Abstract
This study aimed to investigate the impact of sexual partners' HIV serostatus awareness on the HIV acquisition among men who have sex with men (MSM) in Guangzhou, China. A nested case-control study was conducted based on a prospective cohort of MSM in Guangzhou. Within the cohort, individuals who underwent HIV seroconversion were identified as the case group, and each case was matched with four controls from the non-seroconverted participants. Information regarding the awareness of sexual partners' HIV serostatus over the preceding 6 months was gathered. Of the 161 participants, 36.0% were aware of the HIV serostatus of all their sexual partners. The practice of engaging in condomless anal sex with partners of unknown HIV serostatus and being aware of the HIV serostatus of only some casual partners were positively correlated with an elevated risk of acquiring HIV. Conversely, being fully aware of the HIV serostatus of all sexual partners, including regular ones, was associated with a diminished risk of HIV incidence. Regular communication with sexual partners regarding HIV testing outcomes, honest disclosure of one's own HIV serostatus, and refusal of sexual contact with partners of unknown HIV serostatus can potentially mitigate the risk of acquiring HIV among MSM.

The relevance of communal altruism for sexual minority men in contemporary contexts. JOURNAL OF COMMUNITY PSYCHOLOGY 2023; 51:1461-1478. [PMID: 35932490 DOI: 10.1002/jcop.22923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 06/17/2022] [Accepted: 07/24/2022] [Indexed: 05/23/2023]
Abstract
There are many reasons why individuals engage in prosocial behavior; communal sexual altruism is based on the notion that some practice safer sex in the interest of promoting the well-being of their community/in-group. Given that definitions of what constitutes "safer sex" have changed with advances in human immunodeficiency virus (HIV) prevention, we investigated the importance of communal sexual altruism (herein "altruism") among urban gay, bisexual, and other sexual minority men (GBM) in the contemporary context. Using a sample of 2449 GBM we examined the association of both safer-sex-related attitudes (e.g., HIV treatment optimism-skepticism) and behaviors (e.g., condomless anal sex [CAS]) with altruism scores. Higher altruism scores were associated with a lower likelihood of CAS and a greater frequency of discussing HIV status with new partners. These findings demonstrate that many GBM are motivated to engage in several kinds of behaviors that improve the well-being of their in-group (i.e., the GBM community).

Abstract
This study identified patterns of sexualized substance use among gay, bisexual, and other men who have sex with men (gbMSM) and examined associated risk factors for sexually transmitted and blood borne infections (STBBI). Data were from a longitudinal cohort recruited using respondent-driven sampling between Feb-2017 and Feb-2019. Participants reported on events with up to five of their most recent sexual partners. Latent class analysis examined patterns of concurrent substance use 2 h prior to or during sex. Multinomial regression identified demographic, partner-level, and event-level factors associated across 11,877 sexual events reported by 757 participants. Most combinations of substance use were rare, but most drugs were frequently combined with other drugs when they were used prior to or during a sexual event. Six latent classes of concurrent event-level substance use were identified. The referent class (58.8% of events) was characterized by limited use of any drugs. The Common Drug Use class (12.1%) was characterized by use of alcohol, cannabis, and poppers and the Licit Drug Use class (21.6%) was characterized by use of alcohol alone. The Party 'N' Play (PnP) class (2.3%) was characterized by use of crystal methamphetamine GHB, Poppers, and Erectile Drugs; The Multi-use (3.5%) class was characterized by the PnP substances plus alcohol and ecstasy; and the Cannabis + class was characterized by use of Cannabis, Erectile Drugs, and Ecstasy. Relative to the referent class, all other classes were associated with events with more behavioural and network risk factors for STBBIs-highlighting the need for harm reduction interventions for gbMSM who use these drugs.

