The Link NCA in Liberia was the first to investigate stunting causal pathways, based on the UNICEF Conceptual Framework for undernutrition. Causal pathways of stunting in this context were rooted in low access to water, non-optimal sanitation practices, and low access to food. The current framework of analysis for the Link NCA was appropriate for a stunting only study, but future Link NCA’s focused on this form of undernutrition should continue to take into consideration new and emerging evidence on risk factors that specifically affect stunting.
