SEX-SPECIFIC DIFFERENCES IN A LARGE COHORT OF BRAZILIAN INCIDENT DIALYSIS PATIENTS OVER 12 YEARS: A RETROSPECTIVE STUDY.

Introdução

Sex-specific differences have been reported in the epidemiology of all stages of chronic kidney disease worldwide, but national data are lacking. We aimed to compare the demographical, clinical, and dialysis characteristics of incident dialysis men and women in a large cohort of Brazilian patients over 12 years.

Material e Método

Retrospective cohort study, multicentric coordinated by Brazilian Society of Nephrology. We enrolled all adult incident dialysis patients included in the Brazilian Dialysis Registry from January 2011 to December 2022. Studied variables included age, skin color, education, CKD etiology, predialysis nephrologist care, dialysis characteristics, and geographic region. We also analyzed the sample in each of three 4-year periods over the 12 years of data collection.

Resultados

A total of 24,632 incident dialysis patients were included. The prevalence of men was 59.1% and remained stable over the three 4-year periods. Women started dialysis younger (58.5±16.2 vs. 59.5±14.4 years; p<0.001), had a lower educational level, more predialysis nephrologist care, and a higher prevalence of peritoneal dialysis. Most of these differences had a low degree of variation during the 4-year periods.

Discussão e Conclusões

We found a consistently higher prevalence of men on dialysis and differences in demographical, clinical, and dialysis characteristics revealing inequalities in the management of their treatment.
