Hypertension occurs in around 0.2 to 3% of newborns; however, blood pressure is not measured routinely in healthy newborns.<ref name=Dionne>{{cite journal | vauthors = Dionne JM, Abitbol CL, Flynn JT | title = Hypertension in infancy: diagnosis, management and outcome | journal = Pediatric Nephrology | volume = 27 | issue = 1 | pages = 17–32 | date = January 2012 | pmid = 21258818 | doi = 10.1007/s00467-010-1755-z | s2cid = 10698052 }}</ref> Hypertension is more common in high risk newborns. A variety of factors, such as [[Gestational age (obstetrics)|gestational age]], postconceptional age, and [[birth weight]] need to be taken into account when deciding if blood pressure is normal in a newborn.<ref name=Dionne />

Hypertension defined as elevated blood pressure over several visits affects 1% to 5% of children and adolescents and is associated with long-term risks of ill-health.<ref name=fourth>{{cite journal | title = The fourth report on the diagnosis, evaluation, and treatment of high blood pressure in children and adolescents | journal = Pediatrics | volume = 114 | issue = 2 Suppl 4th Report | pages = 555–576 | date = August 2004 | pmid = 15286277 | doi = 10.1542/peds.114.2.S2.555 | author1 = National High Blood Pressure Education Program Working Group on High Blood Pressure in Children Adolescents | doi-broken-date = 2 December 2024 | hdl = 2027/uc1.c095473177 | hdl-access = free }}</ref> Blood pressure rises with age in childhood and, in children, hypertension is defined as an average systolic or diastolic blood pressure on three or more occasions equal or higher than the 95th percentile appropriate for the sex, age, and height of the child. High blood pressure must be confirmed on repeated visits however before characterizing a child as having hypertension.<ref name=fourth /> In adolescents, it has been proposed that hypertension is diagnosed and classified using the same criteria as in adults.<ref name=fourth />
