A prescription model for vapes: the way we 'do' medicines policy in Australia.

On 2 May 2023, the Australian Federal Government announced a suite of reforms aimed at ensuring the effectiveness of the prescription model of regulation of vaping (or e-cigarette) products in Australia. These reforms are intended to protect Australians, particularly young people, from the harms of vaping and nicotine dependence. The ensuing public debate on the issue has often created the impression that the options under consideration are to either retain 'recently introduced' prescription regulation or to 'revert to' a retail supply approach. However, the sale of nicotine vapes by retailers such as tobacconists and convenience stores has never been lawful in Australia. The reforms do not seek to change the way nicotine vaping products are regulated, but rather to ensure that the existing prescription model can be effectively enforced and can function as originally intended. This paper describes the historical context and rationale for strengthening prescription regulation of vapes in this country.

Parent's awareness of, and influence on, their 14-17-year-old child's vaping and smoking behaviours; an analysis of 3242 parent-child pairs in Australia.

BACKGROUND: Vaping by young people in Australia is a rapidly emerging public health issue. Evidence shows that parental behaviours and attitudes can play a key role in influencing adolescent behaviours. Considering the health harms of vaping and evidence that it can be a gateway to tobacco smoking for never-smokers, it is important to understand whether parents' smoking and vaping behaviours influence their teenage children's smoking and vaping behaviours. METHODS: Online cross-sectional surveys as part of the Generation Vape study, conducted in Australia in 2021/2022, were used to assess parents' influence on, and awareness of, one of their 14-17-year-old child's vaping and smoking behaviours. Participants were 3242 parents and 3242 14-17-year-old teenage children. RESULTS: The risk of vaping and smoking uptake among 14-17-year-old teenagers was 42% (p = 0.003) and 97% (p < 0.001) higher, respectively, if their parent was an ever-vaper. The risk of vaping and smoking uptake among teenagers was 81% (p < 0.001) and 159% (p < 0.001) higher, respectively, if their parent was an ever-smoker. Parents of teenagers who have not vaped were considerably better at correctly predicting this (97% correct) than parents of teenagers who have vaped (70% correct). Compared to parents, teenagers tended to have less agreement with statements suggesting vaping is unsafe or harmful, and more agreement with statements suggesting vaping is relatively safe. CONCLUSIONS: Parental smoking and vaping behaviours are associated with those of their children. Hence, it is important that both tobacco and vaping control policies and interventions are designed to influence behaviours of all demographics, consistent with the evidence.

Perceptions of adequacy of fruit and vegetable intake as a barrier to increasing consumption.

AIM: To investigate New South Wales adults' perceived adequacy of their fruit and vegetable consumption and to identify the barriers to consumption. METHOD: An online cross-sectional survey of a sample of adults in New South Wales (n = 1603) in February 2019 measured self-reported fruit and vegetable intakes, perception of consumption adequacy and barriers to consumption. Proportions of participants whose reported consumption met the daily recommended serves of fruit and vegetables per day were calculated. Chi-square and Fisher's exact tests were used to explore differences between demographic characteristics and meeting fruit and vegetable recommendations. For those not meeting recommendations, Chi-square and Fisher's exact tests were used to explore perceived adequacy of intake as a potential barrier to consumption. RESULTS: The sample included 52.7% women, 40.0% aged under 40 years and 28.6% over 59 years, 68.2% lived in a major city, and 32.6% were university educated. Overall, 64.8% of participants reported consuming adequate fruit and 12.4% reported consuming adequate vegetables. Of those consuming less than the guidelines, 21.3% perceived that they were eating enough fruit and 53.7% perceived they were eating enough vegetables. The most common barriers to eating more fruit were preference for other foods (29.6%), fruit spoiling too quickly (28.3%), and habit (27.0%). The most common barriers to eating more vegetables were the perception that they eat enough (26.8%), preference for other foods (21.9%), and habit (19.7%). CONCLUSIONS: Greater efforts are needed to support the public to eat adequate fruit and vegetables, consistent with dietary guidelines. Public education campaigns specifically targeting increasing vegetable consumption are required to address knowledge gaps, given a large proportion of our study population consumed inadequate levels of vegetables yet perceived their intake to be adequate.

E-cigarette use by people who smoke or have recently quit, New South Wales, 2016-2020.

