The newest epidemic: a review of HIV/AIDS in Central and Eastern Europe

HIV/AIDS has emerged as a grave public health threat in Central and Eastern Europe and in the Central Asian republics over the past five years. Massive political, social, cultural, and behavioural changes - along with economic upheaval and collapse of the public health infrastructure in many countries - have created circumstances conducive to the rapid spread of HIV. This paper reviews HIV and sexually transmitted disease (STD) data for all countries in the region, as well as behavioural, social, cultural, and other HIV epidemic enabling factors. The epidemiological picture of HIV in the region is mixed. Russia, Ukraine, Moldova and Belarus already have advanced epidemics. Some other countries in the region share similar enabling factors and have seen a very high proportion of their total number of HIV infections detected in only the past 18 months, indicating the emergence of recent epidemics. Several countries are more stable in their HIV incidence. Behavioural studies indicate that risky sexual and injection related practices are common in many vulnerable populations. HIV prevention steps, if taken quickly enough and on a large scale, can limit the scope of the HIV epidemic that is now unfolding in Central and Eastern Europe. This will require new models of government/non-governmental organization cooperation, policy approaches for addressing structural factors underlying the epidemic, and attention to human rights protection.

Prevention of HIV and sexually transmitted diseases in high risk social networks of young Roma (Gypsy) men in Bulgaria: randomised controlled trial

Objective To determine the effects of a behavioural intervention for prevention of HIV and sexually transmitted diseases that identified, trained, and engaged leaders of Roma (Gypsy) mens social networks to counsel their own network members. Design A two arm randomised controlled trial. Setting A disadvantaged, impoverished Roma settlement in Bulgaria. Participants 286 Roma men from 52 social networks recruited in the community. Intervention At baseline all participants were assessed for HIV risk behaviour, tested and treated for sexually transmitted diseases, counselled in risk reduction, and randomised to intervention or control groups. Network leaders learnt how to counsel their social network members on risk prevention. Networks were followed up three and 12 months after the intervention to determine evidence of risk reduction. Main outcome measure Occurrence of unprotected intercourse during the three months before each assessment. Results Reported prevalence of unprotected intercourse in the intervention group fell more than in control group (from 81% and 80%, respectively, at baseline to 65% and 75% at three months and 71% and 86% at 12 months). Changes were more pronounced among men with casual partners. Effects remained strong at long term follow-up, consistent with changes in risk reduction norms in the social network. Other measures of risk reduction corroborated the interventions effects. Conclusions Endorsement and advice on HIV prevention from the leader of a social network produces well maintained change in the reported sexual practices in members of that network. This model has particular relevance for health interventions in populations such as Roma who may be distrustful of outsiders. Trial registration Clinical Trials NCT00310973.

A randomized social network HIV prevention trial with young men who have sex with men in Russia and Bulgaria.

Objective:To evaluate the effects of an HIV prevention intervention with social networks of young men who have sex with men (YMSM) in St. Petersburg, Russia and Sofia, Bulgaria. Design:A two-arm randomized trial with a longitudinally-followed community cohort. Methods:Fifty-two MSM social networks were recruited through access points in high-risk community venues. Network members (n = 276) were assessed to determine risk characteristics, administered sociometric measures to empirically identify the social leader of each network, and counseled in risk reduction. The leaders of 25 experimental condition networks attended a nine-session program that provided training and guidance in delivering ongoing theory-based HIV prevention advice to other network members. Leaders successively targeted network members’ AIDS risk-related knowledge and risk reduction norms, attitudes, intentions, and self-efficacy. Participants were re-administered risk assessment measures at 3- and 12-month follow-ups. Results:Among changes produced, the percentage of experimental network members reporting unprotected intercourse (UI) declined from 71.8 to 48.4% at 3-month follow up (P = 0.0001). The percentage who engaged in UI with multiple partners reduced from 31.5 to 12.9% (P = 0.02). After 12 months, the effects became attenuated but remained among participants who had multiple recent sexual partners, the most vulnerable group. Little change was found in control group networks. Conclusions:Interventions that engage the identified influence leaders of at-risk YMSM social networks to communicate theory-based counseling and advice can produce significant sexual risk behavior change. This model is culturally pertinent for HIV prevention efforts in former socialist countries, as well as elsewhere for other hard-to-reach vulnerable community populations.

