Childhood obesity and related long term effects are serious public health problems, but not all children do well in obesity treatment. In collaboration with Dr. Ellen Schur at the University of Washington, the Roth lab is testing a new theory that the brain does not appropriately suppress appetite after a meal in obese children through the use of functional neuroimaging. In conjunction with Drs. Elizabeth Aylward (CIBR), Brian Saelens (Center on Child Health, Behavior, and Development), and Thomas Grabowski (Department of Radiology, UW), we are also testing if this brain function affects children’s response to obesity treatment. Based on the results, future studies will refine treatment procedures, developing and testing alternate strategies for obesity treatment in children.
