Abstract
Long-acting injectable PrEP, particularly cabotegravir (CAB-LA), has the potential to enhance HIV prevention in Asia, and was the topic of a roundtable held in Singapore in June 2023. Despite proven efficacy, CAB-LA's impact in Asia is hindered by regulatory, manufacturing, and cost barriers. There is an urgent need to address these challenges to expedite CAB-LA's introduction and scale-up, including collaborative research, streamlined regulatory processes, and increased manufacturing capacity. We call for better preparedness in long-acting PrEP in research and implementation science, product licensing and accessibility, and capacity readiness for scale-up, to meet the significant demand among key populations in Asia.

Variations in HIV Prevention Coverage in Subpopulations of Australian Gay and Bisexual Men, 2017-2021: Implications for Reducing Inequities in the Combination Prevention Era. AIDS Behav 2024; 28:1469-1484.

Abstract
Using repeated behavioural surveillance data collected from gay and bisexual men (GBM) across Australia, we assessed trends in HIV prevention coverage (the level of 'safe sex' achieved in the population by the use of effective prevention methods, including condoms, pre-exposure prophylaxis [PrEP] and having an undetectable viral load). We stratified these trends by age, country of birth/recency of arrival, sexual identity, and the proportion of gay residents in the participant's suburb. Among 25,865 participants with casual male partners, HIV prevention coverage increased from 69.8% in 2017 to 75.2% in 2021, lower than the UNAIDS target of 95%. Higher levels of coverage were achieved among older GBM (≥ 45 years), non-recently-arrived migrants, and in suburbs with ≥ 10% gay residents. The lowest levels of prevention coverage (and highest levels of HIV risk) were recorded among younger GBM (< 25 years) and bisexual and other-identified participants. Younger, recently-arrived, and bisexual GBM were the most likely to use condoms, while PrEP use was concentrated among gay men, 25-44-year-olds, and in suburbs with more gay residents. The use of undetectable viral load was most common among participants aged ≥ 45 years. Our analysis shows that high HIV prevention coverage can be achieved through a mixture of condom use, PrEP use, and undetectable viral load, or by emphasising PrEP use. In the Australian context, younger, bisexual and other-identified GBM should be prioritised for enhanced access to effective HIV prevention methods. We encourage other jurisdictions to assess the level of coverage achieved by combination prevention, and variations in uptake.

Abstract
INTRODUCTION Gonorrhoea, the sexually transmissible infection caused by Neisseria gonorrhoeae, has a substantial impact on sexual and reproductive health globally with an estimated 82 million new infections each year worldwide. N. gonorrhoeae antimicrobial resistance continues to escalate, and disease control is largely reliant on effective therapy as there is no proven effective gonococcal vaccine available. However, there is increasing evidence from observational cohort studies that the serogroup B meningococcal vaccine four-component meningitis B vaccine (4CMenB) (Bexsero), licensed to prevent invasive disease caused by Neisseria meningitidis, may provide cross-protection against the closely related bacterium N. gonorrhoeae. This study will evaluate the efficacy of 4CMenB against N. gonorrhoeae infection in men (cis and trans), transwomen and non-binary people who have sex with men (hereafter referred to as GBM+). METHODS AND ANALYSIS This is a double-blind, randomised placebo-controlled trial in GBM+, either HIV-negative on pre-exposure prophylaxis against HIV or living with HIV (CD4 count >350 cells/mm3), who have had a diagnosis of gonorrhoea or infectious syphilis in the last 18 months (a key characteristic associated with a high risk of N. gonorrhoeae infection). Participants are randomised 1:1 to receive two doses of 4CMenB or placebo 3 months apart. Participants have 3-monthly visits over 24 months, which include testing for N. gonorrhoeae and other sexually transmissible infections, collection of demographics, sexual behaviour risks and antibiotic use, and collection of research samples for analysis of N. gonorrhoeae-specific systemic and mucosal immune responses. The primary outcome is the incidence of the first episode of N. gonorrhoeae infection, as determined by nucleic acid amplification tests, post month 4. Additional outcomes consider the incidence of symptomatic or asymptomatic N. gonorrhoeae infection at different anatomical sites (ie, urogenital, anorectum or oropharynx), incidence by N. gonorrhoeae genotype and antimicrobial resistance phenotype, and level and functional activity of N. gonorrhoeae-specific antibodies. ETHICS AND DISSEMINATION Ethical approval was obtained from the St Vincent's Hospital Human Research Ethics Committee, St Vincent's Hospital Sydney, NSW, Australia (ref: 2020/ETH01084). Results will be disseminated in peer-reviewed journals and via presentation at national and international conferences. TRIAL REGISTRATION NUMBER NCT04415424.

