OBJECTIVE: To evaluate the nutritional status of patients with chronic obstructive pulmonary disease (COPD) and to investigate the association between nutrition and pulmonary function in these patients. PATIENTS AND METHODS: We selected 210 patients with COPD (148 men and 62 women) who were divided into three groups of 70 patients depending on severity of disease: mild, moderate or severe. The association between nutritional status and pulmonary function was studied by measuring body mass index (BMI), forced expiratory volume in the first second (FEV1), and the FEV1/forced vital capacity (FVC) ratio. RESULTS: Patient age ranged from 41 to 91 years (mean 65.7 ± 9.4 years). Means of BMI in the groups with mild, moderate and severe COPD were, respectively, 24.7, 25.1 and 23.7 kg/m2 (P = 0.1). Most patients (70.5%) had BMI between 20 and 29.9 kg/m2. Among the patients with BMI < 20 kg/m2 , 24.3% had mild COPD, 43.2% had moderate COPD, and 32.4% had severe COPD. The correlation coefficient between BMI and FEV1 was 0.15, and between BMI and FEV1 /FVC, 0.22. CONCLUSION: There was no association between nutritional status and decreased pulmonary function in our study
