Title: Nutrition and Physical Activity Policies, Obesogenic Behaviors and Weight Outcomes
Brief Summary: The investigators long-term goal is to advance the adoption and successful implementation of policies that promote PA and nutrition in after school programs (ASP) nationwide. The investigators objective here is two fold. First, the investigators will test the effectiveness of two promising strategies designed to 1) increase the amount of PA children accumulate while attending an ASP and 2) promote changes in the nutritional quality of the snacks served. This represents a fundamental step in establishing practice-based guidelines (best practices) for the uptake and achievement of public health policy goals (CA and Harvard). Second, the investigators will examine the barriers and facilitators to implementing these strategies. The expected outcome of this study is evidence supporting best practices for ASPs to employ to meet policy goals.
