Weight Management for Adolescents With IDD

Rates of obesity and obesity related chronic health conditions are higher in adolescents with Intellectual and Developmental Disabilities (IDD) than those in the general population. Many of the negative health consequences observed in obese adults are already present in obese adolescents with IDD. This study is a 3 group randomized trial to evaluate the intervention delivery system and type of reduced energy diet. The investigators will randomize 123 overweight/obese adolescents with mild to moderate IDD to one of 3 groups for an 18 month trial (6 month weight loss; 12 month weight maintenance): group 1) Face-To-Face/CD group 2) Technology delivery/CD group 3) Technology delivery/eSLD. All participants will receive a progressive program of physical activity. Participants on the CD diet will be asked to consume a nutritionally balanced, reduced energy, high volume, lower fat ( fat=20-30% energy) diet. Participants on the eSLD will consume pre-packaged portion controlled meals with the addition of 5 fruits and vegetables per day. FTF will meet with a health educator and will track progress using pen and paper records for both physical activity and diet. TECH groups will receive the intervention using an iPad with the FaceTimeTM application for video meetings with a health educator and will track progress using the Lose it! application for both physical activity and diet.
