A Study on Sodium and Potassium Intakes and their Metabolisms of Preschool Children in Seoul Area


Abstract
The purpose of this study was to estimate the sodium and potassium intakes and their metabolisms of preschool children, and to evaluate the relationship between the blood pressure and the related variables.
The subjects consisted of ninety-five preschool children aged two to six years (male 57, female 38). Twenty-four hour urines of subjects were collected for the measurements of their volume, sodium, potassium, creatinine and urea nitrogen. At the same time, the questionnaire was designed to assess the sodium and potassium intakes.
The results obtained were as follows ;
1) The urinary excretion of sodium in 24 hours was 54.622.4mEq(or1255.8mg)and dietary sodium intake was 2147.0-t-518.4mg. The dietary sodium intake significantly increased with increasing age(p=0.0151). However, daily sodium intake per unit body surface area did not show significant difference by age.
2) The urinary excretion of potassium in 24 hours was 14.27.6 mEq (or 555.2 mg) and the potassium intake was 1133.8mg.
3) The urinary excretions of creatinine and urea nitrogen were 240.2--126.2mg and 2946.71693.9mg, respectively.
4) The principal food source of sodium intake was the seasoning group, which contributed 49.9% to total sodium intake.
5) The main food source of potassium intake was milk and milk products, from which 28.6% of total potassium intake was obtained.
6) The blood pressure showed highly positive correlations with height, weight and body surface area(p<0.001). In addition, the blood pressure was found to be correlated with urinary sodium excetion and dietary sodium intake (p<0.01).
