Abstract

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.

高龄、吸烟、体力活动不足和久坐行为与老年人下肢肌肉无力相关：一项横断面研究

目的探讨巴西东北部一个小城市老年人下肢肌无力的相关因素。方法：这项以人群为基础的横断面流行病学研究包括194名老年人。独立变量包括社会经济、行为和健康相关因素。结果是在30秒的椅架测试中表现不佳。采用稳健方差的泊松回归来估计患病率（PR）和相应的95%置信区间（CI）。结果：腰系肌无力患病率为30.40%。老年个体中LL肌无力的概率更高(PR: 1.05；95% CI: 1.021.07)，报告吸烟的人(PR: 2.31；95% CI: 1.23-4.42)，活动不足(PR: 1.98；95% CI: 1.13-3.46)，或表现出高久坐行为(PR: 1.72；95% ci: 1.08-2.72)。结论：在研究人群中，高龄、体力活动不足、久坐行为和吸烟与LL肌无力呈正相关。
