Validation of Skeletal Dimensions to Predict Ideal Body Weight in College Women

Estimation of ideal body weight (IBW) from skeletal dimensions may be helpful in providing guidelines for weight management. The purpose of this study was to evaluate the accuracy of bone widths to estimate IBW in college women. College women (n = 1601) were measured for bone widths at the shoulders, hips, elbow, and knee. Step-wise multiple regression in a healthy percent fat range (%fat = 20-30%) selected knee, hip, and shoulder widths to predict IBW (R = 0.65, SEE = 6.1 kg, CD = 9.9%). Cross-validation on a separate sample (n = 141) found the difference between predicted and actual weight was significantly greater for heavier participants (-10.5 kg) than for ideal (1.5 kg) and underweight (6.4 kg) participants. These findings suggest that underweight women could gain on average 6.4 kg, largely composed of muscle mass, while overweight women could lose on average 10.5 kg largely composed of fat.
