title: Obesity--a risk factor for diabetic retinopathy in type 2 diabetes?
abstract: The aim of the study was to investigate whether obesity, independently or associated with other risk factors, increases the risk for the diabetic retinopathy in type 2 diabetic persons. Data of 156 diabetic persons that have consecutively attended the Outpatient Department in the Vuk Vrhovac Institute in Zagreb during two months period were studied. According to their body mass index (BMI) they were divided into three groups: group 1 (BMI < or = 25; n = 49), group 2 (BMI 26-29.9; n = 52) and group 3 (BMI > or = 30; n = 55). The three groups did not differ in age, duration of diabetes, treatment, cholesterol, HDL-cholesterol and triglycerides. With increase in BMI, we observed a significant deterioration of HbA1c and a significant increase in LDL-cholesterol, systolic and diastolic blood pressure. Statistical analyses shown that the prevalence of retinopathy increased significantly with higher body weight (gr. 1: 40.8%, gr. 2: 63.4%, gr. 3: 63.6%;p < 0.05), but also with correlation to quality of metabolic control (HbA1c) and systolic blood pressure. Therefore, obesity may be, because of its significant correlation to quality of metabolic control (HbA1c) and systolic blood pressure, considered as risk factor for diabetic retinopathy in type 2 diabetic persons.
