Changes in body composition during weight loss among obese adolescents are poorly understood. This study characterized the composition of weight loss, and its association with changes in waist circumference (WC) in obese adolescents. Total (Tot), trunk (Tr) and appendicular (Ap) fat mass (FM) and lean mass (LM) were measured by dual-energy X-ray absorptiometry (DXA) in 61 obese adolescents (40 girls) who participated in a randomized-controlled weight-loss trial. Changes in body composition were assessed at 0, 6, and 12 months using mixed-effects regression models. Correlation analysis of change in WC and total and regional compartments of FM and LM were also assessed. Weight-loss for adolescents was 90.3% FM and 15.9% LM at 0–6mo, and 98.2% FM and 7% LM at 0–12 mo. At 12mo, girls lost 2.67 kg more TotFM than boys in models adjusted for height, age, race, and baseline weight. Boys gained LM in all compartments in all models. At 12mo, girls lost TotLM (2.23 ±0.74, p<0.004) and ApLM (0.69 ±0.31, p=0.03), and gained TrLM (0.37±0.35, p=0.29). The percentage LM, increased for boys and girls in all models. TotFM was correlated with BMI change with TotFM (R=0.70–0.91, p=0.001) and WC change (R=0.53–0.55, p<0.001). Weight loss in obese adolescents during a weight-loss trial using lifestyle management and sibutramine was primarily from trunk fat mass. Although absolute LM increased in boys and decreased in girls, the percentage of weight that is LM increased for both boys and girls. Changes in BMI were more reflective of changes in FM than changes in WC.
