RESUMO
BACKGROUND: Social media use is high among children and young people and might influence health behaviours. We examined social media use and use of tobacco and e-cigarettes in the UK. METHODS: We used data from participants aged 10-25 years from the UK Household Longitudinal Study (January 2015-January 2022). Participants were asked: "On a normal weekday, that is Monday to Friday, how many hours do you spend chatting or interacting with friends through a social website or app like that?". Specific social media platforms were not specified. Responses were none, less than 1 h, 1-3 h, 4-6 h, 7 h or more. Outcomes were current tobacco smoking and e-cigarette use. Generalised Estimating Equation (GEE) logistic regression models investigated associations of social media use with tobacco and e-cigarette use, and fixed effects analyses investigated changes in social media use with uptake of both products. Models included possible confounders such as age, sex, household income, ethnicity (White vs non-White) and use of tobacco or e-cigarettes by others within the home. All participants gave written informed consent. FINDINGS: The analytic sample included 10â808 participants with 27â962 observations (mean age 15·7 years [SD 3·8], 5080 [47%] male, 5728 [53%] female, and 7868 [73%] White). Current tobacco smoking was reported at one or more timepoints by 929 (8·6%) participants, and current e-cigarette use by 270 (2·5%) participants. In adjusted GEE models, all levels of social media use were associated with greater odds of current smoking than no use. This association was particularly apparent at higher levels of use adjusted odds ratio [aOR] 3·11, 95% CIâ2·41-4·03 for ≥7 h use vs no use), with similar associations for e-cigarettes (aOR 3·04, 2·11-4·40 for ≥7 h use vs no use). Fixed effects analyses also found increased use of social media to be associated with increased uptake of both products (eg, changing to using social media for ≥7 h/day was associated with >2 times the odds of taking up tobacco smoking [aOR 2·33, 1·28-4·24]). INTERPRETATION: These analyses suggest an association between social media use and e-cigarette and tobacco use. Potential pathways include promotion of these products on social media. Further research with details on specific platforms would be useful as well as with longer follow-up time. FUNDING: Cancer Research UK.

INTRODUCTION: This study examined menthol cigarette use among youth who smoked, after menthol cigarette bans were implemented in England (May 2020) and Canada (October 2017). AIMS AND METHODS: Cross-sectional data come from 2021 ITC Youth Tobacco and Vaping Survey respondents aged 16-19 who smoked in the past 30 d in England (N = 715) and Canada (N = 419). Adjusted logistic regression models, estimated separately for each country, examined sociodemographic correlates of usually smoking menthol cigarettes (reporting currently most often smoking menthol cigarettes) overall, and by past 30-d use of any menthol accessories (e.g., filters, capsules). Youth reported the cigarette variety they smoked most often, coded as menthol or nonmenthol. RESULTS: Almost no youth who smoked in the past 30 d reported most often smoking a cigarette variety coded as menthol. However, 34.5% (95% CI: 30.4% to 38.9%) of youth who smoke in England and 30.9% (26.0%-36.3%) in Canada reported usually smoking menthol cigarettes, with greater odds of use among those identifying as black, or other race/ethnicity, respectively, compared to white in England (60.0%, aOR = 3.08, p = .001; 47.4%, aOR = 2.27, p = .011) and Canada (43.6%, aOR = 2.44, p = .046; 51.2%, aOR = 2.92, p = .001). Among those who reported usually smoking menthol cigarettes in England (N = 223) and Canada (N = 108), 71.7% (64.0%-78.2%) and 51.5% (41.1%-61.7%) reported using menthol accessories. CONCLUSIONS: After menthol cigarette bans in England and Canada, approximately one-third of youth who smoked reported usually smoking menthol cigarettes, with disproportionately higher use among those identifying as black and other race/ethnicity. Menthol accessories accounted for most menthol cigarette use. Closing regulatory loopholes is critical to advancing public health equity. IMPLICATIONS: Use of menthol cigarette accessories (eg, filters, cards, capsules) among youth who smoked was prevalent after implementation of menthol cigarette bans in England and Canada, and there was disproportionately higher use among those who identified as black and any other race/ethnicity. Efforts are therefore required to close regulatory loopholes of menthol cigarette bans. Findings further support countries, such as the United States, proposing menthol cigarette bans which extend coverage to accessories. More comprehensive menthol bans that also restrict accessories are likely to be more effective in reducing flavored tobacco use among young people and in advancing health equity.

