Space: the new frontier in HIV prevention for young men who have sex with men.

Young men who have sex with men (MSM) in urban areas of the United States continue to be vulnerable to HIV infection. Qualitative data collected with participants in a community level HIV intervention in West Hollywood and Orange County, California, suggest that space -- both actual physical space and the concept of having space -- should be an integral part of an HIV prevention intervention for young MSM. Having such spaces appears to contribute to youth sense of empowerment and efficacy and foster community building, all important components of an effective HIV prevention. Data were drawn from a qualitative research sample of 73. Through narratives, young men describe specific characteristics of the space necessary for effective HIV intervention, including mentoring and supportive staff, tolerant and like-minded peers, information exchange, opportunities for strengthening self-esteem, and a sense of collaborative community invested in social change.     

Successes and challenges of HIV prevention in men who have sex with men

Men who have sex with men (MSM) have been substantially affected by HIV epidemics worldwide. Epidemics in MSM are re-emerging in many high-income countries and gaining greater recognition in many low-income and middle-income countries. Better HIV prevention strategies are urgently needed. Our review of HIV prevention strategies for MSM identified several important themes. At the beginning of the epidemic, stand-alone behavioural interventions mostly aimed to reduce unprotected anal intercourse, which, although somewhat efficacious, did not reduce HIV transmission. Biomedical prevention strategies reduce the incidence of HIV infection. Delivery of barrier and biomedical interventions with coordinated behavioural and structural strategies could optimise the effectiveness of prevention. Modelling suggests that, with sufficient coverage, available interventions are sufficient to avert at least a quarter of new HIV infections in MSM in diverse countries. Scale-up of HIV prevention programmes for MSM is difficult because of homophobia and bias, suboptimum access to HIV testing and care, and financial constraints.     

Unintentional HIV exposures from young men who have sex with men who disclose being HIV-negative

OBJECTIVE: To evaluate the proportion of new sexual partners potentially exposed to HIV from young MSM who disclosed being HIV-negative. DESIGN: Cross-sectional, observational study of men aged 23-29 years recruited from randomly sampled MSM-identified venues in six US cities. METHODS: Participants were interviewed and tested for HIV. Analyses were restricted to MSM who reported last testing HIV-negative and having one or more new partners in the prior 6 months. RESULTS: Of 1701 MSM who reported a total of 11 793 new partners, 1075 (63%) disclosed being HIV-negative to 4253 (36%) new partners before having sex with them for the first time. Of disclosers, 352 (33%) reported last testing HIV-negative > 1 year before their interview and 80 (7%) tested HIV-positive (HIV-infected unaware). By race, 24% of black, 5% of Hispanic, and 3% of white disclosers tested HIV-positive. Of the 4253 new partners, 296 (7%) were partners of the 80 HIV-infected unaware MSM. By race, 22% of new partners of black, 3% of new partners of Hispanic, and 4% of new partners of white MSM, were partners of HIV-infected unaware MSM who disclosed being HIV-negative. CONCLUSIONS: Many new sex partners may be unintentionally exposed to HIV from young MSM, particularly those who are black and who disclose being HIV-negative based on an earlier test. Young MSM should test for HIV more frequently and consistently use condoms with all partners unless they are in a mutually monogamous relationship in which both partners have tested HIV-negative at least 3 months since their last potential HIV exposure.     

Bisexual behavior among Chinese young migrant men who have sex with men: implications for HIV prevention and intervention

Data from 307 young migrant men who have sex with men (MSM) in Beijing were analyzed to examine bisexual behavior and the associated sociodemographic and behavioral factors among Chinese young migrant MSM. More than one-fourth (27%) of the MSM were also concurrently engaged in sexual behavior with women (MSMW). Among MSMW, 8.4% were infected with HIV, and 10.8% with Syphilis, compared to 4.9% and 23.7%, respectively, among men who have sex with men only (MSM-only). Various HIV-related risk behaviors among MSMW were similar to those of MSM-only, such as unprotected anal sex, multiple sexual partners, involvement in commercial sex, and substance use. Compared with MSM-only, MSMW were less likely to have tested for HIV, to participate in HIV prevention activities, and were less knowledgeable about condom use and HIV/AIDS. MSMW also had a higher rate of unprotected sex with female stable sexual partners than with male stable sexual partners (79.5% vs. 59.5%). Results indicated that MSMW were at a very high risk for both HIV infection and transmission. Intervention efforts are needed to target this subgroup of MSM and promote AIDS knowledge and HIV/STD testing among MSMW, and to reduce HIV transmission through MSM's bisexual behavior.     

