HIV Pre-exposure Prophylaxis (PrEP) Uptake Among Gay and Bisexual Men in Australia and Factors Associated With the Nonuse of PrEP Among Eligible Men: Results From a Prospective Cohort Study

Sexual and preventive behaviors associated with HAV, HBV, and HPV vaccine hesitancy among men who have sex with men in France

Vaccination coverage against hepatitis A virus (HAV), hepatitis B virus (HBV), and human papillomaviruses (HPV) is insufficient among men who have sex with men (MSM), partly because of their high prevalence of vaccine hesitancy (VH) specific to these vaccines. This study aimed to investigate determinants of specific VH in MSM, focusing on characteristics of their sexual activity, propensity to use prevention tools and medical care, disclosure of sexual orientation to health care professionals (HCPs), and perceived stigmatization. A cross-sectional electronic survey (February - August 2022) collected perceptions of HBV, HAV, and HPV, and of their respective vaccines among 3,730 French MSM and enabled the construction of a specific VH variable. Using agglomerative hierarchical cluster analysis, we constructed a typology of MSM sexual and prevention practices. We identified three MSM clusters (low- (C1, 24%), moderate- (C2, 41%), and high- (C3, 35%) "sexual activity/medical engagement") that showed an increasing gradient in the use of medical prevention with regular medical care and exposure to high-risk sexual practices. A multiple ordinal logistic regression showed that overall specific VH was higher in the C1 cluster and in men who had not informed their physician of their sexual orientation. This typology could usefully help to adapt vaccination communication strategies for MSM prevention program according to patients' profiles. HCPs should be encouraged and trained to ask men about their sexual practices and to provide appropriate vaccination recommendations nonjudgmentally.

Missed Opportunity or Cause for Concern? Methamphetamine Use Is Associated With Greater Interest in Event-Driven PrEP Among Sexual Minority Men

Our study assessed the association between methamphetamine (i.e., crystal meth, CM) use and awareness and interest in event-driven (ED) PrEP among HIV-negative and those with unknown serostatus cisgender males and transgender people. We performed log-binomial regression analysis to predict awareness (i.e., having heard of ED PrEP) and being interested in ED PrEP. We found that participants who recently used CM were less likely to know of ED PrEP (aPR = 0.83, 95% CI [0.69, 0.99]) but more interested in ED PrEP (aPR = 1.12, 95% CI [1.01, 1.30]), after accounting for demographic and HIV-related behaviors. Opportunities to expand PrEP uptake and improve adherence among individuals who report CM use are essential to impact the HIV epidemic significantly. Continued research on the needs and best practices to work with this community is needed to ensure a successful rollout and implementation of ED PrEP.

Gay community involvement and the sexual health behaviours of sexual minority men: a systematic review and directions for future research

Considerable research has examined how involvement in gay-affiliated communities is associated with sexual health behaviours in sexual minority men (i.e., gay, bisexual, and other men who have sex with men), yet findings in this domain are often contradictory and inconclusive. This systematic review aimed to (a) synthesise the related empirical literature, and (b) identify potential factors driving inconsistent findings. Peer-reviewed publications were included if they contained quantitative data and at least one measure of the statistical association between gay community involvement and sexual health behaviour. The search strategy was implemented in six databases and returned 6,409 articles, of which 86 met the inclusion criteria. There was considerable heterogeneity in how gay community involvement was assessed across studies. Although gay community involvement was consistently associated with greater engagement in protective behaviours across studies, the association between gay community involvement and risk behaviours appeared to depend on how gay community involvement was conceptualised and measured (e.g., nightlife involvement vs. political activism). Findings emphasise a need for studies that employ validated measures that reflect the multidimensional nature of gay community involvement, as well as research designs better suited to address the causal effects of community involvement on HIV/STI transmission and prevention.

Molecular epidemiology to aid virtual elimination of HIV transmission in Australia

The Global UNAIDS 95/95/95 targets aim to increase the percentage of persons who know their HIV status, receive antiretroviral therapy, and have achieved viral suppression. Achieving these targets requires efforts to improve the public health response to increase access to care for those living with HIV, identify those yet undiagnosed with HIV early, and increase access to prevention for those most at risk of HIV acquisition. HIV infections in Australia are among the lowest globally having recorded significant declines in new diagnoses in the last decade. However, the HIV epidemic has changed with an increasing proportion of newly diagnosed infections among those born outside Australia observed in the last five years. Thus, the current prevention efforts are not enough to achieve the UNAIDS targets and virtual elimination across all population groups. We believe both are possible by including molecular epidemiology in the public health response. Molecular epidemiology methods have been crucial in the field of HIV prevention, particularly in demonstrating the efficacy of treatment as prevention. Cluster detection using molecular epidemiology can provide opportunities for the real-time detection of new outbreaks before they grow, and cluster detection programs are now part of the public health response in the USA and Canada. Here, we review what molecular epidemiology has taught us about HIV evolution and spread. We summarize how we can use this knowledge to improve public health measures by presenting case studies from the USA and Canada. We discuss the successes and challenges of current public health programs in Australia, and how we could use cluster detection as an add-on to identify gaps in current prevention measures easier and respond quicker to growing clusters. Lastly, we raise important ethical and legal challenges that need to be addressed when HIV genotypic data is used in combination with personal data.

Trends in illicit drug use and their association with HIV transmission risks from behavioural surveillance of Australian gay and bisexual men

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.

Pre-exposure prophylaxis access, uptake and usage by young people: a systematic review of barriers and facilitators

Background

Young people's sexual health decision-making, including decisions to access and adhere to HIV prevention strategies such as Pre-Exposure Prophylaxis (PrEP), are influenced by a range of internal and external factors. Synthesizing these factors is essential to guide the development of youth-focused PrEP health promotion strategies to contribute to international goals of ending HIV transmission.

Objective

To understand the individual, interpersonal, sociocultural and systemic barriers and facilitators to PrEP access, uptake and use experienced by young people 24 years and younger.

Design

A systematic review that adhered to the Preferred Reporting Items of Systematic Review and Meta-Analysis Protocols.

Data Sources and Methods

Eight databases (PubMed, Scopus, Cochrane, Medline, CINAHL, JBI, EMBASE, Web of Science) were systematically searched using terms related to young people, HIV and PrEP use. A narrative synthesis approach was used to delineate key barriers and facilitators to PrEP access, uptake and use.

Results

Of 11,273 returned articles, 32 met the eligibility criteria for inclusion: 18 from the United States, 10 from African nations and two from Brazil. Barriers and facilitators to PrEP access, uptake and use experienced by young people were identified across intrapersonal, interpersonal, community and systems levels. These factors are described under four overarching themes that relate to knowledge, side effects and perceptions of risk; attitudes and perceptions of family and partners; community attitudes and stigma; and negative healthcare provider experiences and difficulties navigating complex costly healthcare systems.

Conclusion

Findings suggest individual-level factors need consideration alongside the impacts of healthcare systems and broader systemic sociocultural structures within young people's relationships when developing PrEP health promotion strategies and services. Without considering these wider external implications to access, uptake and use of PrEP, global targets towards the elimination of HIV transmission will likely remain out of reach.

Addressing disparities in Pre-exposure Prophylaxis (PrEP) access: implementing a community-centered mobile PrEP program in South Florida

BACKGROUND

Pre-exposure prophylaxis (PrEP) for HIV prevention is highly effective, but disparities in PrEP access remain considerable, particularly among Black and Latino men who have sex with men (MSM). To address this, the University of Miami Mobile PrEP Program was created, offering mobile HIV prevention/PrEP services in areas throughout South Florida where HIV incidence is high and PrEP access is geographically limited. Using a community-centered participatory approach, the program strategized and executed expansion into the Liberty City neighborhood of Miami. This study qualitatively assessed factors affecting Mobile PrEP implementation as perceived by community stakeholders, clients, and program staff.

