Clinical Trial Summary

The objective of the study is to compare children at low risk for obesity (two healthy weight parents) to children at high risk for obesity (two overweight parents) in their response rate to food taste and in their rate of learning using fMRI.

Description:

The primary aim of this project is to conduct an adequately powered study that compares children at low risk for obesity to children at high risk for obesity on their brain responses to food tastes during a pavlovian learning task. Seven assessment visits will be conducted at three separate time points; baseline, 1-year follow up, and 2-year follow up. Assessments will include anthropometry, interviews, computer tasks, questionnaires, and an fMRI scan. This program of research tests a novel hypothesis regarding overeating and the development of obesity in children, and could provide critical data on individual vulnerabilities to overeating for further research. Furthermore, this study could provide mechanisms for intervention with regards to cue-reward learning in children, to ultimately prevent obesity in youth.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cue-reward learning	Whether rate of the shift in BOLD response from food cue to neutral cue is different between high and low-risk children	Baseline only
Primary	Reward Sensitivity	Whether the BOLD response to food cue differs between high and low-risk children	Baseline only
Primary	Weight gain	Whether rate of cue reward and reward sensitivity predict weight gain	Change from baseline at an average of 12 months and 24 months
