ABSTRACT
This study examined the relationship between walking and cognitive function among Chicago Health and Aging Project participants. Data collection occurred during six 3-year cycles, of which Cycles 4-6 were used for this specific analysis. Information was obtained regarding walking frequency and duration, demographics, chronic conditions, cognitive activities, apolipoprotein E4, physical function, and cognitive function (global and domains). A composite walking measure was developed and categorized as follows: no walking, ≤105 min/week, and >105 min/week. Mixed-effects regression analyses tested associations between walking and global cognitive function, episodic memory, and perceptual speed. The sample consisted of 4,320 participants (African American/Black: 65%; female: 65%; mean education: 13 years; mean age: 75 years). Composite or total walking had a statistically significant association with global cognitive function and perceptual speed, after adjustments were made.
