Abstract

Study objectives: To compare the prices paid for nicotine vaping products (NVPs) and supplies among current NVP users to prices paid for cigarettes among current smokers.

Data: The 2016 International Tobacco Control Four Country Vaping and Smoking Survey (4CV1). Key measures included: (1) self-reported prices paid for reusable NVPs (eg, rechargeable devices with cartridges and tank system devices with e-liquids) in the 3-month period prior to the survey among current NVP users, (2) prices paid for disposable NVPs, cartridges and e-liquids purchased in the last 30 days among current NVP users and (3) self-reported prices paid for cigarettes among current smokers.

Results: Disposable NVP price was higher than the price of a comparable unit for combustible cigarettes in England (EN), USA and Canada (CA). Prefilled cartridge price was higher than the price of a comparable unit of cigarettes in USA and CA, but lower in EN and Australia. E-liquid price was consistently lower than the price of a comparable unit of cigarettes across four countries. For start-up costs, price of a rechargeable device is approximately 3–5 times higher than a pack of cigarettes in four countries.

Conclusion: NVP prices were generally higher than prices of combustible cigarettes, especially the high upfront NVP devices. The high upfront costs of purchasing a reusable NVP may discourage some smokers from switching to vaping. However, the average lower costs of cartridges and e-liquids relative to a package of cigarettes make switching to a NVP an attractive alternative to smoking in the long term so long as smokers switch completely to vaping.

Identifying factors that conjointly influence nicotine vaping product relative harm perception among smokers and recent ex-smokers: Findings from the 2016 ITC Four Country Smoking and Vaping Survey. Drug and Alcohol Dependence, 218, 108370.

Abstract

Background: Use of nicotine vaping products (NVPs) to replace smoking is often influenced by perceived harmfulness of these products relative to smoking. This study aimed to identify factors that conjointly influenced NVP relative harm perception among smokers and ex-smokers.

Methods: Data (n = 11,838) from adult smokers and ex-smokers (quit < 2 years) who participated in the 2016 ITC 4 Country Smoking and Vaping Surveys in Australia, Canada, England and the US were analyzed. Decision tree models were used to classify respondents into those who perceived vaping as less harmful than smoking (correct perception) versus otherwise (incorrect perception) based on their socio-demographic, smoking and vaping related variables.

Results: Decision tree analysis identified nicotine replacement therapy (NRT) harmfulness perceptions relative to smoking, perceived vaping portrayal in the media and other sources as positive, negative or balanced, recency of seeking online vaping information, and age as the key variables that interacted conjointly to classify respondents into those with correct versus incorrect harm perceptions of vaping relative to smoking (model performance accuracy = 0.70-0.74). In all countries, NRT relative harmfulness perception and vaping portrayal perception were consistently the two most important classifying variables, with other variables showing some country differences.

Conclusions: In all four countries, perception of NVP relative harmfulness among smokers and recent ex-smokers is strongly influenced by a combination of NRT relative harmfulness perception and vaping portrayal in the media and other sources. These conjoint factors can serve as useful markers for identifying subgroups more vulnerable to misperception about NVP relative harmfulness to benefit from corrective intervention.

Abstract

Importance Use of e-cigarettes increased among adolescents between 2011 and 2019. However, whether these changes are affecting patterns of use of other tobacco products, especially cigarettes, remains unclear.

Objective To examine the long-term and recent trends in cigarette smoking and smokeless tobacco product use among US adolescents by grade (8th, 10th, and 12th), sex (male and female), and race (White and Black).

Design, Setting, and Participants In this cross-sectional study, joinpoint regression analyses were performed to characterize trends in tobacco product use for key sociodemographic groups, identifying change of trend years (joinpoints). Students in the 8th, 10th, and 12th grades at US secondary schools and high schools who participated in the nationally representative Monitoring the Future survey from January 7, 1991, to June 3, 2019, were evaluated.

Exposures Cigarette smoking and smokeless tobacco product use during the past 30 days.

Main Outcomes and Measures Past 30-day and daily prevalence of cigarette smoking and smokeless tobacco product use by year, grade, sex, and race. The prevalence trend segments, change of trend years (joinpoints), and annual percentage change (APC) in prevalence within each trend segment were estimated using joinpoint regression.

