目的：评估在家测量的未治疗受试者的血压分布、参考值和日常变化。设计：队列横断面研究。背景：日本北部的一般社区。受试者：测量了 871 名受试者的血压（平均+/-标准差年龄 46.0+/-19.5 岁，范围 7-98，占内川当地人口的 38.7%） 方法：受试者每天早上使用半自动示波血压测量装置在家中至少测量自己的血压三次（平均值+/-SD 19.7+/-8.4）。筛查血压测量一次。主要结果指标：确定了整个研究人群的家庭血压分布以及年龄和性别的分布，以及家庭血压每日变化的分布。结果：平均家庭血压为117.3+/-13.4/69.3+/-9.7mmHg（95%置信区间116.4-118.2/68.7-70.0）。第 95 个百分位数值为 143/85 mmHg，平均值+SD 131/79 mmHg，平均值+2SD 144/89 mmHg。平均筛查血压为 126.2+/-18.9/72.1/-11.7 mmHg（95th 百分位数 159/92 mmHg）。获得了年龄和性别特异性的 95% 值以及平均值+/-SD。通过筛查血压确定为血压正常的受试者 (n = 707)，作为家庭血压参考上限获得的平均值+SD、平均值+2SD 和第 95 个百分位数值分别为 125/77、137/86 和 134/83 mmHg。男性和女性的家庭血压随着年龄的增长而逐渐升高，但男性的血压在 50 岁之前显着较高。家庭收缩压的日常变化也随着年龄的增长而增加。结论：由于家庭血压值的分布受年龄和性别的影响，因此应建立年龄和性别匹配的家庭血压参考值。应仔细评估老年受试者的家庭血压值，因为这些值表现出更大的日常变化。
Objective: To evaluate the distribution, reference values and day-to-day variation of blood pressure of untreated subjects measured at home.Design: Cross-sectional study of a cohort.Setting: General community in northern Japan.Subjects: Blood pressure was measured in 871 subjects (mean+/-SD age 46.0+/-19.5 years, range 7-98, constituting 38.7% of the local population of Uchikawama region, Ohasama) who were not receiving antihypertensive medication.Methods: Subjects measured their own blood pressure at home at least th ree times (mean+/-SD 19.7+/-8.4) each morning using a semi-automatic oscillometric blood pressure measuring device. Screening blood pressure was measured once.Main outcome measures: Distribution of home blood pressure in the study population as a whole and with respect to age and sex, and the distribution of day-to-day variation of home blood pressure were determined.Results: Mean home blood pressure was 117.3+/-13.4/69.3+/-9.7mmHg (95% confidence interval 116.4-118.2/68.7-70.0). The 95th centile value was 143/85 mmHg, mean+SD 131/79 mmHg and mean+2SD 144/89 mmHg. Mean screening blood pressure was 126.2+/-18.9/72.1/-11.7 mmHg (95th centile 159/92 mmHg). Age- and sex-specific 95th centile values as well as mean+/-SD were obtained. Mean+SD, mean+2SD and the 95th centile values obtained as reference upper limits of home blood pressure from subjects identified as normotensive by screening blood pressure (n = 707) were 125/77, 137/86 and 134/83 mmHg, respectively. Home blood pressure increased gradually with increasing age in both men and women, although blood pressure was significantly higher in men until 50 years of age. Day-to-day variation of home systolic blood pressure also increased with age.Conclusions: Since the distribution of home blood pressure values was affected by age and sex, age- and sex-matched reference values for home blood pressure should be established. Home blood pressure values in elderly subjects should be evaluated carefully, since these exhibit greater day-to-day variation.
