PREVALÊNCIA DE DOENÇA RENAL CRÔNICA E FATORES ASSOCIADOS EM PESSOAS COM ≥ 50 ANOS NO BRASIL: ESTUDO ELSI-BRASIL

Abstract

Chronic Kidney Disease (CKD) is characterized by being a kidney injury that leads to the progressive and irreversible loss of kidney function, so when we use the term CKD we are referring to a certain group of diseases that exclusively affects kidney function. The aim of this study was to investigate the prevalence of self-reported chronic kidney disease and associated factors in the elderly population of Brazil. This cross-sectional study used baseline data from the Brazilian Longitudinal Study of the Health of the Elderly (ELSI-Brazil), conducted between 2015 and 2016, covering a cohort of individuals aged 50 to 80 years or older, living in 70 municipalities in the five main regions of Brazil. The sample consisted of 9,421 participants, who answered a questionnaire, with emphasis on the main question about the presence of chronic renal failure diagnosed by physicians. It was possible to observe a high prevalence of CKD among the participants with no differences between the sexes. In addition, factors such as poor self-rated health and the presence of high blood pressure have been shown to be very susceptible to the disease. Thus, a health intervention directed to vulnerable groups is necessary, since early diagnosis represents an effective way to mitigate morbidity and mortality.
