RESUMO
OBJECTIVE: Sexual minority men (SMM) living with HIV report significantly greater methamphetamine use compared with heterosexual and HIV-negative peers. Greater use may be related to stressors (e.g., HIV-related stigma) faced by SMM living with HIV and subsequent psychological and behavioral sequelae. We tested an integrated theoretical model comprised of pathways between stigma, discrimination, childhood sexual abuse, psychological distress, sexual compulsivity, and cognitive escape in predicting methamphetamine use among SMM living with HIV. METHODS: Among 423 SMM living with HIV, we tested a structural equation model examining factors hypothesized to be directly and indirectly associated with methamphetamine use. Analyses were adjusted for demographic covariates and sampling bias. RESULTS: The model showed good fit (CFI = 0.96, RMSEA = 0.01). Heterosexist discrimination was associated with psychological distress (ß = 0.39, p < 0.001) and psychological distress was associated with sexual compulsivity (ß = 0.33, p < 0.001). Sexual compulsivity was associated with cognitive escape (ß = 0.31, p < 0.001), which was associated with methamphetamine use (ß = 0.51, p < 0.001). Psychological distress was associated with methamphetamine use via serial indirect effects of sexual compulsivity and cognitive escape (ß = 0.05, p < 0.05). CONCLUSIONS: Heterosexist discrimination contributed to psychological distress among SMM living with HIV. Psychological distress is linked to methamphetamine use via sexual compulsivity and cognitive avoidance. Interventions seeking to reduce the likelihood that SMM living with HIV use methamphetamine should include coping strategies specific to heterosexism and related psychological distress.

BACKGROUNDS: Positive attitudes toward human immunodeficiency virus (HIV) treatment, such as reduced concern about HIV transmissibility, are associated with sexual behaviors that may increase the risk of bacterial sexually transmitted infections (STIs) among gay, bisexual, and other men who have sex with men (GBM). We examined associations between HIV treatment attitudes and bacterial STI diagnoses among GBM in Canada's three largest cities. METHODS: We fit a structural equation model between HIV treatment attitudes and bacterial STI diagnoses via sexual behaviors in the Engage study's baseline data. We estimated direct and indirect paths between scores on HIV treatment attitudes and STIs via number of male anal sex partners, condomless anal sex, and oral sex. We conducted sub-analyses with participants stratified by HIV serostatus. RESULTS: Among 2449 GBM recruited in 2017 to 2019, there was a direct association between HIV treatment attitudes and current STI diagnoses (ß = 0.13; 95% CI, 0.07-0.19; P < 0.001). The mediated model revealed a positive total indirect effect through 2 pathways: (1) engaging in condomless anal sex and (2) number of male anal sex partners and condomless anal sex. These 2 indirect pathways remained in the stratified mediation models for both HIV negative GBM and for GBM living with HIV. CONCLUSIONS: The association between HIV treatment attitudes and diagnosed STIs is mediated through a higher number of male anal sex partners and condomless anal sex. The results highlight the importance of providers educating patients when providing effective STI counseling, testing, and prevention for GBM about how accurate HIV treatment attitudes may inadvertently be associated with the bacterial STI epidemic.