BACKGROUND: Limited data on electronic cigarette prevalence, patterns, and settings of use are available from several European countries. METHODS: Within the TackSHS project, a face-to-face survey was conducted in 2017-2018 in 12 European countries (Bulgaria, England, France, Germany, Greece, Ireland, Italy, Latvia, Poland, Portugal, Romania and Spain). Overall, 11,876 participants, representative of the population aged ⩾15 years in each country, provided information on electronic cigarette. RESULTS: 2.4% (95% confidence interval [CI], 2.2-2.7%) of the subjects (2.5% among men and 2.4% among women; 0.4% among never, 4.4% among current- and 6.5% among ex-smokers) reported current use of electronic cigarette, ranging from 0.6% in Spain to 7.2% in England. Of the 272 electronic cigarette users, 52.6% were dual users (ie, users of both electronic and conventional cigarettes) and 58.8% used liquids with nicotine. In all, 65.1% reported using electronic cigarette in at least one indoor setting where smoking is forbidden; in particular, at workplaces (34.9%) and bars and restaurants (41.5%). Multivariable logistic regression analysis showed that electronic cigarette use was lower among older individuals (P for trend <0.001) and higher among individuals with high level of education (P for trend = 0.040). Participants from countries with higher tobacco cigarette prices more frequently reported electronic cigarette use (odds ratio 3.62; 95% CI, 1.80-7.30). CONCLUSION: Considering the whole adult population of these 12 European countries, more than 8.3 million people use electronic cigarettes. The majority of users also smoked conventional cigarettes, used electronic cigarettes with nicotine, and consumed electronic cigarettes in smoke-free indoor areas.

BACKGROUND: Global adoption of standardised packaging requirements for tobacco products is a victory for public health, but their proliferation and impacts rely partly on public support. How this is related to legislation remains underassessed. This study explored change over time in public support for standardised packaging in countries with varying degrees of legislative provisions. METHODS: We used data from 27 European countries, collected from 2017 (n=28, 300) and 2020 (n=27, 901) waves of the Eurobarometer survey, to assess self-reported support for standardised packaging regulations among both smokers and non-smokers. Countries were grouped into three categories of policy adoption (policy implemented; policy legislated; no legislation) and changes in support were assessed using multilevel Poisson regression models. RESULTS: In 2020, public support for standardised packaging was 71% (95% CI 68% to 74%) in countries that implemented standardised packaging legislation, 57% (55% to 60%) in countries that had legislated but not yet implemented legislation and 41% (40%to 42%) in countries with no legislation. Compared with 2017, this represented a relative change of +8% (1% to 15%), +12% (5% to 21%) and -5% (95% CI -2% to -8%), respectively, in the three country categories. Among smokers, there was no indication of change in support across the three groups. Among non-smokers, support increased in countries with existing legislation (adjusted prevalence ratio [aPR]=1.14, 95% CI 1.06 to 1.23) and decreased in countries with no legislation (aPR=0.93, 0.90 to 0.97). CONCLUSIONS: Public support for standardised packaging regulations increased in countries implementing and legislating for these measures, particularly among non-smokers. An overall increase in support provides reassurance for policymakers defending policy action on tobacco packaging, as well as for those seeking to implement standardised packaging in their own countries. .

OBJECTIVE: This systematic review aims to identify marketing elements of flavour capsule variants (FCVs), cigarettes that release flavour when a capsule(s) embedded in the filter is crushed. DATA SOURCES: A search of original research without restrictions in publication year, population, study design or language using a combination of cigarette and capsule terms was conducted across four databases (Medline, Embase, Web of Science and Scopus), indexed until 13 December 2021, along with a citation search. STUDY SELECTION: Studies were included if they presented original research relevant to marketing features of FCVs. DATA EXTRACTION: One author performed data extraction and coded outcomes based on '4Ps' of marketing mix theory: product, place, price and promotion. The second author conducted a cross-check. DATA SYNTHESIS: Of 2436 unduplicated database records and 30 records from other sources, 40 studies were included in the review. Studies were published between 2009 and 2021. Study methodologies primarily included content analysis of cigarette packs/sticks, review of tobacco industry documents and content analysis of advertising information. Findings suggest FCVs are marketed using a mix of strategies, particularly characterised by product innovation, timing market launches around tobacco policies, point-of-sale advertising and packaging to communicate a high-tech, customisable and flavourful product. CONCLUSION: Findings illuminate the marketing strategies of FCVs that are likely driving their global growth, particularly among young people and in low and middle-income countries. Comprehensive tobacco control regulations are needed to close loopholes and curb industry efforts to circumvent existing policies in order to mitigate uptake of FCVs and other product innovations.

