[Quit intention and smoking cessation behavior of current smokers aged 15 years and above in China, 2018].

ABSTRACT

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.
