Study Overview
Brief Summary
The purpose of this center grant is to translate basic behavioral science on habituation theory into clinical intervention using a vertical hierarchical approach from laboratory studies to field studies to the clinical intervention to improve weight loss outcomes in pediatric obesity treatment.
Detailed Description
Habituation is one factor that may be related to excess energy intake. Research has shown that the rate of habituation is inversely related to the amount of food consumed and slower habituation may be a factor that is relevant to obesity, as overweight youth and adults habituate slower and consume more energy than their peers. Habituation is a basic form of learning that is observed in many response systems. We believe that habituation is an important process that mediates food regulation during a meal and across meals. However, there has been no research in children that translates basic research on habituation to food into clinical interventions for pediatric obesity. In the first phase, we will implement a series of laboratory studies to assess the effects of stimulus specificity and variety and the simultaneous reduction of variety for high energy density foods on short (within meal) and long-term (across meal) habituation. The second phase is designed to implement a series of field studies that will extend basic research from the first phase as well as define the optimal interval for reducing variety to facilitate long-term habituation to high energy density foods in the natural environment. The third phase is designed to develop and pilot test a family-based behavioral intervention for children that incorporates findings from phase2 into a clinical intervention.

Arms & Interventions
Variety Group
Traditional family based weight control treatment program with components to reduce variety of high energy dense foods incorporated into the treatment. Families meet weekly for 12 weeks, then by-weekly for 1 month and 1 monthly session for a total of 15 behavioral intervention sessions.
Intervention: Variety Group (Behavioral)
Variety Group
Traditional family based weight control treatment program with components to reduce variety of high energy dense foods incorporated into the treatment. Families meet weekly for 12 weeks, then by-weekly for 1 month and 1 monthly session for a total of 15 behavioral intervention sessions.
Intervention: Nutrition Education Control (Behavioral)
Nutrition Education Control
Traditional family based weight control treatment program, without components from habituation theory incorporated into the treatment. Families meet weekly for 12 weeks, then by-weekly for 1 month and 1 monthly session for a total of 15 behavioral intervention sessions.
Intervention: Nutrition Education Control (Behavioral)
Outcomes
Primary Outcomes
Change of Child Body Composition
Time Frame: Baseline to 6 months
Child percent overweight difference from baseline to 6 month. The formula used to derive weight loss percentage was weight lost at 6 months divided by starting weight, multiplied by 100.
Change Parent Body Composition
Time Frame: Baseline to 6 months
Parent Body Mass Index (kg/m\^2) difference from baseline to 6 months
Secondary Outcomes
- Change in Dietary Intake of Calories(Baseline to 6 months)
- Change in Child Delay Discounting(Baseline to 6 months)
- Change in Parent Delay Discounting(Baseline to 6 months)
- Changes in Variety Measures(Baseline to 6 months)