METHODS

Forty-one in-depth interviews were conducted with 21 Mobile PrEP clients, 10 key informants from local health organizations, and 10 program staff. Interview questions queried perceived organizational and positional barriers and facilitators to mobile clinic implementation. Service satisfaction, setting preferences, social factors, and likelihood of recommending Mobile PrEP were also assessed. A thematic content analysis was performed using the Consolidated Framework for Implementation Research (CFIR) taxonomy as the guiding constructs for the analysis.

RESULTS

Participant statements indicated that providing no-cost services, convenient location, program-covered rideshares, individualized patient navigation, and a community-centric approach to patient care, which included staff members with shared lived experiences to increase positive interactions and renewed trust among poorly served communities, were facilitators of PrEP access and intervention uptake. The importance of program familiarization with the community before implementation, particularly for Black and African American communities, who may experience unique barriers to accessing sexual healthcare was strongly emphasized by participants.

CONCLUSIONS

The Mobile PrEP intervention was found to be an acceptable and accessible mode of HIV/STI preventive care. The importance of pre-implementation community engagement and preparation is emphasized. Future research is needed to refine understanding of the intervention's components and evaluate implementation determinants in other highly impacted neighborhoods.

Motivational Enhancement Interventions to Increase Pre-Exposure Prophylaxis Use in Sexual Minority Men Who Use Stimulants: Protocol for a Pilot Sequential Multiple Assignment Randomized Trial

BACKGROUND

Although pre-exposure prophylaxis (PrEP) could substantially mitigate HIV risk, sexual minority men who use stimulants commonly experience difficulties with engaging in PrEP clinical services. Motivational interviewing (MI) and contingency management (CM) reduce substance use and condomless anal sex (CAS) in this population, but these motivational enhancement interventions require modifications to promote engagement along the PrEP care continuum.

OBJECTIVE

PrEP Readiness Interventions for Supporting Motivation (PRISM) is a pilot sequential multiple assignment randomized trial testing the feasibility, acceptability, and preliminary effectiveness of distinct combinations of telehealth MI and CM in 70 cisgender sexual minority men who use stimulants that are not currently taking PrEP.

METHODS

A national sample was recruited via social networking applications to complete a baseline assessment and mail-in HIV testing. Those with nonreactive HIV results were randomized to receive either (1) a 2-session MI intervention focusing on PrEP use (session 1) and concomitant stimulant use or CAS (session 2) or (2) a CM intervention with financial incentives for documented evidence of PrEP clinical evaluation by a medical provider (US $50) and filling a PrEP prescription (US $50). At the 3-month follow-up assessment, participants who reported they had not filled a prescription for PrEP were randomized a second time to either (1) switch to a second-stage intervention (ie, MI+CM or CM+MI) or (2) continue with assessments only. Outcomes for both responders and nonresponders were reassessed at a 6-month follow-up. The primary outcome is documented evidence of filling a PrEP prescription over 6 months. Self-reported secondary outcomes include PrEP clinical evaluation by a medical provider, stimulant use, and CAS. Qualitative exit interviews were conducted with a subgroup of responders and nonresponders to characterize their experiences with the MI and CM interventions.

RESULTS

Implementation of PRISM underscores challenges in reaching sexual minority men who use stimulants to optimize HIV prevention efforts. Approximately 1 in 10 (104/1060) eligible participants have enrolled. Of the 104 who enrolled, 87 (84%) completed mail-in HIV testing. We delivered 5 preliminary HIV-positive results, including posttest counseling with referrals to confirmatory testing.

CONCLUSIONS

Lessons learned from PRISM underscore the central importance of a flexible, participant-centered approach to support the engagement of sexual minority men who use stimulants. Leveraging telehealth platforms to deliver motivational enhancement interventions also expanded their reach and potential public health impact with this high-priority population. Further research is needed to determine the effectiveness of telehealth MI and CM for supporting PrEP use in sexual minority men who use stimulants.

People living with HIV who inject or have injected non-prescription drugs: Evidence of substantial differences in health inequalities and experiences of clinical care

INTRODUCTION

This study investigates differences in health and well-being associated with current, past or no injecting drug use (IDU) among people living with HIV (PLHIV) in Australia, identifying key health care considerations between injecting experiences.

METHODS

Data were extracted from the HIV Futures 9 study; a survey of PLHIV conducted in 2018-2019. Chi-square and analysis of variance analyses compared clinical and treatment characteristics, major physical and mental comorbidities, sexually transmitted infection diagnoses, and quality of life for those who reported current (last 12 months), past (12+ months ago) or no IDU.

RESULTS

Current IDU (n = 106) was associated with higher rates of sexually transmitted infection testing and diagnoses, higher frequency of self-reported antiretroviral therapy non-adherence due to drug use and greater social quality of life than past (n = 126) or no IDU (n = 508; total N = 740). Past and current IDUs were associated with more mental illness diagnoses and self-reported concern about drug use. Past IDU was associated with more physical comorbidities, lower satisfaction with clinical care and greater difficulty in affording health care than current or no IDU.

DISCUSSION AND CONCLUSIONS

Past and current IDUs are associated with unique health concerns. However, past IDU appears to be related to greater dissatisfaction in navigating health care than individuals with current IDU experience. Higher social connection and the types of services being accessed by individuals who currently inject may play a role in shaping service satisfaction. Peer-based interventions to help support individuals in accessing services that are affirming of their needs is an ongoing priority.

Reasons for not Using HIV Pre-Exposure Prophylaxis (PrEP) among Gay and Bisexual Men in Australia: Mixed-Methods Analyses from a National, Online, Observational Study

Although approximately 31,000 Australian gay and bisexual men (GBM) are eligible for HIV pre-exposure prophylaxis (PrEP), only 18,500 people currently use it, indicating a need to investigate why GBM do not use it. This article uses data from a national, online, observational study. It adopts a mixed-methods analysis to responses to survey questions asking about reasons Australian GBM were not using PrEP in 2018, according to their level of HIV risk as delineated by the Australian PrEP prescribing guidelines at the time. Participants responded to check-box questions and had the option to respond to a qualitative free-text question. Results showed that just over one-fifth of men were at higher risk of HIV acquisition. Compared to lower-risk men, higher-risk men were more likely to indicate PrEP was too expensive and more likely to cite embarrassment asking for it. Reasons for not using PrEP included a lack of personal relevance, poor accessibility or knowledge, concerns about PrEP's inability to protect against STIs, potential side effects, and a preference for condoms. We conclude that health promotion more effectively targeting GBM who may benefit the most from PrEP may be valuable.

Binge Drinking Moderates Unprotected Sex Among HIV Sero-Similar Same Sex Male Couples: An Actor-Partner Interdependence Model

Most new HIV diagnoses in the US occur among sexual minority men (SMM). The majority (69%) of new HIV diagnoses among US SMM are due to transmission from main sex partners. We identified multilevel correlates of unprotected anal intercourse (UAI; condomless anal intercourse while not using a biomedical strategy) among SMM couples using the Actor Partner Interdependence Model (APIM). Participants were US SMM over 18 years, with a primary male partner > 6 months. Couples were recruited online from April 2016 until June 2017 and interviewed using self-administered computer-assisted surveys. We used a series of APIM regressions to assess multilevel associations with UAI. We also tested the moderating role of an individual's binge drinking on the relationship between HIV status similarity and UAI. Among 798 participants (n = 411 couples), 61% reported UAI in the past 6 months. Binge drinking (52%) and physical intimate partner violence (IPV; 34%) were considerably high within our sample. Actor's binge drinking, reporting experiencing and/or perpetrating physical IPV, and partner's trust were positively associated with UAI. Actor having other sexual partner(s), using illegal drugs (not marijuana), and length of relationship were negatively associated with UAI. Binge drinking positively moderated UAI among HIV serostatus similar partners. HIV prevention programming should integrate components on IPV and binge drinking reduction- especially among HIV serostatus similar couples.