JMIR Public Health Surveill 2023; 9:e43394. [PMID: 36795477 PMCID: PMC9982722 DOI: 10.2196/43394] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 01/06/2023] [Accepted: 01/11/2023] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Mobile voluntary counseling and testing (VCT) for HIV has been carried out to improve the targeting of at-risk populations and HIV case detection for men who have sex with men (MSM). However, the HIV-positive detection rate using this screening strategy has declined in recent years. This may imply unknown changes in risk-taking and protective features jointly influencing the testing results. These changing patterns in this key population remain unexplored. OBJECTIVE The aim of this study was to identify the nuanced group classification of MSM who underwent mobile VCT using latent class analysis (LCA), and to compare the difference in characteristics and testing results between subgroups. METHODS A cross-sectional research design and purposive sampling were applied between May 21, 2019, and December 31, 2019. Participants were recruited by a well-trained research assistant through social networking platforms, including the most popular instant messenger app Line, geosocial network apps dedicated to MSM, and online communities. Mobile VCT was provided to participants at an assigned time and place. Demographic characteristics and risk-taking and protective features of the MSM were collected via online questionnaires. LCA was used to identify discrete subgroups based on four risk-taking indicators-multiple sexual partners (MSP), unprotected anal intercourse (UAI), recreational drug use within the past 3 months, and history of sexually transmitted diseases-and three protective indicators-experience of postexposure prophylaxis, preexposure prophylaxis use, and regular HIV testing. RESULTS Overall, 1018 participants (mean age 30.17, SD 7.29 years) were included. A three-class model provided the best fit. Classes 1, 2, and 3 corresponded to the highest risk (n=175, 17.19%), highest protection (n=121, 11.89%), and low risk and low protection (n=722, 70.92%), respectively. Compared to those of class 3, class 1 participants were more likely to have MSP and UAI within the past 3 months, to be ≥40 years of age (odds ratio [OR] 2.197, 95% CI 1.357-3.558; P=.001), to have HIV-positive results (OR 6.47, 95% CI 2.272-18.482; P<.001), and a CD4 count ≤349/μL (OR 17.50, 95% CI 1.223-250.357; P=.04). Class 2 participants were more likely to adopt biomedical preventions and have marital experience (OR 2.55, 95% CI 1.033-6.277; P=.04). CONCLUSIONS LCA helped derive a classification of risk-taking and protection subgroups among MSM who underwent mobile VCT. These results may inform policies for simplifying the prescreening assessment and more precisely recognizing those who have higher probabilities of risk-taking features but remain undiagnosed targets, including MSM engaging in MSP and UAI within the past 3 months and those ≥40 years old. These results could be applied to tailor HIV prevention and testing programs.

Abstract
This study aimed to identify Top, Bottom, and Versatile sexual role identities and anal sex behavior profiles using latent class analysis in a sample of 942 sexual minority men living in Bogotá. A Versatile-insertive and receptive class (52.2%) was the most prevalent of the four resulting classes, whereas the least common was a class (1.7%) that did not use labels and had a low probability of anal sex. We examined whether identity and relational factors (i.e., sexual orientation, LGBT collective identity, and partner type) were associated with profiles. Gay identity was associated with versatile and receptive classes and bisexual identity was associated with insertive and versatile classes. LGBT collective identity was associated with the class characterized by Bottom identity and receptive positioning. Partner type was not associated with class membership, but versatile behaviors were more common among encounters with a main partner. Models using data at different timescales offered consistent patterns of behavior between the last encounter and the past three months, though the versatile class in the three-month model split into two classes based on frequency of versatile positioning. Findings highlight the relationship between sexual identity and positioning and can inform interventions for sexual health education and identity development.

Latent Class Analysis of Polysubstance Use and Sexual Risk Behaviors among Men Who Have Sex with Men Attending Sexual Health Clinics in Mexico City. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148847.

Abstract
Men who have sex with men (MSM) are more likely to use drugs and other substances compared to their heterosexual peers. No studies have evaluated patterns of substance use among MSM adults in Mexico. We used latent class analysis (LCA) to identify MSM subgroups with specific substance use patterns and their associations with sexual behaviors. Methods: Data from 1850 adult MSM were collected at HIV clinics in Mexico City between September 2018 and December 2019. The structural equation modeling approach was used to estimate a LC model to identify patterns of substance use by self-report of substance use (i.e., cigarette smoking, alcohol, and drugs). To evaluate LC membership, we included HIV status, condomless anal sex (CAS), and serosorting, while controlling for demographic variables. Results: 30.3% were under the age of 22. Alcohol use in last 30 days (76.2%), binge drinking (29.2%), marijuana (29.4%), sex-drugs (23.9%), stimulants (13.7%), and depressants (6.3%). MSM reported engaging in CAS (55.9%) and serosorting (13.5%) behaviors, and 40% reported being HIV positive. LCA indicated three general categories of MSM substance users: Class 1 (49.0%), Class 2 (29.8%), and Class 3 (20.4%). Members of Class 3 were younger: 23–28 age years (aOR = 1.86) and 29–33 age years (aOR = 1.86), more educated: completed graduate studies (aOR = 1.60), had a high probability of polysubstance use and were more likely to engage in CAS and serosorting. Conclusions: Attempts to detect alcohol and problematic use of substances are needed for MSM followed by culturally competent approaches that address alcohol and drug use disorders.

