Exploring the venue's role in risky sexual behavior among gay and bisexual men: an event-level analysis from a national online survey in the U.S

Impact of COVID-19 and Mpox on Sexual Practices and Disease Mitigation Strategies Over Time Among Men Who Have Sex With Men Affiliated With Collective Sex Venues

BACKGROUND

The COVID-19 pandemic and subsequent multinational mpox outbreak significantly disrupted sexual health care delivery, particularly impacting men who have sex with men (MSM). This study investigated these public health emergencies in relation to perceptions, attitudes, and sexual practices among MSM affiliated with a collective sex venue (CSV).

METHODS

Electronic surveys were sent to clientele of a high-volume CSV between June 2021 and November 2022 across 3 time periods defined as pre-Omicron, post-Omicron, and mpox. Data collection encompassed sociodemographics, health care access, sexually transmitted infection/HIV status, COVID-19 testing, and sexual behaviors. Multivariable regression analyses identified factors associated with self-reported COVID-19 testing and positivity, and mpox exposure.

RESULTS

Among 1135 responses, demographics were largely cisgender MSM and predominantly White. Increased self-reported COVID-19 positivity was associated with having more sex partners and frequenting bathhouses for meeting sex partners. Confidence in COVID-19 mitigation strategies decreased post-Omicron. Factors linked to mpox exposure included younger age, increased sex partners, sexually transmitted infection positivity, and lower confidence in mitigation strategies.

DISCUSSION

These findings underscore the intersectionality between sexual behaviors and public health responses to COVID-19 and mpox among MSM communities affiliated with a CSV. Decreased confidence in mitigation strategies and changes in sexual behaviors during public health emergencies underscore the need for targeted interventions and messaging. Collaboration between health departments and CSVs can facilitate responses to current and future public health threats and interventions.

"I Assumed that He Knows Because He's Seen My Profile": HIV Status Disclosure and Condom Use Decisions Among Men who have Sex with Men (MSM) Using Hookup Apps and Websites

In the present study, we sought to better understand how MSM make decisions about HIV disclosure when using hook-up apps/websites and how these decisions relate to condom use during app/website-facilitated sexual encounters. Semi-structured interviews were conducted with 60 MSM (30% living with HIV) who had used hook-up apps and websites to meet sexual partners within the past three months. Results demonstrated a variety of approaches to HIV status disclosure. Some men reported usually discussing HIV status, but others discussed HIV status selectively (e.g., only when asked, when a relationship became more serious). Some men reported that listing one's status in a profile precluded the need to discuss it further. Others noted that leaving an HIV status blank "hinted" at their own or others' HIV positive or negative status. These approaches were closely linked to decisions about condom use. Many men reported serosorting based on inferences or assumptions about partners' HIV status. Together, results highlighted potential gaps in communication that can lead to faulty assumptions about HIV status and subsequent serodiscordant condomless sex and suggest that interventions that promote HIV status disclosure address these potential faulty assumptions.

Social Media Communication and Network Correlates of HIV Infection and Transmission Risks Among Black Sexual Minority Men: Cross-sectional Digital Epidemiology Study

BACKGROUND

In the United States, HIV disproportionately affects Black cisgender sexual minority men (BSMM). Although epidemiological and behavioral surveillance are integral to identifying BSMM at risk of HIV infection and transmission, overreliance on self-reported data, inability to observe social contexts, and neglect of populations with limited engagement in health care systems limits their effectiveness. Digital epidemiological approaches drawing on social media data offer an opportunity to overcome these limitations by passively observing in organic settings activities, beliefs, behaviors, and moods that indicate health risks but are otherwise challenging to capture.

OBJECTIVE

The primary aim of this study was to determine whether features of Facebook communication and networks were associated with biological, behavioral, and psychological indicators of HIV infection and transmission risk.

METHODS

Facebook and survey data were collected from BSMM aged 18 to 35 years living in Chicago (N=310). Participants' Facebook posts were characterized using 4 culturally tailored topic dictionaries related to aspects of HIV protection and risk among BSMM (sexual health; substance use; sex behavior; and ballroom culture, a salient subculture in lesbian, gay, bisexual, transgender, and queer communities of color). Social network methods were used to capture structural features of BSMM's Facebook friendships (centrality, brokerage, and local clustering) and Facebook group affiliations. Multivariable regressions revealed relationships between these Facebook features and 5 ground truth indicators of HIV infection and transmission risk (sexually transmitted infection incidence, condomless sex, sex drug use, biomedical prevention, and depression).

RESULTS

Although analysis of participants' Facebook posts revealed that HIV-related topics occupied a small portion of the total messages posted by each participant, significant associations were found between the following HIV risk indicators and Facebook features: Condomless sex, including communication about sexual health (odds ratio [OR] 1.58, 95% CI 1.09-2.29), ballroom culture (OR 0.76, 95% CI 0.63-0.93), and friendship centrality (OR 0.69, 95% CI 0.52-0.92); Sex drug use, including communication about substance use (OR 1.81, 95% CI 1.17-2.79) and friendship centrality (OR 0.73, 95% CI 0.55-0.96) and brokerage (OR 0.71, 95% CI 0.51-0.99); Biomedical prevention, including communication about ballroom culture (OR 0.06, 95% CI 0.01-0.71); and Depression, including communication about sexual health (β=-0.72, 95% CI -1.42 to -0.02), ballroom culture (β=.80, 95% CI 0.27-1.34), friendship centrality (β=-0.90, 95% CI -1.60 to -0.21), and Facebook group affiliations (β=.84, 95% CI 0.25-1.43). Facebook features provided no significant explanatory value for sexually transmitted infection incidence.

CONCLUSIONS

Finding innovative strategies to detect BSMM at risk of contracting or transmitting HIV is critical to eliminating HIV disparities in this community. The findings suggest that social media data enable passive observance of social and communicative contexts that would otherwise go undetected using traditional HIV surveillance methods. As such, social media data are promising complements to more traditional data sources.

Effects of the COVID-19 Pandemic on LGBTQ+'s Sexual Behaviors in Turkey: "Everything about Sex Had Become A Black Box"

The COVID-19 pandemic has forced changes in the behavior patterns of many population groups due to restrictive measures all over the world. In this study, qualitative research method based on a phenomenological approach was used to determine the changes in the sexual behavior of a group of LGBTQ+ people living in Turkey. The COVID-19 pandemic has culminated in changes in the sexual life of LGBTQ+s. It has been determined that feelings such as the need of emotional support, loneliness, devaluation and helplessness were experienced, and quarantine and curfew restrictions were effective on sexuality and sexual behaviors. In addition, it has been determined that LGBTQ+s have changed in the standards of determining partners during the pandemic process. The use of sex toys has increased, the sensitivity toward self-care and hygiene rules has increased, the tendency to have sexual fantasies has changed, the sexual behavior of people in their social environment has changed, and the disruptions in health services have posed negative effects. It is recommended to carry out studies focusing on the sexual behavior of LGBTQ+s and to develop counseling services regarding the sexual behaviors of LGBTQ+s and the situations that occur in their sexual lives.

A Latent Profile Analysis of Online Dating Patterns Among Single Young Men Who Have Sex with Men

Despite the increased use of geosocial networking applications for finding sexual partners among young men who have sex with men (YMSM), few studies have examined the intricate patterns of online dating behaviors. In order to advance understanding of online dating patterns among YMSM, various factors, including how frequently and how much time is spent within partner-seeking sites, need to be examined concurrently. Therefore, we used latent profile analysis to identify online dating patterns and logistic regressions to examine their associations with sexual behaviors and relationship characteristics among single YMSM (N = 180; ages 18-24). We found three online dating patterns: discouraged users (N = 93, 52%), date seekers (N = 67, 37%), and instant lovers (N = 20, 11%). Discouraged users were less likely to seek sexual sensational activities, while date seekers were more likely to seek sexual sensational activities. Moreover, instant lovers were less likely to pursue committed romantic relationships, while they reported a higher number of condomless anal intercourse. Given that online dating patterns are not homogeneous, HIV prevention interventions may benefit from tailored approaches based on YMSM's different online dating profiles.

