Does taking triplicate blood pressure readings on two visits adequately assess mean blood pressure and hypertension prevalence at the population level?
Taking triplicate blood pressure readings on two visits is proposed as a minimal strategy for adequately assessing the prevalence of hypertension at the population level.
Taking triplicate readings on two visits, possibly separated by just a few days, could be a minimal strategy for assessing adequately the mean BP and the prevalence of hypertension at the population level. A sound strategy is important for assessing reliably the burden of hypertension in populations.
