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 understand the prevalence and control of hypertension among rural residents in Liaoning Province and to explore the changing trend of blood pressure in this population. Methods A stratified cluster sampling method was used to collect 5 122 rural residents aged 35 or above from 5 counties of Liaoning Province for epidemiological investigation of prevalence of hypertension. Results The prevalence, awareness rate, treatment rate, control rate and medication control rate of rural residents were 34.6%, 36.68%, 21.78%, 3.05% and 13.99% respectively. The prevalence and severity of hypertension were significantly increased with age (P <0.01). The difference of awareness rate and treatment rate between different age groups was statistically significant (P <0.01). The control rate of taking medicine decreased with age, but the difference was not statistically significant (P> 0.05). Conclusions High prevalence of hypertension among rural residents in Liaoning Province is high. Normal population high blood pressure and patients with high grade 2 and 3 high blood pressure, low level of control, it is urgent to improve the quality of comprehensive intervention.
