2002 DEC 5 - (NewsRx.com & NewsRx.net) -- Increasing leisure time activity is associated with a lower risk of hip fractures in postmenopausal women, according to Diane Feskanich, ScD, Walter Willett, MD, DrPH, and Graham Colditz, MD, DrPH, of Brigham and Women's Hospital and Harvard Medical School, Boston, who conducted a study to assess the relationship of walking, leisure-time activity, and risk of hip fracture among postmenopausal women.
The team's results were published in the November 13, 2002 issue of the Journal of the American Medical Association, a theme issue on aging, and presented at a JAMA media briefing on aging.
According to background information in the article, physical activity can reduce the risk of hip fractures in older women, although the required type and duration of activity have not been determined. Previous studies have suggested that the risk of hip fracture can be reduced by 20-50% for active compared with sedentary adults. Walking is the most common activity among older adults, and evidence suggests that it can increase femoral bone density and reduce fracture risk.
The study consisted of analysis of data from 12 years of follow-up (beginning in 1986) in the Nurses' Health Study cohort of registered nurses within 11 U.S. states. Included in the study were a total of 61,200 postmenopausal women (aged 40-77 years and 98% white) without diagnosis of cancer, heart disease, stroke, or osteoporosis at baseline.
"After controlling for age, body mass index, use of postmenopausal hormones, smoking, and dietary intakes in proportional hazards models, risk of hip fracture was lowered by 6% for each increase of 3 ...
