Physician-brief advice for promoting smoking cessation among cancer patients on treatment in low and middle-income countries: a scoping review.

INTRODUCTION: Physician-brief advice has been utilized in high-income countries to promote smoking cessation among cancer patients. Empirical evidence on its effectiveness among cancer patients in low and middle-income countries (LMICs) is lacking. The gap could be due to inadequate training, and competing healthcare priorities, leading to insufficient implementation of targeted smoking cessation interventions in oncology settings. We undertook this scoping review to determine if physician-brief advice is effective in promoting smoking cessation among cancer patients in LMICs. METHODS: We conducted a literature search of all relevant articles across five databases: Cochrane Central Register of Controlled Trials, Cochrane Library (Tobacco Addiction Group trials), World Conference on Lung Cancer proceedings, PubMed, and Google Scholar up to November 2023, using pre-defined inclusion criteria and keywords. The study population was cancer survivors in LMICs, the intervention was smoking cessation advice by a physician in a clinic or oncology center during a consultation, and the outcome was the effect of smoking cessation programs in discontinuing smoking among cancer survivors in LMICs. RESULTS: Overall, out of every 10 cancer patients in LMICs, about seven were smokers, and one-half had received physician-brief advice for smoking cessation. Physician-brief advice was more likely to be delivered to patients with smoking-related cancer (Cohen's d = 0.396). This means that there is a noticeable difference between patients with smoking-related cancer compared to those with cancer unrelated to smoking. Smoking cessation failure was due to the inability to cope with the symptoms of withdrawal, missed smoking cessation clinic visits, mental health disorders, limited time and resources, and minimal patient-physician contact. CONCLUSION: There is very little literature on the frequency of use or the efficacy of physician-brief advice on smoking cessation in LMICs. The literature suggests that cancer patients in LMICs have low self-efficacy to quit smoking, and smoking cessation is rarely part of cancer care in LMICs. Physicians in LMICs should be trained to use motivational messages and good counseling techniques to improve smoking cessation among cancer patients. Policymakers should allocate the resources to implement physician-brief advice and design training programs for physicians focusing on physician-brief advice tailored to cancer patients.

Combining Inserts With Warning Labels on Cigarette Packs to Promote Smoking Cessation: A 2-Week Randomized Trial.

BACKGROUND: Cigarette pack inserts with messages on cessation benefits and advice are a promising labeling policy that may help promote smoking cessation. PURPOSE: To assess insert effects, with and without accompanying pictorial health warning labels(HWLs), on hypothesized psychosocial and behavioral outcomes. METHODS: We conducted a 2 × 2 between-subject randomized trial (inserts with efficacy messages vs. no inserts; large pictorial HWLs vs. small text HWLs), with 367 adults who smoked at least 10 cigarettes a day. Participants received a 14-day supply of their preferred cigarettes with packs modified to reflect their experimental condition. Over 2 weeks, we surveyed participants approximately 4-5 times a day during their smoking sessions, querying feelings about smoking, level of worry about harms from smoking, self-efficacy to cut down on cigarettes, self-efficacy to quit, hopefulness about quitting, and motivation to quit. Each evening, participants reported their perceived susceptibility to smoking harms and, for the last 24 hr, their frequency of thinking about smoking harms and cessation benefits, conversations about smoking cessation or harms, and foregoing or stubbing out cigarettes before they finished smoking. Mixed-effects ordinal and logistic models were estimated to evaluate differences between groups. RESULTS: Participants whose packs included inserts were more likely than those whose packs did not include inserts to report foregoing or stubbing out of cigarettes (OR = 2.39, 95% CI = 1.36, 4.20). Otherwise, no statistically significant associations were found between labeling conditions and outcomes. CONCLUSIONS: This study provides some evidence, albeit limited, that pack inserts with efficacy messages can promote behaviors that predict smoking cessation attempts.

