Feasibility study on home blood pressure measurement and 24-hr blood pressure monitoring in public health

研究地点为日本岩手县大崎村内川区。1988年和1989年分别对1190名成年人（495名男性和695名女性）和718名成年人（309名男性和409名女性）进行了为期4周的家庭血压（HBP）测量，每天两次（一次是在起床后不久，另一次是在退休睡觉前不久）；研究人群部分重叠。在早上和晚上的测量中没有观察到明显的压力差异，两性之间也没有。收缩压和舒张压均随着年龄的增长而增加。与随意血压（CBP）相比，HBP（收缩压和舒张压）往往比CBP低5-10毫米汞柱。通过对439名不同年龄（6-14岁）的小学生（男221名，女218名）进行随机听诊法和自动血压测量（使用一种原本用于家庭血压测量的仪器）同时测量血压的研究表明，选择最合适的袖带（上臂周围的绷带）对于正确测量儿童家庭血压至关重要。测量460名受试者24小时动态血压（AMBP）；家庭血压与个体AMBP相关性较差，相关系数为0.6。

The field studied was Uchikawame district of Ohazama village in Iwate Prefecture, Japan. Home blood pressure (HBP) was measured twice a day (once soon after wake-up and the other shortly before retirement to bed) for 4 weeks in 1190 adults (495 men and 695 women) in 1988, and 718 adults (309 men and 409 women) in 1989; the study populations were partially overlapped. No significant difference in pressure was observed between the morning and evening measures, nor between the two sexes. Both SBP and DBP tended to increase as a function of progress in age in either sex. When compared with casual blood pressure (CBP), HBP (both SBP and DBP) tended to be lower than CBP by 5-10 mmHg. Simultaneous measurement of blood pressure with casual auscultation method and automated measurement (with an instrument originally for home blood pressure measurement) among 439 school children (221 boys and 218 girls) of various ages (6-14 years) showed that the selection of the best fit cuff (the bandage around the upper arm) is of critical importance for the correct measurement of home blood pressure of children. Twenty four-hr ambulatory blood pressure (AMBP) was measured in 460 subjects; the correlation of home blood pressure with AMBP on individual basis was rather poor with a correlation coefficient of 0.6.