OBJECTIVE: To examine e-cigarette use by adults who smoke or have recently quit, and demographic characteristics associated with their use; to assess reasons for using e-cigarettes. DESIGN: The Cancer Institute NSW Tobacco Tracking Survey (CITTS) is an ongoing, serial, cross-sectional telephone survey study (40 interviews each week). This report is based on interviews during 4 January 2016 - 31 December 2020. SETTING, PARTICIPANTS: Randomly selected New South Wales adults who are current smokers (smoked cigarettes, pipes, or other tobacco products daily, weekly, or less often) or recent quitters (smoked tobacco products in the past twelve months but who no longer smoked). MAIN OUTCOMES: E-cigarette use by age group; reasons for using e-cigarettes. RESULTS: CITTS callers rang 1 494 233 randomly selected numbers; in 203 203 answered calls (13.6%), 11 125 people were eligible for the survey (5.5% of answered calls), of whom 10 004 completed the survey interview, including the question about whether they used e-cigarettes (89.9%). Overall e-cigarette use increased from 6.6% of respondents in 2016 to 13.0% in 2020 (adjusted odds ratio, 1.86; 95% confidence interval [CI], 1.47-2.36). The proportion of respondents aged 18-24 years who reported e-cigarette use increased from 18.4% (95% CI, 12.9-23.9%) in 2018 to 27.2% (95% CI, 20.5-33.9%) in 2020, a larger proportion than for any other age group. The leading reasons offered for e-cigarette use were "to help me quit smoking" (33%; 95% CI, 30-37%) and "to cut down on the number of cigarettes I smoke" (25%; 95% CI, 22-28%). CONCLUSION: The increase between 2016 and 2020 in the proportions of young adults who smoke or have recently quit who use e-cigarettes undermines claims that these products are designed for older smokers who have struggled to quit using other methods.

Changes in public support for alcohol policies in NSW, Australia, 2013-2019.

OBJECTIVES: Alcohol contributes to significant health, social and economic burdens worldwide, but evidence-based policy options can reduce the harm associated with alcohol use. The aim of this paper is to understand factors influencing public support for various alcohol policies in New South Wales (NSW), Australia, and to determine any change over time. METHODS: An online survey of adults in NSW, in 2013 (n = 2482), 2016 (n = 1585) and 2019 (n = 1601), assessed support for alcohol policies. Multivariable logistic regression models examined the change in support over time, adjusting for demographics, alcohol consumption, smoking status and knowledge of alcohol as a risk factor for cancer. RESULTS: Most participants (68-72%) supported policies preventing underage internet users from exposure to alcohol advertising, and banning alcohol sponsorship of underage music and sporting events. Fiscal policies and restrictions on the number of alcohol outlets were the least supported policies (<40% support). Compared with 2013, participants in 2016 and 2019 were less likely to support policies increasing price, applying a volumetric tax and reducing the number of alcohol outlets. In 2019, more than 55% of respondents were aware that alcohol was a cancer risk factor, and knowledge of that relationship was associated with an increased likelihood of support for alcohol policies. CONCLUSIONS: Support was greatest for alcohol harm-reduction policies that had less impact on an individual's drinking. Overall, support for alcohol policies in NSW is not increasing. Initiatives to raise awareness about the health consequences of alcohol use, together with effective alcohol policies, are needed to counter industry influence on decision makers and negative public discourse.

Vaping product access and use among 14-17-year-olds in New South Wales: a cross-sectional study.