AIDS knowledge attitudes and behaviour in Russia : results of a population-based random-digit telephone survey in St Petersburg.

In this paper, we report on the results of what we believe to be the first population-based, random-digit telephone AIDS survey conducted in Russia. Recent and rapidly increasing STD and HIV rates show the extremely urgent need for HIV prevention programmes in Russia. HIV sexual risk behaviour, knowledge, attitudes, and personal concern characteristics were assessed in a sample of men and women aged 15–55 years living in 435 St Petersburg households. Many factors related to high HIV risk were found in this study. Only 6% of respondents reported consistent condom use, and 78% reported that they never or seldom used condoms. At the same time, over 13% had 3 and more sexual partners during the last year and 12% had 10 and more lifetime partners. Occasional or frequent anal sex was reported by 13% of those surveyed. Two-thirds of respondents acknowledged personal risk for getting HIV but fewer than 25% indicated that they had taken steps to reduce the risks. One-third of respondents believed that condoms are not an effective protection against HIV. Forty-eight per cent of respondents believed that HIV could be transmitted through kissing, 56% through mosquito bites, and 29.2% through sharing cigarettes. HIV/AIDS prevention efforts for the general public and also targeted campaigns directed toward high-risk communities must be quickly undertaken in Russia.

Programmes resources and needs of HIV-prevention nongovernmental organizations (NGOs) in Africa Central / Eastern Europe and Central Asia Latin America and the Caribbean.

Abstract This study assessed the programmes, resources, and needs of HIV-prevention nongovernmental organizations (NGOs) in 75 countries in Africa, Central/Eastern Europe and Central Asia, Latin America and the Caribbean. Multiple databases and expert recommendations were used to identify one major HIV-prevention NGO in the capital or a large city in each country, and in-depth interviews were conducted with each NGO Director. Most NGOs are carrying out their programmes with minimal funding and few regularly employed personnel. Most are highly dependent on international donors, but reliance on small grants with short funding periods limits programme development capacity. HIV-prevention activities varied by region, with African NGOs most likely to use peer education and community awareness events; Eastern European NGOs most likely to offer needle exchange; Latin American NGOs to have resource centres and offer risk reduction programmes; and Caribbean organizations to use mass education approaches. Across regions, NGOs most often targeted the general public and youth, although specialized at-risk groups were the additional focus of attention in some regions. Limited funding, governmental indifference or opposition, AIDS stigma, and social discomfort discussing sex were often cited as barriers to new HIV-prevention programmes. NGOs are critical service providers. However, their funding, programmes, and resource capacities must be strengthened if NGOs are to realize their full potential in HIV prevention.

Gender roles and HIV sexual risk vulnerability of Roma (Gypsies) men and women in Bulgaria and Hungary: an ethnographic study

Roma, the largest ethnic minority group in Central and Eastern Europe, have cultures that are traditional, often closed, and autonomous of majority populations. Roma communities are characterized by pervasive social health problems, widespread poverty, limited educational opportunities, and discrimination. Although some evidence suggests high levels of HIV sexual risk behaviour among Roma, little is known about the cultural and social context in which risk behaviour occurs. In-depth interviews were used to elicit detailed information about types of sexual partnerships and sexual risk behaviour practices occurring in them, use and perception of protection, knowledge and beliefs about AIDS and STDs, and sexual communication patterns in a sample of 42 men and women aged 18–52 living in Roma community settlements in Bulgaria and Hungary. Analysis of the interview data revealed that men have great sexual freedom before and during marriage, engage in a wide range of unprotected practices with primary and multiple outside partners, and have much more relationship power and control. In contrast, women are expected to maintain virginity before marriage and then sexual exclusivity to their husbands. Condom use is not normative and is mainly perceived as a form of contraception. Although awareness of AIDS was common, it was generally not perceived as a personal threat. Misconceptions about how HIV is transmitted are widespread, and women – in particular – had very little knowledge about STDs, HIV transmission, and protective steps. There is an urgent need for the development of HIV prevention programs culturally sensitive to Roma populations in Eastern Europe, where HIV rates are rapidly rising.

