It is time to mobilize suicide prevention for sexual and gender minorities in Canada

Suicide is a significant health issue among sexual and gender minority adults (SGMA); yet, there are no tailored suicide prevention programs for these marginalized populations in Canada. We hosted two world cafés with community leaders, health professionals, policymakers, and researchers to identify recommendations for mobilizing SGMA-focused suicide prevention programs. We identified five priorities: (1) make society safer for sexual and gender minorities; (2) decrease barriers to mental health services; (3) support community-driven and community-based interventions; (4) increase suicide knowledge and reduce stigma; (5) expand the knowledge base on SGMA suicide. In the absence of a national Canadian SGMA suicide prevention policy, these priorities provide a starting point in addressing SGMA suicide inequities by advancing SGMA-tailored interventions.

Disparities in the prevalence of cigarette smoking among bisexual people: a systematic review, meta-analysis and meta-regression

OBJECTIVE

To review the bisexual-specific prevalence and likelihood of cigarette smoking relative to lesbian/gay and heterosexual individuals.

DATA SOURCES

We searched MEDLINE, PsycInfo, CINAHL, Scopus and LGBT Life databases (from 1995 to September 2019) for studies reporting cigarette smoking among bisexuals versus their comparators.

STUDY SELECTION

Observational, quantitative, peer-reviewed studies providing estimates for lifetime, past 30 days or current cigarette smoking among bisexuals and any of the two comparators were selected.

DATA EXTRACTION

Data on sexual orientation groups, cigarette smoking, sample type and mechanism, data collection mode, country and median year, as well as gender and age groups were extracted.

DATA SYNTHESIS

Random-effects meta-analysis was used to estimate the pooled OR (95% CIs) of cigarette smoking. Meta-regression was used to examine the difference in the prevalence of cigarette smoking by study and sample characteristics. Of 4663 unduplicated records, 47 unique studies were included (14, 23 and 22 studies on lifetime, past 30 days and current cigarette smoking, respectively). Compared with lesbians/gays and heterosexuals, bisexuals were 1.25 (1.15 to 1.37) and 2.18 (1.84 to 2.59) times more likely to report lifetime smoking, 1.17 (1.08 to 1.27) and 2.49 (2.20 to 2.83) times more likely to report past 30 days smoking and 1.19 (1.00 to 1.43) and 2.26 (1.97 to 2.59) times more likely to report current smoking. Gender was a significant covariate in the meta-regression models.

CONCLUSIONS

Cigarette smoking was more prevalent among bisexuals than lesbians/gays and heterosexuals, with the estimates showing a greater magnitude among bisexual women relative to all other sexual orientation/gender subgroups.

Prevalence of Exposure to Sexual Orientation Change Efforts and Associated Sociodemographic Characteristics and Psychosocial Health Outcomes among Canadian Sexual Minority Men

OBJECTIVE

Sexual orientation change efforts (SOCE), or "conversion therapy," are pseudoscientific practices intended to suppress or deny sexual attraction to members of the same gender/sex. There are currently no data available to inform estimates of the prevalence of SOCE exposure in Canada. The objective of this study is therefore to describe the prevalence, social-demographic correlates, and health consequences of SOCE among Canadian sexual minority men.

METHODS

Sex Now 2011 to 2012 was a cross-sectional nonprobability survey of Canadian sexual minority men. Respondents were asked about lifetime SOCE exposure. We estimated prevalence of SOCE exposure by sociodemographic characteristics and examined psychosocial health outcomes among those exposed to SOCE.

RESULTS

Of N = 8,388 respondents, 3.5% (95% confidence interval, 3.2% to 4.1%) reported having ever been exposed to SOCE. Exposure to SOCE was higher among gay men (as compared with bisexual men), transgender respondents (as compared with cisgender respondents), those who were "out" about their sexuality (as compared with those who were not "out"), Indigenous men (as compared with White men), other racial minorities (as compared with White men), and those earning a personal income <$30,000 (as compared with those earning ≥$60,000 CAD). Exposure to SOCE was positively associated with loneliness, regular illicit drug use, suicidal ideation, and suicide attempt.

CONCLUSIONS

SOCE exposure remains prevalent and associated with substantial psychosocial morbidity among sexual minority men in Canada. All levels of government in Canada should consider action to ban SOCE. SOCE survivors likely require intervention and support from the Canadian health-care system.

The Social Geography of Partner Selection in Toronto, Canada: A Qualitative Description of "Convection Mixing"

The geographic distribution of sexually transmitted infections reflects the underlying social process of sexual partner selection. This qualitative study explored the social geography of partner selection among sexual minority men and used the results to develop a mid-range theory of STI transmission. In-depth interviews with 31 sexual minority men who lived, worked, or socialized in Toronto, Canada, occurred in June and July 2016. Participants were asked how they found sexual partners and reconstructed their egocentric sexual networks for the previous 3 months. Participants described an iterative process of partner selection involving intention (sex versus dating), connecting with community, and selecting a partner based on intersecting partner characteristics (external, internal, and emergent feelings when interacting with potential partners) and personal preferences. Geography influenced partner selection three ways: (1) participant search patterns maximized the number of potential partners in the shortest distance possible; (2) the density of sexual minority men in a participant's community directly impacted participant's social and sexual isolations; and (3) geosexual isolation influenced sexual mixing patterns. Participants described "convection mixing," where assortative urban mixing nested within disassortative suburban mixing resulted in movement from the suburbs to downtown and back to the suburbs. We theorize that convection mixing may be contributing to the persistence of STI epidemics in core and outbreak areas by creating STI reservoirs outside of, and connected to, core and outbreak areas.