Abstract
Evaluating HIV preexposure prophylaxis (PrEP) use and HIV risk events concurrently remains challenging. We developed a single question method for measuring prevention-effective adherence with PrEP in self-report questionnaires. In a questionnaire completed by 409 gay and bisexual men, 46% reported condomless anal sex that was not covered by their own PrEP use, and this was more common among younger, lower-income participants. Refining this questionnaire item could improve measurement of prevention-effective adherence.

Abstract
INTRODUCTION Investigating drug trends among Australian gay and bisexual men (GBM) is crucial for understanding levels of use and the potential for harm, including HIV transmission risk. METHOD Using repeated, national, cross-sectional survey data collected between 2012 and 2021 (69,567 surveys), trends of recent (previous 6 months) and frequent (weekly) drug use were analysed, using logistic regression models. The last round of data from each jurisdiction (6709 surveys) was used to compare GBM who reported no use, infrequent (less than weekly) use and frequent (at least weekly) use of party drugs to investigate the association between party drug use and HIV transmission risk, using multinomial logistic regression models. RESULTS There was a significant upward trend in any recent drug use (from 58.4% in 2012 to 64.1% in 2021; p < 0.001). Frequent party drug use remained a minority practice over the period (consistently less than 3%). In cross-sectional analysis, frequent party drug users were more likely to report behaviours with HIV transmission risks, such as condomless anal intercourse without biomedical prevention strategies (30.0% vs. 13.1%; adjusted relative risk ratio [aRRR], 2.08; 95% CI, 1.24-3.47), weekly group sex (16.3% vs. 0.6%; aRRR, 12.36; 95% CI, 5.75-26.56) and more than 20 recent sexual partners (42.5% vs. 5.0%; aRRR, 21.44; 95% CI, 5.82-78.89), compared with GBM who did not use party drugs. DISCUSSION AND CONCLUSION Our findings suggest that the frequent use of party drugs remains a marker of HIV transmission risk among Australian GBM, despite the increased adoption of biomedical HIV prevention strategies over the past few years.

Abstract
INTRODUCTION Overseas-born gay and bisexual men (GBM) are overrepresented in HIV diagnoses in Australia. We assessed social and sexual behaviours, and the use of HIV prevention and testing, by region of birth and length of residence in Australia. We sought to identify similarities and differences between recently arrived and non-recently arrived GBM from non-English-speaking countries to improve targeting and engagement with HIV testing and prevention. METHODS Data were collected in national repeated, behavioural surveillance surveys conducted across Australia during 2019-2021. Logistic regression was used to identify factors that differentiated between recently arrived (<2 years) and non-recently arrived (≥2 years in Australia) GBM from non-English-speaking countries. RESULTS Among 24,707 participants in 2019-21, 2811 (11.4%) were from high-income English-speaking countries, 714 (2.9%) were recently arrived overseas-born GBM and 3833 (15.5%) were non-recently arrived migrants. Recently arrived GBM were most likely to be born in Asia (36.1%) and Europe (21.1%). Compared with non-recently arrived GBM, recently arrived GBM from non-English-speaking countries were younger (aOR = 0.95, 95% CI = 0.94-0.96, p<0.001), more likely to be students (aOR = 1.43, 95% CI = 1.11-1.85, p = 0.005), less likely to be in full-time employment (aOR = 0.56, 95% CI = 0.46-0.69, p <0.001), more likely to report consistent condom use (aOR = 1.30, 95% CI = 1.01-1.66, p = 0.039), but had lower awareness (aOR = 0.62, 95% CI = 0.48-0.80, p<0.001) and use of pre-exposure prophylaxis (PrEP) (22.8%, vs. 32.3%, χ2 (1, 4185) = 23.78, p<0.001), and similar levels of casual sex with a risk of HIV acquisition or transmission (aOR = 1.29, 95% CI = 0.98-1.69, p = 0.066). Recently arrived GBM reported similar levels of lifetime HIV testing (aOR = 0.97, 95% CI = 0.54-1.74, p = 0.915) and recent HIV testing (OR = 1.03, 95% CI = 0.86-1.22, p = 0.779), but were much less likely to have tested at general practitioners (aOR = 0.53, 95% CI = 0.41-0.68, p<0.001) and more likely to report testing at hospitals (aOR = 3.35, 95% CI = 2.53-4.43, p<0.001), at home (aOR = 2.85, 95% CI = 1.63-4.99, p<0.001), or community-based services (aOR = 1.36, 95% CI = 1.01-1.84, p = 0.043). CONCLUSIONS Recently arrived GBM from non-English-speaking countries reported similar levels of risk of HIV acquisition to longer-term residents in Australia, but lower levels of PrEP awareness and use, and more reliance on HIV testing services which are free or low cost. It is necessary to enhance access to HIV testing and prevention among recently arrived GBM in Australia.

