Washington: A new study has shown that postmenopausal obese women are almost as likely to fracture as non-obese women, and that poor mobility and increased risk of falls may play an important role. Obesity is widely believed to be protective against fracture, but the study documented a high prevalence of obesity in postmenopausal women with fragility fracture. The study compared prevalence and location of fractures in obese and non-obese postmenopausal women and examined specific risk factors for fracture. A history of fracture after age 45 years was observed in 23 percent of obese and 24 percent of non-obese women. Nearly one in four postmenopausal women with fractures is obese.
