Background/Study: The occurrence of sarcopenia and sarcopenic obesity (SO) may be associated with modifiable behavioral factors such as insufficient physical activity (PA) and sedentary behavior. Thus, the aim of this study was to analyze the association of total physical activity (PA) and its different domains, as well as sedentary behavior with sarcopenia and SO in older adults with the incidence of clinical factors.Methods: Body composition was measured by dual energy X-ray absorptiometry (DXA), handgrip strength by dynamometer, physical function by physical tests, and PA and sedentary behavior were self-reported.Results: Older adults with low gait speed (HR = 5.99, 95%CI = 2.07-17.24 and HR = 4.44, 95%CI = 1.37-14.41) and insufficiently active in the occupational domain presented a higher risk of sarcopenia, independent of others PA domains, total PA and sedentary behavior. Older adults with low muscle mass (HR = 3.71, 95%CI = 1.15-11.96), low gait speed (HR = 4.15, 95%CI = 1.38-12.50), and high body fat (HR = 3.82; 95%CI = 1.18-12.37) and insufficiently active in the locomotion domain presented a higher risk of SO, independent of sex and age.Conclusion: The risk of sarcopenia and SO is higher in older adults with the incidence of clinical factors who are insufficiently active in the occupational and locomotion domains, respectively.

进行体育活动可降低老年人发生肌肉减少症和肌肉减少症的风险，并具有以下临床因素：24个月前瞻性研究。

背景/研究：少肌症和少肌症肥胖（SO）的发生可能与可改变的行为因素有关，例如体力活动不足（PA）和久坐行为。因此，本研究的目的是分析老年人的总体育活动（PA）及其不同域的关联以及久坐行为与肌肉减少症和SO的关系以及临床因素的发生率。自我报告双能X线骨密度仪（DXA），测功机的握力，体格检查的身体机能以及PA和久坐行为。结果：低步态速度的老年人（HR = 5.99，95％CI = 2.07- 17.24和HR = 4.44，95％CI = 1.37-14.41），并且在职业领域中活动不足会导致少肌症的发生风险较高，而与其他PA域无关，总PA和久坐行为。肌肉质量低（HR = 3.71，95％CI = 1.15-11.96），步态低速（HR = 4.15，95％CI = 1.38-12.50）和高脂肪（HR = 3.82; 95％CI = 1.18-12.37）且在运动领域内活动不足会导致发生SO的风险较高，而与性别和年龄无关。结论：老年人的肌肉减少症和SO发生风险较高，并且在职业中活动不足的临床因素的发生率也较高和运动域。
