IDDAdol: Weight Management for Adolescents With IDD
Study Details
Study Description
Brief Summary
The goal of this study is to explore the impact of two different diets (conventional vs. enhanced stop light) and two different delivery systems (face-to-face vs. remote) on weight across 18 months in overweight and obese adolescents with intellectual and developmental disabilities.

Detailed Description
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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Face-To-Face/CD Delivery: Face-to-face Diet: Conventional diet |
Dietary Supplement: Conventional Diet (CD)
CD is a nutritionally balanced, reduced energy, high volume, lower fat ( fat=20-30% energy) diet.
Behavioral: Face-to-face (FTF)
FTF will meet with a health educator in person and will track progress using pen and paper records for both physical activity and diet.
|
| Experimental: Technology delivery/CD Delivery: Technology Diet: Conventional diet |
Dietary Supplement: Conventional Diet (CD)
CD is a nutritionally balanced, reduced energy, high volume, lower fat ( fat=20-30% energy) diet.
Behavioral: Technology (TECH)
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.
Other: iPad with FaceTime
TECH groups will receive the intervention using an iPad with the FaceTimeTM to the intervention field.
|
| Experimental: Technology delivery/eSLD Delivery: Technology Diet: enhanced Stop Light Diet |
Dietary Supplement: Enhanced Stop Light Diet (eSLD)
eSDL includes reduced energy portion controlled meals for 6 months, encouraged consumption of lower energy shakes and 35 fruits and vegetables per week.
Behavioral: Technology (TECH)
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.
Other: iPad with FaceTime
TECH groups will receive the intervention using an iPad with the FaceTimeTM to the intervention field.

Outcome Measures
Primary Outcome Measures
- Weight loss between groups randomized to FTF/CD, TECH/CD and TECH/eSLD [Change in weight from baseline to 6 months]
Participants will be weighed in shorts and a t-shirt between 7 and 10 AM, in duplicate, on a calibrated scale to the nearest 0.1 kg.
Secondary Outcome Measures
- Weight change between groups randomized to FTF/CD, TECH/CD, or TECH/eSLD [Change in weight from baseline to 18 months]
Participants will be weighed in shorts and a t-shirt between 7 and 10 AM, in duplicate, on a calibrated scale to the nearest 0.1 kg.
- Cost of the intervention delivery [Accumulated cost of the intervention delivery from baseline to 18 months]
