Healthcare Provider Strategies and Approaches to Supporting People Living With HIV Who Are Experiencing HIV Treatment Disengagement in British Columbia, Canada
We conducted a strengths-based, qualitative study to elucidate the approaches and strategies utilized by healthcare providers (HCPs) to support HIV treatment engagement in British Columbia (BC), Canada. Healthcare providers (e.g., nurses, peer navigators, and pharmacists) across the province of BC were recruited through regional HIV programs and by word of mouth through purposive sampling strategies. An academic and community researcher co-conduc…
Retention in primary care among unstably housed residents of a low-income, inner-city neighborhood with a high prevalence of substance use and related disorders
We found that a primary healthcare model of care was successful in retaining over two-thirds of clients in primary healthcare after more than 18 months of follow-up. Additional supports for those diagnosed with alcohol use disorder are needed to retain them in care
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

Note-based analysis, guided b…
Examining the impacts of a syphilis awareness campaign among gay, bisexual, and other men who have sex with men (gbMSM) in British Columbia, Canada
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…

Methods: Eligible participants were GBMSM aged >15 years who reported sex wi…
Escape expectancies and sexualized substance use among gay, bisexual, and other men who have sex with men
McKirnan's Cognitive Escape Theory (1996) is often characterized by the hypothesis that drugs are used during sex by gay, bisexual, and other men who have sex with men (gbMSM) to relieve internal cognitive conflict over safe-sex norms and sexual desire. We examined how McKirnan's Cognitive Escape Scale (CES) is related to other widely used constructs relevant to sexualized substance use with hopes of better situating the theory within the evolvin…
Combination HIV Prevention Strategies Among Montreal Gay, Bisexual, and Other Men Who Have Sex with Men in the PrEP Era: A Latent Class Analysis
Pre-exposure prophylaxis (PrEP) became publicly available in Quebec for gay, bisexual and other men who have sex with men (GBM) in 2013. We used baseline data from Engage, a cohort of GBM recruited by respondent-driven sampling, to examine patterns of combination HIV prevention use among Montreal GBM since PrEP became available. Latent class analysis, stratified by HIV status, was used to categorize GBM by self-reported use of biomedical and beha…
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…
Factors associated with delayed and late ART initiation among people living with HIV in BC: Results from the engage study
We examined correlates of late and delayed initiation of antiretroviral therapy (ART) in British Columbia, Canada. From December 2013 to December 2015 we recruited treatment-naïve people living with HIV who initiated ART within the previous year. 'Late initiation' was defined as CD4 cell count ≤500 cells/μL at ART initiation and 'delayed initiation' as ≥1 year between HIV diagnosis and initiation. Multivariable logistic regression assessed indepe…
“Condoms are … like public transit. It’s something you want everyone else to take”: Perceptions and use of condoms among HIV negative gay men in Vancouver, Canada in the era of biomedical and seroadap…
These findings indicate that notions of "safety" and "risk" based on consistent condom use are eroding as other modes of prevention gain visibility. Community-based and public health interventions will need to shift prevention messaging from advocacy for universal condom use toward combination prevention in order to meet gay men's current prevention needs. Interventions should advance gay men's communication and self-advocacy skills in order to o…
HIV leadership programming attendance is associated with PrEP and PEP awareness among young, gay, bisexual, and other men who have sex with men in Vancouver, Canada
Younger GBM, who are disproportionately affected by the HIV epidemic, are less aware of new prevention technologies than older GBM, but attending peer-based HIV-leadership programs ameliorates age-disparities in HIV-prevention knowledge and treatment optimism

Gendered HIV risk patterns among polygynous sero-discordant couples in Uganda
Stable serodiscordant relationships and sexual concurrency are pathways that contribute to the HIV epidemic in sub-Saharan Africa. However whether polygyny imparts the same risks as informal concurrent relationships remains an open research question. Using data collected at enrollment from a cohort study of sero-discordant couples, this analysis investigates how polygynous relationships differ from those involving only a single female spouse and …
Home is where the Haart is: An examination of factors affecting neighbourhood perceptions among people with HIV/Aids on antiretroviral therapy
Understanding the neighbourhood perceptions of individuals living with HIV in urban and non-urban areas may help identify potential barriers to uptake and effectiveness of therapy. We evaluate how neighbourhood perceptions are influenced by socio-economic factors, such as food security and stable housing and other explanatory variables, among individuals receiving highly active antiretroviral therapy (HAART) in British Columbia. Neighbourhood per…

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 …
Trends in Awareness and Use of HIV PrEP Among Gay, Bisexual, and Other Men who have Sex with Men in Vancouver, Canada 2012–2016
HIV Testing Among a Representative Community Sample of Gay, Bisexual, and Other Men Who Have Sex with Men in Vancouver, Canada
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…
