Linking food and health systems is critical to prevent obesity. The PacDASH intervention will include a food and physical activity (PA) prescription delivered by a physician at a community-based health center (HC), in partnership with farmers' markets (FM) that are based at the HC, and complemented with a toolbox of related activities. The intervention approach supports child food behaviors and social and environmental cues, which are important to making healthy food and PA choices. Linking physicians and health with farmers and food at a convenient HC FM will support increased intake of nutrient-rich, less energy dense foods among children of understudied ethnic groups who are at high risk for obesity.
