Background

Blood pressure measurement (BPM) is a common procedure in clinical practice, but it can be challenging to obtain reliable values in children. Casual office BPM (gold standard) is all but accurate and ABPM may be difficult to perform or even misleading. Multiple Office Blood
Pressure Measurement (mOBPM) was developed at our Center in 2010 for evaluating BP with serial and automated measurements (≥10 in at least 30 min) using standard oscillometric devices. BP values were uploaded in a software and coefficient of variation (CV) was calculated after
excluding outlier values (<5th and & >95th centile of the recorded values).

Methods

The present study compares results obtained with mOBPM vs ABPM in children addressed to our Center for suspected arterial hypertension (AH). Given that children develop myocardial hypertrophy soon after the development of AH, Cardiac Mass Index (CMI) was used as gold
standard to categorize patients as hypertensive or normotensive.

Results

Twenty-five children were enrolled. AH was confirmed by increased CMI in 5 (20%) of them. ABPM identified 11 (44%) hypertensive children vs 12 (48%) identified by mOBPM. Sensitivity and specificity were 60% and 60% using ABPM vs 100% and 65% using mOBPM. PPV and PNV
were 27% and 86% vs 42% and 100%, respectively.

Conclusion

The present analysis shows that mOBPM is more reliable than ABPM in the diagnosis of AH in children. We recommend the routine use of mOBPM for measuring BP since ABPM may lead to wrongful diagnosis, can provide misleading results because of children discomfort and is more time-consuming.
