In order to determine reference values for the ambulatory blood pressure, a population sample of 328 subjects, aged 20-81 years, who reported themselves to be in good health, was investigated. The ambulatory blood pressure was recorded over 24 h, taking measurements at 20 min intervals from 8 am to 10 pm, and at 45 min intervals from 10 pm to 8 am. Blood pressure was also measured by trained observers on each of two separate home visits (5 readings per visit). The ambulatory blood pressure in the 328 subjects averaged 118/71 mmHg over 24 h, 124/76 mmHg during the day (10 am-8 pm), and 108/62 mmHg at night (0 am-6 am). Blood pressure measured by an observer at the occasion of the second home visit was 4/5 mmHg lower (P less than 0.001) than the daytime ambulatory blood pressure. The 95th centiles for the daytime ambulatory pressures were 144/95 mmHg in 85 men below age 50; 154/90 mmHg in 74 men aged greater than or equal to 50 years; 132/85 mmHg in 96 women below age 50; and 151/91 mmHg in 73 women aged greater than or equal to 50 years. The 95th centiles for the nighttime pressures in these four sex-age groups were 124/79, 140/83, 121/70, and 132/72 mmHg, respectively.
为了确定动态血压的参考值，对328名年龄在20 - 81岁、自称健康状况良好的受试者进行了群体抽样调查。动态血压记录24小时，从上午8点至晚上10点每20分钟测量一次，从晚上10点至上午8点每45分钟测量一次。血压还由经过培训的观察者在两次单独的家访中每次测量（每次家访测量5次）。328名受试者的动态血压24小时平均为118/71 mmHg，白天（上午10点至晚上8点）为124/76 mmHg，夜间（凌晨0点至上午6点）为108/62 mmHg。观察者在第二次家访时测量的血压比白天动态血压低4/5 mmHg（P小于0.001）。50岁以下85名男性白天动态血压的第95百分位数为144/95 mmHg；50岁及以上74名男性为154/90 mmHg；50岁以下96名女性为132/85 mmHg；50岁及以上73名女性为151/91 mmHg。这四个性别 - 年龄组夜间血压的第95百分位数分别为124/79、140/83、121/70和132/72 mmHg。
