Purpose: This study evaluated 24-month outcomes of a school-based intensive lifestyle weight management program targeting overweight Mexican-American adolescents. %26lt;br%26gt;Methods: We recruited a total of 71 adolescents (32 males; 45.1%) between the ages of 10 and 14 years, at or above the 85th percentile for body mass index (BMI). Participants were randomized to a 6-month instructor-led intervention (ILI) or a self-help (SH) program. Both interventions were aimed at modifying eating and physical activity behaviors using behavior modification strategies. We assessed changes in participants%26apos; standardized BMI and BMI percentile at baseline, 1, and 2 years. %26lt;br%26gt;Results: Repeated-measures analyses showed that ILI participants showed significantly greater decreases in standardized BMI at 1 and 2 years (F = 8.58, p %26lt; .01; and F = 9.27, p %26lt; .01, respectively) compared with SH controls. Similar results were found for changes in BMI and BMI percentile. At 2 years, the ILI condition decreased their average BMI percentile by 3.9 percentile points, compared to an increase of 1.6 percentile points in the SH condition. %26lt;br%26gt;Conclusions: A school-based intervention resulted in improved weight outcomes in overweight Mexican-American adolescents and results were maintained over 2 years.
