ABSTRACT
PIP: Exclusively breastfed infants have been known to maintain a state of iron sufficiency until at least 6 months of age. Introduction of solid foods while breastfeeding has been associated with the development of iron deficiency in infants. This study evaluates the iron status of 7 Peruvian Quechua Indian infants who were exclusively breastfed for periods of 7.5-12 months of age. Capillary blood samples were collected and centrifuged. Nonhemolyzed samples were brought to the U.S. for determination of serum ferritin concentration and erythrocyte porphyrin. Serum ferritin was determined by radioimmunoassay while erythrocyte porphyrin values were measured using a fluorometric procedure in a front-faced fluorometer. 40 nonanemic U.S. infants aged 9-12 months who had been fed on a mixed diet served as a comparison group for serum ferritin values. All serum ferritin values of the 7 infants were in the normal range ( 10 ng/ml), and the mean value for the group was similar to that of their American counterparts. Although the population in this study is small, the subjects represent a larger number of exclusively breastfed infants for prolonged periods of time and for whom serum ferritin values are available. This study suggests that exclusive breastfeeding is sufficient to maintain adequate iron nutrition for most of the 1st year of life.
