Prevalence and Risk Factor Analysis of Type 2 Diabetic Retinopathy in the Dai Ethnic Region of Yunnan Province
This study aimed to explore the prevalence of DR and its associated risk factors among T2DM hospital-ized patients in the Dai ethnic region of Yunnan Province,China.We conducted a retrospective analysis of clini-cal data and color fundus photography results from 522 T2DM patients admitted to the Departments of Ophthal-mology and Endocrinology at the People's Hospital of Dehong Prefecture,Yunnan Province,from January 2020 to December 2022.Patients were categorized into the Non-Diabetic Retinopathy(NDR)group and the DR group based on the results of color fundus photography.The R 4.0.3 statistical software was used for single-factor a-nalysis to compare the sociodemographic data,laboratory test indicators,and relevant medical histories between the two groups.Binary logistic regression analysis was further employed to screen for potential risk factors for the occurrence of DR.Among the 522 T2DM patients,there were 369 cases in the NDR group and 153 in the DR group,resulting in a DR prevalence rate of 29.31%among hospitalized T2DM patients in Dehong Prefecture,Yunnan Province.The number of Dai patients(64 cases,41.83%),patients with a diabetes duration of over five years(5-10 years:62 cases,11-15 years:27 cases,16-20 years:38 cases,>20 years:5 cases),patients with hypertension(116 cases,75.82%),and patients with elevated urea levels and reduced eGFR(35 cases,22.88%)in the DR group were all higher than those in the NDR group.Multivariate logistic regression analysis indicated that being Dai,having a diabetes duration of over five years,and comorbid hypertension might be inde-pendent risk factors for the development of DR,with the odds ratios(OR)and 95%confidence intervals(CI)being 2.05(1.24~3.38)for Dai ethnicity,3.50(1.97~6.22)for a diabetes duration of 5-10 years,6.57(3.17~13.64)for 11-15 years,12.95(6.04~27.77)for 16-20 years,3.56(1.05~12.01)for over 20 years,and 1.85(1.10~3.11)for comorbid hypertension.The DR prevalence rate among hospitalized T2DM pa-tients in Dehong Prefecture,Yunnan Province,is 29.31%.Being Dai,having a diabetes duration of over five years,and comorbid hypertension are independent risk factors for the development of DR.
