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
ABSTRACT
The amounts of iron and amino acids in dried pig powder were determined. It contained a large quantity of iron (230-260m/100g) and all essential amino acids. The blood fortified wheat flour biscuit containing 15mg Fe/100g was made and 30?2g of the biscuit was given to 65 primary school students (age 8-10) per capita per day during school day break for 40 days from Sep to Oct in 1984. For the control group, equal amount of the same biscuit without blood fortification was given to 34 subjects of the same age. Finger blood was taken for determination of hemoglobin, hematocrit, RBC count and serum ferritin before and after the experiment.there were significant differences (P
