This cross-sectional study aimed to demonstrate the association between physical frailty subdomains and oral frailty. This study involved community-dwelling older adults (aged ≥65 years). Physical frailty was assessed with the Japanese version of the Cardiovascular Health Study criteria. Oral frailty was defined as limitations in at least three of six domains. Logistic regression analysis was used to analyze the association between physical frailty risk and oral frailty. In addition, we examined the association between physical frailty subdomains (gait speed, grip strength, exhaustion, low physical activity, and weight loss) and oral frailty. A total of 380 participants were recruited for this study. Overall, 18% and 14% of the participants were at risk of physical frailty and had oral frailty, respectively. Physical frailty risk (odds ratio (OR) = 2.40, 95% confidence interval (CI): 1.22-4.75, = 0.012) was associated with oral frailty in multivariate analysis. In secondary analysis, among physical frailty subdomains, gait speed (OR = 0.85, 95% CI: 0.73-0.97, = 0.019) was associated with oral frailty. The present findings suggest that physical frailty is closely related to oral frailty. Among physical frailty subdomains, decreased gait speed in particular is an important indicator related to the development of oral frailty.
这项横断面研究旨在证明身体虚弱子领域与口腔虚弱之间的关联。该研究纳入了社区居住的老年人（年龄≥65岁）。使用日本版心血管健康研究标准评估身体虚弱状况。口腔虚弱定义为六个领域中至少三个领域存在功能受限。采用逻辑回归分析来分析身体虚弱风险与口腔虚弱之间的关联。此外，我们还研究了身体虚弱子领域（步速、握力、疲惫、低体力活动和体重减轻）与口腔虚弱之间的关联。本研究共招募了380名参与者。总体而言，分别有18%和14%的参与者存在身体虚弱风险和口腔虚弱。在多变量分析中，身体虚弱风险（比值比（OR）=2.40，95%置信区间（CI）：1.22 - 4.75，P = 0.012）与口腔虚弱相关。在二次分析中，在身体虚弱子领域中，步速（OR = 0.85，95%CI：0.73 - 0.97，P = 0.019）与口腔虚弱相关。本研究结果表明，身体虚弱与口腔虚弱密切相关。在身体虚弱子领域中，尤其是步速降低是与口腔虚弱发展相关的一个重要指标。
