title: Knowledge of HIV/AIDS prevention and factors associated with condom use among adolescents in northeast Brazil.
abstract: OBJECTIVE
  To assess the knowledge of HIV/AIDS prevention and factors associated with condom use among adolescent.
  
  
  METHODS
  A cross-sectional study was conducted among 410 outpatient adolescents. Association between knowledge on the transmission of HIV/AIDS and variables were analyzed using the chi-square test. Logistic regression model was used to estimate the factors associated to condom use.
  
  
  RESULTS
  The knowledge about HIV/AIDS transmission was high and lower percentages of knowledge were observed regarding the non-transmission of HIV/AIDS. Younger adolescents revealed less knowledge than older adolescents. After multiple logistic regression the following factors were associated with condom use: male gender (p = 0.029), same age between partners (p = 0.002) and having until 1 year elapsed since sexual initiation (p = 0.001).
  
  
  CONCLUSIONS
  The knowledge regarding HIV/AIDS prevention was satisfactory. However, this does not imply that adolescents put such knowledge to use.