Addressing Disparities in Pre-Exposure Prophylaxis (PrEP) Access: Implementing a Community-Centered Mobile PrEP Program in South Florida

Background

Pre-exposure prophylaxis (PrEP) for HIV prevention is highly effective, but disparities in PrEP access remain considerable, particularly among Black and Latino men who have sex with men (MSM). To address this, the University of Miami Mobile PrEP Program was created, offering mobile HIV prevention/PrEP services in areas throughout South Florida where HIV incidence is high and PrEP access is geographically limited. Using a community-centered participatory approach, the program strategized and executed expansion into the Liberty City neighborhood of Miami. This study qualitatively assessed factors affecting Mobile PrEP implementation as perceived by community stakeholders, clients, and program staff.

Forty-one in-depth interviews were conducted with 21 Mobile PrEP clients, 10 key informants from local health organizations, and 10 program staff. Interview questions queried perceived organizational and positional barriers and facilitators to mobile clinic implementation. Service satisfaction, setting preferences, social factors, and likelihood of recommending Mobile PrEP were also assessed. A thematic content analysis was performed using the Consolidated Framework for Implementation Research (CFIR) taxonomy as the guiding constructs for the analysis.

Results

Participant statements indicated that providing no-cost services, convenient location, program-covered rideshares, individualized patient navigation, and a community-centric approach to patient care, which included staff members with shared lived experiences to increase positive interactions and renewed trust among poorly served communities, were facilitators of PrEP access and intervention uptake. The importance of program familiarization with the community before implementation, particularly for Black and African American communities, who may experience unique barriers to accessing sexual healthcare was strongly emphasized by participants.

Conclusions

The Mobile PrEP intervention was found to be an acceptable and accessible mode of HIV/STI preventive care. The importance of pre-implementation community engagement and preparation is emphasized. Future research is needed to refine understanding of the intervention's components and evaluate implementation determinants in other highly impacted neighborhoods.

Randomized Controlled Trial of Motivational Enhancement Interventions to Increase Pre-Exposure Prophylaxis Use in Sexual Minority Men Who Use Stimulants

Background

Although pre-exposure prophylaxis (PrEP) could substantially mitigate HIV risk, sexual minority men (SMM) who use stimulants commonly experience difficulties with engaging in PrEP clinical services. Motivational interviewing (MI) and contingency management (CM) reduce substance use and condomless anal sex in this population, but these motivational enhancement interventions require adaptation to promote engagement along the PrEP care continuum.

Methods

PRISM is a pilot sequential multiple assignment randomized trial (SMART) testing the feasibility, acceptability, and preliminary effectiveness of distinct combinations of telehealth MI and CM in 70 cisgender SMM who use stimulants that are not currently taking PrEP. A national sample was recruited via social networking applications to complete a baseline assessment and mail-in HIV testing. Those with non-reactive HIV results are randomized to receive either: 1) a 2-session MI intervention focusing on PrEP use (session 1) and concomitant stimulant use or condomless anal sex (session 2); or 2) a CM intervention with financial incentives for documented evidence of PrEP clinical evaluation by a medical provider ($50) and filling a PrEP prescription ($50). At the 3-month follow-up assessment, participants who report they have not filled a prescription for PrEP are randomized a second time to either: 1) Switch to a second-stage intervention (i.e., MI + CM or CM + MI); or 2) Continue with assessments only. Outcomes for both responders and non-responders are reassessed at a 6-month follow-up. The primary outcome is documented evidence of filling a PrEP prescription. Self-reported, secondary outcomes include PrEP clinical evaluation by a medical provider, stimulant use, and condomless anal sex. Qualitative exit interviews are conducted with a sub-group of responders and non-responders to characterize their experiences with the MI and CM interventions.

Discussion

Implementation of this pilot SMART underscores the challenges in reaching SMM who use stimulants to optimize HIV prevention efforts such that approximately one in ten (104/1,060) eligible participants enrolled. However, 85% (70/82) of enrolled participants with non-reactive HIV results were randomized. Further research is needed to determine the effectiveness of telehealth MI and CM for supporting PrEP use in SMM who use stimulants.

Preferences for HIV prevention strategies among newly arrived Asian-born men who have sex with men living in Australia: A discrete choice experiment

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 &lt;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

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.

COVID-19 Testing in a Weekly Cohort Study of Gay and Bisexual Men: The Impact of Health-Seeking Behaviors and Social Connection

Gay, bisexual, and other men who have sex with men (GBM) have developed community norms for regular HIV/STI testing. We investigated factors associated with self-reported COVID-19 testing in response to reported COVID-19 cases and public health restrictions. Participants responded to weekly cohort surveys between 10th May 2021 and 27th September 2021. We used the Andersen-Gill extensions to the Cox proportional hazards model for multivariable survival data to predict factors influencing COVID-19 testing. Mean age of the 942 study participants was 45.6 years (SD: 13.9). In multivariable analysis, GBM were more likely to report testing during periods of high COVID-19 caseload in their state of residence; if they were younger; university educated; close contact of someone with COVID-19; or reported coping with COVID-19 poorly. COVID-19 testing was higher among men who: were more socially engaged with other GBM; had a higher proportion of friends willing to vaccinate against COVID-19; and were willing to contact sexual partners for contact tracing. Social connection with other gay men was associated with COVID-19 testing, similar to what has been observed throughout the HIV epidemic, making community networks a potential focus for the promotion of COVID-19 safe practices.

Explicit Relationship Agreements and HIV Pre-exposure Prophylaxis Use by Gay and Bisexual Men in Relationships

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

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.

Adjusting Behavioural Surveillance and Assessing Disparities in the Impact of COVID-19 on Gay and Bisexual Men's HIV-Related Behaviour in Australia

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.

Loss to Follow-Up from HIV Pre-Exposure Prophylaxis Care in Men Who Have Sex with Men in West Africa

Loss to follow-up (LTFU) from HIV pre-exposure prophylaxis (PrEP) care compromises the goal of HIV elimination. We investigated the proportion of LTFU and associated risk factors among men who have sex with men (MSM) enrolled in a PrEP demonstration project in Burkina Faso, Côte d'Ivoire, Mali, and Togo. CohMSM-PrEP, a prospective cohort study, was conducted between November 2017 and June 2021 in community-based clinics. MSM aged 18 years or older at substantial risk of HIV infection received a comprehensive prevention package, including PrEP and peer education. LTFU was defined as not returning to the clinic for six months. Associated risk factors were investigated using a time-varying Cox's model. Of 647 participants followed up for a median time of 15 months, 372 were LTFU (57.5%). LTFU was associated with younger age (adjusted hazard ratio [95% Confidence Interval]; 1.50 [1.17-1.94]), unemployment (1.33 [1.03-1.71]), depression (1.63 [1.12-2.38]), and perceiving no HIV risk with stable male partners (1.61 [1.23-2.10]). Contacting peer educators outside of scheduled visits was protective (0.74 [0.56-0.97]). Our findings show that LTFU from PrEP care in West African MSM is a major challenge to achieving HIV elimination, but that the involvement of peer educators in PrEP delivery helps to limit LTFU by providing users with adequate support.

