Iron deficiency anemia: adverse effects on infant psychomotor development.
In a double-blind , placebo-control prospect i ve cohort study of 196 infants from birth to 15 months of age , assessment was made at 12 months of age of the relationship between iron status and psychomotor development , the effect of a short-term ( 10-day ) trial of oral iron vs placebo , and the effect of long-term ( 3 months ) oral iron therapy . Development was assessed with the mental and psychomotor indices and the infant behavior record of the Bayley Scales of Infant Development in 39 anemic , 30 control , and 127 nonanemic iron-deficient children . Anemic infants had significantly lower Mental and Psychomotor Developmental Index scores than control infants or nonanemic iron-deficient infants ( one-way analysis of variance , P less than .0001 ) . Control infants and nonanemic iron-deficient infants performed comparably . No difference was noted between the effect of oral administration of iron or placebo after 10 days or after 3 months of iron therapy . Among anemic infants a hemoglobin concentration less than 10.5 g/dL and duration of anemia of greater than 3 months were correlated with significantly lower motor and mental scores ( P less than .05 ) . Anemic infants failed specifically in language capabilities and body balance-coordination skills when compared with controls . These results , in a design in which intervening variables were closely controlled , suggest that when iron deficiency progresses to anemia , but not before , adverse influences in the performance of developmental tests appear and persist for at least 3 months despite correction of anemia with iron therapy . If these impairments prove to be long st and ing , prevention of iron deficiency anemia in early infancy becomes the only way to avoid them
