Definition: The Youth Risk Behavior Surveillance System (YRBSS) is a school-based survey system developed by the U.S. Centers for Disease Control and Prevention (CDC) to monitor priority health-risk behaviors that contribute to the leading causes of death and disability among youth and young adults in the United States.
The YRBSS comprises a national school-based survey conducted by the CDC and separate state, territorial, tribal, and local school-based surveys conducted by education and health agencies. This biennial (every two years) surveillance system collects data on six categories of health-risk behaviors among high school students (grades 9-12), and sometimes middle school students: behaviors that contribute to unintentional injuries and violence, sexual behaviors, alcohol and other drug use, tobacco use, unhealthy dietary behaviors, and inadequate physical activity. The data are collected through self-administered questionnaires completed anonymously by students in classrooms.
The importance of YRBSS in public health is profound, as it provides critical data used by public health officials, educators, policymakers, and researchers to understand the prevalence and trends of risk behaviors among youth. This information is instrumental in developing, implementing, and evaluating school health programs and policies designed to prevent these behaviors and improve adolescent health. By identifying demographic disparities and changes over time, YRBSS data enable targeted interventions, resource allocation, and evidence-based decision-making to promote the well-being and healthy development of young people across the nation.
Key Context:
- CDC Surveillance System: A primary tool managed by the CDC for monitoring adolescent health behaviors nationwide.
- Biennial Data Collection: Conducted every two years, allowing for robust trend analysis over time.
- Focus on Leading Risk Behaviors: Concentrates on behaviors directly linked to major causes of morbidity and mortality in youth.
