Table 2. Prevalence of Elevated and Hypertensive Blood Pressure^a Among US Children Aged 8 to 17 Years (N = 36,612,323)^b, by Biennial Cycle, National Health and Nutrition Examination Survey (NHANES) 2011–2018.

NHANES cycle	Elevated Blood Pressure Prevalence, % (95% CI)	Hypertensive Blood Pressure Prevalence %, (95% CI)
2011–2012	8.3 (6.4–10.7)	4.6 (3.5–6.1)
2013–2014	6.0 (4.6–8.0)	2.6 (1.7–3.8)
2015–2016	8.2 (6.6–10.3)	4.3 (2.9–6.3)
2017–2018	6.2 (4.2–9.3)	3.9 (2.9–5.3)

^a Hypertensive and elevated blood pressure determined by 2017 American Academy of Pediatrics guidelines. Hypertensive: blood pressure percentile ≥95 or average blood pressure ≥130/80 mm Hg (whichever was lower) for children aged 8–12 years and ≥130/80 mm Hg for children aged ≥ 13 years. Elevated blood pressure: ≥90th percentile to <95th percentile or 120/<80 mm Hg to <95th percentile (whichever is lower) for children aged 8–12 years and 120/<80 to 129/<80 mm  Hg for children aged 13 to 17 years.

^b Unweighted, N = 5,971.
