Background There has been a rapid rise in the popularity of electronic cigarettes (e-cigarettes) over the last decade, with growth predicted to continue. The uptake of these devices has escalated despite inconclusive evidence of their efficacy as a smoking cessation device and unknown long-term health consequences. As smoking rates continue to drop or plateau in many well-developed countries, transnational tobacco companies have transitioned into the vaping industry and are now using social media to promote their products. Evidence indicates e-cigarettes are being marketed on social media as a harm reduction alternative, with retailers and manufacturers utilizing marketing techniques historically used by the tobacco industry. Objective This study aimed to identify and describe the messages presented in e-cigarette–related social media (Twitter, YouTube, Instagram, and Pinterest) promotions and discussions and identify future directions for research, surveillance, and regulation. Methods Data sources included MEDLINE, Scopus, ProQuest, Informit, the Journal of Medical Internet Research , and Google Scholar. Included studies were published in English between 2007 and 2017, analyzed content captured from e-cigarette–related social media promotions or discussions, and reported results for e-cigarettes separately from other forms of tobacco and nicotine delivery. Database search ceased in October 2017. Initial searches identified 536 studies. Two reviewers screened studies by title and abstract. One reviewer examined 71 full-text articles to determine eligibility and identified 25 studies for inclusion. This process was undertaken with the assistance of the Web-based screening and data extraction tool—Covidence. The review was registered with the Joanna Briggs Institute (JBI) Systematic Reviews database and followed the methodology for JBI Scoping Reviews. Results Several key messages are being used to promote e-cigarettes including as a safer alternative to cigarettes, efficacy as a smoking cessation aid, and for use where smoking is prohibited. Other major marketing efforts aimed at capturing a larger market involve promotion of innovative flavoring and highlighting the public performance of vaping. Discussion and promotion of these devices appear to be predominantly occurring among the general public and those with vested interests such as retailers and manufacturers. There is a noticeable silence from the public health and government sector in these discussions on social media. Conclusions The social media landscape is dominated by pro-vaping messages disseminated by the vaping industry and vaping proponents. The uncertainty surrounding e-cigarette regulation expressed within the public health field appears not to be reflected in ongoing social media dialogues and highlights the need for public health professionals to interact with the public to actively in...

Globally, drowning is one of the ten leading causes of child mortality. Children aged <5 years are particularly at risk, and children and young people continue to be overrepresented in drowning statistics. Accordingly, evidence informed interventions to prevent children drowning are of global importance. This review aimed to identify, assess and analyse public health interventions to reduce child drowning and investigate the use of behavioural theories and evaluation frameworks to guide child drowning prevention. Thirteen databases were searched for relevant peer reviewed articles. The systematic review was guided by the PRISMA criteria and registered with PROSPERO. Fifteen articles were included in the final review. Studies were delivered in high, middle and low income countries. Intervention designs varied, one-third of studies targeted children under five. Almost half of the studies relied on education and information to reduce drowning deaths, only three studies used a multi-strategy approach. Minimal use of behavioural theories and/or frameworks was found and just one-third of the studies described formative evaluation. This review reveals an over reliance on education and information as a strategy to prevent drowning, despite evidence for comprehensive multi-strategy approaches. Accordingly, interventions must be supported that use a range of strategies, are shaped by theory and planning and evaluation frameworks, and are robust in intervention design, delivery and evaluation methodology. This approach will provide sound evidence that can be disseminated to inform future practice and policy for drowning prevention.

Introduction: Asian sex workers are a significant part of the Australian sex industry. Criminal laws, racism, isolation, poor English language skills and stigma and discrimination combine to increase the vulnerability of Asian sex workers in Australia. To inform service delivery and potential legislative reform, we undertook a study of sex worker health and safety in Western Australia with a focus on Asian sex workers.Methods: This was a mixed methods study in which peer researchers played an essential role. We undertook a survey (available online and in paper form and translated into three languages other than English), semi-structured interviews with sex workers, and interviews with key advisors.Results: In our study, Asian sex workers were older, had lower levels of education, more likely to have sex work as their main source of income, work longer hours and work exclusively in a shop-front massage parlor compared to their non-Asian counterparts. The vast majority of Asian sex workers in our study said they had poor English language skills and the greatest proportion spoke Chinese languages. Sex work had a positive impact on the well-being of many respondents, and their level of psychological distress was similar to the general Australian population. Stress and “bad clients” were common negative impacts of sex work. Asian study participants were less likely than their non-Asian counterparts to smoke, undertake risky drinking or use illicit drugs. A similar proportion of Asian sex workers reported being assaulted compared to their non-Asian counterparts.Discussion/Conclusion: The major challenges facing Asian sex workers in WA seem to be stigma and discrimination, stress, social isolation, and confusion about their legal standing leading to a fear of authorities, particularly the police. Our findings support the need for enhanced targeted peer-based health promotion outreach services for Asian sex workers, increased Asian language services in sexual health clinics and decriminalization of sex work.

