Individuals who use both cigarettes and e-cigarettes may have multiple nicotine product use self-identities, each of which may be associated with patterns of use, including cessation.
This study examined changes in "smoker" and "vaper" identities and product use behaviors over one year among adults who used both cigarettes and e-cigarettes. We hypothesized that stronger baseline vaping identities would be associated with higher odds of smoking cessation, and stronger baseline smoking identities would be associated with continued cigarette use.
Participants ( = 364), who were recruited for an observational study of cigarette and e-cigarette use, completed measures of "smoker" and "vaper" identity, nicotine dependence, and product use at baseline and 12 months. We examined associations between smoking and vaping identities and tobacco product use. Logistic regression evaluated the effects of age, gender, and baseline smoking and vaping identities on continued smoking or abstinence at 12 months.
Smoking and vaping identities were independent at baseline ( = .51) but associated at 12 months ( = .0001). At 12 months, "ex-smokers" had higher e-cigarette use than "smokers" and "social/occasional smokers" ( <.0001). Those who identified as "vapers" at baseline had lower odds of smoking at 12 months (OR = 2.27, "non-/ex-vaper" vs "vaper"; OR = 2.05, "social/occasional vaper" vs "vaper").
Smoking and vaping identities are associated with changes in tobacco product use over time.
同时使用香烟和电子烟的个体可能具有多种尼古丁产品使用自我认同，每种认同都可能与使用模式相关，包括戒烟。
本研究调查了同时使用香烟和电子烟的成年人在一年中“吸烟者”和“吸电子烟者”身份以及产品使用行为的变化。我们假设更强的基线吸电子烟身份认同与更高的戒烟几率相关，而更强的基线吸烟身份认同与持续使用香烟相关。
参与一项关于香烟和电子烟使用的观察性研究的参与者（n = 364）在基线和12个月时完成了“吸烟者”和“吸电子烟者”身份、尼古丁依赖及产品使用的测量。我们研究了吸烟和吸电子烟身份认同与烟草产品使用之间的关联。逻辑回归评估了年龄、性别以及基线吸烟和吸电子烟身份认同对12个月时持续吸烟或戒烟的影响。
吸烟和吸电子烟身份认同在基线时相互独立（p = 0.51），但在12个月时相关（p = 0.0001）。在12个月时，“已戒烟者”的电子烟使用量高于“吸烟者”和“社交/偶尔吸烟者”（p < 0.0001）。在基线时将自己认定为“吸电子烟者”的人在12个月时吸烟的几率较低（比值比 = 2.27，“非/前吸电子烟者”与“吸电子烟者”相比；比值比 = 2.05，“社交/偶尔吸电子烟者”与“吸电子烟者”相比）。
吸烟和吸电子烟身份认同与烟草产品使用随时间的变化相关。
