Assessment of Leisure Time Physical Activity and Brain Health in a Multiethnic Cohort of Older Adults.

ABSTRACT:

Importance

Results from longitudinal studies suggest that regular leisure time physical activity (LTPA) is associated with reduced risk of dementia or Alzheimer disease. Data on the association between LTPA and brain magnetic resonance imaging (MRI) measures remain scarce and inconsistent.

Objective

To examine the association of LTPA and MRI-assessed brain aging measures in a multiethnic elderly population.

Design, setting, and participants

This cross-sectional study included 1443 older (≥65 years) adults without dementia who were participants of the Washington/Hamilton Heights-Inwood Columbia Aging Project study. LTPA, from self-reported questionnaire, was calculated as metabolic equivalent of energy expenditure. Both moderate to vigorous LTPA, assessed as meeting Ph
