U.S. adolescents reduce risky behaviors, increase depression symptoms

A new study shows that U.S. adolescents have become less involved in risky behaviors since 1999. These behaviors include substance use, violence, and unsafe sexual practices. More teenagers are now reporting lower levels of these risky actions and fewer signs of mental health issues. The research was published online on March 18 and will appear in the April 2025 issue of Pediatrics. It analyzed data from over 178,000 students in grades 9-12 across the nation. The study was conducted by researchers from Boston College and San Diego State University. Despite the positive trends, a small but growing number of adolescents are experiencing symptoms of depression. This group, which represents less than 9% of those surveyed, has increased feelings of hopelessness and suicidality. This indicates a need for more public health efforts to address these mental health concerns. Coley, the lead researcher, emphasized the importance of focusing on the larger group of youth who are avoiding risky behaviors. She noted that while most teens are doing well, the increasing signs of depression among some groups must not be overlooked. This information is crucial for policymakers and health professionals aiming to improve the mental well-being of adolescents in the U.S.