OBJECTIVES: We assessed access to vaping products and types of products used and the factors associated with vaping and smoking among young people in the state of New South Wales (NSW), Australia. METHODS: A cross-sectional survey was conducted with a sample of 721 young people aged 14 to 17 years from NSW recruited through online panels. Poisson regression with robust variance was used to estimate relative risks of ever-vaping and ever-smoking. RESULTS: Almost one-third of the sample (32%, n=233) reported being an ever-vaper, of which more than half (54%) had never smoked prior to starting vaping. Ever-vaping was independently associated with age and being Aboriginal or Torres Strait Islander, and ever-smoking was independently associated with being male. Ever-smokers were seven times more likely to be ever-vapers than those who had never smoked, and ever-vapers were 18 times more likely to be ever-smokers than those who had never vaped. Among ever-vapers who reported which type of device they were using, 86% reported the use of disposable products. "Flavourings and taste" was rated as the most important characteristic of vapes. More than half of ever-vapers reported getting the last vape they used from their friends (55%, n=130). More than half of ever-vapers had used a vape that they knew contained nicotine (53%, n=123). CONCLUSIONS: Vaping was the strongest risk factor for smoking, and vice versa, suggesting there is not a straightforward, unidirectional relationship between vaping and smoking in young people. Young people appear to be readily accessing nicotine vaping products, which are often disposable and flavoured, through both social and commercial channels. IMPLICATIONS FOR PUBLIC HEALTH: Stronger enforcement of federal and state policies designed to protect young people from vaping products is urgently needed.

Monitoring changes in community support for policies on obesity prevention.

OBJECTIVE: To investigate the New South Wales (NSW) community's support for obesity prevention policies and concern for food marketing and promotion issues, and to determine any demographic differences or changes over time. METHODS: In 2013 (n=2474), 2016 (n=1602) and 2019 (n=1613) a sample of adults who were representative of the NSW population for age, gender, education and location was asked about support for policy initiatives that influence the food environment. Analysis identified the characteristics of those who supported policies and variation in support over time. RESULTS: There were limited changes in support over time; however, support for many policies was strong and sustained. In 2019, support was highest for regulation of claims about nutrition (77.2%), and health warning labels (75.7%). Support for a ban on unhealthy food advertising that targets children (64.6%) had decreased since 2013. Women, older people and those who were aware that obesity was a risk factor for cancer were generally more likely to support policies. Parents were more likely than non-parents to be concerned about positioning unhealthy food at supermarket checkouts (OR 1.32) and unhealthy outdoor advertisements (OR 1.22). Concern increased in 2019 for unhealthy marketing on the internet (OR 1.21). CONCLUSIONS: This study shows public support for policy options at moderate to high levels but not increasing in the six-year study period. Implications for public health: These results form part of a package that, along with the well-established evidence, makes the case for policy action in Australia.

Pathways to a cancer-free future: a protocol for modelled evaluations to minimise the future burden of colorectal cancer in Australia.

INTRODUCTION: With almost 50% of cases preventable and the Australian National Bowel Cancer Screening Program in place, colorectal cancer (CRC) is a prime candidate for investment to reduce the cancer burden. The challenge is determining effective ways to reduce morbidity and mortality and their implementation through policy and practice. Pathways-Bowel is a multistage programme that aims to identify best-value investment in CRC control by integrating expert and end-user engagement; relevant evidence; modelled interventions to guide future investment; and policy-driven implementation of interventions using evidence-based methods. METHODS AND ANALYSIS: Pathways-Bowel is an iterative work programme incorporating a calibrated and validated CRC natural history model for Australia (Policy1-Bowel) and assessing the health and cost outcomes and resource use of targeted interventions. Experts help identify and prioritise modelled evaluations of changing trends and interventions and critically assess results to advise on their real-world applicability. Where appropriate the results are used to support public policy change and make the case for optimal investment in specific CRC control interventions. Fourteen high-priority evaluations have been modelled or planned, including evaluations of CRC outcomes from the changing prevalence of modifiable exposures, including smoking and body fatness; potential benefits of daily aspirin intake as chemoprevention; increasing CRC incidence in people aged <50 years; increasing screening participation in the general and Aboriginal and Torres Strait Islander populations; alternative screening technologies and modalities; and changes to follow-up surveillance protocols. Pathways-Bowel is a unique, comprehensive approach to evaluating CRC control; no prior body of work has assessed the relative benefits of a variety of interventions across CRC development and progression to produce a list of best-value investments. ETHICS AND DISSEMINATION: Ethics approval was not required as human participants were not involved. Findings are reported in a series of papers in peer-reviewed journals and presented at fora to engage the community and policymakers.

A systematic evaluation of digital nutrition promotion websites and apps for supporting parents to influence children's nutrition.

