The Centers for Disease Control and Prevention (CDC) released results from the 2011 Youth Risk Behavior Surveillance Survey (YRBSS/YRBS). This survey is used to track youth–risk behavior trends throughout the nation, every other year in odd years, ever since 1991. Overall, most unhealthy, high-risk behaviors have been trending downward since 1991, but some risk behaviors increased slightly in 2011. Access the full CDC report for details, and note that summaries are contained at the beginning of the report, while data tables are located near the end.
