CB1-01: Prevalence of HT in Children: Comparison Between Task Force Recommendations and Average of Multiple Measurements Over 2 or 4 Years

Background/Aims Identification of persistently elevated blood pressure (BP) in children can be challenging because BP measurements are subject to biological fluctuation and measurement error. The National High Blood Pressure Education Program 4th Working Group (NHBPEP) Guidelines define hypertension (HT) as BP that is =95th percentile for sex, age and height on 3 consecutive clinic measurements on different days. However, HT is a chronic condition, and it is not clear whether a definition incorporating multiple measures over a longer period of time would alter the prevalence compared to the present definition of HT.