Socio-behavioral correlates of pre-exposure prophylaxis use and correct adherence in men who have sex with men in West Africa

BACKGROUND

Multiple barriers compromise pre-exposure prophylaxis (PrEP) engagement (i.e., use and adherence) in men who have sex with men (MSM). In low/middle-income countries, little is known about PrEP engagement in this population. In West Africa, the CohMSM-PrEP study was one of the rare interventions providing PrEP to MSM. We estimated PrEP use and correct adherence rates in CohMSM-PrEP, together with associated factors over time.  METHODS: CohMSM-PrEP recruited MSM in four community-based clinics in Mali, Côte d'Ivoire, Burkina Faso, and Togo. Quarterly follow-up included collecting socio-behavioral data, and providing a comprehensive HIV prevention package, PrEP (daily or event-driven), and peer educator (PE)-led counselling. Using repeated measures, multivariate generalized estimating equations models were used to identify factors associated with self-reported i) PrEP use and ii) correct PrEP adherence during participants' most recent anal intercourse (defined as four pills/week for daily users and 2 + 1 + 1 for event-driven users).

RESULTS

Five hundred twenty participants were included with a median follow-up time of 12 months (IQR 6-21). Of the 2839 intercourses declared over the follow-up period, PrEP use was self-reported for 1996 (70%), and correct PrEP adherence for 1461 (73%) of the latter. PrEP use was higher in participants who also attended participating clinics outside of scheduled visits (adjusted odds ratio (aOR) [95% Confidence Interval, CI], p-value; 1.32[1.01-1.71], 0.040), and in those who practiced condomless anal sex (1.86[1.54-2.24], < 0.001). Correct adherence was higher in those who often contacted PE outside of scheduled visits (2.16[1.01-4.64], 0.047) and in participants who adopted receptive/versatile sexual positions with stable partners (1.36[1.03-1.81], 0.030). Instead, after an interaction effect between financial situation and regimen was tested, it was lower in event-driven users with a difficult/very difficult financial situation (comfortable/just making ends meet & daily, 4.19[2.56-6.86], < 0.001; difficult/very difficult & daily, 6.47[4.05-10.30], < 0.001; comfortable/just making ends meet & event-driven, 1.63[1.22-2.17], 0.001), and in participants who felt alone (0.76[0.58-0.99], 0.042).

CONCLUSIONS

Community-based clinic attendance and PE contact outside of scheduled visits were both associated with higher PrEP engagement, but some socially and economically marginalized participants struggled with adherence. As scale-up continues in West Africa, we recommend implementing community-based interventions and providing extra support for vulnerable users to ensure adequate PrEP engagement.

"How PrEPared are you?": Knowledge of and attitudes toward PrEP among overseas-born and newly arrived gay, bisexual, and other men who have sex with men in Australia

Introduction

Overseas-born and newly arrived gay and bisexual men and men who have sex with men (GBMSM) are at higher risk of acquiring HIV in comparison to Australian-born GBMSM. Pre-exposure prophylaxis (PrEP) is subsidized by the Australian government under Medicare, Australia's universal health insurance scheme, however many members of this population are Medicare-ineligible, which could prevent them from accessing PrEP. We wanted to explore participants' knowledge of and attitudes toward PrEP and their opinions of new PrEP modalities, namely injectable PrEP and PrEP implants.

Methods

We conducted in-depth qualitative interviews between February 2021 to September 2021 with 22 overseas-born, newly arrived (<5 years in Australia) GBMSM of varying PrEP use. We asked their opinions of PrEP and their preferences of new PrEP modalities. Interviews were audio recorded and transcribed verbatim. We conducted a reflexive thematic analysis to interpret the data.

Results

Participants' views reflect the intersections between systemic factors, such as Medicare ineligibility and the high cost of PrEP, with socio-cultural factors, such as lack of knowledge about PrEP, internalized stigma stemming from homo- and sex-negativity, and stigmatizing attitudes toward PrEP and PrEP users. For participants who were on PrEP, being community connected, having a positive relationship with doctors and nurses, and being informed of the option to purchase PrEP from overseas pharmacies at a low cost helped them to overcome some of these barriers. Additionally, there was a strong preference for injectable PrEP but not PrEP implants. Participants stressed the importance of providing a comprehensive information about PrEP specific to this population and to make PrEP free for all.

Conclusions

We concluded that resources about PrEP specific to this population that address both systemic and socio-cultural factors are needed, and for these resources to be available in languages other than English. This is to coincide with on-going advocacy to increase the capacity of publicly funded sexual health clinics to provide multilingual PrEP services for people without Medicare, and to make PrEP free for all. These combined strategies have the potential to increase PrEP knowledge and uptake among this population.

Trust, Familiarity, Optimism, and Pleasure: Australian Gay Men Accounting for Inconsistent HIV Prevention Practices in the PrEP Era

Despite an increase in the range of effective HIV risk reduction strategies that are available, some gay and bisexual men (GBM) do not use any of them consistently. Understanding why GBM do not always use a protective strategy may help develop more effective responses. Semi-structured interviews with 24 sexually active GBM in Sydney, Australia were conducted and analyzed using thematic analysis. The main characteristics of encounters featuring little or no use of HIV risk reduction strategies were familiarity and trust with partners, pleasure and intoxication, expectations that partners were using HIV pre-exposure prophylaxis or treatment as prevention, and in some cases feelings of inevitability about acquiring HIV. An increase in pleasure and a reduction in anxiety about sex were noted by some GBM who had commenced PrEP. Encouraging GBM to adopt a strategy such as PrEP and to use it consistently may be easier by emphasizing benefits to mental health and the quality of sex and intimacy it can offer. However, even with the increased availability of effective biomedical HIV risk reduction strategies, not all GBM are able to consistently manage HIV risk and some continue to hold optimistic and potentially inaccurate beliefs about sexual partners that may increase HIV risk.

Switching to Non-daily Pre-exposure Prophylaxis Among Gay and Bisexual Men in Australia: Implications for Improving Knowledge, Safety, and Uptake

INTRODUCTION

Preexposure prophylaxis (PrEP) dosing options such as event-driven PrEP hold promise to increase PrEP uptake among gay, bisexual, and queer men (GBQM), but their impacts have not yet been realized and uptake by GBQM suitable for PrEP remains slow in countries where it is only considered an alternative option to daily PrEP.

METHODS

We conducted semi-structured interviews between June 2020 and February 2021 with 40 GBQM in Australia to understand PrEP dosing behaviors, knowledge, and preferences.

RESULTS

All participants commenced PrEP daily; 35% had ever switched to non-daily PrEP, mostly taking it event-driven. GBQM who preferred non-daily PrEP had infrequent or predictable sex, were concerned about cost given infrequency of sex, and/or wanted to minimize unnecessary drug exposure. Accurate knowledge of event-driven PrEP was poor. However, reflecting concepts underpinning critical pedagogy, having accurate knowledge was supported by access to consistent messaging across clinical, social, community, and public settings. Several participants who switched to event-driven PrEP had condomless sex events in which they were unable to adhere to pills due to unanticipated sex.

CONCLUSIONS AND POLICY IMPLICATIONS

Implementation of comprehensive and consistent education about correct dosing for event-driven PrEP across multiple settings is needed to ensure increased uptake and safe use. GBQM require messaging about non-condom based HIV prevention strategies when they cannot access daily or event-driven PrEP.

Running with Scissors: a Systematic Review of Substance Use and the Pre-exposure Prophylaxis Care Continuum Among Sexual Minority Men

Purpose of Review

Patterns of sexualized drug use, including stimulants (e.g., methamphetamine) and chemsex drugs, are key drivers of HIV incidence among sexual minority men (SMM). Although pre-exposure prophylaxis (PrEP) mitigates HIV risk, there is no consensus regarding the associations of substance use with the PrEP care continuum.

Recent Findings

SMM who use substances are as likely or more likely to use PrEP. Although SMM who use stimulants experience greater difficulties with daily oral PrEP adherence, some evidence shows that SMM who use stimulants or chemsex drugs may achieve better adherence in the context of recent condomless anal sex. Finally, SMM who use substances may experience greater difficulties with PrEP persistence (including retention in PrEP care).

Summary

SMM who use stimulants and other substances would benefit from more comprehensive efforts to support PrEP re-uptake, adherence, and persistence, including delivering behavioral interventions, considering event-based dosing, and providing injectable PrEP.

