Substance Use and Incidence of Psychosis Diagnoses Among Gay, Bisexual, and Other Men Who Have Sex with Men Compared with Males from the General Population: A Matched Cohort Study from Metro Vancouver…
BACKGROUND: Gay, bisexual, and other men who have sex with men (GBM) report higher use of psychoactive substances, which may contribute to many adverse outcomes. METHOD: We examined the incidence of psychosis and associated substance use among GBM compared with males from the general male population. We analyzed data from 798 sexually active GBM from two cohort studies based in Vancouver, Canada, linking their survey data to administrative health…
Migration status, discrimination, and recent sexually transmitted infection testing among South Asian gay, bisexual, and other queer men living in Canada
“It’s Remarkably White”: A Qualitative Investigation of Race(ism) within Group Sex Events in a Canadian Context
Research on diversity within group sex communities in Canada tends to focus on gender, sexuality, and body size as indicators of inclusion and acceptance. Racial/ethnic diversity are notably absent from these discussions; in this study, we explored perceptions and experiences of race and racism in group sex spaces. We conducted two annual individual interviews with group sex participants living in southwestern Canada. Of our 20 participants, 40% …
It was Very Clear That We Were Not the Norm”: A Community-Based Qualitative Study of Experiences in the Legal System and Access to Justice Among Sexual Minority People in Western Canada
Despite rights-based advancements within Canada, sexual and gender minority people continue to face barriers when accessing and navigating the legal system across a wide range of legal issues. This study presents findings from 21 qualitative interviews conducted from 2020 to 2021 with sexual minority people in Western Canada exploring their experiences with the legal system. Findings presented in this paper focus on experiences of participants in…
Estimating the percentage and number of people with indications for HIV pre-exposure prophylaxis (PrEP) within two key populations, Canada, 2021
In Canada, the estimated number of people with PrEP indications among GBMSM and PWID far exceeded documented levels of use. Uptake of PrEP was lower among PWID compared to GBMSM. Efforts to improve PrEP access and uptake could help reduce HIV transmission in Canada
Disparities in healthcare, STI testing, and PrEP access among newcomer sexual minority men in Canada's three largest urban centers
Gay, bisexual, and other men who have sex with men (GBM) are more likely to be diagnosed with HIV and other sexually transmitted infections (STIs) compared with the general population. Although newcomers generally experience a health advantage in Canada compared with non‐immigrants and more established immigrants (i.e., healthy immigrant effect), they also experience disparities in access to healthcare services. These disparities, in turn, may le…
From stigmatized status to responsibilized health behavior: Gay, bisexual, and queer men's longitudinal narratives of shifts in PrEP-related stigma over time
For many gay, bisexual, and queer men (GBQM), using HIV pre-exposure prophylaxis (PrEP) has been extremely stigmatizing. Our objective was to trace changes in PrEP stigma within the accounts of GBQM in Canada, many with experience using this highly effective form of biomedical HIV prevention. We conducted annual longitudinal qualitative interviews with 46 HIV-negative GBQM living in Ontario or British Columbia, Canada. A total of 128 in-depth int…
Impact of “absolute” versus “relative” HIV risk communication on pre-exposure prophylaxis interest in Canada: A randomized survey
The way human immunodeficiency virus (HIV) acquisition risk is communicated can shape individuals’ perceptions and their interest in using pre-exposure prophylaxis (PrEP). This study examined two risk communication strategies among non-PrEP-using gay, bisexual, and other men who have sex with men (GBM) in Canada. In 2022, adult GBMs in Ontario and British Columbia completed an online survey and were randomly assigned to receive HIV risk messages …
Identifying Syndemic Factors and Their Effect on HIV Sexual Risk Behavior Among Gay, Bisexual and Other Men Who Have Sex with Men in Vancouver, Montreal and Toronto
We set out to identify syndemic factors associated with HIV sexual risk behavior among HIV-negative gay, bisexual and other men who have sex with men (GBM), and examine associations between syndemic factors and HIV sexual risk behaviors using models of co-occurring epidemics. We used baseline data from 1571 sexually active GBM from the Engage Cohort study, recruited using respondent-driven sampling in Montreal, Toronto, and Vancouver. We explored…
Willingness to disclose sexual orientation and gender identity on federal government surveys: A community-based research study with gay, bisexual, transgender, and queer men and nonbinary and Two-Spir…
