Diagnosing Hypertension in Children and Adolescents

摘要

Dr Hansen and colleagues1 compared blood pressure measured in children and adolescents with age-adjusted and height-adjusted 95di percentiles. Following current guidelines,2 they categorized participants as having hypertension if either die systolic blood pressure or the diastolic blood pressure exceeded the corresponding 95th percen-tile on 3 occasions. The blood pressure of each participant was determined at least 3 times. The mean number of blood pressure determinations per participant was 3.8. The study spanned a period of 7 years 3 months, so it is possible that the blood pressure of some participants was measured many times, but the maximum number of times a participant was observed was not reported#
