导言：鉴于电子烟与未来香烟使用之间的联系，电子烟的流行引起了人们的关注。然而，与现在广泛使用的电子烟相比，这种关联的大部分证据来自早期、效率较低、尼古丁含量较低的电子烟。本研究的目的是研究2018年使用电子烟与随后开始吸烟和继续使用电子烟之间的关系。方法：参与者包括全国15-27岁青年和年轻人纵向小组的成员，他们在2017年报告从未使用过含尼古丁的产品（n = 3360）。在控制了人口统计学和社会心理变量后，逻辑回归分析评估了2018年参与者自我报告的曾经吸过电子烟与2019年曾经吸过香烟、目前吸过香烟和目前吸过电子烟之间的关联。结果：与从未吸过电子烟的人相比，2018年吸过电子烟的人在一年后的2019年吸过电子烟（aOR = 7.29, 95% CI[4.10, 12.97]）、吸过电子烟（aOR = 8.26, 95% CI[3.17, 21.53]）和吸过电子烟（aOR = 9.70, 95% CI[6.41, 14.69]）的几率明显更高。结论：这些发现表明，豆荚式、高尼古丁含量的电子烟使年轻用户与早期效率较低的电子烟一样，面临着向可燃香烟过渡的风险。需要对包括电子烟在内的所有尼古丁产品进行强有力的监管，以防止青少年和年轻人从电子烟转向吸烟。
Introduction: A surge in popularity of e-cigarettes prompts concern given the association between e-cigarettes and future cigarette use. However, much of the evidence for this association comes from early, less efficient, and lower nicotine e-cigarettes than are available and widely used now. The goal of this study was to examine the relationship between e-cigarette use in 2018 and subsequent smoking initiation and continued e-cigarette use.Methods: Participants included members of a national longitudinal panel of youth and young adults aged 15-27 who, in 2017, reported never having used a nicotine containing product (n = 3360). Logistic regression analyses assessed associations between participants' self-reported ever e-cigarette use in 2018 and ever cigarette use, current cigarette use, and current e-cigarette use in 2019, after controlling for demographic and psychosocial variables.Results: Compared with those who still had never used an e-cigarette, those who reported ever e-cigarette use in 2018 had significantly higher odds of ever cigarette use (aOR = 7.29, 95% CI [4.10, 12.97]), current cigarette use (aOR = 8.26, 95% CI [3.17, 21.53]), and current e-cigarette use (aOR = 9.70, 95% CI [6.41, 14.69]) one year later in 2019.Conclusions: These findings show that the pod mod style, high nicotine containing e-cigarettes subject young users to the same risks of transitioning to combustible cigarettes as their earlier, less efficient predecessors. Strong regulation of all nicotine products, including e-cigarettes, is needed to prevent the trajectory of e-cigarette to cigarette use among youth and young adults.
