Increased fracture risk has been associated with weight loss in postmenopausal women, but the time course over which this occurs has not been established. The aim of this study was to examine the effects of unintentional weight loss of ≥10 lb (4.5 kg) in postmenopausal women on fracture risk at multiple sites up to 5 years after weight loss.

Context: Several fracture prediction models that combine fractures at different sites into a composite outcome are in current use. However, to the extent individual fracture sites have differing risk factor profiles, model discrimination is impaired.

Objective: The objective of the study was to improve model discrimination by developing a 5-year composite fracture prediction model for fracture sites that display similar risk profiles.

Objective: To examine when, where and how fractures occur in postmenopausal women.

Methods: We analyzed data from the Global Longitudinal Study of Osteoporosis in Women (GLOW), including women aged ≥55 years from the United States of America, Canada, Australia and seven European countries. Women completed questionnaires including fracture data at baseline and years 1, 2 and 3.

Fractures may be associated with higher morbidity in obese postmenopausal women than in nonobese women. We compared health-care utilization, functional status, and health-related quality of life (HRQL) in obese, nonobese, and underweight women with fractures. Information from the GLOW study, started in 2006, was collected at baseline and at 1, 2, and 3 years.

Low body mass index (BMI) is a well-established risk factor for fracture in postmenopausal women. Height and obesity have also been associated with increased fracture risk at some sites. We investigated the relationships of weight, BMI, and height with incident clinical fracture in a practice-based cohort of postmenopausal women participating in the Global Longitudinal study of Osteoporosis in Women (GLOW).

Antiosteoporosis medication (AOM) does not abolish fracture risk, and some individuals experience multiple fractures while on treatment. Therefore, criteria for treatment failure have recently been defined. Using data from the Global Longitudinal Study of Osteoporosis in Women (GLOW), we analyzed risk factors for treatment failure, defined as sustaining two or more fractures while on AOM.

Objectives: To test whether women aged 55 and older with increasing evidence of a frailty phenotype would have greater risk of fractures, disability, and recurrent falls than women who were not frail, across geographic areas (Australia, Europe, and North America) and age groups.

Design: Multinational, longitudinal, observational cohort study.

Setting: Global Longitudinal Study of Osteoporosis in Women (GLOW).

Objectives: Patients with osteoarthritis have increased bone mass but no decrease in fractures. The association between self-reported osteoarthritis and incident falls and fractures was studied in postmenopausal women.

Methods: The Global Longitudinal Study of Osteoporosis in Women is a prospective multinational cohort of 60,393 non-institutionalised women aged ≥55 years who had visited primary care practices within the previous 2 years.

The purposes of this study were to examine fracture risk profiles at specific bone sites, and to understand why model discrimination using clinical risk factors is generally better in hip fracture models than in models that combine hip with other bones. Using 3-year data from the GLOW study (54,229 women with more than 4400 total fractures), we present Cox regression model results for 10 individual fracture sites, for both any and first-time fracture, among women aged ≥55 years. Advanced age is the strongest risk factor in hip (hazard ratio [HR] = 2.

Introduction: Greater awareness of the relationship between co-morbidities and fracture risk may improve fracture-prediction algorithms such as FRAX.

Materials And Methods: We used a large, multinational cohort study (GLOW) to investigate the effect of co-morbidities on fracture risk. Women completed a baseline questionnaire detailing past medical history, including co-morbidity history and fracture.

Purpose: To determine if important geographic differences exist in treatment rates for osteoporosis and whether this variation can be explained by regional variation in risk factors.

Methods: The Global Longitudinal Study of Osteoporosis in Women is an observational study of women ≥55 years sampled from primary care practices in 10 countries. Self-administered questionnaires were used to collect data on patient characteristics, risk factors for fracture, previous fractures, anti-osteoporosis medication, and health status.

Total body mass is a major determinant of bone mass, but studies of the relative contributions of lean mass (LM) and fat mass (FM) to bone mass have yielded conflicting results. This is likely because of the use of bone measures that are not adequately adjusted for body size and, therefore, not appropriate for analyses related to body composition, which is also correlated with body size. We examined the relationship between body composition and peak bone mass in premenopausal women aged 18-30 yr using both size-dependent and size-adjusted measures of bone density and body composition, as well as statistical models adjusted for size-related factors.

Objective: To determine longitudinal patterns and predictors for the utilization of bone mass measurements and anti-osteoporotic medications in the prevention of glucocorticoid-induced osteoporosis.

Methods: Within a managed care population of 7 million persons, we identified 3,125 adult men and women who had initiated longterm glucocorticoid therapy (>or=7.5 mg/day of prednisone equivalent for > 6 mo).

Studies of the management of osteoporosis in older women who have had hip or wrist fractures have found underdiagnosis and undertreatment of the disease. Few such studies have been conducted in the United States, however, and most studies have been confined to a subset of the treatments currently available to treat osteoporosis. Mail surveys were sent to 381 women between 50 and 84 years of age who had been treated for a hip or wrist fracture at a large northeast US teaching hospital between October 1, 1998, and September 30, 2000.

Objectives: This study explored the recognition and treatment of osteoporosis and vertebral fracture among older women by primary care physicians.

Methods: Data from the National Ambulatory Medical Care Survey from 1993 to 1997 were examined for evidence of diagnosis and treatment of osteoporosis or vertebral fracture during visits by White women 60 years and older to primary care physicians.

Results: Fewer than 2% of the women received diagnoses of osteoporosis or vertebral fracture, although expected prevalence is 20% to 30%.
