The relationship of skinfold thicknesses to body density and of skinfold thicknesses to densitometrically determined body fat was evaluated in a group of 378 boys and girls, aged 7-20 years. According to their maturation level, they were divided into a prepubertal, a pubertal and a post-pubertal group. In each maturation group boys were older, had higher body-weights and body heights, higher body densities, lower percentage body fat, higher waist:hips ratios and higher trunk:total skinfolds ratios than girls. Body density in each maturation level could be quite precisely predicted by skinfold thicknesses. In prepubertal and pubertal boys and girls but not in post-pubertal boys and girls, age was also an important predicting variable for body density. The assessment of percentage body fat from skinfold thicknesses had a prediction error of 3-5%, which was highest in the prepubertal children. The prediction error is comparable to the prediction error of percentage body fat from skinfold thicknesses in adults, as reported in the literature. Only in post-pubertal boys and girls was the waist:hip ratio correlated with measures of body fatness. Moreover, only in the post-pubertal boys and in the pubertal and post-pubertal girls was the waist:hips ratio correlated with another measure of body fat distribution, the trunk:total skinfold ratio. The relative amount of internal body fat was found to be higher in the younger maturation groups. It is concluded that at younger ages the waist:hips ratio is a poor indicator of body fat distribution.
在一组378名7至20岁的男孩和女孩中，评估了皮褶厚度与身体密度的关系以及皮褶厚度与通过密度测定法确定的身体脂肪的关系。根据他们的成熟水平，将他们分为青春期前、青春期和青春期后组。在每个成熟组中，男孩比女孩年龄更大、体重和身高更高、身体密度更高、体脂百分比更低、腰臀比更高以及躯干与总皮褶厚度比更高。每个成熟水平的身体密度都可以通过皮褶厚度相当精确地预测。在青春期前和青春期的男孩和女孩中，但在青春期后的男孩和女孩中并非如此，年龄也是身体密度的一个重要预测变量。根据皮褶厚度评估体脂百分比的预测误差为3%至5%，这在青春期前儿童中最高。该预测误差与文献报道的成年人根据皮褶厚度评估体脂百分比的预测误差相当。只有在青春期后的男孩和女孩中，腰臀比与身体脂肪量的测量值相关。此外，只有在青春期后的男孩以及青春期和青春期后的女孩中，腰臀比与身体脂肪分布的另一个测量值，即躯干与总皮褶厚度比相关。发现较年轻成熟组的体内脂肪相对量更高。得出的结论是，在较年轻的年龄段，腰臀比是身体脂肪分布的一个较差指标。
