Comparison of risk behaviors and socio-cultural profile of men who have sex with men survey respondents recruited via venues and the internet

Patterns of sex behaviors and factors associated with condomless anal intercourse during the COVID-19 pandemic among men who have sex with men in Hong Kong: A cross-sectional study

OBJECTIVES

The present study examined the patterns of sex behaviors before and during COVID-19, and identified the factors associated with condomless anal intercourse during COVID-19 from individual, interpersonal, and contextual level among men who have sex with men (MSM) in Hong Kong.

METHODS

A cross-sectional study was conducted among MSM in Hong Kong. A total of 463 MSM completed a cross-sectional telephone survey between March 2021 and January 2022.

RESULTS

Among all participants, the mean number of regular sex partners, non-regular sex partners, and casual sex partners during the COVID-19 period were 1.24, 2.09, and 0.08 respectively. Among those who had sex with regular, non-regular, and casual sex partner during the COVID-19 period, respectively 52.4%, 31.8% and 46.7% reported condomless anal intercourse. Compared to the pre-COVID-19 period, participants reported significantly fewer number of regular and non-regular sex partners during the COVID-19 period. However, a higher level of condomless anal intercourse with all types of sex partners during the COVID-19 period was also observed. Adjusted for significant socio-demographic variables, results from logistic regression analyses revealed that perceived severity of COVID-19 (aOR = 0.72, 95% CI = 0.58, 0.88), COVID-19 risk reduction behaviors in general (aOR = 0.68, 95% CI = 0.48, 0.96), COVID-19 risk reduction behaviors during sex encounters (aOR = 0.45, 95% CI = 0.30, 0.66), condom negotiation (aOR = 0.61, 95% CI = 0.44, 0.86), and collective efficacy (aOR = 0.79, 95% CI = 0.64, 0.98) were protective factors of condomless anal intercourse with any type of sex partners during the COVID-19 period.

CONCLUSION

The COVID-19 control measures have caused a dramatic impact on the sexual behavior of MSM in Hong Kong. Interventions that promote condom use during the COVID-19 pandemic are still needed and such interventions could emphasize prevention of both COVID-19 and HIV.

Methodologies of Stigma-Related Research Amongst Men Who Have Sex With Men (MSM) and Transgender People in Asia and the Pacific Low/Middle Income Countries (LMICs): A Scoping Review

Much stigma-related research focuses on marginalized populations, including men who have sex with men (MSM) and transgender people. The importance of research in this area is widely recognized, however methodologies and measures vary between studies. This scoping review will collate existing information about how stigma-related research has been conducted in low/middle income countries (LMICs) within the Asia Pacific region, and will compare research designs, sampling frameworks, and measures. Strengths and limitations of these studies will inform recommendations for future stigma-related health research. A methodological framework for scoping studies was applied. Searches of Psych INFO, Scopus, ProQuest, Global Health and PubMed were used to identify articles. Stigma-related research amongst MSM and transgender communities, published between 2010 and 2019 in LMICs within the Asia Pacific region were included. A total of 129 articles based on 123 different studies were included. Of the 129 articles 51.19% (n = 66) were quantitative; 44.96% (n = 57) were qualitative and 3.88% (n = 5) were mixed methods studies. The majority of studies (n = 57; 86.36%) implemented a cross sectional survey. In-depth interviews (n = 20, 34.48%) were also common. Only 3.88% of studies utilized mixed-methods design. Non-probabilistic and probabilistic sampling methods were employed in 99.22 and 0.78% of studies respectively. The most common measures used in quantitative studies were the Center for Epidemiological Study on Depression (CES-D) (n = 18) and the Self Stigma Scale (SSS) (n = 6). Strengths and limitations proposed by researchers included in this review are summarized as lesson learnt and best practices in stigma-related research.

Sexual risk behaviors in the internet age: the case of Chinese men who have sex with men

This cross-sectional study examined a sample of sexually active Chinese MSM recruited online (N = 403) to determine the associations of MSM social life (both online and in-person) and sexual identity stigma with three types of sexual risk behaviors in the past 12 months, including condom use %, number of anal intercourse partners, and number of partners engaged in condomless anal intercourse (CAI). Hierarchical regression analyses were conducted. More frequent use of social media was associated with higher numbers of anal intercourse partners as well as more condom use in past 12 months, but not number of CAI partners. More active in-person MSM social life was associated with higher numbers of partners in anal intercourse as well as CAI. Both perceived and enacted sexual identity stigma associated with higher numbers of CAI partners; perceived stigma was also linked to less condom use. In conclusion, social life and minority stress are relevant factors of sexual risk among MSM in China in the uptrend of internet use. The internet may be an important and promising platform for HIV prevention, and intervention efforts should consider online-based designs to promote safe sex and reduce sexual minority stigma.

