HIV vulnerabilities and coercive sex at same-sex sexual debut among men who have sex with men in Beijing,China

Few studies have examined coercive sex and HIV vulnerabilities among men who have sex with men (MSM) in China. The present study seeks to compare individual characteristics between MSM who did and did not experience coercive sex at their MSM sexual debut and to identify HIV risk factors correlated with coercive sex at MSM sexual debut. In 2007, we recruited 167 MSM in Beijing, China by peer-referred social network sampling. Each participant then completed self-administered questionnaires regarding their sexual experiences and practices. Results show that 14% of participants reported coercive sex at MSM sexual debut, of whom 48% reported recent unprotected anal intercourse (UAI). Coercive sex at MSM sexual debut was significantly associated with UAI [adjusted odds ratio (AOR): 5.38, 95% confidence interval: 1.95–14.87] and lifetime number of male sex partners (AOR: 7.25, 95% CI: 2.39–22.01). Coercive sex is harming MSM in China and should be immediately addressed by researchers, public health officials, and MSM community stakeholders.     

Improving HIV medical care engagement by attending to status disclosure and social support

ABSTRACT

Expeditious linkage and consistent engagement in medical care is important for people with HIV’s (PWH) health. One theory on fostering linkage and engagement involves HIV status disclosure to mobilize social support. To assess disclosure and social support’s association with linkage and engagement, we conducted a qualitative study sampling black and Latino men who have sex with men (MSM of color) in the U.S. Participants' narratives presented mixed results. For instance, several participants who reported delaying, inconsistent access, or detachment from care also reported disclosing for support purposes, yet sporadic engagement suggests that their disclosure or any subsequent social support have not assisted. The findings contribute to the literature that questions disclosure and social support’s influence on care engagement, especially when decontextualized from circumstances and intentions. Our findings suggest the mechanics of disclosure and social support require planned implementation if intending to affect outcomes, especially among MSM of color. From the findings, we explore steps that may bolster interventions seeking to anchor medical care engagement.     

Partner Awareness of the Serostatus of HIV-Seropositive Men Who Have Sex With Men: Impact on Unprotected Sexual Behavior

Prior research has provided conflicting evidence about the association between partner awareness of an HIV-seropositive persons serostatus and HIV transmission behavior via unprotected intercourse. The current study examined partner awareness of participant HIV-seropositive status and sexual behavior in a multiethnic sample of HIV-seropositive men who have sex with men. Most HIV-seropositive men reported that their primary partners are aware, and most reported that at least some non-primary partners are aware the participant was HIV-seropositive before first having sex. Partner awareness of participant HIV-serostatus was related to unprotected sexual behavior during the past 3 months in a non-linear fashion, as men with partners who were inconsistently aware had higher rates of unprotected receptive anal intercourse than men with partners who were consistently aware or consistently unaware. Men with partners who were inconsistently aware also had higher rates of insertive oral intercourse than men with partners who were consistently aware. However, there were no differences in HIV transmission risk behavior between men with partners who were consistently aware and men with partners who were consistently unaware a participant was HIV-seropositive.     

Evaluation of an HIV Prevention Intervention for Men Who Have Sex with Men at Cruising Areas in the Netherlands

This study collected data from 362 men who had sex with men at cruising areas in the Netherlands, and measured characteristics of respondents, sexual risk behavior, and risk perceptions. Furthermore, the study assessed whether outreach activities at cruising areas promote safe sex behavior. Almost one in five respondents reported having sex with both men and women, and 18.5% of respondents reported sexual risk behavior at cruising areas. Men who had a conversation about safe sex with a volunteer used condoms more consistently than men who had not spoken with a volunteer. Finally, it was found that behaviorally bisexual men used condoms less frequently at cruising areas. The relatively high levels of risk-taking sex stress the importance of HIV prevention at cruising areas. Furthermore, special attention could be given to cruising area visitors who have sex with both men and women, because they report higher levels of risk behavior and have less access to safer sex information regarding homosexual behavior.     

