Physical activity trajectories and cognitive decline among older adults in China: a longitudinal cohort study.

ABSTRACT:

Background

Cognitive decline is a critical public health concern among older adults. While physical activity (PA) is a recognized modifiable factor for mitigating cognitive deterioration, the specific impact of long-term PA trajectories on the rate of cognitive decline remains understudied, particularly in China.

Methods

A longitudinal cohort of 3,471 participants aged ≥ 60 years from the China Health and Retirement Longitudinal Study (CHARLS) was analyzed. PA trajectories were identified via group-based trajectory modeling (GBTM) on the basis of self-reported PA data from four waves (2011, 2013, 2015, and 2018). Global cognitive function, assessed by episodic memory and mental intactness, was measured repeatedly. Associations between PA trajectories and cognitive decline we