Abstract
BACKGROUND Young Black gay, bisexual, and other men who have sex with men (YBMSM) are disproportionally affected by HIV. Seroadaptive strategies-modification of sexual behavior based on an individual's perceived serostatus, the perceived status of the partner, and/or HIV transmission risk by the type of sex act-are often used to reduce the risk of HIV transmission or acquisition. METHODS We used demographic, behavioral, and clinical data from Ele[MEN]t, a prospective cohort study of YBMSM aged 18-29 years in Atlanta, GA, conducted during 2015-2019. The prevalence of seroadaptive strategies at baseline was reported, and latent class analysis was used to identify the latent classes of strategies for both YBMSM known and not known to be living with HIV. Latent classes were compared by key behavioral and clinical characteristics to validate our findings. RESULTS In a 4-class model, the most common latent class of YBMSM not known to be living with HIV (32.4%) was characterized by all individuals reporting only having sex with men not perceived to be living with HIV. The most common latent class of YBMSM known to be living with HIV (48.2%) was characterized by a combination of serosorting strategies, including using condoms for anal sex with partners not known to be living with HIV and avoiding sex with men not known to be living with HIV. CONCLUSIONS YBMSM use various patterns of strategies to reduce their HIV transmission or acquisition risk. Our study highlights the need for targeted HIV prevention recommendations based on individual behaviors.

Abstract
Men Who Have Sex with Men and Women (MSMW) experience discrimination from same-sex and heterosexual communities partially because of perceptions they feature high-risk sexual behavior, elevated polysubstance use levels, and constitute an HIV bridge population. We used a longitudinal multivariate generalized linear mixed model comparing sexual risk and substance use patterns for Men Who Have Sex with Men Only (MSMO) with MSMW in the same cohort study. Data consisted of 771 men reporting 3,705 sexual partnerships from 2012-2017. For high-risk sexual behavior multivariate results showed non-significant (p>0.05) differences for partner number and commercial sex work, and significantly less (p<0.05) HIV prevalence and condomless anal sex. However, MSMW had significantly higher levels of hallucinogen and prescription opioid use, and substance treatment histories. Only one HIV-positive MSMW had a transmittable viral load, negating the concept of an HIV bridge population. Results indicate the need for additional longitudinal studies comparing MSMO and MSMW.

Abstract
In a body of research typically focused on risk reduction and disease prevention, other factors motivating the sexual behaviours of Latino sexual minority men, such as resource-based power and sexual pleasure, are less well understood. To this end, Latino immigrant sexual minority men living in New York City were surveyed about their sexual behaviours, perceived power differentials, and pleasure from insertive and receptive anal intercourse. Power and pleasure were examined as associations with behavioural profiles identified through latent class analysis, adjusting for age and partner type. Four latent classes of Latino sexual minority men were identified based on behaviours reported during the most recent sexual event: behaviourally insertive (14.2%), behaviourally versatile (25.9%), behaviourally receptive (29.2%), and limited penetrative behaviour (30.7%). Participants who derived pleasure from insertive and receptive anal intercourse had higher odds of belonging in the behaviourally insertive and behaviourally receptive class, respectively. Perceptions of resource-based power were not associated with class membership. Findings highlight the importance of sexual pleasure as a driver of sexual behaviour, irrespective of power dynamics. Sexual health curricula and interventions for sexual minority men should consider sexual pleasure and sex-affirmative frameworks when providing sexuality education and promoting sexual wellbeing.

