| Résumé : | [BDSP. Notice produite par INIST dgq9rR0x. Diffusion soumise à autorisation]. Context Violence-related behaviors such as fighting and weapon carrying are associated with serious physical and psychosocial consequences for adolescents. Objective To measure trends in nonfatal violent behaviors among adolescents in the United States between 1991 and 1997. Design, Setting, and Participants Nationally representative data from the 1991,1993,1995, and 1997 Youth Risk Behavior Surveys were analyzed to describe the percentage of students in grades 9 through 12 who engaged in behaviors related to violence. Overall response rates for each of these years were 68%, 70%, 60%, and 69%, respectively. To assess the statistical significance of time trends for these variables, logistic regression analyses were conducted that controlled for sex, grade, and race or ethnicity and simultaneously assessed linear and higher-order effects. Main Outcome Measures Self-reported weapon carrying, physical fighting, fighting-related injuries, feeling unsafe, and damaged or stolen property. Results Between 1991 and 1997, the percentage of students in a physical fight decreased 14%, from 42.5% (95% confidence interval [Cl], 40.1% 44.9%) to 36.6% (95% Cl, 34.6% - 38.6%) ; the percentage of students injured in a physical fight decreased 20%, from 4.4% (95% Cl, 3.6% - 5.2%) to 3.5% (95% Cl, 2.9% - 4.1%) ; and the percentage of students who carried a weapon decreased 30%, from 26.1% (95% CI, 23.8% 28.4%) to 18.3% (95% Cl, 16.5% - 20.1%).
