The health and economic burden of smoking in 12 Latin American countries and the potential effect of increasing tobacco taxes: an economic modelling study

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.

Economic priorities over population health: A political dilemma in addressing noncommunicable diseases in developing countries

The world is observing a rapid shift in the burden of diseases with predominance of noncommunicable diseases (NCDs). NCDs contribute to 41 million deaths which is equivalent to 74% of all death globally per year. There is ongoing debate on the approaches to reduce public exposure to NCDs' modifiable risk factors which are of economic potential. As the World Health Organization and the World Bank recommend the implementation of taxation to these factors, still questions arise on the effectiveness, sustainability, and practicality of this strategy. With the ongoing transition globally from consumption of natural to processed foods, it is important to counter-check the best interventions on how to protect people from unhealthy eating behaviors. While taxation on unhealthy food and other products like tobacco has been recommended as one among interventional approaches, its effectiveness on sugar sweetened beverages is not reliable compared to approaches that increase self-control. Despite the perceived economic benefits of tobacco and sugar sweetened products, there is detrimental implication in terms of public health. The introduction of taxation which favors public health faces challenges due to conflict of interest from government authorities and other stakeholders. The intertwined relationship between public health and economic development becomes more obvious during implementation of preventive and control measures against modifiable risk factors for NCDs. It is evident that reaching a balanced rational decision on choosing between economic growth and public health is difficult. Countries should enhance both local and international intersectoral and multisectoral approaches in creating integrative policies which include health component in all non-health policies including economic policies so as to harmonize public health and economic growth during this era of extensive globalization.

Association of cigarette excise taxes and clean indoor air laws with change in smoking behavior in the United States: a Markov modeling analysis

The rates of cigarette smoking in the United States have declined over the past few decades in parallel with increases in cigarette taxes and introduction of more stringent clean indoor air laws. Few longitudinal studies have examined association of taxes and clean indoor air policies with change in smoking nationally. This study examined the association of state and local cigarette taxes and clean indoor laws with change in smoking status of 18,499 adult participants of the longitudinal 2010-2011 Tobacco Use Supplement of the Current Population Survey over a period of 1 year. Every $1 increase in cigarette excise taxes was associated with 36% higher likelihood of stopping smoking among regular smokers. We found no association between clean indoor air laws and smoking cessation nor between taxes and clean indoor air laws with lower risk of smoking initiation. Cigarette taxes appear to be effective anti-smoking policies. Some state and local governments do not take full advantage of this effective policy measure.

Exploring gender disparities in the disease and economic tobacco-attributable burden in Latin America

Introduction

Tobacco use has significant health consequences in Latin America, and while studies have examined the overall impact, the gender-specific effects have not been thoroughly researched. Understanding these differences is crucial for effective tobacco control policies. The objective of this study was to explore the differences in tobacco-attributable disease and economic burden between men and women in Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico, and Peru.

Methods

We used a previously validated economic model to quantify the impact of tobacco-related illnesses, including morbidity, mortality, healthcare costs, productivity losses, informal care expenses, and DALYs, by gender and age. We utilized data from national surveys, records, studies, and expert opinions to populate the model.

Results

In 2020, there were 351,000 smoking-attributable deaths. Men accounted for 69% and women 31%. Ecuador and Mexico had the highest male-to-female death ratio, while Peru and Chile had the smallest disparities. 2.3 million tobacco-related disease events occurred, with 65% in men and 35% in women. Ecuador and Mexico had higher disease rates among men, while Peru had a more balanced ratio. Regarding DALYs, men lost 6.3 million due to tobacco, while women lost 3.3 million, primarily from COPD, cardiovascular disease, and cancer. Brazil and Mexico had the highest DALY losses for both genders. Costa Rica had a lower male-to-female tobacco use prevalence ratio but ranked second in deaths, disease events, and DALYs attributed to tobacco. Colombia had a unique pattern with a male-to-female death ratio of 2.08 but a higher ratio for disease events. The health systems spent $22.8 billion to treat tobacco-attributable diseases, with a male-to-female cost ratio 2.15. Ecuador showed the greatest gender cost difference, while Peru had the lowest. Productivity loss due to tobacco was $16.2 billion, with Ecuador and Mexico exhibiting the highest gender disparities and Peru the lowest. Informal care costs amounted to $10.8 billion, with men incurring higher costs in Ecuador, Costa Rica, and Mexico.

