The Prevalence And Risk Factors Of Diabetic Retinopathy In Some Areas Of Northern Xinjiang

Objective: To determine the prevalence and risk factors of diabetic retinopathy(DR)among people with diabetes in some areas of northern Xinjiang.Methods: From January to February 2019,2242 patients with confirmed diabetes were collected in some areas of northern Xinjiang.General information was obtained,height and weight were measured,and retinal photographs of both eyes were collected.Caculating the prevalence of DR and VTDR,the risk factors of DR and VTDR was analyzed by logistic regression model.Results:(1)Among the 2,242 subjects,2080 had graded binocular images.The prevalence of DR was 21.9% in 455 DR patients.The prevalence of Vision-Threatening Diabetic Retinopathy(VTDR)in 227 patients was 10.9%.(2)In univariate analysis,"family history","course of diabetes","fasting fingertip blood glucose","hypertension" and "insulin treatment" had statistical differences with the prevalence of DR(P < 0.05),"type of medical insurance","family history","course of diabetes","fasting fingertip blood glucose","hypertension" and "insulin treatment" had statistical differences with the prevalence of VTDR(P < 0.05)(3)Binary Logistic regression analysis showed that "fasting glucose in fingertips","course of diabetes","family history" and "insulin treatment" were independent risk factors for the occurrence of DR."Fingertip fasting glucose","diabetic course","insulin treatment","hypertension" and "blood glucose monitoring" are independent risk factors affecting the occurrence of VTDR.Conclusion:The prevalence of DR in some areas of northern Xinjiang was 21.9%.The course of diabetes,fasting glucose in fingertips and insulin treatment are independent risk factors for DR.We should pay attention to these risk factors,timely intervention,reduce visual loss.