Challenges in Research on Drug and Sexual Risk Practices of Men Who Have Sex with Men: Applications of Ethnography in HIV Epidemiology and Prevention

Epidemiological studies of persons who engage in illicit or illegal activities suffer from methodological difficulties in population definition and specification. Additionally, particularly in the context of HIV research, studies often lack the specificity and validity needed to understand and intervene in the behavioral practices by which viral pathogens such as HIV are transmitted. These limitations are particularly complicated in research among populations of drug-involved, men who have sex with men (DU/MSM), a hidden but internally diverse population which varies in both sexual behavior and drug use patterns across a number of complex and interacting dimensions. The challenges become even more profound when we factor in complexities of sexual identity and identity formation, the debilitating effects of multiple sources of stigma, and the economic imperatives that underpin drug and sexual risk practices among some groups of DU/MSM. This paper describes some of the uses of ethnographic methods, particularly participant-observation, in specifying the nature and interrelationship between risk practices among DU/MSM. We also show how ethnography can contribute to the process of disentangling the independent effects of age, period, and cohort factors, a perennial problem in epidemiological research in out-of-treatment populations.

Acute hepatitis C infection in HIV‐negative men who have sex with men

Acute hepatitis C infection is recognized in HIV‐infected men who have sex with men (MSM), but the risk in HIV‐negative MSM remains unclear. We evaluated a population of MSM with acute hepatitis C. From January 2010 to May 2014, all cases of HCV antibody positive HIV‐negative MSM were identified. European AIDS Network criteria were applied to determine acute infection, and 44 individuals fulfilled the criteria for acute hepatitis C. Ten were RNA negative at baseline and classed as prior spontaneous clearance. 15 (34.1%) had a previously negative HCV antibody within 1 year. 11 (25.0%) had significant elevation in ALT levels, and 18 (40.9%) were clinically diagnosed from risk exposure and history. Median age was 37 years (range 24–75). 41 (93.2%) individuals reported unprotected anal sex, 36 with (87.8%) both insertive and receptive intercourse, 4 (9.8%) with receptive intercourse, 1 (2.4%) with insertive intercourse, and no data were recorded for 3 (7.3%) patients. Individuals had an average of 7.3 reported (median 2, range 1–100) partners. 12 (27.3%) engaged in group sex, 11 (25.0%) practised fisting, 11 (25.0%) admitted using drugs during sexual activity, 16 (36.4%) reported nasal, and 9 (20.5%) reported injection drug use. 14 (31.8)% had unprotected sex whilst under the influence of recreational drugs. 29 individuals were aware of a partner's status. 2 (4.5%) individuals had sexual contact with a known HCV monoinfected partner, 13 (29.5%) with a HIV monoinfected partner and 6 (13.6%) with a HCV/HIV coinfected partner. 9 (20.5%) reported a partner/partners with no known infection. No data were available in 14 (31.8%) individuals. 13 (29.5%) individuals had a coexisting STI at the time of acute HCV diagnosis. 8 (18.2%) received HIV postexposure prophylaxis (PEP) within the 6 months prior to the HCV diagnosis (2 were participants in a HIV pre‐exposure prophylaxis trial). 15 (34.1%) individuals achieved spontaneous clearance of HCV, and 11 patients received HCV treatment. Similar to the ongoing epidemic of acute HCV infection in HIV+ MSM, HIV‐negative MSM remain at risk.     

Behavioral intention to take up different types of HIV testing among men who have sex with men who were never-testers in Hong Kong

Human immunodeficiency virus (HIV) testing is an important global prevention strategy but underutilized by local men who have sex with men (MSM). This study investigated the prevalence of behavioral intention to take up HIV testing (specific or any type), in the next six months among MSM who had not been tested for HIV in the last three years (never-testers) in Hong Kong. The data was based on 141 never-testers of 430 MSM who completed the anonymous baseline telephone survey of an ongoing randomized controlled trial from January 2015 to August 2015. Only 17.7% of them showed strong intention to take up any type of HIV testing in the next six months. Adjusted analysis showed that perceived benefit of HIV testing (adjusted odds ratio [AOR]: 1.29, 95% confidence interval [CI]: 1.01, 1.66), perceived psychological barriers of HIV testing (AOR: 0.85, 95%CI: 0.73, 1.00), and perceived self-efficacy in taking up HIV testing (AOR: 1.28, 95%CI: 1.07, 1.52) were significantly associated with behavioral intention to take up any HIV testing. Perceived cue to action from non-governmental organization staff was positively associated with a marginal p-value of 0.077 (AOR: 2.37, 95%CI: 0.97, 5.77). It is warranted to strengthen perceived benefit, remove psychological barriers, and increase perceived self-efficacy related to HIV testing. Innovative and effective health promotions are greatly needed to increase HIV testing coverage among never-testers.