These findings suggest that government datasets may significantly misclassify and underestimate the population size of 2S/GBTQ+ individuals. Persistent mistrust of government institutions within this community may exacerbate underreporting and non-disclosure, underscoring the need for research into methodologies that can enhance trust and improve the accuracy of population estimates. Researchers using existing government datasets should consider …
Innovative Community Policing Models in Response to Discrimination of Racialized Youth Who Use Drugs
Tense relations between police and racialized youth, especially those who use drugs, are ongoing concerns in Canada and other countries, with greater incidents of racial profiling and discrimination resulting in reduced trust and police legitimacy. While there have been calls for various forms of defunding police, some youth who use drugs (YWUDs) have highlighted the need for police to have stronger connections with the community to create better…
Attitudes of Gay, Bisexual, and Other Men Who Have Sex with Men (GBM) toward Their Use of Amphetamine-Type Stimulants and Relation to Reducing Use in Three Canadian Cities
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 lo…
Minority Stress, Psychological Distress, Sexual Compulsivity, and Avoidance-Based Motivations Associated with Methamphetamine Use Among Sexual Minority Men Living with HIV: Examining Direct and Indire…
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, sexu…
Different classes of crystal methamphetamine use are associated with psychological and sexually transmitted infection outcomes among gay, bisexual, and other men who have sex with men
Navigating patterns of oral PrEP use: A qualitative longitudinal study of gay, bisexual, and queer men's dynamic practices of pausing, on-demand, and stopping PrEP in Canada
The Canadian HIV pre-exposure prophylaxis (PrEP) guidelines recommend both daily and on-demand dosing for gay, bisexual, and queer men (GBQM), meeting additional risk criteria. However, limited research explored how GBQM implement pausing, on-demand, discontinuation, and resumption of PrEP, including the contextual factors affecting decision-making. Using a relationally situated implementation science framework, we examined how GBQM tailor PrEP u…
Ethno-racial variations in mental health symptoms among sexually-active gay, bisexual, and other men who have sex with men in Vancouver, Canada: A longitudinal analysis
Asian and Latino gbMSM reported decreased mental health symptoms compared to white participants. Asian and Latino gbMSM in Vancouver appear to manage multiple minority stressors without adversely affecting their mental health
HIV Treatment Optimism Moderates the Relationship between Sexual Risk Behavior and HIV Risk Perception among Urban HIV-negative Gay, Bisexual, and Other Men who have Sex With Men
To do so in a patient-centred way is not particularly lucrative: The effects of neoliberal health care on PrEP implementation and delivery
It's not as good as the face-to-face contact: A sociomaterialist analysis of the use of virtual care among Canadian gay, bisexual and queer men during the Covid-19 pandemic
The COVID-19 pandemic led to the widespread adoption of virtual care-the use of communication technologies to receive health care at home. We explored the differential impacts of the rapid transition to virtual care during the COVID-19 pandemic on health-care access and delivery for gay, bisexual and queer men (GBQM), a population that disproportionately experiences sexual and mental health disparities in Canada. Adopting a sociomaterial theoreti…
Conformity to Masculinity Norms and Mental Health Outcomes Among Gay, Bisexual, Trans, Two-Spirit, and Queer Men and Non-Binary Individuals
Homophobia and biphobia negatively impact the mental health of gay, bisexual, trans, Two-Spirit, and queer men and non-binary individuals (GBT2Q) and sexual and gender minority men, but little is known about the impact of gender-related oppression. The current study examines the impact of pressure to conform to masculine norms in Canada-based GBT2Q individuals. Specifically, the associations between (a) gender expression and pressure to be mascul…
Willingness and eligibility to donate blood under 12-month and 3-month deferral policies among gay, bisexual, and other men who have sex with men in Ontario, Canada
In Canada, gay, bisexual and other men who have sex with men (GBMSM) are a population that are willing to donate blood, if eligible, but have a history of ineligibility and deferrals due to concerns that their blood poses an increased risk of HIV entering the blood supply. Our objective was to examine the proportion of GBMSM who are willing and eligible to donate under the 12-month deferral policy (implemented in 2016) and the 3-month deferral po…
Treatment interruptions and community connectedness among gbMSM living with HIV in Metro Vancouver, Canada
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, B…
Unpacking racism during Covid-19: Narratives from racialized Canadian gay, bisexual, and queer men
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
Comparison of the burden of self-reported bacterial sexually transmitted infections among men having sex with men across 68 countries on four continents
