Objective: To determine how physical activity at various ages over the life course is associated with cognitive impairment in late life. Results: Women who reported being physically active had lower prevalence of cognitive impairment in late life compared to women who were inactive at each time. When the four times were analyzed together, teenage physical activity was most strongly associated with lower odds of late-life cognitive impairment. However, women who were physically inactive at teenage and became active in later life had lower risk than those who remained inactive. Conclusions: Women who reported being physically active at any point over the life course, and especially at teenage, have lower likelihood of cognitive impairment in late life. Interventions should promote physical activity early in life and throughout the life course.
