RESUMEN
There is a paucity of data on malnutrition in different socioeconomic status in chronic kidney disease (CKD) patients. Hence, this cross-sectional study was undertaken in CKD-ND and CKD-D. The aim of the study was to assess the prevalence of malnutrition in the various stages of CKD among the various socioeconomic groups, namely the low-income groups and the upper-middle-income groups. This is a cross-sectional study conducted among 394 patients. The patient data were obtained from three institutions: Institution 1, Institution 2, and Institution 3. Patients were predominantly from the South Indian population and were between the age groups of 18 and 80 years. Measurements: malnutrition was assessed using anthropometry, body composition monitor, biochemical parameters, and dietary recall. Subjective Global Assessment Scale for nondialyzed patients and Malnutrition-Inflammation Score for dialyzed patients were also collected . As per the CKD stages, we found the percentage of malnutrition to be 7% in Stage III, 14% in Stage IV, 18% in Stage V, and 68% in Stage V-D in the upper-middle-income group, whereas it was 10% in Stage III, 26% in Stage IV, 40% in Stage V, and 93% in Stage V-D in the low-income group. The severity of malnutrition was stratified according to the stages of CKD, and it was found to be higher in progressive stages of CKD among the low-income groups as compared to the high-income groups.
