身体质量指数(BMI)是最常用的肥胖测量指标，最近，一些研究人员主张直接测量肥胖程度，而不是使用BMI。这项研究是为了确定体重指数对生活在不同环境中的三个西非血统人群的体脂水平的预测能力。1994年至1995年期间，尼日利亚、牙买加和美国共有1054名黑人男性和女性接受了检查。使用标准化方案测量所有部位的身高、体重、腰围和臀围，以及血压；使用生物电阻抗分析估计体脂百分比。体脂百分比和BMI在不同部位和性别的人群中高度相关，其结果r(2)在0.61到0.85之间。这种关系在所有人群中都是二次方的，除了尼日利亚男性，他们的关系是线性的。不同地点的回归系数相似，但截距估计的平均体脂水平有显著差异(p<；0.001)，这使得地点间比较困难。与BMI相比，体脂百分比并不能更好地预测血压、腰围或臀围。
Body mass index (BMI) is the most commonly used measure of obesity, Recently, some investigators have advocated direct measurement of adiposity rather than use of the BMI. This study was undertaken to determine the ability of BMI to predict body fat levels in three populations of West African heritage living in different environments. A total of 1,054 black men and women were examined in Nigeria, Jamaica, and the United States during 1994 and 1995. A standardized protocol was used to measure height, weight, waist and hip circumferences, and blood pressure at all sites; percentage of body fat was estimated using bioelectrical impedance analysis. Percentage of body fat and BMI were highly correlated within site- and sex-specific groups, and the resulting r(2) 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.
