Abstract: Background　Hypertension is a risk factor for cardiovascular and cerebrovascular diseases，which can lead to myocardial infarction and stroke，increasing the burden of this disease. There is lack of epidemiological data of hypertension in Gansu Province.Objective　To investigate the prevalence of hypertension in adults in Gansu Province and analyze the influencing factors.Methods　From September 2013 to December 2014，34 792 residents aged 20 to 74 in Gansu Province were selected by cluster random stratified sampling.They participated in a face-to-face questionnaire survey and underwent a physical examination and a laboratory examination conducted by qualified investigators by training according to the unified standards.The prevalence of hypertension was compared among them by characteristics.The risk factors of hypertension were analyzed by stepwise multivariate Logistic regression.Results　The prevalence of hypertension in overall participants，male and female participants was 27.73%（8 712/31 417），29.78% （4 194/14 083），and 26.06% （4 518/17 334），respectively，which were higher when compared with the age-standardized population standard in China Statistical Yearbook 2013 〔age-standardized prevalence of hypertension for the whole population，males and females was 23.24% （191 862/825 712），25.87% （213 613/825 712），and 20.98% （173 201/825 712），respectively〕.The prevalence of hypertension among the participants differed significantly by sex，age，minzu，educational level，living area，altitude of living area，economic level，smoking prevalence，drinking prevalence，BMI，family history of hypertension，waist circumference，blood glucose and blood lipid levels （P<0.05）．Stepwise multivariate Logistic regression analysis showed that sex，age，educational level，living area，altitude of living area，drinking prevalence，family history of hypertension，BMI，waist circumference， blood lipid，whether diabetes were the influencing factors of hypertension （P<0.05）．Conclusion　The prevalence of hypertension in adults in Gansu Province was high.Sex，age，educational level，living area，altitude of living area，drinking prevalence，family history of hypertension，BMI，waist circumference， blood lipid and whether diabetes were the influencing factors of hypertension，

摘要： 背景　高血压为心脑血管病的危险因素之一，可引起心肌梗死和脑卒中的发生，增加疾病负担，甘肃省高血压流行病学数据缺乏。目的　调查甘肃省成年人的高血压患病情况并分析其影响因素。方法　于2013年9月—2014年12月采用整群随机分层抽样的方法选取甘肃省34 792例20~74岁常住居民为研究对象，经培训合格的调查人员按统一标准进行面对面问卷调查、体格检查及实验室检查。比较不同特征受试者高血压患病率，采用多因素逐步Logistic回归分析高血压的危险因素。结果　甘肃省成年人高血压患病率为27.73%（8 712/31 417），男性和女性分别为29.78%（4 194/14 083）和26.06%（4 518/17 334）。根据2013年中国统计年鉴中我国的年龄段人口标准，年龄标准化高血压患病率为23.24%（191 862/825 712），男性和女性分别为25.87%（213 613/825 712）和20.98%
（173 201/825 712）。不同性别、年龄、民族、学历、区域、海拔、人均国内生产总值（GDP）、吸烟情况、饮酒情况、高血压家族史情况、体质指数（BMI）、腰围、血糖情况、血脂情况成年人高血压患病率比较，差异有统计学意义（P<0.05）。多因素逐步Logistic回归分析结果显示，性别、年龄、学历、区域、海拔、饮酒情况、高血压家族史、BMI、腰围、血脂情况、糖尿病患病情况是高血压的影响因素（P<0.05）。结论　甘肃省成人高血压患病率较高，性别、年龄、学历、区域、海拔、饮酒情况、高血压家族史、BMI、腰围、血脂情况、糖尿病患病情况是高血压的影响因素。
