To explore the clinical characteristics of female patients with chronic obstructive pulmonary disease(COPD).

A total of three hundred and sixty-six inpatients were confirmed COPD were divided into two groups according to sex: male and female, we analyzed the characteristics of patients whose age, history of disease, tobacco exposure rate and time of tobacco exposure, the distribution of pulmonary dysfunction, the distribution of disease assessment groups, and the duration of hospitalization, hospital mortality with COPD.And its differences with male patients with COPD.Analysed the relationship between years of tobacco exposure and severity of pulmonary dysfunction in female patients with COPD.Analysed the clinical status of female patients with COPD and the relationship between the number of years of tobacco exposure and the distribution of clinical assessment groups.

Of the 366 patients, 126 were female (34.4%), 116 had a long history of tobacco exposure (92.6%). The duration of tobacco exposure was positively correlated with the severity of pulmonary dysfunction in women with COPD.The longer the tobacco exposure, the more severe the pulmonary dysfunction (χ²=24.987, P<0.01). There was no significant difference between the number of years of tobacco exposure and the distribution of disease assessment groups in female patients with COPD (χ²=11.164, P=0.083), but the distribution of tobacco exposure in groups B and D were significantly higher than that in groups A and C, and the difference was significant (χ²=9.063, P<0.01). Compared with male patients, there were no significant differences in age, history of disease, tobacco exposure rate, time of tobacco exposure, distribution of pulmonary dysfunction, distribution of disease assessment groups and hospital mortality (allP>0.05).

The female patients with COPD whose smoking rate is low, the exposure rate of secondhand smoke is high, the total rate of tobacco exposure is similar to that of male patients, and the degree of pulmonary dysfunction is positively correlated with the time of tobacco exposure.In group B and group D, there are no significant difference in the degree of pulmonary dysfunction, the evaluation of clinical condition, the course of treatment and the outcome of treatment.