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.

Methods

A cross-sectional study was conducted two years after launch among GBMSM > 18 years of age in British Columbia, Canada. Participants were recruited through community venues, clinics, websites, and apps.

Results

Of 1272 participants, 32% were aware of GetCheckedOnline. Gay identity, regularly testing at an STBBI clinic, being out to one’s healthcare provider, attending GBMSM community venues, and frequent social media use were associated with awareness. Among participants who were aware but had not used GetCheckedOnline, knowing GetCheckedOnline users, using social media, not knowing where else to test, and not wanting to see a doctor were associated with intention to use GetCheckedOnline.

Conclusion

Early promotion of GetCheckedOnline resulted in greater awareness among those connected to GBMSM.

From silos to buckets: a qualitative study of how sexual health clinics address their clients' mental health needs

OBJECTIVES

To describe the current constraints, facilitators, and future prospects for addressing mental health and substance use (MHSU) concerns within sexual health clinics in two cities in British Columbia, Canada.

METHODS

We conducted in-depth interviews with 22 providers (14 nurses, 3 physicians, 3 administrators, 2 other health professionals) from six sexual health clinics.

RESULTS

Providers consistently affirmed that MHSU-related concerns co-occur with sexual health concerns among clients presenting to sexual health clinics. Three factors constrained the providers' abilities to effectively address MHSU service needs: (1) clinic mandates or funding models (specific to sexually transmitted infections (STI)/HIV or reproductive health); (2) "siloing" (i.e., physical and administrative separation) of services; and (3) limited familiarity with MHSU service referral pathways. Mental health stigma was an additional provider-perceived barrier for sexual health clinic clients. The low barrier, "safe" nature of sexual health clinics, however, facilitated the ability of clients to open up about MHSU concerns, while the acquired experiences of sexual health nurses in counselling enabled clinicians to address clients' MHSU needs. In response to this context, participants described actionable solutions, specifically co-location of sexual health and MHSU services.

CONCLUSION

Sexual health clinicians in British Columbia generally affirm the results of previous quantitative and client-focused research showing high rates of MHSU-related needs among sexual health clinic clients. Providers prioritized specific short-term (referral-focused) and long-term (healthcare re-organization, co-location of sexual and MHSU services) solutions for improving access to MHSU services for those using sexual health services.

Stigma in the bereavement experiences of gay men who have lost a partner to suicide

Despite the high prevalence of suicide in gay communities, the impact of suicide on surviving male partners is poorly understood. This article presents a qualitative case study of two gay men who lost a partner to suicide and explores how stigma may shape gay men's bereavement experiences. Data were collected using photovoice methods and analysed using a thematic approach. Five themes were inductively derived: (1) trying to prevent the inevitable; (2) guilty of keeping secrets; (3) dreams shattered by suicide; (4) abandoned and alone in grief; and (5) a lonesome road to recovery. Within each theme, the article indentifies how stigma-related challenges associated with suicide, mental illness and minority sexual identity shaped gay men's bereavement experiences. Practice and policy implications are discussed, including how the provision of tailored clinical and peer supports can assist gay men in the bereavement of a same-sex partner to suicide. The findings detailed in this study highlight the need for interventions to de-stigmatise mental illness and suicide within and outside the gay community.

Sexual and Gender Minorities' Readiness and Interest in Supporting Peers Experiencing Suicide-Related Behaviors

Background: Gatekeeper training is a widely recommended suicide prevention intervention that encourages the development of knowledge and the identification and support of those at risk of suicide. Yet, this strategy has not been implemented among sexual and gender minorities (SGM), a group at high risk of suicide. Aim: The aim of this study was to describe the readiness and interest of SGM in supporting peers experiencing suicide-related behaviors. Method: We analyzed data from an online cross-sectional survey of Canadian SGM (n = 2778). Results: In total, 90% of participants had ≥1 SGM peer with depression, and 73% had ≥1 SGM peer who had previously attempted suicide; 74% said they knew what to do to support a peer experiencing suicide risk, and 77% indicated they knew where to refer them. Furthermore, 94% were interested in learning how to recognize signs of suicidality, while 95% were interested in learning skills to support a peer struggling with suicidality and 81% of those indicated a preference to learn these skills online. Limitations: The study used a nonprobability sample and cross-sectional design. Conclusion: SGM are largely interested in learning suicide prevention skills and, as such, more resources are needed to implement and scale up evidence-based approaches for gatekeeper training among SGM.

A cohort study comparing rate of repeat testing for sexually transmitted and blood-borne infections between clients of an internet-based testing programme and of sexually transmitted infection clinics in Vancouver, Canada

Objectives

Internet-based sexually transmitted and blood-borne infection (STBBI) testing services reduce testing barriers through bypassing face-to-face clinical encounters, potentially enabling clients at ongoing sexual risk to test more frequently. To our knowledge, this hypothesis has not been previously tested. We compared the frequency of repeat testing between Vancouver-based clients of GetCheckedOnline (GCO)—an internet-based STBBI testing service in British Columbia, Canada—and clients of three sexually transmitted infection (STI) clinics in Vancouver for 29 months after GCO launched.

Methods

An administrative data cohort (n=19 497) was assembled using GCO, clinical and laboratory databases. We included all individuals who tested for HIV, gonorrhoea/chlamydia, syphilis or hepatitis C at three STI clinics or using GCO, between September 2014 and February 2017. The rate of repeat testing (>30 days after first episode) was compared between clients who used GCO at least once and those who tested only in STI clinics. Poisson regression was used to generate relative rate (RR) for repeat testing, with adjustment for age, gender/sexual orientation, risk factors (eg, history of STI diagnosis) and rate of testing before GCO launched.