BACKGROUND: Globally children's diet quality is poor. Parents are primary gatekeepers to children's food intake; however, reaching and engaging parents in nutrition promotion can be challenging. With growth in internet and smartphone use, digital platforms provide potential to disseminate information rapidly to many people. The objectives of this review were to conduct a comprehensive and systematic evaluation of nutrition promotion via websites and apps supporting parents to influence children's nutrition, from three different perspectives: 1) current evidence base, 2) end user (parent) experience and 3) current commercial offerings. METHODS: Three systematic reviews were undertaken of (1) studies evaluating the effectiveness for digital platforms for improving nutrition in children and parents, (2) studies conducting user-testing of digital tools with parents, (3) websites and apps providing lunch-provision information to parents. Searches were conducted in five databases for reviews one and two, and systematic search of Google and App Store for review three. Randomised controlled trials, cohort and cross-sectional and qualitative studies (study two only) were included if published in English, from 2013, with the intervention targeted at parents and at least 50% of intervention content focused on nutrition. Search results were double screened, with data extracted into standardised spreadsheets and quality appraisal of included search results. RESULTS: Studies evaluating digital nutrition interventions targeting parents (n = 11) demonstrated effectiveness for improving nutrition outcomes, self-efficacy and knowledge. Six of the included randomised controlled trials reported digital interventions to be equal to, or better than comparison groups. User-testing studies (n = 9) identified that digital platforms should include both informative content and interactive features. Parents wanted evidence-based information from credible sources, practical tools, engaging content and connection with other users and health professionals. Websites targeting lunch provision (n = 15) were developed primarily by credible sources and included information-based content consistent with dietary guidelines and limited interactive features. Lunchbox apps (n = 6), developed mostly by commercial organisations, were more interactive but provided less credible information. CONCLUSIONS: Digital nutrition promotion interventions targeting parents can be effective for improving nutrition-related outcomes in children and parents. As demonstrated from the lunchbox context and user-testing with parents, they need to go beyond just providing information about positive dietary changes, to include the user-desired features supporting interactivity and personalisation.

Accessing the most lethal product on the market: community perceptions of tobacco accessibility in NSW, Australia.

AIM: This study aims to describe the perceived ease of accessing tobacco retail outlets in New South Wales (NSW), Australia, and the sociodemographic factors associated with reported higher density of tobacco retail outlets. METHODS: A cross-sectional online survey was conducted with a sample of NSW adults in February 2019. The accessibility of cigarettes was assessed and a binary logistic regression model was used to examine characteristics associated with having four or more retailers within a 5-minute drive of their home. RESULTS: A total of 3213 NSW adults completed the survey. The vast majority of participants, 89.9% (n = 2888), described cigarettes as being easily accessed from where they live. Half of the participants (50.7%) reported having four or more tobacco retail outlets within a 5-minute drive of their home. Never-smokers were significantly less likely than daily smokers to report four or more tobacco retailers within a 5-minute drive of their home, although non-smokers may be less likely to identify tobacco retailers. Females, those living in regional areas of NSW and those with a university qualification were also less likely to report having four or more tobacco retailers within a 5-minute drive of their home. CONCLUSION: The ease of access to tobacco retailers in NSW is incongruent with the significant health risks associated with tobacco use and highlights the need for measures to reduce the supply of tobacco, such as a fee-based tobacco licensing system.

Lung cancer mortality in Australia in the twenty-first century: How many lives can be saved with effective tobacco control?

OBJECTIVES: To estimate the number of past and future lung cancer deaths that have already been averted by tobacco control initiatives in Australia, and to estimate the number of additional deaths averted under various smoking scenarios. METHODS: We predicted lung cancer mortality rates and case numbers to 2100 using a previously validated generalized linear model based on age, birth cohort and population cigarette smoking exposure. We estimated the impact of various tobacco control scenarios: 'actual tobacco control' (incorporating the aggregate effect of past and current taxation, plain packaging, mass media campaigns and other initiatives) and scenarios where 10%, 5% and 0% smoking prevalence was achieved by 2025, all of which were compared to a counterfactual scenario with the highest historical smoking consumption level continuing into the future as if no tobacco control initiatives had been implemented. RESULTS: Without tobacco control, there would have been an estimated 392,116 lung cancer deaths over the period 1956-2015; of these 20% (78,925 deaths; 75,839 males, 3086 females) have been averted due to tobacco control. However, if past and current measures continue to have the expected effect, an estimated 1.9 million deaths (1,579,515 males, 320,856 females; 67% of future lung cancer deaths) will be averted in 2016-2100. If smoking prevalence is reduced to 10%, 5% or 0% by 2025, an additional 97,432, 208,714 or 360,557 deaths could be averted from 2016 to 2100, respectively. CONCLUSION: Tobacco control in Australia has had a dramatic impact on the number of people dying from lung cancer. Several hundred thousand more lung cancer deaths could be averted over the course of the century if close-to-zero smoking prevalence could be achieved in the next decade.

