The Montana Youth Risk Behavior Survey (YRBS) is administered by the Montana Office of Public Instruction every two years to students in grades 7 through 12. The purpose of the survey is to help monitor the prevalence of behaviors that not only influence youth health, but also put youth at risk for the most significant health and social problems that can occur during adolescence. While all schools in Montana can participate in the survey on a volunteer basis, approximately 50 high schools are randomly selected to be included to provide the Montana statewide data to be used in other national YRBS reports. The 2017 YRBS was conducted in February 2017. For the purpose of this report, youth that are classified as having attempted suicide are those Montana youth in 2017 that reported attempting suicide one or more times during the 12 months prior to taking the YRBS. Fifty separate risk behaviors were queried for association with the attempted suicide question. According to the 20117 YRBS, 9.5 percent of Montana high school students attempted suicide one or more times. Among Montana high school students who had attempted suicide (compared to those who had not attempted suicide), there was a higher percentage of risk behaviors in areas such as substance use, weapons, sexuality, bullying, eating habits, physical activity level, and life style.
