School-related violence among high school students in the United States, 1993-1995.

Using logistic regression to calculate odds ratios and confidence intervals, this secondary analysis determined statistically significant predictors and prevalence rates for high school students in the United States who carried a weapon, were threatened or injured with a weapon, or were involved in physical fighting on school property from 1993-1995. Geographic region, grade in school, race/ethnicity, and gender were the independent variables. Data regarding school-related violence among adolescents were collected in 1993 and 1995 using the Youth Risk Behavior Survey developed and implemented by the Centers for Disease Control and Prevention. Results indicated gender, race, and grade in school were predictors of school-related violence for students in grades 9-12 from 1993 to 1995. Males were involved in violent acts more often than females. Minority students, especially Hispanics and Blacks, and students in lower grades at school participate in and are victims of violence more often than other students.