Cigarette pack inserts (small leaflets inside packs) with messages about quitting benefits and tips to quit may promote smoking cessation. We randomly assigned 367 adult smokers to one of four groups: control group with small health warning labels (HWLs) on the side of packs; inserts with cessation messages and small HWLs; large picture HWLs showing health effects from smoking; inserts and large picture HWLs. Participants received a 14-day supply of their preferred cigarettes in packs that reflected their assigned group. Over 2 weeks, we surveyed participants 4­5 times a day during times when they smoked, asking their feelings about smoking and smoking-related harms, confidence to reduce cigarettes and quit, hopefulness about quitting, and motivation to quit. Each evening, participants reported on the prior 24 hr: how often they thought about smoking harms and cessation benefits; conversations about smoking cessation or harms; and foregoing or stubbing out cigarettes before they finished smoking. People whose packs had inserts (with or without picture HWLs) were more likely than those whose packs did not include inserts (control group or picture HWLs only) to report foregoing or stubbing out of cigarettes. This study provides some evidence that inserts with cessation messages may promote smoking cessation.

A Critical Review of E-Cigarette Regulation in China: Challenges and Prospects for Youth Prevention and Tobacco Control.

INTRODUCTION: The increasing popularity of electronic cigarettes (e-cigarettes) has led to the emergence of public health concerns, particularly among the youth. As a major producer and exporter of e-cigarettes, China has faced public health challenges in regulating the unregulated e-cigarette industry. AIMS AND METHODS: This study aims to evaluate the regulatory development of e-cigarettes in China. We searched and obtained national policy documents related to e-cigarettes and subnational smoke-free laws from LexisNexis on August 2, 2023, which were enacted between January 1, 2023 and July 31, 2023. We used 99 policy documents for the final analysis, specifically 68 national policy documents on e-cigarettes and 31 subnational smoke-free laws. We chronologically reviewed these policy documents in full text and summarized them on the basis of their content and the requirements of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC). RESULTS: Chinese policymakers established the current regulatory framework for e-cigarettes by amending, enacting, and enforcing laws and regulations. E-cigarettes are categorized as tobacco products, and the State Tobacco Monopoly Administration regulates the e-cigarette industry. The Chinese authorities prioritize youth prevention in strengthening the regulation on e-cigarettes. China adopts various tobacco control measures for e-cigarettes and cigarettes. CONCLUSIONS: China gained certain degrees of progress on tobacco control by regulating e-cigarettes and adopting measures required by the WHO FCTC. However, tobacco monopoly hinders the full realization of tobacco control goals, which necessitates the National Health Commission to assume its responsibility for the complete implementation of the WHO FCTC. IMPLICATIONS: This study presents a critical review of the development of e-cigarette regulation in China by reviewing relevant policy documents and analyzing tobacco control measures. It recognizes the degrees of progress of tobacco control measures and highlights tobacco monopoly as a significant hindrance of the full implementation of the WHO FCTC. Furthermore, empirical studies are required on the enforcement of tobacco control measures in China.

The Challenges of Tobacco Fiscal Policy Implementation in Mexico From the Perspective of Key Actors.

INTRODUCTION: Raising tobacco taxes is considered the most effective strategy to avoid smoking initiation and discourage its use, especially among vulnerable groups. However, few low- and middle-income countries have adopted high tobacco taxes. Raising taxes is, therefore, an opportunity to strengthen and accelerate tobacco control. The objective of this study is to analyze the barriers and facilitators to the tobacco tax increase in Mexico. AIMS AND METHODS: Based on the Governance Analytical Framework, data were generated through 17 in-depth interviews with key intersectoral actors for fiscal policy. The interviews were transcribed and coded according to Hufty's theory of governance. RESULTS: Robust scientific evidence, intersectoral coordination, and the presence of "champions" boosted progress in tobacco control (facilitators). The main barriers were the incomplete implementation of the World Health Organization-Framework Convention on Tobacco Control (WHO-FCTC) and MPOWER package and lack of commitment ("political will") by government decision makers and legislators, misinformation about the effects of tobacco taxes, and strong tobacco industry interference. CONCLUSIONS: Robust evidence is necessary but not sufficient to advance the implementation of the MPOWER (WHO-FCTC) actions. To achieve tobacco tax increases and public policies that protect people from unhealthy products in general, the implementation of policies or legal frameworks against industry interference in the development of public policies is imperative. IMPLICATIONS: By analyzing the barriers and facilitators to increasing the tobacco tax in Mexico, this study identifies two key messages: (1) The need to sensitize legislators and the general population to the problem of smoking not only through epidemiological data but also through testimonies that highlight the life experiences and adversities faced by people who smoke. (2) The need for a regulatory framework to prevent industry interference in public affairs and conflicts of interest. The same framework could be very useful for public health policies to control the consumption of ultra-processed food products or alcohol.

