测量了308名和95名18-61岁成年男性的皮褶厚度、体围和体密度。使用308名男性的样本，计算多元回归方程，以估计身体密度，使用皮肤褶皱总和的二次或对数形式，结合年龄，腰围和前臂周长。方程的多重相关性超过0.90，SE约为± 0.001。0.0073 g/ml。回归方程在95名男性的第二个样本上进行交叉验证。预测和实验室测定的体密度之间的相关性超过0.90，SE约为0.0077 g/ml。回归方程适用于不同年龄和肥胖的成年男性。
Skinfold thickness, body circumferences and body density were measured in samples of 308 and 95 adult men ranging in age from 18-61 yr. Using the sample of 308 men, multiple regression equations were calculated to estimate body density using either the quadratic or log form of the sum of skinfolds, in combination with age, waist and forearm circumference. The multiple correlations for the equations exceeded 0.90 with SE of approximately .+-. 0.0073 g/ml. The regression equations were cross validated on the 2nd sample of 95 men. The correlations between predicted and laboratory-determined body density exceeded 0.90 with SE of approximately 0.0077 g/ml. The regression equations were valid for adult men varying in age and fatness.
