Abstract: Objective To analyze the prevalence of smoking cessation and factors associated with intention to quit smoking among adult smokers in Qingdao city, and to explore the direction for policy planning. Methods A total of 5 000 residents aged ≥ 15 years were selected in Qingdao through multiple stages sampling to conduct a household face-to-face interview. Indicators as quit proportion in ever smokers, frequency of quit attempts, percentage of smokers who received health care provider advice were calculated to describe the prevalence of smoking cessation by weight on age proportions from the 2010 census. Methods of univariate and multiple Logistic regression in complex sample were used to explore factors associated with intention to quit smoking. Results There were 20.2% of ever smokers who had quit smoking. 13.5% of current smokers planed or thought about quitting within the next 12 months. During the past 12 months, 24.8% of current smokers had attempted to quit smoking and among those, 54.6% had tried two or more times. 66.8% of smokers who visited a health care provider received cessation advice. After controlling for other factors, just as showed in multiple analysis, we found that the intention to quit smoking was significantly associated with the smoking-related health knowledge and a quit history. Conclusions The percentage of smokers who had tried to quit smoking was lower. The smoking cessation services should be provided more professionally and accessibly to encourage smoking cessation. Some targeted propaganda strategies should be made to improve the willingness of cessation.
