Tobacco Constituents, Flavorants, and Paper Permeability of Factory-Made and Roll-Your-Own Cigarettes on the Australian Market.

INTRODUCTION: Roll-your-own (RYO) tobacco is a popular choice in Australia, with some people who smoke finding these products more attractive than factory-made cigarettes (FMC). Differences in visual and tactile properties and in the feel and taste of the smoke may contribute to this attractiveness. These differences may be driven by variation in tobacco constituents and wrapping paper permeability. However, to date, there has been no comparison of RYO and FMC products on the Australian market. AIMS AND METHODS: Chemical constituents, pH, flavorants, and paper permeability were compared in unburned RYO tobacco and tobacco from FMC. RYO and FMC products from matched brands were compared, as were products from the most popular FMC and RYO brands on the Australian market in 2018. RESULTS: RYO tobacco had higher moisture and humectant content (glycerol and propylene glycol) than FMC tobacco. RYO tobacco also had higher amounts of total and reducing sugars and lower nicotine when comparing the most popular brands. RYO papers were less permeable than FMC papers. Both RYO and FMC tobacco contained many chemicals identified as flavorants, including fourteen with known potential health risks. For most measured constituents and flavorants, RYO tobaccos had more in common with other RYO than FMC, with the commonalities remaining even when matched brands were compared. CONCLUSIONS: Higher levels of moisture, humectants, and sugars in Australian RYO tobacco compared to FMC may be increasing attractiveness of RYO by reducing the harsh taste of the smoke and increasing the moist feel of the tobacco. IMPLICATIONS: While price is the main factor driving the use of RYO tobacco, some people who smoke find these products more attractive. This study has shown that Australian RYO tobacco contains higher amounts of glycerol, propylene glycol, and sugars than FMC. These chemicals may be improving the taste of the tobacco, as well as creating a moist feel that is falsely perceived as indicating that the tobacco is "fresh" and "less chemically." Ironically, it may be that higher amounts of some added chemicals in RYO contribute to false perceptions of a more natural and less harmful product.

Tobacco packaging littering behaviours among Australian adults who smoke: findings from cross-sectional and observational studies to inform the implementation of cigarette pack inserts.

BACKGROUND: Cigarette pack inserts are small cards that highlight the benefits of quitting and promote use of smoking cessation support. With evidence from Canada that they increase self-efficacy to quit, quit attempts and sustained cessation, inserts are set to be introduced into tobacco packs sold in Australia. Some people have expressed concern that the introduction of inserts may create more litter if incorrectly disposed of on pack-opening. METHODS: We used a cross-sectional survey to assess self-reported pack-opening location and waste disposal behaviours of people who smoke to determine the potential for littering to occur when tobacco packs are first opened. We also visited a sample of supermarkets, convenience stores and tobacconists located throughout Melbourne, Australia, to discreetly collect observational data regarding pack-opening and waste disposal behaviours at the point of purchase. RESULTS: Among participants in the cross-sectional study (N=369), the majority reported that they opened their most recent tobacco pack at home (70.9%) where there is little potential for littering, and this proportion was higher among those who smoke daily (78.6%) and men (74.3%). Self-reported behaviours that could result in littering were rare; 1.0% reported that they left tobacco packaging where they believed it would be collected for disposal. Of the 128 individuals observed at the point of purchase across 46 stores, 96.9% did not open the tobacco product immediately after purchase. One incident of littering was observed (0.8%). CONCLUSION: The introduction of cigarette pack inserts in Australia is unlikely to create a substantial amount of additional litter.

Optimising tobacco control campaigns within a changing media landscape and among priority populations.

Reviews published over the past decade confirm tobacco control campaigns can be effective for influencing adult and youth tobacco use behaviours, with strengthening evidence for high cost-effectiveness. Evidence is also accumulating for positive campaign effects on interpersonal discussions, social norms and policy support that can help motivate and sustain quitting and reduce uptake. Research needs over the next decade centre on the rapidly changing media environment and the equity of campaign effects among high smoking prevalence communities. The field needs specific evidence on: how to measure total campaign reach and frequency across the diverse range of media platforms and channels; the optimum mix of traditional, digital and social media to achieve behaviour change, especially among high smoking prevalence communities; the relative reach and impact of the wide variety of integrated, digital and social media message delivery methods; the relative effectiveness of messages that aim to build capacity to quit and optimum methods for combining motivational and capacity-building messages, especially for high prevalence groups who face additional barriers to staying quit; the ongoing effectiveness of traditional versus new versions of messages highlighting tobacco industry practices; the influence of e-cigarette use on tobacco control campaign effects; and the effectiveness of different types of campaigns aiming to prevent e-cigarette uptake and motivate e-cigarette cessation. Research is also needed to investigate the potential for campaigns to influence the public's understanding and support for endgame tobacco control policies and for campaign elements that may influence the social and environmental contexts surrounding smokers that support and maintain behaviour change.

