Blood pressure definitions, as defined by the 2017 Clinical Practice Guidelines (15).

BP category	Children aged 1–13 years*	Children aged ≥13 years
Normal BP	<90th percentile†	<120/<80 mmHg
Elevated BP	≥90th to <95th percentile	120/<80 to 129/<80 mmHg
Stage 1 HTN	≥95th to <95th percentile + 12 mmHg	130/80 to 139/89 mmHg
Stage 2 HTN	≥95th percentile + 12 mmHg	≥140/90 mmHg

^*If blood pressure values exceed criteria used for children aged ≥13 then those corresponding cutoffs are used.

^†All percentiles are age-, sex-, and height-matched. Of note, the Clinical Practice Guidelines included new reference tables derived from only lean subjects.
