Sexual Exploitation as a Minor, Violence, and HIV/STI Risk among Women Trading Sex in St. Petersburg and Orenburg, Russia.

Child sexual exploitation (CSE) is a major risk factor for acquiring human immunodeficiency virus/sexually transmitted infections (HIV/STI), violence and other health concerns, yet few studies have examined these associations in Russia until now. This study examines the prevalence of CSE (those entering the sex trade as a minor) among women in the sex trade in Russia and how exposures and behaviors related to violence and HIV/STI structural risks differ from those who entered the sex trade as an adult. Women in the sex trade (N = 896) in St. Petersburg and Orenburg, Russia were recruited via time-location sampling and completed structured surveys. Adjusted logistic regression analyses assessed associations between CSE victimization and HIV risk-related exposures. Of the 654 participants who provided their age at first sexual exploitation, 11% reported CSE prior to age 18. Those who reported CSE were more likely to be organized by others and to be prohibited from leaving a room or house and from using condoms; three-quarters experienced rape when trading sex; a third were involved in pornography before age 18 and they had less education if they entered the sex trade as a minor. In adjusted analyses, those entering the sex trade as a minor were significantly more likely than those entering the sex trade as an adult to report drug use prior to age 18 (AOR = 5.75, 95% CI = 2.53-13.09) to have ≥5 clients/day (past 12 months; AOR = 3.55, 95% CI = 1.56-8.08), to report receiving police assistance (AOR: 3.10, 95% CI = 1.26-7.54), and to have fewer experiences of police extortion (AOR = 0.35, 95% CI = 0.10-1.24). They were four times more likely to participate in pornography before the age of 18 (AOR = 4.08, 95% CI = 1.32, 12.60) and three times more likely to have been sexually abused as child (AOR = 2.93, 95% CI = 1.27, 7.54). Overall, entry as a minor was related to greater risk for victimization and an inability to protect oneself from STI/HIV.

Potential impact of implementing and scaling up harm reduction and antiretroviral therapy on HIV prevalence and mortality and overdose deaths among people who inject drugs in two Russian cities: a modelling study.

BACKGROUND: Most new HIV infections among people who inject drugs (PWID) in eastern Europe and central Asia occur in Russia, where PWID have a high risk of overdose. In Russia, use of opioid agonist therapy (OAT) is prohibited, and coverage of needle and syringe programmes (NSPs) and antiretroviral therapy (ART) is poor. We aimed to assess the effects that scaling up harm reduction (ie, use of OAT and coverage of NSPs) and use of ART might have on HIV incidence and the frequency of fatal overdoses among PWID in two cities in the Ural Federal District and Siberian Federal District, where the prevalence of HIV is high or increasing in PWID. METHODS: In this modelling study, we developed a dynamic deterministic model that simulated transmission of HIV through injection drug use and sex among PWID. We calibrated this model to HIV prevalence data among PWID in two Russian cities: Omsk (which has high but increasing prevalence of HIV among PWID) and Ekaterinburg (which has very high but stable prevalence of HIV). The source data were from research studies supported by the Global Fund to Fight AIDS, Tuberculosis, and Malaria and US Centers for Disease Control and Prevention and surveillance studies from WHO and regional AIDS centres. We modelled the effects of no intervention scale-up (no use of harm reduction measures and 30% of HIV-positive PWID receiving ART) versus combinations of scaling up of OAT, receipt of high coverage of NSPs, and use of ART on the incidence of HIV infections, mortality from HIV, and the frequency of fatal overdoses from 2018 to 2028. FINDINGS: Without intervention, HIV prevalence among PWID in Omsk could increase from 30% in 2018 to 36% (2·5-97·5 percentile interval 22-52) in 2028 and remain high in Ekaterinburg, estimated at 60% (57-67) in 2028. Scaling up OAT to 50% coverage for a duration of 2 years could prevent 35% of HIV infections and 19% of deaths associated with HIV in Omsk and 20% (11-29) of HIV infections and 10% (4-14) of deaths associated with HIV in Ekaterinburg. Further, this scaling up could prevent 33% of overdose deaths over the next 10 years. Scaling up of NSPs and OAT to 50% coverage and tripling recruitment to ART (reaching about 65% of HIV-positive PWID) could prevent 58% (46-69) of HIV infections and 45% (36-54) of deaths associated with HIV in Omsk and 38% (26-50) of HIV infections and 32% (23-41) of deaths associated with HIV in Ekaterinburg by 2028. INTERPRETATION: Legalisation of OAT and increased use of ART and NSPs for PWID are urgently needed to prevent HIV and fatal overdose among PWID in Russia.

