ABSTRACT
Objective:
To evaluate the clinical differences between smokers and non-smokers with chronic obstructive pulmonary disease (COPD).Methods:
The clinical data of 5 183 COPD patients, including 3 688 smoking COPD patients and 1 495 non-smoking patients, were collected from the respiratory and critical medicine clinics of 12 Grade-A hospitals in Hunan Province and Guangxi Zhuang Autonomous Prefecture from December 2016 to December 2019. The general condition, clinical symptoms, acute exacerbation history and pulmonary function of the two groups were compared.Results:
⑴ Non-smokers were more likely to be female, to be younger and had a lower educational level ( P<0.05). There was no difference of body mass index (BMI) and marriage statue between two groups ( P>0.05). ⑵ Clinical features the incidence of chest distress in non-smoking COPD patients was higher than that in smoking COPD patients (86.8% and 81.4%, respectively), and the incidence of asthma was also higher than that of smoking COPD patients (86.0% and 83.1%, respectively), with statistically significant difference ( P<0.05). There was no significant difference in the incidence of cough and expectoration between the two groups ( P>0.05). The COPD assessment test (CAT) score of non-smoking COPD patients was significantly higher than that of smoking group (16.2±6.4) and (15.7± 6.5) ( P<0.05). There was no significant difference in the score of dyspnea modified medical research council dyspnea scale (mMRC) and the risk of acute exacerbation between the two groups ( P>0.05). The first second exertional volume as a percentage of predicted value (FEV 1%) and forced vital capacity (FVC) of non-smoking COPD patients were higher than those of smoking COPD patients ( P<0.05).Conclusions:
Compared to smokers with COPD, non-smokers more are more likely to be female and have more severe clinical symptoms.