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.     

Preferences about the characteristics of future HIV prevention products among men who have sex with men.

This study of men who have sex with men (MSM) examined preferences about the characteristics of a potential product for preventing sexual transmission of HIV, such as a rectal microbicide. MSM were recruited in West Hollywood, California. They self-administered a questionnaire and rated 48 product characteristics representing seven dimensions. Overall, the ratings were highest for effectiveness in preventing HIV and other sexually transmitted diseases, followed by characteristics reflecting the physical or secondary effects of the product and logistics of use. Physical attributes, convenience/accessibility, and psychological aspects had intermediate ratings; interpersonal dynamics had the lowest rating. Men with negative attitudes about using condoms to prevent HIV infection were more likely than their counterparts to prefer a product that does not reduce sexual sensation or pleasure, does not break the mood, and can be used after a sexual encounter ends. A similar pattern was observed when participants were stratified by whether or not they had engaged in unprotected anal intercourse in the past 12 months. The findings inform the development, testing, and marketing of a future HIV prevention product for MSM.     

Evaluation of a social network HIV prevention intervention program for young men who have sex with men in Russia and Bulgaria.

HIV prevention, by intervening within social networks, is potentially important but highly understudied. Approaches that systematically identify, train, and enlist known social influence leaders to advise members of their own networks in risk reduction constitute ways to reach hidden population segments, persons who are distrustful of authorities but trust their peers, and those who cannot be reached through traditional professionally delivered counseling. This article illustrates and provides evaluation data on a program that recruited 14 intact social networks of young men who have sex with men (YMSM) in St. Petersburg, Russia, and Sofia, Bulgaria. Sociometric measures were used to identify the social leader of each network, and baseline risk assessment measures were administered to all members of each social network. The sociometrically determined leaders then attended a six-session group program that provided training and guidance in how to carry out theory-based and tailored HIV prevention conversations with members of their own social networks. Four months after leaders completed the program, all network members were readministered risk assessment measures. Pre- to postintervention data revealed that the program produced: (1) increases in the level and comfort with which network members talked about AIDS prevention topics in their daily conversations; (2) increased network-level AIDS risk reduction knowledge and improved risk reduction norm perceptions, attitudes, behavioral intentions, and self-efficacy; and (3) increased condom use levels among network members. Although not a controlled, randomized trial, these program evaluation findings strongly support the feasibility of social network-level HIV prevention approaches.     

HIV risk and prevention among men who have sex with men in rural South Africa

Rural South African men who have sex with men (MSM) are likely to be underserved in terms of access to relevant healthcare and HIV prevention services. While research in urban and peri-urban MSM populations has identified a range of factors affecting HIV risk in South African MSM, very little research is available that examines HIV risk and prevention in rural MSM populations. This exploratory study begins to address this lack by assessing perceptions of HIV risk among MSM in rural Limpopo province. Using thematic analysis of interview and discussion data, two overarching global themes that encapsulated participants’ understandings of HIV risk and the HIV risk environment in their communities were developed. In the first theme, “community experience and the rural social environment”, factors affecting HIV risk within the broad risk environment were discussed. These included perceptions of traditional value systems and communities as homophobic; jealousy and competition between MSM; and the role of social media as a means of meeting other MSM. The second global theme, “HIV/AIDS knowledge, risk and experience”, focused on factors more immediately affecting HIV transmission risk. These included: high levels of knowledge of heterosexual HIV risk, but limited knowledge of MSM-specific risk; inconsistent condom and lubricant use; difficulties in negotiating condom and lubricant use due to uneven power dynamics in relationships; competition for sexual partners; multiple concurrent sexual partnerships; and transactional sex. These exploratory results suggest that rural South African MSM, like their urban and peri-urban counterparts, are at high risk of contracting HIV, and that there is a need for more in-depth research into the interactions between the rural context and the specific HIV risk knowledge and behaviours that affect HIV risk in this population.

Binge use of methamphetamine among HIV-positive men who have sex with men: pilot data and HIV prevention implications.

This study compared the social and behavioral characteristics of binge users and nonbinge users of methamphetamine (meth) in a sample of 90 HIV-positive men who have sex with men. Forty-one participants (46%) self-identified as a binge user. Meth binges ranged from 2 to 33 days (mean = 5.6), and average consumption was 3.1 grams. Binge users were significantly more likely than nonbinge users to be ethnic minority and to have lower education. The two groups did not differ in terms of the total amount of meth used in the past 30 days; however, binge users reported significantly more social difficulties, more mental and physical health problems, and more sexual risk behaviors as compared with nonbinge users. The findings are discussed in relation to drug treatment approaches and the development of behavioral interventions.     