Evidence of cushioning of tobacco tax increases in large retailers in Australia.

BACKGROUND: Tobacco companies may attempt to minimise the impact of tobacco tax increases on consumers by gradually passing on the price rise over several months. This study examined whether there was evidence of large Australian tobacco retailers engaging in this practice (known as cushioning) over a period including both routine indexation and large annual tobacco excise increases. METHODS: Advertised prices of nine factory-made cigarette (FMC) and nine roll-your-own tobacco (RYO) products were recorded from two stores monthly from December 2016 to December 2019. Per cent change in price from the previous month was analysed for FMC and RYO products, controlling for year, month, tobacco company and supermarket chain. RESULTS: Significant main effects of month were observed for FMC and RYO products (both p<0.001). Large, significant average increases in per cent change in price were observed in September for FMC (6.51%) and RYO (11.45%) products, the month of the annual excise increase and prices also significantly increased in October (FMC: 3.01%; RYO: 1.91%). Significant increases were also observed in the months after the March annual routine indexation: by 1.10% in May for FMC products and by 1.09% in April for RYO products. CONCLUSION: This study has demonstrated evidence of cushioning of tax increases of FMC and RYO products in large Australian supermarkets. The monthly per cent change in price significantly increased several months after routine excise indexation and in the 2 months following a large annual excise increase. Further research with a larger sample of products and stores is needed to confirm these findings.

Public support for policies to phase out the retail sale of cigarettes in Australia: results from a nationally representative survey.

BACKGROUND: There is growing international interest in a goal once considered unthinkable: phasing out the retail sales of smoked tobacco products. In this study, we examined public support for phasing out sales and specific measures for moving towards a phase-out among a nationally representative sample of Australian adults. METHODS: In December 2019, we used a probability-based online panel, Life in Australia™, to survey n=1939 Australian adults (n=1874 included in analyses due to missing data). RESULTS: Almost two-thirds of respondents thought it would be 'a good thing' if there came a time when it was no longer legal to sell cigarettes in shops in Australia and only 16.7% thought it would be 'a bad thing'. After the concept of a phase-out was defined as removing a product from the Australian market over a set period, such as 5 years, but still allowing purchases online from overseas companies, 50.7% indicated support for such a phase-out and 61.8% thought it should happen within 10 years. Support was greater for specific measures such as licensing tobacco retailers (75.3%) and restricting sales to places children cannot enter (76.3%). Support tended to be consistent across demographic subgroups but was stronger among never and former smokers than among current smokers. CONCLUSIONS: There has been little public discussion in Australia about the goal of 1 day phasing out the retail sale of cigarettes. It is notable that such policies are reasonably well supported by the Australian public, with only minority opposition.

Are anti-smoking social norms associated with tobacco control mass media campaigns, tax and policy changes? Findings from an Australian serial cross-sectional population study of smokers.

BACKGROUND: Anti-smoking social norms are associated with subsequent quitting behaviours. We examined if exposure to tobacco control advertisements and policy changes predict subjective (perceived disapproval of smoking among close family and friends) and internalised injunctive norms (embarrassed about telling others you are a smoker). METHODS: A serial cross-sectional population survey of Australian adult smokers (n=6649; 2012 to 2015). Logistic regression analyses examined associations of social norms with exposure to different types of tobacco control advertisements, tax increases and other tobacco control policies, adjusting for key demographic, smoking and media exposure covariates. Interaction analyses examined differences by age and socioeconomic status (SES). RESULTS: Greater past month exposure to predominantly fear-evoking advertisements was associated with increased odds of perceiving disapproval (per 1000 gross rating points: adjusted OR (AOR) 2.69, 95% CI: 1.34 to 5.39), while exposure to advertisements evoking multiple negative emotions (fear, guilt, sadness) reduced perceived disapproval (AOR 0.61, 95% CI: 0.42 to 0.87). Increased perceived disapproval was also associated with anticipation (AOR 1.38, 95% CI: 1.02 to 1.88), and implementation of a series of annual 12.5% tobacco tax rises (AOR 1.41, 95% CI: 1.03 to 1.94). Associations were consistent across age and SES. There were no associations nor subgroup interactions between advertisement exposure or policy changes and feeling embarrassed about telling others you are a smoker. CONCLUSION: Smokers' perceptions of family and friends' disapproval of their smoking was more common after exposure to fear-evoking tobacco control campaigns and after large tobacco tax increases were announced and implemented.