Results

1093 GCO clients were identified, of whom 434 (40%) had repeat test episodes; 8200/18 404 (45%) of clinic clients tested more than once. During the 29-month analysis period, GCO clients repeat tested 1.87 times per person-year, whereas clinic clients repeat tested 1.53 times per person-year, resulting in a crude RR of 1.22 (95% CI: 1.14 to 1.31). Adjustment for covariates increased the RR to 1.26 (95% CI: 1.15 to 1.37).

Conclusions

In this cohort, individuals using internet-based STBBI testing had a rate of repeat testing 22% greater than clinic-based clients. This effect was increased after adjusting for characteristics associated with higher test frequency. The online interface of GCO may facilitate more frequent testing and may therefore contribute to earlier STBBI diagnosis.

Predicting the impact of clustered risk and testing behaviour patterns on the population-level effectiveness of pre-exposure prophylaxis against HIV among gay, bisexual and other men who have sex with men in Greater Vancouver, Canada

Pre-exposure prophylaxis (PrEP) has the potential to greatly reduce transmission of HIV. However, significant questions remain around how behavioural factors may influence its impact within target populations. We used a 2014 sexual behaviour survey to modify and recalibrate a mathematical model of HIV infection dynamics within the population of gay, bisexual and other men who have sex with men (GBMSM) in the Greater Vancouver area of British Columbia, Canada. We performed a clustering analysis on the survey data to divide the population into categories associated with their reported risk of HIV exposure as well as their reported testing habits and attitudes towards PrEP. We found a positive association between reported risk and testing behaviour and level of awareness/interest in PrEP. Using the cluster groups to structure the population, we then estimated the impact of PrEP on HIV transmission in our study population. We found that the association between behaviour and interest in PrEP substantially boosted the population-level effectiveness of PrEP. Within our model, if PrEP adoption was unrelated to risk and testing, an additional 206 (95% credible interval 5-261), new infections representing 15% of total infections are predicted to occur among GBMSM over ten years, compared to where PrEP is adopted by individuals according to their level of interest. Our results underscore the importance of incorporating behavioural data into models when predicting the impact of future public health interventions.

Using Photovoice to Understand Suicidality Among Gay, Bisexual, and Two-Spirit Men

This study explored the drivers of suicidality from the perspectives of gay, bisexual, and two-spirit men (GB2SM) with a history of suicidality. Twenty-one GB2SM participated in this photovoice study taking photographs to depict and discuss their previous suicidality. Data were collected from in-depth individual interviews in which participants discussed their photographs and in turn offered verbal/narrative accounts of suicidality. Drawing on intersectionality, analyses of the photographs and interview data revealed three interconnected themes. First, adverse childhood events and negative adolescent experiences were described as the root causes of mental health struggles and suicidality. Second, violence and homophobia had disrupted these men's education and employment opportunities and some participants detailed how their lack of capital and challenges for maintaining employment shaped their suicidality. Third, a sociality of stigma and sense of isolation compounded experiences of suicidality. The three themes overlapped and were shaped by multiple intersectional axes including sexuality, class, ethnicity, and mental health status. The findings have implications for services and health professionals working with GB2SM who need to thoughtfully consider life-course trajectories and multiple social axes when assessing and treating GB2SM experiencing suicidality. More so, because these factors relate to social inequities, structural and policy changes warrant targeted attention.

Suicide Prevention From the Perspectives of Gay, Bisexual, and Two-Spirit Men

Although gay, bisexual, and two-spirit men (GBTSM) experience high rates of suicidality, there have been few empirical studies of prevention initiatives and policies that could address or reverse this major social problem. This article reports on a photovoice study of 29 GBTSM who had a history of suicidality or lost a fellow GBTSM to suicide. We focused our analysis on participants' perspectives on suicide prevention. Participants described four key considerations for GBTSM suicide prevention: (a) recognizing and addressing enduring homophobia, biphobia, and mental illness stigma; (b) provision of low-barrier, long-term, and GBTSM-affirming counseling; (c) de-isolation through peer support and community connection; and (d) fostering creativity and cultural resilience. By engaging GBTSM affected by suicide through photographs that depict their experiences and points of view, in this study, we offer concrete recommendations to reduce suicidality among GBTSM.

Conceptualizing Geosexual Archetypes: Mapping the Sexual Travels and Egocentric Sexual Networks of Gay and Bisexual Men in Toronto, Canada

Six geosexual archetypes were identified: hosters, house-callers, rovers, privates, travellers, and geoflexibles, each with different characteristic profiles. Prioritizing interventions to hosters, rovers, and geoflexibles may reduce sexually transmitted infection transmission.

Supplemental digital content is available in the text.

Background

There are complex, synergistic, and persistent sexually transmitted infection (STI) epidemics affecting gay, bisexual and other men who have sex with men (gbMSM) in every major urban centre across North America. We explored the spatial architecture of egocentric sexual networks for gbMSM in Toronto, Canada.

Methods

Our integrative mixed methods study included in-depth interviews with 31 gbMSM between May and July 2016. During interviews, participants mapped their egocentric sexual network for the preceding 3 months geographically. At the end, a self-administered survey was used to collect sociodemographic characteristics, online technology use, and STI testing and history.

