摘要目的 调查我国克山病病区居民的高血压患病情况,为我国偏远农村地区高血压的防控措施提供科学依据.方法 使用非概率抽样法于2009年在甘肃、河北、河南、黑龙江、吉林、辽宁、陕西、山东、山西、湖北、云南、四川、贵州、重庆、内蒙古15个省(市、自治区)的克山病病区中选取89个县作为调查县,并在病例搜索的基础上,选择克山病病情较重的120个村作为调查点.调查对象为调查点所有常住居民.通过问卷调查了解调查对象的基本情况,由临床医生测量调查对象血压,高血压的诊断标准参照《中国高血压防治指南》.结果 调查18岁及以上居民共计33 558人,高血压患者8 699人,检出率为25.9％(8 699/33 558),其中男性检出率为26.3％(3 532/13 408),女性检出率为25.6％(5 167/20 150);高血压患病率随着年龄的增长而升高(x2=3 348.325,P＜0.05);各级高血压的患病率分别为:一级高血压占31.8％(2 770/8 699)、二级高血压占26.1％(2 273/8 699)、三级高血压占17.2％(1 492/8 699)、单纯收缩期高血压占24.9％(2 164/8 699).结论 克山病病区高血压检出率高于全国平均患病水平(18.8％),是病区重要的公共卫生问题.病区应重视高血压的防治,有针对性地制订相应高血压的防控策略.

abstractsObjective To survey the prevalence of hypertension in population of Keshan disease endemic areas, in order to provide a scientific basis for prevention and control of hypertension in rural areas of our country.Methods One hundred and twenty villages were selected as the survey places based on case-finding from 15 provinces including Gansu, Hebei, Henan, Heilongjiang, Jilin, Liaoning, Shaanxi, Shandong, Shanxi, Hubei, Yunnan,Sichuan, Guizhou, Chongqing and Mongolia in 2009.The subjects were permanent residents in the survey places.Basic situation of all subjects was collected through the questionnaire survey and blood pressure was measured by a clinician.Diagnostic criterion for hypertension was based on the "Chinese Guidelines for the Management of Hypertension".Results Totally 33 558 subjects aged 18 and over were surveyed, including 8 699 hypertension patients.The positive rate of hypertension was 25.9％ (8 699/33 558), among that 26.3％ (3 532/13 408) were males,and 25.6％ (5 167/20 150) were females.The positive rate of hypertension increased with age (x2 =3 348.325, P ＜0.05).In the classification of hypertension, the proportion of stage 1, 2 and 3 hypertension and isolated systolic hypertension was 31.8％ (2 770/8 699), 26.1％ (2 273/8 699), 17.2％ (1 492/8 699) and 24.9％ (2 164/8 699),respectively.Conclusions The positive rates of hypertension in Keshan disease endemic areas are higher than those of the national average (18.8％).Hypertension is a serious public health problem in Keshan disease endemic areas.The strategy of hypertension prevention and control should be formulated for remote rural areas.