Discussion

Tobacco causes significant health and economic burdens in Latin America, with gender-based differences. There is a need for gender-disaggregated data to improve tobacco control policies.

Early developmental risks for tobacco addiction: A probabilistic epigenesis framework

Considerable progress has been made in elucidating the relationships between early life psychobiological and environmental risk factors and the development of tobacco addiction. However, a comprehensive understanding of the heterogeneity in tobacco addiction phenotypes requires integrating research findings. The probabilistic epigenesis meta-theory offers a valuable framework for this integration, considering systemic, multilevel, developmental, and evolutionary perspectives. In this paper, we critically review relevant research on early developmental risks associated with tobacco addiction and highlight the integrative heuristic value of the probabilistic epigenesis framework for this research. For this, we propose a four-level systems approach as an initial step towards integration, analyzing complex interactions among different levels of influence. Additionally, we explore a coaction approach to examine key interactions between early risk factors. Moreover, we introduce developmental pathways to understand interindividual differences in tobacco addiction risk during development. This integrative approach holds promise for advancing our understanding of tobacco addiction etiology and informing potentially effective intervention strategies.

Prevalence and correlates of current cigarette smoking among transgender women in Argentina

Objective

To assess the prevalence of current cigarette smoking among transgender women in Argentina, and to examine the unique associations of current cigarette smoking with demographic and psychosocial factors.

Methods

This study is a secondary data analysis of the TransCITAR - a prospective cohort study of transgender individuals living in Buenos Aires, Argentina - baseline data. The baseline survey collected information on sociodemographic characteristics, perceived health status, depressive symptoms, suicide attempts, current cigarette smoking, alcohol use disorder, and substance use. Participants were also asked about lifetime experiences of physical and sexual violence perpetrated by partners, clients and/or the police, and experiences of gender identity stigma in the past year from healthcare workers and the police. Lastly, participants were asked if they had ever been arrested. Fisher's exact test was used to compare proportions in categorical variables and student t-test was used for continuous variables. Significant associations with current cigarette smoking were tested in a logistic regression model adjusted for all significant associations.

Results

A total of 41.7% of participants (n = 393) reported current cigarette smoking. Compared to their non-smoking counterparts, participants who reported current cigarette smoking (1) had completed less education, (2) were more likely to be born in Argentina, (3) more likely to had migrated to Buenos Aires from other parts of the country, (4) more likely to report a history of sex work, (5) more likely to perceive their health as excellent, (6) more likely to screen positive for hazardous alcohol drinking, (7) more likely to report any substance and cocaine use in the past year, (8) more likely to experience gender identity stigma from the police in the past year, and (9) more likely to being arrested in their lifetime (all p's < 0.05). After controlling for all significant associations, education level of less than high school (AOR = 1.79, 95% CI 1.02-2.12), hazardous drinking (AOR = 2.65, 95% CI 1.30-5.37), and any substance use in the last year (AOR = 2.14, 95% CI 1.16-3.94) were positively and independently associated with current cigarette smoking.

Conclusion

Among transgender women in Argentina, current cigarette smoking was more than double the rate for cisgender women. Current cigarette smoking was associated with education, hazardous drinking, and any drug use. These results will inform future smoking cessation interventions among transgender women in Argentina.

Health, economic and social burden of tobacco in Latin America and the expected gains of fully implementing taxes, plain packaging, advertising bans and smoke-free environments control measures: a modelling study

OBJECTIVE

To investigate the tobacco-attributable burden on disease, medical costs, productivity losses and informal caregiving; and to estimate the health and economic gains that can be achieved if the main tobacco control measures (raising taxes on tobacco, plain packaging, advertising bans and smoke-free environments) are fully implemented in eight countries that encompass 80% of the Latin American population.

DESIGN

Markov probabilistic microsimulation economic model of the natural history, costs and quality of life associated with the main tobacco-related diseases. Model inputs and data on labour productivity, informal caregivers' burden and interventions' effectiveness were obtained through literature review, surveys, civil registrations, vital statistics and hospital databases. Epidemiological and economic data from January to October 2020 were used to populate the model.

