• 査読あり, 英語, Nutrients, Short-Term Effects of Salt Restriction via Home Dishes Do Not Persist in the Long Term: A Randomized Control Study., Sachiko Maruya; Ribeka Takachi; Maki Kanda; Misako Nakadate; Junko Ishihara, Salt intake reduction is crucial to prevent non-communicable diseases (NCDs) globally. 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., 2020年10月03日, 12, 10, 研究論文（学術雑誌）, 国際誌, 10.3390/nu12103034

• 英語, 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., 2022年08月18日, 1, 23, 研究論文（学術雑誌）, 国際誌, 10.1017/S0007114522002653
• 英語, Nutrients, Validity of the Food Frequency Questionnaire-Estimated Intakes of Sodium, Potassium, and Sodium-to-Potassium Ratio for Screening at a Point of Absolute Intake among Middle-Aged and Older Japanese Adults., Tomoka Matsuno; Ribeka Takachi; Junko Ishihara; Yuri Ishii; Kumiko Kito; Sachiko Maruya; Kazutoshi Nakamura; Junta Tanaka; Kazumasa Yamagishi; Taiki Yamaji; Hiroyasu Iso; Motoki Iwasaki; Shoichiro Tsugane; Norie Sawada, Using Food Frequency Questionnaires (FFQs) to compare dietary references for screening has been in high demand. 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., 2022年06月23日, 14, 13, 研究論文（学術雑誌）, 国際誌, 10.3390/nu14132594

Hence, we aimed to examine the applicability of a web-based 24-hour dietary recall (24HR) tool to large-scale epidemiological studies by determining the sampling rate and characteristics of randomly selected participants (partially entire population) from a Japanese cohort study. METHODS: In total, 5,013 individuals were recruited from a cohort of 21,537 individuals, and 975 agreed to participate in this study. The participants selected either self-administered web-based dietary 24HR (self-administered 24HR) or interviewer-administered telephone-based 24HR (interviewer-administered 24HR) as the method for the dietary assessment and answered questions regarding the acceptability of the system. RESULTS: The response rate of the 975 participants was 19.4%, and approximately 4.5% of the total study population. About half of them chose the self-administered 24HR (46.9%). The median time required for the self-administered and interviewer-administered 24HR was 25 and 27 minutes, respectively. In the self-administered 24HR, older people, regardless of sex, tended to require a longer time, and approximately 60% of the participants rated the ease of use of the system as "somewhat difficult" or "difficult." CONCLUSIONS: Characteristics of the participants in this study were not systemically different from those of the entire study population. Improvements in approach for the entering cooking details and the dish name selection may be necessary for better acceptability in order to be accepted as a self-administered 24HR., 2022年03月19日, 研究論文（学術雑誌）, 国内誌, 10.2188/jea.JE20220071
• 英語, 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年, 68, Supplement, S58-S60, 研究論文（学術雑誌）, 国内誌, 10.3177/jnsv.68.S58
