Introduction

Given high youth e-cigarette use, it is important to investigate how traits, like impulsivity, may be associated with youth e-cigarette use behaviors. The study aim is to determine if impulsivity is associated with trying more e-cigarette flavors and device types, and greater frequency of e-cigarette use.

Method

Cross sectional survey data from CT high schoolers (n = 4875, 6 schools) were collected in 2019. Lifetime (ever) e-cigarette users (n = 2313) completed the Brief Barrett Impulsivity Scale, which contains two subscales; behavioral impulsivity and impaired self-control. Among lifetime users, associations between impulsivity subscales and number of e-cigarette flavors tried, e-cigarette devices tried, and past 30-day frequency of e-cigarette use were examined using regression models. Additionally, associations of impulsivity and use frequency were examined among only current e-cigarette users (≥1 day of use in past 30; n = 1327). School, age, race/ethnicity, vaping initiation age, other tobacco product use, and sex were included as covariates in models.

Results

Higher behavioral impulsivity was associated with greater number of e-cigarette flavors tried (AOR: 1.06, 95% CI: 1.02, 1.11, p <.008) and higher frequency of past 30-day use both among ever and current e-cigarette users (AOR: 1.26, 95%CI:1.10,1.44, p <.001; AOR: 1.12, 95%CI:1.02,1.22, p <.02), but not number of e-cigarette devices tried. Impaired self-control was not associated with any outcomes.

Conclusion

Youth with higher behavioral impulsivity may be more at risk for using more e-cigarette flavors and using e-cigarettes more frequently. Regulations aimed at reducing flavor availability among youth and interventions targeting impulsive behavior may be important for this population.

青少年冲动与电子烟设备的使用、口味和使用频率之间的关联

介绍

鉴于青少年电子烟使用率很高，研究冲动等特征如何与青少年电子烟使用行为相关非常重要。该研究的目的是确定冲动是否与尝试更多电子烟口味和设备类型以及更高的电子烟使用频率有关。

方法

2019 年收集了康涅狄格州高中生（n = 4875，6 所学校）的横断面调查数据。终生（曾经）电子烟使用者 (n = 2313) 完成了简明巴雷特冲动量表，其中包含两个子量表：行为冲动和自我控制能力受损。在终生使用者中，使用回归模型检查了冲动子量表与尝试过的电子烟口味数量、尝试过的电子烟设备以及过去 30 天电子烟使用频率之间的关联。此外，仅在当前电子烟使用者（过去 30 天内使用≥1 天；n = 1327）中检查了冲动性和使用频率的关联。学校、年龄、种族/民族、开始吸电子烟的年龄、其他烟草产品的使用和性别都作为协变量纳入模型中。

结果

较高的行为冲动性与尝试电子烟口味的数量较多（AOR：1.06，95% CI：1.02、1.11，p  <.008）以及曾经和当前电子烟使用者过去 30 天使用频率较高相关（AOR：1.26，95%CI：1.10,1.44，p  <.001；AOR：1.12，95%CI：1.02,1.22，p  <.02），但不是尝试的电子烟设备的数量。自我控制受损与任何结果均无关。

结论

行为冲动性较高的青少年可能更容易使用更多电子烟口味和更频繁地使用电子烟。旨在减少青少年风味供应的法规和针对冲动行为的干预措施对于这一人群可能很重要。
