Term infants, were examined at 9 (n=215) and 15 (n=198) months of age for levels of serum and red cell folate, hemoglobin, serum iron, total iron binding capacity, free erythrocyte protoporphyrin and serum ferritm. Mean erythrocyte folate levels were consistently higher (p < 0,005) in iron deficient anemic infants. No diferences were noted in serum folate levels. These results suggest, assuming similar intakes of folate, that folate stores depend on the sufficiency of iron nutrition. Iron deficient erythropoieses determines less utilization of folate stores.

School age children (n=84) of low socioeconomic status showed a prevalence of folate deficiency (Rbc folate
