreed to participate in the study after random selection. Subjects were instructed to keep 4-day dietary records (4d-DR) of all consumed foods and beverages, including dish names, and all dishes were then coded using DRcd codes on the basis their names. The intake of 17 food groups and 40 nutrients was estimated using the dish-based nutrient composition table of the DRcd. Simultaneously, 4d-DR were used to calculate dietary intake independently, which served as a reference. We examined the applicability of the DRcd method using percentage difference and Pearson's correlation coefficients for intakes estimated using 4d-DR and the DRcd. Moreover, the results were compared to those of a previous study.
  Results A total of 88% of the recorded dishes matched the dish codes of the DRcd database by name. Pearson's correlation coefficient scores of 0.6 or higher were observed for 12 and 10 food groups, and for 34 and 27 nutrients in men and women, respectively. Notably, the intake of majority of the nutrients tended to be underestimated, a difference that was more pronounced in men. In comparison with a previous study, the percentage differences and Pearson's correlation coefficient scores for intake tended to be lower in our study.
  Conclusion As the correlation coefficients (0.6) were high for a majority of food groups and nutrients estimated by DRcd, the DRcd method may be applicable for urban populations. However, regional intake data may be necessary for the estimation of absolute value for the intake of some nutrients., 15 Sep. 2012, 59, 9, 700, 711, 10.11236/jph.59.9_700

However, few studies have examined the validity and reproducibility of dietary patterns. We assessed the reproducibility and validity of dietary patterns identified by a food frequency questionnaire (FFQ) used in the 5-year follow-up survey of the Japan Public Health Center-Based Prospective Study (JPHC Study).
  Methods: The participants were a subsample (244 men and 254 women) from the JPHC Study. Principal component analysis was used to identify dietary patterns from 28- or 14-day dietary records and 2 FFQs. To assess reproducibility and validity, we calculated Spearman correlation coefficients between dietary pattern scores derived from FFQs separated by a 1-year interval, and between dietary pattern scores derived from dietary records and those derived from a FFQ completed after the dietary records, respectively.
  Results: We identified 3 Japanese dietary patterns from the dietary records and 2 FFQs: prudent, westernized, and traditional. Regarding reproducibility, Spearman correlation coefficients between the 2 FFQs ranged from 0.55 for the westernized Japanese pattern in men and the prudent Japanese pattern in women to 0.77 for the traditional Japanese pattern in men. Regarding validity, the corresponding values between dietary records and the FFQ ranged from 0.32 for the westernized Japanese pattern in men to 0.63 for the traditional Japanese pattern in women.

They are suggested to be particularly susceptible to the adverse effects of red meat on the development of colorectal cancers, however, few prospective studies of this putative link have been conducted. We examined associations between the consumption of red and processed meat and the risk of subsite-specific colorectal cancer by gender in a large Japanese cohort. During 1995-1998, a validated food frequency questionnaire was administered to 80,658 men and women aged 45-74 years. During 758,116 person-years of follow-up until the end of 2006, 1,145 cases of colorectal cancer were identified. Higher consumption of red meat was significantly associated with a higher risk of colon cancer among women [multivariate hazard ratios (95%CIs) for the highest versus lowest quintiles (HR): 1.48 (1.01, 2.17; trend p=0.03)], as was higher consumption of total meat among men [HR=1.44 (1.06, 1.98; trend p=0.07)]. By site, these positive associations were found for the risk of proximal colon cancer among women and for distal colon cancer among men. No association was found between the consumption of processed meat and risk of either colon or rectal cancer. In conclusion, red meat intake may modestly increase the risk of colon cancer in middle-aged Japanese, although the highest quintile of red meat consumption could be considered moderate by Western standards., 2011, 20, 4, 603, 612, Scientific journal

The 138-item FFQ used in the 5-year follow-up survey for the Japan Public Health Center-based Prospective Study was initially developed for and validated in rural residents. However, the validity of estimates based on this FFQ for urban residents, whose diet and lifestyle differ from those of rural residents, has not been clarified. We examined the validity of ranking individuals according to level of dietary consumption, as estimated by this FFQ, among an urban population in Japan.
  Methods: Among 896 candidates randomly selected from examinees of cancer screening provided by the National Cancer Center, Japan, 144 participated in the study. In 2007–2008, at an average 2.7 years after cancer screening, participants were asked to respond to the questionnaire and to provide 4-day weighed diet records (4d-DRs) for use as the reference intake. Spearman correlation coefficients (CCs) between the FFQ and 4d-DR estimates were calculated, after correction for intraindividual variation of 4d-DRs.
  Results: The median (range) deattenuated CC for men and women was 0.57 (0.23 to 0.89) and 0.47 (0.08 to 0.94), respectively, across 45 nutrients and 0.51 (0.10 to 0.98) and 0.51 (−0.36 to 0.88) for 43 food groups.
  Conclusions: Although the FFQ was developed for a rural population, it provided reasonably valid measures of consumption for many nutrients and food groups in middle-aged screenees living in urban areas in Japan., 2011, 21, 6, 447, 458, Scientific journal, 10.2188/jea.je20100173

We also evaluated the validity of using a digital photographic image as a tool to assess the dietary intake of a food group. Participants in the study were 144 men and women living in urban areas of Japan who were asked to take pictures with a digital camera of all foods and beverages they consumed during 4 consecutive days. Simultaneous dietary records were used as the reference. The dietary intake was independently calculated from the two methods. We found that the variation in intake was high for such seasoning as salt which indicated that the degree of measurement error may be high when a representative portion size for such seasoning was used in a dish-based database. The estimated intake level by two methods was similar for green-yellow vegetables, fruit, fish, meat, eggs, milk and other dairy products, whereas the over/under-estimation for other food groups was too great to be used for accurate assessment. In contrast, the validity for ranking individuals by the estimated multiple-day intake was relatively high, with the exception of beverages, seasonings and spices., 01 Oct. 2009, 67, 5, 252, 259, 10.5264/eiyogakuzashi.67.252

