BMD at multiple sites and risk of fracture of multiple types: Long-term results from the study of osteoporotic fractures

In a large cohort of U.S. women aged 65 and older, we report the relationships of BMD measured at several sites, and subsequent fracture risk at multiple sites over >8 years of follow-up. Although we found almost all fracture types to be related to low BMD, the overall proportion of fractures attributable to low BMD is modest.