Australia's plain tobacco packs: anticipated and actual responses among adolescents and young adults 2010-2013.

BACKGROUND: In December 2012, Australia introduced world-first legislation mandating plain packaging for all tobacco products. To date, there is very little evidence on youth responses to the changed packs. AIM: To assess attitudes towards, and responses to, tobacco plain packs preimplementation and postimplementation. METHODS: The Tobacco Promotion Impact Study (TPIS) was a yearly cross-sectional telephone survey of adolescents and young adults (12-24 years) from the states of New South Wales (NSW) and Queensland, conducted at three time points preimplementation (June 2010; June 2011; June 2012) and one time point postimplementation (June 2013; total n=8820). RESULTS: There were significant increases in support for plain packaging from preimplementation to postimplementation for: never smokers (56% in 2012 vs 63% in 2013; OR=0.77, 95% CI 0.65 to 0.90, p=0.001), experimenters/ex-smokers (55% in 2012 vs 72% in 2013; OR=0.51, 95% CI 0.38 to 0.68, p<0.001) and current smokers (35% in 2012 vs 55% in 2013; OR=0.49, 95% CI 0.32 to 0.75, p=0.001). At postimplementation, 16% of never smokers reported that plain packaging made them less likely to try smoking and 18% of experimenters/ex-smokers reported that plain packaging made them less likely to smoke again. Youth were significantly less likely to have anticipated these responses preimplementation (never smokers: 8% in 2011; OR=0.43, 95% CI 0.28 to 0.65, p<0.00; experimenters/ex-smokers: 11%; OR=0.65, 95% CI 0.52 to 0.82, p<0.001). At postimplementation, 34% of smokers reported a quitting-related response to plain packaging (tried to quit or thought about quitting); the proportion who anticipated such a response preimplementation was significantly less (14% in 2011; OR=0.33, 95% CI 0.20 to 0.53, p<0.001). 28% of smokers reported a social denormalisation response at postimplementation (hid their pack from view, used a case to cover their pack, felt embarrassed); the proportion who anticipated such a response preimplementation was significantly less (9% in 2011; OR=0.24, 95% CI 0.14 to 0.42, p<0.001). CONCLUSIONS: The actual response of youth to plain packaging was greater than anticipated prior to their introduction, and support for plain packaging increased from preimplementation to postimplementation among all groups of youth. Jurisdictions planning to implement plain tobacco packaging should be encouraged by these findings.

How are tobacco smokers using e-cigarettes? Patterns of use, reasons for use and places of purchase in New South Wales.

OBJECTIVES: To explore how and why tobacco smokers and recent quitters in NSW use e-cigarettes, as well as common places of purchase. DESIGN: The Cancer Institute Tobacco Tracking Survey is a serial cross-sectional telephone survey, with 40 interviews in NSW each week. PARTICIPANTS: 2966 tobacco smokers and recent quitters (in the past 12 months) interviewed January 2014 - June 2015. MEASURES: Current e-cigarette use; reasons for using; places of purchase. RESULTS: 9% of the sample reported currently using e-cigarettes; the rate was highest among 18-29-year-old people (16%). Infrequent use (less than weekly; 57%) was more common than frequent use (at least weekly; 43%). Frequent use was more likely among older adults (55 years and older v 18-29 years: adjusted odds ratio [aOR], 4.43; P = 0.002) and less likely among current tobacco smokers (v recent quitters: aOR, 0.38, P = 0.020). The most common reasons for using e-cigarettes by those over 30 years of age was "to help me quit" (42%) and to "cut down" smoking (35%); for younger adults it was "because they are not as bad for your health as cigarettes" (25%). Common places of purchase were the internet (29%) and tobacconists (27%). CONCLUSIONS: Although use of e-cigarettes by tobacco smokers in NSW remains low, some are using e-cigarettes in attempts to reduce tobacco-related harm. Physicians and public health campaigners should inform smokers about the risks associated with dual e-cigarette and tobacco use, advise interested quitters that e-cigarettes are currently unregulated as cessation aids, and continue to provide evidence-based recommendations and cessation services to smokers wanting to quit.

