Estimation of body weight (BW) 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 BW in college women.  Two hundred women were measured for bone widths at the shoulders, hips, elbow, and knee.  Step-wise multiple regression selected knee, hp, and elbow widths in that to predict BW (R = 0.87, SEE = 6.9 kg, CV = 11.0%).  Cross-validation on a separate sample (n = 50) produced a high correlation (r = 0.88) between predicted and actual weight, with 60% of the sample within ±10% of actual weight.  Actual weight tended to be under-predicted to a greater degree in heavier participants (r = -0.76) and those with greater %fat (r = -0.58).  Since heavier women may need more guidance in attaining an ideal weight, further refinement of the current equation seems warranted.
