Continued high risk behaviors in HIV infected drug abusers

To characterize current risk behaviors of HIV drug abusers in the highly active antiretroviral therapy (HAART) era, socio-demographic, medical and behavioral information were obtained and immune measurements determined. High-risk sexual practices were prevalent. Participants diagnosed before 1995 were 6 times more likely to have unprotected sex with HIV+ partners (p = 0.05) and 11 times more likely to use contaminated needles (p = 0.05) than participants with later diagnosis. Consistent condom use was reported by only 7% of the cohort. Many (43%) of the participants reported multiple HIV+ and HIV- concurrent partners. Most (65%), particularly women (OR = 3, p = 0.02), did so for drugs or money. Despite detectable viral loads, 36% reported unprotected anal sex. Antiretroviral-treated men, compared to non-treated, tended to have unprotected anal sex (OR = 2, p = 0.07). The continued high-risk behaviors of HIV drug users, particularly those diagnosed before 1995 and/or on antiretroviral therapy, indicates an urgent need for new public health strategies.
