Body density of 170 young women was experimentally determined by water displacement technique. A set of 44 body measurements of each subject was taken using standard methods. A stepwise multiple linear regression technique was employed and several regression equations were constructed which predicted body density, percent body fat and lean body mass from different combinations of body measurements. The best prediction equation (R = 0.84) for body density included thigh and iliac crest girths, chest skinfold thickness and biiliac diameter. The highest multiple correlation (R = 0.81) to predict lean body mass was obtained by the use of stature, body weight, iliac crest girth and chest skinfold thickness. The derived regression equations were validated on a separate test group of 50 women.The validity correlations ranged from 0.84 to 0.91 in the case of body density, percent body fat and lean body mass.