HIV risk behaviour patterns, predictors, and sexually transmitted disease prevalence in the social networks of young men who have sex with men in St Petersburg, Russia

HIV seroconversions and sexually transmitted diseases (STDs) are often clustered in social networks within community populations. The present study was carried out among men who have sex with men in Russia, where a major HIV epidemic is unfolding, and where social networks have played a historically important role. In all, 38 social networks were recruited into the study, and members of all networks (n = 187) completed risk behaviour assessments and were tested for STDs. About 17% of participants had STDs, and 10% of men had syphilis. Over 64% of men had recent unprotected anal intercourse (UAI), including 51% who did so with main partners, 30% who did so with casual partners, and 32% who had UAI with multiple male partners. The strongest predictor of all risk behaviour indicators and STDs was the social network, to which an individual belonged, supplemented by peer norm perceptions and intentions to practise safer sex. There was a high level of correspondence in behaviour between the social leader of a network and its other members. Social networks should be directly targeted in HIV prevention efforts.

HIV risk characteristics and prevention needs in a community sample of bisexual men in St. Petersburg, Russia

Abstract A new and understudied HIV epidemic is quickly unfolding in the Central and Eastern European countries of the former Soviet Union. Men who have sex with men (MSM) in Russia constitute a population highly vulnerable to sexually-transmitted HIV infection. In a community sample of 434 Russian MSM accessed in gay venues in St. Petersburg, 126 had had both male and female partners in the past three months. In this paper, we report on their risk characteristics. Forty-five per cent of men reported recently engaging in unprotected anal intercourse with their male partners. Respondents had a mean of 3.3 male and 3.4 female partners in the past three months, and most had multiple male and female partners in this time period. There were serious and significant gaps in the AIDS risk knowledge levels of these men, and most believed they had no personal contact with HIV-positive people. Bisexual men were more likely than exclusively gay men to have engaged in commercial sex and tended to have lower AIDS risk knowledge. Although they did not differ in average age, bisexual compared to gay men more recently had their first sex with a man. Multivariate logistic and linear regression analyses showed that condom and safer sex attitudes, perceived norms, AIDS risk knowledge and age at first sex with a man were independent predictors of high-risk behaviour among bisexual men. HIV prevention interventions for bisexual men should address their sexual practices with both male and female partners, correct misconceptions about risk, address behaviour practices rather than gay identity, and recognize risk issues faced by the female partners of bisexual men.

Social Networks, Sexual Networks and HIV Risk in Men Who Have Sex with Men

Worldwide, men who have sex with men (MSM) remain one of the most HIV-vulnerable community populations. A global public health priority is developing new methods of reaching MSM, understanding HIV transmission patterns, and intervening to reduce their risk. Increased attention is being given to the role that MSM networks play in HIV epidemiology. This review of MSM network research studies demonstrates that: (1) Members of the same social network often share similar norms, attitudes, and HIV risk behavior levels; (2) Network interventions are feasible and powerful for reducing unprotected sex and potentially for increasing HIV testing uptake; (3) HIV vulnerability among African American MSM increases when an individual enters a high-risk sexual network characterized by high density and racial homogeneity; and (4) Networks are primary sources of social support for MSM, particularly for those living with HIV, with greater support predicting higher care uptake and adherence.

Identifying, recruiting, and assessing social networks at high risk for HIV/AIDS: methodology, practice, and a case study in St Petersburg, Russia.

Population segments at highest risk for HIV are often hidden, marginalized, and hard to reach by conventional prevention programmes. This pattern is especially true in Central and Eastern Europe, where major HIV epidemics have recently appeared, where population members do not perceive themselves as belonging to a community, and where there is little precedence for strong community-based organization service programmes. In these circumstances, naturally existing intact social networks still can be targeted by prevention programmes. HIV prevention interventions undertaken with at-risk social networks can establish new group norms, reduce the risk behaviour of network members, and can reach ‘hidden’ members of a population known personally to leaders of the social networks. This article illustrates a methodology and a practical description for: (1) accessing high-risk social networks in a community population; (2) identifying and enumerating the membership of the social networks; (3) identifying the social leadership of the networks; and (4) establishing the HIV risk behaviour levels of the recruited networks. To illustrate how social network methods can be applied in the field, the article provides case study reports of HIV prevention fieldwork practice targeting high-risk networks of young men who have sex with men and young heterosexual adults in St Petersburg, Russia. Although there is an extensive conceptual literature on the influence of social networks on risk behaviour, this article describes specific and practical techniques that can be in the development of approaches for social network-based interventions.