FINDINGS

In these eight countries, smoking is responsible each year for 351 000 deaths, 2.25 million disease events, 12.2 million healthy years of life lost, US$22.8 billion in direct medical costs, US$16.2 billion in lost productivity and US$10.8 billion in caregiver costs. These economic losses represent 1.4% of countries' aggregated gross domestic products. The full implementation and enforcement of the four strategies: taxes, plain packaging, advertising bans and smoke-free environments would avert 271 000, 78 000, 71 000 and 39 000 deaths, respectively, in the next 10 years, and result in US$63.8, US$12.3, US$11.4 and US$5.7 billions in economic gains, respectively, on top of the benefits being achieved today by the current level of implementation of these measures.

CONCLUSIONS

Smoking represents a substantial burden in Latin America. The full implementation of tobacco control measures could successfully avert deaths and disability, reduce healthcare spending and caregiver and productivity losses, likely resulting in large net economic benefits.

Projected Global Trends in Ischemic Stroke Incidence, Deaths and Disability-Adjusted Life Years From 2020 to 2030

BACKGROUND

We projected global trends in ischemic stroke from 2020 to 2030 according to age, sex, and socio-demographic index (SDI) quintile.

METHODS

Estimated annual percentage changes (EAPCs) were used to project trends in the incidence of deaths from and disability-adjusted life years (DALYs) due to ischemic stroke between 2020 and 2030. EAPCs were computed using generalized additive models and data from the Global Burden of Disease study during the 1990 to 2019 period.

RESULTS

The global age-standardized incidence rate of ischemic stroke was projected to increase to 89.32 per 100 000 population in 2030 (EAPC=0.89), whereas the associated global age-standardized death and DALY rates were projected to decrease to 18.28 (EAPC, -3.58) and 500.37 per 100 000 (EAPC=-1.75), respectively, in 2030. The projections indicated a higher age-standardized incidence rate of ischemic stroke among women than among men in 2030 (90.70 versus 87.64 per 100 000). The incidence rate of ischemic stroke was projected to increase across all age groups and SDI quintiles between 2020 and 2030. At the national level, the greatest increase in the age-standardized incidence rate of ischemic stroke between 2020 and 2030 was projected to occur in Cyprus (EAPC=4.16), followed by Palestine (EAPC=3.50) and South Africa (EAPC=2.64). Additionally, the projections suggested increases in the age-standardized death and DALY rates due to ischemic stroke for countries in low-SDI quintiles (EAPC=3.68 and EAPC=5.30, respectively).

CONCLUSIONS

The projections indicated that the incidence rate of ischemic stroke will increase both sexes, all age groups, and all SDI quintiles and in some countries between 2020 and 2030. Furthermore, countries with a low SDI should be aware of potential increases in the age-standardized death and DALY due to ischemic stroke.

Building a House on Sand: How Tobacco Use Is Devouring Resources

BACKGROUND

Tobacco is a major cause of preventable morbidity and mortality, with a considerable economic burden. The purpose of this systematic review was to summarize the evidence on the economic burden of tobacco use by searching national and international databases so as to generate useful information about the costs of tobacco use globally.

METHODS

A systematic search was conducted in Scopus, PubMed, EMBASE, ProQuest, and Web of Science (ISI) databases to identify relevant studies from 1990 to June 2021 using keywords like burden, productivity, indirect cost, direct cost, economic, monetary, expenditure, tobacco, smoking, and cigarettes. Cost estimates were converted into 2020 international dollars per adult.

FINDINGS

A total of 1,781 articles were identified, of which 361 were deemed to be eligible for inclusion. Eventually, 23 articles were found eligible. In most studies, cost estimates were provided using a prevalence-based approach. The highest total cost, as a percentage of gross domestic product (GDP), was reported for South Korea (1.19%). Noteworthy, in all studies, indirect costs accounted for the highest proportion of all costs. The mean total cost amounted to 5,866 million dollars. The direct costs ranged from 179 million dollars in South Korea to 8,156 million dollars in Israel. Meanwhile, the indirect costs ranged from 289 million dollars in Hong Kong to 9,808 million dollars in India.

CONCLUSION

The evidence demonstrated the considerable economic burden of tobacco use in various countries, ranging from 0.33 to 1.19% of the GDP of the investigated countries, indicating the necessity of taking immediate measures. Hence, policies are needed to address the economic burden of smoking.