BACKGROUND: We explored attitudes of gay, bisexual, and other men who have sex with men (GBM) toward their amphetamine-use and associations with reduced use over time. METHODS: We recruited sexually-active GBM aged 16+ years in Montreal, Toronto, and Vancouver, Canada, from 02-2017 to 08-2019, with follow-up visits every 6-12 months until November 2020. Among participants who reported past-six-month (P6M) amphetamine-use at enrollment, we used logistic regression to identify demographic, psychological, social, mental health, other substance-use, and behavioral factors associated with reporting needing help reducing their substance-use. We used mixed-effects logistic regression to model reduced P6M amphetamine-use with perceived problematic-use as our primary explanatory variable. RESULTS: We enrolled 2,449 GBM across sites. 15.5-24.7% reported P6M amphetamine-use at enrollment and 82.6 - 85.7% reported needing no help or only a little help in reducing their substance use. Reporting needing a lot/of help or completely needing help in reducing substance-use was associated with group sex participation (AOR = 2.35, 95%CI:1.25-4.44), greater anxiety symptomatology (AOR = 2.11, 95%CI:1.16-3.83), greater financial strain (AOR = 1.35, 95%CI:1.21-1.50), and greater Escape Motive scores (AOR = 1.07, 95%CI:1.03-1.10). Reductions in P6M amphetamine-use were less likely among GBM who perceived their amphetamine-use as problematic (AOR = 0.17 95% CI 0.10 - 0.29). CONCLUSIONS: Most amphetamine-using GBM did not feel they needed help reducing their substance use, and many reported reduced amphetamine-use at subsequent visits. Those who perceived their use as problematic were less likely to reduce their use. Further interventions to assist GBM in reducing their use are needed to assist those who perceive their use as problematic.

BACKGROUND: The secondary impacts of the COVID-19 pandemic may disproportionately affect gay, bisexual, and other men who have sex with men (GBM), particularly related to HIV prevention and treatment outcomes. We applied syndemic theory to examine PrEP disruptions during the during the height of the COVID-19 pandemic in Vancouver, Canada. METHODS: Sexually-active GBM, aged 16 + years, were enrolled through respondent-driven sampling (RDS) from February 2017 to August 2019. Participants completed a Computer-Assisted Self-Interview every six months and data were linked to the BC PrEP Program (program responsible for publicly funded PrEP in the province) to directly measure PrEP disruptions. The analysis period for this study was from March 2018-April 2021. We used univariable generalized linear mixed models to examine (1) six-month trends for syndemic conditions: the prevalence of moderate/severe depressive or anxiety symptoms, polysubstance use, harmful alcohol consumption, intimate partner violence, and (2) six-month trends for PrEP interruptions among HIV-negative/unknown GBM. We also applied 3-level mixed-effects logistic regression with RDS clustering to examine whether syndemic factors were associated with PrEP interruptions. RESULTS: Our study included 766 participants, with 593 participants who had at least one follow-up visit. The proportion of respondents with abnormal depressive symptoms increased over the study period (OR = 1.35; 95%CI = 1.17, 1.56), but we found decreased prevalence for polysubstance use (OR = 0.89; 95%CI = 0.82, 0.97) and binge drinking (OR = 0.74; 95%CI = 0.67, 0.81). We also found an increase in PrEP interruptions (OR = 2.33; 95%CI = 1.85, 2.94). GBM with moderate/severe depressive symptoms had higher odds (aOR = 4.80; 95%CI = 1.43, 16.16) of PrEP interruptions, while GBM with experiences of IPV had lower odds (aOR = 0.38; 95%CI = 0.15, 0.95) of PrEP interruptions. GBM who met clinical eligibility for PrEP had lower odds of experiencing PrEP interruptions (aOR = 0.25; 95%CI = 0.11, 0.60). CONCLUSION: There were increasing PrEP interruptions since March 2020. However, those most at risk for HIV were less likely to have interruptions. Additional mental health services and targeted follow-up for PrEP continuation may help to mitigate the impacts of the COVID-19 pandemic on GBM.

