Decision-Making and the Relationship to Food Intake in Kids
Completed
Conditions studied: Pediatric Obesity
In brief
The purpose of this 18-month project is to investigate how decision-making influences food choice and consumption in children ages 7 to 11 years old. Although several studies suggest that the ability to make good decisions relates to eating behaviors, no studies have looked at how food reward influences the decision-making process to impact actual food intake. This proposal will answer these questions and bridge this gap in knowledge, which could lead to the development of more effective interventions for childhood obesity. To accomplish this, the investigators have assembled a diverse team with expertise in food intake, nutrition, and decision sciences. First, the investigators will establish if there are differences in decision-making between children varying in weight status. Second, the investigators will determine if performance on behavioral decision-making tasks relates to food consumption in the laboratory. Third, the investigators will examine response functional magnetic resonance imaging (fMRI) blood-oxygen-level-dependent (BOLD) response to various rewards (i.e. food and money) and determine if this is influenced by child weight status. Fourth, the investigators will examine differences in fMRI BOLD at rest in decision-making regions are correlated with food intake and weight status. Eighty-two children will participate in our study. The long-term goal of this project is to investigate if there are differences in brain regions corresponding to these behaviors in overweight children and if these differences relate to eating behaviors in this population. Children will undergo fMRI while playing a reward task as well as consume meals in our laboratory. Decision-making will also be assessed by having children complete various behavioral measurements of reward and inhibitory control.
