IntroductionAmong U.S. high-school students, interpersonal violence and victimizations often occur on school property. The presence of a weapon can increase the potential for injury and death resulting from interpersonal conflict. This study examines the associations between exposure to school violence and weapon carrying on school property among U.S. high-school students.MethodsData from the 2017 and 2019 national Youth Risk Behavior Surveys were combined (N=28,442) and analyzed in 2022. Multivariable logistic regression models were used to calculate sex-stratified, adjusted (for race/ethnicity, grade, sexual identity, current substance use, suicidal thoughts, and history of concussion) prevalence ratios. Prevalence ratios were considered statistically significant if 95% CIs did not include 1.0.ResultsMale students (4.7%) were more likely than female students (1.8%) to report carrying a weapon at school during the 30 days preceding the survey. Weapon carrying at school was more prevalent among students who were threatened or injured with a weapon at school (male students, adjusted prevalence ratio=3.45; female students, adjusted prevalence ratio=3.90), among students who were involved in a physical fight at school (male students, adjusted prevalence ratio=3.44; female students, adjusted prevalence ratio=3.72), among students who missed school because they did not feel safe (male students, adjusted prevalence ratio=1.98; female students, adjusted prevalence ratio=2.97), and among male students who were bullied at school (adjusted prevalence ratio=1.72) than among students who did not experience school violence.ConclusionsIncreased emphasis on safe and supportive school environments, where all types of interpersonal violence are less likely to occur, and increased access to programs and services to promote mental health, prevent violence, and deter weapon use are needed.Published by Elsevier Inc.
