This project funding (the School-Based Surveillance Component 1 of CDC-RFA-18-1807) supports the Youth Risk Behavior Survey (YRBS) of public high school students to determine prevalence of risk factors for key health issues affecting adolescents, and the School Health Profiles (SHP) study of school principals and health teachers to determine health related policies and practices. These surveys are conducted in alternate years, with the YRBS in odd-numbered years. The surveys are administered by the Delaware Department of Health and Social Services, Division of Public Health, through its Office of Health Education, which is also responsible for the adult Behavioral Risk Factor Surveillance System (BRFSS). The Division partners with the Center for Drug and Health Studies (CDHS) at the University of Delaware to conduct these surveys. CDHS also provides additional analysis widespread dissemination of the data. Data are used by the Division of Public Health and many of our fellow state agencies, including the Department of Education, the Department of Services to Children, Youth and Their Families, and the Division of Substance Abuse and Mental Health. Many other public, nonprofit and health agencies also use the data to plan, implement and evaluate health programs for Delaware students and their families. The data also are used in public education of policy makers, teachers, health professionals, parents and other groups.