Results Since 1991, 487 335 8th-grade, 447 310 10th-grade, and 424 236 12th-grade students have completed the Monitoring the Future survey (including 663 663 girls and 632 698 boys [those who did not respond to the sex question in the survey were excluded from the sex analyses]). Past 30-day and daily smoking prevalence increased in all groups analyzed from 1991 until 1996 and 1997 and has been decreasing ever since, with more rapid reductions in recent years. For example, daily smoking among 12th-grade boys increased at an APC of 4.9% (95% CI, 3.5%-6.3%) from 1991 to 1998, decreased at an APC of −8.0% (95% CI, –9.3% to –6.7%) from 1998 to 2006, decreased at an APC of −1.6% (95% CI, –4.6% to 1.5%) from 2006 to 2012, and decreased at an APC of −17.4% (95% CI, –19.4% to –15.4%) from 2012 to 2019. Similar results were observed for boys in the 8th grade (5.0% [95% CI, 0.1%-10.2%] for 1991-1996, –8.8% [95% CI, –10.0% to –7.6%] for 1996-2011, and –17.3% [95% CI, –22.2% to –12.0%] for 2011-2019) and 10th grade (7.1% [95% CI, 3.7%-10.7%] for 1991-1997, –11.1% [95% CI, –13.9% to –8.2%] for 1997-2005,–0.7% [95% CI, –5.9% to 4.9%] for 2005-2011, and −17.9 [95%, –21.7% to –13.9%] for 2011-2019), for girls in 8th grade (10.9% [95% CI, 5.0%-17.2%] for 1991-1996 and –10.8% [95% CI, –11.7% to –10.0% for 1996-2019), 10th grade (7.2% [95% CI, 3.9%-10.7%] for 1991-1997, –9.5% [95% CI, –10.5% to –8.6%] for 1997-2012, and –16.3% [95% CI, –21.8% to –10.4%] for 2012-2019), and 12th grade (6.5% [95% CI, 3.6%-9.5%] for 1991-1997, –7.2% [95% CI, –8.1% to –6.3%] for 1997-2012, and –17.5% [95% CI, –21.2% to –13.6%] for 2012-2019). Results were similar, too, for Black adolescents (2015-2019 average annual percentage change: –8.6% [95% CI, –10.3% to –6.8%] for 8th graders; –17.7% [95% CI, –26.3% to –8.2%] for 10th graders; and –18.3% [95% CI, –23.9% to –12.2%] for 12th graders) and White adolescents (2015-2019 average annual percentage change: –17.3% [95% CI, –20.6% to –13.7%] for 8th graders; –16.9% [95% CI, –20.5% to –13.2%] for 10th graders; and –17.0% [95% CI, –20.5% to –13.2%] for 12th graders). Smokeless tobacco was used more variably through 2012, followed by consistent decreases in the past 5 years. For instance, smokeless tobacco use in the past 30 days in 10th-grade boys decreased at an APC of –6.5% (95% CI, –7.5% to –5.4%) from 1991 to 2004, increased at an APC of 3.1% (95% CI, –0.8% to 7.1%) from 2004 to 2012, and decreased at an APC of –11.6% (95% CI, –15.7% to –7.4%) from 2012 to 2019. Similarly, daily smokeless tobacco use in 12th-grade boys decreased at an APC of –3.8% (95% CI, –5.4% to –2.1%) from 1992 to 2005, increased at an APC of 3.1% (95% CI, –0.2% to 6.5%) from 2005 to 2015, and decreased at an APC of –23.0% (95% CI, –33.3% to –11.0%) from 2015 to 2019.

Conclusions and Relevance This cross-sectional study suggests that, despite the increase in the prevalence of e-cigarette use among adolescents between 2011 and 2019, the prevalence of cigarette and smokeless tobacco use has decreased more rapidly during the same period compared with earlier years.

Self-reported exposure to secondhand smoke and support for complete smoking bans in multiunit housing among smokers from the United States, Canada, and the United Kingdom. Preventing Chronic Disease, 17, E147

Abstract

Introduction

Involuntary exposure to secondhand smoke most frequently occurs at home, which is problematic for residents of multiunit housing (MUH). The primary objective of this study was to estimate the extent of secondhand smoke incursions into the homes of MUH smokers who banned smoking in their homes but lived in buildings where smoking is allowed.

Methods

We used data from Wave 9 of the International Tobacco Control Four Country Survey. We estimated 1) the prevalence of complete smoking bans among smokers living in single-family homes vs MUH in the United States (n = 3,208), Canada (n = 1,592), and the United Kingdom (n = 1,403) from 2013 to 2015; 2) the extent of secondhand smoke incursions into the homes of MUH smokers who banned smoking in their units but lived in buildings that allow smoking; and 3) MUH smokers’ preferences for complete smoking bans in MUH. Weighted multivariable logistic regression estimated the country-specific adjusted prevalence of all outcomes.

Results

Overall, 53.0% of smokers living in single-family homes completely banned smoking in their homes, compared with 44.8% of smokers in MUH. Across all 3 countries, only 27.8% of MUH smokers reported that smoking was completely prohibited in their building. A similar percentage of MUH smokers who banned smoking in their home but lived in buildings allowing smoking reported a secondhand smoke incursion into their home in the United States (29.9%; 95% CI, 20.4%–41.5%), Canada (38.4%; 95% CI, 26.7%–51.6%), and the United Kingdom (24.7%; 95% CI, 15.7%–36.7%). Across all 3 countries, 36.1% (95% CI, 33.4%–38.9%) of smokers in MUH reported they preferred a complete smoking ban in all building areas.

Conclusion

A need remains to educate MUH operators and residents about the benefits of comprehensive smoke-free policies.

Awareness of marketing of heated tobacco products and cigarettes and support for tobacco marketing restrictions in Japan: Findings from the 2018 International Tobacco Control (ITC) Japan Survey. International Journal of Environmental Research and Public Health, 17(22), 8418.

