Background: Social geography plays an important role in transmission of sexually transmitted infections (STIs) among men who have sex with men. Previous qualitative work had identified 7 "geosexual archetypes," each with distinct travel patterns for sex and potentially important differences in STI rates. The objective of this article was to explore what could be learned about STI transmission by looking at STI prevention strategies (condom use and preexposure prophylaxis use) and prevalence of STIs among these geosexual archetypes., Methods: We analyzed data from the Sex Now 2019 online survey in Canada. Men who have sex with men who reported 3 or more partners in the past 6 months were included in the analysis (n = 3649)., Results: The most common archetype was "geoflexible" (sex at home, partner's home, and other places; 35.6%), followed by "privates" (sex only at own/partner's home; 23.0%); the least common archetypes was "rover" (sex not at home or partner's place; 4.0%). There were significant variations in both STI prevention strategies and prevalence of bacterial STIs in the past year by geosexual archetype. In particular, among those who were HIV negative, those who reported a geoflexible archetype and used preexposure prophylaxis but did not use condoms consistently had a 52.6% prevalence of bacterial STIs, which was much higher compared with all other groups. Within other archetypes, those living with HIV had the highest prevalence of bacterial STIs., Conclusions: Geosexual archetype together with participant's STI prevention strategies was a strong predictor of bacterial STI risk. Understanding how place is connected to bacterial STIs is key in prevention as individuals do not live in isolation., Competing Interests: Conflict of Interest and Sources of Funding: The authors have no conflict of interest to declare.

Objectives: As the primary public health strategy for controlling the 2022 Mpox outbreak, it is critical to evaluate the impact of Mpox vaccination campaigns for transgender people and gay, bisexual and other men who have sex with men (T/GBM). We measured vaccine uptake and associated factors among T/GBM clients of an urban STI clinic in British Columbia (BC)., Methods: We conducted a cross-sectional online survey between August 8-22, 2022 of clients who had attended the STI clinic, 5-7 weeks following the first-dose Mpox vaccination campaign in BC. We drew on a systematic review of factors associated with vaccine uptake to develop survey questions, and measured vaccine uptake among vaccine-eligible T/GBM., Results: Overall, 51% of T/GBM had received the first dose of the vaccine. The sample (331 participants) was majority White and university educated, identified as a man and gay, 10% had trans experience, and 68% met eligibility criteria for vaccination. Among vaccine-eligible participants identifying as T/GBM, 66% had been vaccinated; being unvaccinated was more common among participants identifying as bisexual or heteroflexible/mostly straight, and who spent less time with other T/GBM. Eligible yet unvaccinated participants had lower perceived susceptibility, and reported fewer cues to action (e.g., fewer saw information promoting the vaccine), and increased constraints to vaccine access; vaccine barriers related to accessing clinics and privacy were common. The majority (85%) of those eligible and unvaccinated at time of survey were willing to receive the vaccine., Conclusion: In this sample of STI clinic clients, vaccine uptake among eligible T/GBM was high in the initial weeks following a Mpox vaccination campaign. However, uptake was patterned on social gradients with lower uptake among T/GBM who may be less effectively engaged by available promotion channels. We recommend early, intentional and diverse engagement of T/GBM populations in Mpox and other targeted vaccination programs., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Objectives: We assessed COVID-19 pandemic impacts on accessing needed sexual health services, and acceptability of alternative service delivery models, among sexual health service clients in British Columbia (BC), Canada., Methods: We administered an online survey on 21 July-4 August 2020 to clients using a provincial STI clinic or internet-based testing service, GetCheckedOnline, in the year prior to March 2020. We used logistic regression to identify factors associated with having unmet sexual health needs (ie, not accessing needed services) during March-July 2020 and the likelihood of using various alternative service models, if available., Results: Of 1198 survey respondents, 706 (59%) reported needing any sexual health service since March 2020; of these 706, 365 (52%) did not access needed services and 458 (66%) had avoided or delayed accessing services. GetCheckedOnline users (univariate OR (uOR)=0.62; 95% CI 0.43 to 0.88) or clients with more urgent needs (eg, treatment for new STI, uOR 0.40 (95% CI 0.21 to 0.7)) had lower odds of unmet sexual health needs. The most common factors reported for avoiding or delaying access were public messaging against seeking non-urgent healthcare (234/662, 35%), concern about getting COVID-19 while at (214/662, 32%) or travelling to (147/662, 22%) a clinic or lab and closure of usual place of accessing services (178/662, 27%). All factors were positively associated with having unmet sexual health needs, with public messaging showing the strongest effect (adjusted OR=4.27 (95% CI 2.88 to 6.42)). Likelihood of using alternative sexual health service models was high overall, with the most appealing options being home self-collection kits (634/706, 90%), receiving test kits or antibiotics at home (592/700, 85%) and express testing (565/706, 80%)., Conclusions: Of BC sexual health service clients needing services during March-July 2020, many had unmet needs. Offering alternative service delivery methods may help to improve access during and beyond the COVID-19 pandemic., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