Growth Trajectories of Peer Norms, Self-efficacy and Condom Use Behavior Among Sexually Active Chinese Men Who Have Sex with Men: Latent Class Analysis and Growth Mixture Modeling

Data from a randomized controlled trial in 2015 were used to estimate the growth trajectories of peer norms, self-efficacy, and condom use behavior, and to identify associated sociodemographic and behavioral factors among a sample of 804 Chinese men who have sex with men (MSM). Latent class analysis and growth mixture modeling were conducted using Mplus. Two growth trajectories were estimated for each outcome variable with good model fit. The growth trajectories of peer norms were related to age (β = - 0.066, p < 0.05). The growth trajectories of self-efficacy were related to age (β = 0.057, p < 0.01) and using a condom during first sexual encounter with another man (β = 0.777, p < 0.001). The growth trajectories of condom use behavior were related to income (β = 0.366, p < 0.01) and having casual male partners (β = - 1.016, p < 0.001). Predictors for the growth factors within each latent class were also estimated. For subsets of MSM who are older, richer, used a condom during their first sexual encounter with another man, and do not have a casual male partner, condom videos may not have sufficient efficacy and other interventions may be necessary.

HIV Testing Among Chinese Men Who Have Sex with Men: The Roles of HIV Knowledge, Online Social Life, and Sexual Identity Concerns

HIV testing is critical for timely care and controlling the HIV epidemic among men who have sex with men (MSM), particularly for regions with increasing infection rates such as China. This study investigated HIV testing and associated demographic, psychosocial, and risk behavior factors among internet-using Chinese MSM (n = 332). Most participants received HIV testing before (74.1%), which was associated with more HIV knowledge, online social life, and more frequent condomless anal sex. Among MSM who tested previously (n = 246), 48.4% reported regular HIV testing, which was associated with a greater online social life and less sexual identity concerns (internalized homonegativity and concealment motivation). Findings suggest a two-step approach to engage MSM who never tested for HIV and who do not undergo regular testing. Strategies to promote testing should enhance HIV knowledge, sex education, and online MSM community building. Interventions to increase acceptance and positivity of sexual identity are crucial to regular testing.

Coverage and adherence of antiretroviral therapy among Chinese HIV-positive men who have sex with men with high CD4 counts in the era of 'Treat all'

OBJECTIVES

HIV-positive men who have sex with men (MSM) with CD4 cell counts> 350 cells/mm³ in China recently became eligible for free antiretroviral therapy (ART) due to updated national guidelines. This study aimed to investigate ART coverage and adherence among a large sample of HIV-positive MSM in China.

METHODS

A cross-sectional survey was conducted in Chengdu and Hangzhou, China, from February to November 2016. Participants were 277 MSM who had received a confirmatory HIV diagnosis and had CD4 levels of> 350 cells/mm³ . Trained staff of collaborating non-governmental organizations contacted all HIV-positive MSM listed in their service records and invited them to join the study. The ART initiation, ART adherence and interactions between healthcare professionals and the patients were assessed.

RESULTS

ART coverage was 60.3%. Among those who were on ART (n = 167), no participants reported missing any doses in the last four days, but 25.7% reported non-compliance to either ART dosing schedule or dosage instructions. After adjusting for background variables and perceived eligibility for ART, two variables were significant factors of higher ART coverage: (i) receiving a recommendation from healthcare professionals for immediate ART initiation and (ii) perceiving having received an adequate explanation of potential harms of ART. Being prescribed> 3 pills per dose and not having a temporary resident permit were associated with non-compliance.

CONCLUSIONS

Significant efforts are needed to increase ART coverage among HIV-positive MSM with high CD4 counts in China. Although prevalence of missing doses was low, non-compliance to dosing schedule/instructions should not be neglected. Interactions between healthcare professionals and MSMs play an important role in facilitating ART initiation.

Randomised controlled trial of incentives to improve online survey completion among internet-using men who have sex with men

BACKGROUND

HIV prevention research often involves the use of online surveys as data collection instruments. Incomplete responses to these surveys can introduce bias. We aimed to develop and assess innovative methods to incentivise respondents to complete surveys.

METHODS

Adult men who have sex with men (MSM) living in the USA were recruited through banner advertisements on Facebook from 27 April 2015 to 6 May 2015 to participate in an online survey about HIV prevention and risk behaviours. Participants were randomised to one of four conditions: a monetary incentive; a series of altruistic messages highlighting the importance of participating in research; access to a dashboard comparing their responses with statistics from other participants after completion; and no incentive. Kaplan-Meier survival methods and univariate Cox proportional hazard models were used to evaluate survey dropout by incentive group and demographic variables of interest.

RESULTS

There were a total of 1178 participants randomised to the four treatment groups. The rate of survey dropout among participants in the altruistic (HR=0.68, 95% CI 0.49 to 0.93), monetary (HR=0.44, 95% CI 0.32 to 0.61) and dashboard (HR=0.78, 95% CI 0.58 to 1.06) groups was lower than the non-incentivised control group. Regardless of condition, survey dropout was also lower among MSM aged 28-34 (HR=0.67, 95% CI 0.50 to 0.90) compared with those aged 18-22 years old, and MSM who were white (HR=0.78, 95% CI 0.60 to 1.02) compared with non-white participants.

CONCLUSION

Monetary incentives and altruistic messaging can improve survey completion in online behavioural HIV prevention research among MSM.

