Abstract:

Introduction: Several studies are limited by verifying the level of physical activity with questionnaires and not through objective measurement (accelerometry) in older adults. Aim: To analyze the association between a low level of physical activity with accelerometry) and mobility limitation in older adults. Methods: A population-based cross-sectional study conducted with 543 older adults (mean: 76.2 years). 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. Results: 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. Conclusion: A low level of physical activity increases the chance of mobility limitation in older adults, regardless of sociodemographic and clinical variables.
