This study examined trends in the percentage of US secondary schools that engaged in practices related to violence prevention (eg,…

Background: Adverse Childhood Experiences (ACEs) can impair health and other outcomes. To obtain district-level data about the prevalence and impact of ACEs in Chicago Public Schools (CPS), we advocated for CPS to add a short ACE screener to the 2017 Youth Risk Behavior Survey (YRBS) and analyzed the results. Methods: Responses to the screener…

We explored a variety of health risks jointly to identify distinct patterns of risk behaviors among adolescents. Methods: Latent class models were estimated using Youth Risk Behavior Surveillance System…

Background: Teen dating violence (TDV) negatively impacts health, mental and physical well-being, and school performance.