Perda de Produtividade Atribuída a Neoplasias na América do Sul

Introdução: A carga da doença tem sido empregada em estimativas do impacto das neoplasias, mas a perda de produtividade em razão dessas enfermidades ainda não foi tão explorada. Objetivo: Estimar os anos de vida produtiva perdidos (AVPP) e a perda de produtividade por conta da mortalidade prematura relacionada ao câncer em países da América do Sul em 2019. Método: Dados de mortalidade disponíveis no Global Burden of Disease (GBD) Study 2019 foram usados para estimar a carga de doença atribuível a neoplasias. A perda de produtividade em termos monetários foi calculada usando um proxy da abordagem do capital humano (ACH). Os cálculos foram realizados por sexo, nas faixas etárias de trabalho. Resultados: O total de óbitos foi de 192.240 e o de AVPP, 2.463.155. A perda total de produtividade permanente foi de US$ 4,4 bilhões e US$ 9,4 bilhões em purchasing power parity (PPP) – 0,13% do produto interno bruto (PIB) da região. O custo total por morte foi de US$ 23.617. Houve diferenças significativas entre os países, mas a variação dos cenários mostra robustez das estimativas. Conclusão: O câncer impõe um ônus econômico significativo à América do Sul tanto em termos de saúde quanto de produtividade. Sua caracterização pode subsidiar os governos na alocação de recursos destinados ao planejamento de políticas e execução de intervenções de saúde.

Return on investment of Canadian tobacco control policies implemented between 2001 and 2016

OBJECTIVES

To determine the return on investment (ROI) associated with tobacco control policies implemented between 2001 and 2016 in Canada.

METHODS

Canadian expenditures on tobacco policies were collected from government sources. The economic benefits considered in our analyses (decrease in healthcare costs, productivity costs and monetised life years lost, as well as tax revenues) were based on the changes in smoking prevalence and attributable deaths derived from the SimSmoke simulation model for the period 2001-2016. The net economic benefit (monetised benefits minus expenditures) and ROI associated with these policies were determined from the government and societal perspectives. Sensitivity analyses were conducted to check the robustness of the result. Costs were expressed in 2019 Canadian dollars.

RESULTS

The total of provincial and federal expenditures associated with the implementation of tobacco control policies in Canada from 2001 through 2016 was estimated at $2.4 billion. Total economic benefits from these policies during that time were calculated at $49.2 billion from the government perspective and at $54.2 billion from the societal perspective. The corresponding ROIs were $19.8 and $21.9 for every dollar invested. Sensitivity analyses yielded ROI values ranging from $16.3 to $28.3 for every dollar invested depending on the analyses and perspective.

CONCLUSIONS

This analysis has found that the costs to implement the Canadian tobacco policies between 2001 and 2016 were far outweighed by the monetised value associated with the benefits of these policies, making a powerful case for the investment in tobacco control policies.

Making visible the cost of informal caregivers' time in Latin America: a case study for major cardiovascular, cancer and respiratory diseases in eight countries

BACKGROUND

Informal care is a key element of health care and well-being for society, yet it is scarcely visible and rarely studied in health economic evaluations. This study aims to estimate the time use and cost associated with informal care for cardiovascular diseases, pneumonia and ten different cancers in eight Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico and Peru).

METHODS

We carried out an exhaustive literature review on informal caregivers' time use, focusing on the selected diseases. We developed a survey for professional caregivers and conducted expert interviews to validate this data in the local context. We used an indirect estimate through the interpolation of the available data, for those cases in which we do not found reliable information. We used the proxy good method to estimate the monetary value of the use of time of informal care. National household surveys databases were processed to obtain the average wage per hour of a proxy of informal caregiver. Estimates were expressed in 2020 US dollars.

RESULTS

The study estimated approximately 1,900 million hours of informal care annually and $ 4,300 million per year in average informal care time cost for these fifteen diseases and eight countries analyzed. Cardiovascular diseases accounted for an informal care burden that ranged from 374 to 555 h per year, while cancers varied from 512 to 1,825 h per year. The informal care time cost share on GDP varied from 0.26% (Mexico) to 1.38% (Brazil), with an average of 0.82% in the studied American countries. Informal care time cost represents between 16 and 44% of the total economic cost (direct medical and informal care cost) associated with health conditions.