Purpose: Bidirectional intimate partner violence (IPV), the reporting of both IPV victimization and perpetration, is likely the most common form of violence among gay, bisexual, and other sexual minority men (GBM) and is thought to be part of a larger syndemic of stressors. This purpose of this study was to examine associations between syndemic factors and lifetime bidirectional IPV among GBM in three Canadian cities to inform future interventions. Methods: Data from GBM (N = 2449) were used to fit three logistic regression models with lifetime bidirectional IPV as the outcome and four syndemic factors (i.e., depressive symptomatology, childhood sexual abuse [CSA], illegal drug use, and alcohol misuse) as independent variables. Model 1 examined syndemic factors individually. Model 2 employed a summative scale of syndemic exposure. Model 3 used marginal analysis to examine the relative excess risk of each potential iteration of the syndemic. Results: Thirty-one percent (N = 762) of respondents reported lifetime bidirectional IPV. Each of the syndemic factors were significantly associated with greater odds of reporting bidirectional IPV (Model 1). Model 2 exhibited a dose-response relationship between the number of syndemic factors reported and bidirectional IPV. Model 3 suggested that the specific combination of depressive symptomatology, CSA, and alcohol misuse resulted in the highest risk of lifetime bidirectional IPV. Conclusion: Bidirectional IPV was common in this sample and was associated with a complex interplay of stressors. However, there may be opportunities to target interventions to the specific syndemic issues in an effort to prevent and mitigate this form of IPV in GBM.

OBJECTIVE: Epidemics impact individuals unevenly across race, gender, and sexuality. In addition to being more vulnerable to COVID-19 infection, evidence suggests racialized gender and sexual minorities experienced disproportionate levels of discrimination and stigma during the COVID-19 epidemic. Drawing on Critical Race Theory (CRT), we examined the experiences of gay, bisexual, queer, and other men who have sex with men (GBQM) of colour facing discrimination during COVID-19. DESIGN: Engage-COVID-19 is a mixed methods study examining the impact of COVID-19 on GBQM living in Vancouver, Toronto, and Montréal, Canada. We conducted two rounds of qualitative interviews (November 2020 to February 2021, and June to October 2021) with 93 GBQM to explore the evolving impact of COVID-19 on their lives. Transcripts were coded using inductive thematic analysis. Data analysis was conducted using Nvivo software. RESULTS: Fifty-nine participants identified as Black, Indigenous, and/or a Person of Colour (BIPOC). These GBQM of colour described multiple experiences of discrimination during COVID-19. Although participants did not report experiences of discrimination based on their sexual identity during COVID-19, we found that experiences of racism affected how they were treated within their sexual networks. Experiences of racism were most often reported by East Asian and Black GBQM. These participants faced racism in public and online spaces, primarily in the form of verbal harassment. Several participants were also harassed because they wore face masks. Verbal abuse against GBQM of colour was largely prompted by racist discourses related to COVID-19. CONCLUSION: Racism remains a pernicious threat to the well-being of GBQM of colour. CRT highlights the importance of assessing how sexualized and gendered discourses about race shape the experiences of GBQM of colour navigating multiple epidemics like COVID-19 and HIV. These pervasive discourses unevenly affect racial and sexual minorities across multiple epidemics, and negatively impact health outcomes for these populations.

BACKGROUND: The Engage Study is a longitudinal biobehavioral cohort study of gay, bisexual and other men who have sex with men (GBM) in Toronto, Montreal, and Vancouver. Baseline data (2,449 participants) were collected from February 2017 - August 2019 using respondent-driven sampling (RDS). Recruitment in Montreal required fewer seeds, had a much shorter recruitment period, and recruited the largest sample. METHODS: To better understand why RDS recruitment was more successful in Montreal compared to other sites, we conducted an analysis to examine RDS recruitment characteristics for GBM in each of the three study sites, explore demographic characteristics and measures of homophily, that is, the tendency of individuals to recruit other study participants who are like themselves, and compared motivations for study participation. RESULTS: Montreal had the greatest proportion of participants over the age of 45 (29.1% in Montreal, 24.6% in Vancouver, and 21.0% in Toronto) and the highest homophily for this age group, but homophily was high across the three cities. Montreal also reported the lowest percentage of participants with an annual income greater or equal to $60,000 (7.9% in Montreal, 13.1% in Vancouver and 10.6% in Toronto), but homophily was similar across all three cities. The majority of participants indicated interest in sexual health and HIV as the main reason for participating (36.1% in Montreal, 34.7% in Vancouver, and 29.8% in Toronto). Financial interest as the main reason for participation was low (12.7% in Montreal, 10.6% in Vancouver, and 5.7% in Toronto). CONCLUSION: Taken together, although we found some differences in study demographic characteristics and homophily scores, we were unable to fully explain the different recruitment success based on the data available. Our study underlines the fact that success of RDS implementation may vary by unknown factors, and that researchers should be proactive and flexible to account for variability.

