Factors associated with experiencing stigma, discrimination, and negative health care treatment among people who inject drugs.

INTRODUCTION: Stigma has negative consequences for the health of people who inject drugs and people living with hepatitis C virus (HCV). This study evaluated factors associated with stigma related to injecting drug use (IDU) or HCV and those associated with being treated negatively by health workers. METHODS: ETHOS Engage is an observational cohort study of people who inject drugs attending drug treatment clinics and needle and syringe programs in Australia. Participants completed a questionnaire including IDU- and HCV-related stigma, and negative treatment by health workers. Logistic regression was used to identify factors associated with experiencing stigma and negative treatment in a cross-sectional sample. RESULTS: Of 1,211 participants, 31% were women, 64% had injected drugs in the previous month, and 65% had been diagnosed with HCV. IDU-related stigma was reported by 57% of participants and was associated with being a woman, higher than Year 10 education, homelessness, opioid agonist treatment, recent injecting, overdose history, hospitalisation for drug use, and unknown HCV status. HCV-related stigma was reported by 34% of participants diagnosed with HCV and was associated with being a woman, homelessness, receptive needle/syringe sharing, arrest for drug use/possession, and recent HCV testing. Negative treatment from health workers was reported by 45% of participants and was associated with being a woman, receptive needle/syringe sharing, hospitalisation for drug use, and arrest for drug use/possession. DISCUSSION AND CONCLUSIONS: Results highlight important intersections and disparities in stigmatising experiences among people who inject drugs. Considering these intersections can assist health services provide more inclusive care.

Informed, but uncertain: managing transmission risk and isolation in the 2022 mpox outbreak among gay and bisexual men in Australia.

In 2022, a global outbreak of mpox (formerly 'monkeypox') emerged in non-endemic countries, including Australia, predominantly affecting gay, bisexual and other men who have sex with men. Public health advice on transmission and isolation emerged rapidly from different sources, sometimes conflicting and producing uncertainty. Using the concept of 'counterpublic health', which acknowledges the incorporation of official science and experiences of affected communities into embodied practice, this paper investigates how people affected by mpox in Australia managed risk of transmission and navigated self-isolation. In-depth interviews were conducted with 16 people: 13 people diagnosed with mpox and three close contacts. All participants were cisgender gay and bisexual men living in Australia. Participants thought critically about public health advice, often finding it restrictive and unresponsive to the needs of people with mpox. Participants' decisions about reducing mpox risk and isolating often drew on experiences with other infections (i.e. HIV; COVID-19) and were made collaboratively with the people closest to them (e.g. partners, friends, family) to sustain relationships. Future public health responses to infectious disease outbreaks would benefit from identifying more opportunities to formalise and embed mechanisms to obtain feedback from affected communities so as to inform responses.

Factors associated with hepatitis B knowledge among people of Vietnamese ethnicity in Australia.

Despite high hepatitis B (HBV) prevalence among people of Vietnamese ethnicity in Australia and elsewhere, there is limited research on levels of HBV knowledge and factors associated with such knowledge. The aim of this study was to examine HBV knowledge and associated demographic and attitudinal factors among people of Vietnamese ethnicity in Australia. People of Vietnamese ethnicity (n = 966) were recruited through community events and social media groups to complete online surveys measuring HBV knowledge, attitudes towards HBV, levels of mistrust in Western medicine, and demographic characteristics. Findings of this study indicate that levels of knowledge are mixed, with gaps in knowledge related to transmission and treatment of the virus. Those with greater knowledge of HBV tended to be older, have higher levels of formal education, have been tested for HBV, and know someone living with HBV. Those with lower levels of knowledge tended to have more negative attitudes towards the virus and greater levels of mistrust in Western medicine. Given that health literacy is connected to effective communication from health providers, we suggest that there is a need for the development of health promotion and education resources targeted at people of Vietnamese ethnicity and translated into Vietnamese. We propose that such resources be developed in consultation with Vietnamese communities and health providers to ensure that they are culturally appropriate and sensitive to people of Vietnamese ethnicity living in Australia.

Stigma, and factors associated with experiencing stigma, while visiting health-care services among samples of people who use illegal drugs in Australia.

