目的探讨蒙古族居民高血压各影响因素之间关系及各自作用的大小。方法选择内蒙古科左后旗朝鲁吐乡和奈曼旗固日班花乡的32个行政村,调查所有年龄20岁以上居民。采用面对面调查方法,收集人口学特征资料以及吸烟、饮酒等生活方式,测量血压、身高、体重、腰围和臀围。采集血标本,检测血糖、血脂、C-反应蛋白等。使用SAS8.1软件进行统计分析和通径分析。结果共调查2589人,高血压患病率为37.39%;其中男性1064人,患病率为45.58（95%CI=42.5～48.63）;女性1525人,患病率为31.67%（95%CI=29.34～34.07）。通径分析结果表明,不论男性还是女性,年龄、高血压家族史、体质指数和血糖均对高血压有直接效应,男性通径系数分别为0.389,0.309,0.133,0.086;女性分别为0.470,0.217,0.281,0.080。此外,饮酒、腰臀比和血脂异常对男性高血压有直接效应,通径系数分别为0.173,0.104,0.154;而C-反应蛋白对女性高血压有直接效应,通径系数为0.093。未发现吸烟对高血压有直接效应。结论男性高血压患病率高于女性;男性高血压危险因素按其作用大小依次为年龄、家族史、饮酒、血脂异常、体质指数、腰臀比和血糖水平：女性为年龄、家族史、体质指数、C-反应蛋白和血糖水平。

英文摘要：

Objective To determine the prevalence of hypertension and explore the relationship among risk factots of hypertension and their effects on hypertension in Mongolian people.Methods Total 32 villages in Kezuohou Banner and Naiman Banner in Inner Mongolia,were selected as study field and residents aged 20 and above were served as study subjects,demographic data and life style including smoking cigarette and alcohol intake were investigated by face to face method,and their blood pressures,height,body weight,waist and hip circumference,were measured by standardized methods,and their blood samples were collected and fasting plasma glucose level,blood lipids and C-reactive protein were examined for all subjects.Common statistics and path analysis were conducted to identify the associations among risk factors and association between risk factors and hypertension.Results A total of 2589 subjects,1064 male and 1525 female,were recruited in the study.The crude prevalence of hypertension was 37.39% for all subjects and 45.58% for men [95% confidence interval（CI）42.56%～48.63%] and 31.67% for women（95%CI 29.34～34.07%）.The path analysis demonstrated age,family history of hypertension,BMI and blcod glucose 1evel had direct effects on hypertension in both sexes（path coefficients respectively were 0.389,0.309,0.133,0.086 for male and 0.470,0.27,0.281,0.080 for female）,and alcohol intake,WHR,dyslipidemia had effects on hypertension only in male（path coefficients were 0.173,0.104,0.154 respectively）,and C-reactive protein had effect on hypertension only in female（path coefficient was 0.093）.Conclusion The prevalence of hypertension in male population was higher than that in female in Mongolian people.The risk factors of hypertension orderly were age,family history of hypertension,alcohol intake,dyslipidemia,BMI,WHR and blood glucose level in male population,and age,family history of hypertension,BMI,reactive protein in women.Smoking cigarette was found a negative correlation with BMI,but it had no direct effe
