Key Points Question Is the amount and intensity of physical activity associated with total and site-specific fracture among postmenopausal women who participated in the Women’s Health Initiative study? Findings In this cohort study of 77 206 postmenopausal women with a mean follow-up of 14 years, higher amounts of total, mild, moderate to vigorous, and walking physical activity were significantly associated with lower risk of hip fracture. Positive associations existed for moderate to vigorous physical activity with wrist or forearm fractures and for sedentary behavior with total fractures. Meaning Regular physical activity, including lighter-intensity activities, and less sedentary time is associated with reduced risk of fracture in older women.