Risk of HIV infection attributable to oral sex among men who have sex with men and in the population of men who have sex with men

We examined HIV infection and estimated the population-attributable risk percentage (PAR%) for HIV associated fellatio among men who have sex with other men (MSM). Among 239 MSM who practised exclusively fellatio in the past 6 months, 50% had three partners, 98% unprotected; and 28% had an HIV-positive partner; no HIV was detected. PAR%, based on the number of fellatio partners, ranges from 0.10% for one partner to 0.31% for three partners. The risk of HIV attributable to fellatio is extremely low.     

Empowering HIV testing as a prevention tool: targeting interventions for high-risk men who have sex with men

In France, HIV testing can be easily performed in free and anonymous voluntary counselling testing (VCT) centres. The recent national study among French men who have sex with men (MSM) showed that 73% of those already tested for HIV had been tested in the previous two years. Nothing is known about the risk behaviours of MSM attending VCT centres. This study aimed to characterize sexual risk behaviours of MSM tested for HIV in such centres and identify factors associated with inconsistent condom use (ICU). A cross-sectional study was conducted from March to December 2009 in four VCT centres where a self-administered questionnaire was proposed to all MSM about to have a HIV test. ICU was defined as reporting non-systematic condom use during anal intercourse with casual male partners. Among the 287 MSM who fully completed their questionnaire, 44% reported ICU in the previous six months. Among those who had been already tested, 63% had had their test in the previous two years. Factors independently associated with ICU included: never avoiding one-night stands, not having been recently HIV tested, experiencing difficulty in using condoms when with a HIV negative partner or when under the influence of drugs or alcohol and finally, reporting to have had a large number of casual male partners in the previous six months. The rate of recently tested MSM was high in our study. Nevertheless, this rate was lower than that found in the last national study. Furthermore those not recently tested were significantly more likely to report high risk behaviours. We therefore recommend that further efforts be made to adapt the offer of both HIV testing and counselling to meet the specific needs of hard-to-reach MSM. Accordingly, an additional community-based offer of HIV testing to reach most-at-risk MSM is forthcoming in France.     

Correlates of high-risk sexual behavior among young men who have sex with men.

Data from a sample (n = 154) of young men who have sex with men (YMSM), aged 13-21, residing in five mid-sized cities in the midwestern United States were used to test the hypothesis that personality variables (impulsive decision making, sensation seeking, anxiety/depression, internalized homophobia) contribute uniquely to the prediction of unprotected anal sex beyond what is accounted for by other high-risk behaviors (i.e., substance use and number of sex partners) and partner status (having a dating partner). Results of hierarchical regression analyses indicated that number of reported anal sex partners and partner status were positively associated with self-reported frequency of unprotected anal sex. Beyond these factors, impulsive decision making significantly contributed to the predictive model. These findings indicate that designing effective prevention programming for YMSM should take into consideration relationship status and the impulsiveness of sexual decision making among members of the target group.     

High prevalence of HIV infection among young men who have sex with men in New York City

OBJECTIVE: To determine the prevalence of HIV infection and risk behaviors among young men who have sex with men (MSM) aged 15-22 years in New York City. DESIGN: An anonymous cross-sectional survey. METHODS: The 1998 Young Men's Survey in New York City (YMS-NYC), was a multistage probability survey of 541 MSM aged 15-22 years who attend public venues. After identification of venues and their associated high attendance time periods, random samples of venues and time periods were selected on a monthly basis. At each sampling event, potential participants were approached to determine eligibility. Eligible and willing men were interviewed, counselled and had a blood specimen drawn. RESULTS: Between December 1997 and September 1998, 115 sampling events were conducted. Of 612 men enrolled, 541 reported ever having had sex with a male partner. The HIV seroprevalence among the 541 MSM sampled was 12.1%. The HIV seroprevalence was 18.4% among African-Americans, 16.7% among persons of mixed race, 8.8% among Latino individuals and 3.1% among white men. HIV seroprevalence was 5.0% among 15-18 year olds and 16.4% among 19-22 year olds. A total of 65.5% of MSM were susceptible to hepatitis B virus infection (HBV). Almost half (46.1%) of the men reported unprotected anal sex in the previous 6 months and 16.3% reported ever having had an STD. Multiple regression analyses found that being older, of mixed race, black or ever having had an STD was associated with being HIV antibody positive. CONCLUSION: These data identify a large subgroup of MSM in need of effective HIV and HBV primary and secondary prevention programs.