  Results: The minerals excreted in the urine were significantly and positively correlated with each other, in which Na excretion was correlated with K and Ca excretion (r=0.490 and r=0.482, respectively, p<0.01) and Ca excretion was correlated with Mg excretion (r=0.526, p<0.01). The ratios of urinary exertion to dietary intake of Na, K, Ca, Mg, and P were 81.5%, 62.7%, 24.5%, 21.7%, and 56.1%, respectively. The dietary intake and the urinary excretion of the minerals expressed per body weight (kg) were significantly and positively correlated (Na, r=0.267; K, r=0.460; Ca, r=0.181; Mg, r=0.245; P, r=0.351, p<0.01). Further examinations using chief component analysis for food intake showed several significant positive correlations, including between Na intake and the intake of vegetables, noodles, and seasonings (r=0.332-0.381, p<0.01); between K, Mg and P intake and the intake of vegetables, fruits, and potatoes (r=0.332-0.533, p<0.01); and between Ca intake and the intake of bread and dairy foods (r=0.428, p<0.01). In addition, significant positive associations were found between Na excretion and the intake of confectionaries, nuts, and seeds (r=0.223, p<0.01). Weak correlations were also found between K excretion and the intake of vegetables (r=0.296, p<0.01); between Ca and P excretion and the intake of meat, oil, and fats (r=0.135, P<0.05; r=0.193, P<0.01, respectively), and between Mg excretion and the intake of bread and dairy foods (r=0.137, P<0.05).
  Conclusions: Findings from this study indicate that, while urinary excretion of Ca and Mg is unlikely to be a reliable biochemical marker of dietary intake, the levels of urinary excretion of Na, K, and P can be reflective of the intake of salt, vegetables, and meats, respectively. The urinary excretion of the minerals, particularly Na, K, and Ca, may be highly linked to salt intake in Japanese females., Jan. 2004, 59, 1, 23, 30, 10.1265/jjh.59.23

The intake of non-alcoholic beverages was estimated in 77 407 participants of the Japan Public Health Centre-based cohort study aged 45–74 years. The Cox regression calculated the hazard ratios (HR) and 95 % CI for incident CVD according to sex-specific quintiles of intake of non-alcoholic beverages. A total of 4578 incident CVD (3751 strokes and 827 CHD) were diagnosed during a 13·6-year median follow-up. The risks of stroke and total CVD were lower for the highest v. lowest intake quintiles of non-alcoholic beverages in men and women: the multivariable HRs (95 % CIs) were 0·82 (0·71, 0·93, P_trend = 0·005) and 0·86 (0·76, 0·97, P_trend = 0·02), respectively, in men and were 0·73 (0·63, 0·86, P_trend = 0·003) and 0·75 (0·65, 0·87, P_trend = 0·005), respectively, in women. The reduced risk was evident for both ischaemic and haemorrhagic strokes and was mainly attributable to green tea consumption. The intake of non-alcoholic beverages from coffee and other beverages was not associated with the risk of CVD in both men and women. Also, there was no association between the intake of non-alcoholic beverages and the risk of CHD in either sex. In conclusion, the risks of stroke and total CVD were lower with a higher intake of non-alcoholic beverages in Japanese men and women., 21 Jul. 2021, 1, 8, Scientific journal, 10.1017/s0007114521002737

Although myrosinase is inactivated by the cooking process, no studies have incorporated the effect of cooking into the estimation of dietary ITC intake or evaluated the validity. We evaluated the validity of dietary ITC intake estimated from a food frequency questionnaire (FFQ), and urinary ITC levels using 24 h urine samples or a WFR (weighed food record), and evaluated the reproducibility of dietary ITC in two FFQs administered at an interval of 1-year. SUBJECTS/METHODS: The JPHC-NEXT Protocol Area included a total of 255 middle-aged participants across Japan. We calculated dietary ITC intake from WFR and two FFQs by assuming that cooked cruciferous vegetables contain zero ITC. Urinary ITC excretion was measured at two points during summer and winter. The validity and reproducibility of dietary ITC intake estimated by FFQ were assessed using Spearman's correlation coefficients. RESULTS: Although we observed a moderate correlation between dietary ITC intake derived from a 12-day WFR and urinary ITC excretion, notwithstanding the cooking process, the correlation between dietary ITC intake estimated by FFQ and mean urinary ITC excretion was low. However, the correlation was improved when we compared urinary ITC excretion and a 3-day WFR or FFQ collected during winter. Our FFQ showed good reproducibility. CONCLUSION: Although seasonality is a critical factor, dietary ITC intake estimated using an FFQ showed moderate validity and reproducibility and can be used in future epidemiological studies., Mar. 2022, 76, 3, 462, 468, Scientific journal, True, 10.1038/s41430-021-00970-x

METHODS: The present analysis included 72,783 participants of the Japan Public Health Center-based Prospective Study. Participants who responded to the 5-year follow-up questionnaire in 1995-1999 were followed-up until December 2015. We estimated the risk of total and cause-specific mortality associated with GI and GL using Cox proportional hazards regression models. RESULTS: During 1,244,553 person years of follow-up, 7535 men and 4913 women died. GI was positively associated with all-cause mortality. As compared with the lowest quartile, the multivariable HR for those who had the highest quartile of GI was 1.14 (95% CI 1.08-1.20). The HRs for death comparing the highest with the lowest quartile were 1.28 (95% CI 1.14-1.42) for circulatory system diseases, 1.33 (95% CI 1.14-1.55) for heart disease, 1.32 (95% CI 1.11-1.57) for cerebrovascular disease, and 1.45 (95% CI 1.18-1.78) for respiratory diseases. GI was not associated with mortality risks of cancer and digestive diseases. GL showed a null association with all-cause mortality (highest vs lowest quartile; HR 1.04; 95% CI 0.96-1.12). However, among those who had the highest quartile of GL, the HRs for death from circulatory system diseases was 1.24 (95% CI 1.05-1.46), cerebrovascular disease was 1.34 (95% CI 1.03-1.74), and respiratory diseases was 1.35 (95% CI 1.00-1.82), as compared with the lowest quartile. CONCLUSION: In this large prospective cohort study, dietary GI and GL were associated with mortality risks., Dec. 2021, 60, 8, 4607, 4620, Scientific journal, True, 10.1007/s00394-021-02621-0