Results

We identified 6 geosexual archetypes: hosters, house-callers, privates, rovers, travellers, and geoflexibles. Hosters always, or almost always (≥80%), hosted sex at their home. House-callers always, or almost always (≥80%), had sex at their partner’s home. Rovers always or almost always (≥80%) had sex at public venues (eg, bath houses, sex clubs) and other public spaces (eg, parks, cruising sites). Privates had sex in private—their own home or their partner's (part hoster, part house-caller). Travellers had sex away from their home, either at a partner’s home or some other venue or public space (part house-caller, part rover). Geoflexibles had sex in a variety of locations—their home, their partner’s home, or public venues. All hosters and rovers, and to a lesser extent, geoflexibles, reported a history of syphilis and human immunodeficiency virus.

Conclusions

Prioritizing interventions to hosters, rovers, and geoflexibles may have an important impact on reducing STI transmission.

Assessing the Impact of a Social Marketing Campaign on Program Outcomes for Users of an Internet-Based Testing Service for Sexually Transmitted and Blood-Borne Infections: Observational Study

BACKGROUND

While social marketing (SM) campaigns can be effective in increasing testing for sexually transmitted and blood-borne infections (STBBIs), they are seldom rigorously evaluated and often rely on process measures (eg, Web-based ad click-throughs). With Web-based campaigns for internet-based health services, there is a potential to connect campaign process measures to program outcomes, permitting the assessment of venue-specific yield based on health outcomes (eg, click-throughs per test).

OBJECTIVE

This study aims to evaluate the impact of an SM campaign by the promotional venue on use and diagnostic test results of the internet-based STBBI testing service GetCheckedOnline.com (GCO).

METHODS

Through GCO, clients create an account using an access code, complete a risk assessment, print a lab form, submit specimens at a lab, and get results online or by phone. From April to August 2015, a campaign promoted GCO to gay, bisexual, and other men who have sex with men in Vancouver, Canada. The campaign highlighted GCO's convenience in 3 types of promotional venues-location advertisements in print or video displayed in gay venues or events, ads on a queer news website, and ads on geosocial websites and apps. Where feasible, individuals were tracked from campaign exposures to account creation and testing using venue-specific GCO access codes. In addition, Web-based ads were linked to alternate versions of the campaign website, which used URLs with embedded access codes to connect ad exposure to account creation. Furthermore, we examined the number of individuals creating GCO accounts, number tested, and cost per account created and test for each venue type.

RESULTS

Over 6 months, 177 people created a GCO account because of the campaign, where 22.0% (39/177) of these completed testing; the overall cost was Can $118 per account created and Can $533 per test. Ads on geosocial websites and apps accounted for 46.9% (83/177) of all accounts; ads on the news website had the lowest testing rate and highest cost per test. We observed variation between different geosocial websites and apps with some ads having high click-through rates yet low GCO account creation rates, and vice versa.

CONCLUSIONS

Developing mechanisms to track individuals from Web-based exposure to SM campaigns to outcomes of internet-based health services permits greater evaluation of the yield and cost-effectiveness of different promotional efforts. Web-based ads with high click-through rates may not have a high conversion to service use, the ultimate outcome of SM campaigns.

Post-test comparison of HIV test knowledge and changes in sexual risk behaviour between clients accessing HIV testing online versus in-clinic

Objective

Internet-based HIV testing offers the potential to address privacy-related barriers to testing and increase frequency of testing but may result in missed opportunities related to sexual health education and prevention that typically occur in face-to-face encounters. In this study, we assessed the HIV test knowledge and sexual risk behaviour of clients testing for HIV through GetCheckedOnline, an internet-based sexually transmitted and bloodborne infection testing platform inclusive of HIV testing, in comparison to clients testing through a large sexual health clinic.

Methods

We concurrently recruited GetCheckedOnline clients and clinic clients from Vancouver, Canada, over the course of a 10-month period during 2015–2016. Participants completed baseline and 3-month questionnaires, anonymous and online. A six-item score was used to estimate knowledge of HIV test concepts typically conveyed during an HIV pretest encounter in a clinic. We used multiple regression to estimate associations between testing modality (online vs clinic based) and two outcomes—HIV test knowledge and change in condom use pre/post-test—with adjustment for relevant background factors.

Results

Among 352 participants, online testers demonstrated higher HIV post-test knowledge than clinic-based testers (mean score 4.65/6 vs 4.09/6; p<0.05); this difference was reduced in adjusted analysis (p>0.05). Men who have sex with men, clients with a university degree, those who have lived in Canada >10 years and English speakers had higher HIV post-test knowledge (p<0.05). Eighteen per cent of online testers and 10% of clinic-based testers increased condom use during the 3 months post-test (p>0.05).

Conclusions

In this comparative study between online and clinic-based testers, we found no evidence of decreased HIV test knowledge or decreased condom use following HIV testing through GetCheckedOnline. Our findings suggest that with careful design and attention to educational content, online testing services may not lead to missed opportunities for HIV education and counselling.