Factors influencing reductions in smoking among Australian adolescents.

A continued increase in the proportion of adolescents who never smoke, as well as an understanding of factors that influence reductions in smoking among this susceptible population, is crucial. The World Health Organization Framework Convention on Tobacco Control provides an appropriate structure to briefly examine Australian and New South Wales policies and programs that are influencing reductions in smoking among adolescents in Australia. This paper provides an overview of price and recent tax measures to reduce the demand for tobacco, the evolution of smoke-free environment policies, changes to tobacco labelling and packaging, public education campaigns, and restrictions to curb tobacco advertising. It also discusses supplyreduction measures that limit adolescents' access to tobacco products. Consideration is given to emerging priorities to achieve continued declines in smoking by Australian adolescents.

Exposure to the 'Dark Side of Tanning' skin cancer prevention mass media campaign and its association with tanning attitudes in New South Wales, Australia.

Melanoma is the most common cancer among 15- to 29-year-olds in Australia, with rates increasing with age. The 'Dark Side of Tanning' (DSOT) mass media campaign was developed in 2007 to influence attitudes related to tanning. This study aimed to assess recall and impact of the DSOT campaign. Data were collected using online surveys of 13- to 44-year-olds living in New South Wales in the summer months of 2007-2010 (n = 7490). Regression models were used to determine predictors of recall of DSOT and to investigate associations between exposure to the campaign and tanning attitudes. The campaign achieved consistently high recall (unprompted recall 42-53% during campaign periods; prompted recall 76-84%). Those who recalled DSOT advertisements had a higher likelihood of reporting negative tanning attitudes compared with those who reported no recall, after adjusting for other factors (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.01-1.27 for unprompted recall; OR 1.19, 95% CI 1.03-1.36 for prompted recall). Being interviewed in later campaign years was also a significant predictor of negative tanning attitudes (e.g. fourth year of campaign versus first year: OR 1.24, 95% CI 1.01-1.53). These results suggest that mass media campaigns have potential to influence tanning-related attitudes and could play an important role in skin cancer prevention.

Out of Sight and Out of Mind? Evaluating the Impact of Point-of-Sale Tobacco Display Bans on Smoking-Related Beliefs and Behaviors in a Sample of Australian Adolescents and Young Adults.

INTRODUCTION: The Australian states of New South Wales (NSW) and Queensland implemented bans on tobacco pack displays at point-of-sale (PoS) in July 2010 and November 2011, respectively. This study evaluated the medium-term impact of the bans on youth. METHODS: Data were drawn from the Tobacco Promotion Impact Study, a repeated cross-sectional survey of youth (12-24 years) in NSW and Queensland conducted yearly 2010-2012 (n = 6,014). Regression analyses examined differences in youth's recall of PoS tobacco displays, smoking-related beliefs, and smoking behaviors in relation to the timing of the PoS display bans. RESULTS: Recall of PoS tobacco displays was significantly less likely for youth interviewed after the bans versus before (OR = 0.45, 95% CI = 0.39, 0.52, p < .01). They were also less likely to report tobacco brand awareness (OR = 0.76, 95% CI = 0.62, 0.92, p < .01), to over-estimate peer smoking (OR = 0.84, 95% CI = 0.74, 0.96, p < .01), or be current smokers (OR = 0.73, 95% CI = 0.55, 0.96, p < .05). Stratified analyses showed that these differences were primarily apparent in the group of youth most likely to be affected by tobacco PoS displays: those who visit tobacco retailers most frequently. After the bans, smokers were less likely to report that they think about smoking as a result of seeing PoS tobacco displays (OR = 0.60, 95% CI = 0.37, 0.97, p < .039). CONCLUSIONS: Our findings suggest an immediate impact of display bans on youth's exposure to tobacco pack displays, and likely impacts on smoking-related outcomes. These results suggest that removing tobacco displays from retail environments can positively contribute to the denormalization of smoking among youth.
