Trends in violent situations experienced by Brazilian adolescents: National Adolescent Student Health Survey 2009, 2012, and 2015.

OBJECTIVE: To present trends found in the last three editions of the National Adolescent Student Health Survey (Pesquisa Nacional de Saúde do Escolar - PeNSE) on violent situations experienced by Brazilian students.

METHODS: Time-series study with a focus on the Brazilian state capitals, using PeNSE databases of 2009, 2012, and 2015. The indicators evaluated were: missing classes due to insecurity in the home-school route or at school; involvement in a fight with firearm or melee weapon; and physical assault by an adult of the family. We estimated the prevalence of indicators according to the total number of adolescents, gender, school type, and capital. Trends in prevalence were estimated by linear regression, adjusted for age.

RESULTS: We identified a trend in increasing prevalence, with statistical significance, for all selected violence indicators in the period from 2009 to 2015, in Brazilian state capitals.

DISCUSSION: The most vulnerable groups were public schools students; male adolescents for involvement in fights with melee weapons or firearms; and female adolescents for physical assault by family members.

CONCLUSION: PeNSE contributed to identifying the increase in the prevalence of violence experienced by adolescents, which alerts to the need of planning and implementing policies that help to prevent violence, and promote health and a culture of peace.