A Systematic Review of Qualitative Studies on Factors Associated With Smoking Cessation Among Adolescents and Young Adults.

OBJECTIVE: To summarize findings from qualitative studies on factors associated with smoking cessation among adolescents and young adults. DATA SOURCES: We searched Pubmed, Psychinfo, CINAHL, Embase, Web of Science, and SCOPUS databases, as well as reference lists, for peer-reviewed articles published in English or French between January 1, 2000, and November 18, 2020. We used keywords such as adolescents, determinants, cessation, smoking, and qualitative methods. STUDY SELECTION: Of 1724 records identified, we included 39 articles that used qualitative or mixed methods, targeted adolescents and young adults aged 10-24, and aimed to identify factors associated with smoking cessation or smoking reduction. DATA EXTRACTION: Two authors independently extracted the data using a standardized form. We assessed study quality using the National Institute for Health and Care Excellence checklist for qualitative studies. DATA SYNTHESIS: We used an aggregative meta-synthesis approach and identified 39 conceptually distinct factors associated with smoking cessation. We grouped them into two categories: (1) environmental factors [tobacco control policies, pro-smoking norms, smoking cessation services and interventions, influence of friends and family], and (2) individual attributes (psychological characteristics, attitudes, pre-quitting smoking behavior, nicotine dependence symptoms, and other substances use). We developed a synthetic framework that captured the factors identified, the links that connect them, and their associations with smoking cessation. CONCLUSIONS: This qualitative synthesis offers new insights on factors related to smoking cessation services, interventions, and attitudes about cessation (embarrassment when using cessation services) not reported in quantitative reviews, supplementing limited evidence for developing cessation programs for young persons who smoke. IMPLICATIONS: Using an aggregative meta-synthesis approach, this study identified 39 conceptually distinct factors grouped into two categories: Environmental factors and individual attributes. These findings highlight the importance of considering both environmental and individual factors when developing smoking cessation programs for young persons who smoke. The study also sheds light on self-conscious emotions towards cessation, such as embarrassment when using cessation services, which are often overlooked in quantitative reviews. Overall, this study has important implications for developing effective smoking cessation interventions and policies that address the complex factors influencing smoking behavior among young persons.

Tobacco Imagery in Indian Over-the-Top (OTT) Media and Its Compliance With Existing Tobacco Laws: A Content Analysis.

INTRODUCTION: Over-the-top (OTT) media are internet-based content delivery systems offering media services to the viewers bypassing the traditional broadcasting platforms. The OTT media, with limited regulatory oversight, can serve as a source of exposure to tobacco-promoting content. AIMS AND METHODS: This study analyzed the depiction of tobacco imagery in Indian OTT programs and assessed their compliance with existing Indian tobacco control policies. We conducted a content analysis of 28 purposively sampled OTT exclusive programs (14 movies and 14 web series) in India. Breathe California method was used to code the OTT content for tobacco imagery. We assessed the prevalence of tobacco imagery, its duration per episode or program, product placements, and brand appearances. We also evaluated OTT programs adherence to existing tobacco control policies in India. RESULTS: Tobacco imagery was identified in all of the web series and most OTT-exclusive movies. On average the web series depicted seven incidents of tobacco imagery per episode, whereas there were close to 19 incidents of tobacco imagery per movie. Ten minutes of OTT programming (including movies and web series) had on average 8.40 s of tobacco imagery. None of the OTT programs studied fully complied with Indian tobacco control policies. CONCLUSIONS: Depiction of tobacco imagery in OTT exclusive programs is common in India. Streaming platforms need to comply with existing tobacco control policies. Furthermore, there is a need to strengthen these policies and strictly enforce them to ensure tobacco-free mass media. IMPLICATIONS: India has more than 267 million tobacco users and accounts for the largest share of smokeless tobacco use globally. OTT platforms are largely unregulated and are considered drivers for global tobacco use. This is one of the few studies examining tobacco imagery in Indian OTT content, reporting the gaps in tobacco control policies in India. This study documents the product placement of smokeless tobacco, duration of exposure to tobacco imagery, and empirically report the compliance of OTT platforms with Indian tobacco control policies. The study findings can aid in strengthening tobacco control policies in India.

