    Surviving the first five years: the economic and healthcare determinants of child mortality in Sri Lanka
    (Springer Nature Link, 2025-06-21) Rajapakse, V; Jayathilaka, R
    Background This study investigates the role of economic growth, healthcare investment, immunization coverage, and malnutrition in reducing under-five mortality rates (U5MR) in Sri Lanka. Understanding how these factors interact within socio-economic ecosystems is essential to formulating sustainable strategies to improve child survival outcomes. Methods This study employs multiple linear regression to analyze the statistical associations between economic growth, healthcare investment, immunization, malnutrition, and under-five mortality in Sri Lanka. Using secondary data from the World Bank and UNICEF (2000–2021), U5MR was modeled against economic growth (per capita GDP), government healthcare expenditure (GHE), immunization coverage (DTP1), and malnutrition (MLN), with significance assessed through p-values and model fit via R². Results The multiple linear regression model demonstrated strong explanatory power, accounting for 85% of the variation in under-five mortality (R² = 0.85). Economic growth and immunization coverage were negatively associated with U5MR and found to be statistically significant (p < 0.05 and p < 0.10 respectively), indicating their potential role in reducing child mortality. Malnutrition showed a strong positive association (p < 0.01), emphasizing its continued threat to child health. Although government healthcare expenditure had a negative association, it was not statistically significant, suggesting possible inefficiencies in resource utilization. Conclusion The study highlights the significant role of economic growth, healthcare expenditure, immunization coverage, and nutrition in shaping U5MR trends in Sri Lanka. The findings emphasize the need for targeted policy interventions to enhance child health outcomes and ensure sustainable progress in reducing child mortality.

    The interplay between globalisation and economic growth: a multi-regional analysis
    (Springer Nature Link, 2025-06-10) Athalage, D; Wijesuriya, P; Sandanayaka, I; Rathnayake, D; Jayathilaka, R
    Globalisation is recognised as a prospective dynamic that facilitates the performance and expansion of economies. This study analyses the causal progression between globalisation, its sub dimensions (economic, social and political) and economic growth spanning 97 countries and six regions (Africa, Asia, Europe, North America, Oceania, and South America) covering the period from 1971 to 2021. The Panel Granger causality test is employed as the statistical methodology to comprehend the nexus between globalisation and economic growth. The Granger results reveal bi-directional causal flows between economic growth and globalisation in Asia, North America, and Oceania, along with one-way causal flows in Africa, South America, and Europe. Bidirectional dynamics pertaining to economic globalisation were also revealed in Asia, Africa, Oceania, and Europe. This study recommends the enhancement of regional integration, addressing of structural changes, leveraging the use of technology, and the development of comprehensive globalisation strategies with respect to regions with the intention of reinforcing their globalisation-growth stance, while complementing the Sustainable Development Goals of the United Nations.
