Key result
Lean, prepubertal children with BP >12 mmHg above the 95th percentile warrant workup for renal causes.
Why the study?
Renal parenchymal and renovascular diseases are the leading causes of secondary HTN in children and warrant thorough investigation, particularly in lean, prepubertal children with stage 2 HTN.
Highlights the need to investigate secondary hypertension causes, specifically renal parenchymal and renovascular disease, in lean prepubertal children presenting with stage 2 hypertension.

May support targeted renal evaluation in this subgroup; leaves open prospective validation before practice change.
The incidence of pediatric hypertension (HTN) is on the rise alongside the obesity epidemic in developed countries due to the increased incidence of essential/primary HTN in children [1]. However, secondary HTN should be considered, particularly in lean, prepubertal children with blood pressure exceeding the 95th percentile for age by more than 12 mmHg (stage 2 HTN). Renal parenchymal disease and renovascular disease are the leading causes of secondary HTN [1] in children and warrant thorough investigation.

Huang et al. (2025) conducted a review in Suspected secondary hypertension in children. Diagnostic renal arteriography was evaluated. Secondary hypertension in lean, prepubertal children with blood pressure >12 mmHg above the 95th percentile warrants investigation for renal parenchymal and renovascular disease.
