Introduction: Nutritional disturbances in patients with chronic obstructive pulmonary disease (COPD) are very common. Symptomatology and functionality in chronic diseases could be related with the nutrition. Malnutrition could aggravate the disease. Objectives: Therefore, the aims of this study were 1) to evaluate the profile of the patient with COPD and malnutrition, and 2) to determine the relationship between the nutritional status with functionality and symptomatology in COPD patients. Methods: An observational study was conducted in patients with severe COPD. The independence levels, quality of life was evaluated, comorbidities and anxiety and depression were evaluated. Respiratory function was assessed with spirometry, forced expiratory volume in 1 second (FEV1) was recorded, and Borg modified scale was used to determine de dyspnea perception. The Mini Nutritional Assessment questionnaire (MNA) evaluated the nutritional status. Finally, the simptomatology was assessed with Leicester Cough Questionnaire, and with London Chest Activity of Daily Living Scale. Results: A sample of 154 subjects was included in this study, 98 of them were males. A group of 71 subjects showed malnutrition and a group of 83 patients a normal nutritional status. The comparison between the groups showed significant differences in the clinical characteristics (p < 0.05). The analysis showed significant differences in dyspnea (p = 0.043), and the subscales of functionality related to respiratory symptoms self-care (p = 0.040) and leisure (p = 0.019) and the total score (p = 0.031). The worst results were shown in the patients with malnutrition. Conclusion: Our investigation shows that patients with COPD and malnutrition have worse results in symptomatology and functionality than patients with COPD without malnutrition.
