We hypothesized that social deprivation is a major driver of these spatial variations, independent of healthcare access and clinical risk factors, and that its contribution is stable over time.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We conducted an ecological study including 102\u2009226 incident ESKD cases across 34\u2009830 municipalities in metropolitan France from 2012 to 2021, using data from the national REIN (Renal Epidemiology and Information Network) registry. A Bayesian hierarchical spatiotemporal model was used to estimate the association between ESKD incidence and ecological-level covariates: social deprivation [measured by the French European Deprivation Index (EDI)], diabetes prevalence, dialysis center accessibility and long-term exposure to PM2.5 (fine particulate matter, \u22642.5 \u00b5m in diameter). We estimated the population-attributable fraction of ESKD incidence for each factor under various counterfactual scenarios.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Social deprivation was strongly associated with ESKD incidence [relative risk per 1 standard deviation increase in EDI: 1.10 (95% credible interval 1.09\u20131.11)] and explained 34.7% of its spatial variability. The association was only partially mediated by diabetes prevalence [mediation proportion: 15.3% (95% confidence interval 12.5\u201318.2)]. The model incorporating all covariates explained 49.9% of the observed spatial heterogeneity. The effect of social deprivation remained consistent over time. Reducing deprivation in the most disadvantaged areas to the levels of the 5th, 25th and 50th percentiles of less deprived areas could have prevented an estimated 23\u2009092, 17\u2009450 and 13\u2009601 ESKD cases, respectively, over the study period.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Social deprivation is the leading ecological determinant of spatial disparities in ESKD incidence in France, with limited mediation by clinical factors and persistent effects despite universal healthcare.
