A Pilot Survey: Oral Function as One of the Risk Factors for Physical Frailty

The aim of this study was to examine the association of the multiple facets of oral, motor, and social functions in community-dwelling older adults, to identify factors that might influence the risk of frailty. Of the 82 participants included in the study, 39 (5 males and 34 females) were young-old adults, with an average age of 70.5 ± 2.8 years, and 43 (14 males and 29 females) were old-old adults, with an average age of 78.7 ± 2.9 years. We assessed the risk factors for frailty among oral, motor, and social functions. Statistical analysis showed a significant difference in the oral diadochokinesis between the groups ( = 0.006). According to the Spearman correlation analysis, a significant association was observed with age and oral diadochokinesis (rs = -0.262, = 0.018), and social support (rs = -0.219, = 0.049). Moreover, binomial logistic regression analysis revealed a significant association of frailty with the occlusal force (odds ratio, 0.031; 95% confidence interval (95% CI), 0.002-0.430; = 0.010), General Oral Health Index (odds ratio, 0.930; 95% CI, 0.867-0.999, = 0.046), and availability of social support (odds ratio, 0.803, 95% CI, 0.690-0.934, = 0.004). To prevent frailty at an early stage, assessments of oral functions, and also that of the availability of social support, are important.