CONCLUSIONS

The study shows that there is a significant informal care economic burden -frequently overlooked- in different chronic and acute diseases in Latin American countries; and highlights the relevance of including the economic value of informal care in economic evaluations of healthcare.

Associations between healthy lifestyle score and health-related quality of life among Chinese rural adults: variations in age, sex, education level, and income

PURPOSE

This study aimed to investigate the associations between overall lifestyles and HRQoL, as well as the variations in age, sex, education level, and income.

METHODS

A total of 23,402 participants from the Henan rural cohort were included. The healthy lifestyle score (HLS) consists of five lifestyle factors: smoking, alcohol drinking, physical activity, diet, and body mass index. HRQoL was assessed by the EQ-5D-5L questionnaire. The general linear model and Tobit regression model were utilized to assess the associations of HLS with visual analogue score (VAS) and utility index.

RESULTS

Compared with participants with an HLS of 0-2, the corresponding regression coefficients (β) and 95% confidence intervals (CI) of participants with an HLS of 3, 4, and 5 for VAS score were 1.09 (0.59, 1.59), 1.92 (1.38, 2.46), and 2.60 (1.83, 3.37); the corresponding β and 95% CI for utility index were 0.02 (0.01, 0.03), 0.05 (0.03, 0.06), and 0.06 (0.04, 0.07). Notably, these positive associations were greater among the elderly, female, and those with lower education level and average monthly income (p for interaction < 0.05). For instance, the corresponding β and 95% CI of individuals with an HLS of 5 for utility index in average monthly income < 500 RMB, 500-999 RMB, and ≥ 1000 RMB groups were 0.08 (0.05, 0.11), 0.06 (0.03, 0.09), and 0.02 (- 0.00, 0.05).

CONCLUSION

Engaging in healthier lifestyle habits was associated with a higher level of HRQoL, especially in the elderly, females, and those with low education level and average monthly income.

The case for investment in tobacco control: lessons from four countries in the Americas

Objective.

To synthesize learnings from four national tobacco control investment cases conducted in the Americas (Colombia, Costa Rica, El Salvador, Suriname) under the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) 2030 project, to describe results and how national health authorities have used the cases, and to discuss implications for the role of investment cases in advancing tobacco control.

Methods.

We draw on findings from four national investment cases that included 1) a cost-of-illness analysis calculating the health and economic burden of tobacco use, 2) a return-on-investment analysis of implementing key tobacco control demand reduction measures, and 3) a subsidiary analysis of one tobacco control topic of national interest (e.g., equity implications of cigarette taxation). Co-authors reported how cases have been used to advance tobacco control.

Results.

In Colombia, Costa Rica, El Salvador, and Suriname, tobacco use causes social and economic losses equivalent to between 1.0 to 1.8 percent of GDP. Across these countries, implementing WHO FCTC demand reduction measures would save an average of 11 400 lives per year over the next 15 years. Benefits of the measures would far outweigh the costs of implementation and enforcement. Governments are using the cases to advance tobacco control, including to improve tobacco control laws and their enforcement, strengthen tobacco taxation, prioritize tobacco control planning, coordinate a multisectoral response, and engage political leaders.

Conclusions.

National investment cases can help to strengthen tobacco control in countries, including by increasing public and political support for implementation of the WHO FCTC and by informing effective planning, legislation, coordination and financing.

Beneficios del impuesto a los cigarros en México: análisis por sexo y quintil de ingreso

Objetivo.

Estimar los beneficios económicos y en salud, por sexo y por quintil de ingreso, del incremento de los precios de los cigarros mediante impuestos en México.

Métodos.

Con un modelo de costo-efectividad extendido (ECEA, por su sigla en inglés) se estimaron los beneficios distributivos en mujeres y hombres con un escenario de incremento del precio de los cigarros de 44% (de 56,4 pesos mexicanos [MX$] a MX$81,2 por cajetilla), como resultado de triplicar el impuesto específico actual (de MX$0,49/cigarro a MX$1,49/cigarro). El modelo se calibró con fuentes oficiales de información nacional

Resultados.

