Our objective was to evaluate the association between self-reported color-race, genomic ancestry, and the presence of chronic kidney disease (CKD), assessed by glomerular filtration rate and albuminuria in patients with type 1 diabetes.Methods: This is a multicenter, observational, cross-sectional study with 1564 patients, conducted between August 2011 and August 2014 in 14 public clinics from 10 Brazilian cities. The ethnic aspects of the patients were evaluated using self-reported color-race and genomic ancestry (divided in European, African, and Amerindian). We divided the patients into groups: normal renal function and CKD.Results: More patients self-declared themselves as black and brown in the group with CKD. The multivariate logistic analysis revealed that self-reported color-race was not associated with CKD and that a higher African ancestry was also not associated with CKD (p=0.06). Patients with an African ancestry of 50% or higher had [...]
