Aflatoxin and Stunting in Young Children

Shedding light on the association between aflatoxin and stunting in young children

The U.S. Centers for Disease Control estimates that over 4.5 billion people are chronically exposed to aflatoxin in their diet. The case for the association between aflatoxin exposure in children and stunting is still not clear. While the few studies that have looked at this association found surprisingly large effects, the results remain inconclusive. The objective of the project is to establish whether, and quantify to what extent, aflatoxin exposure leads to linear growth retardation in early childhood. The project will draw on existing household data and blood samples from recent studies in Uganda and Mexico. These data will be used to estimate the association between aflatoxin and child stunting, controlling for potentially confounding factors. The project will be carried out in collaboration with the Markets, Trade and Institutions division.
