OBJECTIVE: To investigate the dissemination of human immunodeficiency virus (HIV) and hepatitis C infection in association with sexually transmitted diseases (STDs), sexual practices, and injection drug use. All eligible men and women attending two STD clinics in Alberta, Canada, from May 1994 to May 1995 were studied. STUDY DESIGN: Anonymous, unlinked serosurveys were performed using leftover sera drawn for routine syphilis, hepatitis B, or HIV testing. Self-administered questionnaires collected a wide range of data: demographic, sexual behaviors, condom use, STD history, the exchange of drugs or money for sex, and drug and alcohol use. RESULTS: HIV seroprevalence in the overall sample group (n = 6,668) was 1.5%. Univariate analysis showed significant relationships for age between 30 years and 49 years, men having sex with men, injection drug use regardless of sexual orientation, history of STD, anal sex, and exchanging money or drugs for sex. At the multivariate level, only men having sex with men, injection drug use, and age more than 30 years remained predictive of HIV infection. The prevalence of hepatitis C was 3.4% with significant associations being injection drug use and exchanging money or drugs for sex. CONCLUSION: The behavioral associations between sex practices, injection drug use, and HIV and hepatitis C seroprevalence warrant ongoing investigation. Continuing prevention programs targeted at safer sex practices (particularly for men having sex with men) and the use of clean needles are needed.