Australian smokers' experiences and perceptions of recessed and firm filter cigarettes.

BACKGROUND: While cigarette filter modifications have long been used to increase product appeal and assuage health concerns, tighter marketing restrictions, including plain packaging, have further spurred the growth of filter variants. We explored and assessed experiences and perceptions of smokers who had tried and/or currently use recessed filter cigarettes (RFCs) and firm filter cigarettes (FFCs). METHOD: In November 2018, we undertook eight exploratory focus groups of Australian adult factory-made cigarette smokers (total n=56). In July 2019, we surveyed 999 smokers aged 18-69 years to quantify ever and current use of these products and associated beliefs and sensory experiences. RESULTS: Focus group and survey findings were consistent. Among 988 smokers who had at least tried factory-made cigarettes, 28.9% had tried FFCs and 11.1% currently smoked these, while 36.4% had tried RFCs and 7.5% currently smoked these. Smokers in both studies believed these filters may reduce harm and that FFCs increase appeal. In the survey, 58.9% of RFC triers agreed these hide the filter's brown stain and 48.9% agreed that RFCs keep harmful substances away from the mouth. Similarly, 58.4% of FFC triers agreed these trap more harmful substances than standard filters. Relative to standard filter cigarettes, more smokers experienced FFCs and RFCs as feeling clean (p=0.03) and more current FFC users experienced these as feeling smooth (p=0.01). CONCLUSION: RFCs and FFCs undermine plain packaging legislation, which aims to reduce appeal and minimise misperceptions about the relative harms of different tobacco products. Like other filter modifications, these filter variants should be disallowed.

Indexation of Tobacco Excise and Customs Duty and Smoking Prevalence Among Australian Adults, 2001-2010: A Serial Cross-sectional Study.

INTRODUCTION: Australia's excise and customs duty on tobacco has been automatically increased biannually since 1984. Increases in duty on par with inflation ensured that tobacco stayed at least as costly as other goods. This would be expected to maintain, rather than drive down, smoking prevalence. We examined the association between smoking prevalence and duty over a 10-year period. METHODS: Using monthly data from five Australian capital cities, collected from March 2001 to March 2010 among Australians aged at least 18 years, multiple linear regression modeled associations between smoking prevalence and the two components (duty and non-duty) of the recommended retail price of an average packet of cigarettes, adjusting for policy covariates. RESULTS: Prevalence declined from 23.6% in March 2001 to 17.0% in March 2010 [absolute difference 6.6%; 95% confidence interval (CI) = 6.5 to 6.8]. Duty increased from $0.2026 to $0.2622 per cigarette over the same period. In the adjusted model, a 1-cent increase in the duty component of price was not associated with changes in prevalence (0.019; 95% CI = -0.035 to 0.028). Increased non-duty component of price was associated with a decline in prevalence (-0.027; 95% CI = -0.052 to -0.002). This effect was stronger when changes in income were controlled for. CONCLUSIONS: In line with expectations, inflation-adjusted duty was not associated with changes in smoking prevalence, but it may have prevented upward pressure on prevalence that increasing affordability could have exerted. Frequent increases in duty greater than the growth in both wages and goods would more effectively reduce smoking than regular indexation. IMPLICATIONS: Few countries inflation-adjusted excise duty to ensure that tobacco products do not become more affordable; however, Australia experienced a decade of inflation adjustment alone, enabling the impact of this policy to be studied. This study shows that inflation-adjusted duty likely did prevent tobacco becoming more affordable and that indexation was associated with declines in smoking when tobacco companies over-shifted the duty rises (ie, increased price over and above duty rises).The study also suggests that frequent increases in taxation that exceed both wage growth and increases in costliness of other goods are needed to prompt increased rates of quitting.

