目的观察连云港农村社区中老年高血压人群脉压水平的分布,并探讨其相关的影响因素。方法 2008-10-2009-07,在连云港市赣榆和东海两县农村社区筛选45～75岁原发性高血压患者,进行流行病学问卷调查、血压测量、体格检查等。结果共调查20127人,其中未服用降压药物且无关键变量缺失者共9998人纳入本研究。总人群平均脉压为(73.2±18.5)mmHg[男性(70.1±19.2)mmHg,女性(75.1±17.8)mmHg,P<0.01];脉压过宽者(脉压≥60mmHg)占78.2%,其中男性占70.8%,女性占83.0%(P<0.01)。脉压水平和脉压过宽的比例均随着年龄增高而增高,并与高血压严重程度呈正比。多元线性回归显示,脉压的影响因素包括年龄、性别、心率、空腹血糖、体质量指数、血压值等级和吸烟。结论连云港农村社区中老年高血压人群脉压水平女性高于男性,且随着年龄和高血压等级的上升而增加,脉压增高可能是年龄、性别、高血压、血糖、吸烟等多种因素综合作用的结果。
Objective To observe the distribution of pulse pressure in middle-aged and elderly hypertensive population in rural communities of Lianyungang and to explore the related factors. Methods From October 2008 to July 2009, 45-75-year-old patients with essential hypertension were screened in rural communities of Ganyu and Donghai counties in Lianyungang for epidemiological survey, blood pressure measurement and physical examination. Results A total of 20127 people were surveyed. Among them, a total of 9998 people who did not take antihypertensive drugs and lack of key variables were included in the study. The average pulse pressure of the general population was (73.2 ± 18.5) mmHg [male (70.1 ± 19.2) mmHg, female (75.1 ± 17.8) mmHg, P <0.01] Men accounted for 70.8%, women accounted for 83.0% (P <0.01). The ratio of pulse pressure and pulse pressure is increased with age, and is proportional to the severity of hypertension. Multiple linear regression showed that the influencing factors of pulse pressure included age, sex, heart rate, fasting blood glucose, body mass index, blood pressure level and smoking. Conclusion The pulse pressure level of middle-aged and elderly population in rural community of Lianyungang is higher than that of male, and increases with age and the level of hypertension. The increase of pulse pressure may be the result of age, sex, hypertension, blood sugar, smoking and other factors The result of the action.
