Table 5 Scheme for the classification of systolic and diastolic blood pressure values obtained by 24-h blood pressure monitoring in children

From: Novelty in hypertension in children and adolescents: focus on hypertension during the first year of life, use and interpretation of ambulatory blood pressure monitoring, role of physical activity in prevention and treatment, simple carbohydrates and uric acid as risk factors

Classification Office SBP/DBP a 24-h ambulatory SBP/DBP b SBP or DBP load (%) b
Normal blood pressure <90th percentile <95th percentile <25
White coat hypertension ≥95th percentile <95th percentile <25
Prehypertension ≥90th percentile <95th percentile ≥25
Masked hypertension <95th percentile >95th percentile ≥25
Hypertension >95th percentile >95th percentile 25–50
Severe hypertension >95th percentile >95th percentile >50
Dipping subjects: mean nocturnal values at least 10 % lower than diurnal values
