Abstract:
The effect of iron deficiency on the attention span was studied in 169 school children between 6 to 11 years of age. All were studied by hematological procedures and psychological methods in order to know the nutritional status for iron and their capacity of attention. Then were treated with iron sulfate for 12 weeks, and the hematological and psychological studies were repeated. Results shown iron deficiency anemia in 17.1 percent of the children, and iron deficiency, without anemia, in 14.7 percent. After treatment of the school children the scores and time required in a visual attention test improved. Also there was a favorable change in the scores obtained by one the subtests of the WISC Test. Findings are discussed and it is mentioned that a program for combating iron deficiency anemia through food fortification most be implemented.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
