The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-risk behaviors, plus obesity and asthma, among adolescents at the national, state, territorial, tribal, and local levels.

The Data Summary & Trends Report pdf icon[PDF – 31 MB] uses YRBS data to focus on four priority focus areas associated with STDs, including HIV, and unintended teen pregnancy: Sexual Behaviors, High-Risk Substance Use, Experiencing Violence, and Mental Health and Suicide.

Youth Online allows users to access YRBSS data, perform statistical tests, and create customized tables, maps, and graphs. The YRBS Explorer provides YRBSS data in pre-created tables and graphs, allowing users to examine national, state, and local data without conducting analyses. The YRBS Analysis Tool allows users to run a real-time data analysis that generates frequencies, cross tabulations, and stratified results.
