undernourishment

It notes that, in recent years, experts have come to the conclusion that undernourishment between conception and a child's second birthday can have serious and long-lasting impacts.

Ruel says in the 1980s Thailand was able to reduce child undernourishment by recruiting a large number of volunteers to travel the countryside teaching about health and nutrition.

Undernourishment during this approximately 1, 000-day window can seriously check the growth and development of children and render them more likely to get sick and die than well-fed children.
