背景虽然高血压的诊断应基于多次测量血压（BP），特别是考虑到首次读数时血压的短暂升高，人群中高血压的患病率通常依赖于单次就诊的测量。目的确定一种有效的策略，用于可靠地评估人群中高血压的患病率，设计基于人口的BP调查和后续信息设置和参与者达累斯萨拉姆地区25-64岁的所有居民主要结果测量在所有高血压参与者（n = 653）和662名没有高血压的参与者中连续四次访问的三个血压读数，结果4次访视中，血压从第1次到第3次均明显下降。血压在前两次访视之间大幅下降，但在下一次访视之间仅略有下降。因此，基于第三次阅读的高血压患病率-或第二次和第三次读数的平均值-在第二次访视时与基于第四次访视时读数的估计值相比没有很大差异。BP下降类似时，前三次访问分开3天或14天intervation.Conclusions采取三重读数两次访问，可能分开几天，可能是一个最小的策略，充分评估平均血压和高血压的患病率在人口水平。合理的策略对于可靠地评估人群中的高血压负担非常重要。(C)2003年利平科特威廉姆斯威尔金斯。
Background Although it is well recognized that the diagnosis of hypertension should be based on blood pressure (BP) measurements taken on several occasions, notably to account for a transient elevation of BP on the first readings, the prevalence of hypertension in populations has often relied on measurements at a single visit.Objective To identify an efficient strategy for assessing reliably the prevalence of hypertension in the population with regards to the number of BP readings required.Design Population-based survey of BP and follow-up information.Setting and participants All residents aged 25-64 years in an area of Dar es Salaam (Tanzania).Main outcome measures Three BP readings at four successive visits in all participants with high BP (n = 653) and in 662 participants without high BP, measured with an automated BP device.Results BP decreased substantially from the first to third readings at each of the four visits. BP decreased substantially between the first two visits but only a little between the next visits. Consequently, the prevalence of high BP based on the third reading - or the average of the second and third readings - at the second visit was not largely different compared to estimates based on readings at the fourth visit. BP decreased similarly when the first three visits were separated by 3-day or 14-day intervals.Conclusions 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. (C) 2003 Lippincott Williams Wilkins.