Long-term impact of plain packaging of cigarettes with larger graphic health warnings: findings from cross-sectional surveys of Australian adolescents between 2011 and 2017.

OBJECTIVE: To assess the long-term impact of plain packaging (PP) of cigarettes with larger graphic health warnings (HW) introduced in December 2012 on adolescents' relevant tobacco-related perceptions. METHODS: Cross-sectional school-based surveys of 12 to 17 year olds in 2011 (n=4413), 2013 (n=4423), 2014 (n=4576) and 2017 (n=4266). Students rated the character of four popular cigarette brands, indicated their agreement regarding brand differences in smoking ease, quitting, addictiveness, harmfulness and pack attractiveness and positive/negative perceptions of pack image. The frequency of students reading, attending to, thinking and talking about HW was assessed. Responses of students seeing cigarette packs in the previous 6 months (2011: 63%; 2013: 67%, 2014: 56%, 2017: 56%) were examined. RESULTS: Smoking prevalence declined from 2011 to 2017. Among students who had recently seen packs, cigarette packs were rated less positively and more negatively in 2017 than in 2011 (p<0.001) with ratings similar between 2013 and 2017. Positive character ratings for each brand reduced between 2011 and 2013 (ps<0.05) with further reductions between 2013 and 2017 (ps<0.05). Fewer students agreed, and more were uncertain, that brands differed in their smoking ease, addictiveness, harmfulness and pack attractiveness in 2017 than 2011. The frequency of students reading, attending, talking or thinking about HW did not change between 2011 and 2017. CONCLUSIONS: PP's initial impact in reducing adolescent's positive perceptions of cigarette packs and brand differences continued in the following years with tobacco packaging less appealing to young people in 2017 than 2011 and students more uncertain about brand differences.

Who uses rollies? Trends in product offerings, price and use of roll-your-own tobacco in Australia.

OBJECTIVE: We examined the roll-your-own (RYO) tobacco product market in Australia from 2001 to 2016. Trends in use of RYO tobacco among Australian adults were examined for 2004-2016. METHODS: Changes in brand availability, pouch sizes and lowest priced products were noted from trade magazines. Prevalence of smoking of RYO and factory-made (FM) cigarettes among those 18 years and older was obtained from five consecutive waves of a large (n>21 000) nationally representative triennial survey from 2004 to 2016. Trends in cigarette use were examined using logistic regression. RESULTS: Changes in the Australian RYO market from 2001 to 2016 included a doubling in the number of brands, progressively smaller pouch sizes with smaller increases in price than in traditional RYO and comparable FM products. While use of FM cigarettes declined between 2004 and 2016, the proportion of adults exclusively using RYO tobacco linearly increased with each survey wave (OR 1.03, 95% CI 1.02 to 1.05, p<0.001), from 1.2% in 2004 to 1.7% in 2016. Exclusive RYO use among current smokers increased more among females than males, and young adults compared with those aged 30 years or older, but did not differ by socioeconomic status. CONCLUSIONS: In contrast to substantial declines in FM cigarette use, exclusive use of RYO cigarettes increased in Australians since 2004, particularly among females and young adults. This has corresponded to a period of substantial changes to the RYO market, including progressively smaller and relatively more affordable products. Policy action to reduce price-related marketing and correct consumer misinformation about RYO tobacco are urgently required.

Hardening or softening? An observational study of changes to the prevalence of hardening indicators in Victoria, Australia, 2001-2016.

BACKGROUND: The hardening hypothesis predicts that as smoking prevalence declines, remaining smokers will be more heavily addicted to nicotine and/or less interested in quitting. We tested this hypothesis in a population exposed to a comprehensive tobacco control programme over a 16-year period. METHODS: Annual cross-sectional surveys randomly sampled adults (aged 26+) in the state of Victoria, Australia, between 2001 and 2016. Until 2010, participants were recruited through random digit dialling to landline telephones; from 2011, sampling frames also included mobile phones. Logistic regressions assessed changes over time in the prevalence of smoking and each hardening indicator; additional models examined interactions by sex, age, education and socioeconomic status. RESULTS: Smoking prevalence declined significantly between 2001 and 2016 (20.1%-13.0%), as did the prevalence of seven hardening indicators: daily smoking, heavy consumption, no quit attempt in the past 5 years or past 12 months, no intention to quit in the next 6 months or next 30 days, and happiness to keep smoking. In addition, the proportion of smokers defined as 'hardcore' decreased from 17.2% to 9.1%. On the whole, hardening indicators decreased to a similar extent among demographic subgroups. CONCLUSIONS: These results are inconsistent with the hardening hypothesis. Rather, they suggest that a comprehensive tobacco control programme that combines provision of cessation support to individual smokers with implementation of population-level interventions to drive all smokers towards quitting, can successfully reduce both smoking prevalence and levels of dependence and desire to keep smoking among the remaining population of smokers.

