| Abstract |
Purpose
: The Large amounts of whole cow’s milk intake, just followed by prolonged breast milk
feeding may induce a severe deficit of iron. We performed this study to investigate the severity of
iron deficiency in these subjects.
Methods
: Seventy-one subjects(12 to 48 months of age) were classified according to history of
prolonged breast milk feeding and intake of large amounts of whole cow’s milk. Prolonged breast
milk feeding and large amounts cow’s milk intake subjects were assigned as group A(n=15), the
large amounts of cow' s milk intake subjects as group B(n=15), the prolonged breast milk feeding
subjects as group C(n=24) and the normal control subjects as Group D(n=17). The hematologic and
iron status were evaluated and compared between each group.
Results
: Although the mean of group A was lower than the mean of group B and C, the level
of hemoglobin of group A was significantly lower than group D(P < 0.01). The level of the ferritin
of group A was significantly lower than group B, C(P < 0.05, respectively) and group
D(P < 0.01). Of the 15 study subjects of group A, 14(93.3%) had microcytic hypochromic anemia
and 7(46.7%) revealed that serum ferritin levels were at 1.0ng/dL, indicating severe deficit of
storage iron.
Conclusion
: The intake of large amounts of whole cow’s milk, just followed by prolonged breast
milk feeding induced iron deficiency anemia and a severe deficit of storage iron. It is necessary to
inform parents to avoid irreversible recognition impairment and behavioral change. |
