Modified quantitative subjective global assessment of nutrition in patients on the renal transplant waiting list.

摘要

Subjective global assessment (SGA) of nutritional status is a widely used and validated method for identifying and classifying malnutrition. It has been thought that this semiquantitative feature restricts the reliability and precision of the SGA. Recently, in an effort to assess nutritional status, a modified quantitative SGA system has been devised in which scores are assigned for items or components of the SGA. This prospective study evaluated the correlation of the quantitative SGA with objective nutritional parameters and compared this method with conventional SGA in a group of patients on the renal transplant waiting list.
