DESCRIPTION OF THE SUBJECTIVE GLOBAL ASSESSMENT COMPONENTS IN NONDIALYSIS-DEPENDENT CHRONIC KIDNEY DISEASE PATIENTS

Abstract

Subjective Global Assessment (SGA) is a well-recognized and valid tool for diagnosing malnutrition in chronic kidney disease (CKD). SGA is based on components as weight change, dietary intake change, gastrointestinal symptoms, functional capacity, comorbidities related to nutritional condition and physical examination. Herein, we aimed at investigating which SGA alteration was the most prevalent in patients in the nondialysis stages of CKD. Seven-hundred and three patients were studied (91% CKD stages III and IV, eGFR 34.1±13.7 mL/min, 64±13.3 years, 58% men, 45% diabetics, BMI 27.9±7.4 kg/m2). Each of the SGA components was scored from 1 to 7 according to the severity, and values ≤ 5 were considered as abnormal. Malnutrition was observed in 11.5% of the patients, of which 10.5% mild to moderately malnourished (score of 3–5) and 0.7% severely malnourished (score of 1 or 2). The frequency of alterations in the SGA components is demonstrated below: As can be seen dietary intake change was the most frequent alteration among the SGA components in nondialysis CKD patients.fx1