Sexual Behavior Change Among Gay and Bisexual Men During the First COVID-19 Pandemic Wave in the United States

Background

After decades of navigating HIV and other sexually transmitted infections, gay and bisexual men are responding to new and uncertain risks presented by the coronavirus (COVID-19) pandemic by adapting their sexual behavior.

Methods

This paper uses data from a national sample of 728 gay and bisexual men collected from April 10 to May 10, 2020, to examine changes to sexual behavior in response to the first wave of the pandemic in the USA. We also assess whether behavior modifications are associated with exposure to statewide public health measures, including Stay-at-Home orders.

Results

Sexual minority men report significant changes to their sexual behavior and partner selection during the first wave. Nine out of 10 men reported having either one sexual partner or no sexual partner in the last 30 days at the time of interview, a decrease compared to just before the pandemic for nearly half of men surveyed. Reporting no sexual partners in the last 30 days was significantly predicted by increased exposure to a Stay-at-Home order. Sexual minority men also reduced interactions with casual partners, increased no-contact sexual behaviors (e.g., masturbation and virtual sex), and engaged in new strategies to reduce their risks of infection from partners. HIV-positive men were particularly likely to adopt strategies including avoiding casual partners and avoiding public transportation to meet sexual partners.

Conclusion

Sexual minority men's behavior changes during the first wave may have reduced the impact of the coronavirus pandemic on their communities. Despite substantial changes in sexual behavior for most men in our sample during the initial first wave, we identify some concerns around the sustainability of certain behavioral changes over time and nondisclosure of COVID-19 symptoms to partners.

Patterns of Online and Offline Partnering, Partnership Characteristics, and Condomless Sex Among Adolescent Sexual Minority Males in the USA

Online partner-seeking among adolescent sexual minority males (ASMM) has been associated with condomless anal sex. Two hypotheses may explain this association: that online venues facilitate HIV transmission risk behavior more than offline venues (accentuation), or that individuals who tend to engage in these behaviors are more likely to seek partners online (self-selection). We examined these hypotheses in 700 13-18 year-old ASMM who completed the baseline survey of an effectiveness trial of an HIV prevention program in 2018-2020. The survey assessed demographic, sexual, and venue characteristics of male anal sex partnerships in the past 3 months. Many participants (83%) reported ≥ 1 online-met partner; most were met via sexual networking applications and were older than offline-met partners. Having met partners online, but not whether a particular partner was met online, was associated with greater odds of receptive condomless sex. Findings support the self-selection hypothesis, which has implications for HIV prevention in ASMM.

The Experience of Using Dating Applications for Sexual Hook-Ups: A Qualitative Exploration among HIV-Negative Men Who Have Sex With Men in Hong Kong

Men who have sex with men (MSM) use dating applications (apps) to explore various romantic and sexual relationships. This qualitative study aimed to describe HIV-negative MSM's experiences with app usage, the sexual activities arranged accordingly and their experiences in using dating apps to arrange sexual encounters. Thirty-one MSM who were sexually active and who used dating apps were recruited. Individual semi-structured interviews were conducted. Qualitative data were thematically analyzed to outline significant phenomena and perceptions. The factors associated with matching on apps included sex roles, human immunodeficiency virus serostatus and availability of a venue for meetup. Facilitated by these apps, diverse types of sexual encounters were arranged. Condoms were typically used for safer intercourse, except by people who were younger and inexperienced or when drugs were consumed before or during sex (chemsex). Extensive interest in non-penetrative sexual behaviors was expressed by our sample. Searching for post-exposure prophylaxis methods and/or sexual health screenings was common after exposure to risk of infections. Sexually abusive encounters were followed by changes in sex-searching habits and lowered trust in relationship formation. The results of this study are important for the development of appropriate interventions to promote safer sexual practices among HIV-negative MSM dating app users.

The Co-evolution of online social networks and syphilis incidence among young black men who have sex with men

Network contexts have been implicated in the facilitation of syphilis transmission, however little is known about the relationship between online social networks, a proxy for physical networks, and rates of syphilis infection and how they co-evolve over time. To these ends, this study explored the interdependent relationship between Facebook friendship network dynamics and rates of syphilis incidence among young Black men who have sex with men (YBMSM). Specifically, we investigated the extent to which syphilis status, as a latent profile of network members, serves as a selection mechanism of Facebook tie formation and the degree to which Facebook friendships influenced dynamics of syphilis seroconversion. Sexual health, behavioral, and social network data were collected from a cohort of YBMSM (N = 286, Mean age = 22.8) at two time points between 2013 and 2015 in Chicago, IL, USA. The interdependencies between Facebook friendship networks and syphilis infection were assessed using stochastic actor-based models for social networks and behavior. Results showed that YBMSM tended to form Facebook friendships with other YBMSM who had similar syphilis and HIV status profiles, and the hazard of contracting syphilis was likewise influenced by their Facebook friendships, albeit subtly, by being connected to infectious network members. Meanwhile, intrinsic characteristics like condomless sex, HIV status, and online partner-seeking were not associated with dynamics in syphilis incidence. These findings show that there is a mutually dependent relationship between the online network dynamics of YBMSM and rates of syphilis incidence. Findings also direct attention to network-based strategies for intervention.

Meeting Sexual Partners Online and Associations With Sexual Risk Behaviors in the Swedish Population

BACKGROUND

Online arenas may facilitate sexual encounters. However, to what extent finding sexual partners online is associated with sexual risk behavior and sexual health outcomes is still not fully explored.

METHODS

A stratified randomized population based study on sexual and reproductive health and rights of 50,000 Swedes was conducted in 2017. The final sample consisted of 14,537 women and men aged 16-84 years. We identified sexual health factors associated with finding sexual partners online and estimated prevalences thereof.

RESULTS

Having used the internet to meet sexual partners was reported by 11% (95% confidence interval: 10.1-12.3) of men and 7% (95% confidence interval: 6.0-7.4) of women and was most common among men aged 30-44 years (13.7%). After adjustment, those reporting a non-heterosexual identity were most likely to meet sexual partners online. Meeting sexual partners online was also associated with reporting several sexual risk behaviors: condomless sex with temporary partner during the past 12 months, adjusted odds ratio (AOR): 5.1 (3.8-6.8) for women and AOR: 6.0 (4.5-7.9) for men, and having had a test for sexually transmitted infections (STIs) generated a 4-fold AOR for both sexes, STI diagnosis showed a 2-fold AOR, ever having paid or given other compensation for sex AOR: 4.8 (2.7-8.8) for women and AOR: 4.2 (2.9-6.1) for men as well as ever having received money or other compensation for sex AOR: 4.0 (1.3-11.9) for women and AOR: 6.0 (2.4-15.1) for men.

CLINICAL TRANSLATION

Meeting sexual partners online was associated with sexual risk behaviors, which is of importance in tailoring sexual health interventions and STI/HIV-control activities.

STRENGTHS AND LIMITATIONS

Few studies of online sexual behaviors are based on population-based surveys of the general population with results stratified by sexual identity. However, the use of lifetime prevalence of ever having used the internet, smartphone, or app to meet sexual partners has limitations.

CONCLUSION

Meeting sexual partners online was associated with sexual risk behaviors in a randomized sample of the Swedish population, which is of importance to tailoring sexual health interventions.