Observed smoking and tobacco pack display in Australian outdoor cafés 2 years after implementation of plain packaging.

Background: Implementation of tobacco plain packaging (PP) in Australia in December 2012 was associated with significant reductions in the percentage of patrons at outdoor cafés observed to be displaying tobacco packs and actively smoking, immediately post-implementation and 1 year later. This study examines whether these positive effects were sustained through to 2 years post-PP. Methods: An observational study conducted at cafés, restaurants and bars with outdoor seating in Melbourne, Australia documented the number of: patrons; patrons actively smoking; tobacco packs on display; orientation and type of displayed packs and whether or not children were present. Data were collected pre-PP (2012), early post-PP (2013), 1 year post-PP (2014) and 2 years post-PP (2015). Multilevel Poisson regressions analyzed changes in each outcome, adjusting for important covariates. Results: Overall, positive effects of PP implementation on tobacco pack display and active smoking were not fully sustained through to 2 years post-PP for the total sample. Interactions between phase and the presence of children indicated that pack display and active smoking were lower in all post-implementation phases (compared with pre-PP) at venues where children were present but not at venues where children were not present. Conclusions: Children at outdoor cafés were still being exposed to less tobacco packaging and active smoking, 2 years after implementation of the packaging changes. More regular refreshment of graphic health warnings is likely to be required to sustain these effects, and to reduce pack display behaviour at venues with no children.

Alcohol harm reduction advertisements: a content analysis of topic, objective, emotional tone, execution and target audience.

BACKGROUND: Public health mass media campaigns may contribute to reducing the health and social burden attributed to alcohol consumption, but little is known about which advertising characteristics have been used, or have been effective, in alcohol harm reduction campaigns to date. As a first step towards encouraging further research to identify the impact of various advertising characteristics, this study aimed to systematically identify and examine the content of alcohol harm reduction advertisements (ads). METHOD: Ads were identified through an exhaustive internet search of Google, YouTube, Vimeo, and relevant government and health agency websites. Eligible ads were: English language, produced between 2006 and 2014, not primarily focused on drink-driving or alcohol in pregnancy, and not alcohol industry funded. Systematic content analysis of all ads was performed; each ad was double-coded. RESULTS: In total, 110 individual ads from 72 different alcohol harm reduction campaigns were identified, with the main source countries being Australia (40%) and the United Kingdom (26%). The dominant topic for 52% of ads was short-term harms, while 10% addressed long-term harms, 18% addressed underage drinking, 17% communicated a how-to-change message, and 3% advocated for policy change. The behavioural objective of most ads was to motivate audiences to reduce their alcohol consumption (38%) or to behave responsibly and/or not get drunk when drinking (33%). Only 10% of all ads mentioned low-risk drinking guidelines. Eighty-seven percent of ads used a dramatisation execution style and 74% had a negative emotional tone. Ninety percent of ads contained messages or content that appeared to target adults, and 36% specifically targeted young adults. CONCLUSIONS: Some message attributes have been employed more frequently than others, suggesting several promising avenues for future audience or population-based research to compare the relative effectiveness of different characteristics of alcohol harm reduction ads. Given most alcohol-attributable harm is due to long-term disease, these findings suggest future campaigns may fill a potentially important gap if they were to focus on long-term harms. There is scope for such long-term harm campaigns to place greater emphasis on encouraging reduced personal consumption of alcohol, potentially through more frequent communication of low-risk drinking guidelines.

Talking About Antismoking Campaigns: What Do Smokers Talk About, and How Does Talk Influence Campaign Effectiveness?

