Ethnic differences in adiposity and body composition: the First Nations bone health study
The purpose of this study was to compare patterns of adiposity and soft tissue composition in First Nations and white Canadian women. A population-based cross-sectional study was performed. A random age-stratified sample of 206 urban First Nations women and 177 white women was recruited. Soft tissue...

Trunk lean tissue was also greater in First Nations women (p = 0.027), but total body lean tissue was similar. The mean trunk adiposity index was strongly related to ethnicity (First Nations +0.5% ± 2.5% versus white –1.7% ± 2.6%, p < 0.0001). Preferential fat accumulation in the trunk of First Nations women persisted after adjustment for body mass, BMI, and other socio-demographic variables (p < 0.0001). First Nations women differ from white women in terms of fat and lean tissue mass and distribution. First Nations women had a preferential increase in trunk fat and this may contribute to high reported rates of diabetes, metabolic syndrome, and cardiovascular events.
