Classification of blood pressure by ABPM in children and adolescents^*

• Normal BP: <90th percentile by ABPM

• Hypertension: ≥95th percentile by ABPM

• White coat hypertension: Casual BP ≥ 95th percentile in medical setting but casual BP or ABPM ≤ 95th percentile

• Masked prehypertension: Casual BP < 90th percentile in the medical setting but BP at 90–94th percentile by casual BP or by ABPM

• Masked hypertension: BP < 90th percentile by casual BP in medical setting but BP ≥ 95th percentile by casual BP or by ABPM

• Blood pressure load: 20%–50% systolic and/or diastolic BP by ABPM values above reference percentile¥

Notes:

^*ABPM reference limits;14

^¥no consensus on definition of hypertension based on blood pressure load.
