The time spent in different physical activity (PA) intensities is associated with sarcopenia risk for community-dwelling older women.
To evaluate the role of sitting time and physical activity (PA) level as predictors of sarcopenia odds.
In a cross-sectional study, physically independent older women (n = 67) performed the six-minute walk test to identify functional limitation (≤ 400 m). Sedentary time (as sitting time) and PA (light, moderate and vigorous) were obtained with the International Physical Activity Questionnaire (IPAQ). Sarcopenia was diagnosed as recommended by the Society of Sarcopenia, Cachexia and Wasting Disorders (SCWD). Sarcopenia odds (low muscle mass and functional limitation) was predicted by binary logistic regression, considering the weekly sitting time and PA as independent variables.
Sarcopenia prevalence was 7.5% (n = 5), with functional limitation present in 38.8% (n = 26), and low muscle mass in 22.4% (n = 15). The predictive model (p = 0.014) involved moderate PA as the only significant predictor (OR = 0.999; p = 0.005; 95% CI: 0.998-1.000) of functional limitation. Moderate PA prevents sarcopenia odds. Each weekly hour of moderate PA decreased sarcopenia odds by 6%.
Time spent in moderate PA can prevent sarcopenia.
社区居住的老年女性处于不同的身体活动(PA)强度下所花费的时间与肌肉减少症风险相关。
评估久坐时间和身体活动(PA)水平作为肌肉减少症几率预测因子的作用。
在一项横断面研究中,身体独立的老年女性(n=67)进行了六分钟步行测试,以确定功能受限(≤400 米)。久坐时间(如坐立时间)和 PA(低强度、中强度和高强度)使用国际体力活动问卷(IPAQ)获得。肌肉减少症按照肌肉减少症、恶病质和消耗综合征协会(SCWD)的建议进行诊断。考虑每周久坐时间和 PA 作为自变量,使用二项逻辑回归预测肌肉减少症几率(低肌肉量和功能受限)。
肌肉减少症患病率为 7.5%(n=5),功能受限者占 38.8%(n=26),低肌肉量者占 22.4%(n=15)。预测模型(p=0.014)仅涉及中等 PA 作为唯一显著预测因子(OR=0.999;p=0.005;95%CI:0.998-1.000),与功能受限相关。中等 PA 可预防肌肉减少症几率。每周增加一小时中等 PA 可使肌肉减少症几率降低 6%。
中等 PA 时间的花费可以预防肌肉减少症。
