Objective: The general aim of IBERICAN study is to know the prevalence and incidence of cardiovascular risk factors and cardiovascular and renal disease in Spain. The aim of this abstract is to know the prevalence of chronic kidney disease according to the time of evolution of diabetes. Design and method: The IBERICAN Study is a longitudinal, observational, and multicentric study with subjects between 18 to 85 years of age, recruited in Primary Care (PC) and who will be followed up at least 5 years. The final sample size is estimated in 7,000 patients. We show the baseline characteristics of the patients in the first visit (n = 3,042). The glomerular filtrate was estimated by CKD-EPI equation, and the evolution time of diabetes was classified into three categories (<5 years, 5–10 years y >10 years) that divided the sample into 34,1%, 31,4% y 34,5% of the patients. Results: The prevalence of diabetes was 19% (n = 572) and the mean evolution time was 9.1 ± 6.2 years. In diabetics with more time of evolution, the nephropathy was more frequent (55.6% vs 28.9% vs 15.6%, p = 0.009). Chronic kidney disease was more prevalent in patients with more evolution time of diabetes (22.6% vs 14.0% vs 8.8%, p = 0.002). Also, the presence of glomerular filtrate <60 ml / min (11.2% vs 6.4% vs 6.4%, p = 0.043) and the simultaneous lesion of GF <60 ml / min associated with albuminuria (10.1% vs 5, 8% vs 1.8%, p = 0.043) was higher in patients with more evolution time of diabetes. Conclusions: The diabetic patients with more evolution time of the disease, presented a higher prevalence of all forms of renal injury.