Con el incremento del impuesto de un peso por cigarro, cerca de 1,5 millones de fumadores abandonarían el consumo (351 300 mujeres y 1,1 millón de hombres). Así, se evitarían aproximadamente 630 000 muertes prematuras atribuibles al tabaco. La reducción de la carga de enfermedad permitiría ahorros para el sector salud cercanos a MX$42 800 millones y evitaría que más de 250 000 personas (entre ellas, 50 200 mujeres fumadoras) cayeran en situación de pobreza. Además, se recaudarían MX$16 200 millones adicionales por año, de los cuales el quintil más bajo aportaría menos de 3% (1% en el caso de las mujeres de menores ingresos).

Conclusiones.

La epidemia de tabaquismo tiene patrones claramente diferenciados entre mujeres y hombres y reflejan un componente de género. Si bien los beneficios del impuesto al tabaco en México tendrían magnitudes relativas al estado actual de la epidemia en cada caso, estos podrían contribuir a un objetivo más amplio de justicia social mediante la reducción de las inequidades de género.

Xenobiotics Delivered by Electronic Nicotine Delivery Systems: Potential Cellular and Molecular Mechanisms on the Pathogenesis of Chronic Kidney Disease

Chronic kidney disease (CKD) is characterized as sustained damage to the renal parenchyma, leading to impaired renal functions and gradually progressing to end-stage renal disease (ESRD). Diabetes mellitus (DM) and arterial hypertension (AH) are underlying diseases of CKD. Genetic background, lifestyle, and xenobiotic exposures can favor CKD onset and trigger its underlying diseases. Cigarette smoking (CS) is a known modified risk factor for CKD. Compounds from tobacco combustion act through multi-mediated mechanisms that impair renal function. Electronic nicotine delivery systems (ENDS) consumption, such as e-cigarettes and heated tobacco devices, is growing worldwide. ENDS release mainly nicotine, humectants, and flavorings, which generate several byproducts when heated, including volatile organic compounds and ultrafine particles. The toxicity assessment of these products is emerging in human and experimental studies, but data are yet incipient to achieve truthful conclusions about their safety. To build up the knowledge about the effect of currently employed ENDS on the pathogenesis of CKD, cellular and molecular mechanisms of ENDS xenobiotic on DM, AH, and kidney functions were reviewed. Unraveling the toxic mechanisms of action and endpoints of ENDS exposures will contribute to the risk assessment and implementation of proper health and regulatory interventions.

Attitudes and practices of tobacco cessation counseling among Saudi dental professionals: A nationwide cross-sectional survey

Background

Dental professionals can play a pivotal role in educating the public about the harmful effects of smoking and encouraging them to quit the habit.

Aim

This study assesses the attitudes and practices of tobacco cessation counseling (TCC) among dental professionals in Saudi Arabia.

Patients and Methods

This questionnaire-based cross-sectional study targeted dentists and dental interns working in government and private sectors in Saudi Arabia. We conducted a descriptive analysis by using SPSS Statistics, version 25.0.

Results

A total of 895 respondents (314 interns and 581 dentists) participated in this survey. Although the majority of respondents (93%) reported that they always ask patients about tobacco habits, only 59% reported recording tobacco habits in patients' files, and only 55% of the respondents reported explaining to patients the harmful effects of tobacco. Around 91% of the participants believe that a dental clinic is an appropriate place for TCC, and 22% believe that TCC has a negative impact on dental practice. Smoking status, work setting, and the number of years since graduation were found to be significantly associated with the respondents' attitudes and practices. Lack of training, time limitations, and lack of confidence were barriers for TCC.

Conclusions

Dental professionals in Saudi Arabia demonstrated relatively positive attitudes but weak practices of TCC. Continuous education and motivation are needed to improve dentists' confidence, attitudes, and willingness for TCC. Integration of tobacco control education in undergraduate curricula is recommended.

