Outline of Final Research Achievements

Frailty was assessed using a five-items: (1) weight loss, (2) walking speed, (3) exercise habits, (4) memory, and (5) fatigue. The Frailty Score increased from 1.35 to 1.43 in a questionnaire survey of 1,235 Nishinomiya City residents, comparing the 2020 survey with the 2021 survey. The study also found that the group with a low dietary variety score was twice as likely to develop flailty as the group with a high dietary variety score. In addition, those who participated in health classes that focused on exercise and nutritional guidance had better physical fitness indicators than those who did not participate.
Thus, although activity limitation increased the risk of frailty, the implementation of health classes was effective in preventing its progression.

Academic Significance and Societal Importance of the Research Achievements

感染症拡大防止のための活動制限は、高齢者においてフレイルのリスクとなりうる。さらに、食生活において、摂取する食品の種類が少ないこともフレイルの発症と関連することがわかった。よって、積極的な運動などにより身体活動量を高めることと、摂取する食品の多様性を高めることがフレイル予防のために重要であると考える。それぞれの人にあった方法で、これらのことを達成できる方法を模索していくべきである。