Police sexual coercion and its association with risky sex work and substance use behaviors among female sex workers in St. Petersburg and Orenburg, Russia.

BACKGROUND: Extensive research documents that female sex workers (FSWs) in Russia are very vulnerable to abuses from police, including police sexual coercion. However, despite qualitative data suggesting abusive policing practices are more likely for FSWs contending with substance abuse issues and risky sex work contexts, there is a paucity of quantitative study evaluating these associations specifically in terms of police sexual coercion. Such research is needed to guide structural interventions to improve health and safety for FSWs in Russia and globally. OBJECTIVE: The purpose of this study is to assess the prevalence of police sexual coercion among FSWs from two Russian cities, St. Petersburg and Orenburg, and to determine whether riskier sex work behaviors and contexts and substance use behaviors, including both IDU and risky alcohol use, are associated with increased risk for sexual coercion from police. METHOD: FSWs in St. Petersburg and Orenburg were recruited via time-location and convenience sampling and completed structured surveys on demographics (age, education), sex work risks (e.g., violence during sex work) and substance use. Logistic regression analyses assessed associations of substance use and risky sex work with police sexual coercion, adjusting for demographics. RESULTS: Participants (N=896) were aged 15 and older (94% were 20+ years). Most (69%) reported past year binge alcohol use, and 48% reported IDU the day before. Half (56%) reported 4+ clients per day. Rape during sex work ever was reported by 64%. Police sexual coercion in the past 12 months was reported by 38%. In the multivariate model, both current IDU (AOR=2.09, CI=1.45-3.02) and past year binge alcohol use (AOR=1.46, CI=1.03-2.07) were associated with police sexual coercion, as was selling sex on the street (not in venues) (AOR=7.81, CI=4.53-13.48) and rape during sex work (AOR=2.04, CI=1.43-2.92). CONCLUSION: Current findings document the substantial role police sexual violence plays in the lives of FSWs in Russia. These findings also highlight heightened vulnerability to such violence among self-managed and substance abusing FSWs in this context. Structural interventions addressing police violence against FSWs may be useful to improve the health and safety of this population.

Individual-level, network-level and city-level factors associated with HIV prevalence among people who inject drugs in eight Russian cities: a cross-sectional study.

OBJECTIVES: To ascertain HIV prevalence among people who inject drug (injection drug users (IDUs)) in the Russian Federation and identify explanations for the disparity in different cities. DESIGN: Cross-sectional survey with serological testing for HIV and hepatitis C virus prevalent infections. SETTING: 8 Russian cities-Irkutsk, Omsk, Chelyabinsk, Yekaterinburg, Naberezhnye Chelny, Voronezh, Orel and St Petersburg. PARTICIPANTS: In 2007-2009 active IDUs were recruited by respondent-driven sampling with a target sample size of 300 or more in each city. MAIN OUTCOME MEASURES: Participants were administered a questionnaire covering sociodemographics, injection risk and protective behaviours, sexual behaviours, HIV knowledge, experiences with drug treatment and harm reduction programmes and social networks. Participants were tested for HIV and hepatitis C by enzyme immunoassay. Data were analysed to identify individual-level, network-level and city-level characteristics significantly associated with HIV prevalence. Factors significant at p≤0.1 were entered into a hierarchical regression model to control for multicollinearity. RESULTS: A total of 2596 active IDUs were recruited, interviewed and tested for HIV and hepatitis C virus infection. HIV prevalence ranged from 3% (in Voronezh) to 64% (in Yekaterinburg). Although individual-level and network-level variables explain some of the difference in prevalence across the eight cities, the over-riding variable that seems to account for most of the variance is the emergence of commercial, as opposed to homemade, heroin as the predominant form of opioid injected. CONCLUSIONS: The expansion of commercial heroin markets to many Russian cities may have served as a trigger for an expanding HIV epidemic among IDUs in that country.

