Child Health and Survival in a Changing World.

Ninety-nine percent of the 5.9 million annual child deaths occur in low and middle-income countries. Undernutrition underlies 45% of deaths. Determinants include access to care, maternal education, and absolute and relative poverty. Socio-political-economic factors and policies tremendously influence health and their determinants. Most deaths can be prevented with interventions that are currently available and recommended for widespread implementation. Millennium Development Goal 4 was not achieved. Sustainable Development Goal 3.2 presents an even more ambitious target and opportunity to save millions of lives; and requires attention to scaling up interventions, especially among the poorest and most vulnerable children.
