Assessing understandings and perceptions of HIV cure among peer navigators and treatment officers in Australia.

HIV community peer navigators and treatment officers are important sources of information and guidance for people living with HIV. We conducted an anonymous online survey with members of the treatment outreach network of the Australian National Association of People Living with HIV. The survey explored understandings and acceptance of HIV cure research and was disseminated before and following an interactive workshop on HIV cure. We demonstrated an improvement in understandings of HIV cure science and increased willingness to participate in interventional clinical trials after the workshop. Concerns around interrupting HIV treatment and detrimental impacts on health were identified as barriers to participation. Altruism was a motivator to enrol in HIV cure trials, along with endorsement from a trusted member of community.

Corrigendum to: Familiarity with, perceived accuracy of, and willingness to rely on Undetectable=Untransmittable (U=U) among gay and bisexual men in Australia: results of a national cross-sectional survey.

BACKGROUND: The Undetectable=Untransmittable (U=U) message has been promoted since it was demonstrated that viral suppression through HIV treatment prevents sexual transmission between serodiscordant partners (HIV treatment as prevention). Our study assessed familiarity with, perceived accuracy of, and willingness to rely on U=U in a national sample of gay and bisexual men in Australia. METHODS: We conducted a national, online cross-sectional survey in April-June 2021. Eligible participants were gay, bisexual and queer men and non-binary people who lived in Australia. Logistic regression was used to identify factors associated with familiarity, perceived accuracy and willingness to rely on U=U (by having condomless sex with a partner with HIV who has an undetectable viral load). RESULTS: Of 1280 participants, most were familiar with U=U (1006/1280; 78.6%), the majority of whom believed U=U was accurate (677/1006; 67.3%). Both familiarity and perceived accuracy were higher among participants living with HIV, followed by pre-exposure prophylaxis (PrEP) users, HIV-negative participants not taking PrEP, and untested/unknown status participants. Knowing at least one person living with HIV, among other factors, was associated with familiarity and perceived accuracy of U=U; and familiarity was associated with perceived accuracy. Among participants familiar with U=U, less than half were willing to rely on U=U (473/1006; 47.0%). Familiarity with U=U and knowing at least one person living with HIV were associated with willingness to rely on U=U, among other factors. CONCLUSIONS: We found familiarity with U=U was associated with perceived accuracy and willingness to rely upon it. There is an ongoing need to educate gay and bisexual men (particularly HIV-negative men) about U=U and its benefits.

'It's like I have this weird superpower': experiences of detectable and undetectable viral load among a cohort of recently diagnosed people living with HIV.

BACKGROUND: By reducing HIV viral load to undetectable levels, HIV treatment slows disease progression and eliminates the possibility of sexual transmission. The promotion of undetectable viral load has also been accompanied by expectations of reducing HIV-related stigma, including self-stigma. Drawing on accounts of people recently diagnosed with HIV, we explored experiences of both detectable and undetectable viral load. METHODS: Between January 2019 and November 2021, semi-structured interviews were conducted with 35 people living with HIV (PLHIV) who had received an HIV diagnosis in Australia from 2016 onward. Of these participants, 24 completed follow-up interviews approximately 12months later. Interviews were transcribed verbatim, entered into NVivo (software v12), and thematically analysed. RESULTS: Reflecting on the period in which their viral load was detectable, some participants described feeling 'dirty,' 'viral,' and 'a risk' to sexual partners. During this period, some participants minimised or ceased having sex, sometimes despite being in ongoing romantic relationships. Reaching undetectable viral load was commonly characterised as an important goal in HIV care and signalled a marker of good health and enabled a return to sexual relationships. However, the psychosocial benefits of undetectable viral load were not universally experienced, with some participants highlighting ongoing challenges of living with HIV long term. CONCLUSIONS: Increasing awareness of the benefits of undetectable viral load is an important and powerful tool for improving the health and wellbeing of PLHIV; however, the period in which one's HIV viral load is detectable can be challenging, particularly as feelings of being 'unclean' and 'a risk' may be internalised. Ensuring PLHIV are appropriately supported during periods of viral detectability is necessary.

Requesting HIV Results Be Conveyed in-Person: Perspectives of Clinicians and People Recently Diagnosed with HIV.

