The purpose of the Youth Risk Behavior Survey (YRBS) is to assist educators and health professionals in determining the prevalence of health-risk behaviors among youth. This report analyzes trends among Native American youth from the Montana YRBS years 2011-2017. Seven sections focus on: (1) Unintentional Injuries and Violence (safety, violence-related behaviors, bullying, and suicide ideation); (2) Tobacco (cigarette smoking, electronic vapor products, and other tobacco products); (3) Alcohol and Other Drugs (alcohol, marijuana, and other drugs); (4) Sexual Behaviors; (5) Dietary Behaviors (body weight, fruit and fruit juices, vegetables, beverages, and breakfast); (6) Physical Inactivity (60 minutes physical activity, screen time, and physical education and sports); and (7) Other Health-Related Topics (dental health, asthma, sleep, grades, indoor tanning devices, and help from resources teachers, speech therapists or other special education teachers). Results compare Native American students to Montana students overall in the YRBS.
