Before revision: Background: Stunting-or impaired child growth due to undernutrition-has multiple negative health effects, making it a top global health priority. The current benchmark for classifying stunting assumes a universal model of growth with height-for-age z-score (HAZ) cutoffs set by the World Health Organization.
After revision: Objectives: Current standards for comparing stunting across human populations assume a universal model of growth with height-for-age z-score (HAZ) cutoffs set by the World Health Organization.
