Chronic Kidney Disease and Associated Risk Factors in Isolated African-Brazilians Communities: Data from Prevrenal Study

Background: The prevalence of chronic kidney disease (CKD) in the early stages is unknown. Clinical conditions associated with this loss of renal function, including systemic hypertension, diabetes, anemia, dyslipidemia, metabolic syndrome, and cardiovascular risk are also poorly studied. Data from the PREVRENAL study are intended to provide new information on the development and progression of CKD in a specific population group. Main body: In 32 isolated communities of African slave descendants, 1, 539 people were evaluated. The study was conducted in three phases: in the first stage, a clinical, nutritional and anthropometric evaluation was performed; measurements of serum and urinary markers were provided; and exams related to other comorbidities were performed. The second stage consisted of repeated examinations in individuals diagnosed with CKD, systemic arterial hypertension and / or diabetes mellitus; patient selection for imaging exams was performed; and the cardiac risk is calculated. Long-term monitoring of all individuals will be the last phase of the study. The dataset deposited here describes the results of the first and second stages. Conclusion: Thus, we hope that the data set can improve the knowledge about the onset and progression of CKD, as well as the associated risk factors, mainly applied to the population of African descent.
