The Montana Youth Risk Behavior Survey (YRBS) assists educators and health professionals in determining the prevalence of health-risk behaviors as self-reported by Montana youth. Initiated by the Centers for Disease Control and Prevention (CDC) in 1988, the YRBS aims to identify the leading causes of mortality, morbidity, and social problems among youth. This report analyzes trends among Native American youth from the Montana YRBS years 2011-2019. Seven data tables focus on: (1) Unintentional Injuries and Violence; (2) Tobacco Use; (3) Alcohol and Other Drugs; (4) Sexual Behaviors; (5) Dietary Behaviors; (6) Physical Inactivity; and (7) Other Health-Related Topics.