Providing Online-Based Sexual Health Outreach to Gay, Bisexual, and Queer Men in Ontario, Canada: Qualitative Interviews with Multisectoral Frontline Service Providers and Managers

The Internet is a common tool for gay, bisexual, and other men who have sex with men (MSM) to find sexual partners and sexual health information. Given persistently high human immunodeficiency virus (HIV) infection rates among MSM, it is important to examine the role of online outreach for MSM as part of HIV prevention and care. We provide an overview of the unique perspectives of online sexual health outreach, delivered through AIDS Service Organizations (ASOs) through sociosexual Internet sites and mobile applications. Data were drawn from the qualitative arm of the community-based Cruising Counts study conducted across Ontario from December 2013 to January 2014. ASO online outreach providers and managers (n = 22) were recruited to complete a 1-h in-person/telephone interview to explore in-depth their experiences with, and perspectives on, delivering online outreach services for MSM in Ontario. Thematic analyses were conducted inductively using NVivo 10. Service providers suggested a high demand for online outreach services for MSM. Strengths and advantages of online outreach over face-to-face outreach included anonymity, instant access to services, peer model, and accessing hard-to-reach populations of MSM. Barriers included consistent quality of service, collaborations between companies that own online technologies and outreach service agencies, budgetary and staff capacity issues, and uncertainty of best practices and evaluation parameters for online outreach. Findings from these interviews can inform service providers, policy makers, and researchers on how online sexual health outreach can play a greater role in HIV prevention by better acknowledging and addressing the opportunities and barriers experienced by service providers working with MSM communities online.

Surveillance Among Men Who have Sex with Men in the United States: A Comparison of Web-Based and Venue-Based Samples

Although men who have sex with men (MSM) recruited through web-based and venue-based sampling methods have been compared, no large web-based and venue-based samples using similar survey instruments have been examined in the U.S. This study describes the differences in sociodemographic characteristics and risk behaviors between the 2012 Web-based HIV Behavioral Survey (n = 3221) and 2011 National HIV Behavioral Surveillance (n = 9256). Compared with participants in the venue-based sample, participants in the web-based sample were older, less likely to be black or Hispanic, more likely to have higher socioeconomic status, and more likely to have anal sex without a condom with their last male sex partner. Web-based participants were less likely to have multiple male sex partners, ever injected drugs, been tested for HIV in the past 12 months, and received free condoms than venue-based participants. The method for sampling MSM into a behavioral survey should consider the sub-population of MSM to be reached.

The emergence of ethical issues in the provision of online sexual health outreach for gay, bisexual, two-spirit and other men who have sex with men: perspectives of online outreach workers

BACKGROUND

Mobile applications and socio-sexual networking websites are used by outreach workers to respond synchronously to questions and provide information, resources, and referrals on sexual health and STI/HIV prevention, testing, and care to gay, bisexual and other men who have sex with men (GB2M). This exploratory study examined ethical issues identified by online outreach workers who conduct online sexual health outreach for GB2M.

METHODS

Semi-structured individual interviews were conducted between November 2013 and April 2014 with online providers and managers (n = 22) to explore the benefits, challenges, and ethical implications of delivering online outreach services in Ontario, Canada. Interviews were digitally recorded and transcribed verbatim. Thematic analyses were conducted, and member-checking, analyses by multiple coders, and peer debriefing supported validity and reliability.

RESULTS

Four themes emerged on the ethical queries of providing online sexual health outreach for GB2M: (a) managing personal and professional boundaries with clients; (b) disclosing personal or identifiable information to clients; (c) maintaining client confidentiality and anonymity; and (d) security and data storage measures of online information. Participants illustrated familiarity with potential ethical challenges, and discussed ways in which they seek to mitigate and prevent ethical conflict.

CONCLUSIONS

Implications of this analysis for outreach workers, researchers, bioethicists, and policy-makers are to: (1) understand ethical complexities associated with online HIV prevention and outreach for GB2M; (2) foster dialogue to recognize and address potential ethical conflict; and (3) identify competencies and skills to mitigate risk and promote responsive and accessible online HIV outreach.

Variations in Recruitment Yield and Characteristics of Participants Recruited Across Diverse Internet Platforms in an HIV Testing Study of Young Adult Men-Who-Have-Sex-With-Men (YMSM)

The Internet is a commonly used medium for recruiting geographically dispersed, smaller populations quickly, such as young adult men-who-have-sex-with-men (YMSM). One approach to improve reach and representativeness is to employ multiple Internet platforms to recruit this hard-to-reach population. The utility of this approach has not been studied adequately, and its impact on the study sample recruited is not yet known. Using data from a study of 18- to 24-year-old HIV-uninfected, Black, Hispanic, and White United States (US) YMSM, this investigation compared advertising and enrollment metrics and participant characteristics of those recruited across Internet platforms. Of the 2,444 participants, their median age was 22 years old; 21% were Black, 37% Hispanic, and 42% White; 90% had been tested for HIV at least once in their life; and 87% reported prior condomless anal intercourse (CAI) with another man. There were noticeable differences across platforms in the number of people accessing the study website, meeting study eligibility requirements, consenting to participate, consenting to participate per day of advertising and per click, as well as costs of advertising per consented participant. Participants recruited also varied across platform by race/ethnicity, geographic area of residence in the US, health-care insurance status, years of formal education, history of HIV testing, and CAI by partner type and sexual positioning. The investigation results indicate that the Internet platforms used for recruitment significantly impact not only enrollment but also diversity and characteristics of the sample obtained and consequently, the observations and conclusions rendered.

Use of Videos Improves Informed Consent Comprehension in Web-Based Surveys Among Internet-Using Men Who Have Sex With Men: A Randomized Controlled Trial

Background

Web-based surveys are increasingly used to capture data essential for human immunodeficiency virus (HIV) prevention research. However, there are challenges in ensuring the informed consent of Web-based research participants.