Evaluation of the implementation of the Framework Convention on Tobacco Control (FCTC) in Colombia

Evidence-based interventions recommended in the Framework Convention on Tobacco Control of the World Health Organization (WHO FCTC) are subject to implementation factors that might affect their actual effectiveness. The Colombian law enacting key commitments from WHO's FCTC was signed in 2009. This study aims at evaluating the potential impact of the enactment and implementation of these WHO FCTC on four outcomes for tobacco consumption (last-year cigarette smoking prevalence, prevalence of heavy smokers, prevalence of lower-intensity smokers and monthly smoking incidence). We used data from the National Psychoactive Substances Consumption Survey (NPSCS) in 2008 (n = 29 164) and 2013 (n = 32 605), and assessed changes in these four outcomes WHO FCTC using propensity score matching (PSM). Propensity scores were obtained using key socio-demographic variables and by matching through a 'Kernel' estimation. Matching quality tests were performed. The common support for both survey samples was 60 793. Sub-analyses were conducted using a governance index to assess the effect of heterogeneous governance levels, proxying implementation, over the country. We found that cigarette year-prevalence and cigarette month-incidence decreased after matching around 8 and 1.2 percentage points between 2008 and 2013, respectively. Consumption might have shifted, at least partially, from heavy smoking towards lower-intensity smoking. Departments with a higher governance index showed larger reductions of tobacco use, possibly associated to a stronger WHO FCTC implementation. This study highlights the impact that the WHO FCTC had on tobacco consumption in a middle-income country and shows the importance of governance strength as a mediating mechanism for WHO FCTC impact. These results advance current knowledge on the effectiveness of WHO FCTC and shed light on the relevance of governance as a key factor in the WHO FCTC implementation.

The estimated benefits of increasing cigarette prices through taxation on the burden of disease and economic burden of smoking in Nigeria: A modeling study

BACKGROUND

Globally, tobacco consumption continues to cause a considerable burden of preventable diseases. Although the smoking prevalence in Nigeria may be declining over the last years, the absolute number of active smokers remains one of the highest in Africa. Little is known about the disease burden and economic costs of cigarette smoking in Nigeria. Consequently, there is an evidence gap to inform the design and implementation of an effective policy for tobacco control.

METHODS

We applied a microsimulation model to estimate the burden attributable to smoking in terms of morbidity, mortality, disability-adjusted life-years (DALYs), and direct medical costs and indirect costs (e.g., productivity loss costs, informal caregivers' costs). We also modeled the health and economic impact of different scenarios of tobacco price increases through taxes.

RESULTS

We estimated that smoking is responsible for approximately 29,000 annual deaths in Nigeria. This burden corresponds to 816,230 DALYs per year. In 2019, the total economic burden attributable to tobacco was estimated at ₦ 634 billion annually (approximately U$D 2.07 billion). If tobacco cigarettes' prices were to be raised by 50% through taxes, more than 30,000 deaths from smoking-attributable diseases would be averted in 10 years, with subsequent savings on direct and indirect costs of ₦597 billion and increased tax revenue collection of ₦369 billion.

CONCLUSION

In Nigeria, tobacco is responsible for substantial health and economic burden. Increasing tobacco taxes could reduce this burden and produce net economic benefits.

Where to next for countries with high tobacco taxes? The potential for greater control of tobacco pricing through licensing regulation

Optimising the taxation of tobacco products should be among the highest priorities for health and hence economic policy in every country. The WHO Technical Manual on Tobacco Tax Policy and Administration released in April 2021 provides invaluable advice, including 26 best practice recommendations on policy design, administrative efficiency and addressing industry tactics to circumvent tobacco tax increases. Introducing and increasing tobacco taxes is the most important tobacco control measure for any jurisdiction. The effects of simple tax structures, high tax levels, and frequent above-inflation increases in specific excise duties can be enhanced through strict controls on packaging (including pack size), product design, and discounting. However, even with such measures, tobacco companies can continue to undermine the effectiveness of tax policy by offering some products in their ranges at very low prices, as well as gradually and selectively increasing the prices of some but not all products after tax increases. This paper is aimed at policymakers in countries that have already adopted best practice tax policy. It explores the idea of wholesale price capping combined with retail licensing to address the problems of brand proliferation, dispersion of prices, cushioning and strategic under/overshifting of tax increases, thereby radically and sustainably increasing the effectiveness of tobacco tax policy while also raising additional tax revenue for governments by reducing industry profitability.

The distributional effects of tobacco tax increases across regions in Mexico: an extended cost-effectiveness analysis

BACKGROUND

Several studies have shown the beneficial effects of tobacco fiscal policy, but distributional effects have been less examined, especially at the subnational level. The objective of this study is to analyse the distributional effects of a one-peso tobacco tax increase (roughly equivalent to tripling the current excise tax) on health, poverty, and financial outcomes at the subnational level in Mexico.