OBJECTIVE: This systematic review on flavour capsule cigarettes aims to examine prevalence, correlates of use, behaviours and perceptions of these products globally. DATA SOURCES: A search of original, peer-reviewed research without restrictions in publication year, population, study design or language, using a combination of cigarette and capsule terms was conducted across four databases (Medline, Embase, Web of Science and Scopus), indexed until 30 April 2021. STUDY SELECTION: Studies were included if they presented original, human subjects research on flavour capsule cigarettes. DATA EXTRACTION: Two authors independently extracted data on main outcome results and assessed risk of bias using a validated quality assessment tool (QATSDD). DATA SYNTHESIS: Of 842 unduplicated database records and four studies from citation searching screened, 20 studies were included in the review. Studies reported data from 2009 to 2019 across eight countries, the majority of which used cross-sectional or focus group study designs. Current capsule use among smokers was highest in Chile and Mexico (40%) and was associated with younger age, and in some countries, with being female. Capsule cigarettes are perceived as tasting better, being smoother on the throat, more fun to smoke, and more attractive compared with non-capsule cigarettes, particularly among susceptible non-smokers and non-daily smokers. CONCLUSION: Findings call for the adoption of comprehensive tobacco control policies that account for flavour capsules and similar iterations, which can increase appeal through flavours and innovative features. Continued monitoring and research of these products is critical, with particular attention to low-income and middle-income countries, which make up a disproportionately larger share of the capsule market.

INTRODUCTION: E-cigarette use remains a controversial topic, with questions over how people transition between e-cigarette use and cigarette smoking. This paper examined transitions into and out of nicotine product use in a representative sample of UK youth. METHODS: We used Markov multistate transition probability models on data from 10 229 participants (10-25 years old) in the UK Household Longitudinal Study (2015-2021). We used four product use states ('never', 'non-current use', 'e-cigarette only' and 'smoking and dual use') and estimated likelihood of transitions according to sociodemographic characteristics. RESULTS: Among participants who had never used nicotine products, most were still non-users a year later (92.9% probability; 95% CI 92.6%, 93.2%); a small proportion transitioned to using e-cigarettes only (4.0%; 95% CI 3.7%, 4.2%) and cigarettes (2.2%; 95% CI 2.0%, 2.4%). Those aged 14-17 years were the most likely to start using a nicotine product. E-cigarette use was less persistent overtime than cigarette smoking, with a 59.1% probability (95% CI 56.9%, 61.0%) of e-cigarette users still using after 1 year compared with 73.8% (95% CI 72.1%, 75.4%) for cigarette smoking. However, there was a 14% probability (95% CI 12.8%, 16.2%) that e-cigarette users went onto smoke cigarettes after 1 year, rising to 25% (95% CI 23%, 27%) after 3 years. CONCLUSION: This study found that although overall nicotine product use was relatively rare, participants were more likely to experiment with e-cigarette use than cigarette smoking. This was mostly not persistent over time; however, approximately one in seven transitioned to cigarette smoking. Regulators should aim to deter all nicotine product use among children.
RESUMO
INTRODUCTION: Raising tobacco prices via increased taxation may be undermined by tobacco industry tactics to keep budget cigarettes on the market. Price differentials between budget and premium cigarettes allow smokers to trade down in the face of average price rises thus attenuating health benefits. This study examines global trends of price differentials and associations with taxation. METHODS: Ecological analysis of country-level panel data of 195 countries' price differentials was performed and compared against total, specific excise, ad valorem and other taxation. Price differentials were expressed as the difference between budget cigarette and premium pack prices (as % of premium pack prices). Two-level linear regression models with repeated measurements (2014, 2016 and 2018) nested within each country assessed the association between country-level taxation structures and price differentials, adjusted for year, geographical region and income group. RESULTS: Worldwide, median price differential between budget and premium 20-cigarette packs was 49.4% (IQR 25.9%-70.0%) in 2014 and 44.4% (IQR 22.5%-69.4%) in 2018 with significant regional variation. The largest price differentials in 2018 were in Africa, with the lowest in Europe. Total taxation was negatively associated with price differentials (-1.5%, 95% CI -2.5% to -0.4% per +10% total taxation) as was specific excise taxation (-2.5%, 95% CI -3.7% to -1.2% per +10% specific excise tax). We found no statistically significant association between ad valorem taxation and price differentials. CONCLUSION: Total levels of taxation and specific excise taxes were associated with smaller price differentials. Implementing high specific excise taxes may reduce price differentials and improve health outcomes.

