Objectives: To compare event rates for osteoporotic fractures, cardiovascular events, and breast cancer in postmenopausal women with osteoporosis. Design: A prospective, observational study of the placebo group in the double-blind, randomized Multiple Outcomes of Raloxifene Evaluation trial. Setting: One hundred eighty clinical research centers in 25 countries. Participants: Postmenopausal women (n=2,565, mean age=67) with osteoporosis were given calcium (500 mg/d) and vitamin D (400,600 IU/d) supplements. Measurements: The occurrence of at least one new fracture, cardiovascular event, or breast cancer diagnosis at 3 years was identified and adjudicated. Results: The occurrence of any fracture was the most common event in these women. In women without prevalent vertebral fractures (n=1,627), the event rates per 1,000 patient-years were 45.4 for any fracture, 15.2 for vertebral fracture, 4.7 for clinical vertebral fracture, 0.9 for hip fracture, 8.3 for any cardiovascular event, and 5.2 for all breast cancer. In women with prevalent vertebral fractures (n=938), the event rates per 1,000 patient-years were 117.4 for any new fracture, 77.1 for new vertebral fracture, 25.7 for clinical vertebral fracture, 5.8 for hip fracture, 15.1 for any cardiovascular event, and 2.6 for all breast cancer. The effect of prevalent fracture status on event rates was not dependent on whether women were older or younger than 65, but women aged 65 and older had a 3.6 times greater occurrence of cardiovascular events than younger women, irrespective of prevalent fracture status. Conclusion: These data on the relative incidence of clinically significant skeletal and extra-skeletal outcomes may be useful in choosing an agent for health maintenance for postmenopausal women with osteoporosis.

Hyperkyphotic Posture and Risk of Future Osteoporotic Fractures: The Rancho Bernardo Study,

Abstract It is unknown whether kyphosis of the thoracic spine is an independent risk factor for future osteoporotic fractures. In 596 community-dwelling women, we found that with increasing kyphosis, there was a significant trend of increasing fracture risk that was independent of previous history of fractures or BMD. Introduction: It is unknown whether kyphosis of the thoracic spine is an independent risk factor for future osteoporotic fractures. Materials and Methods: We conducted a prospective cohort study of 596 community-dwelling women, 47-92 years of age. Between 1988 and 1991, BMD of the hip and spine and kyphosis were measured. Kyphosis was measured by counting the number of 1.7-cm blocks necessary to place under the occiput so participants could lie flat without neck hyperextension. New fractures were reported over an average follow-up of 4 years. Results: Using a cut-off of at least one block, 18% of the participants had hyperkyphotic posture (range, one to nine blocks). There were 107 women who reported at least one new fracture (hip, spine, wrist, clavicle, shoulder, arm, hand, rib, pelvis, leg, or ankle). In logistic regression analyses, older women with hyperkyphotic posture (defined as at least one block) had a 1.7-fold increased risk of having a future fracture independent of age, prior fracture, and spine or hip BMD (95% CI: 1.00-2.97; p = 0.049). There was a significant trend of increasing fracture risk with increasing number of blocks, with ORs ranging from 1.5 to 2.6 as the number of blocks increased from one to at least three blocks compared with those with zero blocks (trend p = 0.03; models adjusted for age, baseline fracture, spine or hip BMD). Stratification by baseline fracture status and controlling for other possible confounders or past year falls did not change the results. Conclusions: Whereas hyperkyphosis may often result from vertebral fractures, our study findings suggest that hyperkyphotic posture itself may be an important risk factor for future fractures, independent of low BMD or fracture history.

More Broken Bones: A 4-Year Double Cohort Study of Young Girls With and Without Distal Forearm Fractures

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 10 2000

Abstract Predictors of childhood fractures have not been investigated previously. This study was undertaken to determine whether a previous history of forearm fracture, low bone mineral density (BMD; both areal bone mineral density [aBMD, g/cm2] and volumetric bone mineral apparent density [BMAD, g/cm3]), or anthropometry, influence fracture risk in young girls. At baseline, two cohorts of girls, aged 3,15 years, were evaluated: 100 had recently broken a forearm (group 1) and 100 were fracture free (group 2). Four years later we restudied 170 of these girls (82 from group l and 88 from group 2). We now report the relationships of previous fracture history, baseline BMD (measured by dual-energy X-ray absorptiometry), baseline weight, and height to risk of new fracture. More new fractures occurred in group l (37 fractures in 24 girls) than in group 2 (8 fractures in 7 girls; p = 0.0007). The independent predictors for occurrence of a new fracture at any skeletal site in a multivariate model adjusting for age, weight, total body aBMD, and fracture history were previous fracture (hazard ratio [HR], 3.28; 95% CI, 1.41-7.64); age (HR per l-year increase, 0.91; 95% CI, 0.84-0.99); total body aBMD (HR per l SD decrease, 1.92; 95% CI, 1.31-2.81); and body weight (HR per l SD increase, 1.49; 95% CI, 1.06-2.08). Girls with two risk factors together had substantially greater fracture risk: previous fracture and low spinal BMAD (HR, 9.4; 95% CI, 2.8-32.0), previous fracture and high body weight (HR, 10.2; 95% CI, 2.8-37.6), or previous fracture and low total body aBMD (HR, 13.0; 95% CI, 3.9-43.1). We conclude that previous forearm fracture, low total body aBMD, low spinal BMAD, and high body weight each increase risk of new fractures within 4 years in young girls. Interventions to reduce the risk of fractures, particularly forearm fractures, in girls warrant further study. [source]
