CONTEXT Raloxifene hydrochloride, a selective estrogen receptor modulator, prevents bone loss in postmenopausal women, but whether it reduces fracture risk in these women is not known. OBJECTIVE To determine the effect of raloxifene therapy on risk of vertebral and nonvertebral fractures. DESIGN The Multiple Outcomes of Raloxifene Evaluation (MORE)(More)
BACKGROUND Previous studies have shown that alendronate can increase bone mineral density (BMD) and prevent radiographically defined (morphometric) vertebral fractures. The Fracture Intervention Trial aimed to investigate the effect of alendronate on the risk of morphometric as well as clinically evident fractures in postmenopausal women with low bone mass.(More)
BACKGROUND A single infusion of intravenous zoledronic acid decreases bone turnover and improves bone density at 12 months in postmenopausal women with osteoporosis. We assessed the effects of annual infusions of zoledronic acid on fracture risk during a 3-year period. METHODS In this double-blind, placebo-controlled trial, 3889 patients (mean age, 73(More)
CONTEXT Alendronate sodium reduces fracture risk in postmenopausal women who have vertebral fractures, but its effects on fracture risk have not been studied for women without vertebral fractures. OBJECTIVE To test the hypothesis that 4 years of alendronate would decrease the risk of clinical and vertebral fractures in women who have low bone mineral(More)
BACKGROUND Many risk factors for hip fractures have been suggested but have not been evaluated in a comprehensive prospective study. METHODS We assessed potential risk factors, including bone mass, in 9516 white women 65 years of age or older who had had no previous hip fracture. We then followed these women at 4-month intervals for an average of 4.1(More)
BACKGROUND Quantitative ultrasound of bone is a new radiation-free technique that measures bone mass and may assess bone quality. Retrospective studies have suggested that low-bone ultrasound of the calcaneus is associated with an increased risk for hip and other fractures in older women. OBJECTIVES To establish the utility of calcaneal quantitative(More)
Falls are a major threat to the health of older persons. We evaluated potential risk factors for falls in 325 community-dwelling persons aged 60 years or older who had fallen during the previous year, then followed up weekly for 1 year to ascertain nonsyncopal falls and their consequences. Risk factors for having a single fall were few and relatively weak,(More)
Based on engineering principles, geometric measurements of femoral size should be related to femoral strength and the risk for hip fracture. To evaluate whether a simple measurement of femoral geometry is associated with hip fracture risk, we obtained dual x-ray absorptiometry scans of the proximal femur on 8074 white women age 67 or older. During an(More)
Women with low bone density in the radius or calcaneus are at increased risk of hip fracture. To see whether bone density of the hip measured by dual X-ray absorptiometry is a better predictor of hip fracture than measurements of other bones, we assessed bone density at several sites in 8134 women aged 65 years or more. 65 women had hip fractures during a(More)
BACKGROUND Parathyroid hormone increases bone strength primarily by stimulating bone formation, whereas antiresorptive drugs reduce bone resorption. We conducted a randomized, double-blind clinical study of parathyroid hormone and alendronate to test the hypothesis that the concurrent administration of the two agents would increase bone density more than(More)
