| Outline of Final Research Achievements |
Purpose of this study was to examine the association between dietary factors, daily life function, and frailty risk in Japanese elderly. A Higher frequency of vegetables, fruits and green tea showed a statistically significant positive association with oral health-related quality of life score.
The higher dietary protein intake was inversely associated with the frailty risk in men and women. In addition, the association between dietary protein intake and 7 domains: higher dietary protein intake was associated with sociological frailty in men. In women, higher dietary protein intake was associated with physical frailty.

| Academic Significance and Societal Importance of the Research Achievements |
日本人高齢者を対象に、食事因子が生活機能‐特に口腔機能‐やフレイルとの関連について検討を行った。その結果、抗酸化作用を持つ食品（野菜・果物や緑茶）およびたんぱく質の摂取は、口腔関連QOLスコアを高め、フレイルリスクを低下させた。これの食品を多く摂取することは、生活機能の維持・増進、フレイルの予防、延いては介護予防につながる可能性が示唆された。
