Educational Corporation Kagawa Nutrition Academy Joshiei Yo University (Chairman: Akio Kagawa) and Nisshin Oilli Group Co., Ltd. (President: Takahisa Kuno) aim to contribute to the prevention and improvement of frailty, which is one of the important health issues in an aging society. In December 2022, we began joint research to verify the usefulness and feasibility of the smartphone app “Balance Diary – 10 Food Group Checks” for nutritional guidance. (Press release at the

) Through a clinical trial lasting approximately one year, we found that an intervention program (nutritional diagnosis and improvement activities) using the app was easily implemented, and at the same time, significant improvements in food intake diversity scores and frailty-related indicators were confirmed. These results will be presented at the 83rd General Meeting of the Japanese Society of Public Health (Sapporo, October 29-31, 2024) and the 19th Annual Meeting of the Japanese Society of Applied Gerontology (Yokohama, November 9-10, 2024). It was announced on [Research overview] Local governments in Saitama Prefecture are recruiting local residents over the age of 65 who wish to participate, and they will be asked to record their meals (daily) on the smartphone app “Balance Diary – Check 10 Food Groups” and take regular health classes (once every two weeks). I was asked to attend for three months. We investigated whether these interventions could be implemented without difficulty, and whether the intervention resulted in improvements in food diversity scores (DVS) and frailty-related indicators. The 54 participants who met the participation criteria were randomly divided into two groups: the early intervention group (group A) and the late intervention group (group B). During the first three months, only group A was given the intervention, while group B was kept on a waiting list. group, or the control group.

We compared changes in food diversity score (DVS) and frailty-related indicators before and after each intervention.

Record the intake of 10 food groups every day using “Balance Diary ~10 Food Group Check~” 2. Participation in the “health class (nutrition guidance and light exercise guidance)” held once a week Measurement sessions were held before and after the intervention period Main endpoint: Food intake diversity score (DVS) Secondary endpoints: Indicator for checking frailty risk (CL15), intake by food group and nutrient, Weight, body mass index (BMI), body composition (lean mass index, body fat mass index), Muscle strength (grip strength), lower limb function (time to stand and sit on chair 5 times) [Summary of research results] Both groups had high levels of continuity and usability in using the app, and were also highly satisfied with the health classes. Furthermore, during the follow-up period, more than 80% of participants in Group A continued to record using the app. In terms of food diversity score (DVS), significant improvements were observed after the intervention in both groups (Figure 2: Group A, average increase of 2.1 points; Group B, average increase of 1.2 points), which is at the desired level in terms of frailty prevention. The percentage of participants with a certain DVS score of 7 or higher (intake of 7 or more food groups per day on average) also increased significantly (Group A: 38.5% → 73.1%, Group B: 26.9% → 61.5%). In addition, significant improvements were observed in both groups in the time taken to stand and sit five times, an indicator of lower limb function, and with regard to body composition, BMI significantly improved in Group A after the follow-up period. [Conclusion] 1. An intervention (intervention program) that combines the use of the smartphone app “Balance Diary ~10 Food Group Checks~” and regular health classes (nutritional guidance and light exercise guidance) is extremely effective in improving food diversity score (DVS). I found it to be effective. 2. Improvements were also seen in body mass index (BMI) and lower limb function, demonstrating the effect on frailty-related indicators. 3. The intervention program was shown to be reasonably easy to implement. 4. Even after the
intervention program ended, the awareness and practice of consuming a variety of foods each day continued.
