Mortality trend due to chronic kidney disease in Brazil: an ecological study.

Abstract

To analyze chronic kidney disease mortality in Brazil according to sex, age group and region of residence, from 2009 to 2020. This was a time series study having deaths as its unit of analysis, based on Mortality Information System data. The mortality rate was standardized using the direct method and the temporal trend was analyzed using the Prais-Winsten method. There was a rising trend in chronic kidney disease mortality, ranging from 2.82, in 2009, to 3.24 in 2020 (average annual increase 1.29%; 95%CI 0.73;1.85), with a greater increase in males (1.14% per year; 95%CI 0.52;1.76), those aged 75 years and over (2.23% per year; 95%CI 1.87; 2.60) and in the Northern Region (3.86% per year; 95%CI 1.86;5.90) and Northeast Region (3.36% per year; 95%CI 2.24;4.50). Chronic kidney disease mortality showed a rising trend in the period, with sociodemographic disparities. A rising mortality trend was found for both sexes, with a greater increase in males, those aged over 75 years and in the North and Northeast regions of Brazil; mortality was highest in the Midwest region throughout the entire period. The results point to the need to implement public policies with guidelines for addressing chronic kidney disease, focused on strengthening Primary Health Care (PHC). Expanding access to health services, health education and integration between PHC, health surveillance and specialized care are strategies that would possibly prove to be efficient in managing this chronic health condition.
