Despite being the most cost-effective tobacco control policy, tobacco taxation is the least implemented component of the World Health Organization MPOWER package to reduce smoking worldwide. In Mexico, both smoking prevalence and taxation have remained stable for more than a decade. This study aims to provide evidence about the potential effects of taxation to reduce the burden of tobacco-related diseases and the main attributable social costs in Mexico, including informal (unpaid) care costs, which are frequently ignored.

In order to prioritize public policies to reduce the consumption of sugar-sweetened beverages in Argentina, Brazil, El Salvador and Trinidad and Tobago and to identify information gaps related to the burden of disease attributable to their consumption, a policy dialogue was held with government members, civil society organizations, researchers and communicators from Latin American and Caribbean countries. Presentations and deliberative workshops were conducted using semi-structured data collection tools and group discussions. The prioritized interventions were tax increases, front labeling, restriction of advertising, promotion and sponsorship, and modifications regarding the school environment.

Introduction: Tobacco consumption is associated with nearly 30 000 deaths annually in Nigeria alongside other adverse health and economic effects. Our objective was to estimate the health and economic implications of the current cigarette labeling policies (text-only HWs); new health warnings policies in the country (adding graphic health warnings with up to 60% coverage), and plain packaging policy as recommended by the World Health Organization.

Aims And Methods: We used a probabilistic state-transition individual microsimulation model, considering natural history, healthcare costs, and quality-of-life losses associated with main tobacco-attributable diseases; and the potential effects of packaging and labeling policies.

Article Synopsis
  • The study highlights the importance of assessing the cost-effectiveness of health interventions to improve equitable healthcare, noting a lack of standardized methods to determine cost-effectiveness thresholds across different regions.
  • Researchers developed a framework to estimate these thresholds based on health spending per person and life expectancy, analyzing data from 174 countries to identify trends in health expenditures and life expectancy.
  • Findings revealed significant variation in cost-effectiveness thresholds across countries, with the majority of nations having thresholds below one GDP per capita, which suggests that many healthcare interventions are still considered cost-effective by economic standards.
