The Youth Risk Behavior Surveillance System (YRBSS) is an American biennial survey of adolescent health risk and health protective behaviors such as smoking, drinking, drug use, diet, and physical activity conducted by the Centers for Disease Control and Prevention. It surveys students in grades 9–12. It is one of the major sources of information about these risk behaviors, and is used by federal agencies to track drug use, sexual behavior, and other risk behaviors.
