This study described the seated blood pressure distribution of 681 primary school children (6 to 13 years) in Audi village, Taipei County. The systolic and diastolic blood pressure increased with age. There was no significant different both in systolic and diastolic blood pressure between boys and girls. with the first measurements, 95th percentile value curves were defined. Subjects with seated pressures greater than the 95th percentile for shecific age and sex were examined on repeated occasion. 30 subjects found to have persisted elevated blood pressure were defined as hypertension group. One to one matched by sex, age, height and body weight were control group. The mean urinary sodium and potassium excretion of early morning first spot urine did not differ significantly between two groups. The Na/K-ratio showed no difference between two groups. Multiple regression analysis between blood pressure and seven independent variables-sex, age, height, weight, urinary Na, K, Na/K-ratio showed correlation (R=0.41 for systolic, R=0.51 for diastolic, p<0.0l). Stepwised analysis showed body weight was the most important determinant (R=0.37 for systolic. R=0.48 for diastolic).
