Examining the influence of global smoking prevalence on stroke mortality: insights from 27 countries across income strata
(Springer link, 2024-03-19) Abeysekera, I; De Silva, R; Silva, D; Piumika, L; Jayathilaka, R; Rajamanthri, L
Background This study investigates the influence of Global Smoking Prevalence (GSP) on Stroke Death Rates (SDR) across 27 countries categorized into High-Income Countries (HIC), Upper Middle-Income Countries (UMIC), Lower Middle-Income Countries (LMIC), and Low-Income Countries (LIC). Methods Analysing data from two distinct periods (1990–1999 and 2010–2019), countries exhibiting an increased SDR were selected. The study uses a polynomial regression model, treating income groups as cross-sectional and years as time series data. Results Results from the regression model reveal that 17 countries observed a significant impact of GSP on SDR, with only Turkey, Solomon Islands, and Timor-Leste resulting in negative values. However, the study emphasises that out of all 27 countries, the highest occurrence of the impact of GSP on SDR has been reported in the LMIC stratum for the period under review. Conclusion It is evident that GSP affects the risk of incidence of stroke death, specifically in the LMIC stratum. Furthermore, it has been identified that GSP is a major preventable risk factor affecting global mortality. To mitigate the risk of stroke death attributable to smoking prevalence, necessary preventive steps should be adopted to encourage smoking cessation, and essential policies should be implemented to reduce the burden of SDR.

Global nexus of smoking prevalence, healthcare quality and respiratory cancer mortality: a cross-continental study
(Springer Nature, 2025-10-06) Piumika, L; Silva, D; De Silva, R; Jayathilaka, R; Wickramaarachchi, C; Rajamanthri, L
Background Smoking causes Trachea, Bronchus, and Lung Cancer (TBLC) mortality, depicting a strong correlation,while the quality of healthcare access in countries considerably impacts health outcomes. This study evaluates the differential effect in the interplay between Smoking Prevalence (SP) and health care, employing the Healthcare Access and Quality (HAQ) index towards the TBLC mortality rates across diverse continents and globally. Methods The data covering a 30-year period for 204 countries globally was categorised based on the level of SP (Low, Moderate, High, Critical) and the quality of healthcare access (Poor, Limited, Adequate, Optimal). A two-way ANOVA was utilised to analyse the patterns and variations in TBLC mortality rates across these categories, exploring the interactions between SP and the HAQ Index. Results Distinct patterns were observed in each continent, highlighting the complex interactions between the HAQ Index and SP, which lead to varying health outcomes. The results indicate that regions with an optimal HAQ Index and low SP have lower TBLC death rates, whereas those with a poor HAQ Index and critical SP exhibit higher death rates. Conclusion The findings emphasise the need to address both smoking prevalence and healthcare facilities globally. By improving healthcare access and reducing smoking rates, governments can significantly lower TBLC mortality rates. This study underlines the importance of integrating public health policies that limit smoking prevalence with enhancements in healthcare systems to promote better health and well-being.

Impact of global smoking prevalence on mortality: a study across income groups
(Springer link, 2024-07-04) De Silva, R; Silva, D; Piumika, L; Abeysekera, I; Jayathilaka, R; Rajamanthri, L; Wickramaarachchi, C
Background Smoking significantly contributes to the mortality rates worldwide, particularly in non-communicable and preventable diseases such as cardiovascular ailments, respiratory conditions, stroke, and lung cancer. This study aims to analyse the impact of smoking on global deaths, and its association with mortality across the main income groups. Methods The comprehensive analysis spans 199 countries and territories from 1990 to 2019. The study categorises countries into four income groups: high income, upper middle income, lower middle income, and low income. Results The findings underscore the profound impact of global tobacco smoking on mortality. Notably, cardiovascular disease mortality is notably affected in both upper-middle-income and high-income groups. Chronic respiratory disease mortality rates show a significant impact across all income groups. Moreover, stroke-related mortality is observed in the lower-middle, upper-middle, and high-income groups. These results highlight the pervasive influence of smoking prevalence on global mortality, affecting individuals across various socioeconomic levels. Conclusion The study underscores the critical implications of smoking on mortality rates, particularly in high-income countries. It emphasises the urgency of targeted interventions in these regions to address the specific challenges posed by tobacco smoking on public health. Policy recommendations include implementing prohibitive measures extending to indoor public areas such as workplaces and public transportation services. Furthermore, allocating funds for research on tobacco and health, is imperative to ensure policymakers are consistently informed about emerging facts and trends in this complex domain.
