Objective: To assess the 1-year results of a multidisciplinary, cognitive behavioral therapy treatment program for overweight and obese children.
Study design: Children (n = 73; 8 to 15 years old) participated in a prospective study aimed at reduction of the body mass index-standard deviation score (BMI-SDS), adapting a healthy lifestyle and creating a positive self-image and higher self-esteem, by use of a group approach and parental involvement. Reduction in BMI-SDS and percent overweight were measured and analyzed by use of MIXED modeling.
Results: The participants achieved a 0.6 BMI-SDS reduction, comparable to a weight loss of 18.7% after 1 year (P < .0001). The proportion of dropouts was 33%. Compared with the follow-up group, dropouts were older, increased in BMI-SDS before start of treatment, and were less successful in BMI-SDS reduction during treatment.
Conclusions: This treatment program had a positive effect on BMI-SDS in overweight and obese children at 1-year follow-up. Differences between the characteristics of the dropout and follow-up group may reflect predictor variables for treatment outcome.
