IntroductionContemporary responses to HIV embrace biomedical prevention, particularly treatment as prevention (TasP) and pre-exposure prophylaxis (PrEP). However, large-scale implementation of biomedical prevention should be ideally preceded by assessments of their community acceptability. We aimed to understand contemporary attitudes of gay and bisexual men (GBM) in Australia towards biomedical-based HIV prevention and propose a framework for their measurement and ongoing monitoring.MethodsA cross-sectional, online survey of GBM ≥18 years has been conducted annually in Victoria, Australia, since 2008. In 2016, 35 attitudinal items on biomedical HIV prevention were added. Items were scored on five-point Likert scales. We used principal factor analysis to identify key constructs related to GBM’s attitudes to biomedical HIV prevention and use these to characterise levels of support for TasP and PrEP.ResultsA total of 462 HIV-negative or HIV-status-unknown men, not using PrEP, provided valid responses for all 35 attitudinal items. We extracted four distinct and interpretable factors we named: ‘Confidence in PrEP’, ‘Judicious approach to PrEP’, ‘Treatment as prevention optimism’ and ‘Support for early treatment’. High levels of agreement were seen across PrEP-related items; 77.9% of men agreed that PrEP prevented HIV acquisition and 83.6% of men agreed that users were protecting themselves. However, the agreement levels for HIV TasP items were considerably lower, with <20% of men agreeing treatment (undetectable viral load) reduced HIV transmission risk.ConclusionsBetter understanding of community attitudes is crucial for shaping policy and informing initiatives that aim to improve knowledge, acceptance and uptake of biomedical prevention. Our analyses suggest confidence in, acceptability of and community support for PrEP among GBM. However, strategies to address scepticism towards HIV treatment when used for prevention may be needed to optimise combination biomedical HIV prevention.

Social networking sites (SNS) are increasingly popular platforms for health promotion. Advancements in SNS health promotion require quality evidence; however, interventions are often not formally evaluated. This study aims to describe evaluation practices used in SNS health promotion. A systematic review was undertaken of Medline, PsycINFO, Scopus, EMBASE, CINAHL Plus, Communication and Mass Media Complete, and Cochrane Library databases. Articles published between 2006 and 2013 describing any health promotion intervention delivered using SNS were included. Forty-seven studies were included. There were two main evaluation approaches: closed designs (n = 23), which used traditional research designs and formal recruitment procedures; and open designs (n = 19), which evaluated the intervention in a real-world setting, allowing unknown SNS users to interact with the content without enrolling in research. Closed designs were unable to assess reach and engagement beyond their research sample. Open designs often relied on weaker study designs with no use of objective outcome measures and yielded low response rates. Barriers to evaluation included low participation rates, high attrition, unknown representativeness and lack of comparison groups. Acceptability was typically assessed among those engaged with the intervention, with limited population data available to accurately assess intervention reach. Few studies were able to assess uptake of the intervention in a real-life setting while simultaneously assessing effectiveness of interventions with research rigour. Through use of quasi-experimental or well designed before-after evaluations, in combination with detailed engagement metrics, it is possible to balance assessment of effectiveness and reach to evaluate SNS health promotion. Social networking sites (SNS), such as Facebook, are popular platforms for health promotion. This systematic review describes previous studies' methods for evaluating SNS health promotion. It found that few studies were able to both assess reach of an intervention in a real-life setting while using rigorous research designs.

Objective:To evaluate the Indigenous sexual health promotion program in the Torres Strait 2006–2012 that culminated in an education‐entertainment radio drama, Kasa Por Yarn(KPY). Methods:A mixed methods approach applied to unpublished program documents and program‐derived peer‐reviewed publications was utilised. Results:Early initiatives established a strong partnership with Torres Strait Islander stakeholders. Significant community engagement throughout ensured a positive process. Telephone survey data (n=100, TSI, 15–24 years) found: 95% had heard of KPY and 80% listened to 2 or more episodes (reach); 86% recalled storylines/characters (recall); and 54% talked about KPY to family/friends (resonance). There was improvement in sexual health knowledge scores (p<0.00) in the 15–19‐year‐old Torres Strait Islander population between 2007 and 2012. The 2012 15–24‐year‐old population exposed to KPY had higher sexual health knowledge scores compared with those unexposed (p=0.02). Conclusions:This is an uncommon comprehensive evaluation of population‐based sexual health communications strategies delivered over years in a remote Australian setting. The findings are encouraging but demonstrate that positive shifts take time and are incremental. Implications:In addition to clinical strategies, strategic and sustained investment in sexual health promotion expertise that leads community partnership and program development is required to reduce youth risk and prevent HIV/AIDS in remote populations.