INTRODUCTION: People who inject drugs experience stigma across multiple settings, including when accessing health-care services, however, comparatively little is known about experiences of stigma towards other groups of people who use illegal drugs. This paper examines experience of, and factors associated with, stigma among two samples of people who use illegal drugs when visiting both specialist alcohol and other drug (AOD) and general health-care services. METHODS: Australians who regularly (i.e., ≥monthly) inject drugs (n = 879; illicit drug reporting system [IDRS]) or use ecstasy and/or other illegal stimulants (n = 700; ecstasy and related drugs reporting system [EDRS]) were surveyed between April and July 2022 about past 6-month experience of stigma in the above services. Multi-variable regression analyses were performed to determine the socio-demographic, drug use and health factors associated with stigma. RESULTS: Experiences of stigma in general health-care services were more common among IDRS (40%) than EDRS (24%; p < 0.001) participants, however, experiences were comparable in specialist AOD health-care settings (22% and 20%, respectively; p = 0.687). Gender identity and experiencing high psychological distress were associated with experiencing stigma across both samples. Past-year overdose was associated with experiencing stigma among the IDRS sample, while unstable housing and incomplete high school education were associated with experiencing stigma in the EDRS sample. DISCUSSION AND CONCLUSIONS: Experiences of stigma when accessing health-care services are relatively common across different populations of people who use illegal drugs. Our findings highlight the multiple and intersecting dimensions of stigma and provide further support for recent calls for a universal precautions approach to stigma in health care.

Hepatitis B screening and knowledge among Chinese and Vietnamese students in Australia.

Research has shown that there are significant gaps in hepatitis B knowledge among migrant communities who are at risk of hepatitis B, such as Chinese and Vietnamese communities. Many students studying within Australia come from countries with high prevalence of hepatitis B. However, there is very little research examining hepatitis B knowledge, screening, or vaccination among university students in Australia or worldwide. The aim of this paper was to measure both levels of and demographic differences in hepatitis B screening and knowledge among Chinese and Vietnamese students in Australia. Online surveys were completed by 112 Chinese- and 95 Vietnamese-identifying students in Australia, measuring knowledge of hepatitis B, engagement in screening and vaccination, and demographic characteristics. Results show that although engagement in screening and vaccination for hepatitis B was high, there were significant gaps in knowledge around transmission of hepatitis B. There were also some key demographic differences in screening and knowledge. For instance, those born in Australia were more likely to have been screened compared to those born Mainland China, Hong Kong, or Vietnam. Chinese students born in Australia had lower levels of knowledge compared to those born in Mainland China or Hong Kong. Among both samples, knowing someone living with hepatitis B was associated with higher levels of knowledge. Findings underscore the need for education-based interventions to address the significant gaps that exist in knowledge around hepatitis B, with a specific need for culturally appropriate resources in a range of languages to cater to the diverse communities who may be at risk of hepatitis B.

Mpox Illness Narratives: Stigmatising Care and Recovery During and After an Emergency Outbreak.

In May 2022, a global outbreak of mpox (formerly monkeypox virus) affected thousands of mainly gay and bisexual men. Mpox is usually a time-limited illness that can involve fever, pain, and skin lesions, but may require hospitalisation. There is scant research into the firsthand experiences of people affected by mpox, including experiences of symptoms, healthcare, and recovery. This study considers the different illness narratives of people who experienced mpox in Australia in 2022. In-depth interviews and 6-month follow-up interviews were conducted with 16 people, including 13 people diagnosed with mpox and three close contacts. All participants were cisgender gay or bisexual men living in Australia. Participants' accounts described minor to severe periods of sickness, negative and stigmatising experiences engaging with healthcare, and some participants experienced long-term effects on their sexual well-being and complications from mpox. The emergency outbreak context meant that mpox was highly distressing, making it difficult to manage and producing varying forms of disruption to everyday life. Mpox was narrated as disruptive in different ways: as a minor interruption to holiday plans, a prolonged period of poor health, or a biographically disruptive event prompting a re-evaluation of sexual values and health. This analysis demonstrates that an unfamiliar emergent disease outbreak related to sexual practices and sociality can reconfigure personal life and sexual well-being, suggesting a need to focus on providing quality patient care in outbreaks of mpox and other infectious diseases.

Differences in stigma reduction related to injection drug use between people expressing conservative, moderate and progressive values following an online intervention.

