Correlation coefficients among the various commonly used indices of body mass and measures of skinfold thickness were calculated using 16,459 adult Black of white samples derived from the data sets of the US Health and Nutritional Examination Survey I of 1971 to 1974. Compared to weight and weight-height cube ratio, weight-height square ratio, and weight-heightp ratio exhibit the highest correlation with skinfold thickness. Furthermore, weight-height square ratio and weight-heightp ratio showed the same amount of correlation with skinfolds. Therefore, weight-heightp ratio is not the best indicator of adiposity. It is concluded that weight-height square ratio along with measures of subcutaneous fat such as skinfold thickness would provide adequate information about body size and body fatness. The applicability of weight-heightp is limited to studies concerned with interpopulation comparisons of body mass and where there are differences in height.
利用1971年至1974年美国第一次健康与营养检查调查数据集里的16459名成年黑人和白人样本，计算了各种常用体重指数与皮褶厚度测量值之间的相关系数。与体重、体重-身高立方比相比，体重-身高平方比和体重-身高p比与皮褶厚度的相关性最高。此外，体重-身高平方比和体重-身高p比与皮褶的相关性相同。因此，体重-身高p比不是肥胖的最佳指标。得出的结论是，体重-身高平方比与皮下脂肪测量值（如皮褶厚度）一起，将提供有关身体大小和身体脂肪的充分信息。体重-身高p比的适用性仅限于有关人群间体重比较以及身高存在差异的研究。
