 Suggested Revised Schema for Staging of Ambulatory BP Levels in Children

Classification	Office BP, Percentilea	Mean Ambulatory SBP or DBP, Percentileb,c	SBP or DBP Load, %c
Normal BP	<95th	<95th	<25
White‐coat HTN	>95th	<95th	<25
Masked HTN	<95th	>95th	>25
Pre‐HTN	≥90th and <95th	<95th	25–50
Ambulatory HTN	>95th	>95th	25–50
Severe ambulatory HTN (at risk for end‐organ damage)	>95th	>95th	>50

Abbreviations: DBP, diastolic blood pressure; HTN, hypertension; SBP, systolic blood pressure. ^aBased on the National High Blood Pressure Education Program Task Force Standards. ^{12 b}Based on ambulatory blood pressure (BP) monitoring values of Soergel and colleagues¹¹⁶ or the smoothed values of Wuhl. ^{123 c}For either the wake or sleep period of the study or both.