Evaluating The Real Cost Digital and Social Media Campaign: Longitudinal Effects of Campaign Exposure on E-cigarette Beliefs.

INTRODUCTION: Over the past decade, youth e-cigarette use has risen exponentially. At the same time, digital media use increased markedly while the use of traditional broadcast TV declined. In response, the U.S. Food and Drug Administration's The Real Cost public education campaign shifted to communicating the harms of e-cigarette via primarily digital and social platforms. This study evaluated longitudinal associations between exposure to campaign advertisements and changes in campaign-specific beliefs among US youth. METHODS: A nationally representative longitudinal cohort of youth (aged 11-16 years at baseline) was surveyed five times. Building on earlier work, we analyzed data from the last three waves (April-July 2020; January-April 2021; and August-October 2021; N = 2625). We assessed self-reported exposure to six ads and agreement with 11 beliefs that were each targeted by one or more ads. Eleven weighted panel regression models assessed whether ad exposure predicted changes in campaign-specific beliefs over time. RESULTS: We observed significant associations between ad exposure and increases in at least one campaign-specific belief for five of the six ads. Across the 11 beliefs, we observed associations between increased exposure and increases in 6 beliefs related to e-cigarettes and toxic metals, lung damage, dangerous ingredients, anxiety, cigarette use, and disappointing important people. CONCLUSIONS: We found evidence that self-reported exposure to this digital and social media campaign was successful at influencing youth, providing support for the effectiveness of the campaign's adaption to address youth's changes in tobacco and media use habits. IMPLICATIONS: The Food and Drug Administration's The Real Cost public education campaign educates youth about the dangers of e-cigarette use. This study evaluates longitudinal associations between exposure to The Real Cost's advertisements and changes in campaign-specific beliefs among youth. Considering evolving trends in youth media consumption, the campaign adapted its media approach to increase delivery across digital and social media platforms. Our findings indicate that the campaign reached its intended audience and increased youth beliefs around the harm of e-cigarettes and the consequences of e-cigarette use, offering evidence for the effectiveness of digital and social media youth prevention efforts within a fragmented digital environment.

Promising Themes for Electronic Cigarette Prevention Campaigns for Youth and Young Adults.

INTRODUCTION: Electronic cigarettes (e-cigarettes) are the most widely used tobacco product by youth and young adults in the United States. Effective prevention campaigns require the identification of appropriate content focus for message construction. AIMS AND METHODS: A sample of 2622 youth and young adults ages 15-24 were recruited through social media advertisements and completed an online survey. Respondents reported current e-cigarette use or intention to use if not currently using. They also indicated agreement or disagreement with 75 e-cigarette-related beliefs representing 16 themes. The relative promise of each theme/belief for campaign messaging was investigated by examining its association with the behavior/intention outcomes and the opportunity for positive change in its distribution (room to move). RESULTS: All themes showed significant associations with the behavior (ORs = 2.49-19.04) and intention (ORs = 2.21-6.11) outcomes. Room to move for themes ranged from 32.9% to 96.3% in behavior analysis and 15.6-93.9% in intention analysis. A normed relative promise index (M = 50, SD = 17) showed flavors (72), comparison to cigarettes (69), and relaxation and mental health (68) as the top ranked themes. Subgroup analyses by demographics revealed few differences. Results on the belief level were largely consistent with those on the theme level. CONCLUSIONS: Data from this study provide timely evidence for the relative value of various themes/beliefs as potential targets for message development in e-cigarette prevention campaigns. The final selection of target themes/beliefs requires consideration of openness to persuasion, which may be informed by additional testing. IMPLICATIONS: Electronic cigarettes (e-cigarettes) are the most widely used tobacco products among youth and young adults in the United States. This study adds new evidence on the relative promise of a wide range of e-cigarette beliefs and belief clusters (themes) as potential targets for message development in educational campaigns. This evidence is important to consider in future campaign efforts directed at the youth and young adult populations in the United States.

Exposure to cigarette taxes as a teenager and the persistence of smoking into adulthood.

