China is the largest cigarette consuming country in the world. The emergence of electronic nicotine delivery systems (ENDS) in China may have important implications for the Chinese tobacco market. Unfortunately, research on ENDS in China, while growing, is still limited. This study was designed to examine the awareness and use of ENDS among adult urban residents in China. Data from five citywide representative surveys conducted in 2017-2018 were used. Percentages of residents who had ever heard of, ever used, or used ENDS in the past 30 days among all residents and smokers were estimated, in total and by demographic characteristics. Multiple logistic regression models were used to estimate the adjusted associations between awareness and use of ENDS and individual-level demographic characteristics and socioeconomic status (SES). Overall, 51.3% had ever heard, 4.8% ever used, and 0.9% used ENDS in the past 30 days. Men, young adults, those with high levels of education, and current smokers were more likely to be aware of and use ENDS. Among smokers, 67.8% had ever heard, 17.1% ever used, and 3.9% used ENDS in the past 30 days, respectively. Young adult smokers and smokers with high levels of education were more likely to be aware of and use ENDS. Our study results on ENDS awareness and use patterns and associated factors in China provide important evidence to inform research and policies related to ENDS manufacture, marketing, and sales in China.
中国是世界上最大的香烟消费国。电子烟在中国的出现可能对中国烟草市场产生重要影响。不幸的是，尽管中国对电子烟的研究在不断增加，但仍很有限。本研究旨在调查中国成年城市居民对电子烟的认知和使用情况。使用了 2017-2018 年进行的五次全市代表性调查的数据。估计了所有居民和吸烟者中，过去 30 天内听说过、曾经使用过或正在使用电子烟的居民的百分比，按人口统计学特征和社会经济状况（SES）进行了总计和分类。总体而言，51.3%的人听说过电子烟，4.8%的人曾经使用过电子烟，0.9%的人在过去 30 天内使用过电子烟。男性、年轻人、受教育程度较高者和当前吸烟者更有可能了解和使用电子烟。在吸烟者中，分别有 67.8%、17.1%和 3.9%的人听说过电子烟，曾经使用过电子烟，过去 30 天内使用过电子烟。年轻的成年吸烟者和受教育程度较高的吸烟者更有可能了解和使用电子烟。我们在中国关于电子烟认知和使用模式及相关因素的研究结果为中国电子烟制造、营销和销售相关的研究和政策提供了重要依据。
