Physical activity reduces risk for cognitive impairments
Methods. Participants were 376 community-dwelling older women aged 70-80 years at baseline from the Women's Health and Aging Study (WHAS) II. Cox proportional hazard models, adjusted for age, race, education, number of chronic illnesses, and number of depressive symptoms at baseline, were used to evaluate the associations between self-reported physical activity and risk of cognitive impairments in psychomotor speed, executive function, and verbal memory.
Results. Greater baseline levels of caloric expenditure were associated with up to a 2.3% reduction in risk of impairments in executive function, verbal memory, and psychomotor speed (p's<0.05).
Conclusions. These findings demonstrate that even modest increases in baseline levels of physical activity appear beneficial to the long-term maintenance of cognitive health in late life.
