Trends of Suicidal Behaviors Among High School Students in the United States: 1991–2017

The results suggest that, over time, black youth have experienced an increase in suicide attempts, which is troubling because attempts are the most prominent risk factor associated with suicide death. For black boys, a significant increase in injury by attempt occurred, which suggests that black boys may be engaging in increasingly lethal means when attempting suicide. Examining trends of suicidal thoughts and behaviors over time by sex and race and ethnicity allow us to determine where to focus prevention and intervention efforts. Future research should examine the underlying reasons for these changes observed in US high school students.