Possible reasons for differences in self-reported STI diagnosis prevalence likely include different background prevalence for syphilis and syndromic management without proper diagnosis, and different diagnostic approaches for gonorrhea and chlamydia
Dominant Heterosexual Sexual Scripts in Emerging Adulthood: Conceptualization and Measurement
Sexual script research (Simon & Gagnon 1969 , 1986 ) bourgeoned following Simon and Gagnon's groundbreaking work. Empirical measurement of sexual script adherence has been limited, however, as no measures exist that have undergone rigorous development and validation. We conducted three studies to examine current dominant sexual scripts of heterosexual adults and to develop a measure of endorsement of these scripts. In Study 1, we conducted three …
You’re Gay, It’s Just What Happens”: Sexual Minority Men Recounting Experiences of Unwanted Sex in the Era of MeToo
Our grounded theory analysis derives from in-depth interviews conducted with 24 gay, bisexual, queer, and other men who have sex with men (GBM) living in Toronto, Canada, to understand their experiences of sexual coercion. Participants drew on discourse from the #MeToo movement to reconsider the ethics of past sexual experiences. The idea that gay or queer sex is inherently risky and unique from heterosexual relations made negotiating sexual safe…
The Positive Impact of Technology on Young Gay Men's Dating and Sexual Relationships in Canada: Results From a Focus Group Study
As technology use among gay men is increasing, investigation of the impact of technology on sexual and romantic relationships is warranted. The purpose of the current analysis was to explore the positive aspects of technology use among a community sample of young, Canadian gay men. Nine focus groups were held; transcripts were analyzed using Braun and Clarke's (2006) approach to thematic analysis. Participants described benefits related to findin…
Minority stressors and connectedness among urban gay, bisexual, and queer men
Organising care and community in the era of the ‘gay disease’: Gay community responses to HIV/Aids and the production of differentiated care geographies in Vancouver
Scholarship on the place of the HIV/AIDS crisis in urban geographies of sexual minority activism has powerfully insisted on the importance of community organising as a response to state and societal failures and to their homophobic, AIDS phobic and morally conservative underpinnings. This paper extends this scholarship by examining the urban social geographies of exclusion produced by such community organising efforts. It draws on the perspective…
Seroadaptive Strategies of Vancouver Gay and Bisexual Men in a Treatment as Prevention Environment
British Columbia's treatment as prevention policy has provided free access to highly active antiretroviral therapy (HAART) to all HIV-positive provincial residents since 1996. One outcome is an increase in HIV-positive gay and bisexual men (GBM) with suppressed viral loads. Previous cross-sectional analyses indicated that some Vancouver GBM now recognize condomless anal sex with men on HAART who report a suppressed viral load as a seroadaptive st…
It's not as good as the face-to-face contact: A sociomaterialist analysis of the use of virtual care among Canadian gay, bisexual and queer men during the Covid-19 pandemic
The COVID-19 pandemic led to the widespread adoption of virtual care-the use of communication technologies to receive health care at home. We explored the differential impacts of the rapid transition to virtual care during the COVID-19 pandemic on health-care access and delivery for gay, bisexual and queer men (GBQM), a population that disproportionately experiences sexual and mental health disparities in Canada. Adopting a sociomaterial theoreti…
A Latent Class Analysis of Seroadaptation Among Gay and Bisexual Men
Gay Men's Understanding and Education of New HIV Prevention Technologies in Vancouver, Canada
Effective rollout of HIV treatment-based prevention such as pre-exposure prophylaxis and treatment as prevention has been hampered by poor education, limited acceptability, and stigma among gay men. We undertook a thematic analysis regarding the education sources and acceptability of these New Prevention Technologies (NPTs) using 15 semistructured interviews with gay men in Vancouver, Canada, who were early adopters of NPTs. NPT education was der…
Links Between Childhood Abuse, Insidious Trauma, and Methamphetamine Use Across the Lifespan Among Gay, Bisexual, and Other Men Who Have Sex with Men: A Qualitative Analysis
Developmental and lifespan examinations of methamphetamine use among gay, bisexual, and other men who have sex with men (GBM) remain limited. We used a feminist trauma framework to examine potential links between childhood trauma, trauma-related stressors, and methamphetamine use among GBM. From June 2018 to October 2018, semi-structured interviews (N = 33) were conducted with GBM across British Columbia. Interviews focused on sexual experiences,…
I was just doing what a normal gay man would do, right: The biopolitics of substance use and the mental health of sexual minority men
