简介：目的：探讨中老年人群高脂血症、糖尿病与年龄相关性白内障（age-relatedcataract,ARC）的关系。方法：采用以医院为基础的病例对照研究方法,病例组由年龄45～85岁的360例ARC患者所组成;对照为与病例同期入住相同医院,未患与ARC有关眼病的360例患者,对照组与病例采取1：1匹配方式。采用自行设计的调查表对研究对象进行调查,内容包括人口学特征、生活方式、疾病既往史等,同时收集研究对象的临床生化检测资料,包括空腹血糖、高密度脂蛋白胆固醇（HDL-C）、总胆固醇（TC）及甘油三酯（TG）等。采用多因素Logistic回归分析,估计研究因素与ARC关联的比值比（OR）及其相应的95%可信区间（CI）。结果：调整了年龄和性别因素后,高脂血症、高脂血症病程、TC及TG与发生ARC的危险性无关（P〉0.05）,仅HDL-C下降与发生ARC的危险性升高有关（OR=1.519,95%CI：1.093～2.110,P=0.013）。在调整了多种潜在性混杂因素后,经多因素Logistic回归分析的结果显示,空腹血糖受损的研究对象发生ARC的危险性升高了73%（OR=1.734,95%CI：1.102～2.725,P〈0.001）,而已确诊的糖尿病患者发生ARC的危险性升高了94%（OR=1.938,95%CI：1.293～2.906,P〈0.001）。糖尿病病程也与ARC呈显著性正相关,糖尿病病程〈10a和10～19a的病例发生ARC的危险性分别是未患糖尿病对照的2倍（OR=2.347,95%CI：1.502～3.752,P=0.010）和3倍（OR=2.683,95%CI：1.267～5.683,P〈0.001）。结论：HDL-C下降及糖尿病可使中老年人群发生ARC的危险性增加。
