OBJECTIVES:This study investigated the prevalence and correlates of electronic cigarettes (e-cigarettes) use in Taiwan. DESIGN AND SETTING:We studied a nationally representative random sample in the 2015 Taiwan Adult Smoking Behavior Survey. PARTICIPANTS:This study included 26 021 participants aged 15 years or older (51% women, 79% non-smokers, 16% aged 15-24 years), after excluding 31 persons (0.1%) who had missing information on e-cigarette use. PRIMARY OUTCOME MEASURES:The prevalence of ever having used e-cigarettes was calculated in the overall sample and by smoking status (current, former and never) or age (15-24, 25-44 and ≥45 years). We performed multivariable log-binomial regression to assess correlates of ever having used e-cigarettes among all participants and separately for subgroups by smoking status and age. RESULTS:Approximately 3% of all participants had ever used e-cigarettes. The prevalence of ever having used e-cigarettes was high in current smokers (14%) and people aged 18-24 years (7%). E-cigarette use was particularly common in people aged 15-24 years who were current (49-52%) or former (22-39%) smokers. Ever having used e-cigarettes was positively associated with tobacco smoking (adjusted prevalence ratio (aPR): 21.5, 95% CI 15.4 to 29.8, current smokers; aPR: 8.3, 95% CI 15.2 to 13.1, former smokers), younger age and high socioeconomic status. Age remained a significant factor of ever having used e-cigarettes across smoking status groups. Among non-smokers, men had a 2.4-fold (95% CI 1.5 to 3.8) greater prevalence of e-cigarette use than women. CONCLUSIONS:E-cigarette use was uncommon in the general population in Taiwan, but prevalence was high among smokers and young people. This study highlights challenges that e-cigarettes pose to tobacco control, which warrant high priority action by policymakers and public health professionals. E-cigarette regulations should focus on young people.

目的:本研究调查了台湾使用电子烟(电子烟)的普遍性和相关性。
设计与地点:我们在2015年台湾成人吸烟行为调查中研究了具有全国代表性的随机样本。
参与者:本研究包括26名021岁以上15岁或以上的参与者(51%的女性,79%的非吸烟者,16%的15-24岁的16岁),其中排除了31名缺少电子烟使用信息的人(0.1%) 。
主要观察指标:曾经使用过电子烟的患病率是通过整体样本,吸烟状况(当前,以前和从未吸烟)或年龄(15-24岁,25-44岁和≥45岁)来计算的。我们进行了多变量对数二项式回归,以评估所有参与者之间是否曾经使用过电子烟,并根据吸烟状况和年龄分别对亚组进行了相关性评估。
结果:所有参与者中约有3%曾经使用过电子烟。在目前的吸烟者(14%)和18-24岁的人群(7%)中,曾经使用过电子烟的患病率很高。电子烟的使用在15-24岁年龄段的现吸烟者(49-52%)或​​以前吸烟者(22-39%)的人群中尤为普遍。曾经使用过电子烟与吸烟(经调整的患病率(aPR):21.5,95%CI从15.4至29.8,现吸烟者; aPR:8.3,95%CI从15.2至13.1,以前吸烟者),年轻年龄和较高的社会经济地位。在吸烟状态人群中,年龄仍然是使用电子烟的重要因素。在非吸烟者中,男性的电子烟使用率是女性的2.4倍(95%CI为1.5至3.8)。
结论:电子烟在台湾普通人群中很少见,但吸烟者和年轻人中的流行率很高。这项研究突出了电子烟给烟草控制带来的挑战,这需要政策制定者和公共卫生专业人员采取高度优先的行动。电子烟法规应侧重于年轻人。
