公众对血压（BP）在心脏病和中风中的作用的理解知之甚少。本研究旨在更广泛地了解所选伦敦人群对BP的知识和认识。作为中风宣传活动的一部分，公众接受了BP测试，并被问及他们对BP的了解和认识。采用描述性统计来探讨BP的知识和意识。采用χ2检验探讨血压知识和知晓率的差异，以及血压正常者和高血压者的血压读数是否存在差异。共招募了1019名参与者（男性295名;平均年龄54岁，范围16-92岁），平均血压为130/77 mm Hg。超过一半（52%）的总人口无法正确估计血压的可接受范围，其中28%的收缩压（SBP）>140 mm Hg。在31%的自我报告的高血压和药物治疗中，超过四分之一（27%）的人不知道可接受的血压范围。三分之一的患者血压控制不佳，SBP >140 mm Hg。正确估计“可接受血压”的高血压参与者的平均SBP（147 mmHg）比错误估计的参与者（150 mmHg）低3 mmHg（P<0.04）。一般公众对BP仍缺乏了解，个人对可接受的BP范围知之甚少。高血压患者表现出对BP的理解特别差。这项研究表明，良好的知识BP影响血压控制在高血压人群中，并具有重要的公共卫生意义。
Little is known about the general public’s understanding of the role of blood pressure (BP) in contributing to heart disease and stroke. This study aimed to gain a wider understanding of the knowledge and awareness of BP in a selected London population. As part of a stroke awareness campaign, members of the public were offered BP testing and were asked about their knowledge and awareness of BP. Descriptive statistics were employed to explore knowledge and awareness of BP. χ2-test was run to explore the difference between knowledge and awareness of BP, and whether there was a difference in BP readings in normotensive and hypertensive participants. A total of 1019 participants (males 295; mean age 54 years, range 16–92) were recruited with a mean BP of 130/77 mm Hg. Over half (52%) of the total population was unable to correctly estimate an acceptable range of BP, and of that group 28% had a systolic BP (SBP) >140 mm Hg. Of the 31% self-reporting hypertension and on medication, over a quarter (27%) did not know the range for acceptable BP. A third were poorly controlled with a SBP >140 mm Hg. Mean SBP in the hypertensive participants who correctly estimated ‘acceptable BP’ was 3 mm Hg lower (147 mm Hg) than those who guessed incorrectly (150 mm Hg) (P<0.04). There remains a lack of understanding of BP in the general public population with individuals having little knowledge of an acceptable BP range. Hypertensive patients demonstrate a particularly poor understanding of BP. This study suggests that good knowledge of BP influences BP control in a hypertensive population and has important public health implications.