• Refereed, Journal of nutritional science, Validity of a food frequency questionnaire for the estimation of total polyphenol intake estimates and its major food sources in the Japanese population: the JPHC FFQ Validation Study., Nagisa Mori; Norie Sawada; Junko Ishihara; Ayaka Kotemori; Ribeka Takachi; Utako Murai; Masuko Kobori; Shoichiro Tsugane, We examine the validity and reproducibility of a food frequency questionnaire (FFQ) in a subsample of participants in the Japan Public Health Center-based Prospective Cohort Study using a database of polyphenol-containing foods commonly consumed in the Japanese population. Participants of the validation study were recruited from two different cohorts. In Cohort I, 215 participants completed a 28-d dietary record (DR) and the FFQ, and in Cohort II, 350 participants completed DRs and the FFQ. The total polyphenol intake estimated from the 28-d DR and FFQ were log-transformed and adjusted for energy intake by the residual method. Spearman correlation coefficients (CCs) between estimates from the FFQ and 28-d DR as well as two FFQs administered at a 1-year interval were computed. Median intakes of dietary polyphenols calculated from the DRs were 1172 mg/d for men and 1024 mg/d for women in Cohort I, and 1061 mg/d for men and 942 mg/d for women in Cohort II. The de-attenuated CCs for polyphenol intake between the DR and FFQ were 0⋅47 for men and 0⋅37 for women in Cohort I and 0⋅44 for men and 0⋅50 for women in Cohort II. Non-alcoholic beverages were the main contributor to total polyphenol intake in both men and women, accounting for 50 % of total polyphenol intake regardless of cohort and gender, followed by alcoholic beverages and seasoning and spices in men, and seasoning and spices, fruits and other vegetables in women. The present study showed that this FFQ had moderate validity and reproducibility and is suitable for use in future epidemiological studies., 2021, 10, e35, Scientific journal, True, 10.1017/jns.2021.25

We selected the following factors for inclusion in the estimates, namely tobacco smoking (active smoking and secondhand smoking), alcohol drinking, excess bodyweight, physical inactivity, infectious agents (Helicobacter pylori, hepatitis C virus, hepatitis B virus, human papilloma virus, Epstein-Barr virus, and human T-cell leukemia virus type 1), dietary intake (highly salted food, fruit, vegetables, dietary fiber, red meat, processed meat), exogenous hormone use, never breastfeeding and air pollution, given that these were considered modifiable, in theory at least. We first estimated the population attributable fraction (PAF) of each cancer attributable to these factors using representative relative risks of Japanese and the prevalence of exposures in Japanese around 2005, in consideration of the 10-year interval between exposure and cancer outcomes. Using nationwide cancer incidence and mortality statistics, we then estimated the attributable cancer incidence and mortality in 2015. We finally obtained the PAF for site-specific and total cancers attributable to all modifiable risk factors using this formula, with statistical consideration of the effect of overlap between risk factors. The results showed that 35.9% of all cancer incidence (43.4% in men and 25.3% in women) and 41.0% of all cancer mortality (49.7% in men and 26.8% in women) would be considered preventable by avoidance of these exposures. Infections and active smoking followed by alcohol drinking were the greatest contributing factors to cancer in Japan in 2015., 28 Feb. 2022, 4, 1, 26, 36, Scientific journal, False, 10.35772/ghm.2021.01037

• Refereed, Scientific reports, Sugary drink consumption and risk of kidney and bladder cancer in Japanese adults., Chi Yan Leung; Sarah Krull Abe; Norie Sawada; Junko Ishihara; Ribeka Takachi; Taiki Yamaji; Motoki Iwasaki; Masahiro Hashizume; Manami Inoue; Shoichiro Tsugane, Globally, sugary drinks are widely consumed, however, few epidemiologic studies have investigated the association between sugary drink consumption and risk of kidney and bladder cancer. We examined the association of sugary drinks with risk of kidney and bladder cancer in 73,024 participants from the Japan Public Health Center-based Prospective Study who reported no history of cancer. Sugary drink consumption was assessed using a validated food frequency questionnaire at study baseline (1995-1999). Individuals were followed to December 31, 2013. Multivariable Cox proportional hazards regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (CIs). During 1,069,815 person years of follow-up, 169 kidney cancer and 297 bladder cancer cases were documented. After adjusting for potential confounders, no greater risk of kidney and bladder cancer was observed. However, sugary drink consumption was positively associated with the risk of kidney cancer (HR for 100 ml/day increase in consumption was 1.11 [95% CI 1.01-1.22]) and bladder cancer (HR for 100 ml/d increase in consumption was 1.11 [95% CI 1.01-1.22]) among women after exclusion of cases diagnosed in the first three years of follow-up. In this large prospective cohort, consumption of sugary drinks was significantly associated with a small increase in hazard ratio for kidney and bladder cancer among women after exclusion of cases diagnosed within the first three years., 04 Nov. 2021, 11, 1, 21701, 21701, Scientific journal, True, 10.1038/s41598-021-01103-x

Relative contributions of household income and education to depression, as well as their interactions, have not been fully evaluated. This study aimed to examine the association between SES and depressive symptoms in Japanese adults, focusing on interactions between education and household income levels. METHODS: This cross-sectional study used data from baseline surveys of two cohort studies. Participants were 38,499 community-dwelling people aged 40-74 years who participated in baseline surveys of the Murakami cohort study (2011-2012) and Uonuma cohort study (2012-2015) conducted in Niigata Prefecture, Japan. Information regarding marital status, education level, household income, occupation, activities of daily living (ADL), and history of cancer, myocardial infarction, stroke, and diabetes was obtained using a self-administered questionnaire. Depressive symptoms were examined using the Center for Epidemiologic Studies Depression Scale (CES-D). Logistic regression analysis was used to obtain odds ratios (ORs). Covariates included age, sex, marital status, education, household income, occupation, ADL, and disease history. RESULTS: Individuals with higher education levels had lower ORs (adjusted P for trend = 0.0007) for depressive symptoms, independently of household income level. The OR of the university-or-higher group was significantly lower than that of the junior high school group (adjusted OR = 0.79). Individuals with lower household income levels had higher ORs (adjusted P for trend< 0.0001) for depressive symptoms, independently of education level. The type of occupation was not associated with depressive symptoms. In subgroup analyses according to household income level, individuals with higher education levels had significantly lower ORs in the lowest- and lower-income groups (adjusted P for trend = 0.0275 and 0.0123, respectively), but not in higher- and highest-income groups (0.5214 and 0.0915, respectively). CONCLUSIONS: Both education and household income levels are independently associated with the prevalence of depressive symptoms, with household income levels showing a more robust association with depressive symptoms than education levels. This suggests that a high household income level may offset the risk of depressive symptoms from having a low education level., 18 Nov. 2021, 21, 1, 2120, 2120, Scientific journal, True, 10.1186/s12889-021-12168-8

