Relevance

Stunting, or chronic malnutrition, is the outcome of growth faltering that takes place in utero and early childhood as a result of inadequate nutrient intake and repeated bouts of infection. Stunting is largely irreversible, and in addition to suboptimal growth outcomes, it is associated with poor cognitive development, reduced productive capacity, and poor health. Stunting may also increase risk of overweight, obesity, and noncommunicable diseases later in life.
