Several studies are limited by verifying the level of physical activity with questionnaires and not through objective measurement in older adults. This article aims to analyze the association between a low level of physical activity with accelerometry) and mobility limitation in older adults. A population-based cross-sectional study conducted with 543 older adults. Multiple regression analysis was performed using hierarchical analysis, grouping the variables into two blocks ordered according to the precedence with which they acted on the outcomes. Among the evaluated older adults, 13.7% presented mobility limitations and among these 60.39% were in the low level of physical activity group. Older adults with a low level of physical activity (OR = 3.49 [2.0 - 6.13]), aged 75 and over (OR = 1.97 [1.03 - 3.72]), living without a partner (OR = 2.01 [1.09 - 3.68]), having difficulty performing basic (OR = 2.49 [1.45 - 4.28]) and instrumental (OR = 2.28) [1.18 - 4.36]) activities of daily life, and multimorbidity (OR = 2.06 [1.04 - 4.08]) were independently associated with mobility limitation. A low level of physical activity increases the chance of mobility limitation in older adults, regardless of sociodemographic and clinical variables.
几项研究受到限制，因为它们仅通过问卷调查来验证老年人的身体活动水平，而没有通过客观测量来验证。本文旨在分析身体活动水平低（通过加速度计测量）与老年人活动受限之间的关系。这是一项基于人群的横断面研究，共纳入了 543 名老年人。采用分层分析进行多元回归分析，将变量分为两个块，按对结果的作用先后顺序分组。在所评估的老年人中，有 13.7%存在活动受限，其中 60.39%属于身体活动水平低的群体。身体活动水平低的老年人（OR = 3.49 [2.0-6.13]）、75 岁及以上的老年人（OR = 1.97 [1.03-3.72]）、没有伴侣的老年人（OR = 2.01 [1.09-3.68]）、基本日常生活活动有困难的老年人（OR = 2.49 [1.45-4.28]）和工具性日常生活活动有困难的老年人（OR = 2.28 [1.18-4.36]）以及患有多种疾病的老年人（OR = 2.06 [1.04-4.08]）与活动受限独立相关。身体活动水平低会增加老年人活动受限的机会，无论其社会人口学和临床变量如何。
