This study investigates sex-related differences of FEV1 decline in a real-life cohort.Methods: Prospective multi-centered study of COPD patients recruited between 2013 and 2022. Information collected at inclusion and visits: smoking status, symptoms, clinical characteristics, comorbidities. The evolution of FEV1 was analyzed in patients with 2 or more measures.Results: 3,228 patients were enrolled in the study. Women (36.5%) were younger, had lower BMI and were more current smokers than men patients (p<0.001). Regarding symptoms women had more dyspnea (p<0.009) and exacerbations (p<0.001). No sex differences were found for chest tightness and cough, except for more expectorations among men (p<0.004). For comorbidities men had more hypertension, ischemic heart disease, diabetes and less anxiety, depression, osteoporosis and asthma (p<0.001). Men had a lower predicted FEV1 (57.4%) than women (60.5%) (p<0.001) and a more severe COPD according to GOLD classification (p=0.005). No sex-related differences was observed for FEV1 decline.Conclusion: This study demonstrates differences on characteristics and some clinical aspects of women and men with COPD.FootnotesCite this article as Eur Respir J 2022; 60: Suppl. 66, 4514.This article was presented at the 2022 ERS International Congress, in session “-”.This is an ERS International Congress abstract.