Abstract
BACKGROUND Female sex workers (FSWs) contribute disproportionately to HIV transmission in Uganda, and pre-exposure prophylaxis (PrEP) is effective in preventing HIV among cisgender women. Psychological factors are important for PrEP uptake, but few studies have examined psychosocial changes due to PrEP use in Uganda. METHODS In 2021, we recruited 524 FSWs in three Trans-African Highway towns and four fishing communities in south-western Uganda. We conducted structured interviews among women who were attending routine PrEP follow-up visits in six health units. Bivariable and multivariable modified regression using a robust covariance matrix estimator were used to identify factors associated with experiencing increased sexual pleasure and less worry about HIV because of PrEP. RESULTS Overall, 80.9% participants reported that sex was more pleasurable because of taking PrEP. There were statistical trends for sex being more pleasurable when taking PrEP or when having condomless sex with casual paying partners (aPR=1.19, 95% CI=1.07-1.32, P =0.001). Almost three-quarters of the participants (76.3%) were less worried about getting HIV because of PrEP. Condomless sex with casual paying partners (aPR=1.17, 95% CI=1.05-1.31, P =0.032, P =0.003) and being On PrEP for the past 1-2years (aPR=1.18, 95% CI=1.00-1.38, P =0.032) was significantly associated with HIV-related worry (aPR=1.17, 95% CI=1.05-1.31, P =0.032, P =0.003) Conclusions : We found a positive impact of PrEP in Ugandan FSWs on two key psychosocial dimensions: (1) more pleasurable sex; and (2) less worry about acquiring HIV. Interventions aiming to increase PrEP uptake may find it useful to focus on psychosocial dimensions.

Abstract
BACKGROUND Gay, bisexual, and other men who have sex with men (GBM) are overrepresented in diagnoses of sexually transmitted infections (STIs) relative to their population size. This study assessed trends in STI testing and diagnoses among GBM in Australia. METHODS The Gay Community Periodic Surveys are repeated cross-sectional behavioral surveillance surveys of GBM. Participants reported the number of anal swabs, throat swabs, urine samples, and blood tests for syphilis they undertook in the last year. "Frequent comprehensive testing" was defined as ≥3 of each test in the previous year. Participants reported STI diagnoses of chlamydia, gonorrhea, syphilis, and other STIs in the last year. Trends in testing and diagnoses from 2017 to 2020 and 2020 to 2021 were assessed with logistic regression models. RESULTS We analyzed 24,488 survey responses from participants reporting casual sex in the last 6 months. Between 2017 and 2020, frequent comprehensive STI testing decreased among HIV-negative GBM on preexposure prophylaxis (PrEP) from 71.7% to 68.9% and declined further to 58.6% in 2021. Frequent comprehensive STI testing was stable during 2017-2020 among HIV-negative/untested GBM not on PrEP (17.4%-14.6%) and HIV-positive GBM (30.4%-35.1%) but declined in 2021 to 7.5% among non-PrEP-users and 25.7% among HIV-positive participants. There were minimal changes in STI diagnoses during 2017-2020, but diagnoses declined in 2021. CONCLUSIONS Many GBM do not meet Australian STI testing guidelines that recommend quarterly testing. Further evaluation of whether this recommendation is realistic or necessary to reduce STIs among GBM is recommended.

