Trends in late and advanced HIV diagnoses among migrants in Australia; implications for progress on Fast-Track targets: A retrospective observational study

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.

Men of refugee and migrant backgrounds in Australia: a scoping review of sexual and reproductive health research

Australia's National Men's Health Strategy 2020-2030 identifies refugee and migrant men from culturally and lingustically diverse backgrounds as priority groups for sexual and reproductive health (SRH) interventions. The paucity of SRH research focusing on refugee and migrant men is a significant gap to advance men's health and policy. Hence, this review aimed to synthesise the available evidence on refugee and migrant men's SRH needs, understandingsand experiences of accessing services after resettlement in Australia. A systematic search of peer reviewed literature in PubMed, Scopus, and PsyInfo was made. A World Health Organization framework for operationalising sexual health and its relationship with reproductive health was used to map the identified studies. The socio-ecological framework was applied to thematically synthesise data extracted from individual studies and identify factors that influence the SRH of refugee and migrant men. We included 38 papers in the review. The majority of sexual health studies (16) were about sexually transmitted infections (STIs), mainly HIV (12), followed by sexual health education and information (5) and sexual functioning (3). Reproductive health studies focused on contraceptive counselling and provision (3), antenatal, intrapartum and postnatal care (1) and safe abortion care (1). Several factors influenced refugee and migrant men's SRH, including a lack of access to SRH information, language barriers and stigma. We found that SRH literature on refugee and migrant men focuses on STIs, meaning other areas of SRH are poorly understood. We identified key gaps in research on experiences of, and access to, comprehensive SRH care.

Real-world data in late presentation of HIV infection in Suzhou, China: Results from four consecutive cross-sectional surveys, 2017-2020

Objectives

This study aimed to examine the real prevalence of late presentation of HIV infection and to identify factors associated with late HIV presentation among patients with newly diagnosed HIV/AIDS in Suzhou, China.

Methods

Patients with newly diagnosed HIV/AIDS who registered in national AIDS surveillance system from 2017 to 2020 were included in this study. Late presentation (LP) of HIV infection was defined as HIV diagnosis with a CD4 count < 350 cells/μL or an AIDS-defining event. Multivariable logistic regression analyses were used to identify factors associated with LP.

Results

A total of 2,300 patients were enrolled. 1,325 were classified as late presenters, showing a high percentage of 57.6% (95% CI: 54.5-60.7%) and a rise (P = 0.004) over the four-year period. Patients with newly diagnosed HIV/AIDS who were older than 24 years of age (aOR = 1.549, P = 0.001 for 25-39 years; aOR = 2.389, P < 0.001 for 40 years and older), were Suzhou registered residents (aOR = 1.259, P = 0.026), and were from inpatient and outpatient (aOR = 1.935, P < 0.001) were more likely to be late presentation.

Conclusions

This study showed a high percentage and a rise of late presentation of HIV infection among patients with newly diagnosed HIV/AIDS in Suzhou, China, which is a challenge for future prevention and control of AIDS. Targeted measures should be urgently implemented to reduce late HIV diagnosis.

"It was protected, except, it wasn't [with] a condom": a mixed-methods study of BBVs/STIs protective practices among International University Students in Sydney, Australia

BACKGROUND

A number of previous sex-related studies among international students in Australia and other Western societies may be limited by conflating students from conservative and non-conservative sexual backgrounds. Such conflation leads to situations where nuances and complexities around sex-related experiences are lost or, at most, tangentially investigated. To address this research problem, this study used a mixed-methods design to examine protective practices against blood-borne viruses and sexually transmissible infections (BBVs/STIs) among Sydney-based East Asian and sub-Saharan African international students.

METHODS

This mixed-methods study generated quantitative data using anonymous online survey (n = 149), and qualitative data through in-depth interviews (n = 20). The main recruitment strategy involved advertising the study through paper and electronic flyers. Quantitative data were analysed using logistic regression, while interviews data were analysed using reflexive thematic analysis.