Introduction: Guidelines recommend that, where possible, clinicians convey HIV-positive test results in person in Australia. However, HIV-negative and all other STI results are routinely delivered by phone or text message. Requesting individuals to obtain positive HIV test results in person could be a deviation from the standard delivery of healthcare and be interpreted as indicating a positive HIV diagnosis. Methods: This paper is based on two related, ongoing qualitative studies conducted in Australia with HIV healthcare providers and people recently diagnosed with HIV. In study one, in-depth, semi-structured interviews were conducted with people who had recently received a positive HIV diagnosis. In study two, in-depth, semi-structured interviews were conducted with HIV healthcare and peer support providers. Interviews were analyzed thematically. Results: While clinicians were willing to convey HIV-positive diagnoses by phone, most preferred in-person delivery. In-person delivery enabled clinicians to assess visual cues to better respond to the psychological and emotional needs of patients. For some participants living with HIV, however, the requirement to return to the clinic was interpreted as an unofficial HIV-positive diagnosis. This led to a period in which recently diagnosed participants believed they were HIV-positive without having received an explicit diagnosis. Conclusion: Protocols for delivering HIV diagnoses by phone, followed by a face-to-face appointment, may reduce the period of anxiety for some patients and assist with an early connection to HIV care and support. Policy Implications: In some instances, conveying HIV diagnoses by phone may be more appropriate than recalling individuals to the clinic to deliver a positive HIV diagnosis in person.

Engaging Stigmatised Communities in Australia with Digital Health Systems: Towards Data Justice in Public Health.

Introduction: In 2018, following government policy changes to Australia's national electronic health record system, 'My Health Record', consumer advocates-including organisations representing people living with HIV, people who use drugs and sex workers-raised concerns about privacy and data security. Responding to these controversies, this study explores the practical, ethical and political complexities of engaging stigmatised communities with digital health systems. Methods: We conducted 16 qualitative semi-structured interviews in 2020 with key informants representing communities who experience stigma, discrimination and marginalisation in Australia. These communities included people living with HIV, sex workers, people who inject drugs, gay and bisexual men and transgender and gender diverse people. We conducted a reflexive thematic analysis. Results: Key informants were sceptical of proposed benefits of electronic health records for their communities, and concerned about privacy risks and the potential for discrimination. Meaningful consultation, consent mechanisms and tackling structural stigma were raised as solutions for engaging communities. Conclusions: Although communities could benefit from being included in digital health systems, significant cultural, legal and social reforms from government were believed to be necessary to build trust in digital health systems. We argue that these forms of data justice are necessary for effective future systems. Policy Implications: Engaging stigmatised communities-including in relation to gender, sexuality, sex work, drug use, HIV-requires a commitment to data justice. The design and implementation of digital health systems requires investment in ongoing and meaningful consultation with communities and representative organisations.

HIV Diagnosis as Both Biographical Disruption and Biographical Reinforcement: Experiences of HIV Diagnoses Among Recently Diagnosed People Living With HIV.

Despite the potential for HIV treatments to transform the health needs of people living with HIV, receiving a positive HIV diagnosis can be a difficult experience and feelings of shock, distress and concerns for the future are commonly reported. Drawing on Michael Bury's conceptualisation of 'biographical disruption', we utilised semi-structured interviews to explore experiences of HIV diagnoses among 34 people diagnosed with HIV between 2016 and 2020 and living in Australia. Interviews were conducted between January 2018 and August 2021. Despite significant advances in biomedical HIV treatments and prevention, participants commonly experienced HIV diagnosis as emotionally challenging. For those with limited HIV awareness, HIV was commonly understood as a likely fatal condition. For some participants, receiving a positive diagnosis also engendered a degree of uncertainty as to their anticipated life trajectory, particularly its impact on future sexual and romantic relationships, options for starting a family and migration opportunities. For some gay and bisexual male participants, receiving a positive diagnosis almost confirmed a life trajectory that they had worked to avoid and their own sometimes-negative attitudes toward people living with HIV were internalised, making adjusting to diagnosis more complex. While all participants reported challenges in adjusting to an HIV diagnosis, some ultimately came to experience living with HIV as bringing about unexpected and welcome changes to their lives. Our findings highlight the complex and intersecting medical, social and emotional needs of people living with HIV when receiving and adjusting to a positive HIV diagnosis.

Experiences of, and motivations for, disclosing HIV to social and familial networks: considering the social and relational domains of HIV disclosure.