Objective

The aim of our study was to develop and assess the efficacy of alternative methods of administering informed consent in Web-based HIV research with men who have sex with men (MSM).

Methods

From July to September 2014, paid advertisements on Facebook were used to recruit adult MSM living in the United States for a Web-based survey about risk and preventive behaviors. Participants were randomized to one of the 4 methods of delivering informed consent: a professionally produced video, a study staff-produced video, a frequently asked questions (FAQs) text page, and a standard informed consent text page. Following the behavior survey, participants answered 15 questions about comprehension of consent information. Correct responses to each question were given a score of 1, for a total possible scale score of 15. General linear regression and post-hoc Tukey comparisons were used to assess difference (P<.001) in mean consent comprehension scores. A mediation analysis was used to examine the relationship between time spent on consent page and consent comprehension.

Results

Of the 665 MSM participants who completed the comprehension questions, 24.2% (161/665) received the standard consent, 27.1% (180/665) received the FAQ consent, 26.8% (178/665) received the professional consent video, and 22.0% (146/665) received the staff video. The overall average consent comprehension score was 6.28 (SD=2.89). The average consent comprehension score differed significantly across consent type (P<.001), age (P=.04), race or ethnicity (P<.001), and highest level of education (P=.001). Compared with those who received the standard consent, comprehension was significantly higher for participants who received the professional video consent (score increase=1.79; 95% CI 1.02-2.55) and participants who received the staff video consent (score increase=1.79; 95% CI 0.99-2.59). There was no significant difference in comprehension for those who received the FAQ consent. Participants spent more time on the 2 video consents (staff video median time=117 seconds; professional video median time=115 seconds) than the FAQ (median=21 seconds) and standard consents (median=37 seconds). Mediation analysis showed that though time spent on the consent page was partially responsible for some of the differences in comprehension, the direct effects of the professional video (score increase=0.93; 95% CI 0.39-1.48) and the staff-produced video (score increase=0.99; 95% CI 0.42-1.56) were still significant.

Conclusions

Video-based consent methods improve consent comprehension of MSM participating in a Web-based HIV behavioral survey. This effect may be partially mediated through increased time spent reviewing the consent material; however, the video consent may still be superior to standard consent in improving participant comprehension of key study facts.

Seeking Male Sexual Partners via Internet and Traditional Venues among Chinese Men Who Have Sex with Men: Implications for HIV Risk Reduction Interventions

The dynamic nature of finding male sexual partners (sex-finding) among Chinese men who have sex with men (MSM) may play a substantial role in the HIV epidemic. We compared characteristics and behaviors of MSM who mostly sought sex via the Internet versus traditional venues in a cross-sectional survey among 3588 Chinese MSM. We assessed the sociodemographic predictors and compared high-risk behaviors of using Internet versus traditional venues for sex-finding. Compared to non-Internet MSM, Internet-user MSM were more likely to have been: younger, currently single, better educated, health-insured, with higher income, with Beijing residency ('Hukou'), living longer in the city, HIV-positive, ever using drug and engaging in condomless receptive anal sex. Internet sex-finding users were less likely to be sexually active for longer duration, drink alcohol, drink alcohol before sex, or ever have sex with women. Knowledge of differential characteristics of various sex-finding MSM can help design targeted interventions.

Association of Situational and Environmental Factors With Last Episode of Unprotected Anal Intercourse Among MSM in Hong Kong: A Case-Crossover Analysis

This study investigates event-specific factors that differentiate the last episodes of unprotected anal intercourse (UAI) from protected anal intercourse (PAI) with regular partner (RP) among 213 men who have sex with men (MSM) who did not use condoms consistently using case-crossover analysis. Factors positively associated with the last episode of UAI with RP included: two situational factors (i.e., participant's suggestion to have UAI, alcohol use) and three environmental/setting factors (i.e., sex took place overseas, during a weekday and not at home). Negative associations with an episode of UAI with RP included: five situational factors (i.e., discussion about condom use prior to sex, RP's suggestion to have PAI, participant's suggestion to have PAI, perception that RP would like to use a condom, participant's planning to use a condom) and two environmental/setting factors (i.e., condoms placed at the venue where sex took place, partner possessed a condom). Thus, these significant event-specific factors explained under which circumstances some MSM would use and would not use condoms during anal sex with RP.

Migration and HIV Risk Among Men Who Have Sex With Men, San Francisco, 2011

In San Francisco, MSM account for nearly 90% of HIV infections. Studies have postulated increased risk for HIV faced by MSM who migrate, particularly to urban environments, yet empirical data are lacking. In this study we analyzed data from the National HIV Behavioral Surveillance System collected in 2011 to ascertain whether nativity (U.S. versus foreign born) was associated with HIV prevalence, risk behavior, and service use. Among 510 MSM enrolled, HIV prevalence was 23.0%. Multivariable analyses demonstrate that while nativity was not associated with increased risk for HIV infection, those who had lived in San Francisco for more than five years had higher HIV prevalence compared to those who had lived for less than a year even after adjusting for age, race, income, education, and location of birth.