Effects of Multiple Forms of Information Bias on Estimated Prevalence of Suicide Attempts According to Sexual Orientation: An Application of a Bayesian Misclassification Correction Method to Data From a Systematic Review

Multiple epidemiologic studies demonstrate a disparity in suicide risk between sexual minority (lesbian, gay, bisexual) and heterosexual populations; however, both "exposure" (sexual minority status) and outcome (suicide attempts) may be affected by information bias related to errors in self-reporting. We therefore applied a Bayesian misclassification correction method to account for possible information biases. A systematic literature search identified studies of lifetime suicide attempts in sexual minority and heterosexual adults, and frequentist meta-analysis was used to generate unadjusted estimates of relative risk. A Bayesian model accounting for prior information about sensitivity and specificity of exposure and outcome measures was used to adjust for misclassification biases. In unadjusted frequentist analysis, the relative risk of lifetime suicide attempt comparing sexual minority with heterosexual groups was 3.38 (95% confidence interval: 2.65, 4.32). In Bayesian reanalysis, the estimated prevalence was slightly reduced in heterosexual adults and increased in sexual minority adults, yielding a relative risk of 4.67 (95% credible interval: 3.94, 5.73). The disparity in lifetime suicide attempts between sexual minority and heterosexual adults is greater than previously estimated, when accounting for multiple forms of information bias. Additional research on the impact of information bias in studies of sexual minority health should be pursued.

A Systematic Review and Meta-Analysis of Disparities in the Prevalence of Suicide Ideation and Attempt Among Bisexual Populations

Sexual minorities are at increased risk of suicide; however, it is unclear whether there are within-sexual minority differences in risk across specific sexual identities-notably between bisexual and lesbian/gay subgroups. We therefore conducted a systematic review and meta-analysis to quantify associations between bisexual identity and self-reported suicide ideation and attempt and the moderation of these associations by gender/sex, age, sampling strategy, and measurement of sexuality. Abstracts and full texts were independently screened by two reviewers, resulting in a total of 46 studies that met inclusion criteria and reported 12-month or lifetime prevalence estimates for suicide ideation or attempt. A consistent gradient was observed across all four outcomes, whereby bisexual respondents reported the highest proportion of suicide ideation or attempt, lesbian/gay respondents the next highest proportion, and heterosexual respondents the lowest proportion. Random-effects meta-analysis comparing bisexual individuals with lesbian/gay individuals yielded odds ratios (ORs) ranging between 1.22-1.52 across the four outcomes examined. Between-study variability in ORs was large. Thirty-one percent of heterogeneity was explained by sample type (e.g., probability vs. non-probability) and 17% by gender/sex. ORs were consistently larger for women (range: 1.48-1.95, all statistically significant at p < .05) than for men (range: 1.00-1.48, all p > .05), suggesting that gender/sex moderates the association between bisexual identity and suicide risk. Within-sexual minority differences in suicide risk may be attributed to structural and interpersonal experiences of monosexism, bisexual erasure and invisibility, or lack of bisexual-affirming social support, each of which may be experienced differently across gender/sex identities.

Syndemic Characterization of HCV, HBV, and HIV Co-infections in a Large Population Based Cohort Study

BACKGROUND

Limited data are available on HBV, HCV, and HIV co-infections and triple infection. We characterized co-occurrence of HIV, HBV, and HCV infections at the population level in British Columbia (BC) to identify patterns of predisposing factors unique to co-infection subgroups.

METHODS

We analyzed data from the BC Hepatitis Testers Cohort, which includes all individuals tested for HCV or HIV in BC between 1992 and 2013, or included in provincial public health registries of HIV, HCV, HBV, and active tuberculosis. Individuals were classified as negative, mono-, and co-infection groups based on HIV, HBV, and HCV status. We evaluated associations between risk factors (injection drug use, sexual orientation etc.) and co-infection groups using multivariate multinomial logistic regression.

FINDINGS

Of a total of 1,376,989 individuals included in the analysis, 1,276,290 were negative and 100,699 were positive for HIV, HBV, and/or HCV. Most cases (91,399, 90.8%) were mono-infected, while 3991 (4.0%) had HBV/HCV, 670 HBV/HIV (0.7%), 3459 HCV/HIV (3.4%), and 1180 HBV/HCV/HIV (1.2%) co-infection. Risk factor and demographic distribution varied across co-infection categories. MSM classification was associated with higher odds of all HIV co-infection groups, particularly HBV/HIV (OR 6.8; 95% CI: 5.6, 8.27), while injection drug use was most strongly associated with triple infection (OR 64.19; 95% CI: 55.11, 74.77) and HIV/HCV (OR 23.23; 95% CI: 21.32, 25.31).

INTERPRETATION

Syndemics of substance use, sexual practices, mental illness, socioeconomic marginalization, and co-infections differ among population groups, highlighting avenues for optimal composition and context for health services to meet each population's unique needs.

Healthcare engagement among gay and bisexual men with recent suicide ideation or attempts

Gay and bisexual men experience elevated rates of suicide ideation and attempts, as compared with heterosexual men, but face unique barriers in accessing health services. In this context, the present study sought to describe rates of health care engagement among gay and bisexual men with a recent history of suicide ideation or attempts. An anonymous online survey was conducted with 7,872 Canadian gay and bisexual men in 2014-2015. The sample was restricted to characterize patterns of mental health care engagement among respondents who reported suicide ideation or attempts in the previous 12 months. "Engagement" was defined as having discussed mental health concerns (depression, substance use, or suicide) with a provider in the previous 12 months. Rates and correlates of engagement were estimated. Nineteen percent of men reported suicide ideation or attempts in the previous 12 months, of whom 58% had discussed mental health concerns with a provider. Older age, larger social support networks, and being out to a health care provider about one's sexuality were all positively associated with mental health care engagement. Among those who had not engaged with the health care system, 88% had some contact with a provider in the previous 12 months. One-third of these men accessed care through a provider other than their family doctor. Drawing on lessons learned from the HIV crises, collaborations between gay and bisexual community organizations and decision-makers within the health system are needed to address elevated rates of suicide ideation and attempts affecting sexual minorities.