Abstract
HIV self-testing allows people to collect samples and test themselves at home, addressing known barriers to facility-based testing. We aimed to measure the uptake of home HIV testing among Australian gay and bisexual men (GBM). Using national cross-sectional data from the Australian Gay Community Periodic Surveys, we assessed trends in home HIV testing among non-HIV positive GBM between 2018 and 2020. Overall, the use of home HIV testing was low, but slightly increased during 2018-2020 (from 0.3 to 0.8%, RR = 1.54, 95%CI = 1.23-1.92, p-trend < 0.001). Testing at home was more likely among non-HIV-positive GBM who were born overseas and recently arrived in Australia, at higher risk of HIV, and infrequent HIV testers. Given the greater use of home testing by men at higher risk of HIV, recent migrants and infrequent testers, all priority groups in Australia's HIV epidemic, we recommend increasing access to HIV self-testing to enhance uptake in these and other groups of GBM.

Abstract
BACKGROUND Asian gay, bisexual, and other men who have sex with men (GBMSM) are overrepresented in new HIV diagnoses in Australia. Social engagement with other GBMSM has been associated with HIV testing and pre-exposure prophylaxis (PrEP) uptake. Asian GBMSM may be socially disconnected from LGBTQ+ people, which may increase their HIV risk. This analysis assessed the contribution of social connection on HIV risk among Asian GBMSM. METHODS Using an online cross-sectional survey of Asian GBMSM in Australia, we measured condomless anal intercourse (CLAI) in the last 6months without PrEP or an undetectable viral load (UVL), i.e. CLAI with a risk of HIV transmission. Bivariable and multivariable logistic regression models were performed to compare demographic characteristics and social engagement of participants who had CLAI without PrEP or UVL to those who had not. Analyses were restricted to participants who reported sex with casual partners in the last 6months. RESULTS Among 509 participants who had casual partners in the last 6months, 151 (29.7%) reported CLAI without PrEP or UVL. CLAI without PrEP or UVL was negatively associated with full-time employment, and recently being tested for HIV and was positively associated with experiencing discrimination based on sexual orientation. Social engagement with LGBTQ+ people was not associated with CLAI without PrEP or UVL. CONCLUSIONS CLAI without PrEP or UVL was not related to social connections with LGBTQ+ people but was more likely among Asian men who had experienced sexuality-related discrimination, suggesting that mitigating homophobia and biphobia may assist in improving HIV prevention among Asian GBMSM who live in Australia.

Abstract
BACKGROUND In mid-2022, a global mpox (formerly 'monkeypox') outbreak affecting predominantly gay and bisexual men emerged in non-endemic countries. Australia had never previously recorded mpox cases and there was no prior research on knowledge or attitudes to mpox among gay and bisexual men across Australia. METHODS We conducted a national, online cross-sectional survey between August 2022 and September 2022. Participants were recruited through community organisation promotions, online advertising, and direct email invitations. Eligible participants were gay, bisexual or queer; identified as male (cisgender or transgender) or non-binary; aged 16years or older; and lived in Australia. The main outcome measures were: knowledge and concern about mpox; recognition of mpox symptoms and transmission routes; vaccination history; acceptability of behavioural changes to reduce mpox risk, and willingness to be vaccinated. RESULTS Of 2287 participants, most participants were male (2189/2287; 95.7%) and gay (1894/2287; 82.8%). Nearly all had heard about mpox (2255/2287; 98.6%), and the majority were concerned about acquiring it (1461/2287; 64.4%). Most of the 2268 participants not previously diagnosed with mpox correctly identified skin lesions (2087; 92%), rash (1977; 87.2%), and fever (1647; 72.6%) as potential symptoms, and prolonged and brief skin-to-skin contact as potential ways to acquire mpox (2124, 93.7%; and 1860, 82%, respectively). The most acceptable behavioural changes were reducing or avoiding attendance at sex parties (1494; 65.9%) and sex-on-premises venues (1503; 66.4%), and having fewer sexual partners (1466; 64.6%). Most unvaccinated and undiagnosed participants were willing to be vaccinated (1457/1733; 84.1%). CONCLUSIONS People at risk of mpox should be supported to adopt acceptable risk reduction strategies during outbreaks and to seek vaccination.