This study evaluated the association between resilience and PrEP use among a population-based sample of Canadian gay, bisexual, and other men who have sex with men (GBM). Sexually active GBM aged ≥ 16 years old were recruited via respondent-driven sampling (RDS) in Toronto, Montreal, and Vancouver from 02/2017 to 07/2019. We conducted a pooled cross-sectional analysis of HIV-negative/unknown GBM who met clinical eligibility for PrEP. We performed multivariable RDS-II-weighted logistic regression to assess the association between scores on the Connor-Davidson Resilience-2 Scale and PrEP. Mediation analyses with weighted logistic and linear regression were used to assess whether the relationship between minority stressors and PrEP use was mediated by resilience. Of 1167 PrEP-eligible GBM, 317 (27%) indicated they took PrEP in the past six months. Our multivariable model found higher resilience scores were associated with greater odds of PrEP use in the past six months (aOR = 1.13, 95%CI = 1.00, 1.28). We found that resilience reduced the effect of the association between heterosexist discrimination and PrEP use. Resilience also mediated the relationship between internalized homonegativity and PrEP use and mediated the effect of the association between LGBI acceptance concern and PrEP use. Overall, PrEP-eligible GBM with higher resilience scores had a greater odds of PrEP use in the past six months. We also found mixed results for the mediating role of resilience between minority stress and PrEP use. These findings underline the continued importance of strength-based factors in HIV prevention.

BACKGROUND: Depression and anxiety are commonly experienced among gay, bisexual and other men-who-have-sex-with-men (gbMSM). We explored factors associated with improvements in mental health symptoms among gbMSM with abnormal depression and anxiety scores over a period of four years, in Vancouver, Canada. METHODS: Sexually active gbMSM ≥16 years of age were recruited using respondent-driven sampling from February 2012 to February 2015. Participants completed a computer-assisted questionnaire which included the Hospital Anxiety and Depression Scale (HADS), and psychometric scales to measure loneliness, self-esteem and social connectedness, every 6 months until July 2019. Generalized linear mixed models were used to assess factors associated with normal/borderline HADS scores (<11) following a previous abnormal score (≥11) for each of anxiety and depression subscales. RESULTS: We recruited 694 participants, of whom 580 had at least one follow-up visit. Across all visits, 43.6 % of participants ever had abnormal anxiety scores and 16.2 % ever had abnormal depression scores. Among those with abnormal anxiety scores, 34.9 % of follow-up visits demonstrated reductions in anxiety scores. Among those with abnormal depression scores 51.0 % of follow-up visits demonstrated reductions in depression scores. Reductions in anxiety scores were associated with increased self-esteem, decreased loneliness and the number of gbMSM seen/spoken to in the previous month. Reductions in depression scores were associated with increased self-esteem, decreased loneliness and having a regular partner. CONCLUSION: Improvements in mental health symptoms were frequently observed. Social connectedness was related with improved anxiety and depression symptoms. Interventions to improve social connectedness may help to improve mental health for gbMSM.

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).

