EFFECTS OF MILD IRON DEFICIENCY ANEMIA ON CHILDREN'S PHYSICAL WORK CAPACITY / 营养学报

ABSTRACT

This study was carried out to determine the effects of mild iron deficiency anemia (IDA) on physical work capacity (PWC) of 7-year-old children in Beijing. Ninety-three mild IDA children and thirty-seven well-to-do children served as volunteer subjects. Finger blood samples were obtained for Hb, FEP, FEP/Hb, SF determination; PWC data were assessed by measuring PWC 170, R.PWC170, Workload Heart Rates (W.HR), estimated Vo2max before, in the middle, and after treatment, respectively. After the mild IDA children were cured with iron supplement (300mg ferrous sulfate per day) for 60 days, their values of Hb, FEP, FEP/Hb, SF changed significantly from original 10.5g/dl, 41.8ng/dl, 4.6?g/g, 13.2ng/ml to 12.5g/dl, 24.1?g/dl, 2.0?g/g, 75.7ng/ml respectively (P
