Abstract:
Objective:To describe the current status of smoking among Chinese people aged 15 and above and analyze its epidemic evolution.Methods:A stratified multi-phased randomized cluster sampling design of the Global Adult Tobacco Survey was used. The cross-sectional survey was conducted from July to December 2018, covering 200 districts/counties in 31 provinces of China. Field data was collected through in-house face-to-face interviews by trained investigators using a tablet computer. 19 376 individual questionnaires were completed, with an overall response rate of 91.50%. The data were weighted for complex sampling and analyzed with SAS 9.4.Results:In 2018, the current smoking prevalence of adults aged 15 and above was 26.59%, with that higher among males (50.47%) than among females (2.07%) and higher among those in rural (28.87%) than among those in urban areas (25.05%). The quitting rate was 20.10%, with a higher rate among females (30.22%) than males (19.64%). However, there was no significant difference between rural and urban areas ( P=0.864). Compared with the previous data, the smoking rate tends to drop, with a substantial decrease among the 25-44 age groups and 45-64 age groups. The most significant decline occurs among those with higher education (Junior college and above). In addition, in 2018, current daily smokers aged 15 and above in China started to smoke daily at an average age of 20.95 years old. For current smokers, 16.00 cigarettes were consumed each day on average. Conclusion:Although the current smoking prevalence among the Chinese population aged 15 and above tends to decrease, the decreasing speed is too slow to achieve the target set in the Healthy China Action (2019-2030). Consequently, much more effective efforts to control tobacco need to be enforced.
