Applicability of subjective global assessment and malnutrition inflammation score in the assessment of nutritional status on chronic kidney disease.

Up to now, there is no single method that provides complete and unambiguous assessment of the nutritional status in chronic kidney disease (CKD). Therefore, it has been recommended the use of many nutritional markers. The subjective global assessment (SGA) contains questions regarding the clinical history and physical examination. Subsequently, other versions of the SGA were developed. The malnutrition inflammation score (MIS) was also developed from the original version of the SGA and consists of 70% of the items common to SGA in addition to objective questions. Since many modifications were proposed in the original form of SGA, the use of these questionnaires in CKD patients has increased substantially in clinical practice. Therefore, this paper aims to review the applicability of the SGA and MIS when applied to assess the nutritional status of CKD patients.
