The purpose of this research study is to evaluate two nutrition and exercise programs in children ages 9-12 who are at risk for developing type 2 diabetes. This study also includes the involvement of parents or guardians who are willing to participate in these programs with the child.

This is a prevention study that evaluates a community-based, family oriented intervention called Reach-Out. The University of Chicago will partner with community organizations including the Women, Infants and Children [WIC] Clinic at the Chicago Department of Public Health Roseland Clinic, South Side YMCA, the Chicago Park District and the Southside Faith-Based Wellness Network of churches to deliver the intervention. Families will be recruited from the high risk population of patients in the University of Chicago Diabetes database and the Chicago Childhood Diabetes Registry; and La Rabida Children's Hospital; and from the broader south side African-American community ("outreach" population). Families will be randomized to behavioral intervention (Reach-Out Program, hands on nutrition and exercise) or control group(Reach-In Program, standard of care consultation).

All who participate in this study will be seen at the University of Chicago GCRC (General Clinical Research Center). They will be asked to come in at the beginning of the study, after 14 weeks, afer 1 year and after 2 years.
