Background: This study analyses the relationship between healthcare expenditure and development indices of health in Nigeria, such as life expectancy, infant mortality, and maternal mortality. Although healthcare expenditure has improved following the Millennium Development Goals, Nigeria continues to lag in converting this investment into significant improvements in healthcare outcomes. This motivates the study of the performance of various expenditure structures. Method: The study utilises annual time series data from reputable organisations such as the Central Bank of Nigeria and the World Health Organisation. The Least Squares (LS) and Autoregressive Distributed Lag (ARDL) cointegration approaches estimate short-run and long-run relationships between health expenditure and health indicators. Findings: The findings reveal that public health expenditure is positively related to life expectancy and negatively related to infant and maternal mortality, though the latter relationships are not always statistically significant. Private health expenditure is positively associated with life expectancy and negatively with mortality. Foreign health assistance and health expenditure per capita show weak associations with life expectancy and mortality rates. Out-of-pocket spending is negatively correlated with life expectancy and positively with infant and maternal mortality. Population growth is strongly linked to increased life expectancy and reduced mortality rates. Conclusion: The study discovers that private health spending is a more significant determinant of increasing Nigeria's health outcomes over public spending, and out-of-pocket spending is a reverse determinant. Such conclusions suggest the necessity of greater public-private collaboration and reduction in out-of-pocket dependence to achieve improved development measures of health in Nigeria.
