				        	Objective:To understand the smoking cessation behaviors in chronic obstructive pulmonary disease (COPD) patients aged 40 years or older in China and provide evidence for COPD control and prevention.Methods:COPD patients with post-bronchodilator FEV 1/FVC<70% were selected from COPD surveillance (2014-2015) of China, in which 5 791 current or former smokers defined by questionnaire survey were included in the study. The smoking cessation rate/ratio and the successful smoking cessation rate in COPD patients, the successful smoking cessation rate in COPD patients who ever smoked daily and the rate of attempting to quit smoking in current smokers with COPD were estimated using data adjusted by complicated sampling method. Results:The smoking cessation rate was 25.0% and the successful smoking cessation rate was 19.1% in COPD patients aged 40 years or older who ever smoked. The smoking cessation ratio was 23.1% and the successful smoking cessation ratio was 17.6% in COPD patients who ever smoked daily. The rate and ratio were higher in urban area than rural area ( P<0.05) and increased with age ( P<0.05). Patients who were aware of smoking being a risk factor for COPD had higher rate and ratio than patients who were not aware ( P<0.05). Patients with more severe airflow limitation and patients smoking less had higher rate and ratio ( P<0.05). Conclusions:The smoking cessation rate and ratio were low in COPD patients in China. More health education for COPD patients about smoking cessation needs to be strengthened. It is suggested for healthcare workers to actively advise smoking cessation and suggest smoking cessation ways for patients who smoke in their routine clinical service to increase the successful smoking cessation rate/ratio in COPD patients.