OBJECTIVES: This study aimed to evaluate the association of fruit and vegetable intake with all-cause, cancer, cardiovascular, and respiratory disease mortality in a Japanese cohort. METHODS: In the Japan Public Health Center-based prospective study, we included 94,658 participants (mean age; 56.4 ± 7.8 years, male; 46.0%) without cancer and cardiovascular disease at baseline. Information on fruit and vegetable intake was collected using a validated food frequency questionnaire. The Cox proportional-hazards model was used to estimate hazard ratios (HR) and 95% confidence intervals (CIs) of each quintile of fruit and vegetable intake, separately, in relation to all-cause and cause-specific mortality using the first quintile as a reference. Nonlinear associations were evaluated using a likelihood ratio test, comparing a linear model with a restricted cubic spline model. RESULTS: During a median of 20.9 follow-up years (interquartile range: 19.6-23.8), 23,687 all-cause deaths were documented. After adjusting for age, sex, and potential confounding factors, fruit and vegetable intake was nonlinearly and significantly associated with lower all-cause mortality, with the fourth and fifth quintiles having comparable HRs (fruit: fourth quintile, HR: 0.91; 95%CI: 0.87, 0.95, fifth quintile, HR: 0.92; 95%CI: 0.88, 0.96; P for nonlinearity < 0.001; vegetable: fourth quintile, HR: 0.92; 95%CI: 0.88, 0.97, fifth quintile, HR: 0.93; 95%CI: 0.89, 0.98; P for nonlinearity = 0.002). Fruit intake was significantly associated with lower cardiovascular mortality (HR in the fifth quintile: 0.91; 95%CI: 0.83, 0.99; P for nonlinearity = 0.01). CONCLUSIONS: In the Japanese population, higher intake of fruits and vegetables was nonlinearly associated with decreased all-cause mortality. These findings may contribute to the establishment of dietary recommendations for enhancing life expectancy in Asia., 28 Jun. 2022, 152, 10, 2245, 2254, Scientific journal, True, 10.1093/jn/nxac136

This study aimed to determine the effect of leisure-time and non-leisure-time PAs on dementia risk in middle-aged and older adults during an 8-year follow-up. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: Participants were 13,773 community-dwelling individuals aged 40-74 years who completed the baseline self-administered questionnaire survey of the Murakami cohort study in 2011-2013. METHODS: Main predictors were leisure-time and non-leisure-time (commute, occupational work, and housework) PAs as assessed by MET score (MET-hour/d). The outcome was newly developed dementia determined using a long-term care insurance database. Covariates included demographics, lifestyle, body size, disease history, and PA level. Hazard ratios (HRs) were calculated using Cox proportional hazards models. RESULTS: Mean age of participants was 59.0 (SD 9.3) years. Higher levels of leisure-time PA were associated with lower HRs (adjusted P for trend <.001), with all tertiles having significantly lower HRs (low: 0.71, 95% CI 0.51-0.99; medium: 0.59, 95% CI 0.43-0.81; high: 0.55, 95% CI 0.41-0.75) relative to the reference (zero). Higher quartiles of non-leisure-time PA were associated with lower adjusted HRs for dementia (adjusted P for trend < .001), with the second-fourth quartiles having significantly lower HRs (second: 0.73, 95% CI 0.54-0.98; third: 0.59, 95% CI 0.43-0.81; fourth: 0.55, 95% CI 0.41-0.75) relative to the lowest quartile. These associations were robust regardless of sex and age group. CONCLUSIONS AND IMPLICATIONS: Both leisure-time and non-leisure-time PAs are independently and robustly associated with a reduced risk of dementia., Jul. 2022, 23, 7, 1197, 1204, Scientific journal, True, 10.1016/j.jamda.2022.01.053

Physical activity (PA) is a potential preventive factor for falls. However, few studies have examined the effect of different types of PA on fall prevention. This study aimed to evaluate the association between PA levels and the incidence of recurrent falls by type of PA in middle-aged and older people. METHODS: This cohort study targeted 7,561 community-dwelling individuals aged 40-74 years who did not experience recurrent falls in the year before baseline. Information on PA levels, demographics, body size, lifestyle, and fall/disease history was obtained using a self-administered questionnaire in the baseline survey. Levels of total PA, leisure-time PA, and non-leisure-time PA (occupation, commuting, and housework) were estimated using metabolic equivalent (MET) scores (MET-h/day; hours spent on a given activity per day multiplied by its MET intensity). PA levels were categorized into four groups. Falls were recorded as none, once, or twice or more (recurrent falls). The outcome of the study was the incidence of recurrent falls in the past year before a survey conducted 5 years after the baseline survey. Logistic regression analyses were performed to calculate odds ratios for recurrent falls. RESULTS: Higher total PA and non-leisure-time PA levels were associated with a higher risk of recurrent falls (P for trend = 0.0002 and 0.0001, respectively), with the highest total PA and non-leisure-time PA groups having a significantly higher adjusted OR (1.96 [95%CI:1.33-2.88] and 2.15 [95%CI:1.48-3.14], respectively) relative to the lowest group (reference). As for leisure-time PA, the medium group had a significantly lower adjusted OR (0.70 [95%CI:0.49-0.99]) relative to the reference group. By sex, the adjusted OR in the medium leisure-time PA group was significantly lower relative to the reference group in women (0.50 [95%CI: 0.29-0.85]) but not in men. CONCLUSIONS: Medium level leisure-time PA reduces the risk of recurrent falls in middle-aged and older people, whereas higher level non-leisure-time PA is associated with a higher risk of recurrent falls., 02 Sep. 2022, 19, 1, 20, 20, Scientific journal, True, 10.1186/s11556-022-00300-5

