El propósito de este trabajo es el de presentar un análisis comparativo de los resultados de seis investigaciones en las cuales ha participado el autor sobre la relación entre la deficiencia de hierro y el funcionamiento intelectual. Las investigaciones fueron realizadas en Egipto, Estados Unidos, Guatemala, Indonesia y Tailandia entre niños de edad pre-escolar. La deficiencia de hierro con anemia está entre las dos deficiencias nutricionales más prevalentes en el mundo y es de esperar que su prevalencia sea alta en el Perú, particularmente entre los infantes y niños y entre las madres gestantes y lactantes. Una de las causas importantes es el limitado consumo de alimentos ricos en hierro hemínico que generalmente son muy costosos para los grupos más pobres de la sociedad. El análisis comparativo muestra que los resultados son consistentes a través de los seis estudios y que la deficiencia de hierro con anemia afecta el rendimiento en las pruebas de procesos cognoscitivos específicos y en las pruebas de rendimiento escolar. Los resultados también muestran que dichos efectos son reversibles con el tratamiento apropiado. A su vez, el análisis muestra que no hay evidencia suficiente para inferir que la deficiencia de hierro sin anemia afecta el cociente intelectual. The purpose of this paper is to present a comparative analysis of the results of six researches in which the author has participated, about the relation between iron deficiency and intellectual performance. The researches were carried out in Egypt, U.S.A., Guatemala, Indonesia and Thailand, with pre-school and school children. Iron deficiency with anemia are among the two nutritional deficiencies of major prevalence in the word and it must be expected that the same goes for Peru. One of the causes of the low consuming of food rich in iron is that these are too expensive for groups of low socioeconomic level. The comparative analysis shows consistent results in the six studies and that iron deficiency affects achievement in cognitive processes tests and academic tests. Results also show that the effects are reversible when appropriate treatment is given. At the same time, the analysis shows that there is not enough evidence to infer that iron deficiency without anemia affects the intellectual quotient.
