ObjectivesWhile pre-exposure prophylaxis (PrEP) prevents HIV acquisition among gay, bisexual and other men who have sex with men (GBM), PrEP-using GBM may be more likely to engage in sexual behaviours associated with bacterial STIs. We examined associations between PrEP use, condomless anal sex (CAS), number of anal sex partners, oral sex and bacterial STI diagnoses among GBM living in Canada’s three largest cities.MethodsAmong HIV-negative/unknown-status GBM in the baseline of the Engage cohort study, we fit a structural equation model of the associations between any PrEP use, sexual behaviours and bacterial STI diagnosis. We estimated direct and indirect paths between PrEP use and STI via CAS, number of anal sex partners and oral sex.ResultsThe sample included 2007 HIV-negative/unknown status GBM in Montreal, Toronto and Vancouver. There was a significant direct association between PrEP use and current STI diagnosis (β=0.181; 95% CI: 0.112 to 0.247; p<0.001), CAS (β=0.275; 95% CI: 0.189 to 0.361; p<0.001) and number of anal sex partners (β=0.193; 95% CI: 0.161 to 0.225; p<0.001). In the mediated model, the direct association between PrEP use and STIs was non-significant. However, the indirect paths from PrEP to CAS to STIs (β=0.064; 95% CI: 0.025 to 0.120; p=0.008), and from PrEP to greater number of anal sex partners to CAS to STIs were significant (β=0.059; 95% CI: 0.024 to 0.108; p=0.007).ConclusionsOur study adds to the growing awareness that PrEP use among GBM may be associated with bacterial STIs because PrEP users have more anal sex partners and are more likely to engage in CAS. The results underscore the importance of providing effective STI counselling and regular testing to PrEP users, adapting PrEP care and related STI testing to individual needs, and the need for effective prevention strategies for bacterial STIs.

Objective: Supportive social relationships can have direct positive effects on health and mitigate the negative impact of stressors. This study investigated the main effect of perceived social support on STI/HIV risk and prevention behaviors. The buffering effect of perceived social support on the impact of proximal minority stressors, like internalized homonegativity, was also examined on one risk behavior specifically, condomless anal sex (CAS) without HIV pre-exposure prophylaxis (PrEP) use. Methods: HIV-negative gay, bisexual, and other men who have sex with men (GBM) were recruited using respondent driven sampling from three major Canadian urban centers (n = 1,409). GBM completed measures of perceived social support, proximal minority stress, and engagement in STI/HIV risk and prevention behaviors. Results: Higher perceived social support was positively associated with a several health behaviors, including recent STI and HIV testing, discussing HIV status with prospective partners, the use of behavioral HIV-risk reduction strategies during sexual encounters, and a lower likelihood of engaging in CAS without PrEP. There was evidence of moderation as well. Among GBM with higher perceived social support, internalized homonegativity was no longer associated with increased odds of engaging in CAS without PrEP. Conclusions: The results of the current study advance social support theory to GBM in the context of biomedical prevention, showing both evidence of both direct associations and buffering effects on STI/HIV risk and prevention behaviors. This highlights the importance of promoting social support seeking in interventions aimed at improving GBM health.

Background This study examined the perceived difficulty of getting help with substance use among sexual and gender minorities who have sex with men (SGMSM) who use methamphetamine during the early COVID-19 period. Methods SGMSM, aged 18+, who reported sex with a man and methamphetamine use in the past 6 months were recruited to complete an online survey using online advertisements. Ordinal regression models examined predictors of greater perceived difficulty of getting help. Explanatory variables included participant characteristics (i.e., age, HIV status, ethnicity, sexuality, gender, region, income) and variables assessing patterns of methamphetamine use (i.e., frequency, % time methamphetamine is used alone and during sex; perceived need for help) and patterns of healthcare access (i.e., regular provider, past substance use service utilization). Results Of 376 participants, most were gay-identified (76.6%), white (72.3%), cisgender (93.6%), and had annual incomes of less than $60,000 CAD (68.9%). Greater perceived difficulty of getting help was associated with having lower income, sometimes using methamphetamine prior to or during sex, and greater perceived need for help. Conclusion Based on these results, we urge greater investments in one-stop, low-barrier, culturally-appropriate care for SGMSM who use methamphetamine. This is especially important given that participants who perceive themselves as needing help to reduce or abstain from substance use perceive the greatest difficulty of getting such help.

Among sexual minority men, gay, bisexual, and queer men (GBQM) may experience differences in terms of their sense of belonging to a sexual minority community (community connectedness), outness about their sexual identity, and their experiences of proximal and distal sexuality-based stressors. Although group membership can confer unique benefits to members of marginalized groups, including GBQM, these Psychology of Men & Masculinities

We sought to examine how condom use was differentially reasoned by gay, bisexual and other men who have sex with other men (GBM) in Ontario, Canada. Data were derived from a community-based study of GBM who completed an anonymous online questionnaire in 2014. Participants qualitatively described reasons a condom was used or not at their most recent anal sex event. Qualitative responses were thematically coded non-exclusively and associations with event-level and individual-level factors were determined quantitatively using manual backward stepwise multivariable logistic regression. Among 1,830 participants, 1,460 (79.8%) reported a recent anal sex event, during which 884 (60.6%) used condoms. Reasons for condom use included protection/safety (82.4%), norms (30.5%), and combination prevention (6.2%). Reasons for non-use were intentional (43.1%), trust (27.6%), unintentional (25.7%), and other strategies (19.6%). Event-level substance use was associated with all non-use reasons: e.g., more likely to be unintentional, less likely to be trust. Condom non-use with online-met partners was associated with more intentional and unintentional reasons and less trust reasons. Non-white and bisexual GBM were less likely to explain condom use as a norm. Participant-partner HIV status was an important predictor across most condom use and non-use reasons: e.g., sero-different partnerships were more likely to reason condom use as combination prevention and condom non-use as trust, unknown status partnerships were more likely to reason non-use as unintentional. Condom use among GBM is a multi-faceted practice, especially with increasing antiretroviral-based HIV prevention. Future interventions must adapt to changing GBM (sub-)cultures with targeted, differentiated, culturally-appropriate, and sustained interventions.

Crystal methamphetamine (CM) disproportionately impacts gay, bisexual, and other men who have sex with men (gbMSM). However, not all gbMSM are interested in changing their substance use. The present study aimed to examine whether participant-preferred service characteristics were associated with their readiness to change. We surveyed gbMSM who used CM in the past six months, aged 18 plus years, on dating platforms. Participants rated service-design characteristics from “very unimportant” to “very important”. Multivariable regression tested service preference ratings across levels of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES-8D). Among 291 participants, 38.7% reported their CM use was not problematic, 19.5% were not ready to take any action to reduce or stop using CM, and 41.7% were ready to take action. On average, participants rated inclusive, culturally-appropriate, out-patient counselling-based interventions as most important. Participants with greater readiness-to-change scores rated characteristics higher than gbMSM with lesser readiness. Contingency management and non-abstinence programming were identified as characteristics that might engage those with lesser readiness. Services should account for differences in readiness-to-change. Programs that provide incentives and employ harm reduction principles are needed for individuals who may not be seeking to reduce or change their CM use.
