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.
Cross-sectional study in IDUs recruited in Catalonia in 2006.
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.
Identification of sociodemographic and behavioral factors associated with these infections can be of help when designing specific preventive interventions for IDUs.
