辽宁省农村居民高血压患病及控制现状调查

Hypertension prevalence and its awareness,medication and control among rural residents in Liaoning province

目的了解辽宁省农村居民高血压患病和控制现状,探讨该人群血压水平变化趋势。方法采用分层整群抽样方法,抽取辽宁省5县≥35岁农村居民共5 122人进行高血压患病率流行病学调查。结果农村居民高血压患病率、知晓率、治疗率、控制率和服药控制率分别为34.6%,36.68%,21.78%,3.05%和13.99%;高血压患病率和严重程度随年龄增长明显上升(P<0.01);不同年龄组知晓率和治疗率间差异有统计学意义(P<0.01);服药控制率随年龄增长呈下降趋势,但差异无统计学意义(P>0.05)。结论辽宁省农村居民高血压普遍高发,人群中正常高值血压和患者中2、3级血压比例高,控制水平低下,亟需提高综合干预的质量。

Objective To verify the prevalence and the control rate of hypertension among rural residents in Liaoning province and to explore the trend of blood pressure variation in the population.Methods Prevalence,awareness,treatment and control of hypertension were investigated among 5 122 rural residents（≥35 years old） with a questionnaire survey.Results The prevalence of hypertension was 34.6% among the residents.Of all hypertensive patients,36.68% were aware of their high blood pressure;21.78% had antihypertensive medication,and only 3.05% had their blood pressure under control（140/90mmHg）.The prevalence and degree of hypertension increased with age increment.There were differences in knowledge rate and treatment rate between residents in different age group（P0.05）.The blood pressure control rate decreased with the age but without statistical significance（P0.05）.Conclusion The prevalence of hypertension is high in the rural residents of Liaoning province with a high ratio of grade 2 and grade 3,and the control rate of hypertension is low.There is an urgent need for comprehensive intervention of hypertension.
