目的：探讨广西黑衣壮族和白裤瑶族人群血压水平、高血压患病率及其危险因素的差异.方法：在我们先前分层（性别与年龄）随机抽样的标本中随机选择黑衣壮族816名和白裤瑶族826名作研究对象.比较两民族人群血压水平、高血压患病率及其危险因素的差异.结果：黑衣壮族人群收缩压（16.25±2.19比15.76±2.27 kPa,P＜0.001）和脉压（6.16±1.77比5.77±1.67 kPa,P＜0.001）水平明显高于白裤瑶族人群,舒张压水平与白裤瑶族人群比较差异无统计学意义（P＞0.05）.黑衣壮族人群单纯收缩期高血压患病率（9.19％比4.24％,P＜0.001）和高血压患病率（19.49％比14.53％,P＜0.01）也明显高于白裤瑶族人群.两民族人群性别和体重指数对舒张压、吸烟对脉压以及年龄对血压的影响程度不同.结论：黑衣壮族人群的收缩压和脉压水平高于白裤瑶族人群,单纯收缩期高血压和高血压患病率也高于白裤瑶族人群.可能与他们的地理环境、饮食习惯、生活方式和遗传因素不同有关.

英文摘要：

Objective：To compare the difference in blood pressure levels,hypertensive prevalence and the risk factors between the Guangxi Hei Yi Zhuang and Bai Ku Yao populations.Methods：A total of 816 subjects of Hei Yi Zhuang nationality and 826 participants of Bai Ku Yao nationality were randomly selected from our previous stratified （gender and age） randomized samples.Blood pressure levels,hypertensive prevalence and the risk factors between the two ethnic groups were compared.Results：The levels of systolic blood pressure （SBP,16.25±2.19 vs.15.76±2.27 kPa,P＜0.001） and pulse pressure （PP,6.16±1.77 vs.5.77±1.67 kPa,P ＜0.001） were higher in the Hei Yi Zhuang than in the Bai Ku Yao populations.There was no difference in the levels of diastolic blood pressure （DBP） between the two ethnic groups （P ＞0.05）.The prevalence of isolated systolic hypertension （9.19％ vs.4.24％,P ＜0.001） and hypertension （19.49％ vs.14.53％,P ＜0.01） was also higher in the Hei Yi Zhuang than in the Bai Ku Yao populations.The influence of sex and body mass index on DBP,cigarette smoking on PP,and age on blood pressure was different between the two ethnic groups.Conclusion：The levels of SBP and PP,and the prevalence of isolated systolic hypertension and hypertension were higher in the Hei Yi Zhuang than in the Bai Ku Yao populations,which might result from different geography,dietary habit,life style,as well as genetic factors.