Abstract

Japan is one of the world's largest cigarette markets and the top heated tobacco product (HTP) market. No forms of tobacco advertising, promotion, and sponsorship (TAPS) are banned under national law, although the industry has some voluntary TAPS restrictions. This study examines Japanese tobacco users' self-reported exposure to cigarette and HTP marketing through eight channels, as well as their support for TAPS bans. Data are from the 2018 ITC Japan Survey, a cohort survey of adult exclusive cigarette smokers (n = 3288), exclusive HTP users (n = 164), HTP-cigarette dual users (n = 549), and non-users (n = 614). Measures of overall average exposure to the eight channels of cigarette and HTP advertising were constructed to examine differences in exposure across user groups and products. Dual users reported the highest exposure to cigarette and HTP advertising. Tobacco users (those who used cigarettes, HTPs, or both) reported higher average exposure to HTP compared to cigarette advertising, however non-users reported higher average exposure to cigarette compared to HTP advertising. Retail stores where tobacco or HTPs are sold were the most prevalent channel for HTP and cigarette advertising, reported by 30-43% of non-users to 66-71% of dual users. Non-users reported similar exposure to cigarette advertising via television and newspapers/magazines as cigarette smokers and dual users; however, advertising via websites/social media was lower among non-users and HTP users than among cigarette smokers and dual users (p < 0.05). Most respondents supported a ban on cigarette (54%) and HTP (60%) product displays in stores, and cigarette advertising in stores (58%).

Abstract

In this paper we have attempted to identify missed opportunities to change the trajectory of smoking and smoking caused diseases in America over the past 100 years. Many of the missed opportunities identified are due to the actions of cigarette manufacturers who misled the public about the dangers of cigarette smoking, the addictiveness of nicotine, and the feasibility of providing lower risk alternative nicotine delivery products to addicted smokers. An important lesson learned from the past is that treating all tobacco/nicotine products as equivalently harmful is counterproductive to public health as it only serves to protect the most lethal nicotine product - cigarettes. Since 2000, the evolving marketplace of lower risk nicotine products combined with regulatory authority over tobacco products represents a new opportunity to dramatically transform the cigarette business in ways that were never imagined when the war on tobacco was raging decades ago. However, this requires embracing risk-proportionate regulation, taxation policies, and providing consumers with accurate public messaging on product relative risks. A regulatory framework based on sound science that encourages and rewards new or existing manufacturers to invest in consumer acceptable lower risk products to replace cigarettes needs to be encouraged. The past is indeed not the future in smoking control, but it may be difficult to escape the past unless a realignment of market forces and policies can be achieved.

Reasons for regularly using heated tobacco products among adults current and former smokers in Japan: Findings from 2018 ITC Japan Survey. International Journal of Environmental Research and Public Health, 17(21), 8030.

Abstract

The market growth of heated tobacco products (HTPs), such as IQOS, Ploom TECH, and glo, has increased dramatically in Japan since 2016. Little is known about the reasons why current and former smokers are using HTPs. The data for this cross-sectional study were from the 2018 (Wave 1) International Tobacco Control (ITC) Japan Survey, a national web-based survey of 4500 people, including 658 current HTP users, of whom 549 were concurrently smoking cigarettes and 109 were former smokers. The most common reasons for regularly using HTPs were: beliefs that HTP are less harmful than cigarettes to themselves (90.6%) or to others (86.7%), enjoyment (76.5%), and social acceptability (74.4%). About half of current smokers (55.1%) reported using HTPs because these products might help them quit smoking. However, a near-equal percentage (52.0%) of current smokers reported using HTPs to replace some of the cigarettes they smoked so that they did not have to give up smoking altogether. If smokers are using HTPs to complement rather than quit their smoking, then the harm reduction potential of HTPs suggested by the toxicity studies will be diminished.

Nicotine and Tobacco Research, 22(10), 1831-1841.

Abstract

Introduction: This study examined whether non-tobacco flavors are more commonly used by vapers (ecigarette users) compared to tobacco flavor, described which flavors are most popular, and tested whether flavors are associated with: vaping satisfaction relative to smoking, level of enjoyment with vaping, reasons for using e-cigarettes, and making an attempt to quit smoking by smokers.

Methods: This cross sectional study included 1,603 adults from Canada and the US who vaped at least weekly, and were either current smokers (concurrent users) or former smokers (exclusive vapers). Respondents were categorized into one of seven flavors they used most in the last month: tobacco, tobacco-menthol, unflavored, or one of the non-tobacco flavors: menthol/mint, fruit, candy, or ‘other’ (e.g. Coffee).

Results: Vapers use a wide range of flavors, with 63.1% using a non-tobacco flavor. The most common flavor categories were fruit (29.4%) and tobacco (28.7%), followed by mint/menthol (14.4%) and candy (13.5%). Vapers using candy (41.0%, p<0.0001) or fruit flavors (26.0%, p=0.01) found vaping more satisfying (compared to smoking) than vapers using tobacco flavor (15.5%) and rated vaping as very/extremely enjoyable (fruit: 50.9%; candy: 60.9%) than those using tobacco flavor (39.4%). Among concurrent users, those using fruit (74.6%, p=0.04) or candy flavors (81.1%, p=0.003) were more likely than tobacco flavor users (63.5%) to vape in order to quit smoking. Flavor category was not associated with the likelihood of a quit attempt (p=0.46). Among exclusive vapers, tobacco and non-tobacco flavors were popular; however, those using tobacco (99.0%) were more likely than those using candy (72.8%, p=0.002) or unflavored (42.5%, p=0.005) to vape in order to stay quit.

