The nutritional status of patients with chronic obstructive pulmonary disease (COPD) is a significant factor that influences the prognosis of the disease. This observational study aimed to analyze the nutritional status of COPD patients and assess the associations between nutritional status, disease severity, and exercise capacity in four different regions of Croatia. In this multicenter study, 534 COPD patients were recruited and evaluated concerning fat-free mass (FFM), FFM index (FFMI), skeletal muscle mass index (SMMI), phase angle (PhA), pulmonary function tests, and the 6-minute walk test (6MWT). There were 325 (60.9%) male and 209 (39.1%) female patients with a mean age of 66.7±8.4 years. Most patients (73.2%) exhibited a moderate to severely abnormal obstructive pattern and had a reduced 6MWT distance (396.5±110.8 m). Among the participants, 32.8% were overweight and 22.3% were obese, and they had satisfactory values for nutritional status variables (FFM, FFMI, SMMI, PhA). There were no statistical differences between the centers in terms of nutritional status variables. There was a significantly positive correlation of forced expiratory volume in one second with body mass index (BMI) (r=0.148, p=0.001), PhA (r=0.256, p=0.00), FFM (r=0.365, p=0.00), and SMMI (r=0.238, p=0.00). However, there was no significant correlation of the 6MWT with BMI (r=-0.049, p=0.254), FFM (r=0.065, p=0.133), and SMMI (r=-0.007, p=0.867). The data analysis demonstrated that our patients were not underweight and that there was no significant difference between the centers in terms of BMI, FFM, FFMI, SMMI, and PhA. This lack of significant difference was observed even though one of the regions studied was Mediterranean.
