OBJECTIVE: To investigate the factors associated with lower limb (LL) muscle weakness in older adults residing in a small municipality in Northeastern Brazil.
METHODS: This population-based, cross-sectional epidemiological study included 194 older adults. Independent variables included socioeconomic, behavioral, and health-related factors. The outcome was defined by poor performance on the 30-second chair stand test. Poisson regression with robust variance was used to estimate Prevalence Ratios (PR) and corresponding 95 % Confidence Intervals (CI).
RESULTS: The prevalence of LL muscle weakness was 30.40 %. A higher probability of LL muscle weakness was observed among individuals of advanced age (PR: 1.05; 95 % CI: 1.021.07), those who reported smoking (PR: 2.31; 95 % CI: 1.23-4.42), were insufficiently active (PR: 1.98; 95 % CI: 1.13-3.46), or exhibited high sedentary behavior (PR: 1.72; 95 % CI: 1.08-2.72).
CONCLUSION: Advanced age, insufficient physical activity, high sedentary behavior, and tobacco use were positively associated with LL muscle weakness in the study population.
