Abstract
Purpose :
To assess the prevalence and associated factors of diabetic retinopathy in a Russian population.
Methods :
The Ural Eye and Medical Study (UEMS) is a population-based study performed in the city of Ufa/Russia and in villages in a distance of 65 km from Ufa. The inclusion criterion was an age of 40+ years. Diabetic retinopathy was diagnosed on fundus photographs.
Results :
Out of a population of 7328 eligible individuals, 5899 individuals (2580 (43.7%) men) (participation rate:80.5%) participated (mean age:59.0±10.7 years (range:40-94 years)). Assessable fundus photographs were available for 4900 (83.1%) participants. Diabetic retinopathy was detected in 101/4900 individuals or 2.1% (95% confidence interval (CI): 1.7, 2.5). In binary multivariable analysis, a higher prevalence of diabetic retinopathy was associated with older age (P<0.006; odds ratio (OR): 1.05; 95%CI: 1.02,1.07), higher glucose serum concentration (P<0.001;OR: 1.17; 95%CI:1.09,1.25), history of therapy with insulin (P<0.001;OR: 3.09; 95%CI:3.08,4.94), higher systolic blood pressure (P<0.001;OR: 1.03; 95%CI:1.01,1.04), and longer history of known diabetes (P<0.001;OR: 1.06; 95%CI:1.03,1.09). In that model, diabetic retinopathy prevalence was not associated with axial length (P=0.71), rural versus urban region of habitation (P=0.08), and serum concentration of triglycerides (P=0.26).
Conclusions :
In this typical, ethnically mixed, urban and rural Russian population aged 40+ years, the prevalence of diabetic retinopathy was relatively low (101/4900 or 2.1% (95%:1.7, 2.5) and depended on known risk factors such as higher systolic blood pressure, longer duration of known diabetes, older age and worse metabolic control.