• Refereed, The British journal of nutrition, Dietary sodium sources according to four 3-day weighed food records and their association with multiple 24-hour urinary excretions among middle-aged and elderly Japanese participants in rural areas., Fuyuka Ogawa; Ribeka Takachi; Junko Ishihara; Marina Yamagishi; Sachiko Maruya; Yuri Ishii; Kumiko Kito; Kazutoshi Nakamura; Junta Tanaka; Taiki Yamaji; Hiroyasu Iso; Motoki Iwasaki; Shoichiro Tsugane; Norie Sawada, Reducing sodium (Na) intake is an urgent global challenge, especially in East Asia and high-income Asia-Pacific regions. However, the sources of Na and their effects on urinary Na excretion have not been fully studied. We sought to clarify these sources and their association with urinary Na excretion. We examined four 3-day weighed food records and five 24-h urinary collections from each of 253 participants in Japan, aged 35-80 years, between 2012 and 2013. We compared the levels of Na according to four categories: foods contributing to discretionary or nondiscretionary Na intake, the situation in which dishes were cooked and consumed, food groups and types of cuisine. We also conducted regression analysis in which 24-h urinary Na excretion was a dependent variable and the amounts of food intake in the four categories were independent variables. Levels of Na were the highest in discretionary intake (60.6%) and in home-prepared dishes (84.0%). Of the food groups, miso soup showed the highest percentage contribution to Na intake (13.3%) after seasonings such as soy sauce. In the regression analysis, the standardised coefficient for foods of nondiscretionary Na sources was larger than that for discretionary sources, whereas that for home-prepared dishes was consistent with the levels of Na in those foods. Pickled products, followed by fresh fish and shellfish, miso soup and rice, were associated with high urinary Na excretion. Thus, discretionary foods (such as miso soup) contribute the most to Na consumption, although nondiscretionary intake (such as pickled vegetables) may influence urinary Na excretion., 18 Aug. 2022, 129, 11, 1, 23, Scientific journal, True, 10.1017/S0007114522002653

However, FFQs have been widely used for ranking individuals in a population based on their dietary intake. We determined the validity of sodium (salt equivalent) intake, potassium intake, and sodium-to-potassium (Na/K) ratio obtained using the FFQ for identifying individuals who deviated from the dietary reference intakes (DRIs) measured using multiple 24-h urinary excretion measurements or 12-day weighed food records (WFR). This study included 235 middle-aged subjects. The correlation coefficients (CCs) between the FFQ and WFR estimates were mostly moderate (0.24-0.54); the CCs between the FFQ and 24-h urinary excretion measurements were low or moderate (0.26-0.38). Values of area under the receiver-operating curve (AUC) at the point of DRIs for salt equivalent or potassium were >0.7 with the WFR as the reference standard and 0.60-0.76 with the 24-h urinary excretion as the reference standard. Using both standard measures, the AUC for the Na/K ratio was <0.7. The accuracy of salt equivalent and potassium intake estimation using the FFQ to determine absolute intake point was comparable to that using WFR, allowing for quantified error, but not as good as that of 24-h urinary excretion., 23 Jun. 2022, 14, 13, Scientific journal, True, 10.3390/nu14132594

• Not Refereed, Journal of nutritional science and vitaminology, New Environmental-Related Approaches to Improved Eating Behavior and Nutrition across One's Life Course., Ribeka Takachi; Sachiko Maruya; Junko Ishihara, It is worthwhile to discuss new environmental-related approaches to eating behavior that are effective throughout one's life course for better nutrition. Salt-reduction programs for children may benefit from strategies that actively engage families and teachers, according to a school-based cluster randomized controlled trial (School-EduSalt) in China to reduce salt intake in children and their families. Considering young people's lifestyle, a population-based approach for healthy low-risk people is necessary; for example, the use of an educational song consisting of interesting sounds and lyrics as BGM may be effective. Self-monitoring of salt intake or salt concentrations in home seasoning by a versatile salinity meter may be another effective educational approach in reducing salt intake by raising the individual's awareness on their rate of salt intake. Further, shift workers have increased risk of diet-related chronic conditions due to their eating habits. Moreover, mental illnesses among workers require nutritional approaches because they may have effects on subsequent weight changes. Finally, studies for the eldery suggest the importance of a nutritional approach especially for males living alone to prevent or improve frailty. A three-month approach that included nutritional education for the elderly reduced frailty, and the effects persisted post-intervention. These results are quite encouraging for nutritionists in their efforts to create a vibrant society, despite its incredibly age., 2022, 68, Supplement, S58-S60, Scientific journal, False, 10.3177/jnsv.68.S58

The present cohort study aimed to determine this association in older adults, using a method for measuring vitamin D levels which is more accurate than those used in previous studies. METHODS: Participants were 3447 individuals aged 40-74 years without depressive symptoms at baseline who participated in the 5-year follow-up survey. The baseline investigation, including a self-administered questionnaire survey and blood collection, was conducted in 2011-2013. Plasma 25-hydroxyvitamin D (25[OH]D) levels were measured, and divided into overall quartiles summed up by sub-quartiles and stratified by age, sex, and season. The outcome was depressive symptoms determined by the CES-D (11-item, cut-off score of 6/7) 5 years later. Covariates were demographics, lifestyles, baseline CES-D score, and disease history. RESULTS: Mean plasma 25(OH)D levels were 58.0 nmol/L in men and 45.7 in women (P < 0.0001), and cumulative incidences of depressive symptoms were 249/1577 (15.8 %) in men and 313/1870 (16.7 %) in women (P = 0.4526). The lower 25(OH)D quartile group had higher adjusted ORs in men and women combined (P for trend = 0.0107) and women (P for trend = 0.0003), but not in men. Adjusted ORs of the lowest quartile group were significantly higher than the highest group in men and women combined (OR = 1.39, 95 % CI: 1.06-1.81) and women (OR = 1.89, 95 % CI: 1.31-2.72). LIMITATION: Depressive symptoms were self-reported. CONCLUSIONS: Low vitamin D levels were associated with a high risk of depressive symptoms, especially in women. Women are thus considered a major target for preventing vitamin D deficiency to address depression., 03 Jan. 2023, 325, 48, 54, Scientific journal, True, 10.1016/j.jad.2022.12.104

