    AbstractThe prevalence of chronic obstructive pulmonary disease (COPD) is increasing worldwide, with the fourth highest mortality rate. This study aims to analyze pulmonary function, physical activity, and quality of life (QoL) between genders from the perspective of pulmonary rehabilitation in Korean patients with COPD. This study investigated raw data from the Korea National Health and Nutrition Examination Survey from 2015 to 2019 and included 151 COPD patients (men: 66.55 ± 10.07 years, women: 65.21 ± 11.73) out of 39,759 participants. Pulmonary function, such as forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1), and frequency of physical activities (e.g., physical activity for work and leisure, strengthening exercise, and sitting time a day) and QoL by using EQ-5D-3L, were compared between genders in patients with COPD. Smoking status differed in health-related characteristics between genders (P < .001). In pulmonary function, the FVC (men: 3.48 ± 0.98ℓ, women: 2.53 ± 0.56ℓ, P < .05), FEV1 (men: 2.13 ± 0.93 ℓ, women: 1.88 ± 0.53 ℓ, P < .001), FEV6 (men: 3.16 ± 1.00ℓ, women: 2.46 ± 1.56ℓ, P < .001) and peak expiratory flow (men: 5.61 ± 2.44ℓ/s, women: 4.68 ± 1.53ℓ/s, P < .05) was higher in men, however, predicted FEV1 (men: 66.03% ± 23.13%, women: 79.95% ± 18.45%, P < .05) and predicted FEV1/FVC ratio (men: 59.67% ± 15.02%, women: 74.10% ± 10.49%, P < .001) in women. The frequency of strengthening exercise was higher in men (P < .05). QoL of patients with COPD was not significantly different between genders. To provide correct interventions and pulmonary rehabilitation to patients with COPD, gender differences, including physiological and psychological differences, must be considered.Copyright © 2022 the Author(s).
