An Investigation on Diabates Mellitus and hyperlipidemia in Inner Mongolia, China

目的：了解内蒙古牧区牧民和农民糖尿病、高脂血症、高血压的患病情况及其与生活方式的关系。方法：于1999年10月和2000年10月对内蒙古草原牧区蒙古族牧民和农民进行调查。测量血压。空腹采血测定血糖、总胆固醇和高密度脂蛋白胆固醇。同时进行口服葡萄糖耐量试验。测定尿肌酸、尿钠以估算盐的摄入量。结果：虽然牧民的平均年龄低于农民，但牧民的血压水平却明显高于农民。游牧民高血压患病率(49.8%)明显高于农民(8.2%)。游牧民的总胆固醇高于农民，但高密度脂蛋白胆固醇低于农民。牧民和农民的糖尿病患病率均较低，分别为2.1%和2.2%。结论：蒙古族牧民的血压水平和高血压患病率明显高于同民族农民。牧民高血压的危险因素似乎是高盐摄入量和肥胖，这可能是由于他们的饮食造成的。

PURPOSE: To investigate the prevalence of diabetes mellitus, hyperlipidemia and hypertension in the nomads and farmers as well as the relationship with their lifestyles.METHOD: Mongolian nomads in grassland and farmers in agriculture region of Inner Mongolia were investigated in Oct. of 1999 and 2000. The blood pressure was measured. The fasting blood was collected to measure the blood glucose, total cholesterol and HDL-cholesterol. Oral glucose tolerance test were also performed. The creactine, sodium in urine were measured for estimating the intake of salt. The physical examination were conducted.RESULT: Although the average age of nomads was lower than that of the farmers, the blood pressure level was much higher in nomads. Moreover, the ratio of hypertension in the nomads (49.8%) was much higher than in the farmers (8.2%). The total cholesterol of nomads was higher than that of farmer, but the HDL-cholesterol of nomads was lower compared with farmer. The ratio of diabetes mellitus was low both in the nomads (2.1%) and farmers (2.2%).CONCLUSION: The level of blood pressure and prevalence of hypertension were much higher in Mongolian nomads than in farmers of the same ethnic. The risk factors for nomads' hypertension seem to be high salt intake and obesity which may result from their diets.