Rate and Predictors of Ineffective HIV Protection in African Men Who Have Sex with Men Taking Pre-Exposure Prophylaxis

We investigated the rate and predictors of ineffective HIV protection in men who have sex with men (MSM) taking pre-exposure prophylaxis (PrEP) in a prospective cohort study from November 2017 to November 2020 in Mali, Côte d'Ivoire, Burkina Faso, and Togo. MSM had to be 18 years or older and at high risk of HIV infection to participate. They also received a comprehensive sexual health prevention package, including PrEP, in community-based clinics as part of the cohort study. Using socio-behavioral/clinical data, HIV protection during their most recent anal intercourse with a male partner was categorized as effective or ineffective (i.e., incorrect PrEP adherence and no condom use). Seventeen percent (500/2839) of intercourses were ineffectively protected for the 520 study participants. Predictors of ineffective HIV protection included being an event-driven user with financial difficulties, having a high alcohol misuse score, and not being a member of a community association. PrEP programs in West Africa must be tailored to socially vulnerable MSM who struggle to adopt PrEP.

COVID-19 Vaccine Uptake and Its Impacts in a Cohort of Gay and Bisexual Men in Australia

Successful use of biomedical forms of HIV risk-reduction may have predisposed many gay and bisexual men (GBM) to vaccination against COVID-19, which may, in turn, affect their sexual behavior. A total of 622 Australian GBM provided weekly data on COVID-19 vaccination history and sexual behaviour between 17 January 2021 and 22 June 2021. We identify factors associated with COVID-19 vaccination, and compare sexual behavior before and since vaccination. Mean age was 47.3 years (SD 14.0). At least one-dose vaccination coverage had reached 57.2%, and 61.3% reported that the majority of their friends intended to be vaccinated. Vaccinated men reported a mean of 1.11 (SD 2.10) weekly non-relationship sex partners before vaccination and 1.62 (SD 3.42) partners following vaccination. GBM demonstrated high confidence in COVID-19 vaccines. Their sexual activity increased following vaccination suggesting that greater sexual freedom may be a specific motivation for vaccine uptake among some men.

Increase in Depression and Anxiety Among Australian Gay and Bisexual Men During COVID-19 Restrictions: Findings from a Prospective Online Cohort Study

We examined depression and anxiety prior to and during COVID-19 restrictions in Australian gay and bisexual men (GBM). In an online cohort, a COVID-19-focused survey was conducted in April 2020. During 2019 and in April 2020, 664 GBM completed the Patient Health Questionnaire (PHQ-9, measuring depression) and Generalized Anxiety Disorder Assessment (GAD-7, measuring anxiety). Increased depression and anxiety were defined as a ≥ 5 point increase on the respective scales. Mean PHQ-9 and GAD-7 scores increased between 2019 and 2020 (PHQ-9: from 5.11 in 2019 to 6.55 in 2020; GAD-7: from 3.80 in 2019 to 4.95 in 2020). The proportion of participants with moderate-severe depression (PHQ-9 ≥ 10) increased from 18.8% (n = 125) to 25.5% (n = 169), while the proportion of participants with moderate-severe anxiety (GAD-7 ≥ 10) increased from 12.7% (n = 84) to 17.3% (n = 115). Almost one-quarter of participants (n = 158, 23.8%) had increased depression; in these men, mean PHQ-9 increased from 2.49 in 2019 to 11.65 in 2020 (p < 0.001). One-in-five (20.6%) participants (n = 137) had increased anxiety; among these men, mean GAD-7 increased from 2.05 in 2019 to 10.22 in 2020 (p < 0.001). Increases were associated with concerns about job security, reduction in social and sexual connections and opportunities, and being personally concerned about COVID-19 itself. COVID-19 appeared to have a sudden and pronounced impact on depression and anxiety in Australian GBM, with a significant minority showing sharp increases. Ongoing monitoring is required to determine longer-term impacts and GBM need access to appropriate and sensitive supports both during and after the COVID-19 pandemic.

Switching to Non-daily Pre-exposure Prophylaxis Among Gay and Bisexual Men in Australia: Implications for Improving Knowledge, Safety, and Uptake

GBQM require messaging about non-condom based HIV prevention strategies when they cannot access daily or event-driven PrEP.

Preferences for Current and Future PrEP Modalities Among PrEP-Experienced Gay and Bisexual Men in Australia

Alternatives to daily dosing of HIV pre-exposure prophylaxis (PrEP) are continuing to emerge. From October 2019 to March 2020, we conducted an online survey of PrEP-experienced gay and bisexual men in Australia about interest in and preference for four different PrEP modalities: daily dosing, event-driven dosing, long-acting injectable (LAI)-PrEP and subdermal PrEP implants. Using data from 1477 participants, we measured interest and preference of different modalities using multivariate logistic regression. High proportions of participants were interested in LAI-PrEP (59.7%), daily PrEP (52.0%), PrEP implants (45.3%) and event-driven PrEP (42.8%). LAI-PrEP was the most frequently selected preference (30.5%), followed by PrEP implants (26.3%), daily PrEP (21.4%) and event-driven PrEP (21.2%). Higher interest and preference for non-daily PrEP modalities were associated with being concerned about side effects and perceived difficulties with daily adherence. As novel modalities emerge, attitudes to them should be considered in public health messaging to facilitate informed decision-making.

Predictors of oral pre-exposure prophylaxis (PrEP) uptake among individuals in a HIV vaccine preparedness cohort in Masaka, Uganda

Oral pre-exposure prophylaxis (PrEP) significantly reduces human immunodeficiency virus (HIV) acquisition risk. However, data on predictors of PrEP uptake in sub-Saharan Africa are limited. We assessed predictors of PrEP uptake among HIV-uninfected high risk individuals enrolled in a HIV vaccine preparedness study in Masaka, Uganda.Between July 2018 and October 2020, we recruited adults (18-40 years) from sex work hotspots along the trans-African highway and Lake Victoria fishing communities. We collected baseline data on socio-demographics and PrEP awareness, and provided HIV counselling and testing, information on PrEP, and PrEP referrals at quarterly visits. Urine pregnancy tests (women) and data collection on sexual risk behaviour and PrEP uptake were performed every 6 months. We analysed PrEP uptake among participants who had completed 6 months of follow-up.Of the 588 cohort participants, 362 (62%) were included in this analysis. Of these, 176 (49%) were female, 181 (50%) were aged ≤24 years, 104 (29%) worked in sex work hotspots, 74 (20%) were fisher folk. Only 75 (21%) participants initiated PrEP. Predictors of PrEP uptake included having ≥6 sex partners (adjusted odds ratio [aOR] = 2.29; 95% confidence interval [CI] 1.26-4.17), engaging in transactional sex (aOR = 2.23; 95% CI 0.95-5.20), and residence in a nonfishing community (aOR = 2.40; 95% CI 1.14-5.08). The commonest reasons for not starting PrEP were pill burden (38%) and needing more time to decide (27%).PrEP uptake was low and associated with HIV risk indicators in this cohort. Interventions are needed to improve access to PrEP especially in fishing communities.

Qualitative Findings on the Impact of COVID-19 Restrictions on Australian Gay and Bisexual Men: Community Belonging and Mental Well-being

COVID-19 may threaten the already poor mental health outcomes of Australian gay and bisexual men and cut ties to important social/sexual networks and community. Qualitative research into the experiences of gay and bisexual men during COVID-19 regulations is currently sparse. We report on 489 responses to a qualitative free-text question asking Australian gay and bisexual men about the impacts of COVID-19 during April 2020. Issues pertinent to gay and bisexual men include lost ties to gay and bisexual social/sexual communities, spaces, and activities, which can reduce a sense of belonging to important sexual identity spaces, as well as significant mental well-being vulnerabilities. Reminiscing the collective response to HIV/AIDS, findings reinforce the value of gay and bisexual community organizations, spaces, and networks as supports for gay and bisexual men and emphasize the need for delivering mental health services.

