Anemia is a frequent complication in chronic kidney disease (CKD), and is frequently associated with symptoms such as physical disability, decreased neurocognitive function, and poor quality of life. Our objective is to know the prevalence and severity of anemia between stages of CKD in patients who attended a nephrology clinic for the first time.


Transversal, descriptive, observational study. Records of adult patients who attended an outpatient nephrology clinic in the period from February 2019 to February 2020 were included. Anemia staging was performed according to the world health organization. Descriptive statistics were performed, with a 95% CI and a p-value ≤0.05.


1568 patient records were included. Mean age was 56.01 ± 16 years and 51% (804) were women. Distribution of patients by CKD stage: 9% stage 1, 11% stage 2, 12% stage 3a, 18% stage 3b, 23% stage 4, and 27% stage 5. 12% were undergoing renal replacement therapy. 53% of the population had anemia at the cut-off point of Hb<13 for men and <12 for women; stratification of anemia severity between stages of CKD is presented in figure 1. The main comorbidities and risk factors in the subjects with anemia were type 2 diabetes mellitus and hypertension (55%), proteinuria (38%), hypoalbuminemia (34%), hyperkalemia (37%) overweight or obesity (58%), hyperglycemia (45%) hypertriglyceridemia (35%) and hypercholesterolemia (31%).


In patients who attended for the first time an outpatient nephrology clinic, a high prevalence of anemia was found in CKD patients, being more frequent and more severe from stage 3b to stage 5. Identifying these findings will allow establishing public health policies and models of care for patients with CKD.