Characteristics of Sex Events, Partners, and Motivations and Their Associations with HIV-Risk Behavior in a Daily Diary Study of High-Risk Men Who Have Sex with Men (MSM)

In the United States, men who have sex with men (MSM) continue to be at high-risk for HIV and other STIs, and condoms represent the most popular, affordable, and accessible method of prevention. Although a vast body of research has explored various factors associated with condom use in MSM, fewer studies have explored situation-level characteristics that affect their decisions about sex partners and condom use. Daily diary studies are well-suited to help improve our understanding of these event-level factors in detail, including the sex events themselves, partner characteristics, and motivations. As part of a larger study using ecological momentary assessment methods, high-risk MSM completed daily diary surveys about their sexual behavior on their smartphones each day for 30 days. This study explored detailed descriptive characteristics of sex events, partner characteristics, and motivations for sex and condom use, and examined whether specific aspects of these characteristics were associated with having condomless anal sex (CAS) with high-risk partners. High-risk CAS was common among MSM, with the majority of participants having met their partners online and many reporting sex the same day they met. Results showed that the odds of CAS were not higher with partners met online versus those met in other ways, but MSM were more likely to have asked online partners about their HIV status and testing history before sex. The odds of engaging in high-risk CAS was higher when MSM reported intimacy or self-assurance motives. Not having condoms readily available was a CAS motivation reported more commonly when MSM had sex with high-risk partners. Findings suggest that interventions should incorporate strategies that help MSM be safer specifically when meeting partners online and when having sex for intimacy or re-assurance. Interventions that remind MSM to carry condoms at opportune moments may also help reduce some HIV risk.

Ethical Considerations in HIV eHealth Intervention Research: Implications for Informational Risk in Recruitment, Data Maintenance, and Consent Procedures

PURPOSE OF REVIEW

Along with the benefits of eHealth HIV interventions are challenges to participant privacy and confidentiality inherent in the use of online strategies. This paper reviews current guidelines and recent publications to identify ethical issues and suggested solutions in recruitment, data management, and informed consent.

RECENT FINDINGS

Across eHealth HIV research, recruitment, data collection, and storage efforts to protect informational risk highlight the tension between the investigators' ability to protect participant confidentiality and the evolving informational risk posed by the online platforms on which they are operating. Adequately addressing these challenges requires updating technical competencies and educating participants on their own responsibilities to guard against privacy violations. Additional protections are required when interventions involve peer or community support, especially with minors. The rapid progression of technology presents challenges in solidifying best practices for future interventions. This article draws on published works describing investigator experiences to contribute to the ongoing development of guidance in this area.

Latent classes of partner-seeking venues and sexual risk among men who have sex with men in Paris, France

In France, men who have sex with men (MSM) experience the highest HIV incidence. MSM who use multiple venues such as bars and smartphone apps to find sexual partners have greater HIV and sexually transmitted infection risk than those who use a single physical or online venue. To explore the role of venues and sexual behavior on HIV risk, we used latent class analysis to highlight underlying profiles of 580 MSM in Paris, France. Three latent classes emerged: Multi-venue Users (19%), Non-serosorting App Users (49%), and Serosorting App Users (32%). Multi-venue Users had the highest probabilities of condomless receptive anal intercourse (CRAI) and condomless insertive anal intercourse (CIAI), group sex, and meeting partners at venues such as bars or online. Non-serosorting App Users had the lowest probabilities of CRAI, CIAI, and condomless serosorting. Serosorting App Users had an 87% chance of condomless serosorting. MSM reporting a pre-exposure prophylaxis history had 14 and 5 times the odds of being classified as Multi-venue Users and Serosorting App Users than Non-serosorting App Users. MSM were 3% more likely to be Multi-venue Users than Non-serosorting App Users for every one-year increase in age. Interventions addressing sexual risk behaviors among MSM in France should consider tailored risk-reduction and prevention messaging.

Is Tinder-Grindr Use Risky? Distinguishing Venue from Individuals' Behavior as Unique Predictors of Sexual Risk

Geosocial networking apps (GSN; e.g., Tinder, Grindr) have rapidly increased in popularity, showing associations with greater sexual risk-taking. This study sought to distinguish between risks associated with intensive partner-seeking (i.e., individuals seeking out casual sex frequently across many venues) and risks associated with specific venues (e.g., GSNs, dating websites, offline activities). Expanding upon a literature predominantly focused on the population of men who have sex with men (MSM), we recruited a broader range of sexual identities. A convenience sample of 3180 participants from the U.S. (18-75 years old, 69% female, 75% Caucasian, 68% heterosexual) completed an anonymous, cross-sectional online survey. Logistic regressions yielded adjusted odds ratios highlighting the unique links between each predictor and sexual risk-taking. MSM/WSW indicators, quantity of partner-seeking and specific venues-particularly GSN use-emerged as robust predictors of sexual risk, increasing the odds of reporting all six outcomes examined: (1) having three or more sex partners in the last year, (2) having hookups in the last 2 months, (3) having hookups involving alcohol or (4) drug use, (5) condomless sexual activity with new partners in the last 2 months, and (6) ever having had a sexually transmitted infection. Although a large portion of risk originated from the proclivities of the individuals seeking casual sex, both online and offline methods of partner-seeking also contributed significant risk, suggesting that specific venues like GSN apps could be used as methods of targeting higher-risk behaviors. The results also highlight the importance of moving beyond MSM when addressing sexual risk.

Sex-on-premise venues, associated risk behaviors, and attitudes toward venue-based HIV testing among men who have sex with men in Lima, Perú

BACKGROUND

In Perú, HIV disproportionately affects men who have sex with men (MSM). Despite widespread access to treatment, the high rate of new HIV infections has remained unchanged over the last decade. Low knowledge of HIV status associated with late diagnosis is a key factor underlying the high HIV incidence observed in this setting, creating conditions for efficient onward transmission. Improving access to HIV testing and prevention services for those at highest risk is an important public health priority. Sex-on-premise venues (SOPVs) - saunas, sex clubs, pornographic movie theaters, hourly hotels, and bars/discos with areas where sex is permitted - may be opportune sites for outreach; however, further research on SOPVs and the populations who frequent them is needed to inform such efforts.

METHODS

We conducted a cross-sectional online survey of adult MSM in Lima, Perú to evaluate patterns of SOPV attendance, associated sexual risk behaviors, and attitudes toward SOPV-based interventions. Participants were recruited through outreach to social media networks affiliated with local LGBTQ-aligned community groups. Our primary analytic objective was to estimate the association of HIV-related sexual risk behaviors and SOPV attendance. Additionally, we performed exploratory analyses to describe risk behavior stratified by SOPV category and to examine the relationship between SOPV attendance and the use of online platforms to meet sex partners.

RESULTS

Overall, 389 MSM completed the survey from November 2018 through May 2019, of whom 68% reported attending an SOPV in the last 3 months. SOPV attendance was associated with multiple sexual risk behaviors, including transactional sex, group sex, substance use around the time of sex, and higher number of partners. Over two thirds of SOPV attendees indicated they would accept HIV testing if offered at SOPVs.

CONCLUSIONS

SOPV attendance was common among MSM in Lima who participated in our survey, and SOPV attendees reported significantly greater engagement in sexual risk behaviors related to HIV transmission. Attitudes toward hypothetical SOPV-based interventions were generally favorable. These findings suggest that outreach at SOPVs may be an effective mechanism for reaching a particularly high-risk sub-population of MSM in Perú to deliver targeted HIV testing and prevention interventions.

Sexualized drug use in virtual space: A scoping review of how gay, bisexual and other men who have sex with men interact online

The purpose of this article is to review the scope of the current literature on sexualized drug use (SDU) among gay, bisexual and other men who have sex with men (GBMSM), particularly in online spaces. Over the last decade, there has been a rapid emergence of online venues for GBMSM to interact for sexual purposes. These spaces have also been infused with various substances that influence or shape the sexual interactions among GBMSM. Employing a scoping review methodology, we explored the interplay between GBMSM, SDU, and online dating and hookup apps. This scoping review presents four themes emerging from the literature: the connection between social networking apps (SNAs) and SDU, the planning and coordination of sex parties, accessing drugs through SNAs, and the coded language that emerges on SNAs. These findings synthesize the important relationship between GBMSM and SDUs, and identify the implications for health promotion.