[PMID: 33984688 DOI: 10.1016/j.epidem.2021.100461] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 03/09/2021] [Accepted: 04/05/2021] [Indexed: 11/30/2022] Open
Abstract
INTRODUCTION In British Columbia (BC), the HIV epidemic continues to disproportionally affect the gay, bisexual and other men who have sex with men (MSM). In this study, we aimed to evaluate how Treatment as Prevention (TasP) and pre-exposure prophylaxis (PrEP), if used in combination, could lead to HIV elimination in BC among MSM. METHODS Considering the heterogeneity in HIV transmission risk, we developed a compartmental model stratified by age and risk-taking behaviour for the HIV epidemic among MSM in BC, informed by clinical, behavioural and epidemiological data. Key outcome measures included the World Health Organization (WHO) threshold for disease elimination as a public health concern and the effective reproduction number (Re). Model interventions focused on the optimization of different TasP and PrEP components. Sensitivity analysis was done to evaluate the impact of sexual mixing patterns, PrEP effectiveness and increasing risk-taking behaviour. RESULTS The incidence rate was estimated to be 1.2 (0.9-1.9) per 1000 susceptible MSM under the Status Quo scenario by the end of 2029. Optimizing all aspects of TasP and the simultaneous provision of PrEP to high-risk MSM resulted in an HIV incidence rate as low as 0.4 (0.3-0.6) per 1000 susceptible MSM, and an Re as low as 0.7 (0.6-0.9), indicating that disease elimination was possible when TasP and PrEP were combined. Provision of PrEP to younger MSM or high-risk and younger MSM resulted in a similar HIV incidence rate, but an Re with credible intervals that crossed one. CONCLUSION Further optimizing all aspects of TasP and prioritizing PrEP to high-risk MSM can achieve the goal of disease elimination in BC. These results should inform public health policy development and intervention programs that address the HIV epidemic in BC and in other similar settings where MSM are disproportionately affected.

Abstract
Social isolation, a risk factor for poor health within the general population, may be exacerbated by unique challenges faced by people living with HIV (PLHIV). This analysis examines the association between social isolation and all-cause mortality among a cohort of PLHIV experiencing multiple social vulnerabilities. The analytical sample included 936 PLHIV ≥ 19 years, living in British Columbia, Canada, and enrolled in the Longitudinal Investigation into Supportive and Ancillary Health Services (LISA) Study (2007–2010). Participants were classified as Socially Connected (SC), Minimally Isolated (MI) or Socially Isolated (SI) via latent class analysis. Cross-sectional survey data was linked to longitudinal clinical data from a provincial HIV treatment database. Mortality was assessed longitudinally up to and including December 31st, 2017. Through multivariable logistic regression, an association between SI and all-cause mortality was found (adjusted OR: 1.48; 95% CI 1.08, 2.01). These findings emphasize the need to mitigate effects of social isolation among PLHIV.

Abstract
Pre-exposure prophylaxis (PrEP) became publicly available in Quebec for gay, bisexual and other men who have sex with men (GBM) in 2013. We used baseline data from Engage, a cohort of GBM recruited by respondent-driven sampling, to examine patterns of combination HIV prevention use among Montreal GBM since PrEP became available. Latent class analysis, stratified by HIV status, was used to categorize GBM by self-reported use of biomedical and behavioural prevention strategies. Correlates of resulting classes were identified using multinomial logistic regression. Among HIV-negative/unknown GBM (n = 968), we identified four classes: low use of prevention (32%), condoms (40%), seroadaptive behaviour (21%), and biomedical (including PrEP; 7%). Those using prevention (condoms, seroadaptive behaviour, and biomedical) had a higher number of anal sex partners and were more likely to report a recent sexually transmitted infection diagnosis. GBM using biomedical prevention also had a higher level of formal education. Among GBM living with HIV (n = 200), we identified three classes: mainly antiretroviral treatment (ART) with viral suppression (53%), ART with viral suppression and condoms (19%), and ART with viral suppression and seroadaptive behaviour (18%). Again, the number of anal sex partners was higher among those using condoms and seroadaptive behaviours. Our findings show antiretroviral-based prevention, either alone or in combination with other strategies, is clearly a component of the HIV prevention landscape for GBM in Montreal. Nevertheless, PrEP uptake remains low, and there is a need to promote its availability more widely.