For people living with HIV, decisions about when, how and who to tell about their HIV status can involve navigating complex social, legal and health domains. With a focus on disclosure to broader social and familial networks, we explored the experiences of, and motivations for, HIV (non-)disclosure among recently diagnosed people living with HIV in Australia. Semi-structured interviews were conducted with 35 people diagnosed with HIV from 2016 onwards, of whom 25 completed follow-up interviews. Participants commonly reported anticipating negative responses and rejection from others when considering whether to disclose their HIV status. Some participants also took on the role of ensuring others' wellbeing when disclosing (or not), even as they themselves needed emotional support. Finally, some participants felt it important to be open about their HIV status to raise awareness of HIV and challenge HIV-related stigma. Our findings highlight the complex relational and social contexts that shape HIV disclosure. In addition to supporting individual people living with HIV when disclosing, we argue that educational programmes that target the broader, HIV-negative population are needed to shift the social landscape in which people living with HIV disclose.

Relationship Between Sexual Behaviors with Non-committed Relationship Partners and COVID-19 Restrictions and Notification Rates: Results from a Longitudinal Study of Gay and Bisexual Men in Australia.

Introduction: COVID-19 related lockdowns have impacted the sexual activity of gay and bisexual men (GBM). We investigated trends in sexual behaviors and the COVID-19 context in which they occurred (COVID-notification rates and jurisdictional restrictions) to understand changes in the duration and severity of periods of lockdown on the sexual behavior of Australian GBM. Methods: In an online, prospective observational study of 831 GBM from May 2020 to May 2021, we investigated associations between changes in sexual behavior among Australian GBM, lockdowns, and COVID-19 notification rates through weekly surveys from May 2020 to May 2021. Results: The mean age was 45.71 years (SD: 13.93). Most identified as gay (89.0%) and 10.2% were living with HIV. There was an overall increase in the mean weekly number of non-committed relationship partners (0.53-0.90, p < 0.001). The state of Victoria experienced a significant extended COVID-19 outbreak, accompanied by severe lockdown restrictions. In response, Victorian men's partner numbers shifted three times, while elsewhere there was an overall gradually increasing trend. Conclusions: Less severe outbreaks with shorter lockdown periods, involving fewer and geographically contained, COVID-19 notifications were accompanied by non-significant changes in sex with non-relationship partners than more severe outbreaks over extended periods and larger geographical areas.

How to have sex in a pandemic: the development of strategies to prevent COVID-19 transmission in sexual encounters among gay and bisexual men in Australia.

Although many studies reported on decreases in sexual partner numbers among gay and bisexual-identifying men in the early period of the COVID-19 pandemic, few studies have explored COVID-19 risk-reduction strategies. Drawing on free-text responses in an online survey (from April to July 2020), we describe the ways in which men sought to minimise the risk of COVID-19 in sexual encounters. Partner selection was an important strategy, in particular, restricting sex to men they already knew. Accounts also indicate how participants assessed risk from potential sex partners based on symptoms, residential location, recent travel, work role, and number of other sexual contacts. Less common were in situ practices, such as avoiding kissing. Participants' responses provide insight into creative community-based responses in the early months of the pandemic, some of which have resonances with early responses to HIV. Findings are discussed in relation to the concepts of 'lay epidemiology' and 'counterpublic health'. In particular, we examine how risks and health are experienced and valued in relation to local knowledges, meanings, and practices; and how practices emerge in response to dominant public health discourses that produce an idealised public based on (hetero)normative assumptions.

Changing Attitudes Towards Condoms Among Australian Gay and Bisexual Men in the PrEP Era: An Analysis of Repeated National Online Surveys 2011-2019.

Condoms have been the primary form of HIV prevention for gay and bisexual men (GBM) for most of the HIV epidemic. The introduction of biomedical HIV prevention may have changed attitudes towards condoms. Data from repeated national online surveys of GBM in Australia were used to examine how attitudes towards condoms and confidence discussing condoms with partners changed in the period 2011-2019. The proportion of all participants who reported a positive experience in using condoms remained low and unchanged (9.6% in 2011 to 6.0% in 2019). Confidence in discussing condoms with partners decreased over time (from 72.2% in 2011 to 56.6% in 2019). Confidence in discussing condoms was associated with concern about sexually transmitted infections, and more consistent condom use. Sustaining confidence in using condoms may be more challenging as biomedical prevention methods become more commonly used.

Belonging, social connection and non-clinical care: Experiences of HIV peer support among recently diagnosed people living with HIV in Australia.

