Risk factors for weapon involvement in adolescents vary by race and gender

Dr. Rashmi Shetgiri from Los Angeles Biomedical Research Institute and researchers from University of Texas at Dallas, Southwestern Medical Center, and Johns Hopkins Children's Center used longitudinal data from a national survey conducted during the mid-1990s, when rates of violent crime had been in decline. A subset of students in grades 7-12 were surveyed about weapon involvement in 2 waves, approximately 1 year apart. According to Dr. Shetgiri, "We used the data to identify risk and protective factors for involvement with weapons in the past year, which we defined as carrying a weapon, pulling a gun or knife on someone, or shooting or stabbing someone."

The researchers found that 13% of African American, 10% of Latino, and 7% of white students were involved with weapons. Of those who carried weapons, 17% also had shot or stabbed someone in the previous 12 months. Compared with those who reported no weapon involvement, adolescents who initially reported involvement with weapons were 4-6 times more likely to be involved with weapons a year later. It also was found that boys were 2-4 times more likely than girls to be involved with weapons.

Although there are differences among racial/ethnic groups in specific risk and protective factors for weapon carrying and use, reducing emotional distress, exposure to violence, and alcohol and drug use may decrease the risk of weapon involvement for all adolescents. Notes Dr. Shetgiri, "It is important to also promote educational aspirations, minimize the influence of delinquent peer groups, and focus on family connectedness to appropriately tailor programs for different racial/ethnic groups."