Drawing on 24 interviews conducted with gay, bisexual, queer and other men who have sex with men (GBM) living in Toronto, Canada, we examined how they are making sense of the relationship between their mental health and substance use. We draw from the literature on the biopolitics of substance use to document how GBM self-regulate and use alcohol and other drugs (AODC) as technologies of the self. Despite cultural understandings of substance use …
What other choices might I have made: Sexual Minority Men, the PrEP Cascade and the Shifting Subjective Dimensions of HIV Risk
The PrEP Cascade is a dominant framework for investigating barriers to HIV pre-exposure prophylaxis (PrEP), an HIV prevention tool. We interviewed 37 PrEP users and 8 non-PrEP users in Ontario and British Columbia, Canada, about their decision-making through the Cascade. Participants were HIV-negative gay, bisexual, and queer men (GBQM). The data were analyzed using thematic analysis. PrEP decision-making was based on pragmatic considerations (lo…
Hosts as Gatekeepers for North American Gay and Bisexual Men's Private Group Sex Parties
Gay and bisexual men's (GBM) group sex parties are considered HIV risk environments due to their association with concurrent sexual partners, condomless anal sex, and polysubstance use. The possibility of group sex party hosts acting as gatekeepers to minimize risks has been suggested, but remains understudied. We analyzed qualitative data from 20 in-depth interviews with North American GBM who recently attended private group sex parties to deter…
Prevalence of HIV and sexually transmitted and blood-borne infections, and related preventive and risk behaviours, among gay, bisexual and other men who have sex with men in Montreal, Toronto and Vanc…
The three largest cities of Canada differed in HIV prevalence, STBBI testing and PrEP use among GBM. Our findings also suggest the need for scale-up of both PrEP and STI testing among GBM in Canada
Loneliness and self-rated physical health among gay, bisexual and other men who have sex with men in Vancouver, Canada
Background Due to stigma and discrimination, gay, bisexual and other men who have sex with men (gbMSM) potentially carry a heightened burden of loneliness. This analysis investigates loneliness among gbMSM and its relationship with self-rated physical health, along with the mediating effect of depression. Methods Participants were recruited using respondent-driven sampling into the Momentum Health Study (February 2012–February 2015) with follow-u…
Awareness of and intention to use an online sexually transmitted and blood-borne infection testing service among gay and bisexual men in British Columbia, two years after implementation
Objectives This study assessed gay, bisexual, and other men who have sex with men’s (GBMSM) awareness of and intention to use GetCheckedOnline, an online sexually transmitted and blood-borne infection (STBBI) testing service.

Longitudinal Event-Level Analysis of Gay and Bisexual Men’s Anal Sex Versatility: Behavior, Roles, and Substance Use
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 insert…
Event-Level Analysis of Anal Sex Roles and Sex Drug Use Among Gay and Bisexual Men in Vancouver, British Columbia, Canada
It's in Me to Give: Canadian Gay, Bisexual, and Queer Men's Willingness to Donate Blood If Eligible Despite Feelings of Policy Discrimination
Blood donation policies governing men who have sex with men have shifted significantly over time in Canada-from an initial lifetime ban in the wake of the AIDS crisis to successive phases of time-based deferment requiring periods of sexual abstinence (5 years to 1 year to 3 months). We interviewed 39 HIV-negative gay, bisexual, queer, and other sexual minority men (GBM) in Vancouver, Toronto, and Montreal to understand their willingness to donate…
Respondent-Driven Sampling With Youth Who Use Drugs: A Mixed Methods Assessment
Respondent-driven sampling (RDS) has been widely used for recruiting hard-to-sample populations, particularly men who have sex with men and people who inject drugs from large urban centers. The aim of this article was to examine the feasibility of using RDS among nonmetropolitan youth who use drugs. Between May 2017 and June 2018, RDS was used to recruit youth who use drugs, ages 16–30, in three nonmetropolitan Canadian cities. All participants c…
How Bisexual-Identified Men Use the Internet to Seek Sex with Other Men in Ontario: Factors Associated with HIV/STI Testing and Condom Use
Although seeking sex on the Internet may be associated with HIV risk for some men who have sex with men (MSM), little is specifically known about bisexual-identified MSM. Data were drawn from a community-based online survey of 1,830 MSM in Ontario. Among these MSM, 24.0% (n = 438) self-identified as bisexual. The authors examined (1) demographic, testing, and behavioral differences between bisexual- and other-identified MSM using chi-squared and …
Sexual Orientation Measurement, Bisexuality, and Mental Health in a Sample of Men Who Have Sex with Men in Vancouver, Canada
