Sexual minority men (SMM) experience anti-SMM stressors and have elevated rates of mental health issues compared to heterosexual men, such as depression. Importantly, strengths-based factors may directly increase wellbeing and provide a buffer against the detrimental effects of such stressors. In the present study, we integrated risk and strengths-based models to examine predictors of depression symptoms in a sample of 465 Canadian SMM across three time points using multilevel modeling.

Objectives: Lesbian, gay, and bisexual (LGB) and transgender and gender-diverse (TGD) people experience mental health disparities across the lifespan, yet little research has examined these trajectories into later adulthood; this study sought to fill this gap.

Method: We analyzed data from the Canadian Longitudinal Study on Aging (CLSA) using linear mixed models to compare longitudinal trajectories of mental health outcomes between gay/lesbian ( = 751), bisexual ( = 286), and heterosexual ( = 43,918) people, and between TGD ( = 24) and cisgender ( = 45,055) people.

Results: LGB adults reported significantly higher psychological distress and depression symptoms, and lower life satisfaction, compared to heterosexual people.

Sexual health literacy refers to the ability to find, understand, and use information and services to inform decisions and actions related to sexual health. Given the importance of sexual health literacy for improving health outcomes, it is prudent to identify sexual health literacy measures that can be used by healthcare providers, scholars and educators. To address this need, we used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses to conduct a systematic review.

This paper examines demographic, structural, and syndemic variables to map facilitators and barriers to accessing pre-exposure prophylaxis (PrEP) among gay, bisexual, and other men who have sex with men (GBM) in the three largest cities in Canada, Vancouver, Toronto, and Montreal. Focusing on factors in the later stages of the PrEP cascade, this study first performed a logistic regression analysis and reports adjusted odds ratios, then entered statistically significant social indicators into a network analysis to profile the interrelated and sometimes mutually reinforcing social conditions that shape inequitable access to PrEP among Canadian GBM. Barriers to accessing a gay-friendly health care provider (HCP) and financial barriers remain primary nodes associated with inequitable PrEP access.

Article Synopsis
  • The study examined the prevalence and factors associated with intimate partner violence (IPV) among gay, bisexual, and other men who have sex with men (GBM) in Canada from 2017 to 2022, revealing high rates of both IPV experience (31%) and perpetration (17%) among participants.
  • Data from 1455 GBM showed that during follow-up, IPV experience (6%) was more common than perpetration (4%), and certain factors like prior IPV experience and substance use significantly increased the risk of both experiencing and perpetrating IPV.
  • Despite the COVID-19 pandemic, rates of IPV remained stable over time, indicating a need for targeted interventions that address underlying determinants such as marginalization and substance use

Background And Purpose: Minority stressors have been linked with alcohol use among transgender and gender diverse (TGD); however, no ecological momentary assessment studies have examined daily links between minority stress and alcohol use specifically among TGD. This study examined gender minority stressors and resilience as predictors of same-day or momentary alcohol-related outcomes. Feasibility and acceptability of procedures were evaluated.

Aims: To cope with homonegativity-generated stress, gay, bisexual and other men who have sex with men (GBM) use more mental health services (MHS) compared with heterosexual men. Most previous research on MHS among GBM uses data from largely white HIV-negative samples. Using an intersectionality-based approach, we evaluated the concomitant impact of racialization and HIV stigma on MHS use among GBM, through the mediating role of perceived discrimination (PD).

  • The study examines how both distal (external) and proximal (internal) stressors affect alcohol use among gay, bisexual, and other men who have sex with men (GBM), considering the impact of anxiety and depression as mediators.
  • Researchers analyzed data from 2,449 GBM across major Canadian cities, using advanced statistical methods to identify relationships between stressors, mental health, and alcohol consumption.
  • The findings indicate that while distal stress leads to increased proximal stress and mental health issues, the direct effects on alcohol use are more complex, with anxiety and depression playing differing roles in alcohol consumption and problems.

  • Positive attitudes towards HIV treatment among gay, bisexual, and other men who have sex with men (GBM) may lead to riskier sexual behaviors that increase the chances of bacterial STIs.
  • A study involving 2449 GBM discovered a direct link between favorable HIV treatment attitudes and higher rates of current STI diagnoses, particularly through pathways of having more male anal sex partners and engaging in condomless anal sex.
  • The findings stress the need for healthcare providers to educate GBM about the risks attached to these attitudes in order to improve sexual health counseling, testing, and prevention strategies.

Introduction: Erectile dysfunction (ED) has been established as a comorbidity among men living with HIV, but comparisons by HIV serostatus of ED incidence in a longitudinal follow-up cohort of men are lacking. We sought to evaluate the incidence of ED spanning a period of 12 years in a longitudinal cohort of sexual minority men (SMM) living with and without HIV.

Methods: We analyzed ED incidence data for 625 participants in the longitudinal Multicenter AIDS Cohort Study from visits spanning October 2006 to April 2019.

  • The study investigated the attitudes of gay, bisexual, and other men who have sex with men (GBM) towards amphetamine use and factors influencing the reduction of such use over time in Canadian cities.
  • A total of 2,449 participants were recruited, with a significant percentage reporting past six-month amphetamine use, but only a small fraction felt they needed substantial help to reduce it.
  • The research found that those who perceived their amphetamine use as problematic were less likely to successfully reduce their consumption, highlighting the need for tailored interventions for individuals struggling with substance use perceptions.

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. Data from GBM ( = 2449) were used to fit three logistic regression models with lifetime bidirectional IPV as the outcome and four syndemic factors (i.

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.

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 theoretical perspective, we analysed 93 semi-structured interviews with GBQM (n = 93) in Montreal, Toronto and Vancouver, Canada, conducted between November 2020 and February 2021 (n = 42) and June-October 2021 (n = 51).

  • In Canada, gay, bisexual, and other men who have sex with men (GBMSM) historically faced deferrals from donating blood due to HIV risk concerns, but new shorter deferral policies have changed the landscape.
  • The study examined the willingness and eligibility of GBMSM to donate blood under both the 12-month and 3-month deferral policies using data from the #iCruise study, which surveyed 447 participants.
  • Results showed that under the 12-month policy, only 5.4% were both willing and eligible to donate blood, but this significantly improved to 12.3% under the 3-month policy, indicating a trend towards increased willingness based on factors like age, ethnicity, and