Comparing databases: determinants of sexually transmitted infections, HIV diagnoses, and lack of HIV testing among men who have sex with men

Background

Early detection and treatment of STI/HIV are public health priorities. Our objective was to compare characteristics of men who have sex with men (MSM) in Dutch data available in 2010 from EMIS, an international internet survey, Schorer Monitor, a Dutch internet survey, and data from STI- clinic visits, since these might be subject to different and unknown biases.

Methods

Data from Dutch MSM Internet Surveys (EMIS_NLN = 3,787; Schorer Monitor, SMON N = 3,602), and 3,800 STI clinic visits (SOAP) were combined into one dataset. We included factors that were measured in all three databases. The socio-demographics included were age (at the time of the survey), zip code, and ethnicity. Behavioural variables included were the number of sexual partners, condom use with last sexual partner, drug use, being diagnosed with STI, being diagnosed with HIV, and HIV testing. Outcomes we investigated were being diagnosed with STI, HIV, and never been tested for HIV.

Results

Logistic regressions showed that determinants for being diagnosed with STI were having more sexual partners, drug use, and having had an HIV test (aORs 1.3 to 17.1) in EMIS and SMON. Determinants for being diagnosed with HIV in all three databases were older age, living in Amsterdam, and having more partners (aORs 1.8 to 4.4). In EMIS and SMON, drug use, non-condom use, and having STI were additional determinants (aORs 1.6 to 8.9). Finally, determinants associated with never been tested for HIV were being younger (only SOAP), living outside of Amsterdam, having fewer partners, no drug use, and no STI (aORs 0.2 to 0.8).

Conclusions

Risk factors from internet surveys were largely similar, but differed from STI clinics, possibly because it involves self-reports rather than diagnoses or because of differences in timing. The difference between the internet surveys and STI clinic data is much less pronounced for having never been tested, suggesting both are appropriate for this outcome. These findings shed light on conclusions drawn from different data sources, as well as the comparability of recruitment strategies, the robustness of risk factors, consequences of phrasing questions differently, and on (policy) implications based on different data sources.

A comparison between respondent-driven sampling and time-location sampling among men who have sex with men in Shenzhen, China

Men who have sex with men (MSM) are a key population for HIV control and prevention in China. It is difficult to acquire representative samples of this hidden population. Respondent-driven sampling (RDS), based on peer referral, and time-location sampling (TLS) based on random selection of venue-day-time periods, are among the most commonly used sampling methods. However, differences in HIV-related characteristics of MSM recruited by these two methods have not been fully evaluated. We compared sociodemographics, risk behaviors, utilization of HIV-related intervention services, and HIV/syphilis infection rates between samples of 621 RDS MSM and 533 TLS MSM in Shenzhen, China in 2010. We found that the HIV prevalence was comparable in RDS and TLS MSM. TLS recruited larger proportions of more marginalized MSM than RDS: MSM recruited by TLS were older, less educated and more likely to be migrants (without Shenzhen hukou registration), to be non-gay identified and to engage in risky sexual behaviors. On the other hand, MSM recruited by TLS were more likely to have been covered by HIV-related intervention services. To conclude, in Shenzhen, TLS is more effective to reach the marginalized population of MSM. But because TLS can only reach MSM who physically attend venues and HIV-related intervention services are already commonly available at gay venues in Shenzhen, RDS is more informative for allocating prevention efforts than TLS. Furthermore, researchers and public health authorities should take into account the different sample compositions of RDS and TLS and apply sampling methods consistently when evaluating trends over time.

HIV Prevalence and Awareness of Positive Serostatus Among Men Who Have Sex With Men and Transgender Women in Bogotá, Colombia

OBJECTIVES

We estimated HIV prevalence among men who have sex with men (MSM) and transgender women in Bogotá, Colombia, and explored differences between HIV-positive individuals who are aware and unaware of their serostatus.

METHODS

In this cross-sectional 2011 study, we used respondent-driven sampling (RDS) to recruit 1000 MSM and transgender women, who completed a computerized questionnaire and received an HIV test.

RESULTS

The RDS-adjusted prevalence was 12.1% (95% confidence interval [CI] = 8.7, 15.8), comparable to a previous RDS-derived estimate. Among HIV-positive participants, 39.7% (95% CI = 25.0, 54.8) were aware of their serostatus and 60.3% (95% CI = 45.2, 75.5) were unaware before this study. HIV-positive-unaware individuals were more likely to report inadequate insurance coverage, exchange sex (i.e., sexual intercourse in exchange for money, goods, or services), and substance use than other participants. HIV-positive-aware participants were least likely to have had condomless anal intercourse in the previous 3 months. Regardless of awareness, HIV-positive participants reported more violence and forced relocation experiences than HIV-negative participants.

CONCLUSIONS

There is an urgent need to increase HIV detection among MSM and transgender women in Bogotá. HIV-positive-unaware group characteristics suggest an important role for structural, social, and individual interventions.

Comparing Samples of Men Who Have Sex with Men Recruited Online and in Venues, Jiangsu Province, China, 2013

PURPOSE

Two common methods to sample men who have sex with men (MSM) for HIV research are venue- and internet-based approaches. However, it is unclear which is best to sample Chinese MSM.

METHODS

We conducted side-by-side comparisons of time-location sampling (TLS) and an online sample of MSM in Nanjing, China.

RESULTS

TLS-recruited MSM tended to be older and of lower socio-economic status compared to online-recruited MSM, whereas online-recruited MSM reported higher risk behavior and lower frequency of HIV testing.