This cross-sectional study used a validated index (i.e., Hospital Anxiety and Depression Scale) to measure anxiety and depression (caseness score: ≥8) among men who have sex with men recruited via respondent-driven sampling in Vancouver, Canada (n=774), and investigated whether differences in mental health outcomes varied by sexual orientation measure (i.e., identity, attraction, behavior). Of the sample, 15.5% identified as bisexual, 33.4% repor…

Prevalence, type, and correlates of trauma exposure among adolescent men and women in Soweto, South Africa: Implications for HIV prevention
Nearly all adolescents in this study experienced trauma, with gendered differences in PTE types and correlates, but not prevalence. Exposure to PTEs were distributed along social and gendered axes. Among adolescent women, associations with depression and inconsistent condom use suggest pathways for HIV risk. HIV prevention interventions targeting adolescents must address the syndemics of trauma and HIV through the scale-up of gender-transformativ…
Seroadaptive Strategies of Gay & Bisexual Men (GBM) with the Highest Quartile Number of Sexual Partners in Vancouver, Canada
Pre-exposure Prophylaxis Awareness Among Gay and Other Men who have Sex with Men in Vancouver, British Columbia, Canada
Substance use, sexual behaviour and prevention strategies of Vancouver gay and bisexual men who recently attended group sex events
Group sex events are an epidemiologically important part of some gay and bisexual men's sexual culture in Canada. Associated with condomless anal intercourse and polysubstance use, such events have been cited as disproportionally contributing to HIV infection rates. We analysed questionnaire data from the Momentum Health Study in Vancouver, Canada, to understand substance use, sexual behaviour, psychosocial variables (Sexual Sensation Seeking, Se…

Sexual HIV risk among gay, bisexual and queer transgender men: Findings from interviews in Vancouver, Canada
Gay, bisexual, queer and other men who have sex with men are disproportionately affected by HIV in Canada. While up to 63% of transgender men identify as gay, bisexual or queer and report a variety of HIV sexual risk behaviours, transgender men are often overlooked within epidemiological HIV surveillance and research. While a growing body of research has begun to examine sexual risk for transgender gay, bisexual and queer men, most studies have b…

Hedge Your Bets: Technology's Role in Young Gay Men's Relationship Challenges
Technology is playing an increasingly pervasive role among young gay men in the process of meeting potential romantic or sexual partners. We investigated challenges posed by technology related to young gay men's relationships. Focus groups (n = 9) of young gay men aged 18-24 (n = 43) were transcribed verbatim, and thematic analysis was used to identify two major themes regarding challenges to relationship development and maintenance. Subthemes in…
Gender differences in prevalence and correlates of high sexual self-efficacy among adolescents in Soweto, South Africa: Implications for gender-sensitive research and programming
Sexual self-efficacy (SSE) - one's confidence in their ability to perform given sexual behaviours, has been shown to predict adolescents' HIV-prevention practices (e.g., Condom use). Few studies within sub-Saharan Africa, where HIV incidence and prevalence disproportionately affects young women, have examined gendered differences in SSE. We used multivariable logistic regression to identify correlates of high-SSE separately among adolescent men a…
Associations between sexual partner number and HIV risk behaviors: Implications for HIV prevention efforts in a Treatment as Prevention (TasP) environment
Previous research indicates that gay and bisexual men (GBM) have significantly more sexual partners than same-aged heterosexual men and women. As a result, some HIV intervention programs have focused on partner reduction. However, new research findings question the relevance of sexual partner number as a sexual risk measure for GBM given Treatment as Prevention (TasP) programs and new seroadaptive strategies which have led to lower GBM community …

A latent class analysis of substance use and culture among gay, bisexual and other men who have sex with men
Assessments of gay and bisexual men's substance use often obscures salient sociocultural and identity-related experiences related to how they use drugs. Latent class analysis was used to examine how patterns of substance use represent the social, economic and identity-related experiences of this population. Participants were sexually active gay and bisexual men (including other men who have sex with men), aged ≥ 16 years, living in Metro Vancouve…
Sexual Self-Efficacy and Gender: A Review of Condom Use and Sexual Negotiation Among Young Men and Women in Sub-Saharan Africa
Sexual self-efficacy (SSE), one's perceived control of or confidence in the ability to perform a given sexual outcome, predicts sexual behavior; however, important questions remain regarding whether gender modifies observed associations. In a comprehensive review of peer-reviewed HIV-prevention literature focusing on youth (ages 10 to 25) in sub-Saharan Africa, we measured and assessed the influence of SSE on condom use and sexual refusal, overal…