Are teenage and adult smoking causally related? Recent anti-tobacco policy is predicated on the assumption that preventing teenagers from smoking will ensure that fewer adults smoke, but direct evidence in support of this assumption is scant. Using data from three nationally representative sources and instrumenting for teenage smoking with cigarette taxes experienced at ages 14-17, we document a strong positive relationship between teenage and adult smoking: deterring 10 teenagers from smoking through raising cigarette taxes roughly translates into 5 fewer adult smokers. We conclude that efforts to reduce teenage smoking can have long-lasting consequences on smoking participation and, presumably, health.

Advancing progress on tobacco control in low-income and middle-income countries through economic analysis.

BACKGROUND: More than 80% of the world's 1.3 billion tobacco users live in low-income and middle-income countries (LMICs), where progress to address tobacco and its harms has been slow. The perception that tobacco control detracts from economic priorities has impeded progress. The Secretariat of the WHO Framework Convention on Tobacco Control (FCTC) is leading the FCTC 2030 project, which includes technical assistance to LMICs to analyse the economic costs of tobacco use and the benefits of tobacco control. METHODS: The Secretariat of the WHO FCTC, United Nations Development Programme and WHO supported 21 LMICs between 2017 and 2022 to complete national investment cases to guide country implementation of the WHO FCTC, with analytical support provided by RTI International. These country-level cases combine customised estimates of tobacco's economic impact with qualitative analysis of socio-political factors influencing tobacco control. This paper overviews the approach, observed tobacco control advancements and learnings from 21 countries: Armenia, Cabo Verde, Cambodia, Chad, Colombia, Costa Rica, El Salvador, Eswatini, Georgia, Ghana, Jordan, Laos, Madagascar, Myanmar, Nepal, Samoa, Sierra Leone, Sri Lanka, Suriname, Tunisia and Zambia. RESULTS: Tobacco control advancements in line with investment case findings and recommendations have been observed in 17 of the 21 countries, and many have improved collaboration and policy coherence between health and economic stakeholders. CONCLUSIONS: Tobacco control must be seen as more than a health concern. Tobacco control leads to economic benefits and contributes to sustainable development. National investment cases can support country ownership and leadership to advance tobacco control.

Evolving methodology of national tobacco control investment cases.

BACKGROUND: This article describes an investment case methodology for tobacco control that was applied in 36 countries between 2017 and 2022. METHODS: The WHO Framework Convention on Tobacco Control (FCTC) investment cases compared two scenarios: a base case that calculated the tobacco-attributable mortality, morbidity and economic costs with status quo tobacco control, and an intervention scenario that described changes in those same outcomes from fully implementing and enforcing a variety of proven, evidence-based tobacco control policies and interventions. Health consequences included the tobacco-attributable share of mortality and morbidity from 38 diseases. The healthcare expenditures and the socioeconomic costs from the prevalence of those conditions were combined to calculate the total losses due to tobacco. The monetised benefits of improvements in health resulting from tobacco control implementation were compared with costs of expanding tobacco control to assess returns on investment in each country. An institutional and context analysis assessed the political and economic dimensions of tobacco control in each context. RESULTS: We applied a rigorous yet flexible methodology in 36 countries over 5 years. The replicable model and framework may be used to inform development of tobacco control cases in countries worldwide. CONCLUSION: Investment cases constitute a tool that development partners and advocates have demanded in even greater numbers. The economic argument for tobacco control provided by this set of country-contextualised analyses can be a strong tool for policy change.

Interpreting results, impacts and implications from WHO FCTC tobacco control investment cases in 21 low-income and middle-income countries.

BACKGROUND: Tobacco control investment cases analyse the health and socioeconomic costs of tobacco use and the benefits that can be achieved from implementing measures outlined in the WHO Framework Convention on Tobacco Control (WHO FCTC). They are intended to provide policy-makers and other stakeholders with country-level evidence that is relevant, useful and responsive to national priorities and policy context. METHODS: This paper synthesises findings from investment cases conducted in Armenia, Cabo Verde, Cambodia, Chad, Colombia, Costa Rica, El Salvador, Eswatini, Georgia, Ghana, Jordan, Laos, Madagascar, Myanmar, Nepal, Samoa, Sierra Leone, Sri Lanka, Suriname, Tunisia and Zambia. We examine annual socioeconomic costs associated with tobacco use, focusing on smoking-related healthcare expenditures, the value of lives lost due to tobacco-related mortality and workplace productivity losses due to smoking. We explore potential benefits associated with WHO FCTC tobacco demand-reduction measures. RESULTS: Tobacco use results in average annual socioeconomic losses of US$95 million, US$610 million and US$1.6 billion among the low-income (n=3), lower-middle-income (n=12) and upper-middle-income countries (n=6) included in this analysis, respectively. These losses are equal to 1.1%, 1.8% and 2.9% of average annual national gross domestic product, respectively. Implementation and enforcement of WHO FCTC tobacco demand-reduction measures would lead to reduced tobacco use, fewer tobacco-related deaths and reduced socioeconomic losses. CONCLUSIONS: WHO FCTC tobacco control measures would provide a positive return on investment in every country analysed.

