  1. Are there risk factors for hepatitis B infection in inner-city adolescents that justify prevaccination screening ?

    Article - En anglais


    This study was undertaken to determine if homelessness could serve as a marker for previous hepatitis B infection (HBI), and thus justify prevaccination screening.


    One hundred sexually active 13-21-year-olds (mean=17 years), 74% female, attending an inner-city hospital-based adolescent clinic (HOSP), and 48 sexually active 13-21-year-olds (mean=19 years), 40% female, attending a clinic based at an urban drop-in center (UDC) for street youth were consecutively enrolled, screened for HBI serum markers and administered a structured interview about sexual practices, sexual abuse, prior sexually transmitted diseases (STDs), and injection drug use.


    For the HOSP group, 7% were homeless and 4% were HBI positive.

    In the UDC group, 96% were homeless and 23% were HBI positive.

    Homelessness was significantly associated with HBI (rhô<0.001), and this was corroborated by logistic regression analysis (rhô<0.01).

    Other factors significantly associated with HBI in adolescents included a history of anal sex (rhô <=0.002), anal-receptive sex (rhô <=0.01), genital Chlamydia (rhô <=0.03), prostitution (rhô <=0.03), and sexual abuse (rhô <=0.002).

    For both populations, gender, sexual orientation, intravenous drug use, and genital sex were not related to HBI.


    These data indicate that homelessness and associated high-risk sexual practices may be indications for prevaccination screening for HBI in adolescents.
