OBJECTIVE This study aimed to determine the prevalence of sarcopenic obesity and its association with the level of physical activity, alone and combined with sedentary behavior. METHODS A cross-sectional study was performed. The sample was composed of 317 women aged between 24 and 59 years. Sarcopenic obesity was determined by the coexistence of sarcopenia (reduced muscle mass and strength) and obesity (% fat). Dual-energy x-ray absorption was used to evaluate muscle mass and % fat, with cutoff points of <15 kg and <31.71%, respectively. Strength was assessed by the handgrip test, with a cutoff point of <21.68 kg. Levels of physical activity and sedentary behavior were assessed using the long version of the International Physical Activity Questionnaire. Individuals who did not achieve 150 minutes per week of physical activity were considered insufficiently active. The cutoff point for sedentary behavior was determined based on the 75th percentile (480 min/wk), considering excessive sedentary behavior (≥75th percentile) and low/moderate sedentary behavior (<75th percentile). RESULTS The prevalence of sarcopenic obesity was 7.9% (95% CI, 4.9-10.8). Sarcopenic obesity was associated with the general physical activity level (odds ratio, 3.96; 95% CI, 1.32-11.8) and being insufficiently active together with low/moderate sedentary behavior (odds ratio, 4.88; 95% CI, 1.49-16.0). CONCLUSIONS There was the presence of sarcopenic obesity in adult women which was associated with the level of general physical activity, alone and combined with sedentary behavior.

女性肌肉减少性肥胖的患病率及其与独立身体活动水平结合久坐行为的相关性。


目的 本研究旨在确定肌肉减少性肥胖的患病率及其与单独和结合久坐行为的身体活动水平的相关性。方法 进行横断面研究。样本由 317 名年龄在 24 至 59 岁之间的女性组成。肌肉减少性肥胖是由肌肉减少症 （肌肉质量和力量减少） 和肥胖 （脂肪百分比） 的共存决定的。双能 X 射线吸收用于评估肌肉质量和脂肪百分比，截断点分别为 <15 kg 和 <31.71%。通过握力测试评估力量，分界点为 <21.68 kg。使用长版国际身体活动问卷评估身体活动水平和久坐行为。每周没有达到 150 分钟体育锻炼的人被认为不够活跃。久坐行为的分界点是根据第 75 个百分位 （480 分钟/周） 确定的，考虑到过度久坐行为 （≥第 75 个百分位） 和低/中度久坐行为 （<第 75 个百分位）。结果 肌肉减少性肥胖的患病率为 7.9% （95% CI，4.9-10.8）。肌肉减少性肥胖与一般体力活动水平 （比值比，3.96;95% CI，1.32-11.8） 和活动不足以及低/中度久坐行为 （比值比，4.88;95% CI，1.49-16.0） 相关。结论 成年女性存在肌肉减少性肥胖，这与一般体力活动水平有关，单独和结合久坐行为。