CONCLUSION

Significant differences were observed between the two separate samples. Without a gold standard, the choice of sampling method or recruitment approach should be guided by the segment of the population targeted to be reached.

A mixed-methods study on the acceptability of using eHealth for HIV prevention and sexual health care among men who have sex with men in China

Background

Human immunodeficiency virus (HIV) infection disproportionately affects men who have sex with men (MSM). Over half of all HIV-positive MSM in China may not know their HIV status. Mobile phones and Web interventions (eHealth) are underutilized resources that show promise for supporting HIV education, testing, and linkage to care.

Objective

This mixed-methods study among MSM in China assessed technology utilization and eHealth acceptability for sexual health care.

Methods

We conducted in-depth interviews and an online survey. Qualitative analyses informed the development of the Internet survey, which was administered through two popular MSM websites. Bivariate and multivariate analysis assessed characteristics of MSM interested in eHealth for sexual health care.

Results

The qualitative sample included MSM across a range of ages, education, marital status, sexuality, and HIV testing experience. Qualitative findings included the importance of the Internet as the primary source of information about sexual health, HIV and other sexually transmitted diseases (STDs), use of the Internet to enable HIV testing opportunities by facilitating connections with both the gay community and health care providers, and mixed perceptions regarding the confidentiality of eHealth tools for sexual health. Among the Internet sample (N=1342), the average age was 30.6 years old, 82.81% (1098/1342) were single, and 53.42% (711/1331) had completed college. In the past 3 months, 38.66% (382/988) had condomless sex and 60.53% (805/1330) self-reported having ever tested for HIV. The majority of men owned computers (94.14%, 1220/1296) and mobile phones (92.32%, 1239/1342), which many had used to search for HIV/STD information and testing sites. In multivariate analysis, interest in using computers or mobile phones to support their sexual health care was associated with being a student, prior use of computers or mobile phones to search for general health information, prior use of computers or mobile phones to search for HIV/STD information, and confidentiality concerns.

Conclusions

MSM in this sample had high utilization of technology and interest in eHealth despite confidentiality concerns. Future eHealth interventions can thoughtfully and creatively address these concerns as a priority for successful implementation.

Setting the scene: locations for meeting sex partners among behaviorally bisexual men in Vientiane, Laos, and opportunities for health promotion

Behaviorally bisexual men (BBM) in Vientiane, Laos report high-risk sexual behaviors. We explore settings for meeting sex partners and associated risk behaviors among BBM in Laos. BBM and their sexual partners were recruited in Vientiane Capital using modified snowball sampling (2010). Settings for usually meeting sex partners and associations with risk behaviors were assessed. Among 88 BBM, the most common settings for men meeting male, kathoey, and female sex partners were private residences (48%, 37%, 51%, respectively) and hospitality settings (39%, 31%, 40%, respectively). Hospitality settings were more commonly reported by heterosexual-identifying BBM, and private residences more commonly reported by bisexual/homosexual-identifying BBM. Inconsistent condom use was high across partners and settings. Meeting partners in hospitality settings was associated with reporting a high number of female sex partners and frequently drinking alcohol before sex. Our results suggest that targeted health promotion initiatives in bars, clubs, and beer-shops could reach a high proportion of high-risk bisexual men, particularly heterosexual-identifying BBM.

Event-specific risk factors predicting episodes of unprotected anal intercourse with male nonregular partners among men who have sex with men using case-crossover study design

This study investigated event-specific factors that determine episodes of unprotected and protected anal intercourse (UAI and PAI) among 215 men who have sex with men (MSM), who used condoms inconsistently with nonregular partners (NRP) in the last six months, in Hong Kong. A case-crossover study design was used. Lower likelihood of episodes involving UAI with NRP was associated with (1) five partner attributes (NRP were <35 years old, at least three previous anal sex experiences with the NRP, perception that participant and the NRP had asymmetrical sexual experience, perception that the NRP was feminine, and liking toward the NRP; OR = 0.16-0.52), (2) six situational variables (the participant having had UAI with another man in the last week, having discussed condom use, perception that the NRP liked to use condom, partner's suggestion to have PAI, participant's suggestion to have PAI, and participant's plan to use condoms; OR = 0.11-0.39), and (3) four environmental/setting variables (condoms already placed at the venue, display of condom use promotion materials, participant's possession of a condom, and the NRP possessed a condom; OR = 0.27-0.45). HIV prevention targeting MSM should focus on event-specific protective factors, which may be different from those obtained from studies distinguishing condom users versus nonusers.

Prevalence of unprotected anal intercourse in men who have sex with men recruited online versus offline: a meta-analysis

Background

Men who have sex with men (MSM) are a high risk population for human immunodeficiency virus (HIV) infection. Our study aims to find whether MSM who were recruited online had a higher prevalence of self-reported unprotected anal intercourse (UAI) than those who were recruited offline.

Methods

A meta-analysis was conducted from the results of published studies. The analysis was stratified by the participants’ geographic location, the sample size and the date of the last reported UAI.

