In this study, hemoglobin (Hb), mean corpuscular volume (MCV) and serum ferritin (SF) levels were measured in 76 neonates and their mothers at delivery. Infants were grouped according to their gestational ages. Group I (< 34 weeks), group II (34-37 weeks) and group III (> 37 weeks) consisted of 15, 33 and 28 infants, respectively. Blood studies were repeated at two months of age in 50 neonates (26 from group II and 24 from group III). Among the three groups of infants, SF levels were lowest in group I, and among mothers, Group III had the lowest levels.
