Publication Open Access Alcohol and Heart - Health Nexus in Lower MiddleIncome Countries: Cardiovascular Risks Study(SLIIT,Business School, 2024) Gamage,J; Oshini, A; Palliyaguru, D; Senarathne,B; Rajamanthri, L; Wichramarachchi, CCardiovascular diseases have become a growing concern in lower-middle-income countries, not only as a public health challenge but also as a critical management issue influencing workforce productivity, absenteeism, and organizational performance. Understanding how lifestyle factors such as alcohol consumption affect cardiovascular health is vital for developing sustainable workplace health strategies. This study examines the impact of alcohol consumption—classified as wine, beer, and spirits—on cardiovascular diseases while incorporating key determinants such as cholesterol, diabetes, obesity, and tobacco use within lower-middle-income countries. Using panel data from 170 countries between 1990 and 2019, this study applies fixed and random effects regression models to explore the relationship between alcohol consumption patterns and cardiovascular disease prevalence. The analysis integrates major lifestyle and health variables to assess their combined impact on national and workforce health outcomes. Findings reveal that alcohol consumption, particularly beer and spirits, has a significant positive association with cardiovascular disease risk, while cholesterol, obesity, and tobacco use further exacerbate these effects. Interestingly, diabetes prevalence demonstrated a negative relationship with cardiovascular disease within lower-middle-income countries. The results underscore the economic and managerial implications of unmanaged lifestyle risks that contribute to lost productivity and healthcare burdens. This study highlights the critical intersection between health behavior and management, suggesting that promoting responsible alcohol consumption and preventive health measures can enhance workforce well-being and productivity. The insights provide valuable guidance for human resource professionals, organizational leaders, and policymakers in designing evidence-based wellness programs, occupational health policies, and strategic interventions aimed at reducing cardiovascular risks in developing economiesPublication Embargo Investigating the Associations Between Alcohol Consumption and Prevalence of Anxiety Using Multiple Correspondence Analysis(Springer, 2025-10-13) Kolonne, T; Mudalige, K; Dissanayaka, G; Rathnayake, K; Jayathilaka, R; Rajamanthri, L; Wickramaarachchi, CThe prevalence of a specific link between alcohol consumption and anxiety is the basis of this study. The primary aim is to identify how different types of alcohol link with different levels of anxiety disorder. This study is based on secondary data spanning two decades from 1990 to 1999 and 2010 to 2019. Before the primary analysis, the variables were categorised relative to their maximum and minimum values to identify countries with high anxiety prevalence. The MCA (multiple correspondence analysis) included four different types of alcohol and the prevalence of anxiety as variables. This methodology was utilised to determine the associations across 189 countries. The results reveal that anxiety rates are rising worldwide, with 17 countries identified to have prevalent high levels of anxiety. Most countries that exhibited a high prevalence of anxiety were based in the European region. The study emphasises a bi-directional association between anxiety and alcohol disorders, with diverse associations for various alcohol categories. Lower levels of consumption of alcoholic drinks with a high percentage of alcohol are associated with a greater incidence of anxiety, except beer, where consuming more beer is associated with a higher anxiety incidence. Similarly, a reciprocal relationship can be identified between these variables. The study emphasises that the consumption of alcohol can be detrimental to mental health and advises anxiety-prone individuals to exercise caution and restraint when imbibing.Publication Open Access Alcohol Consumption and Stroke Mortality: Global Patterns, Risks and Public Health Implications(Springer, 2025-05-07) Kolonne, T; Mudalige, K; Dissanayaka, G; Rathnayake, K; Jayathilaka, R; Rajamanthri, L; Wickramaarachchi, CGlobally, stroke remains a leading cause of mortality and disability, while alcohol consumption continues to vary widely across regions, prompting concern over its health impacts. This study examines the association between different alcoholic beverages and stroke mortality, using secondary data from 1990 to 2020. Alcohol consumption and stroke death rates across 189 countries were categorized into five levels, from very high to very low, and averaged over two periods (1990–1999 and 2011–2020). Multiple Correspondence Analysis (MCA) was applied to assess relationships among four categorical variables. The findings indicate a significant association between very high alcohol consumption and increased stroke mortality, with eight countries showing elevated death rates. Conversely, moderate beer consumption was linked to reduced stroke mortality, suggesting nuanced effects based on beverage type and quantity. These insights offer a foundation for targeted public health policies and emphasize the need for further investigation into the mechanisms driving alcohol-related stroke risks.Publication Open Access Investigating the Associations Between Alcohol Consumption and Prevalence of Anxiety Using Multiple Correspondence Analysis(Springer Nature, 2025-10-13) Kolonne, T; Mudalige, K; Dissanayaka, G; Rathnayake, K; Jayathilaka, R; Rajamanthri, L; Wickramaarachchi, CThe prevalence of a specific link between alcohol consumption and anxiety is the basis of this study.

This study set out to explore the long-term efects of alcohol consumption on anxiety, revealing insights into how alcohol consumption uniquely impact anxiety, aiming to inform mental health and public health approaches. This research paper explores the complex relationship between the prevalence of anxiety and the consumption patterns of wine, beer, and spirits across ffty-two high-income countries with a continental analysis. Method By employing signifcant secondary data taken from the World Health Organization and Our World in Data online databases and covering the period from 1990 to 2019, this study seeks to explore various causality relationships over this period. Its primary objective is to fll the empirical gap in existing research by using Granger causality analysis to reveal the dynamic relationships between the consumption of alcohol and the prevalence of anxiety. This study endeavours to provide a continental analysis of the high-income countries, which allows for including a comprehensive viewpoint in the context of a single investigation. Results The fndings demonstrate a variety of patterns of causality in alcohol consumption and anxiety prevalence in a one-way causal relationship across specifc continents, a bidirectional relationship in others, and no apparent causal relationship in several countries. Conclusion The inference made from the study’s results goes beyond scholarly curiosity; it establishes the foundation for further investigations and the development of customised policies aimed at reducing the mutually reinforcing dangers of alcohol consumption and anxiety disorders.
