Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Variety Group

Intervention Type BEHAVIORAL

The intervention will consist of our traditional family based weight control intervention with elements of reducing variety of high energy dense foods for the variety group.

Nutrition Education Control

Intervention Type BEHAVIORAL

The intervention will consist of our traditional family based weight control intervention.

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.