Constructing and Expanding Suicide Narratives From Gay Men

In this study, we document life stories of gay men who attempted suicide as adults. Our goal is to expand the collection of narratives used to understand this persistent health inequity. We interviewed seven adult gay men, each of whom had attempted suicide two to four times, and identified five narratives. Pride narratives resist any connection between sexuality and suicide. Trauma-and-stress narratives enable coping through acknowledgment of sexual stigma as a fundamental trauma and cause of subsequent stress and suicidal thoughts. Memorial narratives prevent suicide by maintaining a strong sense of "permanent" identity. Outing narratives demand that the listener confronts the legacy of unjust practices of homosexual surveillance and "outing," which historically resulted in gay suicides. Finally, postgay narratives warn of the risk of suicide among older generations of gay men who feel erased from the goals of modern gay movements. Sexual identity concealment or invisibility featured prominently in all five narratives.

Using Geosocial Networking Apps to Understand the Spatial Distribution of Gay and Bisexual Men: Pilot Study

BACKGROUND

While services tailored for gay, bisexual, and other men who have sex with men (gbMSM) may provide support for this vulnerable population, planning access to these services can be difficult due to the unknown spatial distribution of gbMSM outside of gay-centered neighborhoods. This is particularly true since the emergence of geosocial networking apps, which have become a widely used venue for meeting sexual partners.

OBJECTIVE

The goal of our research was to estimate the spatial density of app users across Metro Vancouver and identify the independent and adjusted neighborhood-level factors that predict app user density.

METHODS

This pilot study used a popular geosocial networking app to estimate the spatial density of app users across rural and urban Metro Vancouver. Multiple Poisson regression models were then constructed to model the relationship between app user density and areal population-weighted neighbourhood-level factors from the 2016 Canadian Census and National Household Survey.

RESULTS

A total of 2021 app user profiles were counted within 1 mile of 263 sampling locations. In a multivariate model controlling for time of day, app user density was associated with several dissemination area-level characteristics, including population density (per 100; incidence rate ratio [IRR] 1.03, 95% CI 1.02-1.04), average household size (IRR 0.26, 95% CI 0.11-0.62), average age of males (IRR 0.93, 95% CI 0.88-0.98), median income of males (IRR 0.96, 95% CI 0.92-0.99), proportion of males who were not married (IRR 1.08, 95% CI 1.02-1.13), proportion of males with a postsecondary education (IRR 1.06, 95% CI 1.03-1.10), proportion of males who are immigrants (IRR 1.04, 95% CI 1.004-1.07), and proportion of males living below the low-income cutoff level (IRR 0.93, 95% CI 0.89-0.98).

CONCLUSIONS

This pilot study demonstrates how the combination of geosocial networking apps and administrative datasets might help care providers, planners, and community leaders target online and offline interventions for gbMSM who use apps.

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

OBJECTIVES

Pre-exposure prophylaxis (PrEP) is a highly effective, HIV prevention strategy increasingly being accessed by gay, bisexual, and other men who have sex with men (GBMSM). GBMSM face structural and individual-level barriers accessing PrEP, including awareness and cost. This paper assesses socio-demographic factors associated with awareness, interest, and willingness to pay for PrEP in a sample of Canadian GBMSM.

METHODS

Data were derived from the 2015 Sex Now survey, a cross-sectional, online survey of GBMSM. Respondents were recruited through social media, sex-seeking "apps," and by word of mouth. We used univariable and multivariable logistic regression models to estimate associations between socio-demographic factors and three primary outcomes.

RESULTS

Our sample consisted of 7176 HIV-negative Canadian GBMSM. Of respondents, 54.7% were aware of PrEP, 47.4% were interested in PrEP, and 27.9% of PrEP-interested respondents reported they would pay for PrEP out-of-pocket. Awareness and interest varied between provinces, while GBMSM outside urban areas were less likely to be PrEP aware. Bisexual-identified men, and men over 50, were less likely to be aware and interested in PrEP in multivariable models. Only annual income and educational attainment were associated with willingness to pay for PrEP.

CONCLUSION

This study identifies important disparities in awareness, interest, and willingness to pay for PrEP. Future interventions and educational efforts should target non-gay-identified and older GBMSM, as well as GBMSM outside urban areas. PrEP implementation may risk further perpetuating existing health inequities based on socio-economic status if PrEP continues to be accessed primarily through private insurance or paid for out-of-pocket.

Prevalence of Depression and Anxiety Among Bisexual People Compared to Gay, Lesbian, and Heterosexual Individuals:A Systematic Review and Meta-Analysis

Over the past decade, evidence has accumulated to suggest that bisexual people experience higher rates of poor mental health outcomes compared to both heterosexual and gay/lesbian individuals. However, no previous meta-analyses have been conducted to establish the magnitude of these disparities. To address this research gap, we conducted a systematic review and meta-analysis of studies that reported bisexual-specific data on standardized measures of depression or anxiety. Of the 1,074 full-text articles reviewed, 1,023 were ineligible, predominantly because they did not report separate data for bisexual people (n = 562 studies). Ultimately, 52 eligible studies could be pooled in the analysis. Results indicate that across both outcomes, there is a consistent pattern of lowest rates of depression and anxiety among heterosexual people, while bisexual people exhibit higher or equivalent rates in comparison to lesbian/gay people. On the basis of empirical and theoretical literature, we propose three interrelated contributors to these disparities: experiences of sexual orientation-based discrimination, bisexual invisibility/erasure, and lack of bisexual-affirmative support. Implications for interventions to improve the health and well-being of bisexual people are proposed.

