Afterschool Rx 2.0: Prescriptions to Afterschool Care for Pediatric Cardiovascular Risk Reduction

The goal of this clinical trial is to learn if "prescribing" afterschool care to children at risk for poor heart health later in life increases their physical activity and improves their heart health. 'Prescriptions' will be provided by pediatricians at participating Federally Qualified Health Centers and vouchers to existing afterschool programs (e.g., YMCA, Boys and Girls Clubs) will be provided by the research study. The main questions this study aims to answer are: Can afterschool care providers and health care providers easily offer and keep using the voucher program? Will families use the voucher? Do they go to afterschool care regularly, and do the families who use them represent a wide range or backgrounds? Does going to afterschool care help children be more physical activity? Does going to afterschool care improve heart health? Researchers will compare two randomly assigned time periods; one semester when families get the voucher and one semester where they do not. They will look at whether use of the afterschool care voucher leads to more physical activity and improved heart health.