Campaign-stimulated conversations have been shown to increase the effectiveness of antismoking campaigns. In order to explore why such effects occur, in the current study we coded the content of naturally occurring conversations. We also examined whether the short-term effects of talking, and of different types of talk, on quitting intentions were mediated through intrapersonal message responses. Using the Natural Exposure(SM) methodology, we exposed 411 smokers to 1 of 6 antismoking advertisements while they were watching television at home. Responses to the advertisement-conversation participation and content, emotional responses, personalized perceived effectiveness, and changes in intentions to quit-were measured within 3 days of exposure. Conversations were coded for appraisal of the advertisement (favorable, neutral, or unfavorable) and the presence of quitting talk and emotion talk. Mediation analyses indicated that the positive effects of talking on intention change were mediated through personalized perceived effectiveness and that the positive effects were driven by conversations that contained a favorable appraisal and/or quitting talk. Conversely, conversations that contained an unfavorable appraisal of the advertisement were negatively associated with campaign effectiveness. These findings highlight the importance of measuring interpersonal communication when evaluating campaigns and the need for further research to identify the message characteristics that predict when smokers talk and when they talk only in desirable ways.

"You're made to feel like a dirty filthy smoker when you're not, cigar smoking is another thing all together." Responses of Australian cigar and cigarillo smokers to plain packaging.

OBJECTIVE: To explore experiences of cigar and cigarillo smokers under Australian laws requiring plain packaging (PP) and strengthened graphic health warnings (GHWs). METHODS: In February/March 2014, we conducted: in-depth interviews with 10 regular premium cigar smokers; two focus groups with occasional premium cigar and premium cigarillo smokers (n=14); four focus groups with non-premium cigarillo smokers (n=28); and a national online survey of cigar and/or cigarillo smokers (n=268). RESULTS: Premium cigar smokers had limited exposure to PP, with many purchasing fully branded cigars in boxes duty free or online and singles in non-compliant packaging. Those who were exposed noticed and were concerned by the warnings, tried to avoid them and felt more like 'dirty smokers'. Changes in perceived taste, harm and value were minimal for experienced premium cigar smokers. Occasional premium cigar and premium cigarillo smokers with higher PP exposure (gained by purchasing boxes rather than singles) perceived cigar/package appeal and value had declined and noticed the GHWs. Non-premium cigarillo smokers reported high PP exposure, reduced perceived appeal, quality, taste, enjoyment and value, somewhat increased perceived harm, greater noticeability of GHWs and concealment of packs and more contemplation of quitting. Online survey participants reported increased noticeability of GHWs (33%), decreased appeal of packaging (53%) and reduced consumption of cigars (42%) and cigarillos (44%) since PP implementation. CONCLUSIONS: Non-premium cigarillo smokers appear to have been most exposed and influenced by PP, with cigar smokers less so, especially regular premium cigar smokers who have maintained access to fully branded products.

What is the role of tobacco control advertising intensity and duration in reducing adolescent smoking prevalence? Findings from 16†years of tobacco control mass media advertising in Australia.

OBJECTIVE: To examine how the intensity and duration of tobacco control advertising relate to adolescent smoking prevalence. METHODS: Australian students (aged 12-17 years) participating in a national survey conducted triennially between 1993 and 2008 (sample size range 12 314-16 611). The outcome measure was students' smoking in the previous 4 weeks collected through anonymous, self-completed surveys. For each student, monthly targeted rating points (TRPs, a measure of television advertising exposure) for tobacco control advertising was calculated for the 3 and 12 months prior to surveying. For each time period, cumulative TRPs exposure and exposure to three intensity levels (≥100 TRPs/month; ≥400 TRPs/month; ≥800 TRPs/month) over increasing durations (eg, 1 month, 2 months, etc) were calculated. Logistic regression examined associations between TRPs and adolescent smoking after controlling for demographic and policy variables. RESULTS: Past 3-month cumulative TRPs were found to have an inverse relationship with smoking prevalence. Low TRPs exposure in the past 12 months was positively associated with adolescent smoking prevalence. However, smoking prevalence reduced with cumulative exposure levels above 5800 cumulative TRPs. Additionally, exposure to ≥400 TRPs/month and ≥800 TRPs/month were associated with reduced likelihood of smoking, although the duration needed for this effect differed for the two intensity levels. When intensity was ≥400 TRPs/month, the odds of smoking only reduced with continuous exposure. When intensity was ≥800 TRPs/month, exposure at levels less than monthly was associated with reductions in smoking prevalence. CONCLUSIONS: Both antismoking advertising intensity and duration are important for ensuring reductions in adolescent smoking prevalence.

Time series analysis of the impact of tobacco control policies on smoking prevalence among Australian adults, 2001-2011.

