目的 探讨北京城区老年人长时血压变异性的特点及其相关因素.方法 采用整群随机抽样方法在北京市东城区(原崇文区)和石景山区抽取≥60岁非脑卒中人群,对其进行体格检查并随访血压值,分析老年人长时血压变异性特点,运用多重线性回归法探讨血压变异性的相关因素.结果 老年高血压人群(593例)血压变异性明显高于老年非高血压人群(801例)[收缩压变异性为(13.8±2.1)mmHg(1 mmHg=0.133 kPa)比(12.0±2.1)mmHg,t=-13.89,P<0.01;舒张压变异性为(9.3±1.7) mmHg比(8.6±1.8)mmHg,t=-8.45,P<0.01].男性收缩压<120、120~139、140~ 159、160~179、≥180 mmHg者分别为93、322、74、9、6例,其收缩压变异性分别为(10.8±2.4)、(12.4±1.9)、(13.6±2.4)、(16.1±2.4)、(23.9±4.5) mmHg,女性分别为463、310、86、28、3例,其收缩压变异性分别为(11.6±2.4)、(12.7±2.0)、(14.2±2.4)、(17.5±2.6)、(26.2±1.8) mmHg.男性舒张压<80、80~89、90 ~99、100~ 109 mmHg、≥110 mmHg者舒张压变异性分别为(8.4±1.9)、(8.7±1.7)、(9.6±1.5)、(10.2±1.3)、(13.5±5.0) mmHg,女性分别为(8.8±1.7)、(8.9±1.6)、(9.6±1.3)、(10.7±1.0)、(15.6±0.8)mmHg.男性60~64、65 ~69、≥70岁者分别为172、129、203例,其收缩压变异性分别为(11.9±2.7)、(12.1±2.1)、(13.2±2.7)mmHg,舒张压变异性分别为(8.5±1.8)、(8.6±1.8)、(9.1±1.9)mmHg;女性60 ~ 64、65~69、≥70岁者分别为248、270、372例,其收缩压变异性分别为(12.3±2.7)、(12.8±2.1)、(13.4±2.6) mmHg,舒张压变异性分别为(8.7±1.6)、(8.9±1.6)、(9.3±1.8) mmHg;老年人血压变异性有随年龄增大而升高的趋势(P<0.01),65 ~69岁组血压变异性高于同龄男性(P<0.05).无论男性、女性,老年人血压变异性有随血压水平的升高而增大的趋势;女性收缩�
Objective To investigate the characteristics and related factors of long-term blood pressure variability in the elderly in urban area of Beijing.Methods A survey was conducted among a non-stroke population over 60 years old from Dongcheng district (former Chongwen district) and Shijingshan district of Beijing,using stratified cluster random sampling method; physical examination and blood pressure monitoring were taken in each follow-up.Multiple linear regressions were used to analyze the characteristics and related factors of long-term blood pressure variability in the elderly.Results Blood pressure variability in hypertensive patients was significantly higher than that in non-hypertensive patients [systolic blood pressure variability was (13.8 ± 2.1) mmHg vs (12.0 ±2.1) mmHg,t =-13.89,P 〈0.01 ; diastolic blood pressure variability was (9.3 ± 1.7) mmHg vs (8.6 ± 1.8) mmHg,t =-8.45,P 〈 0.01].In the groups of systolic blood pressure 〈 120 mmHg,120-139 mmHg,140-159 mmHg,160-179 mmHg,≥ 180 mmHg,systolic blood pressure variability was (10.8 ± 2.4),(12.4 ± 1.9),(13.6 ± 2.4),(16.1 ± 2.4),(23.9 ± 4.5) mmHg respectively for males,and it was (11.6 ± 2.4),(12.7 ± 2.0),(14.2 ± 2.4),(17.5 ± 2.6),(26.2 ± 1.8) mmHg respectively for females.In the groups of diastolic blood pressure 〈 80 mmHg,80-89 mmHg,90-99 mmHg,100-109 mmHg,≥ 110 mmHg,diastolic blood pressure variability was (8.4 ± 1.9),(8.7 ± 1.7),(9.6 ± 1.5),(10.2 ± 1.3),(13.5 ± 5.0) mmHg respectively for males,and it was (8.8 ± 1.7),(8.9 ± 1.6),(9.6 ± 1.3),(10.7 ± 1.0),(15.6 ± 0.8) mmHg respectively for females.In the groups of age 60-64,65-69,≥70,systolic blood pressure variability was (11.9 ±2.7),(12.1 ± 2.1),(13.2 ± 2.7) mmHg respectively for males ; diastolic blood pressure variability was (8.5 ± 1.8),(8.6 ± 1.8) and (9.1 ± 1.9)mmHg respectively for males.In the groups of age 60-64,65-69,≥70,systolic bl