METHODS

We employ an extended cost-effectiveness analysis that estimates life-years gained, smoking attributable deaths averted, treatment costs averted, number of persons avoiding poverty and catastrophic health expenditures, and additional tax revenues by income group across five regions.

RESULTS

With the one-peso tax increase (or 44% price increase), about 1.5 million smokers would quit smoking across the five regions, resulting in nearly 630 thousand premature deaths averted and 12.6 million life years gained. The bottom income quintile would gain three times more life years gains than the top quintile (ratio 3:1), and the largest gain for the most deprived would occur in the South (ratio 19:1), the region with the highest poverty incidence. Costs averted and additional tax revenues would reach 44.6 and 16.2 billion pesos, respectively. Moreover, 251 thousand individuals would avoid falling into poverty, including 53.2 in the lowest income quintile, and 563.9 thousand would avoid catastrophic health expenditures. Overall, the bottom income group would obtain 26% of the life years gained and 24% of the cost averted, while only paying 3% of the additional tax revenue.

CONCLUSIONS

The most significant gains from a substantial cigarette price increase would be for the poorest 20%, especially in the South, the most impoverished region of Mexico. Therefore, tobacco taxes are an opportunity for governments to advance in equity and towards the achievement of sustainable development goals on non-communicable diseases.

Changes in parental smoking behavior and children's health status in Chile

Studies on parental smoking behavior have mostly been conducted for developed countries and show that current parental smoking is negatively associated with children's current health. Using four waves of a Chilean longitudinal survey (Encuesta de Protección Social), we estimate probit and ordinary least squares models relating parents' self-report of their children's current health status to several covariates, including current parental smoking status and change (transitions) in parental smoking status across the waves of the survey. The data were collected in the years 2004, 2006, 2009, and 2015. The working sample includes 25,052 observations. The study revealed that parents' self-report of their children's current health status is strongly associated with current and past parental smoking status. Parents who smoke have an increased 11.17% probability of reporting that their children are in fair, poor, or very poor health status, when compared to non-smoking parents. The effect is stronger if the smoker is the mother, and it is exacerbated if she is less educated or unemployed/inactive. In addition, quitting smoking has a significant positive effect on children's reported health status, which is greater if the mother quits smoking. Cessation among mothers who are unemployed or inactive is also associated with a more positive assessment of their children's health status. The findings suggest that cessation programs may have health benefits not only for smoking parents, but also for their children. Improving coverage or establishing a national cessation program may have important present and future effects on population health and well-being.

Optimizing Tobacco Advertising Bans in Seven Latin American Countries: Microsimulation Modeling of Health and Financial Impact to Inform Evidence-Based Policy

INTRODUCTION

In Latin America, tobacco smoking prevalence is between 6.4% and 35.2%. Governments have been making efforts to support the regulation of advertising and, in many cases, banning advertising and promotion of tobacco altogether. The objective of this study was to evaluate the potential impact on health and economic outcomes of optimizing a ban on tobacco advertising and sponsorship in Argentina, Bolivia, Brazil, Chile, Colombia, Mexico, and Peru.

METHODS

We built a probabilistic microsimulation model, considering natural history, direct health system costs, and quality of life impairment associated with main tobacco-related diseases. We followed individuals in hypothetical cohorts and calculated health outcomes on an annual basis to obtain aggregated 10-year population health outcomes (deaths, events, healthy years of life) and costs. To populate the model, we performed a rapid review of literature to calculate intervention effectiveness.

RESULTS

With current policies, over 10 years, in Argentina, Bolivia, Brazil, Chile, and Colombia a total of 50,000 deaths and 364,000 disease events will be averted, saving $7.2 billion. If the seven countries strengthened their policies and implemented a comprehensive ban with 100% compliance, 98,000 deaths and 648,000 events would be averted over 10 years, saving almost $15 billion in healthcare costs.

CONCLUSIONS

Optimizing a ban on tobacco advertising and sponsorship would substantially reduce deaths, diseases, and health care costs attributed to smoking. Latin American countries should not delay the full implementation of this strategy.
