The importance of high blood pressure (BP) as a modifiable risk factor for early disability and death is well established [1]. Although the majority of adverse outcomes occur in adulthood, high BP is a lifelong problem that can become apparent early in life, its importance in the young being recognized by the recommendation of guidelines [2–7] to start measuring BP at the age of three years and at any available occasion thereafter. Childhood hypertension (HTN) is not uncommon, 2–4 % and increasing over decades [8], but its actual prevalence varies in different studies due to normative data used and demographic changes over time.
