| Abstract |
Purpose
: Recommended dietary allowance of vitamin C was determined on the basis
of preventing the scurvy without considerations of the important function of the vitamin C as a first line antioxidant. So we measured the whole blood and plasma vitamin C concentrations of the contemporay healthy elementary school children in Chinju for the establishment of the optimal daily vitamin C requirment in the elementary school children.
Methods
: Whole blood and plasma vitamin C concentrations were measured by the
2, 4-dinitrophenylhydrazine method in 338 children from the 1st to the 6th grade of one elementary school in Chinju.
Results
: Whole blood and plasma vitamin C concentrations were 1.36¡¾0.34mg/dL and
1.07¡¾0.33mg/dL respectively. There existed an close relationship between whole blood
and plasma vitamin C concentrations(r=0.77, p=0.0001). Whole blood vitamin C
concentration decreased as the age became older(r=-0.22 p=0.0001), but plasma vitamin
C concentration didnotchange. There were no sex differences in the whole blood and
plasma vitamin C concentrations except in the 3rd grade(p<0.05). Twenty-three of 338
elementary school children(6.8%) had the plasma vitamin C concentration less than
0.6mg/dL.
Conclusion
: We produced the blood and plasma vitamin C concentrations of the
contemporay elementary school children in Chinju. These values were not satisfactory in consideration of the importance of the childhood health. |