A wide variety of risk calculators estimate individuals' risk for HIV/sexually transmitted infections (STI) online. These tools can help target HIV/STI screening and optimize clinical decision-making. Yet, little evidence exists on suitable features for these tools to be acceptable to end-users. We investigated the desirable characteristics of risk calculators among STI clinic clients and testing service providers. Participants interacted with online HIV/STI risk calculators featuring varied target audiences, completion lengths, and message outputs. Thematic analysis of focus groups identified six qualities that would make risk calculators more appealing for online client use: providing personalized risk assessments based on users' specific sexual behaviors and HIV/STI-related concerns; incorporating nuanced risk assessment and tailored educational information; supplying quantifiable risk estimates; using non-stigmatizing and inclusive framing; including explanations and next steps; and developing effective and appropriate branding. Incorporating these features in the design of online HIV/STI risk calculators may improve their acceptability among end-users.

Background: Our objective was to explore the sexual health knowledge, attitudes, and perceptions of men who have sex with men (MSM)., Methods: In-depth interviews were conducted with 31 MSM who lived, worked, or socialized in Toronto in June and July 2016. Participants were asked about concepts of risky sex and knowledge of, and attitudes toward, sexually transmitted infections (STIs), especially syphilis, and potential interventions. Thematic analysis was used to analyze interview transcripts., Results: The prevention of STI relied on HIV prevention strategies. No one used condoms for oral sex, nor did they intend to. Pre-exposure prophylaxis was perceived as both threatening and liberating. Concepts of risky sex included emotional risk. Conversations with partners about STI testing were easier than STI status. Stigma and concealment of sexual identity were barriers to sexual health care. None of the participants recommended sexual behavior or sexual health interventions. Instead, recommendations centered on social changes to reduce or eliminate shame, embarrassment, stigma, and discrimination around both STIs and sexual orientation., Conclusion: Participants were thinking about sexual risk and using a variety of ways to prevent STI transmission, although most relied on HIV prevention strategies, possibly because they knew little about other STIs, and other STIs were perceived as curable, especially syphilis. Interventions promoting conversations about STI testing may be promising and will also reduce stigma as STI testing is normalized. Social and clinic interventions focused on creating psychologically safe spaces to disclose sexual identity and providing sexual orientation affirming health care may reduce STIs and improve sexual health for MSM.

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., Competing Interests: Competing interests: TS, DH, MK, JS, GO, and MG report the above-named grants from Canadian Institutes of Health Research, during the conduct of the study., (© Author(s) (or their employer(s)) 2019.

Context: Sexually transmitted infections (STI) and mental health and substance use (MHSU) disorders all occur at elevated rates in sexual and gender minorities. These overlapping epidemics, or syndemics, are exacerbated by challenges these same populations face in accessing sexual/gender minority-affirming services. Many publicly funded STI clinics are a low barrier and provide sexual minority-competent care. These sites therefore may be uniquely situated to address clients' MHSU-related needs., Objective: We characterize the need and desire for MHSU services among STI clinic clients., Design, Setting, Participants: We conducted a waiting room survey at 6 STI clinics in Metro Vancouver, Canada., Main Outcome Measures: We calculated the proportion of clients with self-reported unmet MHSU needs in the previous 12 months and, among these clients, barriers to accessing MHSU services and desire for MHSU services within the STI clinic. We also examined social disparities in barriers to accessing MHSU services., Results: Among 1115 respondents-65% of whom were sexual minorities-39% reported a recent need for MHSU-related care, most frequently in relation to anxiety (29%), depression (26%), substance use (10%), or suicide ideation (7%). Seventy-two percent of this group had not yet talked to a provider about their concern. Common barriers included shame (26%) and inability to afford the service (24%). Eighty-three percent of clients with unmet MHSU needs indicated that they were comfortable discussing MHSU concerns with an STI clinic provider, and 94% expressed desire to receive MHSU assessments, referrals, or counseling in the STI clinic. Sexual and gender minorities and those attending a suburban clinic were more likely to report barriers to accessing MHSU services., Conclusions: More than a quarter of STI clinic clients report unmet MHSU health care needs; moreover, these clients report high levels of comfort with and desire to discuss MHSU concerns with STI clinic providers. Sexually transmitted infections clinics are thus opportune sites for syndemic service integration.

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., Competing Interests: Competing interests: MK has received contract or grant funding to his institution from Roche, Merck, Hologic, Boehringer Ingelheim, and Siemens that was unrelated to this work., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2019.

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., (© 2017 The Authors.

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., (©Mark Gilbert, Travis Salway, Devon Haag, Christopher K Fairley, Jason Wong, Troy Grennan, Zhaida Uddin, Christopher S Buchner, Tom Wong, Mel Krajden, Mark Tyndall, Jean Shoveller, Gina Ogilvie.
