"More than 800 million people live at 1,500 meters above sea level or higher, with two-thirds of them in Sub-Saharan Africa, and Asia. These two regions host most of the world's stunted children so it is important to understand the role that altitude plays in growth" said IFPRI Senior Research Fellow and co-author of the study, Kalle Hirvonen.

"If children living at altitude are, on average, more stunted than their peers at sea level, then a more significant effort to address high altitude stunting is needed."
