Summary Objective: To evaluate predictors for intervention dropout and successful reduction of metabolic syndrome risk factors among obese children enrolled in a short-term, clinic-based weight-loss intervention. Design, setting, subjects: Retrospective database review of 1080 children 8 months to 17 years. seen a pediatric obesity clinic. Interventions: Behavior modification counseling to induce change in dietary and exercise choices. Main outcome measures: (1) Pre-/post-intervention change in body mass index (BMI), waist circumference, blood pressure, glucose, insulin, and cholesterol (LDL, HDL, & total). (2) Predictors of successful decrease in BMI and clinic drop-out. Analysis: Paired t-tests for pre-/post-intervention comparisons. Linear regression to assess predictors of success and predictors of drop-out, with adjustment for age, gender, race, insurance status, and service area.

Results: Among children evaluated, adolescent females were most likely to achieve successful decrease in BMI, insulin level, and LDL cholesterol post-intervention. Nearly 40% of children dropped out early in the intervention. Predictors of drop out included age
