Electronic cigarette use is rapidly gaining in popularity. However, little is known about correlates and reasons for electronic cigarette use by women of reproductive age, a group for which the safety and efficacy of electronic cigarette use is of particular interest.
As part of a clinical trial for smoking cessation, we surveyed pregnant smokers about their lifetime use of electronic cigarettes, previous use of any adjunctive treatments for smoking cessation, and use of electronic cigarettes during pregnancy. We examined associations between electronic cigarette use and participant characteristics.
Fifty-three percent (55/103) of participants had previously tried electronic cigarettes. Ever users smoked more cigarettes per day before pregnancy (p = .049), had a greater number of previous quit attempts (p = .033), and were more likely to identify as being Hispanic or non-Hispanic white than never users (p = .027). Fifteen percent of participants (15/103) reported previous use of electronic cigarettes for smoking cessation, which was more common than the use of any specific FDA-approved smoking cessation medication. Fourteen percent of participants (14/103) reported electronic cigarette use during pregnancy, most commonly to quit smoking. A history of substance abuse (p = .043) and more previous quit attempts (p = .018) were associated with electronic cigarette use during pregnancy.
Use of electronic cigarettes to quit smoking may be common in women of reproductive age, including those who are pregnant. More research is needed to determine the risks and benefits of electronic cigarette use in this population of smokers.
This study shows that electronic cigarettes are used by women of reproductive age, including pregnant smokers. The implications of this finding are that there is an urgent need to examine the risks and benefits of electronic cigarette use, especially by pregnant women. The study also shows that electronic cigarettes are commonly used as a smoking cessation aid in women of reproductive age. The greater likelihood of electronic cigarette use compared to proven adjunctive smoking treatments suggests that electronic cigarettes should be examined as a potential aid to cessation in this population.
电子烟的使用正在迅速普及。然而，对于育龄女性使用电子烟的相关因素及原因却知之甚少，而该群体使用电子烟的安全性和有效性尤其令人关注。
作为一项戒烟临床试验的一部分，我们对怀孕吸烟者进行了调查，了解她们一生当中使用电子烟的情况、以往使用过的任何辅助戒烟治疗方法以及孕期使用电子烟的情况。我们研究了电子烟使用与参与者特征之间的关联。
53%（55/103）的参与者曾尝试过电子烟。曾经使用过电子烟的人在怀孕前每天吸烟更多（p = 0.049），以往戒烟尝试次数更多（p = 0.033），并且与从未使用过电子烟的人相比，更有可能认定自己为西班牙裔或非西班牙裔白人（p = 0.027）。15%的参与者（15/103）报告曾使用电子烟来戒烟，这比使用任何一种美国食品药品监督管理局（FDA）批准的特定戒烟药物更为常见。14%的参与者（14/103）报告在孕期使用过电子烟，最常见的原因是戒烟。药物滥用史（p = 0.043）和更多的以往戒烟尝试次数（p = 0.018）与孕期使用电子烟有关。
使用电子烟戒烟在育龄女性中可能很常见，包括那些怀孕的女性。需要更多研究来确定在这一吸烟者群体中使用电子烟的风险和益处。
本研究表明育龄女性，包括怀孕吸烟者，会使用电子烟。这一发现的启示是迫切需要研究使用电子烟的风险和益处，尤其是对孕妇而言。该研究还表明电子烟在育龄女性中常被用作戒烟辅助手段。与经证实的辅助戒烟治疗方法相比，使用电子烟的可能性更大，这表明应将电子烟作为该群体潜在的戒烟辅助手段进行研究。
