title: Twenty-four hour blood pressure monitoring in healthy children.
abstract: Blood pressure and heart rate were measured every 20 min during the day and every 30 min during the night in 105 children (51 girls and 54 boys, aged 6-10 years) with a portable automated blood pressure monitor using an oscillometric principle of measurement. The monitor was well accepted by most of the children and the rate of invalid measurements was only 13%. Mean systolic and diastolic blood pressure was 114 +/- 7/72 +/- 5 by day and 99 +/- 7/56 +/- 6 by night. The corresponding heart rates were 93 +/- 8 and 72 +/- 9 beats/min. No significant differences were found between boys and girls. At night, systolic blood pressure dropped by 13% +/- 4%, the diastolic value by 22% +/- 7% and heart rate fell by 22% +/- 6%. Mean systolic and diastolic blood pressure measurements correlated positively with the subject's height, whereas no correlation was found with age.
