Factors Associated With 5-Year Risk of Hip Fracture in Postmenopausal Women

Abstract
The estimated 329 000 hip fractures that occur annually in the United States1 are associated with high morbidity, mortality, and cost.2 Prevention of hip fracture is a high priority for patients, physicians, and public health. Several studies and consensus opinions have investigated the risk factors for hip fractures.3-8 The Study of Osteoporotic Fractures (SOF),3 which included 7782 women over 5 years, set the benchmark for establishing risk of hip fracture to date. The number of women included in the Women's Health Initiative (WHI) is an order of magnitude larger than SOF, and WHI includes nearly 20% minority women.
