Outline of Final Research Achievements |
It revealed by the cross-sectional study enrolled 3564 participants in the latter-stage older adults who received oral health examinations that the medical expenditure showed significant differences in participants who had subjective oral frailty symptoms including difficulties in eating tough foods and difficulties in swallowing tea or soup when compared to that of healthy participants. Six-year longitudinal study revealed that participants with oral frailty at baseline had significantly higher medical expenditures among 538 participants without certified nursing care. In addition, those with oral frailty or with less than 19 teeth present were shown to have a higher possibility for the occurrence of disability or mortality. On the other hand, 51 older adults were surveyed as an intervention study. It showed that the group continued oral exercise had an improvement in the total score of oral frailty items and in tongue and lip motor function during the observation period.

Academic Significance and Societal Importance of the Research Achievements |
「固いものが食べにくい」「お茶や汁物でむせる」などの後期高齢者の主観的オーラルフレイルは、その後の健康状態への悪影響と医療費の増加に関連すること、継続した健口体操がオーラルフレイルの改善に寄与する可能性が示された。 以上の結果から、高齢者の一般健康診断にオーラルフレイル評価を組み込み、早期の健口体操を含めたオーラルフレイル介入を促進することで、要介護状態のリスクを回避するための施策となる可能性がある。また、オーラルフレイル対策は将来的な医療費の削減にもつながる可能性が示唆された。