Results

Based on fourteen studies, MSM who were recruited online (online-based group) reported that 33.9% (5,961/17,580) of them had UAI versus 24.9% (2,700/10,853) of MSM who were recruited offline (offline-based group). The results showed that it is more likely for an online-based MSM group to have UAI with male partners than an offline-based MSM group [odds ratio (OR) = 1.35, 95% CI = 1.13-1.62, P < 0.01]. The subgroup analysis results also showed that the prevalence of UAI was higher in the European subsample (OR = 1.38, 95% CI = 1.17-1.63, P < 0.01) and in sample sizes of more than 500 individuals (OR = 1.32, 95% CI = 1.09-1.61, P < 0.01) in the online group compared to the offline group. The prevalence of UAI was also significantly higher when the time of the last UAI was during the last 3 or more months (OR = 1.40, 95% CI = 1.13-1.74, P < 0.05) in the online group compared to the offline group. A sensitivity analysis was used to test the reliability of the results, and it reported that the results remained unchanged and had the same estimates after deleting any one of the included studies.

Conclusions

A substantial percentage of MSM were recruited online, and they were more inclined to engage in UAI than MSM who were recruited offline. Targeted interventions of HIV prevention programs or services are recommended when designing preventive interventions to be delivered via the Internet.

Alcohol use among Chinese men who have sex with men: an epidemiological survey and meta-analysis

The HIV/AIDS epidemic among Chinese men who have sex with men (MSM) has become a significant public health concern. Knowledge of alcohol consumption in this population is limited. In this study, 1,155 Chinese MSM were surveyed to assess alcohol use and its correlates. A meta-analysis was also performed to aggregate pooled prevalence of current alcohol use. MSM who were unmarried (aOR: 1.87; 95% CI: 1.29-2.71) or unemployed/retired (aOR: 2.77; 95% CI: 1.73-4.45) were more likely to drink alcohol more than once per week. MSM who consumed alcohol more than once per week were more likely to use drug (P < 0.01), have sex with women (P < 0.01), have unprotected insertive (P = 0.04) or receptive (P = 0.03) anal sex with men, have more than 10 lifetime male sex partners (P < 0.01), predominantly practice insertive anal sex (P < 0.01), and trade sex for money (P < 0.01). Pooled overall alcohol use prevalence was 32%. Pooled prevalence for MSM who drank alcohol more than once per week and who drank alcohol before sex with male partners was 23%. Our findings provide the basis for further exploring the alcohol-HIV association and developing risk reduction interventions.

Correlates of consistent condom use among men who have sex with men recruited through the Internet in Huzhou city: a cross-sectional survey

Background

There is growing evidence that men who have sex with men (MSM) are currently a group at high risk of HIV infection in China. Our study aims to know the factors affecting consistent condom use among MSM recruited through the internet in Huzhou city.

Methods

An anonymous cross-sectional study was conducted by recruiting 410 MSM living in Huzhou city via the Internet. The socio-demographic profiles (age, education level, employment status, etc.) and sexual risk behaviors of the respondents were investigated. Bivariate logistic regression analyses were performed to compare the differences between consistent condom users and inconsistent condom users. Variables with significant bivariate between groups’ differences were used as candidate variables in a stepwise multivariate logistic regression model. All statistical analyses were performed using SPSS for Windows 17.0, and a p value < 0.05 was considered to be statistically significant.

Results

According to their condom use, sixty-eight respondents were classified into two groups. One is consistent condom users, and the other is inconsistent condom users. Multivariate logistic regression showed that respondents who had a comprehensive knowledge of HIV (OR = 4.08, 95% CI: 1.85-8.99), who had sex with male sex workers (OR = 15.30, 95% CI: 5.89-39.75) and who had not drunk alcohol before sex (OR = 3.10, 95% CI: 1.38-6.95) were more likely to be consistent condom users.

Conclusions

Consistent condom use among MSM was associated with comprehensive knowledge of HIV and a lack of alcohol use before sexual contact. As a result, reducing alcohol consumption and enhancing education regarding the risks of HIV among sexually active MSM would be effective in preventing of HIV transmission.

HIV and syphilis prevalence among men who have sex with men: a cross-sectional survey of 61 cities in China

BACKGROUND

Human immunodeficiency virus (HIV) has rapidly spread among men who have sex with men (MSM) in China in recent years; the magnitude of the epidemic is unclear. We sought to test 3 hypotheses: (1) The prevalence of both HIV and syphilis among MSM in China is high, (2) the 2 epidemics each have unique geographical distributions, and (3) demographic and sexual behavior characteristics are different among segments of the MSM population in China.

METHODS

A total of 47 231 MSM from 61 cities in China participated in a cross-sectional survey conducted from February 2008 to September 2009. Demographic and behavioral data were collected and analyzed and blood samples tested for HIV and syphilis. Three subgroups among the broader MSM sample were described. Main outcome measures were HIV and syphilis prevalence.

RESULTS

An overall prevalence of 4.9% (2314/47 231; 95% confidence interval [CI], 4.7%-5.1%) for HIV and 11.8% (5552/47 231; 95% CI, 11.5%-12.0%) for syphilis was found. Syphilis-positive MSM had the highest HIV prevalence, 12.5% (693/5552; 95% CI, 11.6%-13.4%). However, correlations between HIV and syphilis prevalence were found in only 3 of 6 geographical regions (Northwest: r = 0.82, P = .0253; East: r = 0.78, P = .0004; and South-central: r = 0.63, P = .0276). Three subgroups-nonlocal MSM, Internet-using MSM, and female-partnering MSM-were found to have different profiles of characteristics and behaviors.

