目的了解瑶、汉两族老年人血压与其身高、体重、血脂及血红蛋白水平的相互关系，并阐述其机理。方法选择粤北乳源县瑶、汉两族老年人，采取整群抽样，比较两组身高、体重、血压、血脂及血红蛋白水平，经统计学分析，研究影响血压水平的因素。结果汉族老年人身高、体重、血脂及血红蛋白水平均显著高于同性别瑶族老年人，同时，瑶族老年人的高血压患病率及血压水平均明显低于同性别汉族老年人，两者具有明显相关性。结论合理膳食、运动、控制血脂、体重对预防高血压有普遍意义 Objective To understand the relationship between blood pressure and height, weight, blood lipid and hemoglobin in elderly people of Yao and Han nationalities and to explain its mechanism.