Conclusions: A majority of regular vapers in Canada and the US use non-tobacco flavors. Greater satisfaction and enjoyment with vaping is higher among fruit and candy flavor users. While it does not appear that certain flavors are associated with a greater propensity to attempt to quit smoking among concurrent users, non-tobacco flavors are popular among former smokers who are exclusively vaping. Future research should determine the likely impact of flavor bans on those who are vaping to quit smoking or to stay quit.

Implications: Recent concerns about the attractiveness of e-cigarette flavors among youth have resulted in flavor restrictions in some jurisdictions of the United States and Canada. However, little is known about

the possible consequences for current and former smokers if they no longer have access to their preferred flavors. This study shows that a variety of nontobacco flavors, especially fruit, are popular among adult vapers, particularly among those who have quit smoking and are now exclusively vaping. Limiting access to flavors may therefore reduce the appeal of e-cigarettes among adults who are trying to quit smoking or stay quit.

Abstract

Introduction:

Limited research has investigated the relationship between multiple health conditions and subsequent quitting activities at the population level. This study examines whether nine health conditions and concerns related to smoking are predictive of quit attempts and success among those who tried.

Methods:

Data came from the International Tobacco Control Four Country Smoking and Vaping Survey conducted in Australia, Canada, England and the US. A total of 3998 daily smokers were surveyed in 2016 and recontacted in 2018. Respondents were asked in 2016 whether they had a medical diagnosis for depression, anxiety, alcohol problems, obesity, chronic pain, diabetes, heart disease, cancer, and chronic lung disease, and whether they had concerns about past/future health effects of smoking. Outcomes were quit attempts and success (having been abstinent for at least one month between surveys).

Results:

Across all four countries, 44.4% of smokers tried to quit between the two survey years, and of these 36.8% were successful. Concerns about past (adjusted odds ratio, AOR=1.66, 95% CI: 1.32–2.08, p<0.001) and future effects of smoking (AOR=2.17, 95% CI: 1.62–2.91, p<0.001) and most health conditions predicted quit attempts, but were mostly unrelated to quit success, with concerns about future effects (AOR=0.59, 95% CI: 0.35–0.99, p<0.05), chronic lung conditions (AOR=0.56, 95% CI: 0.37–0.86, p<0.01) and chronic pain (with a trend) being associated with lower success.

Conclusions:

Having a major chronic health condition does, generally, motivate making quit attempts, but in some cases it is associated with failure among those who try. More effective cessation support is required for these high priority groups.

Abstract

This descriptive study of smokers (smoked at least monthly) and recent ex-smokers (quit for ≤2 years) examined transitions over an 18 month period in their smoking and vaping behaviors. Data are from Waves 1 (W1: 2016) and 2 (W2: 2018) of the ITC Four Country Smoking and Vaping Survey, a cohort study of adult (≥18+) smokers, concurrent users (smoke and vape), and recent ex-smokers from Australia, Canada, England, and the United States (US). Respondents (N = 5016) were classified according to their smoking and vaping status, which resulted in eight subgroups: (1) exclusive daily smokers (2) exclusive non-daily smokers; (3–6) concurrent users (subdivided into four groups by each combination of daily/non-daily smoking and daily/non-daily vaping); (7) ex-smokers who vape; (8) ex-smokers not vaping. The analyses focused first on describing changes between groups from W1 to W2. Second, transition outcomes were assessed based on changes in smoking and vaping between W1 and W2. Transitions focused on smoking were: no change in smoking (continued smoking at the same frequency); decreased smoking; increased smoking; discontinued smoking; relapsed (ex-smokers at W1 who were smoking at W2). Transitions focused on vaping were: initiated vaping; switched from smoking to vaping. Overall, this study found that the vast majority of smokers were smoking 18 months later. Non-daily smokers were more likely than daily smokers to have discontinued smoking (p < 0.0001) and to have switched to exclusive vaping (p = 0.034). Exclusive non-daily smokers were more likely than exclusive daily smokers to have initiated vaping (p = 0.04). Among all W1 daily smokers, there were no differences in discontinued smoking between daily smokers who vaped (concurrent users) and exclusive daily smokers; however, concurrent users were more likely than exclusive daily smokers to have decreased to non-daily smoking (p < 0.001) or to have switched to vaping by W2 (p < 0.001). Among all W1 non-daily smokers, there were no significant differences in increased smoking or discontinued smoking between concurrent users or exclusive smokers. Most ex-smokers remained abstinent from smoking, and there was no difference in relapse back to smoking between those who vaped and those who did not.

Perceived relative harm of heated tobacco products (IQOS), e-cigarettes, and cigarettes among adults in Canada: Findings from the ITC Project. Tobacco Induced Diseases, 18(September), 81.

Abstract

Introduction:

Tobacco companies have introduced heated tobacco products (HTPs), such as IQOS, which may compete with e-cigarettes among smokers interested in switching to potentially reduced-risk products. Non-smokers may also start using IQOS if they believe this product is less harmful than other nicotine products. Smokers' and non-smokers' decisions may be driven by relative harm perceptions of emerging nicotine products. We aimed to examine relative harm perceptions between IQOS, e-cigarettes, and cigarettes, among nicotine product users and non-users.

