Stunting, Selenium Deficiency and Anemia are Associated with Poor Cognitive Performance in Preschool Children from Rural Ethiopia

Researchers examined how anthropometry, iron biomarkers, and serum selenium are linked to cognitive performance in preschool-aged children in rural Ethiopia. Two cognitive tests revealed that children who were stunted, anemic, or selenium deficient did not perform as well as their peers. The relationship between cognitive deficits, micronutrient deficiency, and chronic undernutrition suggest a need for more effective intervention programs.
