广东乳源县瑶族老年人血压与低身高、低体重、低脂血症及低血红蛋白的相关性

Correlation between low Blood Pressure and Low Height,Low Weight, Low Blood Lipids and Low Haemoglobin in the Old Yao and Han in Ruyuan District of Guangdong

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。

Aim\ This study is conducted to compare the level of blood pressure(BP) and prevalence of hypertension between the old Yao people and Han people,and analyze the relation between height,weight,blood lipids, haemoglobin and the level of BP and the prevalence rate of hypertension.\ Methods\ Two randomized cohorts of old Yao people and Han people were surveyed. The sample data collection,diagnostic criteria were identical. Prevalence of hypertension,level of BP,smoking habit,alcohol and salt consumption,height,weight, blood lipids and heamoglobin in these two groups were compared.\ Results\ The height,weight, blood lipids and heamoglobinwere lower in Yao than Han old persons(P>005).The level of BP, prevalence rate of hypertension were lower in Yao than in Han elder people(P>005) as well.\ Conclusion\ Our epidemiological survey showed that Low height,low blood lipids and low haemoglobin may decrese the risk of hypertension.Reasonable diet,more exercise,reduction of overweight,and appropriately lowering the blood lipids may decrease the prevalence of hypertension.
