The proposed study will increase knowledge about the role of street vendors in the after-school eating environment among elementary and middle school children in low-income neighborhoods. The overall aim is to examine whether mobile vendors are a feasible vehicle for the sales of fresh fruits, vegetables and healthy snacks, and to evaluate a community-based quasi-experimental intervention aimed at improving the overall nutritional quality of children’s food purchases. The target population of this study is urban, primarily Latino, elementary- and middle-school age children and young adolescents.
