Abstract Background To examine the prevalence of chronic kidney disease (CKD) and its associations in a Russian population. Methods Out of 7328 eligible individuals, the population-based cross-sectional Ural Eye and Medical Study included 5899 (80.5%) individuals aged 40+ years and undergoing a detailed medical examination. The estimated glomerular filtration rate (eGFR) was calculated using the Chronic-Kidney-Disease-Epidemiology-Collaboration (CKD-EPI) equation. Results The mean eGFR was 72.3 ± 19.1 mL/min/1.73m2 (median:70.3 mL/min/1.73m2). Prevalence of CKD stage 3a (eGFR 45 mL/min/1.73m2), CKD stage 3b (eGFR 30 mL/min/1.73m2) and CKD stage 4+ (eGFR
