Subjective global assessment of nutritional status: further validation.

Author information

  • 1INTA, University of Chile, Santiago.


Subject global assessment of nutritional status was performed on 175 patients admitted to the medical-surgical gastroenterology service of a general hospital by a first-year resident and a specialist in clinical nutrition who were not aware of each other's evaluation. Patients were classified as well nourished or moderately or severely undernourished. Simultaneously, anthropometry was performed, serum albumin measured, and two units of PPD inoculated. A 79% concordance between the global subjective assessments made by the residents and the specialists was found. Patients in the three groups had significantly different weight, midarm circumference, triceps skinfold, and serum albumin values, whereas the total lymphocyte count and the percentage of negative PPD reactions were not significantly different. Subjective global assessment is a useful tool for the evaluation of nutritional status, even when used by inexperienced professionals.
