We characterized smokers who are likely to use electronic or "e-"cigarettes to quit smoking.
We obtained cross-sectional data in 2010-2012 from 1567 adult daily smokers in Hawaii using a paper-and-pencil survey. Analyses were conducted using logistic regression.
Of the participants, 13% reported having ever used e-cigarettes to quit smoking. Smokers who had used them reported higher motivation to quit, higher quitting self-efficacy, and longer recent quit duration than did other smokers. Age (odds ratio [OR] = 0.98; 95% confidence interval [CI] = 0.97, 0.99) and Native Hawaiian ethnicity (OR = 0.68; 95% CI = 0.45, 0.99) were inversely associated with increased likelihood of ever using e-cigarettes for cessation. Other significant correlates were higher motivation to quit (OR = 1.14; 95% CI = 1.08, 1.21), quitting self-efficacy (OR = 1.18; 95% CI = 1.06, 1.36), and ever using US Food and Drug Administration (FDA)-approved cessation aids such as nicotine gum (OR = 3.72; 95% CI = 2.67, 5.19).
Smokers who try e-cigarettes to quit smoking appear to be serious about wanting to quit. Despite lack of evidence regarding efficacy, smokers treat e-cigarettes as valid alternatives to FDA-approved cessation aids. Research is needed to test the safety and efficacy of e-cigarettes as cessation aids.
我们对可能使用电子烟戒烟的吸烟者进行了特征描述。
我们利用夏威夷 1567 名成年每日吸烟者的横断面数据，采用纸笔问卷调查法于 2010-2012 年进行研究。我们采用逻辑回归分析进行数据分析。
参与者中，有 13%的人报告曾使用电子烟戒烟。与其他吸烟者相比，使用电子烟戒烟的吸烟者表现出更高的戒烟动机、更强的戒烟自我效能，以及最近戒烟时间更长。年龄（比值比 [OR] = 0.98；95%置信区间 [CI] = 0.97，0.99）和夏威夷原住民种族（OR = 0.68；95% CI = 0.45，0.99）与使用电子烟戒烟的可能性呈负相关。其他显著的相关因素还包括更高的戒烟动机（OR = 1.14；95% CI = 1.08，1.21）、更强的戒烟自我效能（OR = 1.18；95% CI = 1.06，1.36），以及曾使用美国食品药品监督管理局（FDA）批准的戒烟辅助药物，如尼古丁口香糖（OR = 3.72；95% CI = 2.67，5.19）。
试图使用电子烟戒烟的吸烟者似乎非常希望戒烟。尽管电子烟的疗效缺乏证据，但吸烟者将其视为 FDA 批准的戒烟辅助药物的有效替代品。需要开展研究以测试电子烟作为戒烟辅助药物的安全性和疗效。
