Physical activity and osteoporosis hip fracture in postmenopausal women
Studies from 1968 on postmenopausal osteoporosis, osteoporotic hip fracture, and fundamentally the association betwen physical activity and hip fractures in postmenopausal women are reviewed. Physical activity has been related to enhanced bone mass and improved physical functioning and thus may reduce the risk for osteoporotic hip fracture. All the studies suggest a protectiv effect of physical activity with regard to hip fractures reducing the risk of later fracture by up to 50%. Higher levels of leisure time, sport activity, and household chores and fewer hours of sitting daily were associated with a significantly reduced relative risk for hip fracture after adjustment for age, dietary factors, falls, and functional and health status. Low-intensity activities may be the most prudent recommendation for sedentary older women.
KEY WORDS: Osteoporosis, hip fracture, physical activity, postmenopausal women.