CONCLUSIONS

HIV and syphilis prevalences among MSM in China are high and the 2 epidemics are largely separate geographically. Three segments of the Chinese MSM population each have different demographic and sexual risk "profiles" that suggest high potential for bridging infection across geographies, generations, and sexes.

High prevalence of HIV and syphilis among men who have sex with men recruited by respondent-driven sampling in a city in Eastern China

Increasing prevalence of sexually transmitted diseases (STD) was reported among men who have sex with men (MSM) in China. A total of 407 MSMs were recruited by respondent-driven sampling (RDS) from May to July 2008 in Nanjing, China. Face-to-face interviews were conducted to collect information on demographic and risk behaviors; blood samples were collected for HIV and syphilis antibodies testing. The adjusted HIV and syphilis prevalence were, respectively, 7.3% (confidence interval [CI] = 2.6%-10.2%) and 14.4% (95% CI = 9.3%-21.1%). Recruiting male sex partners mostly from saunas and receptive anal intercourse with men in the last 6 months were independently associated with positive HIV status. Risk factors for positive syphilis status included being older than 28 years, low level of HIV-related knowledge, having been a male sex worker, and having unprotected anal sex with casual male sex partners in the past 6 months. High HIV/STD prevalence was detected. HIV/STD prevention strategies are urgently warranted.

Recruiting drug using men who have sex with men in behavioral intervention trials: a comparison of internet and field-based strategies

Although online and field-based samples of men who have sex with men (MSM) have been compared on a variety of markers, differences in drug use have not been well examined. In addition, generalization from studies comparing recruitment methods is often limited by a focus on either HIV seropositive or seronegative MSM. We compared two New York City-based samples of MSM recruited simultaneously between July 2009 and January 2010-one sample recruited in the field (n = 2,402) and one sample recruited via the Internet (n = 694). All recruitment efforts targeted men without restriction on age or self-reported HIV status. Our results show marked differences in drug and alcohol use between online and field-based samples of MSM. Specifically, men surveyed online were significantly more likely to have tried a variety of drugs, including methamphetamine, cocaine, and ecstasy. Men recruited online were also more likely to report older age, HIV positive serostatus, and "never" using condoms. Internet-based recruitment was found to be more cost-effective in terms of recruitment yield than was field-based recruitment.

Virtual versus physical channel for sex networking in men having sex with men of sauna customers in the City of Hong Kong

Background

Advances in communication technology may affect networking pattern, thereby influencing the dynamics of sex partnership. The aim of the study is to explore the impacts of partner sourcing through internet and related channels on exposure risk to sexually transmitted infections (STI) including HIV.

Methods

Using venue-based sampling, a cross-sectional questionnaire survey was conducted at saunas frequented by men having sex with men (MSM) in Hong Kong. Comparison was made between MSM sourcing partners through physical venues alone versus concomitant users of physical and virtual channels, the latter referring to internet and smart-phone applications, using bivariate logistic regression.

Results

Over a 7-week study period, 299 MSM were recruited from 9 saunas. Three main types of sex partners were distinguished: steady (46.8%), regular (26.4%) and casual (96.0%) partners. Users of sauna (n = 78) were compared with concomitant users of saunas and virtual channels (n = 179) for partner sourcing. Sauna-visiting virtual channel users were younger and inclined to use selected physical venues for sourcing partners. Smart-phone users (n = 90) were not different from other internet-users in terms of age, education level and single/mixed self-identified body appearance. Classifying respondents into high risk and low risk MSM by their frequency of condom use, concomitant use of both sauna and virtual channels accounted for a higher proportion in the high risk category (71.6% vs. 58.2%, OR = 1.81, p<0.05). In virtual channel users, partner sourcing through smart-phone was not associated with a higher practice of unprotected sex.

Conclusion

MSM sauna customers commonly use virtual channels for sex partner sourcing. Unprotected sex is more prevalent in sauna customers who use virtual channel for sex partner sourcing. While the popularity of smart-phone is rising, its use is not associated with increased behavioural risk for HIV/STI transmission.

Public health challenges of the emerging HIV epidemic among men who have sex with men in China

A large-scale national survey was conducted in 2008 across 61 cities throughout China, covering over 18,000 men who have sex with men (MSM). The prevalence of human immunodeficiency virus (HIV) was 4.9% and incidence ranged from 2.6 to 5.4 per 100 person-years. The prevalence of sexually transmitted diseases ranged from 2.0% to 29.9% among MSM in different parts of China. Syphilis status, recruitment of sexual partners mainly from gay saunas, duration of MSM experience, and unprotected sex with regular male sex partners and multiple male sex partners predicted HIV seroconversion. The prevalence of consistent condom use was low during anal sex, ranging from 29.4% to 37.3%. Within this context, this paper considers the factors surrounding HIV prevention activity, and identifies a number of public health challenges which need to be considered if optimum outcomes are to be achieved. HIV prevention targeting MSM is a delayed response. The high risk associated with gay saunas and the need for steady condom supply at these venues needs urgent consideration. In addition, approximately one-third of MSM in China reported bisexual behavior, which may be attributed to sociocultural reasons and stigma against MSM. Female sex partners of MSM are seldom aware of their exposure to high risk of HIV transmission. Finally, the primitive nature of non-government organizations for HIV prevention and issues around their sustainability pose another serious challenge for the future of HIV prevention campaigns targeting MSM in China.