Prevalence of sexually transmissible infections and HIV in men attending sex-on-premises venues in Australia: a systematic review and meta-analysis of observational studies

Background In Australia, men who have sex with men (MSM) have high rates sexually transmissible infections (STIs) and sex-on-premises venue (SOPV) patrons are at risk. This paper assesses Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), syphilis and HIV prevalence in men tested at Australian SOPVs and describes testing services.

METHODS

EMBASE, Medline, PubMed and international conference proceedings were searched for articles reporting on-site SOPV testing between 1 January 2000 and 31 January 2017. Meta-analysis calculated pooled prevalence estimates of STIs by anatomical site.

RESULTS

Twelve cross-sectional studies were identified. Most (8/12) were local sexual health clinics (SHC) outreach services. Participants' mean age was 41.1 years (95% confidence interval (CI) 37.0-43.3; range 17 to 84 years). Testing included CT and NG (9/12), HIV (8/12) and syphilis (5/12). CT and NG prevalence overall summary estimates were 3.4% (95% CI 1.9-5.2%, I2 = 88.7%, P < 0.01) and 1.3% (95% CI 0.7-2.2%, I2 = 75.5%, P < 0.01) respectively. CT and NG prevalence was highest in the ano-rectum and oro-pharynx respectively. The HIV and syphilis pooled estimates were 2.3% (95% CI 1.6-2.9%, I2 = 93.1%, P < 0.01) and 3.2% (95% CI 1.8-4.6%, I2 = 72.8%, P < 0.01) respectively. Participation rate varied.

CONCLUSION

This review examines HIV and STI testing in Australian SOPVs before HIV pre-exposure prophylaxis (PrEP). Findings indicate a high prevalence of STIs. PrEP use and resultant condomless sex may influence STI prevalence. Further research is required to determine the effect of PrEP on the STI prevalence among SOPV patrons.

The Gay Community Involvement Index: An Exploratory Factor Analysis and Initial Validation of a New Measure of Gay Community Involvement

This article details initial measure development, exploratory factor analysis, and preliminary validation of the Gay Community Involvement Index (GCII) across two studies. Previous research on gay community involvement has relied on measures that do not distinguish between distinct ways in which men may be involved in the gay community (e.g., going to bars and clubs vs. advocating for political issues). The GCII is a new multidimensional measure of the type and intensity of participation in a variety of activities within the gay community. Exploratory factor analysis suggested four subscales: Community Activities, Nightlife, Media, and Political Activism. We report strong evidence for internal consistency within subscale scores, as well as both convergent and discriminant validity for subscale scores. This measure may help those researching gay men's health and well-being better understand the impact of different types of community involvement on health and psychosocial outcomes.

A theoretical examination using governmentality to understand gay men’s risk and sexual behaviours

This article explores the link between Foucault’s (1991) governmentality theory, specifically as it relates to gay men’s sexual practices and perceptions of HIV risk. Foucault’s (1991) theory of governmentality elucidates the means through which individual behaviours and norms (at a micro level) are governed through the production of disciplinary norms and structures that are instantiated at a broader structural and institutional level (the macro-level). Foucauldian theoretical conversations pertaining to what is meant by conceptions and definitions of HIV/STI risk are furthered through this paper’s theoretical contributions as they relate to gay men. From a Foucauldian perspective, we assess how gay men may alter or monitor their sexual practices through governmental scripts produced at a state level and manifested through micro- and macro-level behavioural and ideological shifts based on dominant socio-sexual norms. A model of the interrelationship between governmentality, scripting, the micro/macro levels, and the situation-specific is presented for future consideration when examining gay men’s sexual practices. Historical oppression and segregation of gay men are considered when exploring these theories from a critical social scientific lens.

Identifying Basic Classes of Sexual Orientation with Latent Profile Analysis: Developing the Multivariate Sexual Orientation Classification System

Despite considerable progress, research on sexual minorities has been hindered by a lack of clarity and consistency in defining sexual minority groups. Further, despite recent recommendations to assess the three main dimensions of sexual orientation-identity, behavior, and attraction-it remains unclear how best to integrate such multivariate information to define discrete sexual orientation groups, particularly when identity and behavior fail to match. The current study used a data-driven approach to identify a parsimonious set of sexual orientation classes. Latent profile analysis (LPA) was run within a large (N = 3182) and sexually diverse sample, using dimensions of sexual identity, behavior, and attraction as predictors. LPAs supported four fundamental sexual orientation classes not only in the overall sample, but also when conducted separately in men (n = 980) and women (n = 2175): heterosexual, homosexual, bisexual, and heteroflexible (a class representing individuals who self-identify as heterosexual or mostly heterosexual but report moderate same-sex sexual behavior and attraction). Heterosexuals reported the highest levels of psychological functioning and lowest risk behaviors. Homosexuals showed similarly high levels of psychological functioning to heterosexuals, but higher levels of risk behaviors. Bisexuals and heteroflexibles showed similarly low levels of psychological functioning and high risk taking. To facilitate applications of this classification approach, the study developed the Multivariate Sexual Orientation Classification System, reproducing the four LPA groups with 97% accuracy (kappa = .95) using just two items. Implications of this classification approach are discussed.

Misclassification of sexual health risks in a self-identified low risk cohort of men who have sex with men (MSM) enrolled in a community based PrEP program

The CDC recommends PrEP for MSM at substantial risk of HIV acquisition, leaving clinicians unsure whether to prescribe PrEP to MSM who do not disclose HIV risk factors. A longitudinal cohort of MSM requesting PrEP despite reporting during a clinical visit either 100% condom use or participation in oral sex only and no other risk factors was followed over 13 months at a community clinic in San Francisco to assess the accuracy of their HIV risk perception. Participants completed a sexual and substance use behavior questionnaire at baseline, outside of the clinical visit and were followed by quarterly HIV/STI testing and condom use change questionnaires. Condomless sex increased from 0% at baseline to 12% at month 1, peaked at 34% at month 7, and then decreased again to 8% at month 13. Rates of pharyngeal GC/CT varied from 7% at baseline to 12% at month 13, while rectal GC/CT decreased from 6% at baseline to 0% at month 13. The rate of syphilis was 1% both at baseline and at month 13, however, 11% and 15% of clients tested positive for syphilis at months 1 and 7 respectively.

Does HIV Pre-Exposure Prophylaxis Modify the Effect of Partnership Characteristics on Condom Use? A Cross-Sectional Study of Sexual Partnerships Among Men Who Have Sex with Men in San Francisco, California

Increasing rates of sexually transmitted infections (STIs) in the United States among men who have sex with men (MSM) have raised concerns that pre-exposure prophylaxis (PrEP) has been associated with higher engagement in condomless anal intercourse (CAI). While partnership characteristics have previously been found to influence condom use, the extent to which PrEP use may modify their effect on CAI remains unknown. A secondary analysis of 535 sexual partnerships from a cross-sectional study in San Francisco was conducted to evaluate interactions between PrEP use and partnership characteristics on CAI. Bivariate and multivariate generalized estimating equation (GEE) logistic regression models were used to estimate relative measures of association, adjusted for confounding by seroconcordance and partnership type, as well as account for repeated partnerships per respondent. Partnerships where both partners used biomedical prevention had significantly greater odds of CAI [odds ratio (OR) = 5.19, 95% confidence interval (CI): 2.27-11.9] compared to those where only one partner used biomedical prevention, while those where neither partner used biomedical prevention had significantly lower odds of CAI (OR = 0.61, 95% CI: 0.40-0.93). There was no significant association between meeting place (online vs. offline) and sexual risk taking (OR = 1.03, p = 0.894). Having one partner disclose their HIV status (compared to neither partner having disclosed) was associated with significantly higher odds of CAI among partnerships of PrEP-using MSM [adjusted OR (aOR) = 5.28, 95% CI: 1.91-14.61], while the association was not significant among the partnerships of non-PrEP-using MSM (aOR = 1.29, 95% CI: 0.75-2.21). Differences in condom use among MSM using PrEP may not be well explained by differences in the effect of partnership characteristics. MSM using PrEP appear to commonly practice biomedical matching and high engagement in CAI with other biomedical prevention users, which could indicate relatively concentrated sexual networks and partly explain their disproportionate risk for STIs. Future studies should further investigate biomedical matching to develop interventions that further promote the sexual health of those using PrEP.

