Objective: To describe the current situation on quit intention and quit attempts among current smokers aged 15 years and above in China and explore the main factors affecting their smoking cessation behaviors. Methods: The subjects were people aged 15 years and above in China. A stratified multi-phased randomized cluster sampling method was used. The survey covered 200 districts/counties in 31 provinces (autonomous regions and municipalities directly under the central government), including 19 376 people under investigation. The data were weighted with SAS 9.4 for complex sampling analysis, and the frequency and weighted component ratio were used for description. The influencing factors were studied using the Rao Scott χ2 test and unconditional multivariate logistic regression. Results: Among current smokers, 6.63% reported that they planned to quit smoking in the next month, 5.44% for men and 8.49% for women. 17.96% of the current smokers made quit attempts in the past 12 months, with 17.80% men and 22.15% women. People who smoke occasionally (OR=3.42, 95%CI: 2.09-5.59) made quit attempts in the past (OR=4.91, 95%CI: 0.33-0.52) and knew that smoking would lead to three diseases (OR=2.24, 95%CI: 1.48-3.40) had higher quit intention. People who occasionally smoke (OR=1.68, 95%CI: 1.20-2.34) received smoking cessation suggestions from medical staff (OR=1.96, 95%CI: 1.62-2.37), were a ware of that smoking causes three diseases (OR=1.63, 95%CI: 1.32-2.02) and had smoking prohibition regulations in indoor areas of their homes, had a higher rate of quit attempts. Conclusion: Providing effective smoking cessation intervention services and creating a supportive tobacco control environment are significant in promoting smoking cessation behavior.
目的： 描述我国≥15岁现在吸烟者戒烟意愿及尝试戒烟行为，探讨影响其戒烟行为的主要因素。 方法： 研究对象为我国≥15岁现在吸烟者。采用多阶段分层整群随机抽样，在全国31个省（自治区、直辖市）共抽取200个监测点，最终完成调查19 376人。数据加权后，使用SAS 9.4软件复杂抽样设计方法进行分析，采用频数和加权构成比进行描述，使用Rao-Scott χ2检验和非条件多因素logistic回归进行影响因素分析。 结果： 6.63%的现在吸烟者准备在1个月内戒烟，男性为5.44%，女性为8.49%。17.96%的现在吸烟者在过去12个月尝试过戒烟，男性为17.80%，女性为22.15%。多因素分析结果显示，偶尔吸烟（OR=3.42，95%CI：2.09~5.59）、尝试过戒烟（OR=4.91，95%CI：0.33~0.52）以及知晓吸烟导致3种疾病（OR=2.24，95%CI：1.48~3.40），戒烟意愿较高。偶尔吸烟（OR=1.68，95%CI：1.20~2.34）、接受过医务人员的戒烟建议（OR=1.96，95%CI：1.62~2.37）、知晓吸烟导致3种疾病（OR=1.63，95%CI：1.32~2.02），尝试戒烟率较高。 结论： 提供有效的戒烟干预服务以及创建控烟支持性环境对促进戒烟行为具有重要意义。.
