Clinical Trial Summary

The purpose of this study is to determine if a family based diet and exercise program is helpful for extremely overweight children aged 8-12, and to compare this approach to standard medical management of severe pediatric obesity.

Description:

The prevalence of pediatric obesity has increased significantly, and approximately 11% of American children and adolescents are obese. Of particular concern, the greatest increase in prevalence has occured among the heaviest children. Severe pediatric obesity (defined as > 150% of ideal body weight for height) is associated with higher rates of medical and psychosocial morbidity than milder obesity is. Moreover, severely obese children are likelier than less severely obese children are to become obese adults and suffer the long-term health consequences of obesity. Although the efficacy of family-based behavioral weight control programs in the treatment of moderate pediatric obesity is well established, few studies have focused on the treatment of severe obesity. Thus in this application, we propose a randomized controlled trial to evaluate the efficacy of a family-based behavioral weight control program in the management of severe pediatric obesity.

Two hundred children aged 8-12 will be randomized to a six-month family-based program or usual care, and will complete assessments at pre- and post- treatment and 6-month and 12-month follow-ups. We hypothesized that: 1) Children who participate in the family-based program, when compared to children who receive usual care, will show favorable changes in body mass index, body composition, food intake, activity level, and cardiovascular risk factors. 2) Children who participate in the family-based program, when compared to children who receive usual care, will report higher levels of self-esteem, social competence and health-related quality of life, and report fewer psychiatric symptoms. A secondary aim of the the proposed investigation is to examine the relationships among gender, race, compliance to diet and exercise. level of parent adherence and treatment outcome. The proposed investigation is significant as the first effort to systematically evaluate a treatment program for severely obese children. It will provide data about a serious public health problem and establish a foundation for programmatic research to develop effective treatments for an underserved population.