Methods:

We conducted a web survey with Canadian respondents (aged >/ 20 years; n=268) in September-October 2018. Perceptions about relative harm between IQOS (available for sale since 2017 and subject to the same comprehensive marketing restrictions as cigarettes in Canada), e-cigarettes, and cigarettes, were assessed among nonusers (n=79), exclusive smokers (n=78), exclusive e-cigarette users (n=32), and dual users (n=79). Multiple logistic regression explored the association between relative harm perceptions and nicotine-use status, adjusting for sociodemographic variables.

Results:

Over half of respondents perceived IQOS as equally or more harmful than e-cigarettes (53.7%), while almost a quarter either reported IQOS as less harmful than e-cigarettes or were uncertain (22.7% and 23.5%, respectively). Two-thirds of respondents (65.7%) perceived e-cigarettes as less harmful than cigarettes, yet only half (48.1%) perceived IQOS as less harmful than cigarettes. Both exclusive and dual e-cigarette users, but not exclusive smokers, had higher odds of perceiving IQOS as more harmful than e-cigarettes and less harmful than cigarettes compared to non-users.

Conclusions:

Most nicotine users and non-users perceive differential health risk across IQOS, e-cigarettes, and cigarettes. Although e-cigarettes are generally viewed as less harmful than cigarettes, the perceived harm of IQOS was unclear.

European Journal of Public Health, 30(Suppl 3), iii91-iii97.

Abstract

Introduction: The European (EU) Tobacco Product Directive (TPD) was implemented in May 2016 to regulate the design and labelling of cigarettes and roll-your-own tobacco. At the same time, the UK introduced standardized packaging measures, whereas Germany, Greece, Hungary, Poland, Romania and Spain did not. This study examines the impact of introducing standardized packaging in England using a quasi-experimental design.

Material and Methods: Data from adult smokers in Waves 1 (2016; N=9547) and 2 (2018; N=9724) from the International Tobacco Control Policy Evaluation surveys (England) and EUREST-PLUS surveys (Germany, Greece, Hungary, Poland, Romania and Spain) were used. Generalized estimating equations were used to estimate changes in pack/brand appeal, salience of health-warning labels (HWLs) and perceived relative harm of different brands in England (where larger HWLs and standardized packaging were implemented), vs. each EU country (where only larger HWLs were implemented).

Results: There was an increase in the percentage of respondents from Germany, Hungary and Poland reporting they did not like the look of the pack (4.7%, 9.6%, and 14.2%, respectively), but the largest increase was in England (41.0%). Moreover, there was a statistically significant increase in the salience of HWLs in Hungary, Poland and Romania (17.0%, 13.9%, and 15.3%, respectively), but the largest increase was in England (27.6%). Few differences were observed in cross-country comparisons of the perceived relative harm of different brands.

Conclusions: Findings suggest that standardized packaging reduces pack appeal and enhances the salience of HWLs over and above the effects of larger HWLs. Findings provide additional evidence and support for incorporating standardized packaging into the EU TPD.

(2020). Quitting behaviours and cessation methods used in eight European Countries in 2018: Findings from the EUREST-PLUS ITC Europe Surveys. European Journal of Public Health, 30(Supplement_3), iii26-iii33

Abstract

Background:

We examined quit attempts, use of cessation assistance, quitting beliefs and intentions among smokers who participated in the 2018 International Tobacco Control (ITC) Europe Surveys in eight European Union Member States (England, Germany, Greece, Hungary, the Netherlands, Poland, Romania and Spain).

Methods:

Cross-sectional data from 11 543 smokers were collected from Wave 2 of the ITC Six European Country (6E) Survey (Germany, Greece, Hungary, Poland, Romania and Spain—2018), the ITC Netherlands Survey (the Netherlands—late 2017) and the Four Countries Smoking and Vaping (4CV1) Survey (England—2018). Logistic regression was used to examine associations between smokers’ characteristics and recent quit attempts.

Results:

Quit attempts in the past 12 months were more frequently reported by respondents in the Netherlands (33.0%) and England (29.3%) and least frequently in Hungary (11.5%), Greece (14.7%), Poland (16.7%) and Germany (16.7%). With the exception of England (35.9%), the majority (56–84%) of recent quit attempts was unaided. Making a quit attempt was associated with younger age, higher education and income, having a smoking-related illness and living in England. In all countries, the majority of continuing smokers did not intend to quit in the next 6 months, had moderate to high levels of nicotine dependence and perceived quitting to be difficult.

Conclusions:

Apart from England and the Netherlands, smokers made few quit attempts in the past year and had low intentions to quit in the near future. The use of cessation assistance was sub-optimal. There is a need to examine approaches to supporting quitting among the significant proportion of tobacco users in Europe and increase the use of cessation support as part of quit attempts

European Journal of Public Health, 30(Suppl 3), iii68-iii77.

Abstract

Background:

The 2016 European Tobacco Products Directive (TPD) required Member States (MS) to implement new regulations for electronic cigarettes (ECs). We conducted a longitudinal study to assess changes over 2 years in smokers’ support for EC policies and identify predictors of support in seven European countries after TPD implementation.