Abstract
Our study aims to define and identify correlates of social isolation among people living with HIV (PLHIV). The Longitudinal Investigation into Supportive and Ancillary health services (LISA) study provided a cross-sectional analytic sample of 996 PLHIV in British Columbia, Canada (sampled between 2007 and 2010). Individuals marginalized by socio-structural inequities were oversampled; sampling bias was addressed through inverse probability of participation weighting. Through latent class analysis, three groups were identified: Socially Connected (SC) (n = 364, 37%), Minimally Isolated (MI) (n = 540, 54%) and Socially Isolated (SI) (n = 92, 9%). Correlates of the SI and MI classes, determined through multivariable multinomial regression using the SC class as a reference, include: recent violence (aOR 1.61, 95%CI 1.28-2.02 [MI vs. SC]; aOR 2.04, 95%CI 1.41-2.96 [SI vs. SC]) and a mental health diagnosis (aOR 1.50, 95% CI 1.31-1.72 [MI vs. SC]; aOR 1.43, 95%CI 1.11-1.83 [SI vs. SC]). Women (aOR 0.47; 95%CI 0.32-0.68 [SI vs. SC]), individuals of Indigenous ancestry (aOR 0.59; 95%CI 0.40-0.87 [SI vs. SC]) and people identifying as gay or lesbian (aOR 0.37; 95%CI 0.26-0.52 [SI vs. SC]) were less likely to experience isolation. These findings highlight the importance of supporting communities fostering connectedness and identifies populations susceptible to isolation.

Abstract
McKirnan's Cognitive Escape Theory (1996) is often characterized by the hypothesis that drugs are used during sex by gay, bisexual, and other men who have sex with men (gbMSM) to relieve internal cognitive conflict over safe-sex norms and sexual desire. We examined how McKirnan's Cognitive Escape Scale (CES) is related to other widely used constructs relevant to sexualized substance use with hopes of better situating the theory within the evolving landscape of HIV-prevention. Associations between CES and trait anxiety, depression, treatment optimism, sexual altruism, sexual sensation seeking, and self-perceived risk for HIV transmission/acquisition were tested. Mediation analyses tested whether associated psychological measures mediated the effect of CES on the proportion of events in which participants reported co-occurrent substance use and condomless anal sex. Results indicated that CES is associated with higher sexual sensation seeking, treatment optimism, trait anxiety, and perceived likelihood of HIV transmission/acquisition. Mediation analyses suggest that CES is related to but operates independently of treatment optimism, sensation seeking, and trait anxiety. Nevertheless, the intersection of HIV-related worries and substance use expectancies are clearly more nuanced than is widely reported is discussions on cognitive escape.

Abstract
Gay and bisexual Men Who Have Sex with Men (GBM) are sexually unique in that they can practice penile-anal sex versatility, i.e. engage in insertive and receptive anal sex. Individual-level versatility is extensively researched both as a sexual behavior linked to HIV/STI transmission, and as a GBM identity that can change over time. However, there is a dearth of research on event-level versatility (ELV), defined as taking the receptive and insertive role in the same sexual encounter. We analyzed event-level data from 644 GBM in the Momentum Health Study from February 2012-February 2017 to identify factors associated with ELV prevalence, the relationship between ELV and anal sex role preference, and sero-adaptive and sexualized drug use strategies. Univariate analysis revealed ELV prevalence rates between 15% and 20%. A multivariate generalized linear mixed model indicated ELV significantly (p < .05) associated with versatile role preference and condomless sex. However, the majority of ELV came from GBM reporting insertive or receptive role preferences, and there was significantly higher condom use among sero-discordant partners, indicating sero-adaptation. Multivariate log-linear modeling identified multiple polysubstance combinations significantly associated with ELV. Results provide insights into GBM sexual behavior and constitute empirical data useful for future HIV/STI transmission pattern modeling.

Abstract
A scoping literature review to identify the multilevel HIV serosorting related elements was developed. Articles from EBSCO, PubMed, PsyNET and Science Direct with serosort* or serosorting at the tittle or abstract, written in English or Spanish were included. No restriction in type of population or design were applied. 239 records were retrieved after duplicates removed, but 181 references were extracted for full-text review. Individual level: HIV knowledge, serostatus, risk perceptions, abilities to disclose and for condom use negotiation, motivations, use of drugs, stigma, attitudes toward condom use, and perceptions/beliefs about the HIV and related treatments, HIV infection rates/testing and behavioral factors. Interpersonal level: social networks, abilities (sexual behavior negotiation, and communication). Community level: stigma, social norms, access to HIV related services. Structural level: political context, HIV related funding and public policies. HIV Serosorting is not solely an interpersonal behavior it involves multilevel elements that must be acknowledged by professionals and stakeholders.

