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

研究的领域是日本岩手县大崎村的Uchikawame区。1988年对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)每天测量两次家庭血压(HBP)(一次在醒来后不久，另一次在退休前不久)，持续4周；研究人群部分重叠。早晚两次测量的压力没有显著差异，性别之间也没有显著差异。无论男女，SBP和DBP都随着年龄的增长而增加。与偶发血压(CBP)相比，HBP(SBP和DBP)往往比CBP低5-10 mm Hg。对439名不同年龄(6~14岁)学龄儿童(男221名，女218名)进行了随意听诊法和自动测量血压的同步测量。结果表明，选择最合适的袖带(上臂绷带)对正确测量儿童的家庭血压至关重要。测量了460名受试者的24小时动态血压(AMBP)，家庭血压与个体AMBP的相关性较差，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.
