成都地区自然人群的高血压患病率及血压水平15年(1992～2007)的变化

Changes of Prevalence of Hypertension and Blood Pressure Levels in 1061 Adults in Chengdu from 1992 to 2007

目的探讨成都地区自然人群高血压患病率及血压水平15年的变化情况。方法 1992年,在成都成华区采用随机抽样的方法建立了35～64岁男女两性共1365人的心血管危险因素研究队列。2007年对该队列人群进行了第2次危险因素调查。两次调查资料均完整者1061人。本研究对该1061人15年前后的高血压患病率及血压水平的变化情况进行了流行病学分析。结果①15年间男女两性各年龄组收缩压随着年龄的增长而升高,且年龄越大,升高幅度越明显。舒张压也随年龄的增长而升高,但增幅呈U字形:45～54岁组增加的幅度最小。②2007年与1992年相同年龄组间比较(2007年50～64岁组vs.1992年50～64岁组),无论男女两性,收缩压均明显增加,且男性收缩压的增加幅度大于女性;对于舒张压,男女两性均增加,但女性增幅差异无统计学意义。③15年间男女两性各年龄组的高血压患病率均增加,其中男女两性均是年龄较小组高血压患病率增幅最大,但年龄较大组的高血压患病率较高。④15年间高血压总的患病率男性由13.2%增加到51.2%,女性由14.0%增加到45.1%;在相同的年龄组(2007年50～64岁组vs.1992年50～64岁组),男女两性高血压患病率在2007年均明显高于1992年。结论随着年龄的增长,各年龄组收缩压及舒张压均明显升高,但各年龄组之间升高趋势不一致。随着年龄的增长,高血压的患病率也明显增加,年龄较小组别增加幅度最大,但年龄越大,高血压的患病率越高。男女两性高血压患病率在2007年均明显高于1992年。

Objective To investigate the changes of blood pressure（BP） levels of a general population in Chengdu,China from 1992 to 2007.Methods A baseline survey on CVD risk factors was carried out in a general population of Chengdu in 1992.A total of 1365 adults aged 35-64 years were recruited randomly.In 2007,1061 of the participants completed a follow up survey.Results ①The systolic blood pressure（SBP） levels increased with age in both men and women,and larger increase was found in older people.The diastolic blood pressure（DBP） levels also increased with age,however,the smallest increase was found in the age group of 45 to 54 years.② People of 50-64 years old in 2007 had higher SBP than those of the same age in 1992.Similar changes were also found for DBP in men,but not in women.③ From 1992 to 2007,the prevalence of hypertension increased in all of the age groups.The greater increase occurred in the younger population.④ During the 15 years,the prevalence of hypertension increased from 13.2% to 51.2% in men,and from 14.0% to 45.1% in women.People of 50-64 years old had higher prevalence of hypertension in 2007 than those of the same age in 1992.Conclusion SBP and DBP increase with age,and younger people have larger increase than older people.The prevalence of hypertension increases with age,and the greater increase also occurred in younger people.In people with the same age of 50-64 years,the prevalence of hypertension and SBP and DBP levels are higher in 2007 than in 1992,except for DBP in women.