Changes in Sexual Behaviour Following PrEP Initiation Among Australian Gay and Bisexual Men in Relationships: Results from a Prospective Observational Study

Few studies have examined changes in sexual behaviour following HIV pre-exposure prophylaxis (PrEP) initiation among gay, bisexual and other men who have sex with men (GBM) in relationships. In a national, online, prospective study of GBM in Australia, we compared sexual behaviours prior to and after PrEP initiation among HIV-negative and unknown-HIV-status men (recruited 2014-2017) not taking PrEP at baseline and who completed at least one six-monthly follow-up by July 2018. Among men in relationships who did not initiate PrEP (n = 339), we compared their most recent survey to their prior one, while among men in relationships who initiated PrEP (n = 81), we compared follow-ups before and after PrEP initiation. Among the 81 PrEP-initiators who were in a relationship both before and after initiation, the proportion reporting their regular partner was on PrEP increased from 8.3 to 44.4% (p < 0.001) and the proportion reporting receptive CLAIC increased from 27.2 to 44.4% (p = 0.009). Overall, men who initiated PrEP were more likely to be in a relationship with a partner on PrEP, and it appeared they started PrEP around the same time. Receptive CLAIC also became more common.

High Levels of Prevention-Effective Adherence to HIV PrEP: An Analysis of Substudy Data From the EPIC-NSW Trial

BACKGROUND

Preexposure prophylaxis (PrEP) prevents HIV infection but relies on good adherence at times of risk, termed "prevention-effective adherence." Most studies assess adherence without reference to sexual behaviur, making it challenging to determine if poor adherence coincides with HIV risk.

SETTING

We examined data from a behavioral substudy of a large-scale PrEP implementation trial in New South Wales, Australia.

METHODS

Trial participants completed optional brief quarterly surveys, reporting the number of pills taken and sexual behavior with male partners for each day of the "last full week" before each survey. Condomless sex (CLS) was defined as "higher risk" for HIV when with HIV-positive men with detectable/unknown viral loads or unknown HIV status men. Adequate PrEP protection was defined as ≥4 pills for participants assigned male sex at birth and ≥6 pills for participants assigned female sex at birth (including transgender men).

RESULTS

Of 9596 participants dispensed PrEP, 4401 completed baseline and ≥1 follow-up survey. Participants reported on 12,399 "last full weeks": 7485 weeks (60.4%) involved CLS and 2521 weeks (33.7% of CLS-weeks) involved higher risk CLS. There were 103 weeks in which participants did not have adequate PrEP protection and had higher risk CLS: 4.1% of higher-risk CLS weeks (n = 103/2521), 1.4% of all CLS weeks (n = 103/7485), and 0.8% of all observed weeks (n = 103/12,399).

CONCLUSIONS

In a large PrEP trial, prevention-effective adherence to PrEP was very high at 99%. Our findings illustrate the importance of measuring pill-taking and sexual behavior in the same period so that prevention-effective adherence can be better estimated.

A Randomized Trial of a Brief Behavioral Intervention for PrEP Uptake Among Men Who Have Sex With Men at Increased Risk for HIV Infection

BACKGROUND

The aim of this study was to evaluate the efficacy of a novel, brief 2-session behavioral intervention to promote HIV pre-exposure prophylaxis (PrEP) uptake among men who have sex with men (MSM) who are behaviorally at risk for HIV.

SETTING

A pilot randomized controlled trial was conducted at a sexually transmitted infection (STI) clinic to compare a brief motivational interviewing intervention with passive referral only for PrEP uptake.

METHODS

MSM who scored as "high risk" on the HIV Incidence Risk index for MSM was offered a brief (15-20 minutes) motivational interviewing-based intervention at the time of STI testing to address barriers to PrEP uptake, including low risk perception, stigma, side effects, and cost. The initial session was followed by a brief, telephone booster session that lasted <10 minutes. The primary outcome was attending a clinical PrEP appointment and accepting a prescription for PrEP.

RESULTS

Participants were recruited from an urban STI clinic in the United States. A total of 86 MSM who were behaviorally at risk for HIV were enrolled in the study (N = 43 intervention; N = 43 treatment-as-usual, "TAU"). Participants randomized to the intervention were significantly more likely to attend a clinical appointment and accept a prescription for PrEP, compared with treatment-as-usual (52.3% versus 27.9%, respectively; odds ratio = 3.6; 95% confidence interval: 1.5 to 8.9; P = 0.005).

CONCLUSIONS

A brief behavioral intervention focused on the initial steps in the PrEP care cascade demonstrated preliminary efficacy in promoting uptake among MSM who are behaviorally at risk for HIV.

HIV pre-exposure prophylaxis: scaling up for impact now and in the future

More than a decade after the first efficacy evidence for oral HIV pre-exposure prophylaxis (PrEP) was reported, PrEP uptake globally has been inadequate and global HIV prevention targets have been missed. Access to PrEP is still highly concentrated in a fairly small number of countries and, even within countries with widespread PrEP access, inequalities have emerged. More ambitious, high-priority global targets for PrEP uptake are required and could accelerate the HIV prevention response in a similar way to the success of the 90-90-90 testing and treatment targets. Health systems must be PrEP-friendly and allow PrEP to be prescribed in settings already attended by large numbers of HIV-negative individuals who are at risk. Several models have been advanced for the greater demedicalisation of PrEP. Individual-level barriers to PrEP uptake and persistence have been characterised, such as low awareness, low willingness to use PrEP, and the gap between self-perceived and actual HIV risk. Overcoming these barriers will require further efforts to understand and address them first. New PrEP modalities are emerging; as more options become available, we need to develop a greater understanding of the long-term patterns of PrEP use in different populations and to develop models of such use that can accommodate people alternating through periods of use and non-use, as well as switching between dosing regimens or modalities as they become available. Scaling up PrEP is crucial to achieving the UNAIDS prevention targets for 2030. Simply getting more people onto PrEP cannot be the only goal: the big-picture definition of success for PrEP programmes must be their impact on the HIV epidemic.

PrEP your team! Clinician initiation of HIV pre-exposure prophylaxis discussion at sexually transmissible infection testing and diagnosis in gay and bisexual men

HIV pre-exposure prophylaxis (PrEP) is recommended for gay and bisexual men (GBM) with recent diagnosis of rectal chlamydia (CT), rectal gonorrhoea (NG) or infectious syphilis. A retrospective medical record audit was undertaken at Canberra Sexual Health Centre (CSHC) of all GBM who met this criterion in 2019 and were thus determined to be at higher risk of acquisition of human immunodeficiency virus (HIV). Pre-exposure prophylaxis was discussed and/or commenced in 85% of GBM at higher risk of HIV. Audit results and education were provided to the team with a post-interventional audit in 2020 showing significant improvement. This audit is easily replicated and may be applicable to other settings engaged in GBM care.

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.

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.

Understanding Beliefs, Intention, and Behavior on Daily PrEP Uptake Among MSM in California and New York

Pre-exposure prophylaxis (PrEP) is an effective daily prevention medicine to reduce the risks of HIV infections. Even though the number of PrEP users has been rapidly growing in the United States since 2012, only approximately 5% of the men who have sex with men (MSM) population is currently taking PrEP. This study examined PrEP uptake among MSM using the integrative model of behavioral prediction (IMBP) as the theoretical framework. The authors conducted formative elicitation interviews and a cross-sectional survey with MSM. Among the survey respondents, half of them were PrEP takers and half were not. The path modeling results showed that attitudes and norms predicted behavioral intention, and intention predicted PrEP uptake among MSM. The results also identified the strongest attitudinal predictors and normative referents of PrEP uptake. The study offers practical implications in helping professionals and scholars to understand PrEP uptake among MSM in a theoretically grounded way.

