Prevalence of self-reported chronic kidney disease in Brazil: National Health Survey of 2013

To describe the profile of adults who reported medical diagnosis of chronic kidney disease (CKD), according to selected variables. In a cross-sectional study with individuals included in the National Health Survey of 2013, a household population-based study was conducted in rural and urban areas of Brazil. A total of 60,202 individuals aged ≥ 18 years who self-reported a medical diagnosis of chronic renal failure or kidney disease were evaluated. Descriptive statistics, including calculations of prevalence and 95% confidence intervals (95%CI), were calculated. The prevalence of CKD was 1.4% (95%CI 1.3 - 1.6). It was similar between sexes: male, 1.4% (95%CI 1.1 - 1.6); and female, 1.5% ((95%CI 1.3 - 1.7). southern Brazil showed the highest frequency of this indicator (2.1%; 95%CI 1.6 - 2.7). The prevalence of dialysis among people with medical diagnosis of end stage renal disease was 7.4% (95%CI 4.4 - 10.3), being greater in males (12.4%; 95%CI 6.5 - 18.3). There was no difference between the age groups and schooling levels. CKD was referenced by 8.9% (95%CI 3.5 - 14.3) of the individuals with brown skin, with no difference among races/skin color. These results reveal various aspects of CKD in Brazil. The distribution of CKD was unequal, burdening especially individuals with poor education, demanding greater investments in health programs for the confrontation of CKD. Thus, these data allow the planning of public policies aimed at the prevention of this disease and health promotion.
