  1. Hepatitis C in a French population-based survey, 1994 : Seroprevalence, frequency of viremia, genotype distribution, and risk factors.

    Article - En anglais

    The aims of this study were the following : 1) to estimate the prevalence of hepatitis C virus (HCV) antibody (anti-HCV) in a population-based survey of French residents not selected for risk factors ; 2) to investigate the association between anti-HCV seropositivity, viremia, the infecting HCV genotype, and the alanine transaminase (ALT) level ; and 3) to identify risk factors for HCV infection by a nested case control study within this survey sample.

    The anti-HCV seroprevalence survey was performed in 6,283 volunteers (20-to 59-years-old) randomly selected from 45,377 consecutive individuals undergoing routine medical checkup in social security medical centers covering 4 of the 22 « regions » of France.

    Seventy-two volunteers were anti-HCV positive, a crude prevalence of 1.15%. Fifty percent of these positive volunteers also had an abnormal ALT level and 81% were HCV-RNA positive by polymerase chain reaction (PCR).

    The prevalence weighted for age, sex, and place of residence was 1.05% (95% CI : 0.75-1.34).

    The weighted prevalence was lower among men>40-years-old (0.5% ; 95% CI : 0.1-1.0) and was close to 1% in all other age and sex groups.

    Prevalence was inversely correlated with socio-professional status with the highest rate being found among those with no paid employment (2.2% ; 95% CI : 1.3-3.0).

    The HCV prevalence (1.7% ; 95% CI : 1.0-2.3) was highest in southeastern France. (...)
