Before revision:  We assess the potential magnitude of this problem by decomposing variation in HAZ from 1,406,609 children from 63 low-and middle-income countries into two components : ( 1) a component shaped by environmental inputs, such as poverty, infectious disease, inadequate sanitation, and healthcare access, and ( 2) a country-specific  starting point that is independent of such inputs.