INTRODUCTION: It is illegal in the UK to sell tobacco or nicotine e-cigarettes to people under the age of 18 years, as is displaying tobacco cigarettes at the point of sale. This paper examined changes in exposure to display of these products in shops and sources of these products among children and adolescent users over time METHODS: Data from representative repeated online cross-sectional surveys of youth in Great Britain (11-18 years) were used (2018-2022; n=12 445). Outcome measures included noticing product displays and sources of e-cigarettes and tobacco cigarettes. Logistic regressions examined the associations of these outcome variables over time and with sociodemographic variables. RESULTS: Of 12 040 participants with complete data, 10.1% used some form of nicotine product (4.2% cigarettes, 2.9% e-cigarettes, 3.0% both) at least occasionally. The likelihood of noticing tobacco cigarettes on display fell over time for both supermarkets (2018: 67.1% to 2022: 58.5%) and small shops (2018: 81.3% to 2022: 66.3%), but the likelihood of noticing e-cigarettes in supermarkets rose (2018: 57.4% to 2022: 66.5%). Sources of tobacco cigarettes did not differ over time, but e-cigarette users were more likely to get their e-cigarettes from small shops in 2022 (51.2%) vs 2019 (34.2%) (OR 2.02, 95% CI 1.24, 3.29). CONCLUSION: This study provides evidence that current policies to limit awareness of and access to both tobacco and e-cigarettes among adolescents in the UK may not be effective. UK policies on the advertising, promotion and sale of both tobacco and e-cigarettes need to be reinforced to deter use among children and adolescents.
RESUMO
BACKGROUND: Patterning of cigarette and e-cigarette use among young people remains poorly characterized. We aimed to describe these patterns in the UK Millennium Cohort Study at age 14 and 17 years. METHODS: Data on cigarette and e-cigarette use come from 9731 adolescents. Latent class analysis assigned participants to membership of classes of product use and multinomial logistic regression analyses assessed differences in the likelihood of belonging to classes by sociodemographic (age, gender, ethnicity, household income, maternal education and country of residence) and smoking-related social factors (caregiver tobacco use, caregiver e-cigarette use and peer smoking). RESULTS: We identified four classes of use: 45.8% of adolescents 'continued to abstain' from cigarettes or e-cigarettes; 21.3% 'experimented' (used once or in the past but not currently) with cigarettes and/or e-cigarettes by age 17 but were not current users; 19.0% were 'late adopters', characterized by low levels of use at age 14 but high levels of experimentation and current use at age 17; and 13.9% were 'early adopters', characterized by high levels of experimentation and current use at ages 14 and 17. At age 17, 70.4% of 'early adopters' smoked cigarettes regularly plus an additional 27.3% experimented with cigarettes. Corresponding percentages for e-cigarettes were 37.9% and 58.9%. Tobacco and e-cigarette use by caregivers, and cigarette use by peers, were associated with being both 'late adopters' and 'early adopters'. CONCLUSIONS: Approximately one in seven adolescents in the UK are 'early adopters' of nicotine products. This highlights the need to develop and implement effective policies to prevent nicotine use uptake.
RESUMO
BACKGROUND: The 2020 European Union (EU) menthol cigarette ban increased quitting among pre-ban menthol smokers in the Netherlands, but some reported continuing to smoke menthol cigarettes. This study examined three possible explanations for post-ban menthol use-(i) illicit purchasing, (ii) use of flavour accessories and (iii) use of non-menthol replacement brands marketed for menthol smokers. METHODS: Data were from the ITC Netherlands Cohort Surveys among adult smokers before the menthol ban (Wave 1: February-March 2020, N = 2067) and after the ban (Wave 2: September-November 2020, N = 1752; Wave 3: June-July 2021, N = 1721). Bivariate, logistic regression and generalized estimating equation model analyses were conducted on weighted data. RESULTS: Illicit purchasing remained low from pre-ban (2.4%, 95% CI: 1.8-3.2, Wave 1) to post-ban (1.7%, 1.2-2.5%, Wave 3), with no difference between menthol and non-menthol smokers from Wave 1 to Wave 3. About 4.4% of post-ban menthol smokers last purchased their usual brand outside of the EU and 3.6% from the internet; 42.5% of post-ban menthol smokers and 4.4% of smokers overall reported using flavour accessories, with greater odds among those aged 25-39 years vs. 55+ (aOR = 3.16, P = 0.002). Approximately 70% of post-ban smokers who reported using a menthol brand were actually using a non-menthol replacement brand. CONCLUSIONS: There was no increase in illicit purchasing or of smuggling outside the EU among menthol and non-menthol smokers in the Netherlands 1 year after the EU menthol cigarette ban. Use of flavour accessories and non-menthol replacement brands best explain post-ban menthol use, suggesting the need to ban accessories and ensure industry compliance.

