Ambulatory blood pressure monitoring (ABPM) is an important tool in the diagnosis and management of childhood hypertension. Normal ambulatory blood pressure (ABP) values in children with body heights between 100 and 120 cm have not been reported. The aim of the study was to establish the normal range of values for ABPM in these children. 24-hour ABPM was performed in 40 normotensive (auscultatory casual blood pressure was obtained before ABPM) subjects, aged from 4 to 6 years (26 males, 14 females) with body heights between 95 and 125 cm. ABPM was carried out on non-dominant arm using the oscillometric device (SpaceLab 90207) with appropriate cuff size. The monitor was programmed to measure BP every 15 min. during the day (6 a.m. to 10 p.m.) and every 30 min. during the night (10 p.m. to 6 a.m.). The mean daytime SBP/DBP in boys and girls was 108+/-6/67+/-5 and 105+/-5/66+/-1, respectively. The mean nighttime SBP/DBP in boys and girls was 98+/-6/56+/-5 and 97+/-7/56+/-4, respectively. There was a significant difference between day and night readings of SBP, DBP and heart rate (nocturnal fall was observed). The distribution of ABP noted in this study could serve as preliminary reference. A multicenter study should be performed to provide normal ranges of ABP.
