目的了解我国18～69岁成人脉压水平及脉压过宽者分布情况,并探讨其相关影响因素。方法利用2004年中国慢性病及其危险因素监测的资料,计算不同人群脉压均数和脉压过宽者(脉压≥60mmHg)所占比例,并采用t检验、方差分析和检验分析不同人群脉压水平和脉压过宽者比例的差异,并采用Logistic回归分析脉压过宽的相关因素。结果我国18～69岁成人平均脉压为45.8mmHg、脉压过宽者比例为13.5%。不论是平均脉压还是脉压过宽者比例,均表现为随年龄增长而升高。不同性别人群平均脉压之间的差异无统计学意义,40岁以前男性人群脉压过宽者比例高于女性人群,40岁以后则相反。农村地区和东部地区人群的平均脉压相对较高,东部地区脉压过宽者比例也较高。与脉压过宽相关的因素包括性别、年龄、城乡、BMI和吸烟。结论脉压在不同人群间的分布差异较大、相关因素也较多,尚需开展更多的前瞻性队列研究以确定其影响因素。
Objective To understand the distribution of pulse pressure and pulse pressure in 18 ~ 69-year-old adults in our country and to explore the related factors. Methods According to the monitoring data of chronic diseases and their risk factors in China in 2004, the proportion of pulse pressure and pulse pressure (pulse pressure≥60mmHg) in different population were calculated. The t test, ANOVA and test were used to analyze the differences of pulse rate Pressure level and pulse pressure is too wide, and Logistic regression analysis of pulse pressure is too wide. Results The mean pulse pressure of adults aged 18-69 years was 45.8mmHg, and the rate of pulse pressure was 13.5%. Whether the average pulse pressure or pulse pressure is too wide, are manifested as age increases. There was no significant difference in average pulse pressure among different sex groups. Before the age of 40, the prevalence of over-pulse in males was higher than that in females, and the opposite was true after 40 years of age. The average pulse pressure in rural areas and eastern areas is relatively high, and the proportion of people with excessive pulse pressure in eastern areas is also high. Factors related to pulse pressure include gender, age, urban-rural, BMI, and smoking. Conclusions The distribution of pulse pressure varies widely among different populations and there are many related factors. More prospective cohort studies are needed to determine the influencing factors.
