Fat patterning was studied in a sample of 76 obese women before and after weight reduction by principal components analysis. Circumferences were selected as variables rather than skinfolds because circumferences correlated more highly with body composition determined either by total body water or total body potassium. A separate sample of 136 males and females, measured once, was employed to validate the results. The validation sample yielded similar findings. Two significant components were found, the first contrasting upper and lower fatness and the second trunk and extremity fatness. Waist circumference was the best predictor of upper-body fat patterning. For the lower body, thigh circumference loaded more highly than did the iliac crest circumference. Arm circumference did not contribute significantly to upper-lower fat patterning.
通过主成分分析对76名肥胖女性在减重前后的脂肪分布模式进行了研究。选择周长作为变量而非皮褶厚度，因为周长与通过总体水或总体钾测定的身体成分的相关性更高。使用一个由136名男性和女性组成的单独样本进行了一次测量，以验证结果。验证样本得出了相似的结果。发现了两个显著成分，第一个成分对比上身和下身的肥胖程度，第二个成分对比躯干和四肢的肥胖程度。腰围是上身脂肪分布模式的最佳预测指标。对于下半身，大腿围的负荷比髂嵴围更高。上臂围对上下身脂肪分布模式没有显著贡献。