INTRODUCTION: Contact interventions have shown short-term effectiveness in reducing stigmatising attitudes and behaviours of the public towards marginalised population groups, including people who inject drugs. We theorised that the effectiveness of an intervention differs according to peoples' underlying social values and undertook a study to test this. METHODS: We recruited participants from the Australian public by social media and measured their attitudes, desire to maintain personal distance, and support for structural stigma towards people who inject drugs before and after a brief online video intervention (n = 314). We divided participants into tertile groups according to their responses to a conservatism scale and compared group differences in post-intervention stigma scores (n = 242-244), controlling for pre-intervention scores and demographic variables. RESULTS: Adjusting for baseline levels, the post-intervention scores in all measures showed significant improvement but scores of the moderate group were consistently most improved. Stigmatising attitudes in the moderate group were significantly reduced when compared with the conservative and progressive groups. However, reductions in desire for personal distance and support for structural stigma did not significantly differ by conservatism group. DISCUSSION AND CONCLUSIONS: A brief online contact intervention showed immediate effectiveness in reducing stigma towards people who inject drugs. As people with moderate values were found to be more amenable to changing their perspectives, audience social values may need consideration when designing and evaluating stigma interventions. More research is needed to understand how to influence people with more conservative values, and how to increase public support for policies and practices that reduce stigma.

Assessing HIV risk and the social and behavioural characteristics of gay and bisexual men who have recently migrated to Australia: an analysis of national, behavioural surveillance data 2019-2021.

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.

Experiences of stigma and subsequent reduced access to health care among women who inject drugs.

INTRODUCTION: Research into stigma and injecting drug use has typically involved predominantly male participants, with limited research about the unique experience of women who inject drugs. METHODS: This study used survey methods to assess reduced access to health care due to stigma among a sample of women who inject drugs. Women (n = 232) completed a survey as part of a broader national study of people who inject drugs. RESULTS: Only 46 (19.9%) women reported that they had not experienced any injecting drug use-related stigma in the past year and most commonly noted 'sometimes' experiencing injecting-related stigma (36.8%) with more than 75% of women reporting that health workers had treated them negatively because of their injecting drug use. Most women undertook strategies to prevent experiencing stigma, such as not disclosing drug use to a health worker (81.3%), not attending follow-up appointments (76.7%) and delaying accessing health care (76.8%). Women with lower levels of personal wellbeing, who had experienced poorer treatment by health workers, had engaged in greater past month injecting, were employed and identified as lesbian, gay, bisexual, transgender or queer (LGBTQ) reported more reduced access to health care. DISCUSSION AND CONCLUSIONS: Stigma has concerning health care implications for women who inject drugs and this research highlights the importance of understanding the impact of stigma in impeding health care access. Public health interventions should focus on addressing the systemic factors that reduce health care access for women who inject and take account of the impact of stigma in diminishing the quality and accessibility of health care for this group.

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.

Trends in Testing and Self-Reported Diagnoses of Sexually Transmitted Infections in Gay and Bisexual Men in Australia, 2017 to 2021: Analysis of National Behavioral Surveillance Surveys.

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.

Variations in HIV Prevention Coverage in Subpopulations of Australian Gay and Bisexual Men, 2017-2021: Implications for Reducing Inequities in the Combination Prevention Era.

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.

RESUMEN: Utilizando datos repetidos de vigilancia conductual recopilados de hombres homosexuales y bisexuales (GBM) en toda Australia, evaluamos las tendencias en la cobertura de la prevención del VIH (el nivel de "sexo seguro" logrado en la población mediante el uso de métodos de prevención eficaces, incluyendo condones, Profilaxis de Pre-Exposición al VIH [PrEP] y tener una carga viral indetectable). Estratificamos estas tendencias por edad, país de nacimiento/tiempo desde la llegada al país, identidad sexual y proporción de residentes homosexuales en el suburbio del participante. Entre 25.865 participantes con parejas masculinas ocasionales, la cobertura de prevención del VIH aumentó del 69,8% en 2017 al 75,2% en 2021, cifra inferior al objetivo de ONUSIDA del 95%. Se lograron niveles más altos de cobertura entre GBM de mayor edad (≥45 años), inmigrantes no llegados recientemente y en suburbios con ≥10% de residentes homosexuales. Los niveles más bajos de cobertura de prevención (y los niveles más altos de riesgo de VIH) se registraron entre los GBM más jóvenes (<25 años) y los participantes bisexuales y con otras identidades. Los GBM más jóvenes, recién llegados y bisexuales fueron los más propensos a usar condones, mientras que el uso de PrEP se concentró entre hombres homosexuales, de 25 a 44 años, y en los suburbios con más residentes homosexuales. El uso de carga viral indetectable fue más común entre los participantes de ≥45 años. Nuestro análisis demuestra que se puede lograr una alta cobertura de prevención del VIH mediante una combinación del uso de condón, uso de PrEP y carga viral indetectable, o enfatizando el uso de PrEP. En el contexto australiano, se debe dar prioridad a los GBM más jóvenes, bisexuales y con otras identidades para mejorar el acceso a métodos eficaces de prevención del VIH. Alentamos a otras jurisdicciones a evaluar el nivel de cobertura logrado mediante la prevención combinada y las variaciones en la adopción.

