Background: Few studies have examined the relationship between oral functions and the physical pre-frailty status, classified using physical function tests. This cross-sectional study aimed to clarify this association among community-dwelling older people from the Itoshima Frail Study in Itoshima Fukuoka Prefecture. Methods: Of the 1,555 individuals invited to join the study, 381 (188 males and 193 females) enrolled. Their physical pre-frailty was assessed with a classification system consisting of two physical indicators (fatigue and unintentional weight loss, determined with a questionnaire), two functional components (declined walking speed and muscle weakness, determined using a body function measuring instrument), and declined physical activity (examined using a triaxial accelerometer). Subsequently, the individuals were classified into three groups: robust, pre-frailty, and frailty. Along with the number of teeth remaining, oral functions, such as masticatory performance, tongue pressure strength, and oral diadochokinesis (ODK), were examined. Data regarding social activity and exercise habits were collected, and the individuals’ body compositions were measured. Odds ratios (ORs) and 95% confidence intervals (CIs) for the physical pre-frailty were calculated using logistic regression models. Results: In this study, 126 (33%) participants presented with physical pre-frailty. The participants in the robust group were younger, had stronger maximum handgrip strength, and walked faster than those in the physical pre-frailty group (p < 0.001). The robust group presented with better oral functions (masticatory performance, p = 0.015; oral ODK /ta/, p = 0.004). The physical pre-frailty status was significantly associated with age (OR, 1.111; 95% CI, 1.048–1.178; p < 0.001), masticatory performance (OR, 0.819; 95% CI, 0.680–0.986; p = 0.035), low ODK/ta/ (OR, 1.864; 95% CI, 1.069–3.250; p = 0.028), and low social activity (OR, 2.273; 95% CI, 1.308–3.951; p = 0.004). Conclusion: This study indicated that older people with higher age, lower anterior tongue movement, lower masticatory performance, and lower social activity are positively associated with physical pre-frailty.

Introduction: It is known that oral frailty is one of the risk factors for physical frailty. Therefore, early detection, appropriate treatment, and prevention of oral frailty are really important. Tongue lifting exercise has been identified as a well-known method for improving decreased tongue pressure, one of the factors for oral frailty. However, few reports have investigated how tongue-strengthening exercises affect physical function and body composition. The aim of this study was to investigate the effects of isometric tongue lifting exercises on oral function, physical function, and body composition. Methods: Participants were 49 elderly people aged 68-79 years, who had previously participated in the "Itoshima Frail Study."Participants performed isometric tongue lift exercises for 3 months. Oral function (tongue pressure and oral diadocokinesis), physical function (grip strength, open-eyed one-leg standing, sit-to-stand motion time, 5-m gait speed, and 3-m Timed up and go [TUG]), and body composition were measured at baseline and post-intervention, and the extent of changes in each item was statistically analyzed. Furthermore, participants were divided into physical frailty/pre-frailty and robust groups based on the Japanese version of the frail scale proposed by [BMC Geriatr. 2015 Apr;15:36] and were compared in terms of the extent of changes in each item baseline and the post-intervention. Results: After the intervention, oral function increased significantly together with a significant improvement in physical function, open-eyed one-leg standing time, sit-to-stand motion, and 3-m TUG. For body composition, visceral fat level and basal metabolic rate decreased significantly. Although no significant change in body composition was observed in the physical frailty/pre-frailty group after the intervention, significant improvements in several items were observed in the robust group. Conclusion: Isometric tongue lifting exercise can effectively improve oral function. Furthermore, it might affect physical function and body composition.

地域在住高齢者42名(男性23名、女性19名、平均年齢73.1±3.1歳)を対象に、1日3回、1週間に3日以上の実施を指示した舌挙上運動訓練を3ヵ月間実施し、その身体機能や体組成に与える影響を、介入前後の比較から検討した。フレイル/プレフレイル群(11名)と非フレイル群(31名)に分け比較検討した結果、両群で舌圧、オーラルディアドコキネシスといった口腔機能に加え、椅子立ち座り時間、5m歩行速度、3mアップ・アンド・ゴー時間(3mTUG)の身体機能で有意な改善がみられた。一方、非フレイル群では、皮下脂肪率、骨代謝率、基礎代謝量といった体組成においても有意な改善が認められたのに対し、フレイル/プレフレイル群では改善を認めなかった。
