Health is a critical indicator of human capital that enhances individual productivity. This study analyses the factors affecting human health with a focus on poverty as a primary determinant of health outcomes. Using panel data econometric methods — including fixed effects and pooled OLS models — the study examines the impacts of poverty, income, and education on health in a panel of selected South Asian countries. Results contribute to the literature on human capital formation in developing economies, demonstrating that poverty’s adverse health effects are moderated by income growth and educational attainment. Policy implications centre on the complementarity between poverty reduction, health investment, and human capital development strategies.