Evidence of Multiple Mediating Pathways in Associations Between Constructs of Stigma and Self-Reported Suicide Attempts in a Cross-Sectional Study of Gay and Bisexual Men

Gay and bisexual men (GBM) are more likely to attempt suicide than heterosexual men. This disparity is commonly interpreted using minority stress theory; however, specific pathways from antigay stigma to suicidal behavior are poorly understood. We aimed to estimate associations between multiple constructs of stigma and suicide attempts among adult GBM, and to measure the proportion of these associations mediated by distinct suicide risk factors, thus identifying proximal points of intervention. Data were drawn from a Canadian community-based survey of adult GBM. Structural equation modeling was used to compare associations between three latent constructs-enacted stigma (e.g., discrimination, harassment), anticipated prejudice (worry about encountering antigay/bisexual prejudice), and sexuality concealment-and self-reported suicide attempts (last 12 months). Coefficients were estimated for direct, indirect, and total pathways and evaluated based on magnitude and statistical significance. The proportion of associations mediated by depression, drug/alcohol use, and social isolation was calculated using indirect paths. Among 7872 respondents, 3.4% reported a suicide attempt in the past 12 months. The largest total association was observed for enacted stigma, and this association was partially mediated by depression and drug/alcohol use. The total association of anticipated prejudice was relatively smaller and mediated by depression and social isolation. Concealment had an inverse association with suicide attempts as mediated by depression but was also positively associated with suicide attempts when mediated through social isolation. Multiple constructs of antigay stigma were associated with suicide attempts; however, mediating pathways differed by construct, suggesting that a combination of strategies is required to prevent suicide in adult GBM.

Online interventions to address HIV and other sexually transmitted and blood-borne infections among young gay, bisexual and other men who have sex with men: a systematic review

Introduction

Globally, young gay, bisexual and other men who have sex with men (gbMSM) continue to experience disproportionately high rates of HIV and other sexually transmitted and blood‐borne infections (STBBIs). As such, there are strong public health imperatives to evaluate innovative prevention, treatment and care interventions, including online interventions. This study reviewed and assessed the status of published research (e.g. effectiveness; acceptability; differential effects across subgroups) involving online interventions that address HIV/STBBIs among young gbMSM.

Methods

We searched Medline, Embase, PsycINFO, CINAHL, and Google Scholar to identify relevant English‐language publications from inception to November 2016. Studies that assessed an online intervention regarding the prevention, care, or treatment of HIV/STBBIs were included. Studies with <50% gbMSM or with a mean age ≥30 years were excluded.

Results

Of the 3465 articles screened, 17 studies met inclusion criteria. Sixteen studies assessed interventions at the “proof‐of‐concept” phase, while one study assessed an intervention in the dissemination phase. All of the studies focused on behavioural or knowledge outcomes at the individual level (e.g. condom use, testing behaviour), and all but one reported a statistically significant effect on ≥1 primary outcomes. Twelve studies described theory‐based interventions. Twelve were conducted in the United States, with study samples focusing mainly on White, African‐American and/or Latino populations; the remaining were conducted in Hong Kong, Peru, China, and Thailand. Thirteen studies included gay and bisexual men; four studies did not assess sexual identity. Two studies reported including both HIV+ and HIV− participants, and all but one study included one or more measure of socio‐economic status. Few studies reported on the differential intervention effects by socio‐economic status, sexual identity, race or serostatus.

Conclusion

While online interventions show promise at addressing HIV/STBBI among young gbMSM, to date, little emphasis has been placed on assessing: (i) potential differential effects of interventions across subgroups of young gbMSM; (ii) effectiveness studies of interventions in the dissemination phase; and (iii) on some “key” populations of young gbMSM (e.g. those who are: transgender, from low‐income settings and/or HIV positive). Future research that unpacks the potentially distinctive experiences of particular subgroups with “real world” interventions is needed.

Differences in experiences of barriers to STI testing between clients of the internet-based diagnostic testing service GetCheckedOnline.com and an STI clinic in Vancouver, Canada

OBJECTIVES

Internet-based STI testing programmes may overcome barriers posed by in-clinic testing, though uptake could reflect social gradients. The role these services play in comparison to clinical testing services is unknown. We compared experiences of testing barriers between STI clinic clients to clients of GetCheckedOnline.com (GCO; where clients take a printed lab form to a lab).

METHODS

Our 10-month cross-sectional study was conducted after GCO was promoted to STI clinic clients and men who have sex with men (MSM). Clinic and GCO clients completed an online survey assessing testing barriers and facilitators; responses were compared using bivariate analysis (level of significance P<0.01; significant results below).

RESULTS

Compared with 321 clinic clients, the 73 GCO clients were more likely to be older (median 35 vs 30 years), MSM (45% vs 16%), be testing routinely (67% vs 39%), have delayed testing for any reason (76% vs 54%) and due to clinic distance (28% vs 9%), report delays due to wait times (50% vs 17%), embarrassment with testing (16% vs 6%), discomfort discussing sexual health where they usually go for testing (39% vs 22%), as well as discomfort discussing sexual history with (19% vs 5%) and fearing judgement from (30% vs 15%) any healthcare provider. GCO clients were less likely to have found clinic hours convenient (59% vs 77%) and clinic appointments easy to make (49% vs 66%), and more likely to report long wait times (50% vs 17%). We found no differences in technology skills/use.

CONCLUSIONS

In this urban setting, an internet-based testing service effectively engaged individuals experiencing testing barriers, with few social gradients in uptake. While some testing barriers could be addressed through increasing access to clinical services, others require social and structural changes, highlighting the importance of internet-based STI testing services to increasing test uptake.

