摘要

The iron status of 206 infants and young children is South Taiwan were evaluated by measurements of serum iron, total iron binding capacity, serum ferritin, and hematological parameters of peripheral blood including hemo-globin (Hb), hematocrit, mean corpuscular hemoglobin (MCH), and mean corpuscular volume (MCV). 18 subjects aged 2 months were included in the study and no iron deficiency was found in this group. Four groups of the other subjects aged between 3 and 36 months were studied; A: 3-6 months, 28 subjects, B: 6-12 months, 29 subjects, C: 12-24 months, 91 subjects, D: 24-36 months, 40 subjects. Prevalence of iron deficiency in the those be-tween 3 and 36 months was 34%, including iron deficiency without anemia 22.9% (n=43) and iron deficiency anemia 11.1%(n=21). Most cases (96.9%) of iron deficiency occurred in the infants and children aged 6-36 months. Iron deficiency without anemia in the A, B, C and D groups was 3.6%, 17.2%, 25.3%, 35.0% respectively and iron deficiency anemia were 3.6%, 17.2%, 12.1%, 10.0% respectively. Hematoogical parameters are less valuable in diagnosis of iron deficiency, with accuracy of 68.8%, 63.8%, 68.8%, 64.3% respectively for these four groups. These parameters decline signifi-cantly in the iron deficiency anemia group, but not in the iron deficiency without anemia group. Low levels (Hb ＜ 11g/dl, hematocrit ＜ 33%, MCH ＜ 24pg, MCV ＜ 72 fl) are indicators of a need to search a cause of anemia, especially iron deficiency anemia in infants and children with ages between 3 and 36 months, but normal values do not exclude iron deficiency. Serum ferritin has the best sensitivity and specificity in diagnosis of iron deficiency in infancy and childhood, but normal values still do not exclude it. The cause of iron deficiency is mostly (70%) due to an inadequate supply of iron. Iron deficiency still remains a main problem of infancy and early child-hood in South Taiwan.