Few investigations have compared survivors' diets to their original pre-diagnosis dietary pattern or with the patterns of cancer-free controls. We examined the dietary changes in survivors for five years (i.e. before to after diagnosis) in cancer survivors, comparing them with cancer-free controls in a prospective cohort study in Japan. Using 1995-1998 for the baseline and 2000-2003 for the follow-up survey, a validated food frequency questionnaire was administered to 33,643 men and 39,549 women aged 45-74 years. During the follow-up period, 886 men and 646 women had developed cancer. Participants that had not been diagnosed with cancer served as controls. There was a greater decrease in the calorie intake (median change: - 168 kcal/d [Interquartile range: - 640, 278]) in male cancer survivors compared to controls (- 33 kcal/d [- 453, 380], P < .001). On comparison with cancer-free controls, multiple linear regression analysis revealed a significantly larger reduction in energy-adjusted ethanol intake for male cancer survivors (β =  - 0.36). There was no difference in changes in fruit and vegetable or red meat intake and no other significant differences in dietary changes between survivors and controls for either gender. This suggests that most dietary changes in survivors after cancer diagnosis are not systematically different from those that occur in people without a cancer diagnosis., 18 Jan. 2023, 13, 1, 982, 982, Scientific journal, True, 10.1038/s41598-023-27820-z

OBJECTIVE: This study aimed to clarify sex differences in the association between BMI and dementia risk in community-dwelling people. METHODS: This cohort study with an 8-year follow-up targeted 13,802 participants aged 40-74 years at baseline in 2011-2013. A self-administered questionnaire requested information on body size, including height, weight, and waist circumference (the values of which were validated by direct measurement), socio-demographics, lifestyle, and disease history. BMI was calculated and categorized as < 18.5 (underweight), 18.5-20.6 (low-normal), 20.7-22.7 (mid-normal), 22.8-24.9 (high-normal), 25.0-24.9 (overweight), and≥30.0 kg/m2 (obese). Incident cases of dementia were obtained from the long-term care insurance database. A Cox proportional hazards model was used to calculate multivariable-adjusted hazard ratios (HRs). RESULTS: The mean age of participants was 59.0 years. In men, higher BMI was associated with lower dementia risk (fully-adjusted p for trend = 0.0086). In women, the association between BMI and dementia risk was U-shaped; the "underweight," "low-normal," and "overweight" groups had a significantly higher risk (fully-adjusted HR = 2.12, 2.08, and 1.78, respectively) than the reference ("high-normal" group). These findings did not change after excluding dementia cases which occurred within the first four years of the follow-up period. CONCLUSION: Overweight/obese women, but not men, had an increased risk of dementia, suggesting that sex differences in adiposity might be involved in the development of dementia., 19 Jun. 2023, 94, 3, 949, 959, Scientific journal, True, 10.3233/JAD-230294

This study aimed to estimate the economic burden of cancer attributable to major lifestyle and environmental risk factors in Japan in 2015. We evaluated the economic cost of cancer attributable to modifiable risk factors from a societal perspective. We obtained the direct medical costs for 2015 from the National Database of Health Insurance Claims and Specific Health Checkups of Japan, and estimated the indirect costs of premature mortality and of morbidity due to cancer using the relevant national surveys in Japan. Finally, we estimated the economic cost of cancer associated with lifestyle and environmental risk factors. The estimated cost of cancer attributable to lifestyle and environmental factors was 1,024,006 million Japanese yen (\) (8,460 million US dollars [$]) for both sexes, and \673,780 million ($5,566 million) in men and \350,226 million ($2,893 million) in women, using the average exchange rate in 2015 ($1 = \121.044). A total of \285,150 million ($2,356 million) was lost due to premature death in Japan in 2015. Indirect morbidity costs that could have been prevented were estimated to be \200,602 million ($1,657 million). Productivity loss was highest for stomach cancer in men (\28,735 million/$237 million) and cervical cancer in women (\24,448 million/$202 million).

This study aimed to examine longitudinal associations between alcohol consumption, smoking, and dementia risk in middle-aged and older Japanese people. METHODS: This study used a cohort design with an 8-year follow-up. Participants were community-dwelling Japanese people (N = 13,802) aged 40-74 years. The baseline survey, including a self-administered questionnaire, was conducted in 2011-2013. Predictors were alcohol consumption and tobacco smoking. The outcome was incident dementia obtained from a long-term care insurance database. Covariates were demographics, lifestyle factors, body mass index, general health status, and history of stroke, diabetes, and depression. RESULTS: Participant mean age was 59.0 years. The 1-149, 150-299, and 300-449 g ethanol/week groups had significantly lower adjusted hazard ratios (HRs) (0.62, 0.59, and 0.47, respectively) compared with the reference group, with no significant linear association. HRs increased toward 1 when past-drinkers and those with poor health status and a disease history were excluded (0.80, 0.66, and 0.82, respectively). Higher smoking levels were dose-dependently associated with a higher HR (adjusted P for trend = 0.0105), with the ≥20 cigarettes/day group having a significantly higher adjusted HR (1.80). Heavy drinkers (≥449 g ethanol/week) with smoking habits, but not those without smoking habits, had higher dementia risk (P for interaction = 0.0046).