Recent Suicide Attempts Across Multiple Social Identities Among Gay and Bisexual Men: An Intersectionality Analysis

This study draws from intersectionality to describe variations in recent suicide attempts (RSA) among gay and bisexual men (GBM) across sociodemographics. Using survey data, logistic regression modeling explored RSA in two analytical stages: (1) the individual effects of each sociodemographic were measured; (2) two-way interaction terms between sociodemographics were tested and added to the models created in stage A. In stage A, only education and income achieved significance. In stage B, the study found that (a) education and income interacted significantly such that the odds of RSA increased for those with a lower income and a lower education; (b) sexual orientation and partnership status interacted, resulting in decreased odds among bisexual men in heterosexual partnerships; and (c) income and education interacted with geography; the effects of these variables were significant only among urban men. These findings suggest that GBM are at unequal risk of RSA according to intersecting sociodemographics.

Use of GetCheckedOnline, a Comprehensive Web-based Testing Service for Sexually Transmitted and Blood-Borne Infections

Background

The British Columbia Centre for Disease Control implemented a comprehensive Web-based testing service GetCheckedOnline (GCO) in September 2014 in Vancouver, Canada. GCO’s objectives are to increase testing for sexually transmitted and blood-borne infections (STBBIs), reach high-prevalence populations facing testing barriers, and increase clinical STI service capacity. GCO was promoted through email invitations to provincial STI clinic clients, access codes to clients unable to access immediate clinic-based testing (deferred testers), and a campaign to gay, bisexual, and other men who have sex with men (MSM).

Objective

The objective of the study was to report on characteristics of GCO users, use and test outcomes (overall and by promotional strategy) during this pilot phase.

Methods

We used GCO program data, website metrics, and provincial STI clinic records to describe temporal trends, progression through the service pathway, and demographic, risk, and testing outcomes for individuals creating GCO accounts during the first 15 months of implementation.

Results

Of 868 clients creating accounts, 318 (36.6%) submitted specimens, of whom 96 (30.2%) tested more than once and 10 (3.1%) had a positive STI diagnosis. The proportion of clients submitting specimens increased steadily over the course of the pilot phase following introduction of deferred tester codes. Clients were diverse with respect to age, gender, and ethnicity, although youth and individuals of nonwhite ethnicity were underrepresented. Of the 506 clients completing risk assessments, 215 (42.5%) were MSM, 89 (17.6%) were symptomatic, 47 (9.3%) were STI contacts, 232 (45.8%) reported condomless sex, 146 (28.9%) reported ≥4 partners in the past 3 months, and 76 (15.0%) reported a recent STI. A total of 63 (12.5%) GCO clients were testing for the first time. For 868 accounts created, 337 (38.8%) were by clinic invitations (0 diagnoses), 298 (34.3%) were by deferred testers (6 diagnoses), 194 (22.4%) were by promotional campaign (3 diagnoses), and 39 (4.5%) were by other means (1 diagnosis).

Conclusions

Our evaluation suggests that GCO is an acceptable and feasible approach to engage individuals in testing. Use by first-time testers, repeated use, and STI diagnosis of individuals unable to access immediate clinic-based testing suggest GCO may facilitate uptake of STBBI testing and earlier diagnosis. Use by MSM and individuals reporting sexual risk suggests GCO may reach populations with a higher risk of STI. Motivation to test (eg, unable to access clinical services immediately) appears a key factor underlying GCO use. These findings identify areas for refinement of the testing model, further promotion, and future research (including understanding reasons for drop-off through the service pathway and more comprehensive evaluation of effectiveness). Increased uptake and diagnosis corresponding with expansion of the service within British Columbia will permit future evaluation of this service across varying populations and settings.

Stigma and suicide among gay and bisexual men living with HIV

HIV positive gay and bisexual men (GBM) continue to struggle with the pervasiveness of HIV stigma, but little is known about the health effects of stigma. In this article, suicidal ideation and attempts are measured among GBM living with HIV, evaluating the extent to which these experiences are associated with stigma and suicide. Drawing from an online national survey of Canadian GBM completed by 7995 respondents, a sub-set of data provided by respondents self-reporting HIV-positive status was used for the current study. The associations between suicidal ideation (SI) and attempts (SA) and four measures of HIV stigma were measured: social exclusion, sexual rejection, verbal abuse and physical abuse. A total of 673 HIV-positive men completed the survey (8% of total sample). Among this group, 22% (n = 150) reported SI and 5% (n = 33) SA in the last 12 months. After adjusting for sociodemographic factors, SI and SA were associated with each of the four measures of HIV stigma: being excluded socially for being HIV positive (SI adjusted odds ratio, AOR 2.0 95% CI 1.4-3.1; SA AOR 3.8 95% CI 1.9-7.9), rejected as a sexual partner (SI AOR 1.6 95% CI 1.1-2.4; SA AOR 2.6 95% CI 1.1-6.0), verbally abused (SI AOR 2.9 95% CI 1.9-4.5; SA AOR 2.4 95% CI 1.1-5.1), and physically abused (SI AOR 4.5 95% CI 1.8-11.7; SA AOR 6.4 95% CI 2.0-20.1). Furthermore, experiencing multiple forms of stigma was associated with significantly increased risk of SI and SA. The authors conclude that HIV positive GBM experience significant levels of stigma that are associated with heightened risk for suicide. The findings affirm the need for targeted interventions to prevent suicide amid public health efforts to de-stigmatize HIV and mental illness.
