Towards a smoke-free world? South America became the first 100% smoke-free subregion in the Americas

Trends and Association between Smoking and the Socio-Demographic Index Among 11 South American Countries, 1990-2019

OBJECTIVES

To examine prevalence trends in the use of smoked tobacco products in 11 South American (SA) countries (i.e., Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, Suriname, Uruguay, and Venezuela) and their association with country-specific socio-demographic index (SDI) over 30 years.

DATA AND METHODS

The estimates of SDI and smoked tobacco prevalence stratified by age, sex, and country were extracted from the Global Burden of Disease Study (1990-2019) on individuals aged 15+. The annual percentage changes (APCs) of trends in country-specific prevalence of smoked tobacco were evaluated using Joinpoint regression. Correlation analysis was also used to explore the association between country-specific prevalence of smoked tobacco and their SDIs, a measure of developmental status considering income per capita, educational attainment, and total fertility rate.

RESULTS

While all SA countries showed an overall decline in smoked tobacco use prevalence between 1990 and 2019 (APCs between -0.52%-and -4.73%; p < 0.05), Bolivia and Ecuador showed a significant increasing trend (APCs of 0.34% and 0.20%). Country-specific SDI was strongly and significantly correlated (rs = -0.99 to -0.85) with smoking prevalence in SA countries, except for Ecuador and Bolivia (rs = 0.16 and 0.36, respectively).

CONCLUSION

In recent decades, most SA countries have experienced a significant reduction in the prevalence of smoked tobacco use, except Ecuador and Bolivia, where smoking rates have risen, showing a direct correlation with SDI. These findings can contribute to the design and implementation of strategies and policies for tobacco prevention and control in the SA region especially within the two affected countries - Ecuador and Bolivia.

The Perfect Storm: Applying the Multiple Streams Framework to Understand the Adoption of a WHO Framework Convention on Tobacco Control-Based Policy in Mexico

BACKGROUND

The aim of this study was to document how Mexico adopted a WHO Framework Convention on Tobacco Control (FCTC)-based national tobacco control law.

METHODS

We analyzed publicly available documents and interviewed 14 key stakeholders. We applied the Multiple Streams Framework (MSF) to analyze these findings.

RESULTS

Previous attempts to approve comprehensive FCTC-based initiatives failed due to a lack of political will, the tobacco industry's close connections to policymakers, and a lack of health advocacy coordination. Applying the MSF reveals increased attention towards collecting and sharing data to frame the severity of the problem (problem stream). The expansion of a coordinated health advocacy coalition and activities led to increased support for desired FCTC policy solutions (policy stream). The election of President López Obrador and legislative changes led to a deep renewed focus on tobacco control (politics stream). These three streams converged to create a policy window to secure a strong FCTC-based initiative on the political agenda that was ultimately passed.

CONCLUSIONS

The Mexican experience illustrates the importance of continued health advocacy and political will in adopting FCTC-based policies. Other countries should follow Mexico's lead by collecting and sharing data through coordinating efforts in order to be prepared to seize political opportunity windows when strong political will is present.

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.

Trends in tracheal, bronchial and lung cancer attributed to smoking in South America: Global Burden of Disease analysis 1990-2019

Objective

To investigate the burden of tracheal, bronchus, and lung (TBL) cancer due to tobacco exposure in the last 30 years in 12 South American countries.

Methods

We used the Global Burden of Disease (GBD) 2019 exposure-response function to analyze the total tobacco, smoking, and secondhand smoke exposure-related TBL cancer deaths and disability-adjusted life years (DALYs), for 12 South American countries, between 1990 and 2019. Metrics were described as absolute numbers or rates per 100 000 individuals. The relative change in burden was assessed by comparing the 1990-1994 to 2015-2019 periods.

Results

In 2019, the all-ages number of TBL cancer deaths and DALYs associated with tobacco exposure in South America was 29 348 and 658 204 in males and 14 106 and 318 277 in females, respectively. Age-adjusted death and DALYs rates for the region in 2019 were 182.8 and 4035 in males and 50.8 and 1162 in females, respectively. In males, 10/12 countries observed relative declines in TBL death rates attributed to tobacco exposure while only 4 countries reduced their mortality in females.

Conclusion

While significant efforts on tobacco control are under place in South America, substantial burden of TBL cancer persists in the region with significant sex-specific disparities. Increased country-specific primary data on TBL cancer and tobacco exposure is needed to optimize healthcare strategies and improve comprehension of regional trends.

State of the literature discussing smoke-free policies globally: A narrative review

Despite the success of the Framework Convention on Tobacco Control (FCTC), most jurisdictions in the world do not have policies that create 100% smoke-free environments in indoor workplaces, indoor public places, public transport, or other public places. We conducted a narrative review of articles that discuss smoke-free policies and describe the state of the current literature. A search of peer-reviewed and gray literature, published between 1 January 2004 and 30 April 2022, was conducted using PubMed and EMBASE databases. We classified articles based on the location of the policy discussed (WHO region, World Bank income classification) and the environment that was being made smoke-free. Insights related to policy development and implementation, as well as compliance and enforcement, were also identified. The search identified 4469 unique citations; 134 articles met the criteria for inclusion and underwent data extraction by two independent coders. The sample included articles published in or about jurisdictions in each WHO region, in high- and low- and mediumincome countries, and articles that discussed policies regulating smoke-free indoor workplaces, indoor public places, public transport, outdoor/quasi-outdoor environments, and other (unspecified) public places. Some important insights from the literature related to smoke-free policy implementation included tobacco industry interference, the important role of civil society, and the need for effective communication, education, and leadership. Enforcement officials' awareness and training, stakeholders' attitudes and beliefs, and understanding social norms were identified as relevant determinants of effective smoke-free policies. There continue to be challenges for implementing smoke-free policies in jurisdictions throughout the globe, in high- and low- and middle-income countries. The literature includes insights to support 100% smoke-free policies in each environment that must be made smoke-free as per the FCTC.