Abstract
OBJECTIVE To assess changes in personal and relationship characteristics among HIV-positive Australian gay and bisexual men (GBM) as rates of antiretroviral therapy and knowledge and confidence regarding the effectiveness of viral suppression in preventing HIV transmission have increased. DESIGN Repeated behavioral surveillance of GBM recruited from venues, events, and online in 7 Australian states and territories. METHODS HIV-positive participants were included. Trends in demographics, HIV treatment, and relationship characteristics were assessed with binary and multivariable logistic regression. RESULTS A total of 3643 survey responses (2016-2020) were included. Over time, HIV-positive GBM became less likely to identify as gay or report an Anglo-Australian ethnicity. The average length of time since HIV diagnosis increased and the frequency of attending HIV-related clinical appointments decreased. There were no changes in the reported number of recent sex partners or proportion reporting regular male partners over time. Among HIV-positive GBM in relationships, the proportion reporting HIV-positive partners decreased and the proportion reporting HIV-negative partners increased. Levels of condomless sex with regular partners increased over time; however, this was concentrated among HIV-positive GBM in serodiscordant relationships. CONCLUSION Findings suggest that increased accessibility and trust in biomedical prevention strategies have contributed to broader relationship and sexual opportunities for HIV-positive GBM in Australia. Our findings suggest that future health promotion activities could highlight the social and relationship benefits of treatment as prevention to further increase trust in it as an HIV prevention strategy among GBM.

Abstract
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.

Abstract
Pre-exposure prophylaxis (PrEP) is recommended for people susceptible to HIV acquisition, and the scale-up of PrEP programmes has contributed to new HIV case reductions at a population level. However, international migrants continue to be disproportionately affected by HIV. Understanding barriers and facilitators to PrEP implementation among international migrants can optimise PrEP use among this population and ultimately reduce HIV incidence worldwide. We reviewed the evidence regarding factors influencing PrEP implementation among international migrants; 19 studies were included. The barriers and facilitators at the individual level were related to knowledge and risk perception of HIV. Cost, provider discriminations, and health system navigation influenced PrEP use at the service level. Positive or negative perception towards LGBT+ identities, HIV, and PrEP users affected PrEP use at the societal level. Most existing PrEP campaigns do not target international migrants; therefore, culturally tailored approaches for people from different backgrounds are warranted. Potentially migration-related and HIV-related discriminatory policies must be reviewed to increase access to HIV prevention services to end HIV transmission at a population level.

Abstract
The HIV epidemic in Australia is changing with higher risk for HIV among newly-arrived Asian-born men who have sex with men (MSM) compared to Australian-born MSM. We evaluated the preferences for HIV prevention strategies among 286 Asian-born MSM living in Australia for <5 years. A latent class analysis uncovered three classes of respondents who were defined by their preferences: “PrEP” (52%), “Consistent condoms” (31%), and “No strategy” (17%). Compared to the “No strategy” class, men in the “PrEP” class were less likely to be a student or ask their partner for their HIV status. Men in the “Consistent condoms” class were more likely to get information about HIV from online, and less likely to ask their partner for their HIV status. Overall, PrEP was the preferred HIV prevention strategy for newly arrived migrants. Removing structural barriers to access PrEP can accelerate progress toward ending HIV transmission.

Attitudes Towards Treatment as Prevention Among PrEP-Experienced Gay and Bisexual Men in Australia. AIDS Behav 2023:10.1007/s10461-023-04019-x.

Abstract
The introduction of HIV pre-exposure prophylaxis (PrEP) has the potential to impact the attitudes gay and bisexual men (GBM) who consequently choose to take PrEP have towards treatment as prevention (TasP), and the extent to which they are willing to have condomless anal intercourse (CLAI) with an HIV-positive sexual partner who has an undetectable viral load (UVL). Using a cross-sectional sample from an observational cohort study conducted from August 2018 to March 2020, we examined the extent to which PrEP-experienced GBM are willing to have CLAI with a partner who has a UVL. Simple and multiple logistic regression models were used to identify associated variables. Of the 1386 participants included in the analyses, 79.0% believed in the effectiveness of TasP, and 55.3% were willing to have CLAI with a partner who has a UVL. Wiling participants were less worried about getting HIV when taking PrEP and more likely to believe in TasP. Further research is needed to better understand the gap between belief in TasP and willingness to have CLAI with a partner who has a UVL among PrEP-experienced GBM.

