Childhood blood pressure trends and risk factors for high blood pressure: the NHANES experience 1988-2008.

ABSTRACT: The obesity epidemic in children makes it plausible that prevalence rates of elevated blood pressure (BP) are increasing over time. Yet, previous literature is inconsistent because of small sample sizes. Also, it is unclear whether adjusting for risk factors can explain longitudinal trends in prevalence of elevated BP. Thus, we analyzed a population-based sample of 3248 children in National Health and Nutrition Examination Survey (NHANES) III (1988-1994) and 8388 children in continuous NHANES (1999-2008), aged 8 to 17 years. Our main outcome measure was elevated BP (systolic BP or diastolic BP ≥ 90th percentile or systolic BP/diastolic BP ≥ 120/80 mm Hg). We found that the prevalence of elevated BP increased from NHANES III to NHANES 1999-2008 (Boys: 15.8% to 19.2%, P=0.057; Girls: 8.2% to