Methods:

Prospective cohort surveys were conducted among adult smokers in Germany, Greece, Hungary, Poland, Romania, Spain and England in 2016 (n = 9547; just after TPD) and 2018 (n = 10 287; 2 years after TPD). Multivariable logistic regression models employing generalized estimating equations assessed changes in support for four EC policies, and tested for country differences and strength of key predictors of support.

Results:

Banning EC use in smoke-free places was supported by 53.1% in 2016 and 54.6% in 2018 with a significant increase in Greece (51.7–66.0%) and a decrease in Spain (60.1–48.6%). Restricting EC/e-liquid nicotine content was supported by 52.2 and 47.4% in 2016 and 2018, respectively, with a significant decrease in England (54.2–46.5%) and Romania (52.5–41.0%). An EC promotion ban was supported by 41.1 and 40.2%. A flavour ban was supported by 33.3% and 32.3% with a significant increase in Hungary (34.3–43.3%). Support was generally higher in Poland, Hungary and Greece vs. England. Support was lower among dual and EC-only users, and low-income smokers.

Conclusions:

Smokers in all countries strongly supported banning EC use in smoke-free places and restricting nicotine content after TPD implementation, with no clear trends for changes in policy support.

European Journal of Public Health, 30(Suppl_3), iii26-iii33.

Abstract

Background:

This study presents perceptions of the harmfulness of electronic cigarettes (e-cigarettes) relative to combustible cigarettes among smokers from six European Union (EU) countries, prior to the implementation of the EU Tobacco Products Directive (TPD), and 2 years post-TPD.

Methods:

Data were drawn from the EUREST-PLUS ITC Europe Surveys, a cohort study of adult smokers (≥18 years) from Germany, Greece, Hungary, Poland, Romania and Spain. Data were collected in 2016 (pre-TPD: N = 6011) and 2018 (post-TPD: N = 6027). Weighted generalized estimating equations were used to estimate perceptions of the harmfulness of e-cigarettes compared to combustible cigarettes (less harmful, equally harmful, more harmful or 'don't know').

Results:

In 2016, among respondents who were aware of e-cigarettes (72.2%), 28.6% reported that they perceived e-cigarettes to be less harmful than cigarettes (range 22.0% in Spain to 34.1% in Hungary). In 2018, 72.2% of respondents were aware of e-cigarettes, of whom 28.4% reported perceiving that e-cigarettes are less harmful. The majority of respondents perceived e-cigarettes to be equally or more harmful than cigarettes in both 2016 (58.5%) and 2018 (61.8%, P > 0.05). Overall, there were no significant changes in the perceptions that e-cigarettes are less, equally or more harmful than cigarettes, but 'don't know' responses significantly decreased from 12.9% to 9.8% (P = 0.036). The only significant change within countries was a decrease in 'don't know' responses in Spain (19.3-9.4%, P = .001).

Conclusions:

The majority of respondents in these six EU countries perceived e-cigarettes to be equally or more harmful than combustible cigarettes.

(2020). Effectiveness of tobacco warning labels before and after implementation of the European Tobacco Products Directive: Findings from the longitudinal EUREST-PLUS ITC Europe Surveys. European Journal of Public Health, 30(Suppl 3), iii84-iii90

Abstract

Background:

Tobacco product packaging is a key part of marketing efforts to make tobacco use appealing. In contrast, large, prominent health warnings are intended to inform individuals about the risks of smoking. In the European Union, since May 2016, the Tobacco Products Directive 2014/40/EU (TPD2) requires tobacco product packages to carry combined health warnings consisting of a picture, a text warning and information on stop smoking services, covering 65% of the front and back of the packages.

Methods:

Key measures of warning label effectiveness (salience, cognitive reactions and behavioural reaction) before and after implementation of the TPD2, determinants of warning labels’ effectiveness and country differences were examined in a longitudinal sample of 6011 adult smokers from Germany, Greece, Hungary, Poland, Romania and Spain (EUREST-PLUS Project) using longitudinal Generalized Estimating Equations (GEE) models.

Results:

In the pooled sample, the warning labels’ effectiveness increased significantly over time in terms of salience (adjusted OR = 1.18; 95% CI: 1.03–1.35), while cognitive and behavioural reactions did not show clear increases. Generally, among women, more highly educated smokers and less addicted smokers, the effectiveness of warning labels tended to be higher.

Conclusion:

We found an increase in salience, but no clear increases for cognitive and behavioural reactions to the new warning labels as required by the TPD2. While it is likely that our study underestimated the impact of the new pictorial warning labels, it provides evidence that health messages on tobacco packaging are more salient when supported by large pictures.

European Journal of Public Health, 30(Suppl 3), iii98-iii107.

Abstract

Background:

The European Tobacco Products Directive (TPD), which went into effect in May 2016, regulates packaging design and labelling of cigarettes and roll-your-own (RYO) tobacco. The aim of the current study was to examine whether smokers and recent quitters in six European Union (EU) countries (Germany, Greece, Hungary, Poland, Romania and Spain) reported noticing TPD-related changes to packaging, and correlates of noticing these changes.

