Many Australian gay men do not get tested for HIV at the recommended frequency. Barriers to HIV testing may be reduced by the availability of home HIV self-testing (HHST). An online cross-sectional questionnaire was conducted with 2,306 Australian gay men during 2009. Multivariate logistic regression identified factors associated with being likely to increase testing frequency if HHST was available, among previously-tested and never-tested men. Among 2,018 non-HIV-positive men, 83.9% had been tested. Two-thirds indicated they would test more often if HHST was available irrespective of previous testing history. In multivariate analysis, independent predictors of increased testing frequency with HHST included preferences for more convenient testing, not having to see a doctor when testing and wanting immediate results among all men, as well as not being from an Anglo-Australian background and recent unprotected anal sex with casual partners among previously-tested men only. The majority of gay men report that being able to test themselves at home would increase their frequency of HIV testing.
For men who do not engage in risky sex, the decision not to test is probably reasonable, but those who engage in non condom-based risk reduction may be at some increased risk and should be encouraged to test relatively often. Changes to Australia's national HIV testing policy may ameliorate some of the need to return for second clinic visits to receive results, but the policy still requires full implementation, including the introduction of rapid point-of-care HIV testing to Australia. Among men who engage in UAIC, there appears to be a particular need for information about the benefits of early treatment after HIV diagnosis and about the relative likelihood of experiencing HIV seroconversion illness.
IntroductionHIV diagnoses among gay and bisexual men have increased over the past decade in Australia. HIV point-of-care testing (POCT) was introduced in Australia in 2011 as a strategy to increase HIV testing by making the testing process more convenient. We surveyed gay and bisexual men undergoing POCT to assess barriers to HIV testing and characteristics associated with not having previously tested for HIV (never testing).MethodsDuring 2011 and 2012, gay and bisexual men who were undergoing POCT at four Sydney sexual health clinics self-completed questionnaires assessing testing history and psychological and structural barriers to HIV testing. Bivariate and multivariate logistic regression was used to assess associations between patient characteristics and never testing.ResultsOf 1093 participants, 981 (89.9%) reported ever testing for HIV and 110 (10.1%) never testing. At least one barrier to testing was reported by 1046 men (95.7%), with only 47 men (4.3%) not reporting any barrier to testing. The most commonly reported barriers to testing were annoyance at having to return for results (30.2%), not having done anything risky (29.6%), stress in waiting for results (28.4%), being afraid of testing positive (27.5%) and having tested recently (23.2%). Never testing was independently associated with being non-gay-identified (adjusted odds ratio [AOR]: 1.9; 95% confidence interval [CI]: 1.1–3.2), being aged less than 25 years (AOR: 2.4; 95% CI: 1.6–3.8), living in a suburb with few gay couples (AOR: 1.9; 95% CI: 1.2–3.0), being afraid of testing HIV-positive (AOR: 1.6; 95% CI: 1.0–2.4), not knowing where to test (AOR: 3.8; 95% CI: 1.3–11.2) and reporting one or no sexual partners in the last six months (AOR: 2.7; 95% CI: 1.2–6.2).ConclusionsBarriers to HIV testing were commonly reported among the clinic-based gay and bisexual men in this study. Our findings suggest further health promotion and prevention strategies are needed to address the knowledge, attitudes and behavioural factors associated with never testing.
BackgroundDetermine HIV Combo (DHC) is the first point of care assay designed to increase sensitivity in early infection by detecting both HIV antibody and antigen. We conducted a large multi-centre evaluation of DHC performance in Sydney sexual health clinics.MethodsWe compared DHC performance (overall, by test component and in early infection) with conventional laboratory HIV serology (fourth generation screening immunoassay, supplementary HIV antibody, p24 antigen and Western blot tests) when testing gay and bisexual men attending four clinic sites. Early infection was defined as either acute or recent HIV infection acquired within the last six months.ResultsOf 3,190 evaluation specimens, 39 were confirmed as HIV-positive (12 with early infection) and 3,133 were HIV-negative by reference testing. DHC sensitivity was 87.2% overall and 94.4% and 0% for the antibody and antigen components, respectively. Sensitivity in early infection was 66.7% (all DHC antibody reactive) and the DHC antigen component detected none of nine HIV p24 antigen positive specimens. Median HIV RNA was higher in false negative than true positive cases (238,025 vs. 37,591 copies/ml; p = 0.022). Specificity overall was 99.4% with the antigen component contributing to 33% of false positives.ConclusionsThe DHC antibody component detected two thirds of those with early infection, while the DHC antigen component did not enhance performance during point of care HIV testing in a high risk clinic-based population.
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.
IntroductionThe HIV Strategy in New South Wales (NSW) Australia aims to virtually eliminate HIV transmission by 2020. We estimated the 2016 HIV diagnosis and care cascade for the state of NSW, with a focus on introducing population‐based data to improve data quality and assess progress towards the UNAIDS 90‐90‐90 targets.MethodsTo estimate the number of people living with diagnosed HIV (PLDHIV) we used NSW data from the Australian National HIV Registry, enhanced by surveillance among people recently diagnosed with HIV to improve migration estimates. The number of undiagnosed PLHIV was estimated using back‐projection modelling by CD4 count at diagnosis. De‐duplicated prescription claims data were obtained from the Australian Pharmaceutical Benefits Scheme (PBS), and were combined with an estimate for those ineligible, to determine the number of PLDHIV on antiretroviral therapy (ART). Data from a clinic network with 87% coverage of PLDHIV in NSW enabled the estimation of the number on ART who had HIV suppression.Results and discussionWe estimated that 10,110 PLHIV resided in NSW in 2016 (range 8400 to 11,720), among whom 9230 (91.3%) were diagnosed, and 8490 (92.0% of those diagnosed) were receiving ART. Among PLDHIV receiving ART, 8020 (94.5%) had suppressed viral load (<200 HIV‐1 RNA copies/mL). Overall, 79.3% of all PLHIV had HIV virological suppression.Conclusion
NSW has met each of the UNAIDS 90‐90‐90 targets. The enhanced surveillance methods and data collection systems improved data quality. Measuring and meeting the 90‐90‐90 targets is feasible and could be achieved in comparable parts of the world.
