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.
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.
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).
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.
很少有研究探讨口腔功能与使用身体功能测试分类的身体前虚弱状态之间的关系。本横断面研究旨在澄清九州福冈县itosima 虚弱研究中社区居住的老年人之间的这种关联。
在邀请参加研究的 1555 人中，有 381 人（188 名男性和 193 名女性）参加。他们的身体前虚弱状态使用由两个身体指标（疲劳和非故意体重减轻，通过问卷确定）、两个功能成分（步行速度下降和肌肉无力，使用身体功能测量仪器确定）和下降的身体活动（使用三轴加速度计检查）组成的分类系统进行评估。随后，将这些个体分为三组：强壮、前虚弱和虚弱。同时检查了剩余牙齿数量、咀嚼性能、舌压强度和口腔交替发音（ODK）等口腔功能。收集了有关社会活动和运动习惯的数据，并测量了个体的身体成分。使用逻辑回归模型计算身体前虚弱的优势比（OR）和 95%置信区间（CI）。
在这项研究中，126 名（33%）参与者表现出身体前虚弱。强壮组的参与者比前虚弱组更年轻、握力更强、行走速度更快（p<0.001）。强壮组的口腔功能更好（咀嚼性能，p=0.015；口腔 ODK/ta/，p=0.004）。前虚弱状态与年龄（OR，1.111；95%CI，1.048-1.178；p<0.001）、咀嚼性能（OR，0.819；95%CI，0.680-0.986；p=0.035）、低 ODK/ta/（OR，1.864；95%CI，1.069-3.250；p=0.028）和低社会活动（OR，2.273；95%CI，1.308-3.951；p=0.004）显著相关。
本研究表明，年龄较大、前舌运动较低、咀嚼性能较低和社会活动较低的老年人与身体前虚弱呈正相关。