Vaccination has saved millions of lives. Vaccine hesitancy was recently declared a major threat to health by the World Health Organisation. Sociodemographic variables and knowledge level about vaccines have been suggested previously to affect vaccine uptake. This study aimed to investigate how levels of vaccination knowledge and concerns around safety of vaccines varied across sociodemographic factors in the European Union and United Kingdom. Levels and sources of knowledge and vaccine attitude patterns were examined across different areas of Europe. Data from the March 2019 Eurobarometer survey was used in this study which had 27,524 participants across the European Union and the United Kingdom. Two-level logistic and linear regressions were used to look for associations between sociodemographic variables, vaccine attitudes and knowledge level. Those who trusted information from healthcare workers and healthcare authorities were most likely to have positive vaccine attitudes; those trusting internet sources the most were the least likely. Those with greater vaccine related knowledge were more likely to report positive vaccination attitudes. Healthcare workers are key to dissemination of vaccination advice however many are becoming hesitant themselves. An increasing number of people are seeking online sources for vaccination information, and this has implications with information accuracy and vaccine hesitancy. A considerable proportion of the adult population in the European Union and the United Kingdom was concerned about the safety or side effects of vaccines. Continued efforts to increase trust in vaccines both in whole populations and specific groups are needed.

Brazil became the first country to approve a national policy to ban all flavour additives in all tobacco leaf products in 2012. However, as of February 2022, the policy remained to be implemented. Cross-sectional data come from the International Tobacco Control (ITC) Brazil Wave 3 Survey among adult smokers (N = 1216) in 2016-2017. The majority of smokers supported a ban on menthol (56.0%; 95%CI: 51.7-60.2%) and a ban on all additives (61.7%; 57.5-65.8%), with no significant differences across sociodemographic groups in adjusted logistic regression models. More than half of menthol smokers reported they would either quit or reduce the amount they smoked if menthol cigarettes were banned. Findings suggest that there is support for Brazil's ban on flavour additives, which is a determinant of successful policy implemented. Continued delays will postpone an important measure with demonstrated public health gains.

BACKGROUND: Ischemic strokes in orally anticoagulated patients pose challenges for acute management and secondary prevention but the characteristics of these strokes are poorly understood. We examined the clinical and imaging features, the presumed underlying etiology and the subsequent antithrombotic management. METHODS: We analyzed a consecutive series of patients enrolled into the EIDASAF study, a single center, observational study of ischemic stroke patients with a diagnosis atrial fibrillation (AF) prior to the index event who had been admitted to the Hyperacute Stroke Unit of Imperial College London between 2010 and 2017. We compared patients with oral anticoagulation therapy prior admission (OACprior ) with those without anticoagulation (OACnaive ). Brain imaging was analyzed centrally. RESULTS: 763 patients were included in the analysis. 481 (63%) were OACnaive while 282 (37%) were OACprior . Patients with OACprior were younger, more often had a previous history of stroke or transient ischemic attack (TIA), and more often suffered from hypertension and diabetes. In OACnaive, patients, large and deep middle cerebral artery infarcts occurred more often than in OACprior patients. The groups differed significantly in the distribution of competing etiologies underlying their stroke. At discharge, OACprior more frequently were (re)-anticoagulated compared to OACnaive patients. Within the OACprior group, patients with recurrent strokes did not differ from those with a first stroke regarding clinical characteristics and pattern of cerebral infarction but they were less frequently anticoagulated. CONCLUSIONS: Ischemic strokes on OAC represent a significant proportion of AF-related strokes. There is an unmet need to better understand the causes underlying these strokes and to optimize the medical management.

