ABSTRACT

A 2006 survey of street youth at pre-mapped street youth locations in St. Petersburg, Russia, found extremely high HIV seroprevalence (37.4%) among 313 street youth aged 15-19 years of age, strongly associated with injection drug use, which was reported by 50.6% of participants. In response, multi-sectoral social support and prevention measures were instituted. In 2012, we conducted a follow-up survey of 15- to 19-year-old street youth using the same study procedures as in 2006. Of 311 participants, 45 (14.5%) reported injection drug use; 31 participants (10.0%, 95% confidence interval, 6.0%-16.2%) were HIV-seropositive . Predictors independently associated with HIV seropositivity included injection drug use (adjusted prevalence ratio 53.1) and transactional sex (adjusted prevalence ratio 1.3). None of the 178 participants aged 15-17 years were HIV-positive. Thirty of 31 (96.8%) HIV-seropositive individuals reported injection drug use. Street youth in St Petersburg had a 73% decrease in HIV seroprevalence from 2006 to 2012, primarily due to decreased initiation of injection drug use. This marked reduction in the HIV epidemic among street youth occurred after implementation of extensive support programs and socio-economic improvements.

ABSTRACT

HIV transmission is a major health concern. Global efforts are necessary to control the spread of infection. International collaborative studies in countries with high rates of new infections are essential for increasing knowledge on the behavioral, social, and biomedical aspects of HIV/AIDS and HIV transmission. Statistics indicate a growing HIV epidemic in Russia. There are alarming proportions of new cases attributed to heterosexual contact, and HIV is increasingly affecting people in the general population who are not part of any traditional high-risk group. Despite recent advances in HIV prevention, data on effective behavioral prevention approaches are limited. There is minimal evidence to suggest which types of prevention will be effective in reducing the risk for HIV transmission among people at risk in the general population. This article presents a review and discussion of an international research seminar, HIV Prevention Research: Evidence-Based Behavioral Approaches. Local and international interdisciplinary researchers gathered for the purposes of exchanging research results and information about ongoing studies, identifying gaps in knowledge, and discussing promising prevention strategies. The overarching goal was to advance HIV prevention research through scientific integration. The seminar provided an excellent platform for building research capacity in interdisciplinary HIV research in Russia and integrating research efforts with the international research community to contribute to HIV prevention research throughout the world.

ABSTRACT

We evaluated the efficacy of a peer-educator network intervention as a strategy to reduce HIV acquisition among injection drug users (IDUs) and their drug and/or sexual networks. A randomized controlled trial was conducted in St. Petersburg, Russia among IDU index participants and their risk network participants. Network units were randomized to the control or experimental intervention. Only the experimental index participants received training sessions to communicate risk reduction techniques to their network members. Analysis includes 76 index and 84 network participants who were HIV uninfected. The main outcome measure was HIV sero-conversion. The incidence rates in the control and experimental groups were 19.57 (95 % CI 10.74-35.65) and 7.76 (95 % CI 3.51-17.19) cases per 100 p/y, respectively. The IRR was 0.41 (95 % CI 0.15-1.08) without a statistically significant difference between the two groups (log rank test statistic X(2) = 2.73, permutation p value = 0.16). Retention rate was 67 % with a third of the loss due to incarceration or death. The results show a promising trend that this strategy would be successful in reducing the acquisition of HIV among IDUs.