Abstract
We mapped gay and bisexual men's (GBM) patterns of using pre-exposure prophylaxis (PrEP) over time and explored sexual behavior as PrEP use changed. We conducted semi-structured interviews between June 2020 and February 2021 with 40 GBM living in Australia who had changed their PrEP use since initiating. There was considerable diversity in patterns of discontinuation, suspension, and recommencement of PrEP. Reasons for changing PrEP use mostly centered on accurate perceived changes to HIV risk. Twelve participants reported condomless anal intercourse with casual or fuckbuddy partners after discontinuing PrEP. These sex events were unanticipated, condoms were not a preferred option, and other risk reduction strategies were applied inconsistently. Service delivery and health promotion can support safer sex among GBM when PrEP use fluctuates by promoting event-driven PrEP and/or non-condom-based risk reduction methods during periods off daily PrEP, and guiding GBM to better recognize changing circumstances of risk and when to recommence PrEP.

Explicit Relationship Agreements and HIV Pre-exposure Prophylaxis Use by Gay and Bisexual Men in Relationships. ARCHIVES OF SEXUAL BEHAVIOR 2023; 52:761-771.

Abstract
Relationship agreements are important for HIV prevention among gay and bisexual men (GBM) in relationships, with research earlier in the HIV epidemic often finding that agreements specified monogamy or condom use with casual partners. There is evidence that HIV pre-exposure prophylaxis (PrEP) has shifted sexual practices among some men in relationships, such as allowing condomless sex with casual partners, but there has been little attention paid to relationship agreements among GBM who use PrEP. In this paper, we analyzed national, Australian, cross-sectional data from an online survey completed by non-HIV-positive GBM in 2021 (N = 1,185). Using logistic regression, we identified demographic characteristics, sexual practices and the types of relationship agreement that were associated with PrEP use among GBM in relationships. Using Pearson's chi-squared tests, we explored whether PrEP users in relationships reported similar sexual practices to PrEP users not in relationships. PrEP use among GBM in relationships was independently associated with older age, identifying as gay, being in a non-monogamous relationship, having a spoken (explicit) relationship agreement, having a primary HIV-negative partner taking PrEP or a primary partner living with HIV, reporting recent condomless casual sex, reporting an STI diagnosis in the past year, and knowing at least one other PrEP user. We found that PrEP users in relationships had similar sexual practices to PrEP users not in relationships. GBM in relationships who have casual sex and who meet PrEP suitability criteria may be good candidates for PrEP. Our findings suggest that explicit relationship agreements remain important for HIV prevention, and they support PrEP use among GBM in relationships.

Discontinuation of government subsidized HIV pre-exposure prophylaxis in Australia: a whole-of-population analysis of dispensing records. J Int AIDS Soc 2023; 26:e26056.

Abstract
INTRODUCTION HIV pre-exposure prophylaxis (PrEP) has been government subsidized in Australia since April 2018 and while uptake is high among men who have sex with men, rates of discontinuation are also high. The aims of this study were to examine the impact of discontinuation on overall PrEP usage, the proportion of PrEP users who discontinue and the predictors of discontinuation. METHODS We used linked de-identified dispensing records of all government subsidized PrEP in Australia between April 2018 and September 2021: a whole-of-population data set. Defining discontinuation as 180 days or more without PrEP after the final dispensed supply, we calculated the number of people who discontinued at each 6-month interval during the study period, the proportion who had discontinued 2 years after the first supply and, using Cox regression, predictors of discontinuation. RESULTS Of 49,164 people dispensed PrEP (98.5% male, median age 34 years), 40.3% (19,815) had discontinued by September 2021. Within 2 years of their first supply, 11,150 (37.7%) of 29,549 PrEP users had discontinued, including 10.0% after a single dispensed supply. Large variations were observed, particularly according to prescriber characteristics: discontinuation was higher among people prescribed PrEP by low caseload (≤10 patients) prescribers (61.2%) than by high caseload (>100 patients) prescribers (31.1%, p<0.001), and by prescribers practising in areas with low estimated prevalence (<1.0%) of gay men (64.1%) than high (>5%) prevalence (36.7%, p<0.001). Women and younger people were more likely to discontinue, while patients receiving a higher level of government subsidy were less likely. The independent predictors of discontinuation with the greatest effect size were female sex (adjusted hazards ratio [aHR] 2.99, p<0.001), low estimated gay prevalence of prescriber location (aHR 1.98, p<0.001) and low prescriber PrEP caseload (aHR 1.79, p<0.001). CONCLUSIONS There are high rates of PrEP discontinuation in Australia and some populations are at increased risk of discontinuation. Strategies are needed to support persistence on PrEP and the re-starting of PrEP during periods of risk.

