Background: Out of office blood pressure has been shown to be a better representation of an individual’s blood pressure. This prospective school-based study was designed to investigate the normal range of out of office blood pressure and its associated factors in adolescents.
Methods: A total of 718 adolescents (309 males and 409 females) were recruited and their blood pressures taken 6 times over 2 days. The prevalence of hypertension and the relationship between blood pressure level and height, body mass index, age and socio-economic status were determined. Results: The mean systolic blood pressures for males and females were 109.5 ± 13.9, and 112.2 ± 13.0 mmHg, respectively [p=0.01], while the mean diastolic pressures were 71.4 ± 9.2 and 74.19 ± 9.6 mmHg for the males and females, respectively [p
