北京地区2740人的血压水平10年(1992-2002)变化情况

The Change of Blood Pressure Level During Ten Years (1992 -2002) for individuals in 2 740 Subjects Years in Beijing

目的探讨北京地区人群个体血压水平10年的变化情况。方法采用前瞻性队列研究的方法,于1992年对北京大学社区和首钢地区35-64岁人群,进行了基线心血管病危险因素调查,并持续10年对心血管病的发病情况进行了随访。在2002年对相同人群再次进行了危险因素调查,对两次调查结果中血压水平的变化情况进行了流行病学分析。结果(1)10年间平均收缩压水平随年龄的增长而持续增加;平均舒张压水平在55岁以前呈上升变化,在55-64岁组呈轻度下降;(2)1992年与2002年相同年龄组间比较(例如1992年45-54岁与2002年45-54岁),平均收缩压水平、平均舒张压水平及高血压患病率均明显增加;(3)10年间总的高血压患病率南27.6％增加到48.8％,55-64岁组高血压患病率最高,35-44岁组高血压患病率增加的幅度最大;单纯收缩期高血压(ISH)在全部高血压患者中所占比例随年龄的增长明显增加,65-岁组的ISH所占比例最高,达61.8％;(4)1992年血压在120/80mmHg以下、120-129/80-84mmHg、130-139/85-89mmHg3个亚组的人群到2002年成为高血压患者的比例分别为22.2％、44.7％和64.3％。结论收缩压和舒张压随年龄的增长呈现不同的变化;目前45-64岁年龄组人群的平均收缩压水平、平均舒张压水平及高血压患病率,均较10年前45-64岁年龄组人群高;随年龄的增长?

Objective To explore the change of the individual blood pressure(BP) level in ten years. Methods In this prospective study, a survey on the risk factor of cardiovascular disease was carried out in a cohort of 2 740 subjects in 1992, including males and females, and ages 35-64 years. The cohort was continuously followed up for 10 years to 2002. Results (1)From 1992 to 2002, the systolic blood pressure(SBP) level increased with age in both males and females, the diastolic blood pressure(DBP) level increased before 55 age group and decreased in 55 - 64 age group; (2)SBP, DBP and hypertension prevalence was increased in 2002 than 1992 in the corresponding age group; (3) hypertension prevalence was increased from 27. 6 to 48. 8%,with highest prevanlence rate in subjects of ages 55 to 64 years, and greatest increasing extent in subjects of ages 35 to 44 years. The incidence of isolated systolic hypertension(ISH) was predominent(61. 8%) in population between 65 to 74 years, and increased with age;(4) the prevalence of hypertension was 22. 2%, 44. 7% and 64. 3% in 2002 for the individuals whose baseline BP level was < 120/80 mm Hg, 120-129/80 - 84 mm Hg, 130-139/85-89 mm Hg, respectively. Conclusion SBP and DBP change differently with age. SBP, DBP, and hypertension prevalence of individuals between 45 to 64 years in 2002 were increased as compared with those in 1992. Prevalence rate of ISH was increased with age. The incidence rate of hypertension was significantly greater in persons whose baseline BP level was 12-139/80- 89 mm Hg than that below 120/80 mm Hg.
