Hepatitis B virus transmission between heterosexuals.

M J Alter, J Ahtone, I Weisfuse

    JAMA
    |September 12, 1986
    PubMed
    Summary

    Heterosexual activity is a significant risk factor for hepatitis B virus (HBV) infection, particularly for white individuals. Increased numbers of sexual partners correlate with higher HBV prevalence, suggesting sexual behavior impacts infection risk.

    Area of Science:

    • Virology
    • Epidemiology
    • Public Health

    Background:

    • Hepatitis B virus (HBV) infection poses a significant global health challenge.
    • Understanding risk factors for HBV acquisition is crucial for targeted prevention strategies.

    Purpose of the Study:

    • To investigate heterosexual activity as a risk factor for acquiring hepatitis B virus (HBV) infection.
    • To assess the association between the number of sexual partners and HBV infection prevalence.

    Main Methods:

    • Study conducted on attendees at a sexually transmitted disease (STD) clinic and university students.
    • Self-administered questionnaires collected data on sexual history and risk factors.
    • Serum samples tested for HBV markers (HBsAg, anti-HBs, anti-HBc).

    Main Results:

    • For white heterosexuals in the STD group, HBV prevalence increased significantly with more recent and lifetime partners.
    • For white heterosexual students, higher numbers of recent and lifetime partners were associated with increased HBV prevalence.
    • No association between sexual activity and HBV prevalence was found in black heterosexuals in the STD group.

    Conclusions:

    • Heterosexual activity, particularly with multiple partners, is a significant risk factor for HBV infection in white populations.
    • The risk of HBV acquisition among sexually active white individuals can be comparable to other high-risk groups.
    • Public health interventions should consider sexual behavior in HBV prevention efforts, especially for at-risk populations.
