Investigation of the Relationship Between Disease Severity and Nutritional Status in Male Outpatients With COPD Through Subjective Global Assessment

Abstract

We aimed to investigate the relationship between disease severity and nutrition status through subjective global assessment (SGA) in men with chronic obstructive pulmonary disease (COPD). A total of 80 stable male subjects with COPD (20 in each group) were included in the study according to the Global Initiative for Chronic Obstructive Lung Disease 2011 classification (A, B, C, and D). Nutritional assessment was performed using SGA as the gold standard. It was determined that 55.6% of the patients with severe malnutrition were in group D. SGA appears to represent a useful method for identifying ambulatory patients in need of comprehensive nutrition assessment and support.
