Body-fat distribution and changes in the atherogenic risk-factor profile in obese adolescent girls during weight...

We examined the effect of the pattern of body-fat distribution on the modification of atherogenic risk factors in obese adolescent girls during weight reduction. During the 6-wk program, which included a mixed diet of 4321 kJ/d and intensive physical exercise, the girls lost 8.5 +/- 2.4 kg and their waist-to-hip ratio (WHR) decreased from 0.86 +/- 0.05 to 0.81 +/- 0.05 (P < 0.01). Significant reductions were observed for total cholesterol, LDL cholesterol, uric acid, fasting insulin, and systolic and diastolic blood pressure. Girls with abdominal obesity (WHR > 0.88) had greater reductions in serum cholesterol, LDL cholesterol, and uric acid than did girls with gluteal-femoral obesity (WHR < 0.81). In a multivariate-regression analysis these differences could be partly explained by the greater weight loss of the girls with abdominal obesity. These results suggest that during weight reduction girls with abdominal obesity exhibit more beneficial changes in the atherogenic-risk-factor profile than do girls with gluteal-femoral obesity, partly because of a greater weight loss.
