Few reports provide clear guidelines on how home blood pressure (HBP) should be measured in practice. In this study, we evaluated the influence of repeated HBP measurements on one occasion, and the difference between the 1st and 2nd day and between workdays and nonworkdays. The subjects (468 male, 232 female; mean age 41 years) were recruited from one company. HBP was measured with a semiautomatic device (Omron HEM-759P). Subjects were instructed to perform triplicate morning (m) and evening (e) measurements on 7 consecutive days. HBP tended to decrease during repeated measurements: systolic blood pressure (SBP) was significantly higher the 1st time than the 2nd time and 3rd time. There was no difference in diastolic blood pressure (DBP) between the 1st and 2nd time, but the value the 3rd time was significantly lower than the 1st and 2nd time. Both mHBP and eHBP on the 1st day were significantly higher than those on the 2nd day. mHBP was higher on the 1st workday than on nonworkdays, but the difference was less than 1 mmHg and there was no significant difference. Since there were significant differences in HBP during repeated measurements and between the 1st and 2nd day, which value to adopt as HBP needs to be discussed. Whether HBP was measured on a workday or a nonworkday seemed to have little influence on the HBP values obtained.
很少有报告就实际中应如何测量家庭血压（HBP）提供明确的指导方针。在本研究中，我们评估了一次重复测量HBP的影响，以及第一天与第二天之间以及工作日与非工作日之间的差异。研究对象（468名男性，232名女性；平均年龄41岁）来自一家公司。使用半自动设备（欧姆龙HEM - 759P）测量HBP。受试者被要求连续7天每天早晚各测量三次。重复测量期间HBP有下降趋势：收缩压（SBP）第一次测量时显著高于第二次和第三次。舒张压（DBP）第一次和第二次测量时无差异，但第三次测量值显著低于第一次和第二次。第一天的早晨HBP（mHBP）和晚上HBP（eHBP）均显著高于第二天。第一个工作日的mHBP高于非工作日，但差异小于l mmHg，无显著差异。由于重复测量期间以及第一天和第二天之间HBP存在显著差异，因此需要讨论采用哪个值作为HBP。在工作日还是非工作日测量HBP似乎对所获得的HBP值影响不大。
