abstract: OBJECTIVE
  To describe the victimization and bullying practice in Brazilian school children, according to data from the National Adolescent School-based Health Survey and to compare the surveys from 2009 and 2012.
  
  
  METHODS
  This is a cross-sectional study with univariate and multivariate analyzes of the following variables: to have been treated badly by colleagues, to have been bullied and to have bullied other children. The following independent variables were analyzed: age, sex, race/color, type of school, maternal education. Prevalence rates were compared between the editions of 2009 and 2012 of the survey.
  
  
  RESULTS
  Of all the adolescents analyzed, 27.5% have not been treated well by peers at school, with greater frequency among boys (OR = 1.50), at the age of 15 years (OR = 1.29) and 16 (OR = 1.41), public school students (OR = 2.08), black (OR = 1.18) and whose mothers had less education; 7.2% reported having been bullied, with a greater chance in younger students (13 years old), male (OR = 1.26), black (OR = 1.15) and indigenous (OR = 1.16) and whose mothers had less education; 20.8% reported to have bullied other children, with a greater chance for older students, at the age of 14 (OR = 1.08) and 15 years (OR = 1.18), male (OR = 1.87), black (OR = 1.14) and yellow (OR = 1.15), children of mothers with higher education, private school students. There was an increase of bullying in the Brazilian capitals, from 5.4 to 6.8%, between 2009 and 2012.
  
  
  CONCLUSIONS
  The occurrence of bullying reveals that the Brazilian school context is also becoming a space of reproduction of violence, in which it is crucial to act intersectorally and to articulate social protection networks, aiming to face this issue.
