延边州农村居民正常高值血压及影响因素分析

Prevalence and risk factors of high normal blood pressure among people in rural area of Yanbian country

目的分析延边地区农村居民正常高值血压检出率及其危险因素。方法采用简单随机方法,选取吉林省延边朝鲜族自治州安图县农村20~70岁朝鲜族与汉族常住居民,进行问卷调查、血压测量、体格检查及生化指标检测,分析其正常高值血压检出率及其影响因素。结果共调查5 903人,其中朝鲜族居民正常高值血压粗检出率为33.5%,汉族居民为39.0%,年龄调整后的标化检出率分别为40.9%和40.5%;其中朝鲜族居民正常高值血压标化检出率高于汉族居民（u=6.9,P〈0.01）;男性标化检出率高于女性（朝鲜族：u=93.8,P〈0.01;汉族：u=65.8,P〈0.01）;正常高值血压检出率随年龄增加呈逐渐降低趋势（P〈0.05）。多因素分析结果显示,男性、年龄较低、超重或肥胖者、目前饮酒者、多种心血管疾病危险因素聚集者和朝鲜族等因素,与正常高值血压患病相关性较大,其中年龄及体质指数（BMI）对正常高值血压的影响均具有剂量-反应关系。结论正常高值血压患病在延边州农村居民中较普遍,性别、年龄、超重或肥胖、饮酒、代谢综合征和民族与正常高值血压的患病密切相关。

Objective To assess the prevalence of high normal blood pressure（HNBP） and its risk factors in rural inhabitants of Yanbian country,Jilin province.Methods A total of 5 903 subjects aged 20-70 years were selected and their anthropometric and biochemical indexes were measured.Results The age-adjusted prevalence of HNBP in the Korean subjects was significantly higher than that of in the Han subjects（40.9% vs 40.5%;u=6.9,P0.01）.The age-adjusted preva-lence of HNBP had significant sex difference in both nationalities.The prevalence of HNBP decreased with the increase of age.Multiple factor analysis showed that male,lower age,body mass index（BMI）≥24 kg/m2,current alcohol drinking,with metabolic syndrome,being Korean were risk factors of HNBP.Dose-response relationships were observed between HNBP and age,BMI.Conclusion HNBP is prevalent in rural residents.The prevalence of HNBP is correlated with sex,age,alcohol drinking,metabolic syndrome,and nationality（Korean）.
