Abstract

This study investigated the direct and indirect associations of physical activity and sedentary behavior with survival time in older adults. Prospective population-based cohort study used exploratory survey-type methods and physical performance tests in 319 adults aged ≥60 years. Trajectory diagrams were used to represent the initial hypothetical and final models with the relationships of independent, mediating, and dependent variables. Physical activity was indirectly associated with survival time and was mediated by instrumental activities of daily living and functional performance. In contrast, instrumental activities of daily living, functional performance, the number of hospitalizations, and medications mediated the association between duration of sedentary behavior and survival time. The explanatory power of the final model was 19%. Future efforts should focus on increasing the participation and adherence of older adults to exercise programs to improve their physical functions and general health, which may increase their health period and, consequently, their survival time.