OBJECTIVES: Syphilis rates have increased in BC and disproportionately affect gay, bisexual, and other men who have sex with men (gbMSM). A social marketing campaign (Syphistory) ran from January to September 2017 with the primary goal of increasing syphilis knowledge and a secondary goal of increasing syphilis screening among gbMSM in BC. METHODS: We used pre- and post-campaign surveys to assess changes in syphilis knowledge from a convenience sample of clients attending STI clinics using one-sided t-tests. We used online Piwik metrics to examine the campaign reach, and provincial testing data to examine trends in syphilis screening. We used data from the Engage Study to examine factors associated with campaign awareness and associations with syphilis testing. RESULTS: Of the 2155 visitors to the Syphistory website with known geography, 79.4% were from BC. Moreover, STI clinic participants who saw the campaign demonstrated a greater knowledge of syphilis (9.7/12, 80.8%) than those who did not see the campaign (mean 8.9/12, 74%) (p < 0.001). Provincial syphilis testing rates were 8764 and 9749 in the 12 months before and after the campaign; however, we did not find an overall trend in testing before versus after the campaign (p = 0.147). Among Engage participants, 12.7% reported seeing the campaign and we found an association between campaign exposure and recent syphilis testing (aOR = 2.73; 95% CI = 1.51, 4.93). CONCLUSION: gbMSM who saw the campaign were more likely to report being tested for syphilis in the previous 6 months. STI clinic attendees who reported seeing the campaign also had higher syphilis knowledge compared to those who did not.
RéSUMé: OBJECTIFS: Les taux de syphilis ont augmenté en Colombie-Britannique et affectent de manière disproportionnée les hommes gais, bisexuels et autres hommes ayant des relations sexuelles avec des hommes (gbHARSAH). Une campagne de marketing social (Syphistory) a été mené de janvier à septembre 2017 avec pour objectif principal d'informer sur la syphilis et pour objectif secondaire d'augmenter le dépistage de la syphilis chez les gbHARSAH en Colombie-Britannique. MéTHODES: Nous avons réalisé deux sondages, l'un avant et l'autre après la campagne, sur un échantillon de convenance constitué de patients fréquentant des cliniques ITS, pour évaluer les changements dans les connaissances sur la syphilis à l'aide de tests t unilatéraux. Nous avons utilisé les mesures Piwik en ligne pour examiner la portée de la campagne et les données provinciales sur les tests pour examiner les tendances quant au dépistage de la syphilis. Nous avons utilisé les données de l'étude Engage à Vancouver, pour identifier les facteurs associés à la sensibilisation lors de la campagne et les associations avec le dépistage de la syphilis. RéSULTATS: Sur les 2 155 visiteurs du site Web Syphistory dont la position géographique était connue, 79,4 % provenaient de la Colombie-Britannique. De plus, les participants aux cliniques ITS ayant vu la campagne ont démontré une meilleure connaissance de la syphilis (9,7/12, 80,8 %) par rapport à ceux n'ayant pas vu la campagne (moyenne 8,9/12, 74 %) (p<0,001). Les taux provinciaux de dépistage de la syphilis étaient de 8 764 et 9 749 au cours des 12 mois précédant et suivant la campagne; cependant, nous n'avons pas trouvé de tendance globale à la hausse des dépistages suite à la campagne (p=0,147). Parmi les participants Engage, 12,7 % ont déclaré avoir vu la campagne en ligne et nous avons trouvé une association entre l'exposition à la campagne et le dépistage récent de la syphilis (RCa=2,73; IC à 95 %=1,51, 4,93). CONCLUSION: Les gbHARSAH qui ont vu la campagne étaient plus susceptibles de déclarer avoir été testés pour la syphilis au cours des six derniers mois. Les participants aux cliniques ITS qui ont déclaré avoir vu la campagne avaient également une meilleure connaissance de la syphilis que ceux qui ne l'ont pas vue.

In efforts to prevent the spread of COVID-19, jurisdictions across the globe, including Canada, enacted containment measures that affected intimacy and sexual relations. This article examines how public health measures during COVID-19 impacted the sexual practices of sexual minority men- gay, bisexual, queer and other men who have sex with men-and how they adopted and modified guidelines to prevent the transmission of COVID-19, HIV and other sexually transmitted infections (STIs). We conducted 93 semi-structured interviews with men (n = 93) in Montreal, Toronto and Vancouver, Canada, between November 2020 to February 2021 (n = 42) and June to October 2021 (n = 51). Across jurisdictions, participants reported changes to sexual practices in response to public health measures and shifting pandemic contexts. Many men indicated that they applied their HIV/STI risk mitigation experiences and adapted COVID-19 prevention strategies to continue engaging in casual sexual behaviours and ensure sexual safety. 'Social bubbles' were changed to 'sex bubbles'. Masks were turned into 'safer' sex tools. 'Outdoor gathering' and 'physical distancing' were transformed into 'outdoor sex' and 'voyeuristic masturbation'. These strategies are examined in connection to the notion of 'reflexive mediation' to illustrate how sexual minority men are simultaneously self-responsibilising and resistant, self-monitoring and creative.

