The overall goal of this study is to increase access to and adoption of the Healthy Weight Clinic package in primary care settings serving low income families in the United States who have a disproportionately high prevalence of childhood obesity. Two federally-qualified health centers in Mississippi and two health centers in Massachusetts will be implementing a Healthy Weight Clinic Program. The Healthy Weight Clinic is staffed by a medical provider, a Dietitian/Nutritionist, and a Community Healthy Worker. Patients attend individual medical visits (once per month for 12 months) with the multidisciplinary team, group visits led by a member of the team (once per month for 6 months), and phone follow-up between visits. All patients who receive care at the pilot implementation sites will be exposed to the systems-level intervention. A subset of patients will be invited to participate in a research evaluation of the program.

Inclusion Criteria:

• child is age 2 through 18 years at referral
• child's BMI meets or exceeds the 85th percentile for age and sex
