  1. Demographic determinants of hepatitis C virus seroprevalence among blood donors.

    Article - En anglais

    Objective

    - To measure demographic determinants of hepatitis C virus (HCV) seroprevalence among blood donors in the United States.

    Design

    - Cross-sectional epidemiological study.

    Setting

    - Five blood centers in different regions of the United States.

    Subjects

    - A total of 862 398 consecutive volunteer blood donors with one or more nonautologous donations from March 1992 through December 1993.

    Methods

    - Demographic data collection, serological screening with second-generation anti-HCV enzyme immunoassay, and confirmation with anti-HCV recombinant immunoblot.

    Results

    - There were 3126 donors with at least one blood donation confirmed HCV-seropositive, for a crude prevalence of 3.6 per 1000.

    Age-specific HCV seroprevalence rose from 0.5 per 1000 in donors younger than 20 years to a maximum of 6.9 per 1000 in donors aged 30 to 39 years and declined in older age groups.

    There was interaction between age and educational attainment, with 30-to 49-year-olds with less than a high school diploma at highest risk of HCV infection (odds ratio [OR], 33.0 ; 95% confidence interval [CI], 23.0 to 47.2 compared with those younger than 30 years with a bachelor's degree or higher degree).

    Other independent risk factors for HCV seropositivity included male sex (OR, 1.9 ; 95% CI, 1.8 to 2.1), black race (OR, 1.7 ; 95% CI, 1.6 to 1.9), Hispanic ethnicity (OR, 1.3 ; 95% CI, 1.1 to 1.5), previous blood transfusion (OR, 2.8 ; 95% Cl, 2.5 to 3.1), and first/only time donor sta...
