Background Older adults are vulnerable to oral frailty due to factors such as age, education level, physical condition, and limited access to medical resources. Given that oral frailty can lead to adverse outcomes and is often overlooked by policymakers and health professionals, it is important to understand the current state of oral frailty among community-dwelling older adults. Design Systematic review and meta-analysis. Methods Two researchers independently conducted searches in seven databases, extracted data, and assessed the quality of eligible studies. Data from cross-sectional studies or cohort studies with a clear definition of oral frailty. Stata 14.0 was utilized to evaluate the overall prevalence of oral frailty, while Cochrane's Q, I 2 statistics were employed to assess statistical heterogeneity. Results A total of 15 studies were ultimately included in this analysis. The pooled prevalence of oral frailty among community-dwelling older adults was 32% (95% CI: 24%−40%, I 2 = 98.9%, P < 0.001). By country, the prevalence was 53% (95% CI: 42%−65%) in China and 22% (95% CI: 19%−39%) in Japan. The incidence of oral frailty was 29% (95% CI: 18%−39%) among those aged 74 and over and 26% (95% CI: 16%−36%) among those under 74. The prevalence of oral frailty was 46% (95% CI: 31%−60%) as assessed by the OFI-8 scale, 18% (95% CI: 14%−22%) using the OF-6 scale, and 37% (95% CI: 34%−39%) with the OFI-5 scale. The rates of oral frailty reported before 2021 and between 2...
