To define the range and variability of ambulatory blood pressure in normal schoolchildren.
Prospective study.
Resting blood pressure of 1121 schoolchildren from Newcastle upon Tyne was recorded. An ambulatory blood pressure device, which uses both auscultatory (Korotkoff) and oscillometric methods of blood pressure measurement, was then put in place for 24 hours.
The day was divided into three time periods: school, home, and night time. Normal centiles for blood pressure for each of these time periods were obtained and many daytime readings were outside reported normal resting levels. The normal variation of blood pressure was quantified by comparing each of these time periods with the resting readings. Resting systolic blood pressure did not predict 24 hour mean systolic blood pressure.
The availability of normal ambulatory blood pressure data on the level and variation of blood pressure in children may facilitate the early identification of hypertension in this age group.
确定正常学童动态血压的范围和变异性。
前瞻性研究。
记录了来自泰恩河畔纽卡斯尔的1121名学童的静息血压。然后使用一种结合听诊（柯氏音）和示波法测量血压的动态血压监测设备，持续监测24小时。
一天分为三个时间段：上学、在家和夜间。得出了每个时间段血压的正常百分位数，许多日间读数超出了报告的正常静息水平。通过将这些时间段中的每一个与静息读数进行比较，对血压的正常变异进行了量化。静息收缩压不能预测24小时平均收缩压。
关于儿童血压水平和变异的正常动态血压数据的可用性，可能有助于早期识别该年龄组的高血压。
