INTRODUCTION
The epidemiologic literature has consistently shown that black women and men have a higher bone mineral density (BMD) and a lower incidence of osteoporotic fracture compared to age- and sex-matched whites. The lower rate of fractures among blacks has been attributed to their higher BMD levels, but other factors could contribute. Furthermore, the relationship between BMD and fractures may not be the same for different racial groups. Older Gambian women experience a low rate of osteoporotic fracture despite low bone mineral content. Regardless of the exact magnitude of the association between BMD and osteoporotic fracture, it is well-established from studies, such as NHANES III, that BMD is higher in African Americans than Caucasian Americans and that the rates of osteoporosis and osteopenia are lower.
