To understand the awareness, current or past behavior on electronic cigarette smoking (ECS) and associated factors, among adults aged ≥15 years old in Shandong province. Relationship between ECS and cessation of smoking was also studied. Using the global standard questionnaire, a cross-sectional survey was conducted among 6 401 adults selected by stratified multi-stage cluster sample method. Electronic data was collected by handheld computer. Data were weighted and analyzed by SPSS 19.0 complex program. The prevalence rates of awareness, ever or current smoking of e-cigarettes appeared as 37.6, 3.8 and 0.6 respectively. Data from logistic regression analysis showed that risk factors for ECS were living in urban area, at younger age, being current or former cigarettes smoker and with knowledge on the risks of smoking or being encouraged to stop smoking. Among the electronic cigarettes smokers, those who tried to quit smoking (30.1) had a significantly higher rate than that of the non-smokers (19.5) (<0.05), however, the successful quitting rate was much lower than that in the non-ECS users (<0.05). Rates on the awareness and uptake of electronic cigarettes are on the rise. It is necessary to strengthen and standardize the monitoring programs to provide evidence for setting up targeting intervention strategies.
为了解山东省15岁及以上成年人对电子烟吸食的知晓情况、当前或过去的行为及相关因素。同时研究电子烟与戒烟之间的关系。采用全球标准问卷，通过分层多阶段整群抽样方法对6401名成年人进行横断面调查。利用手持计算机收集电子数据。数据经加权处理后，采用SPSS 19.0复杂程序进行分析。电子烟知晓率、曾经或当前吸食率分别为37.6%、3.8%和0.6%。逻辑回归分析数据显示，电子烟吸食的危险因素包括居住在城市地区、年龄较小、当前或曾经吸烟以及知晓吸烟风险或受到鼓励戒烟。在电子烟吸食者中，尝试戒烟的比例（30.1%）显著高于非吸食者（19.5%）（P<0.05），然而，成功戒烟率远低于非电子烟使用者（P<0.05）。电子烟的知晓率和使用率呈上升趋势。有必要加强和规范监测项目，为制定针对性干预策略提供依据。