Stress and substance use among sexual and gender minority individuals across the lifespan

Sexual and gender minority (SGM) individuals face marked disparities in substance use. The present narrative review explores research on substance use in SGM communities using a minority stress theory lens. We define the SGM population and minority stress, and explore stresses and substance use disparities in adolescence, adulthood, and older age. Though research on this topic is beginning to highlight the relationship between stress and substance use for SGM individuals, more work is needed on older SGM populations and in translating research findings to effective interventions.

Rethinking Risk, Culture, and Intervention in Collective Sex Environments

This article provides a narrative overview of research on HIV/STI risk and collective sexual behavior based on an inclusive analysis of research on environments where people gather for sexual activity-sex clubs, swingers' clubs, bathhouses, parks, private sex parties, etc. The aim is to analyze how collective sex has been approached across disciplines to promote conversation across paradigms and suggest new lines of inquiry. Attention to context-such as the location of sex-was a necessary redress to universalizing models of sexual risk-taking behavior, leading to insights rooted in the particularities of each environment and its users. However, the identification of ever more precise risk groups or environmental idiosyncrasies eventually becomes theoretically restrictive, leading to an overestimation of the uniqueness of sexual enclaves, and of the difference between any given enclave and the broader social milieu. Using a theoretical framework of transgression to interpret the interdisciplinary literature, similarities in the spatial and social organization of collective sex environments are identified. Insights generated from this complementary perspective are then applied to understandings of collective sex: first, the example of male-female (MF) "swingers" is used to illustrate the need to establish, rather than assume, the distinctiveness of each non-normative sexual enclave, and to broaden the conceptualization of context; second, questions are raised about the practicality of interventions in collective sex environments. Finally, new lines of intellectual inquiry are suggested to shed light not just on collective sex but on sociosexual issues more generally, such as increasing protective sexual health behavior or negotiating consent in sexual encounters.

The Association between Use of Online Social Networks to Find Sex Partners and Sexually Transmitted Infection Diagnosis among Young Men Who Have Sex with Men and Transgender Women Living with HIV

We conducted a cross-sectional analysis of baseline data from the Adolescent Trials Network for HIV/AIDS Interventions to examine the association between the use of social media sites to find sex partners and recent diagnosis of sexually transmitted infections (STIs) among 13- to 24-year-old men who have sex with men and transgender women living with HIV. We used linear regression to determine the relationship between the number of STIs and the number of social media sites used to find sex partners with each type of sex act included in the analysis. Secondary analyses substituted frequency of social media site use for number of social media sites. Among 741 participants, for every 1 social media account used to find sex partners, there was a 2.53% (95% confidence interval: 0.28-5.54) increase in STIs. This association was mediated through condomless receptive anal intercourse or condomless insertive anal intercourse but not barrierless oral intercourse. Similar but attenuated associations were found when frequency of social media site use was substituted for number of social media sites. Future research should examine innovative interventions on these social media sites with respect for its users.

Perceptions of Needs, Assets, and Priorities Among Black Men Who Have Sex With Men With HIV: Community-Driven Actions and Impacts of a Participatory Photovoice Process

Black men who have sex with men (MSM) with HIV experience significant health inequities and poorer health outcomes compared with other persons with HIV. The primary aims of this study were to describe the needs, assets, and priorities of Black MSM with HIV who live in the Southern United States and identify actions to improve their health using photovoice. Photovoice, a participatory, collaborative research methodology that combines documentary photography with group discussion, was conducted with six Black MSM with HIV. From the photographs and discussions, primary themes of discrimination and rejection, lack of mental health services, coping strategies to reduce stress, sources of acceptance and support, and future aspirations emerged. After the photographs were taken and discussed, the participants hosted a photo exhibition and community forum for the public. Here, 37 community attendees and influential advocates collaborated with the participants to identify 12 actions to address the men's identified needs, assets, and priorities. These included making structural changes in the legal and medical systems, encouraging dialogue to eliminate multiple forms of stigma and racism, and advocating for comprehensive care for persons with HIV. As a secondary aim, the impacts of photovoice were assessed. Participants reported enjoying photovoice and found it meaningful. Results suggest that in addition to cultivating rich community-based knowledge, photovoice may result in positive changes for Black MSM with HIV.

HIV Prevention and Sex Behaviors as Organizing Mechanisms in a Facebook Group Affiliation Network Among Young Black Men Who Have Sex with Men

Online social networking sites (SNS)-the Internet-based platforms that enable connection and communication between users-are increasingly salient social environments for young adults and, consequently, offer tremendous opportunity for HIV behavioral research and intervention among vulnerable populations like young men who have sex with men (YMSM). Drawing from a cohort of 525 young Black MSM (YBMSM) living in Chicago, IL, USA April 2014-May 2015, we conducted social network analysis, estimating an exponential random graph model (ERGM) to model YBMSM's group affiliations on Facebook in relation to their sex behaviors and HIV prevention traits. A group's privacy setting-public, closed, or secret-was also modeled as a potential moderator of that relationship. Findings reveal that HIV positive individuals were more likely to affiliate with Facebook groups, while those who engaged in group sex were less likely to do so. When it came to the privacy of groups, we learned that HIV positive individuals tended not to belong to groups with greater privacy (e.g., closed and secret groups), while individuals who engaged in group sex and those who engaged in regular HIV testing were more likely to belong to those groups. Results also showed that individuals who engaged in condomless sex showed significant signs of clustering around the same set of groups. HIV positive individuals, on the other hand, were significantly less likely to demonstrate clustering. Implications for interventions and future research are discussed.

Prevalence of and Factors Associated with the Use of HIV Serosorting and Other Biomedical Prevention Strategies Among Men Who Have Sex with Men in a US Nationwide Survey

PrEP and treatment-as-prevention (TasP) are biomedical strategies to reduce HIV transmission. Some men who have sex with men (MSM) are combining biomedical strategies with HIV serosorting-termed "biomed matching" when both partners are either on PrEP or TasP, or "biomed sorting" when one partner is using PrEP and the other TasP. Nevertheless, there is limited data on the extent of biomed matching/sorting in large geographically diverse samples. In 2016-2017, 5021 MSM from across the US were surveyed about their HIV status and HIV viral load/PrEP use, as well as that of their recent casual male partners. For each participant, we calculated the proportion of his partners who were (1) HIV-positive and undetectable, (2) HIV-positive and detectable/unknown, (3) HIV unknown/undiscussed, (4) HIV-negative on PrEP, (5) HIV-negative, not on PrEP. In total, 66.6% (n = 3346) of participants were HIV-negative and not on PrEP, 11.9% (n = 599) on PrEP, 14.1% (n = 707) HIV-positive and undetectable, 1.1% (n = 55) HIV-positive and viral load detectable/unknown, and 6.2% (n = 313) HIV unsure/unknown. A participant's own HIV and PrEP status/was significantly associated with that of his partners (all p < 0.001), evincing evidence of both serosorting and biomed matching. Among men on PrEP and those who were HIV-undetectable, there was also some evidence to suggest these participants dually engaged in biomed matching as well as biomed sorting. We found evidence of biomed matching and sorting, which may compound its effectiveness for those using it (i.e., both partners bring biomedical protection). Unintended consequences of biomed matching/sorting include that men not using a biomedical strategy may be less likely to benefit from a partner's use of the strategy-potentially further driving disparities in HIV infections. Public health campaigns might be well served to highlight not only the benefits that biomedical HIV prevention strategies provide for their users (e.g., "being on PrEP protects me from getting HIV"), but also the benefits that a user brings to his partners (e.g., "my use of PrEP means my partners won't get HIV"), and the benefits of being with a partner who is using a biomedical strategy (e.g., "my partner's use of PrEP/TasP protects me from HIV").

