甘肃省裕固族地区中老年居民血脂水平的流行病学调查

摘要

目的 观察甘肃省裕固族地区中老年居民血脂水平及血脂异常状况,为该地区血脂异常的防治工作提供科学依据.方法 采用整群随机抽样方法,对长期居住在甘肃肃南裕固族自治县的511名中老年居民进行现况调查,检测血浆TC、TG、LDL-C、HDL-C水平.结果 ①高TC、高TG、高LDL-C血症为该地区人群血脂异常的主要类型,异常发生率分别为42.86%、60.86%、53.62%.②血脂异常与年龄、性别有关.60岁以上女性TC及LDL-C显著高于男性(P＜0.05).③裕固族中老年TC、LDL-C水平高于汉族,有显著性差异(P＜0.05).④高血压组TC、LDL-C水平与血压正常组有显著性差异(P＜0.01,P＜0.05),超重肥胖组TC、TG、LDL-C水平均高于正常体重组(P＜0.05).结论 该地区中老年居民为血脂异常的高发人群,血脂异常与超重肥胖、腹型肥胖、高血压具有显著相关性.%Objective To study the level of blood lipid and the prevalence rate of abnormal blood lipid level in the mid-aged and elderly people in Yugu minority area of Gansu province, so as to provide evidence to prevent and cure abnormal blood lipid in the future.Methods Cross-sectional investigation in 511 mid-aged and elderly people in Yugu minority autonomous region were carried out by cluster random sampling.The plasma levels of total cholesterol (TC), triglyceride(TG), low-density li poprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C) were determined.Results ( 1 ) High TC, high TG and high LDL-C were the main types of abnormal blood lipid in this area, the prevalence rates were 42.86％, 60.86％ and 53.62％ respectively.(2)The prevalence rate of abnormal blood lipid was related with age and gender.( 3 ) The levels of blood lipid in the mid-aged and elderly people of Yugu minority were significanfiy higher than those of Han nationality ( P ＜ 0.05 ).(4) The plasma levels of TC and LDL-C in hypertension group were significandy greater than those of normal group ( P ＜ 0.01, P ＜ 0.05 ).The plasma levels of TC, TG and LDL-C in overweight group were higher than those of normal weight group.Conclusions The people in Yugu minority area of Gansu province is high-risk population of abnormal blood lipid.Abnormal blood lipid is related with overweight, abdomen obesity and hypertension.
