无锡市滨湖区50岁及以上人群糖尿病视网膜病变患病情况调查

摘要

Objective To investigate the prevalence rate and risk factors of diabetic retinopathy (DR) in residents aged 50 and above in Binhu Area,Wuxi City.Methods Stratified cluster random sampling method was used to investigate the prevalence of DR of residents aged 50 and above from January to December 2010.Detailed medical history,general examination,visual acuity,slit lamp microscope,direct ophthalmoscopy and blood sample testing were conducted for all selected subjects.DR diagnostic criteria refer to the 2002 International DR classification criteria.Unilateral or bilateral DR was both considered as DR patients.x2 test was used for statistical analysis of risk factors,and independent risk factors were screened by SPSS 17.0 software.Results A total of 6150 residents underwent the examination with a participating rate of 91.5 ％.Seven hundred and three residents were diagnosed as with diabetes,in which 40 were unable to record the fundus condition due to opaque refractive media.Among the rest 663 diabetic patients,36 (5.4 ％) were DR patients.There were 34 non-proliferative DR (5.1 ％) and two proliferative DR (0.3％).The duration of diabetes and fasting blood-glucose were the independent risk factor of DR (r=0.008,0.009; P＜0.05).Conclusions The prevalence rate of DR is low in the residents aged 50 and above in Binhu Area,Wuxi City.The duration of diabetes and fasting blood-glucose level were confirmed as the independent risk factor of DR.%目的 调查无锡市滨湖区50岁及以上人群中糖尿病视网膜病变(DR)的患病情况,分析其影响因素.方法 2010年1～12月采用分层整群随机抽样的方法,对50岁及以上人群进行DR普查.对所有受检者均进行详细的病史询问、全身检查,视力、裂隙灯显微镜、直接检眼镜检查和血样采集.DR诊断标准参照2002年国际DR分型标准.单眼或双眼DR均入选为DR患者.采用x2检验统计分析与患病率相关的影响因素,通过逐步回归分析筛选出独立影响因素.结果 实际受检者6150人,受检率91.5％.检出糖尿病患者703例.除外屈光间质混浊无法记录眼底情况者40例,纳入分析663例.确诊DR 36例,占糖尿病患者的5.4％.非增生型DR 34例,占DM患者的5.1％；增生型DR 2例,占DM患者的0.3％.糖尿病病程(r=0.008)、空腹血糖(r=0.009)为影响DR患病率的独立因素(P＜0.05).结论 无锡市滨湖区50周岁及以上人群DR患病率较低,糖尿病病程和空腹血糖是影响DR患病率的独立因素.
