Abstract

The bioelectrical-impedance-analysis (BIA) method accurately measures body composition in weight-stable subjects. This study validates the use of BIA to measure change in body composition. Twelve obese females underwent weight loss at a mean rate of 1.16 kg/wk. Body composition was measured by deuterium oxide dilution (D₂O), BIA, and skinfold anthropometry (SFA) at baseline and at 5% decrements in weight. Highly significant correlations were obtained between D₂O and BIA (r = 0.971) and between D₂O and SFA (r = 0.932). Overall, BIA predicted change in fat-free mass with greater accuracy (to 0.4 kg) and precision (±1.28 kg) than did anthropometry (to 0.8 kg and ±2.58 kg, respectively). We conclude that BIA is a useful clinical method for measuring change in body composition.