OBJECTIVE: To determine the impact of tobacco control policies and mass media campaigns on smoking prevalence in Australian adults. METHODS: Data for calculating the average monthly prevalence of smoking between January 2001 and June 2011 were obtained via structured interviews of randomly sampled adults aged 18 years or older from Australia's five largest capital cities (monthly mean number of adults interviewed: 2375). The influence on smoking prevalence was estimated for increased tobacco taxes; strengthened smoke-free laws; increased monthly population exposure to televised tobacco control mass media campaigns and pharmaceutical company advertising for nicotine replacement therapy (NRT), using gross ratings points; monthly sales of NRT, bupropion and varenicline; and introduction of graphic health warnings on cigarette packs. Autoregressive integrated moving average (ARIMA) models were used to examine the influence of these interventions on smoking prevalence. FINDINGS: The mean smoking prevalence for the study period was 19.9% (standard deviation: 2.0%), with a drop from 23.6% (in January 2001) to 17.3% (in June 2011). The best-fitting model showed that stronger smoke-free laws, tobacco price increases and greater exposure to mass media campaigns independently explained 76% of the decrease in smoking prevalence from February 2002 to June 2011. CONCLUSION: Increased tobacco taxation, more comprehensive smoke-free laws and increased investment in mass media campaigns played a substantial role in reducing smoking prevalence among Australian adults between 2001 and 2011.

Assessing the effectiveness of antismoking television advertisements: do audience ratings of perceived effectiveness predict changes in quitting intentions and smoking behaviours?

BACKGROUND: Decisions about which antismoking advertisements should be aired are often guided by audience ratings of perceived effectiveness (PE). Given that the usefulness of PE measures depends on their ability to predict the likelihood that a message will have a positive impact on outcomes such as behaviour change, in the current study we used pre-exposure, postexposure and follow-up measures to test the association between PE and subsequent changes in quitting intentions and smoking behaviours. METHODS: Daily smokers (N=231; 18 years and older) completed baseline measures of quitting intentions before watching an antismoking advertisement. Immediately following exposure, intentions were measured again and PE was measured using six items that factored into two scales: ad-directed PE (ADPE) and personalised PE (PPE). A follow-up telephone survey conducted within 3 weeks of exposure measured behaviour change (reduced cigarette consumption or quit attempts). RESULTS: From pre-exposure to postexposure, 18% of smokers showed a positive change in their intentions. Controlling for baseline intentions, PPE independently predicted intention change (OR=2.57, p=0.004). At follow-up, 26% of smokers reported that they had changed their behaviour. PPE scores also predicted the likelihood of behaviour change (OR=1.93, p=0.009). CONCLUSIONS: Audience ratings of PPE, but not ADPE, were found to predict subsequent intention and behaviour change. These findings increase confidence in the use of PE measures to pretest and evaluate antismoking television advertisements, particularly when these measures tap the extent to which a smoker has been personally affected by the message.

The silent salesman: an observational study of personal tobacco pack display at outdoor café strips in Australia.

OBJECTIVE: We sought to determine the relative frequency and nature of personal display of cigarette packs by smokers in two Australian cities where 30% front-of-pack and 90% back-of-pack health warnings have been used since 2006 and comprehensive tobacco marketing restrictions apply. METHODS: An observational study counted patrons, active smokers and tobacco packs at cafés, restaurants and bars with outdoor seating. Pack orientation and use of cigarette cases were also noted. RESULTS: Overall, 18954 patrons, 1576 active smokers and 2153 packs were observed, meaning that one out of every 12.0 patrons was actively smoking, and one of every 8.8 patrons displayed a pack. Packs were more frequently observed in lower socio-economic neighbourhoods, reflecting the higher prevalence of smoking in those regions. Packs were displayed less often in venues where children were present, suggesting a greater tendency not to smoke around children. Most packs (81.4%) were oriented face-up, permitting prominent brand display. Only 1.5% of observed packs were cigarette cases, and 4.2% of packs were concealed by another item, such as a phone or wallet. CONCLUSIONS: Tobacco packs are frequently seen on table-tops in café strips, providing many opportunities for other patrons and passers-by to be incidentally exposed to cigarette brand names and imagery. Use of cigarette cases is rare, suggesting that smokers eventually habituate to pictorial warnings on branded packs and/or find repeated decanting of each newly purchased branded pack into a case to be inconvenient.
