Ethnic differences in body composition and their relation to health and disease in women

Differences in body composition between black and white women have been well established. Black women have more bone and muscle mass, but less fat, as a percentage of body weight, than white women, after controlling for ethnic differences in age, body weight, and height. In addition, black women have more upper-body fat than white women. These ethnic differences in body composition appear to be associated with disease risk in women. The greater skeletal and muscle mass in black compared to white women appears to protect them from osteoporosis. The relationship between fat distribution and cardiovascular disease also appears to be influenced by ethnicity. This review has two purposes: (1) To examine previous research investigating ethnic differences in body composition between black and white women; and (2) To demonstrate the relationship between body composition and disease in women as a function of ethnicity.
