Physical activity (PA) is a recognized contributor to healthy aging. However, the majority of studies exploring its associations with adverse outcomes in cohorts of older adults use single‐time PA estimates, which do not consider its dynamic nature. The aim of the present study is to explore the presence of different PA trajectories in the Toledo Study of Healthy Aging and their association with adverse outcomes. Our hypothesis is that prospectively maintaining or increasing PA is associated with a reduced risk of adverse outcomes.

托莱多健康老龄化研究中的体力活动轨迹、死亡率、住院和残疾。

体力活动 (PA) 是公认的健康老龄化贡献者。然而，在老年人队列中探索其与不良结果相关性的大多数研究使用单次 PA 估计值，而未考虑其动态性质。本研究的目的是探讨托莱多健康老龄化研究中不同 PA 轨迹的存在及其与不良结果的关联。我们的假设是前瞻性地维持或增加 PA 与降低不良结果的风险相关。