Prospective cohort studies have typically measured polyphenol concentrations in a single blood sample and the reproducibility of plasma polyphenol measurements is largely unknown. OBJECTIVE: We evaluated the reproducibility of 35 plasma polyphenols collected at an interval of 1-year. We also examined correlations of these polyphenols with food group intakes calculated from weighed food records (WFR) and food frequency questionnaire (FFQ). METHODS: The study included 227 middle-aged participants from the JPHC-NEXT Protocol Area in Japan. We measured 35 polyphenols in plasma collected at two points 1-year apart. Food group intakes were calculated from 12-day WFR and FFQ. For the reproducibility analysis, the intraclass correlation coefficient (ICC) of 35 polyphenol concentrations were examined between the two points. Pearson's partial correlations was used to assess the correlation between polyphenols and food groups. RESULTS: Moderate- to high ICCs were observed for tea-originated polyphenols such as gallic acid, quercetin, epigallocatechin, and kaempferol - and coffee-derived polyphenols, such as caffeic acid, and ferulic acid. For the dietary analyses, moderate correlations were observed for non-alcoholic beverages intake and epigallocatechin, epicatechin, catechin, and gallic acid. For green tea, higher correlations were observed with these polyphenols. CONCLUSION: Plasma concentrations of tea and coffee-related polyphenols, except for catechin, had good reproducibility over a 1-year period. The correlations between intake of non-alcoholic beverages, particularly green tea, and tea polyphenols, indicated moderate- to high correlations., Jan. 2024, 78, 1, 34, 42, Scientific journal, True, 10.1038/s41430-023-01349-w

We evaluated the validity of estimated intakes of sugars, amino acids and fatty acids using a long-food frequency questionnaire (FFQ) among middle-aged and elderly Japanese. METHODS: From 2012 to 2013, 240 men and women aged 40-74 years from five areas in the JPHC-NEXT protocol were asked to respond to the long-FFQ and provide a 12-day weighed food record (WFR) as reference. The long-FFQ, which included 172 food and beverage items and 11 seasonings, was compared with a 3-day WFR, completed during each distinct season, and validity was assessed using Spearman's correlation coefficients. RESULTS: Percentage differences based on the long-FFQ with the 12-day WFR in men and women varied from -83.9% to 419.6%, and from -75.8% to 623.1% for sugars, -17.5% to 2.8% and -5.8% to 19.6% for amino acids, and -58.5% to 78.8% and -43.4% to 129.3% for fatty acids, respectively. Median values of correlation coefficients for the long-FFQ in men and women were 0.52 and 0.42 for sugars, 0.38 and 0.37 for amino acids, and 0.42 and 0.42 for fatty acids, respectively. CONCLUSIONS: The long-FFQ provided reasonable validity in estimating the intakes of sugars, amino acids, and fatty acids in middle-aged and elderly Japanese. Although caution is warranted for some nutrients, these results may be used in future epidemiological studies., 06 Jan. 2024, Scientific journal, False, 10.2188/jea.JE20230132

DESIGN: A cohort study. SETTING: Communities in Japan. PARTICIPANTS: Participants were 7540 community-dwelling volunteers aged 40-74 years (N=7540). The baseline survey was a self-administered questionnaire conducted between 2011-2013. Predictors were presence of chronic pain in the knee, foot or ankle, and low back, with the degree of pain categorized as none, very mild/mild, moderate, or severe/very severe. Covariates in the multivariate model of chronic pain in a site were demographics, body mass index, physical activity level, disease history, and chronic pain in the other 2 sites. Logistic regression analysis was used to calculate odds ratios (ORs). INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): Recurrent falls in the year before the 5-year follow-up survey. RESULTS: Mean participant age was 60.2 years. Higher degrees of chronic pain were associated with higher odds of recurrent falls for the knee (P=.0002) with a higher OR of 1.48 (95% CI: 1.11-1.97), for the foot or ankle (P=.0001) with a higher OR of 1.97 (95% CI: 1.36-2.86), and for the low back (P=.0470) with a higher OR of 1.45 (95% CI: 1.09-1.91) in those with any degree of pain relative to those without pain. Higher degrees of chronic knee pain were associated with higher odds of recurrent falls in women (P=.0005), but not in men (P=.0813). Meanwhile, higher degrees of chronic low back pain were associated with the odds of recurrent falls in men (P=.0065), but not in women (P=.8735). CONCLUSIONS: Chronic pain in the knee, foot or ankle, and lower back was independently and dose-dependently associated with a higher risk of recurrent falls. A marked sex-dependent difference was also noted in the association., Mar. 2024, 105, 3, 498, 505, Scientific journal, True, 10.1016/j.apmr.2023.09.021

• Scientific reports, Development and preliminary validation of a prediction formula of sodium and sodium-to-potassium ratio based on multiple regression using 24-h urines., Marina Yamagishi; Ribeka Takachi; Junko Ishihara; Sachiko Maruya; Yuri Ishii; Kumiko Kito; Kazutoshi Nakamura; Junta Tanaka; Taiki Yamaji; Hiroyasu Iso; Motoki Iwasaki; Shoichiro Tsugane; Norie Sawada, Accurate measurement of sodium intake in the diet is challenging, and epidemiological studies can be hampered by the attenuation of associations due to measurement error in sodium intake. A prediction formula for habitual 24-h urine sodium excretion and sodium-to-potassium ratio might lead to more reliable conclusions. Five 24-h urinary samples and two Food Frequency Questionnaires (FFQs) were conducted among 244 Japanese participants aged 35-80 years. We conducted multivariate linear regression analysis with urinary excretion as dependent variables and eating behaviour and food frequency as independent variables. Empirical weights of sodium excretion and sodium-to-potassium ratio were extracted. Preliminary validity was also assessed by randomly dividing the subjects into development and validation groups based on the correlation coefficient between estimates by the prediction formula and urinary excretion. Taste preference, soy sauce use at the table, frequency of pickled vegetables intake and number of bowls of miso soup were extracted as determinants of sodium excretion. Correlation coefficients between the estimates and urinary excretion for men and women were 0.42 and 0.43, respectively, for sodium and 0.49 and 0.50, respectively, for sodium-to-potassium ratio. This prediction formula may provide more accurate estimation of sodium intake and sodium-to-potassium ratio than the food composition approach., 27 Apr. 2024, 14, 1, 9704, 9704, Scientific journal, True, 10.1038/s41598-024-60349-3

