Assessing the Relationship of Aflatoxin Exposure and Stunting in Children 6-59 Months of Age in 10 Districts of Nampula Province, Mozambique

Publication Type

The aim of this study was to enumerate the serum aflatoxin B1 (AFB1) in children 6-59 months of age, and estimate its association with linear growth in these children. To accomplish this aim, the team conducted a cross-sectional study that focused on understanding the extent and level of aflatoxin exposure as measured through presence in a serum sample from children. We also studied the association between serum aflatoxin and chronic malnutrition (stunting), accounting for other risk factors. The specific objectives of this study include: 1.

Markers of Environmental Enteric Dysfunction Are Associated with Poor Growth and Iron Status in Rural Ugandan Infants

Publication Type



Environmental enteric dysfunction (EED), characterized by altered intestinal permeability/inflammation, microbial translocation, and systemic inflammation (SI), may be a significant contributor to micronutrient deficiencies and poor growth in infants from low-resource settings.


We examined associations among EED, SI, growth, and iron status at 6 mo of age.
