Cognitive Decline Trajectories and Time-of-Day Physical Activity Patterns: The ARIC Neurocognitive Study

Abstract

Cognitive decline may influence physical activity (PA) patterns in late life, but how cognitive trajectories differentially impact PA throughout the day remains unexplored. We established cognitive trajectories in 2,140 initially cognitively unimpaired Atherosclerosis Risk in Communities participants (mean age 74.1±4.5 years, 59.
