Background: Diabetic retinopathy (DR), an imperative sequel is posing huge threat of blindness because of substantial prevalence of diabetes in the population of Punjab. Indepth understanding of its risk factors is relatively unexplored in this region.
Objective: To identify the prevalence and risk predictors of diabetic retinopathy in the population of Punjab.
Methods: A cross sectional study was conducted in 562 type 2 diabetic subjects of age >45 years. Consenting subjects were tested with dilated pupil fundoscopy and categorised into non proliferative (NPDR) and proliferative diabetic retinopathy (PDR) according tomodified Airlie House Classification.
Results: Univariate regression analysis revealed advancing age (>55 years), duration of diabetes (DOD) >10 years, systolic (>120mmHg), diastolic blood pressure (>80mmHG), smoking, sedentary life style, total cholesterol (>200mg/dl), low density lipoproteins (LDL) cholesterol (>150mg/dl) and high density lipoprotein (HDL) cholesterol (< 40 mg/dl) as risk factors. In multivariable logistic regression analysis, age>65 years, DOD>10 years, SBP>120mmHg, DBP>80mmHg, total cholesterol >200mg/dl, sedentary life style and smoking were observed to be substantial risk variables influencing independently the risk of DR in the population of Punjab.
Conclusion: Higher prevalence of NPDR (33.98%) and PDR (31.50%) existed in the population of Punjab, which is regulated by advancing age (>65 years), DOD>10 years, SBP>120mmHg, DBP>80mmHg, total cholesterol >200mg/dl, sedentary life style and cigarette smoking.