Mpox (monkeypox) knowledge, concern, willingness to change behaviour, and seek vaccination: results of a national cross-sectional survey.

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.

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

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

National Surveillance of Home-Based HIV Testing Among Australian Gay and Bisexual Men, 2018-2020: Uptake After Commercial Availability of HIV Self-Tests.

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.

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.

Reducing stigma towards people living with HIV and people who inject drugs using social norms theory: An online study with Australian health care workers.

BACKGROUND: Despite extensive evidence regarding the negative effects of stigma experienced by people living with HIV (PLHIV) and people who inject drugs within health care settings, comparatively little evidence exists regarding the effectiveness of initiatives to reduce this stigma. METHOD: This study developed and assessed brief online interventions based on social norms theory with a sample of Australian health care workers (n=653). Participants were randomly allocated to either 1) HIV intervention group, or 2) injecting drug use intervention group. They completed baseline measures of their attitudes towards either PLHIV or people who inject drugs, matching measures of their perceptions of their colleagues' attitudes, plus a series of items reflecting behavioural intentions and agreement with stigmatising behaviour towards PLHIV or people who inject drugs. Participants were presented with a social norms video before completing the measures again. RESULTS: At baseline, participants' agreement with stigmatising behaviour was correlated with their perceptions of how many of their colleagues would agree. After watching the video, participants reported more positive perceptions of their colleagues' attitudes towards PLHIV and people who inject drugs, as well as more positive personal attitudes towards people who inject drugs. Changes in perceptions of colleagues' support for stigmatising behaviour independently predicted changes in participants' personal agreement with that behaviour. CONCLUSION: Findings suggest that interventions based on social norms theory that address health care workers' perceptions of their colleagues' attitudes can play an important role in contributing to broader initiatives to reduce stigma in health care settings.

Changing Characteristics of HIV-Positive Gay and Bisexual Men's Relationships in the Era of Biomedical Prevention.

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.

Knowledge of Australia's My Health Record and factors associated with opting out: Results from a national survey of the Australian general population and communities affected by HIV and sexually transmissible infections.

My Health Record is Australia's national, digital, personal health record system. All Australians have a record in the system unless they choose to opt out of it. Concerns about privacy, security and unwanted sharing of data, particularly in marginalised populations, may impede its use. We conducted a national, online survey of Australians' attitudes to digital health in April-June 2020. The sample (N = 2,240) was recruited from the general population and four priority populations affected by HIV and other sexually transmissible infections: gay and bisexual men, people living with HIV, sex workers, and trans and gender diverse people. This analysis assesses factors associated with greater knowledge of My Health Record and the likelihood of opting out of the system. Due to increased concerns about data privacy and misuse, we hypothesised that priority population members would know more about and be more likely to opt out of the system. We found that most of the sample (71.2%) knew little about My Health Record and 29.4% had opted out of the system. Greater knowledge of My Health Record was associated with younger age, having a university degree, having one or more health conditions, and being trans or gender diverse. Being a student, unemployed, receiving government benefits, or having poor self-reported health, were associated with less knowledge. Opting out of My Health Record was associated with having a university degree, one or more health conditions, and being a priority population member. The likelihood of opting out was lower among people born overseas, residents of Queensland, and people who were students, unemployed, or receiving government benefits. We recommend additional investment in community-based education to address people's concerns about My Health Record and support people to use the system without compromising their health care, privacy, or security. Opting out may be a legitimate choice for people who perceive more risks than benefits from the system.

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

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