title: [Prevalence of human immunodeficiency virus and hepatitis C virus, and associated factors among injecting drug users in Catalonia].
abstract: BACKGROUND
  The objectives of this study were to estimate the prevalence of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) among injection drug users (IDUs) and identify the sociodemographic and behavioral factors in this population associated with these infections.
  
  
  METHODS
  Cross-sectional study in IDUs recruited in Catalonia in 2006.
  
  
  RESULTS
  Ever-sharing syringes was associated with both HIV and HCV infection. Indirect sharing of injecting equipment and injecting cocaine as the main drug were factors associated with HCV infection, and the fact of having injected in prison was associated with HIV infection.
  
  
  CONCLUSIONS
  Identification of sociodemographic and behavioral factors associated with these infections can be of help when designing specific preventive interventions for IDUs.
