Iron nutritional status of preschool children.

Abstract

Low hemoglobin and low MCHC levels were indicative of high incidence of iron deficiency in preschool children. The extent of iron deficiency as assessed by serum ferritin and free erythrocyte protoporphyrin showed a different trend. While FEP levels were highly suggestive of extensive iron deficiency (in 40-45% of children below the age of 5 years), low serum ferritin was seen in only 16-20% of children. The discrepant finding of high serum ferritin, and high erythrocyte protoporphyrin despite low MCHC in the present study, possibly reflects iron deficiency status along with chronic infection resulting in hyperferritinemia and hyperprotoporphyrinemia. It may be also due to associated folate deficiency resulting in non utilization of iron leading to the elevated levels of protoporphyrin.
