A blood pressure measurement was part of a cardiovascular screening examination of 8397 middle-aged men taking part in the intervention section of the United Kingdom Heart Disease Prevention Project. Standardised training techniques reduced observer bias to acceptable limits in four out of a total of five observers. The time of day and room temperature both made significant differences to the blood pressure measurement. High room temperatures in particular apparently had a marked effect in reducing the level of blood pressure. There were consistent and large positive associations with increasing age and overweight. The survey revealed a poor degree of blood pressure control in the community at the time of screening--only 7% of the "hypertensive" population had their diastolic pressure controlled to below 100 mm Hg.
血压测量是对参与英国心脏病预防项目干预部分的8397名中年男性进行心血管筛查检查的一部分。标准化培训技术将五名观察者中的四名观察者偏差降低到了可接受的限度。一天中的时间和室温对血压测量均有显著影响。特别是高室温显然对降低血压水平有显著作用。年龄增长和超重之间存在持续且显著的正相关。调查显示,在筛查时社区中的血压控制情况较差——只有7%的“高血压”人群舒张压控制在100毫米汞柱以下。
