BACKGROUND: The aim of this study was to investigate the prevalence of hepatitis C virus (HCV) infection in a population of pregnant women in Catalonia and the sociodemographic variables and risk factors associated to this prevalence.
METHODS: A representative sample of the pregnant women in Catalonia (n = 4,551) randomly selected by clusters (hospitals with maternity clinics) was studied. Detection of antiHCV antibodies was performed by the third generation ELISA test. Reactive cases were confirmed with RIBA 3 and MATRIX.
RESULTS: The prevalence of antiHCV was found to be 1% and was not significantly associated with any of the sociodemographic variables studied (age, social and cultural level, origin and residence). A history of blood transfusion, intravenous drug consumption and hepatitis in the sexual partner were the only risk factors associated with the prevalence of infection found on univariate analysis although these were only present in 47% of the antiHCV positive cases detected. The association between the positivity of antiHCV and the history of hepatitis in the partner was lost on stratification of the cases according to the possible existence of history of drug addiction.
CONCLUSIONS: A high proportion of young asymptomatic people (1%) were found to have hepatitis C virus infection with the possible mode of infection not being detected in approximately half of these subjects. In the other half of these cases the infection was found to have been acquired by an intravenous mechanism: blood transfusion or drug use.