A Network Analysis of Sexually Transmitted Diseases and Online Hookup Sites Among Men Who Have Sex With Men

BACKGROUND

Sexually transmitted diseases (STDs) are increasing among gay, bisexual, and other men who have sex with men (MSM). Little is known about the use of websites and mobile phone applications to meet sexual partners ("hookup sites") and association with STD diagnoses.

METHODS

We performed a demographic and behavioral assessment of 415 MSM presenting to the Rhode Island STD clinic. Bivariate and multivariable analyses assessed associations between using hookup sites and testing positive for syphilis, gonorrhea, or chlamydia. Venue-based affiliation networks were created to evaluate hookup sites and their association with STD diagnoses.

RESULTS

Among 415 MSM, 78% reported meeting a partner online in the last 12 months, and 25% tested positive for at least one STD. Men who met partners online were more likely to be white (67% vs. 54%, P = 0.03) and have more than 10 lifetime partners (87% vs. 58%, P < 0.05). The most commonly used hookup sites included Grindr (78%), Scruff (35%), and Tinder (22%). In the multivariable analysis, only Scruff use was associated with testing positive for an STD (odds ratio, 2.28; 95% confidence interval, 1.09-4.94). However, among men who met partners online, 75% of men diagnosed as having an STD had met a sexual partner on Grindr, including 100% of those who were diagnosed as having gonorrhea.

CONCLUSIONS

Use of hookup sites was nearly ubiquitous among MSM undergoing STD screening. Specific hookup sites were significantly associated with STD diagnoses among MSM. Greater efforts are needed to promote STD screening and prevention among MSM who meet partners online.

An Event-Level Analysis of Condomless Anal Intercourse with a HIV-Discordant or HIV Status-Unknown Partner Among Black Men Who Have Sex with Men from a Multi-site Study

Despite the high HIV incidence and prevalence among black men who have sex with men (BMSM), little research has examined partner characteristics, partner seeking venue, sexual position, substance use, and sexual risk behavior at the sex event-level among BMSM. Using the baseline data from a multi-site study of 807 BMSM stratified by their HIV status, the goal of this study was to conduct a detailed event-level analysis of 1577 male anal sex events to assess the factors associated with condomless anal intercourse (CLAI) with a HIV-discordant or HIV status-unknown partner. We found CLAI with an HIV-discordant or unknown HIV status partner among HIV-negative BMSM was negatively associated with having sex with a main partner, and was positively associated with taking both receptive and insertive sexual positions during sex. As compared to a sex partner met at bar, night club or dance club, HIV-positive BMSM were less likely to engage in CLAI with HIV-discordant and unknown HIV status partner met at party or friend's house or at community organizations. HIV-positive BMSM had lower odds of engaging in CLAI with HIV-discordant and unknown HIV status partner if they had insertive sexual position or both receptive and insertive sexual positions. These results underscore the importance of delineating unique sex event-level factors associated with sexual risk behavior depending on individuals' HIV status. Our findings suggest event-level partner characteristics, sexual position, and partner seeking venues may contribute to disparities in HIV incidence.

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.

Correlates of Serosorting and Knowledge of Sexual Partner's HIV Status Among Men Who have Sex with Men in Ukraine

Ukraine has among the highest rates of newly diagnosed HIV infections in the WHO European region. Men who have sex with men (MSM) is the least studied group in the context of the HIV epidemics in Ukraine. The present paper aims to estimate the prevalence and correlates of knowledge of sexual partner's HIV status and potentially discordant anal intercourse (failure to serosort) among MSM. Data of the cross-sectional study among 8100 MSM in Ukraine in 2013 were used for this analysis. Less than half of the participants (42.5%) reported that they knew the HIV serostatus of their most recent male sexual partner, and about 13% of participants reported failure to serosort during their most recent anal sexual intercourse with a male partner. Targeted interventions can be implemented to increase knowledge about sexual partner's HIV status, both among HIV-negative and HIV-positive MSM, to reduce the risk of HIV acquisition and transmission.

Using a "Positive Deviance" Framework to Discover Adaptive Risk Reduction Behaviors Among High-Risk HIV Negative Black Men Who Have Sex with Men

Despite the high incidence of HIV among young Black MSM in the United States and engagement in high risk behaviors, many men in this group avoid infection. This suggests that some men may engage in systematic risk reduction behaviors when not always using condoms or abstaining from substances. Using a "positive deviance" framework, we conducted qualitative interviews with HIV-negative, Black MSM between 25 and 35 who reported unprotected anal sex and drug use in the past six months or current heavy drinking (N = 29) to discover behaviors that could facilitate remaining HIV-uninfected. Findings showed that MSM who remain HIV negative despite continuing to engage in high-risk behaviors may be engaging in adaptive risk reduction behaviors that, through successive decisions and advance planning along the timeline to a sexual event, could lead to increased condom use, avoidance or delay of a risky sexual event, or reduction of HIV positive partners.

Repeated Measures Analysis of Alcohol Patterns among Gay and Bisexual Men in the Momentum Health Study

BACKGROUND

This study analyzed repeated study visits (n = 2,624) of 693 gay and bisexual men (GBM) in the Momentum Health Study from July, 2012 to June, 2015. Based on recent cross-sectional analyses, we hypothesized that over the study period: (1) hazardous drinking levels would remain high, (2) GBM classified as Hazardous Drinkers will be consistently associated with high risk sex, and (3) GBM classified as Always Hazardous Drinkers differ significantly from Sometimes Hazardous Drinkers.

METHODS

AUDIT classified participants as Non-Hazardous Drinkers or Hazardous Drinkers, the Cochran-Mantel-Haenszel Test assessed hazardous drinking trends, and Generalized Estimating Equations (GEE) analysis identified Hazardous Drinking covariates. Logistic regression analysis of participants with at least two study visits (575) compared those who were Sometimes Hazardous Drinkers (n = 171) with Always Hazardous Drinkers (n = 129).

RESULTS

At baseline 40% of participants were Hazardous Drinkers, but there was a significant decline in hazardous drinking by visit and Hazardous Drinkers were not significantly associated with high risk sex. Always Hazardous Drinkers had significantly more high risk sex and gay bar attendance, but less often sought Internet sex partners compared to Sometimes Hazardous Drinkers.

CONCLUSIONS

Analyses did not support the first two hypotheses, but distinguishing between Always and Sometimes Hazardous drinkers identified a young GBM subgroup associated with significantly higher levels of high risk sex and social support measures. These results suggest interventions programs based on Social Norms Theory, which predicts peer norms among youth are important factors in regulating drinking patterns, may be effective for these men.

Swipe Right: Dating Website and App Use Among Men Who Have Sex With Men

This study explored the frequency of dating website and app usage among MSM to understand sub-group differences in use. Web-based survey data (N = 3105) were analyzed to assess the use of dating websites and apps. More than half (55.7%) of MSM in this sample were frequent users of dating websites and apps. Two-thirds (66.7%) of frequent users had casual partners only in the past 12 months and reported a high average number of casual sexual partners in the past 12 months (Mdn = 5.0) compared to never users (Mdn = 0.0; χ ²(2) = 734.94, adj. p < .001). The most frequently used dating website or app was Grindr, with 60.2% of the sample reporting some or frequent use. Adam4Adam (23.5%), Jack'd (18.9%) and Scruff (18.7%) were also frequently used. Dating websites and apps may be effective channels to reach a diverse group of MSM with HIV prevention messages.

HIV transmission and pre-exposure prophylaxis in a high risk MSM population: A simulation study of location-based selection of sexual partners

OBJECTIVE

In France, indications for pre-exposure prophylaxis (PrEP) for HIV prevention are based on individual-level risk factors for HIV infection. However, the risk of HIV infection may also depend on characteristics of sexual partnerships. Here we study how place-based selection of partners change transmission and the overall efficiency of PrEP.