Methods:

Cross-sectional data from the Wave 2 of the ITC 6 European Country Survey in 2018 after implementation of the TPD. Bivariate analyses included adult smokers (n = 5597) and recent quitters (n = 412). Adjusted logistic regression analyses were restricted to the subset of current smokers (n = 5597) and conducted using SAS-callable SUDAAN.

Results:

Over half of smokers (58.2%) and 30% of quitters noticed at least one of five types of TPD related pack changes. Over one-quarter of all respondents noticed changes to health warnings (30.0%), standardized openings (27.7%), minimum pack unit size (27.9%), and the removal of tar, nicotine and carbon monoxide information (26.7%) on packaging. Cross-country differences were observed across all measures, with noticing all pack changes markedly lower in Spain than the other countries. Correlates of noticing specific pack changes included sociodemographic characteristics, smoking behaviours and related to packaging.

Conclusions:

This is one of the first cross-country studies to examine the extent to which TPD changes to cigarette and RYO tobacco packaging are being noticed by smokers and recent quitters. Findings indicate that the majority of smokers noticed at least one type of pack change, but this varied across countries and sub-populations.

(2020). Awareness and use of heated tobacco products among adult smokers in six European countries: Findings from the EUREST-PLUS ITC Europe Surveys. European Journal of Public Health, 30(Suppl 3), iii78-iii83.

Abstract

Background:

The study assessed awareness and use of heated tobacco products (HTPs) and factors that influenced these issues among cigarette smokers from six European countries in 2016 (Wave 1) and 2018 (Wave 2).

Methods:

A survey was conducted among a nationally representative sample of cigarette smokers aged 18 years or older from Germany, Greece, Hungary, Poland, Romania and Spain in 2016 (N = 6011) and 2018 (N = 6027; 53% of smokers from the previous wave were retained, regardless of smoking status and dropouts were replaced by a replenishment sample of smokers). Data were collected through face-to-face interviews. Estimates were produced using weighted data. The study presents the cross-sectional results.

Results:

Awareness of HTPs increased from 8% to 17% between the two waves. At Wave 1, 1.1% of the smokers declared having used HTPs at least once during their lifetime; and at Wave 2, this increased to 1.9% (around 1% or less in four countries, except for Greece and Romania where it was around 4%). Factors associated with HTPs use among those who had ever heard about these products at Wave 1 were country of residence, being a daily cigarette smoker and ever use of electronic cigarettes. At Wave 2, ever use of HTPs was significantly higher among those who had tried to quit smoking combustible cigarettes in the last 12 months, had tried electronic cigarettes during lifetime and perceived HTPs as less dangerous than combustible cigarettes; the country of residence was also associated with HTPs use.

Conclusion:

This study offers insights into the behaviours and perceptions of European adult smokers regarding HTPs, an important emerging issue in the field of tobacco control.

Social norms for ecigarettes and smoking: Associations with initiation of e-cigarette use, intentions to quit smoking and quit attempts: Findings from the EUREST-PLUS ITC Europe Surveys. European Journal of Public Health, 30(Suppl_3), iii46-iii54

Abstract

Background:

Social norms have received little attention in relation to electronic cigarettes (EC). The current study examine social norms for EC use and smoking tobacco, and their associations with (i) initiation of EC use, (ii) intention to quit smoking and (iii) attempts to quit smoking.

Methods:

Cross-sectional and longitudinal data analysis from Waves 1 and 2 of the ITC 6 European Country Survey and corresponding waves from England (the ITC Four Country Smoking and Vaping Survey). Current smokers at baseline, who heard of ECs and provided data at both waves were included (n = 3702). Complex samples logistic regression examined associations between the outcomes and descriptive (seeing EC use in public, close friends using ECs/smoking) and injunctive (public approves of ECs/smoking) norms, adjusting for country, demographics, EC use and heaviness of smoking.

Results:

In longitudinal analyses, seeing EC use in public at least some days was the only social norm that predicted initiation of EC use between waves (OR = 1.66, 95%CI = 1.08–2.56). In the cross-sectional analysis, having an intention to quit was associated with seeing EC use in public (OR = 1.37, 95%CI = 1.04–1.81) and reporting fewer than three close friends smoke (OR = 0.59, 95%CI = 0.44–0.80). There was no association between any social norm and making a quit attempt between waves.

Conclusions:

Initiation of EC use is predicted by seeing EC use in public, which was also associated with greater intention to quit smoking. Friends’ smoking was associated with lower intention to quit. These findings may allay concerns that increased visibility of ECs is renormalizing smoking amongst current smokers.

Changes in electronic cigarette use and label awareness among smokers before and after the European Tobacco Products Directive implementation in six European countries: Findings from the EUREST-PLUS ITC Europe Surveys. European Journal of Public Health, 30(Suppl_3), iii62-iii67.

Abstract

Background:

Article 20 of the European Tobacco Product Directive (TPD), which went into effect in May 2016, regulates electronic cigarettes (e-cigarettes) in the European Union (EU). The aim of this study was to evaluate changes in e-cigarette use, design attributes of the products used and awareness of e-cigarette labelling and packaging among smokers from six EU Member States (MS) before and after TPD implementation.

Methods:

Data come from Wave 1 (2016, pre-TPD) and Wave 2 (2018, post-TPD) of the ITC Six European Country Survey among a sample of smokers and recent quitters who use e-cigarettes from six EU MS. Weighted logistic generalized estimating equations regression models were estimated to test the change in binary outcomes between Waves 1 and 2 using SAS-callable SUDAAN.

