BACKGROUND/OBJECTIVES: Physical activity (PA) could be effective in the prevention of functional disability in older women, especially for those with body composition abnormalities. The aim this study was to analyze the association of total PA and in different domains with physical function and functional capacity in older women with or without osteosarcopenic obesity (OSO), as well as to assess the risk of functional disability in osteosarcopenic obesity older women insufficiently active.
SUBJECTS/METHODS: The study included 152 Brazilian older women, aged 60 years and older. Body composition was measured by dual energy X-ray absorptiometry (DXA) and physical function by physical tests. Functional capacity and PA were self-reported.
In older women without OSO, the practice of leisure-time exercise (β:-0.23; 95%CI -0.40 to -0.06) and total PA (β:-0.40; 95%CI -0.57 to -0.23) is inversely associated with dependence in ADL. In older women with OSO, the practice of leisure-time exercise was inversely associated with physical function (β:0.88; 95%CI 0.31-1.46) and functional capacity (β:-1.05; 95%CI 1.64 to -0.45), while total PA (β:-1.03; 95%CI -1.93 to -0.13) was inversely associated with functional capacity, independent of control variables. In addition, older women with OSO who remained insufficiently active in leisure-time exercise (HR:2.28; 95%CI 1.04-4.99) and locomotion (HR:2.62; 95%CI 1.28-5.36) domains presented risk for functional disability.
PA is inversely associated with physical function and functional capacity in older women with or without OSO, and older women with OSO who are insufficiently active in leisure-time exercise and locomotion domains presented a higher risk for functional disability.
背景/目的：体力活动（PA）可能对预防老年女性的功能障碍有效，尤其是对那些身体成分异常的女性。本研究旨在分析总体力活动和不同领域的体力活动与有或无肌骨减少性肥胖（OSO）的老年女性的身体功能和功能能力之间的关系，并评估体力活动不足的肌骨减少性肥胖老年女性发生功能障碍的风险。
受试者/方法：本研究纳入了 152 名巴西老年女性，年龄在 60 岁及以上。身体成分通过双能 X 射线吸收法（DXA）测量，身体功能通过身体测试测量。功能能力和 PA 是自我报告的。
在无 OSO 的老年女性中，休闲时间运动（β：-0.23；95%CI-0.40 至-0.06）和总 PA（β：-0.40；95%CI-0.57 至-0.23）与日常生活活动的依赖呈负相关。在有 OSO 的老年女性中，休闲时间运动与身体功能（β：0.88；95%CI0.31-1.46）和功能能力（β：-1.05；95%CI1.64 至-0.45）呈负相关，而总 PA（β：-1.03；95%CI-1.93 至-0.13）与功能能力呈负相关，独立于控制变量。此外，在休闲时间运动和（HR：2.28；95%CI1.04-4.99）和移动（HR：2.62；95%CI1.28-5.36）领域活动不足的有 OSO 的老年女性发生功能障碍的风险增加。
PA 与有或无 OSO 的老年女性的身体功能和功能能力呈负相关，在休闲时间运动和移动领域活动不足的有 OSO 的老年女性发生功能障碍的风险更高。