Background As the majority of Twitter content is publicly available, the platform has become a rich data source for public health surveillance, providing insights into emergent phenomena, such as vaping. Although there is a growing body of literature that has examined the content of vaping-related tweets, less is known about the people who generate and disseminate these messages and the role of e-cigarette advocates in the promotion of these devices. Objective This study aimed to identify key conversation trends and patterns over time, and discern the core voices, message frames, and sentiment surrounding e-cigarette discussions on Twitter. Methods A random sample of data were collected from Australian Twitter users who referenced at least one of 15 identified e-cigarette related keywords during 2012, 2014, 2016, or 2018. Data collection was facilitated by TrISMA (Tracking Infrastructure for Social Media Analysis) and analyzed by content analysis. Results A sample of 4432 vaping-related tweets posted and retweeted by Australian users was analyzed. Positive sentiment (3754/4432, 84.70%) dominated the discourse surrounding e-cigarettes, and vape retailers and manufacturers (1161/4432, 26.20%), the general public (1079/4432, 24.35%), and e-cigarette advocates (1038/4432, 23.42%) were the most prominent posters. Several tactics were used by e-cigarette advocates to communicate their beliefs, including attempts to frame e-cigarettes as safer than traditional cigarettes, imply that federal government agencies lack sufficient competence or evidence for the policies they endorse about vaping, and denounce as propaganda “gateway” claims of youth progressing from e-cigarettes to combustible tobacco. Some of the most common themes presented in tweets were advertising or promoting e-cigarette products (2040/4432, 46.03%), promoting e-cigarette use or intent to use (970/4432, 21.89%), and discussing the potential of e-cigarettes to be used as a smoking cessation aid or tobacco alternative (716/4432, 16.16%), as well as the perceived health and safety benefits and consequences of e-cigarette use (681/4432, 15.37%). Conclusions Australian Twitter content does not reflect the country’s current regulatory approach to e-cigarettes. Rather, the conversation on Twitter generally encourages e-cigarette use, promotes vaping as a socially acceptable practice, discredits scientific evidence of health risks, and rallies around the idea that e-cigarettes should largely be outside the bounds of health policy. The one-sided nature of the discussion is concerning, as is the lack of disclosure and transparency, especially among vaping enthusiasts who dominate the majority of e-cigarette discussions on Twitter, where it is unclear if comments are endorsed, sanctioned, or even supported by the industry.

Introduction: Since the emergence of the HIV pandemic in the 1980s, high rates of condom use for penetrative sex have been reported among sex workers in Australia. The sex industry in Australia and elsewhere has changed over the previous decade with increasing proportions of sex workers working privately and lower proportions of sex workers working in brothels. There has also been some evidence of reductions in condom use, particularly during penetrative oral sex. We therefore decided to investigate sex workers' use of condoms during penetrative sex with clients.Methods: This was a cross-sectional mixed methods study of sex workers in Western Australia. The study involved an environmental scan of the sex industry in Western Australia, visits to brothels and other sexual services premises, a survey of sex workers and in-depth interviews.Results: We surveyed 354 male, female, and transgender sex workers in Western Australia. We found unexpectedly low rates of reported condom use with clients for all forms of penetrative sex. Of respondents who reported providing this type of service, 33% reported that all clients used condoms during oral sex, 69% during vaginal sex and 59% during anal sex. High levels of client demand for condomless sex was also reported, with 42% of sex workers reporting that all or most clients requested condomless oral sex. Increasing client demand, fear of losing clients and the ability to charge more for condomless sex were reported reasons for providing this service.Conclusions: There has been an apparent increase in sex workers reporting condomless penetrative sex with clients in Western Australia compared to a previous cross-sectional study. An increase in private sex work and client demand for condomless sex together with an economic downturn leading to increased competition for clients may be important contributing factors.

Background Vaping is a relatively new practice, and therefore its symbolic meanings and social practices are yet to be fully understood, especially within Australia where the practice is strictly regulated. This study aimed to examine vapers motivations for use, reinforcing influences, and association with the vaper subculture. Methods Working from a constructivist epistemology and a symbolic interaction framework, in-depth interviews were conducted with a purposive sample of 37 current (89%) and former (11%) adult vapers, 70% male, mean age of 32.5. Data was analysed via thematic analysis. Results Vapers largely started vaping to quit smoking and underwent common experiences during their initiation phase. Subsequently, vapers tended to adopt one of two dominant identities, that of the ‘cloud chaser’ or the ‘substitute’, which some users moved between during different stages of their vaping career. The social and symbolic meaning of e-cigarettes and vaping varied and involved concepts of harm reduction, addiction, pleasure, stigma and community, and for some, connection to the vaper subculture. Conclusions Understanding the complexities of vaping, and the nuanced differences of ‘cloud chasers’ and ‘substitute’ vapers may have important implications for health communication, research and policy. E-cigarette users within this sample were not a homogeneous group and differed in their motivations for use, association with the vaper subculture and relationship with the vape community. These findings provide new insights into the socialisation process and subsequent identity adoption of vapers within the unique regulatory environment of Western Australia.