RESULTS

Self-reported BBVs/STIs protective practices in the last 12 months include abstinence (28.7%), consistent condom use (19.9%), occasional condom use (18.7%), single partner fidelity (25.1%), other strategies (1.8%), and nothing (5.8%). Further, findings from the bivariate analysis showed higher BBVs/STIs prevention knowledge, lower acculturation into Australian sexual culture, greater access to sexual health information, less conservative sexual norms, greater emotional social support and older age were significantly associated with increased protective practices. Variables significant at bivariate level were entered into a logistic regression. The model was statistically significant, (X²(6) = 31.33, p < 0.01) and explained 33.1% of the variance in BBVs/STIs protective practices. However, only acculturation to sexual norms in Australia (OR = 0.883, 95% CI = 0.820-0.952) was found to be independent predictor of BBVs/STIs protective practices. The results of the study based on the quantitative data, indicated condom use (consistent and occasional) was the most reported BBVs/STIs protective behaviour among sexually active participants. Therefore, interviews data was used to explore condom-use motives and practices. The interviews results showed participants primary concern as regards condom use was around pregnancy and not BBVs/STIs. Thus, some participants described safe sex largely as contraception, with BBVs/STIs constituting a secondary concern or no concern at all.

CONCLUSIONS

Based on the results of this study, tailored sexual health interventions for international students; which incorporate strategies for modifying perceived sexual norms in Australia, are advocated. In addition, this study recommends sexual health interventions that promote dual protection of condoms for both contraception and BBVs/STIs.

Experiences of recently HIV-diagnosed gay and bisexual migrants in Australia: Implications for sexual health programmes and health promotion

Gay and bisexual migrants from low- and middle-income countries living in high-income countries are disproportionately diagnosed with HIV. Most research focuses on preventing HIV acquisition among HIV-negative migrant gay and bisexual men (GBM). This study is uniquely positioned to report on migrant GBM's experiences and needs at and after an HIV diagnosis. Semi-structured interviews were conducted with 24 migrant GBM diagnosed at sexual health clinics in Australia from 2017 onwards. Interviews were analysed using a codebook thematic analysis. Due to the stigma of HIV and homosexuality in their countries of origin, about half of participants had poor HIV knowledge prior to diagnosis. Absorbing diagnosis information was consequently difficult, and feelings of shame, hopelessness, lost sexual opportunities and infectiousness were common. However, many were thankful for the comprehensive clinical support they received and believed that over time life would 'normalise' with sustained undetectable viral load. None reported that their clinician stigmatised them, but the anticipation of stigma nonetheless infused their experiences after diagnosis. Many were selective about HIV disclosure, and some mentioned that clinic systems posed a risk to confidentiality. Non-permanent residents were concerned about the impacts of HIV status on future visa applications. We recommend that newly HIV-diagnosed migrant GBM receive referral to legal and culturally appropriate migration services to help absorb what a diagnosis might mean for their health and visa status. We also recommend sexual health clinics continue to assess confidentiality in their systems. Health promotion initiatives should highlight to migrant GBM that high-HIV caseload sexual health clinicians provide confidential and comprehensive care.

Preferences for HIV Testing Services and HIV Self-Testing Distribution Among Migrant Gay, Bisexual, and Other Men Who Have Sex With Men in Australia

Background

In Australia, undiagnosed HIV rates are much higher among migrant gay, bisexual, or other men who have sex with men (GBMSM) than Australian-born GBMSM. HIV self-testing is a promising tool to overcome barriers to HIV testing and improve HIV testing uptake among migrant GBMSM. We compared the preferences for HIV testing services, including HIV self-testing, among migrant and Australian-born GBMSM.

Methods

Preferences were assessed via two discrete choice experiments (DCEs). Participants were recruited between December 2017 and January 2018 using online and offline advertising and randomly assigned to complete one of two online DCE surveys. Migrant GBMSM were classified as being born in a country with a reciprocal healthcare agreement (RHCA) with Australia (providing free or subsided health care) or not. Latent class analysis and mixed logit models were used to explore heterogeneity in preferences.

