Brief Summary:
The purpose of this study is to conduct a randomized controlled trial to assess the efficacy of a peer-educator intervention focused on injection drug users and their drug and sexual networks. We expect that participants who receive the intervention will demonstrate a reduction in the rate of HIV infection and HIV risk behaviors and members of their risk network will also demonstrate reductions in risk behaviors compared to those in the control group.

Detailed Description:

Intravenous drug use (IDU) is driving the HIV epidemic in Russia; over 90% of all HIV-1 infections have occurred within communities of IDUs. In St. Petersburg (population 5 million), the prevalence of HIV infection in IDUs (estimated population 100,000) leapt from 4% in 1999 to 12% in 2000. At present there are an estimated 5-7 million IDUs, a four-fold increase since the end of the Soviet Union. In St. Petersburg, there has been a three-fold increase in regular IDUs and a nine-fold increase in teenage IDUs during the past five years.

The intervention to be tested in this study draws upon theoretical and empirical evidence suggesting that peer educator programs can have significant effects on the risk-related behaviors of both the educators and the peers whom they educate. Providing peer educator training to IDUs may efficiently cultivate sustainable protective behavioral norms related to injection and sexual risk among the IDU educators' social networks. Prior studies have demonstrated that peer educator programs can realize such normative changes, and it is hypothesized in this study that these normative changes will be reflected in significant reductions in the rates of HIV transmission among the peer educators and the members of their social networks.

Comparison condition: Informed by the Centers for Disease Control model of best practice" standard of care of HIV testing and counseling, participants in the comparison condition will receive risk reduction education and motivational counseling to reduce their risk behaviors.
