OBJECTIVES: The Dallas County study of a proposed national household seroprevalence survey was designed to assess the feasibility of conducting a national survey and to estimate the prevalence of human immunodeficiency virus (HIV) and hepatitis B virus infection for Dallas County. Risk behavior data were collected and correlated with HIV infection. METHODS: Participants in this survey represented a probability sample of the county. A self-administered questionnaire on demographic characteristics and HIV risk behavior was completed and a blood sample was obtained. RESULTS: Of the 1724 adults eligible for the survey, 1446 completed the questionnaire and 1374 provided a blood sample. The prevalence estimates were 0.4% for HIV and 7.3% for hepatitis B virus. A strong relationship was observed between HIV and hepatitis B status and risk behavior. CONCLUSIONS: In this study population, receptive anal intercourse and increasing numbers of male partners had the strongest correlation with the prevalence of HIV and hepatitis B virus infection in men. The high level of risk reporting for individuals positive for HIV or hepatitis B suggests that survey participants who engage in risk behaviors were willing to report those behaviors.
