Mobile Integrated Care for Childhood Obesity

The goal of this clinical trial is to evaluate a new way of providing healthcare to children with an unhealthy weight. Families who participate will be assigned by chance to one of two groups. One group will see their child's primary care provider to talk about healthy lifestyles for 6 months. The other group will be in our Healthy Lifestyle program for 6 months. This will include: * Check-ins with lifestyle specialists and community health workers, * A mobile app to help support a healthy lifestyle, and * Access to community programs and activities. The main questions the study aims to answer are: * Do children in the Healthy Lifestyle program have better weight outcomes? * Do more families in the Healthy Lifestyle program stay in the study? * Does the Healthy Lifestyle program work better for families from certain communities?
