ABSTRACT
The aim of the study was to know the prevalence of the hepatitis C virus (HCV) in a non hospital work population by ELISA 3.0 and PCR-Amplicor, as well as its relationship with excessive alcohol intake (more than 280 g/week in men and 168 g/week in women). A transversal seroepidemiologic study was carried out in 1,109 workers of the Empresa Nacional de Electricidad, S.A. (ENDESA). During the annual medical examinations (April 1993-October 1994) the amount of alcoholic beverages each worker had consumed over the 7 days prior to the medical examination was obtained by anamnesis together with a blood sample for different laboratory tests. Sixteen percent of the workers had had excessive alcohol intake. The prevalence of anti HCV antibodies in the study population was 2.4% being up to 4.6% in the workers declaring excessive alcohol consumption and 10.4% if they also presented an elevation in any of the transaminases. The prevalence of the potentially ineffective workers was 1.46%. The prevalence of anti C antibodies by ELISA 3.0 was greater than expected (2.4%) significantly increasing in the population group which declared excessive alcohol intake, thereby demonstrating the relationship between alcohol and hepatitis C.