Findings

We recruited 1,606 GBMSM, including 583 migrant men of whom 419 (72%) were born in non-RHCA countries. Most participants preferred a free or cheap oral test with higher accuracy and a shorter window period to facilitate early detection of infections. Cost was more important for men born in non-RHCA countries than for men from RHCA countries or Australia. All groups preferred accessing kits through online distributers or off the shelf purchasing from pharmacies. Men born in RHCA countries least preferred accessing HIV self-testing kits from a medical clinic, while more than half of men from non-RHCA countries most preferred sourcing kits from a clinic. Sex-on-premises venues were the least preferred location to access test kits among all groups. In addition, two latent class analyses explored heterogeneity in preferences among men from non-RHCA countries and we found four latent classes for HIV testing services and two latent classes for HIVST distribution.

Interpretation

Our findings emphasise the need for high-performing and low-cost HIV self-testing kits that are accessible from a variety of distribution points as a component of Australia's HIV response, especially for those who do not have access to free or subsidised health care in Australia.

The impact of sources of stigma on health care avoidance among gay and bisexual men in Australia

Stigma has a negative impact on health and wellbeing for gay and bisexual men (GBM). There is little research which assesses whether stigma from various sources affects access to different health care services. Further, those people who pay more attention to their stigmatised condition may be more likely to avoid health services. This study aimed to assess the association between sources of stigma and health care avoidance amongst a sample of GBM, as well as the role of heightened stigma sensitivity. The sample consisted of 1116 GBM in Australia who completed an online survey. Findings illustrate that those reporting any stigma were more likely to avoid health care services, while avoiding different types of health care was related to the source of the stigma. Greater stigma sensitivity was associated with avoidance of all health care services. GBM may come to health services with complex and potentially recurrent experiences of stigma. Working on the assumption that clients have a history of negative experiences in health care will increase the ability of services to work sensitively with GBM clients and ensure that access to health care amongst this group is increased.

Phylogenetic clustering networks among heterosexual migrants with new HIV diagnoses post-migration in Australia

Background

It is estimated that approximately half of new HIV diagnoses among heterosexual migrants in Victoria, Australia, were acquired post-migration. We investigated the characteristics of phylogenetic clusters in notified cases of HIV among heterosexual migrants.

Methods

Partial HIV pol sequences obtained from routine clinical genotype tests were linked to Victorian HIV notifications with the following exposures listed on the notification form: heterosexual sexual contact, injecting drug use, bisexual sexual contact, male-to male sexual contact or heterosexual sexual contact in combination with injecting drug use, unknown exposure. Those with heterosexual sexual contact as the only exposure were the focus of this study, with the other exposures included to better understand transmission networks. Additional reference sequences were extracted from the Los Alamos database. Maximum likelihood methods were used to infer the phylogeny and the robustness of the resulting tree was assessed using bootstrap analysis. Phylogenetic clusters were defined on the basis of bootstrap and genetic distance.

Results

HIV pol sequences were available for 332 of 445 HIV notifications attributed to only heterosexual sexual contact in Victoria from 2005–2014. Forty-three phylogenetic clusters containing at least one heterosexual migrant were detected, 30 (70%) of which were pairs. The characteristics of these phylogenetic clusters varied considerably by cluster size. Pairs were more likely to be composed of people living with HIV from a single country of birth (p = 0.032). Larger clusters (n≥3) were more likely to contain people born in Australian/New Zealand (p = 0.002), migrants from more than one country of birth (p = 0.013) and viral subtype-B, the most common subtype in Australia (p = 0.006). Pairs were significantly more likely to contain females (p = 0.037) and less likely to include HIV diagnoses with male-to-male sexual contact reported as a possible exposure (p<0.001) compared to larger clusters (n≥3).

Conclusion

Migrants appear to be at elevated risk of HIV acquisition, in part due to intimate relationships between migrants from the same country of origin, and in part due to risks associated with the broader Australian HIV epidemic. However, there was no evidence of large transmission clusters driven by heterosexual transmission between migrants. A multipronged approach to prevention of HIV among migrants is warranted.