HIV treatment interruptions are a major public health concern that demonstrate a lack of engagement in care and is detrimental to the health of people living with HIV. Community connectedness have demonstrated a protective effect for psychosocial health but are not well understood for HIV treatment outcomes. We explored associations between community connectedness and treatment interruptions among gay, bisexual and other men who have sex with men (gbMSM) living with HIV in Vancouver, British Columbia. We analyzed survey data from the Momentum Health Study and identified treatment interruptions through data linkages with the provincial HIV Drug Treatment Program as episodes lasting more than 60 days beyond an expected antiretroviral therapy refill date from February 2012 to July 2019. We built a mixed-effects logistic regression model, adjusting for confounders. Of 213 gbMSM living with HIV, 54 experienced treatment interruption (25.4%) over a median five-year follow-up. Multivariable results found the number gbMSM who spoken to in the past month (aOR = 0.995; 95% CI = 0.991, 1.000 (per 100-unit increase)) and attending a gay community meeting more than once per month (aOR = 0.32; 95% CI = 0.11, 0.89) were associated with lower odds of treatment interruptions. These results highlight the importance of social connections in facilitating effective HIV care.

OBJECTIVE: While crystal methamphetamine use by gay, bisexual, and other men who have sex with men (GBM) is associated with increased risk for sexually transmitted infection (STI) transmission, less is understood about the causal pathways between crystal methamphetamine use and STIs. We examined whether the association between greater crystal methamphetamine risk and prevalent bacterial STI diagnosis among GBM was mediated by two types of attitudinal variables: attitudes toward condoms, and sexual escape motives, defined as the use of substances to escape self-awareness during sex, and by sexual behaviors. METHODS: We used computer-assisted self-interview questionnaires from 2449 sexually active GBM (18% living with HIV; median age = 33, interquartile range, 27-45) recruited via respondent-driven sampling in Vancouver, Toronto, and Montreal, Canada. Using the baseline data from the Engage cohort study, we fit a series of structural mediation models of the associations between greater crystal methamphetamine risk and bacterial STI (syphilis, gonorrhea, and chlamydia) diagnosis. We estimated indirect paths from greater crystal methamphetamine risk, attitudes toward condoms, sexual escape motives, and sexual risk behaviors, adjusting for self-reported demographic variables. RESULTS: In the mediated model, the direct association between greater crystal methamphetamine risk and bacterial STI diagnosis was non-significant; however, five indirect paths were significant. Greater crystal methamphetamine risk was associated with bacterial STIs via condom use attitudes and escape motives, which in turn were associated with number of male anal sex partners, condomless anal sex, and oral sex. DISCUSSION: Public health and counselling interventions for GBM who use crystal methamphetamine and who are at higher risk for STIs should target evidence-based causal paths that consider sexual attitudes and sexual practices.

