UCSD and Rady Children's Hospital are conducting two no-cost weight control research programs, iROC and FRESH, for overweight children ages 8-12 years old and their families. If you're worried about your child's weight, or if your child continues to snack or eat after a full meal and says he/she is always hungry, you may qualify for one of two studies.
