[One year after the implementation of 2015 Tobacco Control Regulation on persons aged 15 years and over tobacco use in Beijing].

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. 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, . 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 29.5were 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. 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.
