The findings show that health expenditure has a positive effect on reducing child mortality only for upper-middle-income and high-income countries, whereas for low-income and lower-middle-income countries, health spending does not have a significant impact on child health status. It is also found that at lower development levels, public health spending has a greater effect on mortality rates than private expenditure, while at high development levels private health expenditure has a positive impact on child mortality. Today, combating this scourge is considered a key policy objective and strategy.
