While sex and drug use are on the decline among teenagers in the United States, other health risks — including suicidal ideation and bullying — do not appear to be subsiding, and experts are concerned.

That’s according to a new National Youth Risk Behavior Survey report, released by the US Centers for Disease Control and Prevention on Thursday.

The report provides data from 2007 to 2017, detailing trends in sexual behavior, high-risk substance use, violence victimization, as well as mental health and suicide among public and private high school students.

“Overall, I think youth are making better decisions, particularly about their sexual behavior and their drug use,” said Kathleen Ethier, director of the CDC’s Division of Adolescent and School Health in the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, who was an author of the report.
