[Prevalence of chronic kidney disease in France, Esteban study 2014-2016]

The epidemiology of chronic kidney disease remains poorly described in France despite its burden. The objective of our study was to provide an estimate of the prevalence of chronic kidney disease stades 3-5 (without replacement therapy) in France.

The data come from the Esteban study carried out in France between 2014 and 2016 on a representative sample of the French population. This study included 3,021 adults between 18 and 74 years old. Of these, 2422 adults (80.2%) had serum creatinine assay and were included in this analysis. Renal function was estimated by calculating glomerular filtration rate using the Chronic kidney disease epidemiology collaboration (CKD-Epi) and European Kidney function consortium (EKFC) equations.

The means glomerular filtration rate in our population were respectively 97.5 and 89.0 mL/min/1.73 m² with the CKD-EPI and EKFC equations. The prevalence of chronic renal failure, defined by a glomerular filtration rate less than 60 mL/min/1.73 m² was 1.5% with the CKD-EPI formula and 2.1% with the EKFC formula in adults aged 18 to 74 years. The prevalence was higher in women than in men and increased with age, reaching 6.5% and 9.9% in 65-74 years with the CKD-EPI and EKFC equations, respectively. After extrapolation to the French population, the number of adults with chronic kidney disease stades 3-5 without renal replacement therapy was around 1.6 million.

In France, the prevalence of chronic kidney disease stades 3-5 without renal replacement therapy was between 1.5 and 2.1% of the adult population aged 18 to 74.
