Abstract Objectives.—This study builds on prior research showing a strong relationship between handgun carrying and delinquent behaviors among urban youth by examining the association between handgun carrying trajectories and various types of violence in a rural sample. Methods: This study uses data from a longitudinal cohort study of 2,002 public school students in the United States from 12 rural communities across 7 states from ages 12–26 (2005–2019). We used logistic regressions to assess associations of various bullying and physical violence behaviors with latent trajectories of handgun carrying from adolescence through young adulthood. Results.—Compared to youth with very low probabilities of carrying a handgun in adolescence and young adulthood, trajectories with high probabilities of handgun carrying during adolescence or young adulthood were associated with greater odds of using bullying (odds ratios (ORs) ranging from 1.9–11.2) and higher odds of using physical violence during adolescence (ORs ranging from 1.5–15.9) and young adulthood (ORs ranging from 1.9–4.7). These trajectories with higher probabilities of handgun carrying were also associated with greater odds of experiencing physical violence like parental physical abuse and intimate partner violence, but not bullying. Conclusion and implication.—Experiencing and using bullying and physical violence were associated with specific patterns of handgun carrying among youth growing up in rural areas. Handgun carrying could be an important focus of violence prevention programs among those youth

Community violence, including homicides involving firearms, is a significant public health concern. From 2019 to 2020, firearmrelated homicides increased by 39% for youths and young adults aged 10–24 years, and rates of suicide by firearm increased by approximately 15% among the same age group. Findings from the nationally representative 2021 Youth Risk Behavior Survey were used to analyze disparities and correlates of witnessing community violence and gun carrying among a nationally representative sample of high school students. Chi-square tests and logistic regression accounting for the complex sampling of the survey were used to assess demographic differences by student sex, race and ethnicity, age, and sexual identity in ever witnessing community violence, gun carrying in the past 12 months, and their associations with substance use and suicide risk. Measures of substance use included current binge drinking and marijuana use and lifetime prescription opioid misuse and illicit drug use. Suicide risk included seriously considered attempting suicide and attempted suicide in the past 12 months. Overall, approximately 20% of students witnessed community violence and 3.5% of students carried a gun. American Indian or Alaska Native, Black, and Hispanic students were more likely to witness community violence and to report carrying a gun than their White peers. Males were more likely to witness community violence and carry a gun than females. Lesbian, gay, or bisexual students were more likely to witness community violence than their heterosexual peers. Also, witnessing community violence consistently was associated with increased odds of gun carrying, substance use, and suicide risk for both males and females and when comparing Black, White, and Hispanic students. These findings highlight the importance of comprehensive violence prevention strategies that incorporate health equity to mitigate the effects of violence exposure on substance use and suicide risk among youths.
