e cigarette electronicrol and Prevention and Beijing Normal University. The study reported on the e-cigarette use rate and related factors in the past 30 days among adults over 18 years old in China from 2015-16 to 2018-19. This study reports for the first time the current status and changing trends of adult e-cigarette use in China in recent years, and provides baseline data for the evaluation of China's e-cigarette sales restriction policy." />
The characteristics of Chinese e-cigarette users are different from those of developed countries. Studies have shown that among 18-29 year-olds, urban residents, people with middle school education and above, people with higher annual incomes, factory or construction handicraft workers, and obese people, the use of e-cigarettes is higher. In contrast with developed countries such as Sweden and the United States, Chinese people with higher education or higher income levels are more likely to use e-cigarettes. This means that the public still lacks understanding of the health hazards of nicotine or e-cigarettes. In addition, from 2015 to 2019, people with lower household income levels increased the use of e-cigarettes, which may exacerbate health inequality. (Figure 2)
China's adult e-cigarette use rate has increased significantly from 2015 to 2019
Data represent weighted estimates from the China Chronic Disease and Nutrition Survey 2015 (n=189 306) and 2018 (n=184 475). Populations for the years 2015鈥?6 and 2018鈥?9 were standardised with the 2010 population census to gain comparable estimates. Error bars show 95% CIs. The unweighted denominators were much greater than 50 for all subgroups apart from current female smokers aged 18鈥?9 years; in this subgroup, the unweighted denominator was 61 in 2015鈥?6 and 50 in 2018鈥?9, and these results should be interpreted with caution. Among the total population, awareness of e-cigarettes significantly increased in 2018鈥?9 compared with 2015 鈥?6 (p<0路0001). p values 鈥嬧€媋re shown in appendix 2 (p 12).
