ABSTRACT
OBJECTIVE: To measure HIV prevalence and characterize associated risk behaviors among injection drug users (IDU) upon detention in Tehran, Iran. METHODS: A cross-sectional survey included 459 male IDU arrested by police during a police sweep in Tehran in 2006. A questionnaire was completed, and blood was collected for HIV testing. RESULTS: Overall HIV prevalence was 24.4% (95% confidence interval 20.5-28.6). Factors independently associated with HIV infection included history of using an opioid in jail (adjusted odds ratio 2.11, 95% confidence interval 1.26-3.53) and older age (adjusted odds ratio 2.79 for 25-34, 3.01 for 35-44, 4.62 for > or = 45 yr). CONCLUSIONS: This study supports that incarceration is contributing to the increased spread of HIV. Harm reduction programs should be urgently expanded, particularly among incarcerated IDU.
