Hypertensive Conditions: Hypertension in Children and Adolescents.

Hypertension (HTN) in children and adolescents is a spectrum of disease, ranging from elevated blood pressure (BP) to stage 1 and 2 HTN. The prevalence of elevated BP and HTN in this age group has increased significantly over the past 20 years, particularly in girls. Screening for HTN in asymptomatic children and adolescents is controversial. Primary HTN is now the predominant cause of HTN among the pediatric population in the United States, especially among adolescents. Secondary pediatric HTN is high BP due to an underlying medical condition and is more common among children 6 years and younger. Ambulatory BP monitoring should be considered in pediatric patients with repeatedly elevated office BP measurements. All children with BP greater than the 90th percentile should be encouraged to adopt lifestyle changes, but those with persistent or severe elevations in BP may benefit from pharmacotherapy.
