Armstrong MEG, Lacombe J, Wotton CJ, et al. - In the population-based prospective UK Million Women Study, researchers analyzed the risk of fracture at 7 different sites correlated with 7 different types of physical activity. In total, 371,279 postmenopausal women, mean age was 59.8 years, rating their health as good or excellent and reporting participation in walking, cycling, gardening, doing housework, yoga, dance and sports club activities, were followed for site-specific incident fracture by record linkage to national databases on day-case and overnight hospital admissions. Numbers with a first site-specific fracture during an average follow-up of 12 years were: humerus, forearm, wrist, hip, femur (not neck), lower leg, and ankle. There was no significant heterogeneity by type of activity for hip fractures, but there was a significant 15-20% declines in risk related to walking for 1 hour/day and partaking in yoga and sporting activities. Findings suggested that physical activity is a modifiable risk factor for fracture, but the results vary between different activities and fracture sites.