INTRODUCTION: In 2010, British Columbia (BC) implemented HIV Treatment as Prevention (TasP) as policy. We examined trends in virologic suppression and determinants of significant viremia among a prospective biobehavioural cohort of men who have sex with men (gbMSM) in Vancouver from 2012-2017. METHODS: Respondent-driven sampling was used to recruit sexually active gbMSM (≥16 years) who completed biannual study visits with a computer-assisted self-interview and clinical CD4 and viral load (VL) testing. We linked participant data with the BC HIV Drug Treatment Program to obtain antiretroviral dispensing and VL data. We conducted a trend analysis of VL suppression using univariable generalized estimating equation (GEE) multi-level modelling and multivariable GEE to identify factors associated with episodes of VL ≥200 copies/mL. RESULTS: Of 774 participants, 223 were living with HIV at baseline and 16 were diagnosed during follow-up (n = 239). We observed a significant trend towards reduced levels of unsuppressed VL (>200 copies/mL) from 22% (07/2012-12/2012) to 12% (07/2016-12/2016) (OR:0.87; 95%CI:0.83-0.91 for each 6-month period). Among those with at least one follow-up visit, (n = 178, median follow-up = 3.2 years, median age = 46.9 years), younger age (aOR:0.97; 95%CI:0.94-0.99, per year), ecstasy use (aOR:1.69; 95%CI:1.13-2.53), crystal methamphetamine use (aOR:1.71; 95%CI:1.18-2.48), seeking sex via websites (aOR:1.46; 95%CI:1.01-2.12), and lower HIV treatment optimism (aOR:0.94; 95%CI:0.90-0.97) were associated with episodes of elevated viremia. CONCLUSIONS: During a period when TasP policy was actively promoted, we observed a significant trend towards reduced levels of unsuppressed VL. Continued efforts should promote HIV treatment optimism and engagement, especially among younger gbMSM and those who use ecstasy and crystal methamphetamine.

INTRODUCTION: Accessibility of pre-exposure prophylaxis (PrEP) in Canada remains complex as publicly funded coverage and delivery differs by province. In January 2018, PrEP became publicly funded and free of charge in British Columbia (BC), whereas PrEP coverage in Ontario and Montreal is more limited and may require out-of-pocket costs. We examined differences over time in PrEP uptake and assessed factors associated with PrEP awareness and use. METHODS: Gay, bisexual and other men who have sex with men (GBM) were recruited through respondent-driven sampling (RDS) in Toronto, Vancouver and Montreal, Canada, in a prospective biobehavioural cohort study. We applied generalized estimating equations with hierarchical data (RDS chain, participant, visit) to examine temporal trends of PrEP use and correlates of PrEP awareness and use from 2017 to 2020 among self-reported HIV-negative/unknown GBM. RESULTS: Of 2008 self-identified HIV-negative/unknown GBM at baseline, 5093 study visits were completed from February 2017 to March 2020. At baseline, overall PrEP awareness was 88% and overall PrEP use was 22.5%. During our study period, we found PrEP use increased in all cities (all p<0.001): Montreal 14.2% during the first time period to 39.3% during the last time period (p<0.001), Toronto 21.4-31.4% (p<0.001) and Vancouver 21.7-59.5% (p<0.001). Across the study period, more Vancouver GBM used PrEP than Montreal GBM (aOR = 2.05, 95% CI = 1.60-2.63), with no significant difference between Toronto and Montreal GBM (aOR = 0.90, 95% CI = 0.68-1.18). CONCLUSIONS: Full free-of-charge public funding for PrEP in BC likely contributed to differences in PrEP awareness and use. Increasing public funding for PrEP will improve accessibility and uptake among GBM most at risk of HIV.