Abstract
Sexual scientists must choose from among myriad methodological and analytical approaches when investigating their research questions. How can scholars learn whether sexualities are discrete or continuous? How is sexuality constructed? And to what extent are sexuality-related groups similar to or different from one another? Though commonplace, quantitative attempts at addressing these research questions require users to possess an increasingly deep repertoire of statistical knowledge and programming skills. Recently developed open-source software offers powerful yet accessible capacity to researchers wishing to perform strong quantitative tests. Taking advantage of these new statistical opportunities will require sexual scientists to become familiar with new analyses, including taxometric analysis, tests of measurement variability and differential item functioning, and equivalence testing. In the current article, I discuss each of these analyses, providing conceptual and historical overviews. I also address common misunderstandings for each analysis that may discourage researchers from implementing them. Finally, I describe current best practices when using each analysis, providing reproducible coding examples and interpretations along the way, in an attempt to reduce barriers to the uptake of these analyses. By aspiring to explore these new statistical frontiers in sexual science, sexuality researchers will be better positioned to test their substantive theories of interest.

Abstract
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").

Abstract
This study examined patterns of connectedness among 774 sexually-active gay, bisexual, and other men who have sex with men (GBM), aged ≥ 16 years, recruited using respondent-driven sampling in Metro Vancouver. Latent class analysis examined patterns of connectedness including: attendance at gay venues/events (i.e., bars/clubs, community groups, pride parades), social time spent with GBM, use of online social and sex seeking apps/websites, and consumption of gay media. Multinomial regression identified correlates of class membership. A three-class LCA solution was specified: Class 1 "Socialites" (38.8%) were highly connected across all indicators. Class 2 "Traditionalists" (25.7%) were moderately connected, with little app/website-use. Class 3 "Techies" (35.4%) had high online connectedness and relatively lower in-person connectedness. In multivariable modelling, Socialites had higher collectivism than Traditionalists, who had higher collectivism than Techies. Socialites also had higher annual incomes than other classes. Techies were more likely than Traditionalists to report recent serodiscordant or unknown condomless anal sex and HIV risk management practices (e.g., ask their partner's HIV status, get tested for HIV). Traditionalists on the other hand were less likely to practice HIV risk management and had lower HIV/AIDS stigma scores than Socialites. Further, Traditionalists were older, more likely to be partnered, and reported fewer male sex partners than men in other groups. These findings highlight how patterns of connectedness relate to GBM's risk management.

Abstract
BACKGROUND We evaluated attitudes toward treatment as prevention (TasP) among gay, bisexual, and other men who have sex with men (GBM) in Vancouver, Canada. METHODS Sexually active GBM, aged ≥16 years, were recruited between 2012 and 2015 using respondent-driven sampling. At each 6-month follow-up, participants completed a computer-administered questionnaire and nursing visit. Repeated-measures latent class analysis, grouped by self-reported serostatus, identified patterns of TasP endorsement by considering TasP-related awareness, attitudes, and behavior. Binary logistic regression identified covariates of class membership. Bivariate interactions with visit number identified factors associated with longitudinal changes in class membership. RESULTS A total of 774 men provided 2590 observations. Of these, 698 enrolled in the cohort, 575 had at least 1 follow-up visit. Among these, the median follow-up time was 1.98 years (Q1-Q2: 1.49-2.49 years). Repeated-measures latent class analysis identified 3 classes: "unaware" (64.2% HIV negative/unknown vs. 29.2% of HIV positive), "skeptical" (29.7% vs. 23.1%), and "believing" (6.1% vs. 47.7%). Membership in classes representing higher TasP endorsement was associated with greater odds of condomless anal sex and having more sexual partners. Age, sexual orientation, ethnicity, substance use, and social time spent with other GBM were also associated with class membership. Longitudinally, class membership was stable among HIV-positive men but shifted toward greater TasP endorsement among HIV-negative/unknown men. For HIV-negative/unknown men, increasing endorsement was positively associated with greater education, being employed, being in a relationship, and substance use and inversely associated with recent serodiscordant condomless anal sex or sexually transmitted infection diagnosis. CONCLUSIONS Over time, disparities in TasP diffusion by HIV status have lessened, although continue to persist across other key social strata.