Effective HIV treatments have transformed the medical needs of people living with HIV (PLHIV) to a chronic condition. However, stigma, poorer mental health outcomes and social isolation remain significant challenges for many PLHIV. HIV peer support programs have assisted PLHIV in navigating the clinical, emotional and social aspects of living with HIV. We draw on semi-structured interviews with 26 recently diagnosed PLHIV in Australia to explore experiences of HIV peer support services. Our thematic analysis identified three overarching themes. First, participants commonly reported that peer support programs offered a sense of belonging and connection to a broader HIV community. This established a network, sometimes separate to their existing social networks, of other PLHIV with whom to share experiences of HIV. Second, peer-based programs provided an opportunity for participants to hear firsthand, non-clinical perspectives on living with HIV. While participants valued the clinical care they received, the perspectives of peers gave participants insights into how others had managed aspects of living with HIV such as disclosure, sex and relationships. Finally, participants highlighted important considerations around ensuring referrals were made to socially and culturally appropriate support programs. Peer support programs fill an important gap in HIV care, working alongside and extending the work of the clinical management of HIV. Incorporating formal referrals to peer support services as part of the HIV diagnosis process could assist recently diagnosed PLHIV in adjusting to a positive diagnosis.

COVID-19 Vaccination Uptake and Hesitancy in a National Sample of Australian Gay and Bisexual Men.

Minority groups may face additional barriers to vaccination. In April-June 2021, we assessed the level of COVID-19 vaccination and willingness to be vaccinated in a national, online survey of 1280 gay and bisexual men in Australia. Over a quarter of the sample (28.0%) had been partially or fully vaccinated, and 80.0% of the unvaccinated were willing to be vaccinated. Vaccination was independently associated with older age, being university educated, and HIV status (with HIV-positive participants being more likely and untested participants less likely to be vaccinated). Willingness to be vaccinated was independently associated with living in a capital city and being university educated. Those who had lost income or their job due to COVID-19 were less willing to be vaccinated. Our results suggest encouraging COVID-19 vaccination among those with lower levels of health literacy and supporting those who have experienced financial stress because of the pandemic.

RESUMEN: Los grupos minoritarios pueden enfrentar barreras adicionales accediendo a una vacuna. En abril-junio de 2021, evaluamos el nivel de vacunación contra el COVID-19 y la disposición a la vacuna utilizando datos de una encuesta nacional en línea de 1280 hombres gays y bisexuales en Australia. El 28% de los participantes habían sido vacunados parcial o totalmente, y el 80% de los no vacunados estaban dispuestos a vacunarse. La vacunación se asoció de forma independiente con participantes de mayor edad, con educación universitaria y su estado de VIH (los participantes VIH positivos tenían más probabilidades que los participantes sin prueba del VIH de ser vacunados). La disposición a favor de ser vacunados se asoció de manera independiente con vivir en una ciudad capital y tener estudios universitarios. Aquellos que habían perdido ingresos o su trabajo debido al COVID-19 estaban menos dispuestos a vacunarse. Nuestros hallazgos sugieren que es importante promover la vacunación contra el COVID-19 entre personas que tienen menos información en temas de salud y apoyar a quienes han sufrido estrés financiero debido a la pandemia.

Increasing preexposure prophylaxis use and 'net prevention coverage' in behavioural surveillance of Australian gay and bisexual men.

OBJECTIVES: To assess trends in HIV prevention strategies among Australian gay and bisexual men (GBM) since the introduction of preexposure prophylaxis (PrEP), the level of net prevention coverage (the use of safe strategies), and the characteristics of HIV-negative and untested GBM who remain at risk of HIV. DESIGN: Repeated behavioural surveillance of GBM recruited from venues, events and online in seven Australian states and territories. METHODS: Participants with casual male partners were included. Trends in sexual practices, prevention strategies, net prevention coverage and the characteristics of 'at risk' participants were assessed with binary and multivariate logistic regression. RESULTS: A total of 32 048 survey responses (2014-2019) were included. The proportion of participants who reported consistent condom use declined (44.6-23.2%). The proportion who reported any condomless anal intercourse with casual partners increased (37.4-62.0%) but net prevention coverage also increased (68.1-74.9%), with higher levels of undetectable viral load among HIV-positive participants and rapidly increasing PrEP use by HIV-negative participants. PrEP became the most commonly reported prevention strategy in 2019 (31.1%). The analysis of 'at risk' participants showed that they became more likely to report frequent condomless anal intercourse with casual partners but had fewer partners and more partners with undetectable viral load or on PrEP. 'At risk' participants became more likely to identify as bisexual and to be born overseas. CONCLUSION: There has been a rapid, historic shift in HIV prevention among GBM in Australia. Net prevention coverage has increased among GBM and 'at risk' GBM have become less at risk of HIV, facilitating reductions in HIV transmission.

