ABP is more reliable and reproducible than casual BP, enables computation of the mean, daytime, night-time ABP, and 24-h pulse pressure, detects white coat effect or reversed white coat effect, and provides information regarding diurnal BP pattern as well as BP variability. ABP correlates better with target-organ damage than casual BP. ABPM is now widely used also in children. Increasing age and higher mean BP are factors that improve the success rate of ABPM. There is a guideline from American Heart Association to standardize the use of ABPM in children, including the detailed recommendations for the use of ABPM and for the interpretation of the data. Studies from several countries reported normal values for ABP in children by age and gender. Normal ABP values by height are also available.ABPM is useful when confirming the diagnosis, assessing the target organ damage, and treating and evaluating the effectiveness. While the advantages of ABP are shared by home BP to some extent, nocturnal BP, 24-hour pulse pressure, and short term BP variability can be measured only by ABPM. ABPM in the initial evaluation of suspected childhood HTN was shown to be highly cost-effective.
