Abstract
Determines the ability of BMI to predict body fat levels in three populations of West Africa heritage living in different environments. Examines 1,054 black men and women in Nigeria, Jamaica, and the United States during 1994 and 1995. Uses a standardized protocol to measure height, weight, waist and hip circumferences, and blood pressure at all sites and estimates percentage of body fat using bioelectrical impedance analysis. Percentage of body fat and BMI were highly correlated within site- and sex-specific groups, and the resulting r2 ranged from 0.61 to 0.85. The relation was quadratic in all groups except Nigerian men, in whom it was linear. The regression coefficients were similar across sites, yet the mean body fat levels differed significantly (p 0.001) as estimated by the intercept, making intersite comparison difficult. Compared with BMI, percentage of body fat was not a better predictor of blood pressure or waist or hip circumference.....