BACKGROUND: Recent years have seen a rapid increase in the popularity of electronic cigarettes (e-cigarettes) among adolescents in the USA. Evidence on their role in the continuation of or abstinence from cigarette smoking among young smokers remains scarce. OBJECTIVE: To examine the relationship between e-cigarette use initiated after cigarette smoking and abstinence from cigarette smoking among US adolescent established smokers. METHODS: The data were drawn from the 2015-2018 National Youth Tobacco Survey-a nationally representative survey of US middle and high school students. Multivariable logistic regression was used to assess the association between ever e-cigarette use and past 30-day abstinence from cigarette smoking. The analytical sample comprised ever established cigarette smokers with or without a history of e-cigarette use after smoking initiation. RESULTS: Neither experimental (adjusted OR 0.67, 95% CI 0.39-1.14) nor prior established (adjusted OR 1.56, 95% CI 0.96-2.56) nor current established (adjusted OR 0.65, 95% CI 0.41-1.03) e-cigarette use was statistically significantly associated with subsequent abstinence from cigarette smoking among adolescent ever established smokers. These findings were largely consistent across sensitivity analyses using alternative key definitions, although experimental and current established e-cigarette use was significantly negatively associated with past 6-month abstinence. CONCLUSIONS: We found no evidence that e-cigarette use among US adolescents already smoking cigarettes is associated with subsequent abstinence from cigarette smoking; there was some evidence of an inverse association among experimental and current established e-cigarette users. These findings could inform future regulatory and public health efforts regarding youth e-cigarette use and the reduction of youth cigarette smoking in the USA.

INTRODUCTION: To reduce the appeal of tobacco, the European Union (EU) banned menthol as a characterising flavour in cigarettes in May 2020. This pre/post-study evaluated the impact of the menthol ban on smoking cessation outcomes among a representative cohort of Dutch smokers. METHODS: Adult (18+ years) smokers were recruited at wave 1 (pre-ban) of the International Tobacco Control Netherlands Surveys (February-March 2020) and followed post-ban at wave 2 (September-November 2020) and wave 3 (June-July 2021) (N=1326 participated in all three waves). Weighted bivariate, logistic regression and generalised estimating equation model analyses were conducted. RESULTS: Usual menthol use decreased from pre-ban (7.8%) to post-ban (4.0% at wave 2 and 4.4% at wave 3) (p<0.001). Pre-ban menthol smokers had greater odds of making a post-ban quit attempt than non-menthol smokers (66.9% vs 49.6%, adjusted OR (aOR)=1.89, 95% CI: 1.13 to 3.16). Compared with pre-ban non-menthol smokers, a higher proportion of menthol smokers quit by wave 2 (17.8% vs 10.2%, p=0.025) and by wave 3 (26.1% vs 14.1%, p=0.002), although this was not significant after adjusting for other factors. Female pre-ban menthol smokers had greater odds of quitting by wave 3 than female non-menthol smokers (aOR=2.23, 95% CI: 1.10 to 4.51). Most pre-ban menthol smokers (n=99) switched to non-menthol cigarettes (40.0%) or reported that they continued to smoke menthol cigarettes (33.0%) at wave 3. CONCLUSIONS: The EU menthol ban was effective in reducing menthol use and in increasing quit attempts and quitting among pre-ban menthol smokers. Impact could be maximised by closing gaps that allow post-ban menthol cigarette use.
RESUMO
Standardised packaging of tobacco products is intended to reduce the appeal of smoking, but the tobacco industry claims this increases illicit trade. We examined the percentage of people reporting being offered illicit cigarettes before and after full implementation of standardised packaging in the UK, Ireland and France and compared this to other European Union countries. Reported ever illicit cigarette exposure fell from 19.8% to 18.1% between 2015 and 2018 in the three countries fully implementing the policy, and from 19.6% to 17.0% in control countries (p for difference=0.320). Standardised packaging does not appear to increase the availability of illicit cigarettes.

