Abstract

Objective We sought to test hypotheses regarding the principal correlates of child-health performance among African nations based on previous evidence collected at finer spatial scales.
Design Retrospective, cross-sectional study.
Setting All countries in Africa, excluding small-island nations.
Primary and secondary outcome measures We defined a composite child-health indicator for each country comprising the incidence of stunting, deaths from respiratory disease, deaths from diarrhoeal disease, deaths from other infectious disease, and deaths from injuries for children under five years old. We also compiled national-level data for Africa to test the effects of country-level water quality, air pollution, food supply, breastfeeding, environmental performance, per-capita wealth, health-care investment, population density, and governance quality on the child-health indicator.
Results Across nations, child health was lowest when water quality, improved sanitation, air quality, and environmental performance were lowest. There was also an important decline in child health as household size (a proxy for population density) increased. The remaining variables had only weak effects, but in the directions we hypothesized.
Conclusions These results emphasize the importance of continued investment in clean water and sanitation services, measures to improve air quality, and efforts to restrict further environmental degradation, to promote the UN’s Sustainable Development Goal 3 target to “… end preventable deaths of new-borns and children under five” and Goal 6 to “… ensure access to water and sanitation for all” by 2030.
