    Article - En anglais

    Fulltext.

    Objectives

    Data from 2 National Health and Nutrition Examination Surveys (NHANES), NHANES II (1976-1980) and NHANES II (1988-1994), were analyzed to examine trends in the prevalence of hepatitis B infection in the United States.

    Methods

    Serum specimens were tested for markers of hepatitis B virus infection, and risk factors were determined from questionnaires.

    Results

    The overall age-adjusted prevalence of hepatitis B virus infection was 5.5% (95% confidence interval [CI]=4.8,6.2) in NHANES II, as compared with 4.9% (95% CI=4.3,5.6) in NHANES III.

    In both surveys, Black participants had the highest prevalence of infection (NHANES II, 15.8% ; NHANES III, 11.9%). No differences in infection were found in the major racial groups between surveys, except for a decrease among those older than 50 years.

    Black race, increasing number of lifetime sexual partners, and foreign birth had the strongest independent associations with hepatitis B virus infection.

    Conclusions

    Testing of participants in 2 national surveys demonstrates no significant decrease in hepatitis B virus infection, despite the availability of hepatitis B vaccine.