Clients of street-based female sex workers and potential bridging of HIV/STI in Russia: results of a pilot study.

In Russia, sexual transmission of HIV is increasing and street-based female sex workers (FSW) have a high HIV prevalence, but the role of male clients of FSW in HIV transmission and bridging to the general population has not been studied. Sixty-two male clients completed structured interviews during February-March of 2010 in St. Petersburg Russia. Descriptive analyses focused on condom use with different types of sex partners, substance use, and STI/HIV testing histories. The median lifetime and past 12 month numbers of FSW partners were 10 and 3, respectively. A majority of clients (74%) reported having non-FSW partners during the past 12 months, and nearly half (47%) reported having regular sex partners. Consistent condom use was reported in 61% of relationships with FSW partners and in 43% of relationships with non-FSW partners. A majority of clients (58%) was classified as active or potential bridgers based on having both FSW and non-FSW partners and reporting inconsistent condom use with their non-FSW partners. A majority (61%) also reported concurrent partnerships with FSW and non-FSW partners. Nearly half (48%) of last contacts with FSW partners involved consumption of alcohol by the client. Noninjection and injection drug use in the past 30 days were reported by 15% and 7% of clients, respectively. Twenty-nine percent reported history of a sexually transmitted infection (STI) and 74% reported a previous HIV test; active/potential bridgers were significantly less likely than unlikely bridgers to have ever been tested for HIV. These data signal the potential for HIV/STI transmission among male clients of street-based FSW in St. Petersburg Russia due to their variety of partner types, sub-optimal condom use, and concurrent partnerships. Larger studies are needed to confirm these findings, further explore the roles of alcohol and drug use, and identify effective strategies and interventions for HIV prevention.

Sexual Partners of Street-Based Female Sex Workers in St. Petersburg, Russia: A Model of Partnership Characteristics as a Basis for Further Research.

Street-based sex work in Russia, as in many countries, carries with it a high risk for violence and the transmission of infectious diseases. The male partners of female sex workers are both cause and recipient of such risks. Because little is known about the men, we undertook a preliminary study to determine the feasibility of recruiting and interviewing them, develop typologies that describe partners, and derive hypotheses for further study and risk reduction intervention projects. We were able to conduct open-ended, qualitative interviews with street-based sex workers and, largely through these contacts, their male partners. To these data, we added interviews with social work and medical experts who engage with the sex workers. The text of interviews from 37 respondents were analyzed to identify commonly mentioned partner characteristics in five distinct domains: sociodemographics, behavioral patterns of the partners, motivations in seeking sex services, levels of partner engagement with the sex workers, and the social circumstances that moderate the engagement. Four of the five domains (all but sociodemographics) proved useful in identifying typologies that were best described as populated points in a matrix generated from the intersection of the four domains. The data were too limited to specify which of the points in the matrix are most common, but the points populated are useful in generating hypotheses for further study and in identifying potential avenues for risk reduction interventions.

Drug network characteristics and HIV risk among injection drug users in Russia: the roles of trust, size, and stability.

We investigated the influence of drug network characteristics including trust, size, and stability on HIV risk behaviors and HIV testing among injection drug users (IDUs) in St. Petersburg, Russia. Overall, male and female IDUs who reported having high levels of trust in their drug networks were significantly more likely to share syringes than those with lower levels of trust (OR [95% CI]) 2.87 [1.06, 7.81] and 4.89 [1.05, 21.94], respectively). Male and female IDUs in larger drug networks were more likely to share syringes than those in smaller networks (4.21 [1.54, 11.51] and 4.80 [1.20, 19.94], respectively). Characteristics that were significantly associated with not having been HIV tested included drug network instability among men and larger network size among women. High trust, large size, and instability were positively and significantly associated with syringe sharing and not having been HIV tested. Effectiveness of interventions in Russia to reduce the risk of HIV infection may be enhanced if network characteristics are addressed.