Trends in Belief That HIV Treatment Prevents Transmission Among Gay and Bisexual Men in Australia: Results of National Online Surveys 2013-2019.

We have tracked belief in the effectiveness of HIV treatment as prevention (TasP) among Australian gay and bisexual men (GBM) since 2013. National, online cross-sectional surveys of GBM were conducted every 2 years during 2013-2019. Trends and associations were analyzed using multivariate logistic regression. Data from 4,903 survey responses were included. Belief that HIV treatment prevents transmission increased from 2.6% in 2013 to 34.6% in 2019. Belief in the effectiveness of TasP was consistently higher among HIV-positive participants than other participants. In 2019, higher levels of belief in TasP were independently associated with university education, being HIV-positive, using pre-exposure prophylaxis, knowing more HIV-positive people, being recently diagnosed with a sexually transmitted infection (STI) and use of post-exposure prophylaxis. Belief that HIV treatment prevents transmission has increased substantially among Australian GBM, but remains concentrated among HIV-positive GBM, those who know HIV-positive people, and GBM who use antiretroviral-based prevention.

Substantial Decline in Use of HIV Preexposure Prophylaxis Following Introduction of COVID-19 Physical Distancing Restrictions in Australia: Results From a Prospective Observational Study of Gay and Bisexual Men.

BACKGROUND: In response to the novel coronavirus disease (COVID-19) pandemic, Australia introduced public health and physical distancing restrictions in late March 2020. We investigated the impact of these restrictions on HIV preexposure prophylaxis (PrEP) use among Australian gay and bisexual men (GBM). METHODS: Participants in an ongoing online cohort study previously reported PrEP use from 2014 to 2019. In April 2020, 847 HIV-negative and untested participants completed questionnaires assessing changes in PrEP use as a result of COVID-19 public health measures. Binary logistic multiple regression was used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) to compare changes in PrEP use behaviors. RESULTS: Among 847 men, mean age was 44.1 years (SD: 12.7). PrEP use rose from 4.9% in 2015 to 47.2% in 2020. Among those, 41.8% (n = 167) discontinued PrEP use during COVID-19 restrictions. Discontinuing PrEP during COVID-19 restrictions was independently associated with being less likely to have recently tested for HIV (aOR: 0.17; 95% CI: 0.09 to 0.34; P < 0.001) and less likely to report sex with casual partners (aOR: 0.28; 95% CI: 0.14 to 0.54; P < 0.001). CONCLUSIONS: By April 2020, following the introduction of COVID-19 restrictions, GBM dramatically reduced PrEP use, coinciding with a reduction in sexual activity. Longer-term impacts of COVID-19 restrictions on sexual behaviors among GBM need to be monitored because they may foreshadow fluctuations in prevention coverage and risk of HIV infection. Our findings indicate a potential need for clear, targeted information about resumption of PrEP and on-demand optimal dosing regimens in response to ongoing changes in restrictions.

Access to Subsidized Health Care Affects HIV Pre-Exposure Prophylaxis (PrEP) Uptake Among Gay and Bisexual Men in Australia: Results of National Surveys 2013-2019.

BACKGROUND: We assessed willingness to use HIV pre-exposure prophylaxis (PrEP) and current PrEP use among gay and bisexual men (GBM) in Australia. METHODS: National, online cross-sectional surveys of GBM were conducted in 2013, 2015, 2017, and 2019. Willingness to use PrEP was measured on a previously validated scale. Trends and associations with key measures were analyzed using multivariate logistic regression. RESULTS: During 2013-2019, 4908 surveys were completed. Among HIV-negative and untested men not currently using PrEP, willingness to use PrEP increased from 23.0% in 2013 to 36.5% in 2017 (P < 0.001) but then plateaued at 32% in 2019 (P = 0.13). The proportion of current PrEP users increased significantly from 2.5% in 2015 to 38.5% in 2019 (P < 0.001). In 2019, factors independently associated with being a current PrEP user (compared with non-PrEP users who were willing to use PrEP) included having subsidized health care (Medicare), knowing HIV-positive people, being recently diagnosed with an STI other than HIV, having higher numbers of recent male sexual partners, recent condomless sex with casual and regular partners, and frequent PrEP sorting. CONCLUSION: Willingness to use PrEP has plateaued as its use has rapidly increased among GBM in Australia. PrEP use is concentrated among more sexually active men with access to subsidized health care. Free or low cost access schemes may facilitate broader access among GBM who want or need PrEP but lack access to subsidized health care.

