浙江省成年居民血脂异常患病率及其分布特征的现况分析

目的 了解浙江省成年居民血脂异常现患率,为进一步制定血脂异常预防控制策略提供依据。 方法 采用多阶段分层整群随机抽样的方法,选取18周岁常住人口为调查对象,测定其血脂情况。 结果 共有效调查成年居民17 437人,按年龄、性别和地区加权调整后,浙江省成年人血脂异常患病率为49.19%(粗患病率为49.86%),其中男性(54.29%)高于女性(43.80%),城乡差异无统计学意义。青年组(18~44岁)、中年组(45~59岁)和老年组(60岁)人群的患病率分别为50.07%、49.33%和45.87%,血脂异常年轻化趋势明显。各类分型中以低高密度脂蛋白胆固醇血症患病率最高(42.28%),其中男性青年组患病率达51.70%;甘油三酯升高率(12.14%)与边缘升高率(10.94%)合计达23.08%;胆固醇边缘升高率(10.42%)是患病率(1.93%)的5.4倍。与2002年相比,浙江省血脂异常患病率有所增加,其中青年男性增加明显。调查发现血脂异常知晓率为11.25%,青年人群呈现低知晓率、高患病率的特点。 结论 浙江省近半数成年居民血脂异常,其中以低高密度脂蛋白胆固醇血症为主,患病人群年轻化趋势明显,知晓率有待提高,应引起重视,积极进行干预控制。

Prevalence of dyslipidemia and its distribution among adults,a cross-sectional study in Zhejiang

Objective To understand the prevalence of dyslipidemia among adults in Zhejiang and provide evidence for the development of the prevention and control measure.Methods The study subjects were selected among local redidents aged ≥18 years by multi stage stratified cluster random sampling to conduct blood lipids detection.ResultsTotally 17 437 persons were surveyed,The adjusted prevalence of dyslipidemia was 49.19%(the crude prevalence: 49.86%).The prevalence in males(54.29%) was significantly higher than that in females(43.80%).The difference between urban area and rural area had no statistically significance.The adjusted prevalence was 50.07% in age group 18-44 years,49.33% in age group 45-59 years and 45.87% in age group≥60 years.The prevalence of dyslipidemia in young people was high.The prevalence of low high-density lipoprotein cholesterol(HDL-C) was highest(42.28%) among different types of dyslipidemia and was as high as 51.70% in young males.The prevalence of abnormal triglyceride was 23.08%(the rate of high triglyceride: 12.14% and the rate of high triglyceride at cut off value: 10.94%).The prevalence of cholesterolemia at cut off value(10.42%) was 5.4 times higher than that of cholesterolemia(1.93%) Compared with the result of a study in 2002,the standardized of dyslipidemia increased in Zhejiang,especially in youth males.The study also found that the awareness of dyslipidemia was only 11.25%,the young group was characterized with high prevalence but low awareness.Conclusion Nearly half of the adults in Zhejiang are suffering from dyslipidemia.Low HDL-C accounted for the major part,and dyslipidemia is more prevalent in young people than before.It is necessary to increase the awareness of dyslipidema in local population and conduct active intervention to prevent dyslipidema.