Results:

In 2018, current daily/weekly e-cigarette use among adult smokers was just over 2%, but this varied from the highest in Greece (4%) to lowest in Poland (1.2%). From Waves 1 to 2, there was a significant increase in respondents reporting noticing and reading health and product safety information on leaflets inside e-cigarette packaging (8.39–11.62%, P < 0.001). There were no significant changes between waves of respondents reporting noticing or reading warning labels on e-cigarette packages/vials.

Conclusions:

E-cigarette use among smokers in these six EU countries is low. Although reported noticing and reading leaflets included in the packaging of e-cigarettes increased significantly from before to after the TPD, there was no significant change in reported noticing and reading of warning labels. Findings indicate the importance of continued monitoring of TPD provisions around e-cigarettes.

European Journal of Public Health, 30(Suppl_3), iii108- iii112.

Abstract

Background:

There is currently no comprehensive legislation protecting non-smokers and children from second-hand smoke (SHS) exposure in private cars at the European Union (EU) level. This study aims to assess smokers’ support for smoke-free cars legislation in six EU countries.

Methods:

Data come from the EUREST-PLUS ITC Europe Surveys: Wave 1 (2016, n = 6011) and Wave 2 (2018, n = 6027) conducted in Germany, Greece, Hungary, Poland, Romania and Spain. Support for smoke-free cars carrying pre-school children and non-smokers and voluntary implementation of smoke-free cars were assessed among adult smokers. Generalized estimating equations models were used to assess changes in support between waves.

Results:

In 2018, 96.3% [95% confidence interval (CI) 95.4–97.0%] of the overall sample supported smoke-free legislation for cars carrying pre-school children, representing an increase of 2.4 percentage points in comparison to 2016. Smoke-free legislation for cars transporting non-smokers was supported by 85.2% (95% CI 83.1–87.1%) of smokers’ in 2016 and 90.2% (95% CI 88.6–91.7%) in 2018. Among smokers who owned cars, there was a significant 7.2 percentage points increase in voluntary implementation of smoke-free cars carrying children from 2016 (60.7%, 95% CI 57.2–64.0%) to 2018 (67.9%, 95% CI 65.1–70.5%). All sociodemographic groups of smokers reported support higher than 80% in 2018.

Conclusion:

The vast majority of smokers in all six EU countries support smoke-free legislation for cars carrying pre-school children and non-smokers. This almost universal support across countries and sociodemographic groups is a clear indicator of a window of opportunity for the introduction of comprehensive legislation to protect non-smokers and children from SHS exposure in cars.

(2020). Transitions in product use during the implementation of the European Tobacco Products Directive: Cohort study findings from the EUREST-PLUS ITC Europe Surveys. European Journal of Public Health, 30(Suppl_3), iii10-iii17.

Abstract

Background:

The emergence of new types of tobacco and tobacco-related products on the European Union (EU) market has precipitated the possibility for both poly-tobacco use and transitions between products. In the EU, the regulatory environment has shifted with the implementation of the European Tobacco Products Directive (TPD) in May 2016, which may influence consumer transitions between products.

Methods:

The aim of this paper was to examine trends and transitions in tobacco products from 2016 to 2018 -before and after implementation of the TPD in the EU. Data come from Wave 1 (preTPD) and Wave 2 (post-TPD) of the EUREST-PLUS ITC Six European Country Survey, a cohort study of adults who at the time of recruitment were smokers from six EU countries- Germany, Greece, Hungary, Poland, Romania, and Spain. D (N = 3195). Bivariate and logistic regression analyses of weighted data was conducted using SAS-callable SUDAAN

Results:

Overall, among those who smoked factorymade cigarettes (FM) only at Wave 1, 4.3% switched to roll-your-own tobacco (RYO) only. Among RYO only users at Wave 1, 17.0% switched to FM only, however compared to all other countries, respondents from Hungary had the highest percentage of FM only users at Wave 1 switch to RYO only at Wave 2 (18.0%).

Conclusions:

The most prominent transition overall was from smoking RYO exclusively at Wave 1 to smoking FM tobacco exclusively at Wave 2, however this varied across countries. As the tobacco control regulatory environment of the EU develops, it is important to continue to monitor transitions between types of products, as well as trends in cessation.

European Journal of Public Health, 30(Supplement_3), iii34-iii37.

Abstract

The European Tobacco Products Directive (TPD) introduced a ban on characterizing flavours in cigarettes (2016), including menthol (2020). The longitudinal data analysis of the EUREST-PLUS International Tobacco Control (ITC) Project Europe Surveys (n = 16 534; Wave 1 in 2016 and Wave 2 in 2018) found significant but small declines in the weighted prevalence of menthol (by 0.94%; P = 0.041) and other flavoured cigarette use (by 1.32%; P < 0.001) following the 2016 TPD. The declines tended to be driven primarily by the menthol and flavoured cigarette (MFC) smokers switching to unflavoured tobacco. Cigarette consumption declined between waves, but there were no statistically significant difference in decline between MFC and unflavoured tobacco smokers on smoking and cessation behaviours between the waves.
