Outline of Final Research Achievements |
Study 1: A survey of community-dwelling older adults revealed an association between oral frailty and solitary eating. In addition, a 6-year longitudinal study showed that decreased salivary secretion was influenced by decreased appetite. Study 2: A cross-sectional and longitudinal study among community-dwelling older persons investigated oral factors as predictors of the development of physical frailty. Both cross-sectional and longitudinal data analyses indicated that xerostomia was a significant associated factor for the development of physical frailty.

Academic Significance and Societal Importance of the Research Achievements |
本研究課題によって、孤食や食欲の低下は、オーラルフレイル発現のサインとなりうる可能性が示された。さらに、口腔乾燥感の訴えは、将来的な身体的フレイルの発現の予測因子となる可能性が示された。口腔の健康状態と全身の健康状態は密接な関連性を持つことから、加齢に伴う口腔機能の軽微な低下の兆候に早期発見するための、評価項目を明らかにすることができた。