METHODS

We used the PREVAGAY survey of sexual behavior and HIV serostatus in men who have sex with men (MSM) in a Parisian district to look for associations between sexual network characteristics and HIV infection. We then simulated HIV transmission in a high-risk MSM population. We used information about venues visited to meet casual sexual partners (clubs, backrooms or saunas) to define sexual networks. We then simulated HIV transmission in these networks and assessed the impact of PrEP in this population.

RESULTS

In the PREVAGAY study, we found that HIV serostatus changed with the type of venues visited, in addition to other individual risk factors. In simulations, we found similar differences in HIV incidence when the choice of venues visited was not random. The use of PrEP allowed reducing incidence, irrespective of the venues visited by PrEP users. However, with the same amount of PrEP, the number of infections adverted could almost double depending on network structure and venues visited by PrEP users.

CONCLUSION

This study shows that characteristics of the sexual network structure can strongly impact the effectiveness of PrEP interventions. These should be considered further to refine individual risk assessment and maximize the effect of individual-based prevention policies.

Do Subjective Alcohol Screening Tools Correlate with Biomarkers Among High-Risk Transgender Women and Men Who Have Sex with Men in Lima, Peru?

Alcohol abuse can influence sexual risk behavior; however, its measurement is not straightforward. This study compared self-reported alcohol use, via the AUDIT and CAGE, with levels of phosphatidylethanol (Peth), a phospholipid biomarker that forms with chronic, heavy drinking, among high-risk MSM and TW in Lima, Peru. Chi square, Fisher's exact, Wilcoxon ranksum tests compared the instruments. Receiver operating curves determined sensitivity and specificity of the self-reported measures. Among 69 MSM and 17 TW, PEth was positive for 86% (95% CI 77-93%) of participants, while 67% reported binge-drinking in the last 2 weeks. The AUDIT classified 25% as hazardous drinkers while CAGE identified 6% as problem drinkers. Self-reported binge drinking was more sensitive than the AUDIT for PEth positivity (71% vs. 27%, p = 0.022). Among high-risk MSM and TW in Lima, validated, self-report measures of alcohol abuse underestimated biological measures. Further research correlating bio-markers and self-reported alcohol abuse measures is needed.

Online Sex-Seeking Among Men who have Sex with Men in Nigeria: Implications for Online Intervention

The TRUST/RV368 project was undertaken to apply innovative strategies to engage Nigerian MSM into HIV care. In this analysis we evaluate characteristics of online sex-seekers from the TRUST/RV368 cohort of 1370 MSM in Abuja and Lagos. Logistic regression and generalized estimating equation models were used to assess associations with online sex-seeking. Online sex-seeking (n = 843, 61.5 %) was associated with participation in MSM community activities, larger social and sexual networks, and higher levels of sexual behavior stigma. In addition, online sex-seeking was associated with testing positive for HIV at a follow-up visit [adjusted odds ratio (aOR) = 2.02, 95 % confidence interval (CI) = 1.37, 2.98)] among those who were unaware of or not living with HIV at baseline. Across visits, online sex-seekers were marginally more likely to test positive for chlamydia/gonorrhea (aOR 1.28, 95 % CI 0.99, 1.64). Online sex-seekers in Nigeria are at increased risk for HIV/STIs but may not be benefiting from Internet-based risk reduction opportunities.

Sex Behaviors as Social Cues Motivating Social Venue Patronage Among Young Black Men Who Have Sex with Men

HIV prevention programs often focus on the physical social venues where men who have sex with men (MSM) frequent as sites where sex behaviors are assumed to be practiced and risk is conferred. But, how exactly these behaviors influence venue patronage is not well understood. In this study, we present a two-mode network analysis that determines the extent that three types of sex behaviors-condomless sex, sex-drug use, and group sex-influence the patronage of different types of social venues among a population sample of young Black MSM (YBMSM) (N = 623). A network analytic technique called exponential random graph modeling was used in a proof of concept analysis to verify how each sex behavior increases the likelihood of a venue patronage tie when estimated as either: (1) an attribute of an individual only and/or (2) a shared attribute between an individual and his peers. Findings reveal that sex behaviors, when modeled only as attributes possessed by focal individuals, were no more or less likely to affect choices to visit social venues. However, when the sex behaviors of peers were also taken into consideration, we learn that individuals were statistically more likely in all three behavioral conditions to go places that attracted other MSM who practiced the same behaviors. This demonstrates that social venues can function as intermediary contexts in which relationships can form between individuals that have greater risk potential given the venues attraction to people who share the same risk tendencies. As such, structuring interventions around these settings can be an effective way to capture the attention of YBMSM and engage them in HIV prevention.

Sexual Partner Concurrency Among Partners Reported by MSM with Recent HIV Infection

We examined concurrency among sexual partners reported by men who have sex with men (MSM) with recent (acute or early) HIV infection in San Diego, California (2002-2015). Partners overlapping in time in the past 3 months were considered concurrent. Logistic generalized linear mixed models were used to identify factors associated with concurrency at the partner-level. 56% (388/699) of partners were concurrent to ≥1 other partner. The odds of concurrency were higher among partners >10 years younger than the participant (vs. within 10 years of age) [adjusted odds ratio (AOR) = 2.22, 95% confidence interval (CI) 1.09-4.52], longer term partners (AOR per month = 1.02, 95% CI 1.01-1.03), and partners met online (AOR = 1.56, 95% CI 0.98-2.48). Concurrency is common among partners of recently HIV-infected MSM. Tailored HIV prevention strategies for MSM with older partners, longer term partners, and partners met online may help minimize the potential impact of concurrency on HIV transmission.

Cruising Venues as a Context for HIV Risky Behavior Among Men Who Have Sex With Men

We examined differences in sexual risk behaviors, HIV prevalence, and demographic characteristics between men who have sex with men (MSM) who visit different types of venues to meet sexual partners, and identified correlates of high-risk behaviors. A cross-sectional behavioral survey was conducted with a venue-based sample of 1011 MSM in Portugal. Overall, 36.3 % of MSM usually visit cruising venues to meet sexual partners (63.7 % only visit social gay venues). Cruising venues' visitors reported higher HIV prevalence (14.6 % [95 % CI 11-18 %] vs. 5.5 % [95 % CI 4-7 %]). Visiting cruising venues was more likely among those older, reporting high number of male sexual partners, group sex, and unprotected anal sex with a partner whose HIV status was unknown. Cruising venues play an important role in increasing risk of HIV transmission among MSM who frequent them. Venue-focused behavioral interventions that promote healthy sexual behaviors are needed.

Online Partner Seeking and Sexual Risk Among HIV+ Gay and Bisexual Men: A Dialectical Perspective

For almost two decades, researchers have explored the relationship between online partner seeking (OPS) and HIV/STI transmission risk behavior among men who have sex with men (MSM), including gay- and bisexual-identified men. A dichotomy has emerged with some findings that OPS is associated with greater sexual risk behavior, and a sparser but emerging literature that men may use OPS for sexual risk reduction. This study examined the association between proportion of partners met online and sexual risk behavior in a sample of 170 HIV-positive gay- and bisexual-identified men. Participants completed assessments including psychosocial factors and a comprehensive assessment of sexual behavior, including total number of male partners, and condomless insertive and receptive anal sex with HIV-negative/unknown serostatus partners or HIV-positive male partners. Our findings support taking a dialectical stance and indicate that OPS may impact risk differently given different individual and contextual circumstances.

Sexual Venue Choice and Sexual Risk-Taking Among Substance-Using Men Who have Sex with Men

Commercial sex venues (CSVs) and public sex environments (PSEs) offer men who have sex with men (MSM) sexual privacy and anonymity. Sociodemographic characteristics (e.g., race/ethnicity, sexual identity, age, HIV status) are correlated with individuals' choice of sexual venue, potentially suggesting environmental associations with both sociodemographics and sexual risk. From March 2005 through March 2012, 1298 substance-using MSM provided information on their most recent sexual encounter; iterative logit models estimated associations between sociodemographics and sexual venue, and/or whether sexual venue was associated with sexual risk-taking while controlling for sociodemographics. More than a third of participants' most recent sexual encounters took place in either a PSE (23.0%) or a CSV (11.3%); anonymous, HIV-serodiscordant, and/or sex while on methamphetamine and/or marijuana was significantly more likely to occur in CSVs/PSEs than in a private location, even when controlling for sociodemographics. Findings demonstrate that socioenvironmental factors were associated with sexual risk-taking among high-risk, urban MSM.

