Abstract

The authors hypothesized that published hypertension rates inTanzania were influenced by the physiological response ofindividuals to blood pressure (BP) testing, known as thewhite-coat effect (WCE). To test this, a representative sample of 79 participants from a baseline cohort of 2322 people aged 70years and older were followed to assess BP using conventional BP measurement (CBPM) and ambulatory BP monitoring (ABPM). There was a significant difference between daytime ABPM and CBPM for both systolic BP (mean difference 29.7mmHg) and diastolic BP (mean difference 7.4mmHg). Rates of hypertension were significantly lower when measured by 24-hour ABPM (55.7%) than by CBPM (78.4%). The WCE was observed in 54 participants (68.4%). The WCE was responsible for an increase in recorded BP. Accurate identification of individuals in need of antihypertensive medication is important if resources are to be used efficiently, especially in resource-poor settings.
