HIV prevalence and risk behaviours among people who inject drugs in Iran: the 2010 National Surveillance Survey
Objectives To assess the prevalence of HIV and related risk behaviours among people who inject drugs (PWID) in Iran. Methods We conducted a national cross-sectional bio-behavioural surveillance survey between March and July 2010, interviewing male PWID from a geographically dispersed sample through a facility-based sampling method. Results We recruited 2480, and tested 2290 PWID. The overall prevalence of HIV was 15.2% (95% CI 9.7% to 23.1%). Among those who had injected drugs over the last month, 36.9% had used a non-sterile needle, and 12.6% had practiced shared injection. Over the past 12 months preceding the interview, 30.4% had sold sex for money, drugs, goods or a favour. In the multivariate analysis, the prevalence of HIV had a positive association with age, while having above high school education, and permanent job were protective. Conclusions Unsafe injection, and sexual risk behaviours are still frequent and the prevalence of HIV among PWID remains high. Intensified efforts are needed to prevent the further spread of HIV among Iranian PWID and their sexual partners
HIV prevalence and related risk behaviours among female sex workers in Iran: results of the national biobehavioural survey, 2010
Objectives To determine the prevalence of HIV and related behavioural risks among Iranian female sex workers (FSW) via the first national biobehavioural surveillance survey. Methods In 2010, 1005 FSW were approached and 872 recruited using facility-based sampling from 21 sites in 14 cities in Iran. We collected dried blood samples and conducted face-to-face interviews using a standardised questionnaire. Data were weighted based on the response rate and adjusted for the clustering effect of the sampling site. Adjustment was performed by weighting based on the sampling fraction of each site using a prior estimate of its total size of the FSW population. Results The prevalence of HIV infection (95% CI) was 4.5% (2.4 to 8.3) overall, 4.8% (2.2 to 9.8) among those who had reported a history of drug use and 11.2% (5.4 to 21.5) among those who had a history of injection drug use. The frequencies of condom use in the last sexual act with paying clients and non-paying partners were 57.1% and 36.3%, respectively. Any drug use was reported by 73.8% of participants, and among this subgroup, 20.5% had a history of injection drug use. Conclusions The prevalence of HIV was considerable among FSW particularly those who had a history of drug injection. A combination of prevention efforts addressing unsafe sex and injection are needed to prevent further transmission of HIV infection
Risk and vulnerability of key populations to HIV infection in Iran; knowledge, attitude and practises of female sex workers, prison inmates and people who inject drugs
Background: In this study data of three national surveys conducted among female sex workers (FSW), prison inmates and people who inject drugs (PWID) were presented and compared in relation to knowledge, attitude, and practises. Methods: The surveys were conducted in 2009 and 2010 and included 2546 PWID, 872 FSW and 5530 prison inmates. Knowledge, attitude and practises towards HIV were measured through similar questions for each category. Results: Over 90% of all participants had ever heard of HIV/AIDS, although only approximately half of them perceived themselves at risk of contracting HIV. More than 80% were able to correctly identify the ways of preventing the sexual transmission of HIV; while more than two-thirds did not use condom in their last sexual contact. Approximately 20% of prisoners and FSW had a history of injecting drugs. Among all participants who have injected drugs, prisoners had the highest unsafe injecting behaviour at the last injection (61%), followed by FSW (11%) and PWID (3%). Conclusions: Despite major efforts to control the HIV epidemic in Iran, the level of risk and vulnerability among prisoners, FSW and PWID is still high. The level of comprehensive knowledge about HIV/AIDS is relatively good; however, their risk perception of contracting HIV is low and high-risk behaviours are prevalent. Therefore, HIV prevention programs should be redesigned in a more comprehensive way to identify the best venues to reach the largest number of people at a higher risk of contracting HIV and decrease their risk overlaps and vulnerability factors
