[Comment] Childhood hypertension: a growing global concern in need of harmonised solutions

Globally, it is recognised that cardiovascular risk begins early in life, yet the epidemiology of childhood hypertension remains fragmented and contested. In The Lancet Child & Adolescent Health, Jiali Zhou and colleagues1 present an updated meta-analysis of the previous publication2 in 2019. In contrast to the previous meta-analysis, the authors provide estimates of hypertension, integrating both repeated in-office blood pressure measurements and combined in-office and out-of-office assessments, providing additional estimates of sustained, white-coat, and masked hypertension.