Abstract
Objectives Gay, bisexual and other men who have sex with men (GBMSM) and trans and gender diverse (TGD) people are disproportionately affected by poorer sexual health outcomes compared to heterosexual populations. We aimed to explore the preferences of GBMSM and TGD for using eHealth for sexual health (eSexualHealth). Methods We distributed an anonymous online survey from April to August 2021among the lesbian, gay, bisexual, transgender, intersex, queer and other people of diverse sexuality or gender (LGBTIQA+) community in Australia. The survey collected data on sociodemographic characteristics and sexual behaviors, their preferences for app/website functions and preferred HIV and sexually transmitted infection (STI) testing reminders. We used descriptive statistics to summarize the characteristics of the study population. Free-text responses were thematically analyzed. Results Of 466 participants included, most identified as cisgender males (92.7%). The median age was 48 [interquartile range (IQR): 37-56]. For accessing sexual health-related information, 160 (34.6%) would use either a website or an app, 165 (32.7%) would prefer a website, 119 (25.8%) would prefer an app, and 33 (7.1%) would not use either platform. There was no significant difference between GBMSM and TGD people. Participants were most interested in information about STI clinics, HIV/STI hotspots, and sexual health education. Participants stressed the need for privacy and anonymity when using eHealth. Regarding reminders to test for HIV/STIs, receiving regular SMS was most popular (112/293, 38.2%), followed by regular emails (55/293 18.8%) and a reminder function on their phone (48/293, 16.4%). Conclusion Our study suggests a promising future for eHealth among GBMSM and TGD people. Sexual health is still a stigmatized area, and eHealth may circumvent barriers this population faces.

Abstract
COVID-19 has disrupted sexual behaviour and access to health systems. We adapted regular HIV behavioural surveillance of gay and bisexual men (GBM) in Australia in response to COVID-19, assessed the impact on the profile of the sample, the participants' HIV-related behaviour, and whether COVID-19 may have accentuated existing disparities in the Australian HIV epidemic. Data collected from five states during July 2017-June 2021 were included (N = 31,460). The emphasis on online recruitment after COVID-19 led to smaller sample sizes, greater geographic reach, and a higher proportion of bisexual-identifying participants. Most participants (88.1%) reported physical distancing and 52.1% had fewer sex partners due to COVID-19. In the COVID-19-affected rounds (July 2020-June 2021), the number of male partners, recent HIV testing and pre-exposure prophylaxis (PrEP) use all fell, and HIV risk among the smaller group of participants who reported casual sex increased. COVID-related changes were generally more pronounced among GBM aged under 25 years, participants from suburbs with fewer gay residents, and bisexual men. These groups should be prioritised when encouraging GBM to reengage with HIV testing services and effective prevention methods, like condoms and PrEP.

Abstract
BACKGROUND Recent changes to Australian PrEP prescribing guidelines support the use of event-driven pre-exposure prophylaxis (ED-PrEP) to prevent HIV among gay and bisexual men (GBM). Social marketing campaigns to increase awareness of ED-PrEP were conducted in early 2021. This study aimed to assess the awareness and knowledge of this method after these campaigns. METHODS We conducted a national cross-sectional online survey about PrEP knowledge and attitudes from March to May 2021. Participants were asked if they had heard of ED-PrEP. Among aware participants, questions about the '2-1-1' method were asked to assess knowledge. Bivariate and multivariate logistic regression analyses were conducted to assess the characteristics of those who were aware of ED-PrEP, and those who had correct knowledge of ED-PrEP. Analysis was restricted to non-HIV-positive cis-GBM who were aware of PrEP. RESULTS Among the 419 participants eligible for this analysis, 286 (68.3%) had heard of ED-PrEP. Awareness was associated with living in a postcode with ≥10% gay men, PrEP experience, and belief ED-PrEP is effective. Of these 286 participants, 125 (43.7%) correctly answered questions about how to take ED-PrEP. Correct knowledge was associated with PrEP experience and belief ED-PrEP is effective. CONCLUSIONS A growing proportion of GBM are aware of ED-PrEP, but many still do not know how to take it as per clinical guidelines. More work is needed to increase knowledge among GBM to promote effective use of this method.

Abstract
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.