Equity implications of tobacco taxation: results from WHO FCTC investment cases.

BACKGROUND: Across time, geographies and country income levels, smoking prevalence is highest among people with lower incomes. Smoking causes further impoverishment of those on the lower end of the income spectrum through expenditure on tobacco and greater risk of ill health. METHODS: This paper summarises the results of investment case equity analyses for 19 countries, presenting the effects of increased taxation on smoking prevalence, health and expenditures. We disaggregate the number of people who smoke, smoking-attributable mortality and cigarette expenditures using smoking prevalence data by income quintile. A uniform 30% increase in price was applied across countries. We estimated the effects of the price increase on smoking prevalence, mortality and cigarette expenditures. RESULTS: In all but one country (Bhutan), a one-time 30% increase in price would reduce smoking prevalence by the largest percent among the poorest 20% of the population. All income groups in all countries would spend more on cigarettes with a 30% increase in price. However, the poorest 20% would pay an average of 12% of the additional money spent. CONCLUSIONS: Our results confirm that health benefits from increases in price through taxation are pro-poor. Even in countries where smoking prevalence is higher among wealthier groups, increasing prices can still be pro-poor due to variable responsiveness to higher prices. The costs associated with higher smoking prevalence among the poor, together with often limited access to healthcare services and displaced spending on basic needs, result in health inequality and perpetuate the cycle of poverty.

Association between Tobacco Industry Interference Index (TIII) and MPOWER measures and adult daily smoking prevalence rate in 30 countries.

BACKGROUND: This study aimed to investigate the impact of tobacco industry interference on the implementation and management of tobacco control and the tobacco epidemic using the Tobacco Industry Interference Index (TIII) and MPOWER-a package of measures for tobacco control-and adult daily smoking prevalence in 30 countries. METHODS: The TIII was extracted from the Global Tobacco Industry Interference Index 2019 and Global Center for Good Governance in Tobacco Control (GGTC). MPOWER measures and adult daily smoking prevalence rate were extracted from the World Health Organization (WHO) report on the global tobacco epidemic in 2021. We assessed the ecological cross-lagged association between TIII and MPOWER scores and between TIII and age-standardized prevalence rates for adult daily tobacco users. RESULTS: Tobacco industry interference was inversely correlated with a country's package of tobacco control measures (ß = -0.088, P = 0.035). The TIII was correlated with weaker warnings about the dangers of tobacco (ß = -0.016, P = 0.078) and lack of enforcement of bans on tobacco advertising promotion and sponsorship (ß = -0.023, P = 0.026). In turn, the higher the TIII, the higher the age-standardized prevalence of adult daily tobacco smokers for both sexes (ß = 0.170, P = 0.036). Adult daily smoking prevalence in males (ß = 0.417, P = 0.004) was higher in countries where the tobacco industry received incentives that benefited its business. CONCLUSION: Where the interference of the tobacco industries was high, national compliance with the Framework Convention on Tobacco Control (FCTC) was lower, and the prevalence of adult daily smokers higher. National governments and global society must work together to minimize the tobacco industry's efforts to interfere with tobacco control policies.

Global smoking-related deaths averted due to MPOWER policies implemented at the highest level between 2007 and 2020.

