农村中老年高血压人群收缩压与舒张压的差异分析

Analysis on the different effect of systolic and diastolic blood pressure in middle-aged and elderly with hypertension in rural

目的 了解收缩压、舒张压在农村居民未控制高血压人群中的作用。方法 以整群抽样的方法对三峡坝区农村 35 a以上居民进行原发性高血压流行病学调查。结果 三峡坝区农村未控制高血压人群中 ,单纯收缩期高血压占 37.9% ,单纯舒张期高血压占 15 .8% ,混合型高血压占4 6 .3%。高年龄组的知晓率、治疗率要高于低年龄组。两年龄组人群中血压单独按收缩压进行分级 ,正确比例远高于单独按舒张压分级。达到控制目标收缩压所需降压值在单纯收缩期高血压和混合型高血压两亚型的高年龄组均要高于低年龄组。而单纯舒张期高血压的低年龄组所需降压值要高于高年龄组。结论 在三峡坝区农村中老年人群中单纯收缩期高血压和混合型高血压是主要的血压亚型。

Objective To study the different effect of systolic and diastolic pressure in middle aged and elderly with hypertension in rural. Methods A cluster sampling cross sectional survey was carried out on rural residents over 35 years old in three gorge dam area. Results In uncontrolled hypertension, the percent of systolic and diastolic hypertension was 46.3% and the percent of isolated systolic hypertension was 37.9% and the percent of isolated diastolic was 15.8%. Hypertension awareness and treatment in older group was higher than that in younger group. The accurate percent of staging by systolic blood pressure alone was higher than that of staging by diastolic blood pressure alone in two age groups. Subjects in older group who had isolated systolic hypertension and systolic and diastolic hypertension required a greater reduction of systolic pressure than that in the younger group to attain a systolic blood pressure treatment goal. On the other hand, the diastolic blood pressure reduction in younger group of isolated diastolic hypertension was higher than that in the older group. Conclusions Systolic and diastolic hypertension and isolated systolic hypertension were the majority subtype of uncontrolled hypertension in three gorge dam rural area. The elevation of systolic pressure was the main problem in uncontrolled hypertension.
