Efecto de la anemia ferropriva en el lactante sobre el desarrollo psicológico del escolar

Abstract

Iron deficiency anemia is the most prevalent nutritional disorder in the world. Its effects are associated with delayed psychomotor development and behavior changes on whose long term persistence there still remains uncertainty. Two studies in children aged 5 years have shown continuing lower performances in those with former anemia. To evaluate the long term effects at age 10 years in the same cohort previously examined at age 5 years, we evaluated 64 children, 34 with former anemia and 30 without it. A complete psychological assessment didn't show the differences observed at 5 years in intellectual (IQ) ond total motor proficiency, but significant differences were observed in favour of those without antecedent of anemia in reaction time, scholastic achievement abilities (written language and specific skills), scholar achievement (physical education one mean general school grades), and in the scholar behavior. These results suggest that the association between anemia in infancy and negative effects on development continues at 10 years of age, shown mainly at specific behaviours required in the school context.
