Physical Activity Patterns and Variability, Cognitive Performance, and Dementia in the National Health and Aging Trends Study.

ABSTRACT:

Introduction

Physical activity is a modifiable risk factor for dementia. However, the potential reverse effect of adverse cognitive change on physical activity remains underexplored.

Methods

Cross-sectional analysis of a subset of National Health and Aging Trends Study (NHATS; N = 706) U.S. Medicare beneficiaries. Dementia status (dementia vs. no dementia) was classified per NHATS protocol. Cognitive performance was assessed in executive function, orientation, and memory domains. Daily physical activity was assessed using wrist-worn accelerometers (Actigraph Insight).

Results

Compared with participants living without dementia, participants living with dementia had lower daily activity counts (×1000) (-319.3; 95% confidence interval (CI), -471.0 - -167.5), lower activi