• Kidney & blood pressure research, Associations of Urinary and Dietary Sodium-To-Potassium Ratios with Albuminuria in Community-Dwelling Japanese Adults: A Cross-Sectional Study., Keiko Kabasawa; Ribeka Takachi; Kazutoshi Nakamura; Norie Sawada; Shoichiro Tsugane; Yumi Ito; Junta Tanaka; Ichiei Narita; Kunihiro Matsushita, INTRODUCTION: The urinary sodium-to-potassium ratio is an indicator of dietary sodium intake and has been associated with reduced kidney function. However, less is known about its association with albuminuria, the other key component of chronic kidney disease, in the community-dwelling adult population. We examined the association of the spot urinary sodium-to-potassium ratio with albuminuria and compared spot urinary and dietary sodium-to-potassium ratios. METHODS: We quantified the association of the urinary sodium-to-potassium ratio with albuminuria in 6,274 Japanese adults (aged 40-97 years; 50.9% women) based on spot urine samples. We performed linear and logistic regression modeling to account for potential confounders. Elevated albuminuria was defined as a spot urinary albumin-to-creatinine ratio (ACR) ≥30 mg/g. We secondarily evaluated the dietary sodium-to-potassium ratio based on a food-frequency questionnaire. RESULTS: The median spot urinary and dietary sodium-to-potassium ratios were 2.70 (interquartile interval, 1.87-3.83) and 1.50 (1.21-1.84), respectively. The median ACR was 11.0 (6.0-24.0) mg/g. In a multivariable linear regression model, the spot urinary sodium-to-potassium ratio (per increment) was significantly associated with the natural logarithm of the ACR (regression coefficient, 0.023 [95% confidence interval {95% CI}, 0.007-0.038]). This result was consistent in a multivariable logistic regression model (adjusted odds ratio, 1.08 [95% CI: 1.04-1.12]). The corresponding estimates for the dietary sodium-to-potassium ratio were 0.139 (95% CI: 0.087-0.191) and 1.28 (95% CI: 1.14-1.45), respectively. CONCLUSIONS: Both spot urinary and dietary sodium-to-potassium ratios were associated with elevated albuminuria in community-dwelling Japanese adults. Our findings further support the potential usefulness of the spot urinary sodium-to-potassium ratio as an indicator of sodium intake and suggest a link between sodium intake and kidney damage., 2022, 47, 9, 576, 585, Scientific journal, True, 10.1159/000526277

This study aimed to determine longitudinal associations between smoking, alcohol consumption, and fall risk in middle-aged and older people. METHODS: Participants of this cohort study were 7542 community-dwelling Japanese people aged 40-74 years. The baseline self-administered questionnaire survey was conducted in 2011-2013, and the second survey was conducted 5 years later. Predictors were smoking level and alcohol consumption. The outcome was the occurrence of recurrent falls. Information on self-reported falls in the previous year was obtained. Covariates were demographics, lifestyle factors, body mass index, general health status, and disease history. RESULTS: The mean age of participants was 60.3 years. Higher smoking levels were associated with a higher recurrent fall risk (adjusted P for trend = 0.0386), with the ≥20 cigarettes/day group having a higher risk (adjusted odds ratio [OR] = 1.93, 95% confidence interval [CI]: 1.20-3.10) than lifetime non-smokers. The association between smoking and recurrent fall risk tended to be stronger in drinkers than in non-drinkers (adjusted OR = 2.75, 95% CI: 1.57-4.81), suggesting a potential interaction (P for interaction = 0.1035). Although there were no dose-dependent associations between alcohol consumption and recurrent fall risk overall, moderate alcohol consumption (150-299 g ethanol/week) was associated with a lower risk (adjusted OR = 0.57, 95% CI: 0.33-0.98) compared with no consumption in men. CONCLUSIONS: Smoking, but not alcohol consumption, is dose-dependently associated with high fall risk. However, moderate alcohol consumption may be associated with a decreased fall risk. Moreover, there may be a potential interaction between smoking and alcohol consumption on fall risk. Geriatr Gerontol Int 2024; ••: ••-••., 07 Dec. 2024, Scientific journal, False, 10.1111/ggi.15040

• Grant-in-Aid for Research Activity Start-up, Apr. 2010, Mar. 2012, 22800069, Principal investigator, External validity for estimating dietary intakes using a recipe based dish-database and the estimation of salt intake., TAKACHI Ribeka, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Niigata University, 0, 0, 0, We collected existing dietary record data from different populations in Japan for the purpose of dietary assessment using recipe based typical dish-database. Data included names of mixed dishes or food names for single foods, ingredient foods, and their weights. We examined the external validity for estimating dietary intakes using a recipe based dish-database among an urban population that differ from the area where the database was developed. The applicability for estimating dietary intakes using the recipe based dish-database for urban populations was suggested. Furthermore, taste preference was suggested to be a defining feature of whole dietary salt intake, and therefore an improvement of estimation of whole salt intake can be expected through the application of self-reported taste preference to an assessment system using recipe based dish-database., Competitive research funding, kaken

From the discussion with the researchers, we planned to make a dish-based food table for Japanese and also to verify the rule to take photographs for this particular application. We developed the dish-based food composition table using the data of National Health and Nutrition Survey in Japan. From a verification assessment, it was found that the rule to take photographs for this application may not be appropriate when taking photographs of Japanese diet., kaken

We distributed a lifestyle questionnaire to 13,816 people, aged between 40 and 74 years, residing in Murakami City, Sekikawa Village, and Awashimaura Village in Niigata Prefecture, and collected them from 8,487 (61.4%). During the follow-up period, we observed 373 deaths, 284 osteoporotic fracture cases, and 429 osteoarthritis cases. Using these data, we were able to analyze risk factors for deaths, osteoporotic fracture, osteoarthritis, and chronic pain. Also, we were able to reevaluate exposure variables by comparing base-line and 5-year-follow-up information on lifestyles., kaken
