Brain and Behavior Influences on Obesity Development From Infancy Through Childhood
Recruiting
The investigators project, RESONATE, aims to investigate why some children develop obesity. To do this it uses data on eating and eating-related behaviors, genetic and environmental factors, and brain structure and function. This data is collected in a sub-sample of RESONANCE, a large study of families of children from infancy through childhood. The results will lay foundations for the development of early interventions to prevent or treat obesity.