Despite their implications for tobacco control, data on concurrent dual (using two tobacco products) and poly-tobacco use (using more than two products) are relatively scarce globally. This study aimed to estimate the prevalence of dual and poly-tobacco use among men in 19 low-and middle-income countries (LMICs) and assess potential associations with individual and country level factors. Data from 19 LMICs were obtained from the most recent wave of the Demographic and Health Survey (DHS), collected between 2015 and 2016 comprising 235,975 men aged 15-49 years. The prevalence of current single, dual and poly-tobacco use were estimated using available sample weights. Mixed-effect multilevel models were used to estimate associations of individual and country level factors with tobacco use. Results showed that the prevalence of dual or poly-tobacco use among men was highest in Timor Leste (27.1%), Nepal (18.3%), Lesotho (13.2%) and India (9.3%). Factors associated with dual and poly-tobacco use were older age, low academic achievement, low income status, being divorced, living in urban areas and high frequency of media use. Among country-level characteristics, national wealth was not associated with dual and poly-tobacco use. Implementation of MPOWER measures was inversely associated with single tobacco use; this was not the case for dual and poly-tobacco use. Findings suggest that dual and poly-tobacco use are common among men especially in South-East Asian countries. This study highlights the need for MPOWER measures to be expanded and strengthened to address all tobacco products and explicitly consider dual and poly use.

INTRODUCTION: Improving understanding of the epidemiology of dual and poly-tobacco product use is essential for tobacco control policy and practice. The present study aimed to systematically review existing epidemiologic evidence on current dual and poly-tobacco use among adults globally. METHODS: We systematically searched online databases for studies published up to June 30, 2020. We included quantitative studies with measures of nationally representative prevalence of current dual or poly-tobacco use among adults. Prevalence estimates for each country were extracted manually and stratified by WHO regions and World Bank income classifications. RESULTS: Twenty studies with nationally representative prevalence data on current dual or poly-tobacco use in the adult population across 48 countries were included. Definitions of dual and poly-tobacco use varied widely. Prevalence of dual and poly-tobacco use was higher in low- and lower-middle-income countries compared to other higher-income countries. Current dual use of smoked and smokeless tobacco products among males ranged from 0.2% in Ukraine (2010) and Mexico (2009) to 17.9% in Nepal (2011). Poly-tobacco use among males ranged from 0.8% in Mexico (2009) and 0.9% in Argentina (2010) to 11.4% in the United Kingdom and 11.9% in Denmark in 2012. Dual tobacco use was generally higher in South-East Asia; poly-tobacco use was prevalent in Europe as well as in South-East Asia. CONCLUSIONS: This is the first systematic review of the prevalence estimates of dual and poly-tobacco use among adults globally. The results of the current study could significantly help health policy makers to implement effective tobacco control policies. IMPLICATIONS: This study demonstrates that dual/poly-tobacco use is common in many countries of the world, and highlights the need for in-depth exploration of this field in future studies, especially in high prevalence regions such as South-East Asian and European countries. In light of this, the global tobacco control community and health authorities should also agree upon a consistent operational definition of dual and poly-tobacco use to propel research and improve surveillance of dual/poly-use in health surveys for better communication and understanding of these phenomena.

BACKGROUND: Population data on tobacco use and its determinants require continuous monitoring and careful inter-country comparison. We aimed to provide the most up-to-date estimates on tobacco smoking from a large cross-sectional survey, conducted in selected European countries. METHODS: Within the TackSHS Project, a face-to-face survey on smoking was conducted in 2017-2018 in 12 countries: Bulgaria, England, France, Germany, Greece, Ireland, Italy, Latvia, Poland, Portugal, Romania, and Spain, representing around 80% of the 432 million European Union (EU) adult population. In each country, a representative sample of around 1,000 subjects aged 15 years and older was interviewed, for a total of 11,902 participants. RESULTS: Overall, 25.9% of participants were current smokers (31.0% of men and 21.2% of women, P < 0.001), while 16.5% were former smokers. Smoking prevalence ranged from 18.9% in Italy to 37.0% in Bulgaria. It decreased with increasing age (compared to <45, multivariable odds ratio [OR] for ≥65 year, 0.31; 95% confidence interval [CI], 0.27-0.36), level of education (OR for low vs high, 1.32; 95% CI, 1.17-1.48) and self-rated household economic level (OR for low vs high, 2.05; 95% CI, 1.74-2.42). The same patterns were found in both sexes. CONCLUSIONS: These smoking prevalence estimates represent the most up-to-date evidence in Europe. From them, it can be derived that there are more than 112 million current smokers in the EU-28. Lower socio-economic status is a major determinant of smoking habit in both sexes.