BACKGROUND: In response to the harm caused by tobacco use worldwide, the World Health Organization (WHO) World Health Assembly actioned the WHO Framework Convention on Tobacco Control (FCTC) in 2005. To help countries meet their FCTC obligations, the WHO introduced in 2008 the MPOWER policy package and by 2020 the FCTC had been ratified by 182 parties. The package consists of six evidence-based demand reduction smoking cessation policies to assist countries to achieve best practice. We used published evaluation results and replicated the published model to estimate current policy achievement and demonstrate the impact and equity of the MPOWER policy package in reducing the global number of smokers and smoking-attributable deaths (SADs) between 2007 and 2020. METHODS: We replicated an evaluation model (the Abridged SimSmoke model) used previously for country impact assessments and validated our replicated reduction in SADs for policies between 2014 and 2016 against the published results. The replicated model was then applied to report on the country level SADs averted from achieving the highest level of implementation, that is best practice in MPOWER policies, between 2016 and 2020. The latest results were then combined with past published results to estimate the reduction in SADs since the commencement of the MPOWER policy package. Country level income status was used to investigate the equity in the uptake of MPOWER policies worldwide. RESULTS: Identical estimates for SADs in 41 out of 56 MPOWER policies implemented in 43 countries suggested good agreement in the model replication. The replicated model overestimated the reduction in SADs by 159,800 (1.5%) out of a total of 10.5 million SADs with three countries contributing to the majority of this replication discrepancy. Updated analysis estimated a reduction of 8.57 million smokers and 3.37 million SADs between 2016 and 2020. Between 2007 and 2020, 136 countries had adopted and maintained at least one MPOWER policy at the highest level which was associated with a reduction in 81.0 million smokers and 28.3 million SADs. Seventy five percent of this reduction was in middle income countries, 20% in high income and less than 5% in low income countries. CONCLUSIONS: Considerable progress has been made by MPOWER policies to reduce the prevalence of smokers globally. However, there is inequality in the implementation and maintenance, reach and influence, and the number of SADs averted. Future research to modify the model could provide a more comprehensive evaluation of past and future progress in tobacco control policies, worldwide.

Exposure to pro-tobacco and anti-tobacco media messages and events and smoking behaviour among adolescents in Gambia.

BACKGROUND: Despite the widespread prevalence of adolescent smoking in Gambia, a West African country, there is limited research exploring the relationships between exposure to pro-tobacco and anti-tobacco media messages and events and smoking behaviour among young people. This study investigates the interplay of these exposures and smoking behaviour among 11-17-year-old adolescents in Gambia. METHODS: Secondary data analysis was conducted using the 2017 Gambia Global Youth and Tobacco Survey (GYTS), which included a total of 9,127 respondents. Descriptive and inferential analyses, including proportions, Pearson's chi-squared tests, and multivariable logistic regression models, were employed to estimate adjusted odds ratios (aOR) with 95% confidence intervals (CI). RESULTS: The final model revealed significant associations between exposure to anti-tobacco media messages and events and smoking behaviour. Adolescents exposed to anti-tobacco media messages had a 29% increased odds of smoking (aOR 1.29,CI = 1.08,1.53) compared to those unexposed, while exposure to anti-tobacco media events showed a 31% increased odds (aOR 1.31,CI = 1.09,1.59) compared to those unexposed. Exposure to pro-tobacco messages, such as witnessing tobacco use on TV (aOR 1.41, CI = 1.17,1.69) and owning objects with tobacco brand logos (aOR 1.49,CI = 1.19,1.86), was associated with higher odds of smoking. Covariates, including sex, age, and exposure to smoking behaviour by significant others, also demonstrated associations with smoking behaviour. Notably, male respondents showed significantly higher odds of smoking (aOR = 4.01,CI = 3.28,4.89) compared to females. Respondents aged 15 years and older had increased odds of smoking (aOR = 1.47,CI = 1.22,1.76) compared to those below 15 years old. Those whose fathers smoke displayed higher odds of smoking (aOR = 1.35, CI = 1.04,1.76) compared to individuals with non-smoking parents. Additionally, those whose closest friends smoke showed remarkably higher odds of smoking (aOR = 2.87,CI = 2.37, 3.48) compared to those without such influence. CONCLUSION: This study underscores the significant impact of exposure to both anti-tobacco and pro-tobacco media messages and events on smoking behaviour among adolescents in Gambia. However, pro-tobacco messages had a greater influence on smoking prevalence than anti-tobacco messages and events. Understanding these associations is crucial for devising effective public health interventions aimed at reducing tobacco use in this population.