HIV Testing Among Internet-Using MSM in the United States: Systematic Review

Regular HIV testing enables early identification and treatment of HIV among at-risk men who have sex with men (MSM). Characterizing HIV testing needs for Internet-using MSM informs development of Internet-facilitated testing interventions. In this systematic review we analyze HIV testing patterns among Internet-using MSM in the United States who report, through participation in an online study or survey, their HIV status as negative or unknown and identify demographic or behavioral risk factors associated with testing. We systematically searched multiple electronic databases for relevant English-language articles published between January 1, 2005 and December 16, 2014. Using meta-analysis, we summarized the proportion of Internet-using MSM who had ever tested for HIV and the proportion who tested in the 12 months preceding participation in the online study or survey. We also identified factors predictive of these outcomes using meta-regression and narrative synthesis. Thirty-two studies that enrolled 83,186 MSM met our inclusion criteria. Among the studies reporting data for each outcome, 85 % (95 % CI 82-87 %) of participants had ever tested, and 58 % (95 % CI 53-63 %) had tested in the year preceding enrollment in the study, among those for whom those data were reported. Age over 30 years, at least a college education, use of drugs, and self-identification as being homosexual or gay were associated with ever having tested for HIV. A large majority of Internet-using MSM indicated they had been tested for HIV at some point in the past. A smaller proportion-but still a majority-reported they had been tested within the year preceding study or survey participation. MSM who self-identify as heterosexual or bisexual, are younger, or who use drugs (including non-injection drugs) may be less likely to have ever tested for HIV. The overall findings of our systematic review are encouraging; however, a subpopulation of MSM may benefit from targeted outreach. These findings indicate unmet needs for HIV testing among Internet-using MSM and identify subpopulations that might benefit from targeted outreach, such as provision of HIV self-testing kits.

Project SMART: Preliminary Results From a Test of the Efficacy of a Swedish Internet-Based HIV Risk-Reduction Intervention for Men Who Have Sex With Men

In Sweden, 57 % of HIV transmission occurs among MSM, and other sexually transmitted infections are increasing, supporting the need for innovative interventions. The Internet is a potentially useful HIV-prevention platform, but there is a lack of such programs in Sweden. The purpose of this exploratory study was to test the efficacy of the Internet-based SMART intervention to decrease HIV sexual risks in Swedish MSM. The intervention was adapted from the Wyoming Rural AIDS Prevention Project to the Swedish context, which was guided by the Information-Motivation-Behavioral (IMB) skills model and consisted of six sessions. A total of 112 men responded to a pretest questionnaire and were randomly assigned to the SMART intervention or to a waitlist group. Fifty-four men dropped out, leaving a final sample of 58 participants. Twenty-five were assigned to the SMART intervention and 33 to a waitlist group. One month post intervention, the number of casual anal sex partners significantly decreased (t = 2.19, p = .04). Compared with the waitlist group, men in the intervention group increased their HIV knowledge (β = 0.70, p = .01), their belief of condom use as an act of responsibility (β = 1.19, p = .04), their willingness to use a condom with every new partner all the time (β = 1.39, p = .03), and their confidence in using condoms in challenging situations (β = 1.65, p = .02). Condom use was not analyzed due to the small sample size. Despite the small sample, high drop-out, and short follow-up, the study provides support for the efficacy of the Internet interventions, the SMART intervention specifically, for reducing the proportion of casual anal sex partners and improving the three cognitive components of the IMB model for Swedish MSM.

Indicators of HIV-risk resilience among men who have sex with men: a content analysis of online profiles

Background: HIV-risk resilience, or positive adaptation in the face of risk, is increasingly being recognised as an important characteristic among men who have sex with men (MSM). However, resilience in the context of online partner seeking remains underexplored among MSM. Methods: Using content analysis methodology, this study operationalised indicators of HIV-risk resilience in the profiles of 933 MSM using a sexual networking website. HIV-risk resilience included endorsing foreplay only (non-penetrative sex) or a versatile sexual position; being "out" (e.g. disclosed sexual orientation), having a profile photo, seeking friendship, seeking a relationship, serosorting, not endorsing alcohol or drug use, safer sexual adventurism (e.g. role playing, bondage), and safer sex. Results: The majority of men were between 18 and 35 years old (76.0%) and 73.3% were racial/ethnic minorities. The mean number of resilience components endorsed was 5.2 (s.d. = 1.5; range 0-9). Nearly half (48.0%) reported being "out" and 68.7% had a profile photo. The majority of men were seeking relationships (66.5%) and/or friendships (69.7%), were sexually versatile (53.3%), and preferred safer sex only (76.3%). The majority did not endorse drug use (82.0%) and 25.4% did not endorse alcohol use. Nearly one-quarter (21.4%) endorsed sexual adventurism and 2.5% were serosorting by partner's HIV negative status. Conclusion: HIV-risk resilience may be common among MSM using sexual networking websites and may manifest in safer sex intentions. Rather than exclusively focusing on sexual risk reduction, health promotion efforts targeting MSM online should acknowledge, measure, and leverage existent HIV-risk resilience strategies in this group.

Is Location of Sex Associated with Sexual Risk Behaviour in Men Who Have Sex with Men? Systematic Review of Within-Subjects Studies

To understand associations between location of sex and sexual risk, it is most helpful to compare sexual encounters within persons. We systematically reviewed within-subjects comparisons of sexual encounters reported by men who have sex with men (MSM) with respect to location of sex. Within-subjects comparisons of sexual risk and location of sex were eligible if they collected data post-1996 from samples of MSM. We independently screened results and full-text records in duplicate. Of 6,336 deduplicated records, we assessed 138 full-text studies and included six, most of which compared unprotected anal intercourse against other anal intercourse. This small, but high quality, body of evidence suggests that associations between attendance at sex-on-premises venues and person-level sexual risk may be due to overall propensity towards unprotected sex. However, there may be some location factors that promote or are associated with serononconcordant unprotected anal intercourse. Health promoters may wish to focus on person-level characteristics.

Impact of alcohol use on sexual behavior among men who have sex with men and transgender women in Lima, Peru

BACKGROUND

Alcohol use disorders (AUDs) may enhance the likelihood of risky sexual behaviors and the acquisition of sexually transmitted infections (STIs). Associations between AUDs with condomless anal intercourse (CAI) and STI/HIV prevalence were assessed among men who have sex with men (MSM) and transgender women (TW) in Lima, Peru.

METHODS

MSM and TW were eligible to participate based on a set of inclusion criteria which characterized them as high-risk. Participants completed a bio-behavioral survey. An AUDIT score ≥8 determined AUD presence. Recent STI diagnosis included rectal gonorrhea/chlamydia, syphilis, and/or new HIV infection within 6 months. Prevalence ratios (PR) were calculated using Poisson regression.

RESULTS

Among 312 MSM and 89 TW, 45% (181/401) had an AUD. Among those with an AUD, 164 (91%) were hazardous/harmful drinkers, and 17 (9%) had alcohol dependence. Higher CAI was reported by participants with an AUD vs. without, (82% vs. 72% albeit not significant). Reporting anal sex in two or more risky venues was associated with screening AUD positive vs. not (24% vs. 15%, p=0.001). There was no difference in recent STI/HIV prevalence by AUD status (32% overall). In multivariable analysis, screening AUD positive was not associated with CAI or recent STI/HIV infection.

CONCLUSIONS

In our sample AUDs were not associated with CAI or new HIV infection/recent STI. However higher prevalence of CAI, alcohol use at last sex, and anal sex in risky venues among those with AUDs suggests that interventions to reduce the harms of alcohol should be aimed toward specific contexts.
