东莞市东部地区35岁以上居民血脂水平及分布特征

目的探讨东莞市东部地区35岁以上居民血脂水平及分布特征。方法 2011年7月至2012年4月,采用整群抽样的方法,对东莞市横沥镇35岁及以上的19 058户籍居民进行问卷调查及总胆固醇(total cholesterol,TC)、三酰甘油(triacylglycerol,TG)、高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)和低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C)检测。结果完成问卷调查、血脂检测共9 921人。血脂异常标化患病率为35.47%。TC、TG、HDL-C、LDL-C浓度分别为(5.20±1.02)mmol/L、(1.56±1.34)mmol/L、(1.49±0.38)mmol/L、(3.03±0.90)mmol/L。血脂异常类型以高TG、高TC为主。男性49岁以下年龄段组的TC、LDL-C浓度及LDL-C血症患病率较女性同年龄段组高,50岁以上较女性低,差异有统计学意义(P<0.05)。男女间TC、TG、HDL-C浓度及高TC、高TG、低HDL-C血症患病率比较,差异均有统计学意义(P<0.05)。结论东莞市东部地区35岁以上居民TC、TG、LDL-C浓度及高TC、高TG、高LDL-C患病率较高;血脂异常类型以高TG、高TC为主;中年男性及更年期以后女性血脂水平较高。

Distribution characteristics of plasma lipid levels in residents above the age of 35 years in the eastern region of Dongguan city

Objectives To study the plasma lipid levels and the distribution characteristics in residents above the age of 35 years in the eastern region of Dongguan city. Methods From July 2011 to April 2012, a cluster sampling method was conducted on 19 058 residents above the age of 35 years in Hengli town, Dongguan city. Total cholesterol （TC）, triacylglycerol （TG）, high-density lipoprotein cholesterol （HDL-C）, low-density lipoprotein cholesterol （LDL-C） were determined. Results There were 9 921 individuals completed the questionnaire and determination. Standardized prevalence of dyslipidemia was 35.47%. Levels of TC, TG, HDL-C and LDL-C were （5.20±1.02） mmo｜/L, （1.56±1.34） mmol/L, （ 1.49±0.38 ） mmol/L, （3.03±0.90） mmol/L respectively. Main types of dyslipidemia were predominant elevation of TG and TC. Levels of TC and LDL-C, incidence rate were higher in males under 49 years than those in females of the same age, while they were lower in those above 50 （P〈0.05）. Difference of TC, TG, HDL-C levels between males and females were statistically significant, so was the prevalence of elevated TC, TG and reduced HDL-C （P〈0.05）. Conclusions Both high levels of TC, TG, LDL-C and high prevalence of elevation of TC, TG, LDL-C are found in residents over 35 years in the eastern region of Dongguan. Hypertriglyceridemia and hypereholesterolemia are predominant kinds of dyslipidemia. The plasma lipid level is high both in males of middle age and females after menopause.
