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
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…
From stigmatized status to responsibilized health behavior
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
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 …
Effect of depressive symptoms on health services utilization in the HIV and hepatitis C co-infected population in Canada
Depression is common among people living with HCV and HIV, which contributes to health services utilization (HSU). It is unknown whether successful HCV treatment affects this. We examined depressive symptoms and HSU in people co-infected with HIV-HCV and their association with sustained virologic response (SVR) during the direct-acting antiviral era. We predicted depressive symptoms by a random forest classifier in the Canadian Co-infection Cohor…
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…
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…
Navigating patterns of oral PrEP use
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…

Disjuncture between self-perceived and clinically assessed risk of HIV among gay, bisexual, and other men who have sex with men in Ontario and British Columbia, Canada
There is a disjuncture between self-perceived and clinically assessed risk of HIV. Some GBM may underestimate their HIV risk and clinical criteria may overestimate risk. Bridging these gaps requires efforts to increase HIV risk awareness in the community, and refinement of clinical assessments based on individualized discussions between the provider and the user
The rate of hepatitis C reinfection in Canadians coinfected with HIV and its implications for national elimination
Links Between Childhood Abuse, Insidious Trauma, and Methamphetamine Use Across the Lifespan Among Gay, Bisexual, and Other Men Who Have Sex with Men
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,…
Tobacco smoking and HIV-related immunologic and virologic response among individuals of the Canadian HIV Observational Cohort (Canoc)
We assessed the relationship between tobacco smoking and immunologic and virologic response among people living with HIV (PLWH) initiating combination antiretroviral therapy (cART) in the Canadian HIV Observational Cohort (CANOC). Positive immunologic and virologic response, respectively, were defined as ≥50 cells/mm3 CD4 count increase (CD4+) and viral suppression ≤50 copies/mL (VL+) within 6 months of cART initiation. Using multinomial regressi…
Understanding the Service Needs and Preferences of Men Who Have Sex with Men Who Use Crystal Methamphetamine in British Columbia, Canada
What other choices might I have made
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…
Community-Based Participatory Approaches to Knowledge Translation
Public health morality, sex, and Covid-19
Experts have warned that COVID-19 control measures may amplify health inequities among gay, bisexual, queer, and other men who have sex with men (GBM). For HIV-negative GBM, concerns have been raised as to how COVID-19 will disrupt access to HIV pre-exposure prophylaxis (PrEP). Our study offers empirical findings on these issues, drawing on in-depth interviews conducted with 25 HIV-negative GBM living in Ontario, Canada during the first wave of t…

Mortality among people living with HIV/Aids with non-small-cell lung cancer in the modern Haart Era
People living with HIV (PLWHA) with adequate access to modern combination antiretroviral therapy (cART) are living longer and experiencing reduced AIDS-related morbidity and mortality. However, increases in non-AIDS related conditions, such as certain cancers, have accompanied these therapeutic advances over time. As such, our study objective was to determine the impact of HIV on all-cause and lung cancer-specific mortality amongst PLWHA with dia…
Trends in discharges from the HIV/Aids ward at a tertiary Canadian Hospital from 2005 to 2014
Advances in HIV therapies have transformed HIV infection into a manageable chronic disease. Accordingly, hospital admission trends among people living with HIV may have evolved over time. This study describes discharge diagnoses from the dedicated HIV/AIDS ward at St. Paul's Hospital in Vancouver, Canada. A retrospective database review of admissions to the HIV/AIDS ward between 1 July 2005 and 30 June 2014 was conducted. Primary discharge diagno…

Factors associated with lost to follow-up after hepatitis C treatment delivered by primary care teams in an inner-city multi-site program, Vancouver, Canada
Awareness of, interest in, and willingness to pay for HIV pre-exposure prophylaxis among Canadian gay, bisexual, and other men who have sex with men
Is there a rural/urban gap in the quality of HIV care for treatment-naïve HIV-positive individuals initiating antiretroviral therapy in British Columbia
Rurally located people living with HIV (PLWH) face unique challenges associated with remoteness that may negatively affect their HIV care outcomes. The Programmatic Compliance Score (PCS) has been used previously as a quality of care metric, and is predictive of mortality for treatment-naïve individuals initiating combination antiretroviral therapy (cART). This study looked at whether the rurality of PLWH impacted their PCS. PCS was calculated fo…
