AbstractObjective: To understand the current status of smoking and smoking cessation in persons aged 15 years and over in Beijing and evaluate the effect of 2015 Beijing Tobacco Control Regulation. Methods: In 2014 and 2016, based on the principles and methodology of the Global Adult Tobacco Survey. A total of 50 communities or townships were selected from 324 communities or townships in Beijing through multistage cluster sampling, and 2 community (village) committees from each community or township were selected with the method of probability proportional to size (PPS). A total of 100 surveillance sites were set, and 100 households were selected from each surveillance site by using simple random sampling. Data were collected through face-to-face interview from the eligible family members aged 15 years and over with the assistance of a tablet computer. Statistical analyses were conducted by using complex sampling analyses module of SPSS 20.0, with weights as a combination of sampling weights, non-response weights and post- stratification weights, for the calculation of current smoking prevalence, daily smoking prevalence, smoking cessation rate, etc. Results: A total of 8 484 and 9 372 valid questionnaires were obtained, respectively, in 2014 and 2016, with the response rate of 86.5% and 96.5%. The current smoking prevalence in persons aged 15 years and over was 23.4% in 2014, and 22.3% in 2016. According to the 6(th) national census data, the current smoking population decreased by 199 000 in Beijing. The proportion of daily smokers declined from 20.7% in 2014 to 19.2% in 2016. The daily number of cigarettes consumed by current smokers increased from 14.6 in 2014 to 15.4 in 2016. The smoking cessation rate was 14.9% in 2014 and 16.8% in 2016. The proportion of current smokers who had at least one smoking cessation attempt in the past 12 months increased from 22.3% in 2014 to 23.2% in 2016, and the proportion of current smokers who planned to quit smoking increased from 11.6% to 15.5%. Among the current smokers who had visited doctors in the past 12 months, the proportion of those having smoking cessation advice was 58.9% in 2014 and 59.2% in 2016. In 2016, among the current smokers who had attempted to quit in the past 12 months, 36.8% were aware of the smoking cessation clinics, and 29.5%were aware of the quitline. Among those who were aware, only 7.7% had actually visited the cessation clinics, and 5.5% had used the quitline. Conclusions: After the implementation of 2015 Beijing Tobacco Control Regulation for 1 year, the current smoking prevalence in persons aged 15 years and over showed decreasing. It is necessary to further prompt the expansion of smoking cessation service to cover more current smokers.