Australian Gay and Bisexual Men Who Use Condoms, PrEP or Rarely Practise HIV Risk Reduction with Casual Sex Partners: An Analysis of National, Behavioural Surveillance Data, 2017-2018

Recent increases in the availability of pre-exposure prophylaxis (PrEP) internationally have widened the range of HIV prevention strategies available to gay and bisexual men. This paper aimed to quantify the use of different risk reduction strategies and compare characteristics of men who rarely use any strategies with those who regularly use condoms or PrEP. Using national cross-sectional data from the Gay Community Periodic Surveys in Australia, comparisons were made between regular condom users (37.1% of participants), PrEP users (50.1%), and men who infrequently used any risk reduction strategies (12.8%). The proportion of gay and bisexual men reporting infrequent use of HIV risk reduction strategies has decreased in recent years. These men reported less frequent high-risk sexual practices than PrEP users and also reported less recent HIV testing than either PrEP or condom users. Men who infrequently use HIV risk reduction strategies should be encouraged to test for HIV more regularly and to utilise prevention strategies that align with their infrequent high-risk behaviour.

Use of HIV pre-exposure prophylaxis among men who have sex with men in England: data from the AURAH2 prospective study

BACKGROUND

Since October, 2017 (and until October, 2020), pre-exposure prophylaxis (PrEP) has only been available in England, UK, through the PrEP Impact Trial, by purchasing it from some genitourinary medicine clinics, or via online sources. Here we report changes from 2013 to 2018 in PrEP and postexposure prophylaxis (PEP) awareness and use among HIV-negative gay, bisexual, and other men who have sex with men (MSM) and assess predictors of PrEP initiation.

METHODS

In the prospective cohort study Attitudes to, and Understanding of Risk of Acquisition of HIV 2 (AURAH2), MSM were recruited from three sexual health clinics in England: two in London and one in Brighton, UK. Men were eligible if they were aged 18 years or older and HIV-negative or of unknown HIV status. Participants self-completed a baseline paper questionnaire at one of the three clinics between July 30, 2013, and April 30, 2016, and were subsequently able to complete 4-monthly and annual online questionnaires, which were available between March 1, 2015, and March 31, 2018, and collected information on sociodemographics, health and wellbeing, HIV status, and sexual behaviours. PrEP and PEP use in the previous 12 months was obtained at baseline and in annual questionnaires. We assessed trends over calendar time in 3-month periods from first enrolment to the end of the study period (July-December, 2013, was counted as one period) in use of PrEP and PEP using generalised estimating equation logistic models. We used age-adjusted Poisson models to assess factors associated with PrEP initiation among participants who reported never having used PrEP at baseline.

FINDINGS

1162 men completed a baseline questionnaire, among whom the mean age was 34 years (SD 10·4), and of those with available data, 942 (82%) of 1150 were white, 1076 (94%) of 1150 were gay, and 857 (74%) of 1159 were university educated. 622 (54%) of 1162 men completed at least one follow-up online questionnaire, of whom 483 (78%) completed at least one annual questionnaire. Overall, PrEP use in the past year increased from 0% (none of 28 respondents) in July to December, 2013, to 43% (23 of 53) in January to March, 2018. The corresponding increase in PrEP use among men who reported condomless sex with two or more partners was from 0% (none of 13 respondents) to 78% (21 of 27). PEP use peaked in April to June, 2016, at 28% (41 of 147 respondents), but decreased thereafter to 8% (four of 53) in January to March, 2018. Among 460 men who had never used PrEP at baseline, predictors of initiating PrEP included age 40-44 years (incidence rate ratio [IRR] 4·25, 95% CI 1·14-15·79) and 45 years and older (3·59, 1·08-11·97) versus younger than 25 years; and after adjustment for age, recent HIV test (5·17, 1·89-14·08), condomless sex (5·01, 2·16-11·63), condomless sex with two or more partners (5·43, 2·99-9·86), group sex (1·69, 1·01-2·84), and non-injection chemsex-related drugs use (2·86, 1·67-4·91) in the past 3 months, PEP use (4·69, 2·83-7·79) in the past 12 months, and calendar year (Jan 1, 2017, to March 31, 2018 vs July 30, 2013, to Dec 31, 2015: 21·19, 9·48-47·35). Non-employment (0·35, 0·14-0·91) and unstable or no housing (vs homeowner 0·13, 0·02-0·95) were associated with reduced rates of PrEP initiation after adjustment for age. About half of PrEP was obtained via the internet, even after the PrEP Impact trial had started (11 [48%] of 23 respondents in January to March, 2018).

INTERPRETATION

PrEP awareness and use increased substantially from 2013 to 2018 among a cohort of MSM in England. Improving access to PrEP by routine commissioning by National Health Service England could increase PrEP use among all eligible MSM, but should include public health strategies to target socioeconomic and demographic disparities in knowledge and use of PrEP.

HIV Preexposure Prophylaxis Cascades to Assess Implementation in Australia: Results From Repeated, National Behavioral Surveillance of Gay and Bisexual Men, 2014-2018

BACKGROUND

HIV prevention cascades can assist in monitoring the implementation of prevention methods like preexposure prophylaxis (PrEP). We developed 2 PrEP cascades for Australia's primary HIV-affected population, gay and bisexual men.

METHODS

Data were drawn from 2 national, repeated, cross-sectional surveys (the Gay Community Periodic Surveys and PrEPARE Project). One cascade had 3 steps, and the other had 7 steps. Trends over time were assessed using logistic regression. For the most recent year, we identified the biggest drop between steps in each cascade and compared the characteristics of men between the 2 steps using multivariate logistic regression.

RESULTS

Thirty-nine thousand six hundred and seventy non-HIV-positive men participated in the Periodic Surveys during 2014-2018. PrEP eligibility increased from 28.1% (1901/6762) in 2014 to 37.3% (2935/7878) in 2018 (P < 0.001), awareness increased from 29.6% (563/1901) to 87.1% (2555/2935; P < 0.001), and PrEP use increased from 3.7% (21/563) to 45.2% (1155/2555; P < 0.001). Of 1038 non-HIV-positive men in the PrEPARE Project in 2017, 54.2% (n = 563) were eligible for PrEP, 97.2% (547/563) were aware, 67.6% (370/547) were willing to use PrEP, 73.5% (272/370) had discussed PrEP with a doctor, 78.3% (213/272) were using PrEP, 97.2% (207/213) had recently tested, and 75.8% (157/207) reported reduced HIV concern and increased pleasure because of PrEP. The break point analyses indicated that PrEP coverage was affected by geographical availability, education level, employment, and willingness to use PrEP.

CONCLUSIONS

PrEP eligibility, awareness, and use have rapidly increased among Australian gay and bisexual men. The cascades identify disparities in uptake by eligible men as a result of socioeconomic factors and PrEP's acceptability.

Increases in HIV Testing Frequency in Australian Gay and Bisexual Men are Concentrated Among PrEP Users: An Analysis of Australian Behavioural Surveillance Data, 2013-2018

Increasing HIV testing frequency in gay and bisexual men (GBM) is critical to reducing the time between HIV infection and diagnosis. Using anonymous national behavioural surveillance data (2013-2018) from 43,753 surveys of Australian GBM, we examined HIV testing frequency trends and factors differentiating PrEP-users, non-PrEP-users reporting two or more tests in the previous year, and non-PrEP-users reporting less frequent testing. The proportion tested at least annually increased from 64.4% in 2013 to 70.8% in 2018 (p-trend < 0.001), and from 73.9% to 84.6% among the 51.6% of men classified as higher-risk. Among higher-risk men, having two or more tests in the previous year increased from 48.0% to 69.3% (p-trend < 0.001). Among higher-risk non-PrEP-users, it increased from 47.2% to 54.8% (p-trend < 0.001), however, there was a decrease since 2016 (p-trend < 0.001). Among PrEP-users, it increased from 82.1% in 2013 to 97.3% in 2018 (p-trend < 0.001). Non-PrEP-using higher-risk men having less frequent tests reported lower risk than PrEP-users and non-PrEP-using men reporting two or more tests in the previous year. However, recent risk behaviour was not uncommon: nearly half reported condomless sex; one-fifth reported receptive condomless sex with ejaculation; over half reported group sex; one-quarter used drugs for the purposes of sex; and one-fifth had more than ten sex partners. Efforts are needed to encourage frequent testing and PrEP use among non-PrEP-users who are at higher-risk.

