测量身高（头臀长），体重，腹部皮下脂肪深度，皮褶厚度的基础上，从13只雌性恒河猴，包括两个年龄组的相关性与体脂肪值来自氚水测定全身水。每项测量与体脂百分比相关的方式随动物年龄的变化而不同。在年轻的，未经生产的女性，顶臀长度是唯一的最好的预测体脂肪，而在老年人，多产的女性，皮褶厚度与体脂肪最高度相关。当所有的测量结果，包括克托莱指数[（wt/ht）2× 1，000]，在统计学上结合起来，并对体脂百分比进行回归分析时，预测能力显著增加。当每个年龄组被单独考虑时，得出的方程再次反映了年龄组的偏见。此外，作为回归方程有效性的内部检查，使用各年龄组选定动物的形态测量数据进行了额外的回归分析。这些公式产生了准确的估计体脂肪相比，从总身体水分的测定。这些分析表明，形态测量数据的预测精度大大提高，通过使用这些测量一致。此外，这种预测的效用受到受试者群体的具体身体特征的影响。
Measurement of height (crown–rump length), body weight, and abdominal subcutaneous fat depth, based on skinfold thickness taken from 13 female rhesus monkeys comprising two age groups were correlated with body fat values derived from tritiated water determinations of total body water. The manner with which each measure was related to percent body fat differed as a function of age of the animal. In the young, nulliparous females, crown–rump length was the single best predictor of body fat, whereas in the older, multiparous females, skinfold thickness correlated most highly with body fat. When all measurements, including the Quetelet index [(wt/ht)2× 1,000], were combined statistically and regressed against percent body fat, a significant increase in predictive ability was obtained. When each age group was considered separately, the resulting equations again reflected the agegroup biases. In addition, as an internal check on the validity of the regression equations, an additional regression analysis was performed using morphometric data from selected animals in each age group. These equations yielded accurate estimates of body fat when compared to determinations made from total body water. These analyses indicate that the predictive accuracy of morphometric data is greatly enhanced by using these measurements in concert. Furthermore, the utility of such predictions is influenced by the specific physical characteristics of the subject population.
