Centers for Disease Control and Prevention, June 10, 2016

The CDC has released the report: Youth Risk Behavior Surveillance —  United States 2015.

The Youth Risk Behavior Surveillance System monitors six categories of priority health behaviors among youth and young adults: 1) behaviors that contribute to unintentional injuries and violence; 2) tobacco use; 3) alcohol and other drug use; 4) sexual behaviors related to unintended pregnancy and sexually transmitted infections (STIs), including human immunodeficiency virus (HIV) infection; 5) unhealthy dietary behaviors; and 6) physical inactivity.
A national school-based Youth Risk Behavior Survey (YRBS) is conducted by CDC and  by state and local education and health agencies. This report summarizes results for 118 health behaviors from surveys conducted among students in grades 9–12.