BACKGROUND: Gay, bisexual, and other men who have sex with men (gbMSM) remain disproportionately affected by human immunodeficiency virus (HIV). Interaction between psychosocial factors likely plays a role in HIV acquisition risk. We aimed to analyze the association of loneliness and self-rated attractiveness with HIV acquisition risk, and determine whether these associations were mediated by gay telephone chatlines or online dating platforms. METHODS: This cross-sectional study included HIV-negative gbMSM 16 years or older enrolled into the Momentum Health Study from February 2012 to February 2015. Loneliness, self-rated attractiveness (exposures) and use of gay chatlines or online dating platforms (mediators) were assessed through self-interviews. Human immunodeficiency virus acquisition risk (outcome) was assessed by the HIV Incidence Risk Index. Weighted logistic regression modeled the association and moderation effect between exposures and outcome. Mediation models estimated 3-way direct effect among exposures, mediators, and outcome. RESULTS: Of 542 gbMSM, those who were lonely (adjusted odds ratio [aOR], 1.54; 95% confidence intervals [CI], 1.04-2.28) and attractive (aOR, 1.69; 95% CI, 1.04-2.76) had increased odds for HIV acquisition risk. Our moderation analysis demonstrated a heightened joint effect among lonely and attractive participants (aOR, 1.70; 95% CI, 1.08-2.65). Use of gay telephone chatlines or online dating platforms mediated 30.5% of the association between loneliness and HIV acquisition risk, but did not mediate attractiveness and HIV acquisition risk. CONCLUSIONS: Our findings suggest that the provision of interventions focusing on mental health support and safer sex practices through gay telephone chatlines or online dating platforms is promising to help alleviate the HIV burden among gbMSM.

Sexual and gender minority youth (SGMY) are more likely to experience bullying and violence compared to the youth who do not identify as SGMY, leading to increased risk of poor mental and physical health outcomes, and poor academic performance. Few studies explore the entire range of bullying experienced by sexual and gender minority youth (SGMY). The purpose of this study was to qualitatively describe the ways in which SGMY experience bullying victimization. We conducted semi-structured interviews with a diverse sample of 20 SGMY aged 14-18 years (median age 16 years) recruited from online social media. The sample included 10 participants who identified as cisgender girls, 4 who identified as cisgender boys, 2 who identified as transgender, and 4 who identified as another gender identity. Ten participants identified as bisexual, six identified as lesbian, and four identified as gay. Findings indicated six common experiences of bullying among the participants: (a) verbal harassment; (b) gender policing; (c) physical violence; (d) sexual harassment; (e) treated as sexual perpetrators and deviants; and (f) and social exclusion. SGMY described how bullying victimization ranged from overt to concealed attitudes and behaviors, and they articulated how several forms of bullying are likely not experienced by heterosexual and cisgender youth. These results support findings from prior qualitative studies and suggest that efforts to address school-based bullying may benefit from a more complete awareness of the range of bullying victimization experienced by SGMY. Development of multi-item scales of bullying that reflect the six common experiences of bullying presented in this study would allow researchers to quantitatively explore the range of bullying behaviors experienced by SGMY, and would aid in the conceptualization and successful implementation of anti-bullying interventions.

Background Gay, bisexual, and other men who have sex with men (GBM) who engage in transactional sex (sex in exchange for drugs, money, or goods) experience increased risk of sexually transmitted infections (STI), including HIV. This study explored additional psychosocial and health-related factors associated with transactional sex among GBM. Methods Respondent-driven sampling was used to recruit GBM in Vancouver, Canada, from 2012 to 2015, with follow up every 6months until July2019. We examined factors associated with transactional sex using multivariable three-level mixed-effects modelling. Results Among 698 GBM, 22.1% reported ever receiving drugs, money, or goods for sex. Transactional sex was more likely to be reported by GBM who were younger (<30years) and who had lower incomes, less education, and insecure housing. GBM reporting transactional sex were more likely to report substance use (i.e. crystal methamphetamine, poppers, GHB, and non-steroid injection drugs) and higher risk sexual behaviours (i.e. more sex partners, sex party attendance, and condomless anal sex with serodifferent or unknown HIV status partners); however, they were no more likely to be living with HIV or to report a recent bacterial STI diagnosis. GBM who reported higher loneliness, anxiety, and cognitive escape were also more likely to report transactional sex. Conclusions More than one-fifth of GBM in Vancouver reported transactional sex and those who did were more likely to also experience psychosocial stressors, increased substance use, and higher risk sexual behaviours. Programs which consider the interconnections of personal, social, and structural challenges faced by GBM engaging in transactional sex are necessary to support improved mental, physical, and sexual health for these men.

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 preexposure prophylaxis (PrEP) use. METHOD: 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. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