Assessing the HIV Prevention Needs of Young Gay and Bisexual Men in the PrEP Era: An Analysis of Trends in Australian Behavioural Surveillance, 2014-2018

Data from repeated, national behavioural HIV surveillance was used to identify similarities and differences between young gay and bisexual men (YGBM) aged 16-24 (n = 1608) and older GBM aged 25-49 (n = 6266), in order to quantify risks and identify gaps in HIV prevention. Trend analyses from 2014 to 2018 are also reported. While there were similar rates of condomless anal intercourse with casual partners in both age groups, YGBM had lower rates of HIV testing and PrEP use but also fewer male partners. Our results suggest most YGBM have lower HIV risk than older GBM but a minority merit enhanced testing and prevention efforts.

Use of HIV Pre-exposure Prophylaxis (PrEP) Associated With Lower HIV Anxiety Among Gay and Bisexual Men in Australia Who Are at High Risk of HIV Infection: Results From the Flux Study

BACKGROUND

Many gay and bisexual men (GBM) experience HIV anxiety, particularly around condomless anal intercourse. HIV pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy that may reduce HIV anxiety among GBM.

METHODS

The Following Lives Undergoing Change (Flux) Study is a national, online, open-prospective observational study of licit and illicit drug use among GBM in Australia. In 2018, participants responded to newly included items regarding anxiety about HIV transmission. Stratifying GBM as high or low risk as determined by the Australian PrEP Guidelines, we assess whether PrEP use is associated with lower levels of HIV anxiety. Multivariate logistic regression was used to compare factors associated with PrEP use among GBM at high risk (PrEP-eligible) and low risk (PrEP-ineligible) of HIV infection. Results are reported as adjusted odds ratios and corresponding 95% confidence intervals.

RESULTS

Among 1547 men, the mean age was 37.1 years (SD 13.1). Men aged 25 years or younger had higher HIV anxiety scores than older men. Among PrEP-eligible men, men who use PrEP reported lower levels of HIV anxiety (adjusted odds ratio = 0.92; 95% confidence interval = 0.87 to 0.99; P < 0.001). No differences were observed on HIV anxiety among PrEP-ineligible men.

CONCLUSIONS

Among PrEP-eligible men, PrEP use was independently associated with lower levels of HIV anxiety. In addition to avoiding HIV infection, PrEP use may help reduce anxiety among men at risk of HIV. This feature of PrEP could be promoted as part of demand creation initiatives to increase PrEP uptake.

Characteristics of gay and bisexual men who rarely use HIV risk reduction strategies during condomless anal intercourse: Results from the FLUX national online cohort study

Purpose

To understand the characteristics of a minority of Australian gay and bisexual men (GBM) who, despite an increase in the number and availability of HIV risk reduction strategies, do not consistently use a strategy to protect themselves from HIV.

Methods

This analysis is based on data from 2,920 participants in a national, online, prospective observational cohort study. GBM who never or rarely used HIV risk reduction strategies (NRR) were compared with two groups using multivariate logistic regression: i) GBM using pre-exposure prophylaxis (PrEP) and ii) GBM frequently using risk reduction strategies (FRR) other than PrEP.

Results

Compared to PrEP users, NRR men were younger (p<0.0001), less socially engaged with gay men (p<0.0001) and less likely to have completed a postgraduate (p<0.05) or undergraduate degree (p<0.05). They were also less likely to have recently used amyl nitrite (p<0.05), erectile dysfunction medication (p<0.05) and cocaine (p<0.05) in the previous 6 months. Compared with FRR men, NRR men were less likely to have completed a postgraduate (p<0.0001) or undergraduate degree (p<0.05), scored higher on the sexual sensation-seeking scale (p<0.0001) and were more likely to identify as versatile (p<0.05), a bottom (p<0.05) or very much a bottom (p<0.05) during anal sex.

Conclusions

NRR men were largely similar to other Australian GBM. However, our analysis suggests it may be appropriate to focus HIV prevention interventions on younger, less socially engaged and less educated GBM, as well as men who prefer receptive anal intercourse to promote the use of effective HIV risk reduction strategies.

Gay Men's Relationship Agreements in the Era of Pre-exposure Prophylaxis: An Analysis of Australian Behavioural Surveillance Data

Using repeated, cross-sectional behavioural surveillance data from Australia, we assessed trends in relationship agreements and casual sex among HIV-negative and untested gay and bisexual men who had regular partners during 2013-2018. We conducted three analyses: (i) trends in relationship agreements and casual sex over time; (ii) bivariate comparisons of PrEP users and non-PrEP-users to identify factors associated with PrEP use; and (iii) multivariate logistic regression to identify factors independently associated with PrEP use. The analysis of trends over time included 21,593 men, from which a sub-sample (n = 3764) was used to compare PrEP users and non-PrEP-users. We found a large increase in agreements that allowed condomless sex with casual partners, particularly by PrEP users in relationships (nearly 40% of whom had such an agreement). A further 34% of PrEP users reported having casual condomless sex without an agreement that permitted that behaviour, while 13% of non-PrEP-users also reported condomless sex with casual partners without an agreement. PrEP use was independently associated with having agreements permitting condomless sex with casual partners, recent condomless sex with casual partners, having greater numbers of male partners, recent post-exposure prophylaxis use, having an HIV-positive regular male partner, and recent condomless sex with regular male partners. Our findings show a shift away from relationship agreements in which condomless sex was only sanctioned between regular partners.

The impact of self-selection based on HIV risk on the cost-effectiveness of preexposure prophylaxis in South Africa

OBJECTIVES

We explored the impact and cost-effectiveness of preexposure prophylaxis (PrEP) provision to different populations in South Africa, with and without effective self-selection by individuals at highest risk of contracting HIV (through concurrent partnerships and/or commercial sex).

DESIGN AND METHODS

We used a previously developed HIV transmission model to analyse the epidemiological impact of PrEP provision to adolescents, young adults, pregnant women, female sex workers (FSWs) and (MSM), and data from South African PrEP programmes to estimate the cost and cost-effectiveness of PrEP (cost in 2019 USD per HIV infection averted over 20 years, 2019, 38). PrEP uptake followed data from early implementation sites, scaled-up linearly over 3 years, with target coverage set to 18% for adolescents, young adults and pregnant women, 30% for FSW and 54% for MSM.

RESULTS

The annual cost of PrEP provision ranges between $75 and $134 per person. PrEP provision adolescents and young adults, regardless of risk behaviour, will each avert 3.2--4.8% of HIV infections over 20 years; provision to high-risk individuals only has similar impact at lower total cost. The incremental cost per HIV infection averted is lower in high-risk vs. all-risk sub-populations within female adolescents ($507 vs. $4537), male adolescents ($2108 vs. $5637), young women ($1592 vs. $10 323) and young men ($2605 vs. $7715), becoming cost saving within 20 years for high-risk adolescents, young women, MSM and FSWs.

CONCLUSION

PrEP is an expensive prevention intervention but uptake by those at the highest risk of HIV infection will make it more cost-effective, and cost-saving after 14-18 years.