The 'normality' of living as a gay serodiscordant couple in Sydney, Australia.

Serodiscordant couples are often understood through a discourse of HIV-risk or researched in terms of the psychological stressors they face. However, due to antiretroviral treatments people living with HIV can achieve undetectable viral loads, which not only make them non-infectious to partners, but allow them to think of their lives and relationships as safe and viable. These realisations mean that serodiscordant couples often embrace an HIV 'normalisation' discourse. In this article, we argue that this discourse of HIV 'normalisation' can overlook the more nuanced complexity of issues still faced by couples today, which reveal how their experiences of 'normal' are sometimes challenged and are not necessarily 'normal'. Utilising semi-structured interviews with 21 gay men in serodiscordant relationships in Sydney, Australia, we draw on the concept of 'home' life to explore how men engage with discourses of normalisation to describe and enact their relationships. We argue that although HIV is managed well enough to be insignificant in the context of home life, experiences or anticipation of stigma in public often remind couples that they are yet to be considered 'normal' socially.

Physical Distancing Due to COVID-19 Disrupts Sexual Behaviors Among Gay and Bisexual Men in Australia: Implications for Trends in HIV and Other Sexually Transmissible Infections.

INTRODUCTION: In March 2020, Australian state and federal governments introduced physical distancing measures alongside widespread testing to combat COVID-19. These measures may decrease people's sexual contacts and thus reduce the transmission of HIV and other sexually transmissible infections (STIs). We investigated the impact of physical distancing measures due to COVID-19 on the sexual behavior of gay and bisexual men in Australia. METHODS: Between April 4, 2020, and April 29, 2020, 940 participants in an ongoing cohort study responded to questions to measure changes in sexual behaviors during the COVID-19 pandemic. Men reported the date they become concerned about COVID-19 and whether they engaged in sexual behavior with regular or casual partners or "fuckbuddies" in the 6 months before becoming concerned about COVID-19 (hereafter referred to as "before COVID-19"), and following the date, they become concerned about COVID-19 (hereafter referred to as "since COVID-19"). Before and since COVID-19 was based on individual participants' own perceived date of becoming concerned about COVID-19. RESULTS: The mean age of was 39.9 years (SD: 13.4). Most participants (88.3%) reported sex with other men during the 6 months before COVID-19. Of the 587 men (62.4%) who reported sex with casual partners before COVID-19, 93 (15.8%) continued to do so in the period since COVID-19, representing a relative reduction of 84.2%. CONCLUSION: Gay and bisexual men in Australia have dramatically reduced their sexual contacts with other men since COVID-19. These behavioral changes will likely result in short-term reductions in new HIV and STI diagnoses. If sexual health screenings are undertaken before resuming sexual activity, this could present a novel opportunity to interrupt chains of HIV and STI transmission.

HCV knowledge, disclosure practices, and risk perceptions among gay and bisexual men who do and do not engage in group sex while using drugs.

ABSTRACT Research suggests that hepatitis C virus (HCV) transmission is more likely among gay and bisexual men (GBM) who engage in sexually adventurous practices, including group sex while using drugs. The current study explored drug use, sexual practices, HCV knowledge, HCV disclosure, and beliefs about HCV transmission among GBM (n = 193) reporting group sex after/while using drugs compared to those who did not. Survey findings indicate that men who participated in group sex while using drugs were more likely to have engaged in other sexually adventurous practices, ever injected drugs, have greater knowledge of HCV, and to be living with HIV. They were also more likely to perceive themselves at risk of acquiring HCV and to know that their sexual activities put them at risk. Interestingly, they had lower expectations of HCV disclosure and were less concerned about the HCV status of their partners. The lower expectations around disclosure and concern about the HCV status of their partners reflect the challenges for GBM in managing HCV transmission where there are limited effective behavioural strategies for reducing sexual transmission, This research also highlights the need to promote HCV testing and treatment to GBM who engage in group sex while using drugs.
