To determine the relationship between measures of body size and the risk of hip fracture in elderly women.
The association between measures of body size and hip fracture risk was assessed in 8,011 ambulatory, nonblack women 65 years of age or older enrolled in the Study of Osteoporotic Fractures with measurements of total body weight, percent weight change since age 25, hip girth, lean mass, fat mass, percent body fat, body mass index, modified body mass index, and femoral neck bone mineral density (BMD) at the second examination.
These 8,011 women were followed prospectively for incident hip fractures occurring after the second examination, which were confirmed by review of x-ray films.
During an average of 5.2 years after the second examination, 236 (2.9%) women experienced hip fractures.
Similar associations were observed between hip fracture risk and all measures of body size including total body weight, percent weight change since age 25, hip girth, lean mass, fat mass, percent body fat, body mass index, and modified body mass index.
Women with smaller body size had a higher risk of subsequent hip fracture compared with those with larger body size, while women with average and larger body sizes shared similarly lower risks of subsequent hip fracture.
For example, the incidence rate of hip fracture was 9.35 per 1000 woman-years in women in the lowest quartile of total weight compared with 4. (...)
