To investigate the prevalence and incidence of clinical fractures in obese, postmenopausal women enrolled in the Global Longitudinal study of Osteoporosis in Women (GLOW). This was a multinational, prospective, observational, population-based study carried out by 723 physician practices at 17 sites in 10 countries. A total of 60,393 women aged ≥55 years were included. Data were collected using self-administered questionnaires that covered domains that included patient characteristics, fracture history, risk factors for fracture, and anti-osteoporosis medications. Body mass index (BMI) and fracture history were available at baseline, 1 and 2 years in 44,534 women, 23.4% of whom were obese (BMI ≥30 kg/m2). Fracture prevalence in obese women at baseline was 222 per 1,000 and incidence at 2 years was 61.7 per 1,000, similar to rates in non-obese women (227 and 66.0 per 1,000, respectively). Fractures in obese women accounted for 23% and 22% of all previous and incident fractures, respectively. The risk of incident ankle and upper leg fractures was significantly higher in obese than in non-obese women whilst the risk of wrist fracture was significantly lower. Obese women with fracture were more likely to have experienced early menopause and to report two or more falls in the past year. Self-reported asthma, emphysema, and type 1 diabetes were all significantly more common in obese than non-obese women with incident fracture. At 2 years, 27% of obese women with incident fracture were receiving bone-protective therapy, compared with 41% of non-obese and 57% of underweight women. Our results demonstrate that obesity is not protective against fracture in postmenopausal women and is associated with increased risk of ankle and upper leg fractures. These findings have major public health implications in view of the rapidly rising incidence of obesity. Further studies are required to establish the pathogenesis of fractures in the obese population and to develop effective preventive strategies.
