A growing body of work has identified short-term harms of e-cigarette use that may be indicative of long-term harm. Ecological momentary assessment (EMA) is a methodology that can contribute to these efforts, as it lends itself to capturing moment-to-moment changes in symptoms as people go about their natural environments. This study leveraged EMA to assess the correspondence between instances of e-cigarette use and changes in self-reported health.
Our analytical sample comprised 173 youth living in Ohio (ages 15-24). At enrollment, 60 had used e-cigarettes in the last 3 months, and 113 had never used e-cigarettes. All participants completed a baseline survey. Then, for 14 d, participants were prompted at 3 random times/d to complete EMA surveys; for all participants, these assessed e-cigarette use, self-reported lung health, e-cigarette craving, and withdrawal symptoms.
Among youth enrolled for e-cigarette use, an average of 50.8% of EMAs reported an instance of e-cigarette use. Multilevel models (MLMs) indicated that instances of e-cigarette use were associated with worse self-reported lung health (point estimate: -0.143, 95% CI: -0.203, -0.083 on a 1-5 Likert-type scale). Using an e-cigarette was also associated with: instances of coughing; reduced e-cigarette craving; and feeling less drowsy, anxious, and irritable.
Although infrequent, periods of poor respiratory symptoms were associated with recent instances of youth e-cigarette use. Instance of e-cigarette use were also associated with temporary reductions in craving and withdrawal. This study adds to emerging knowledge on e-cigarette harms by demonstrating associations at a granular level, across an ecologically valid context.
越来越多的研究已经确定了电子烟使用的短期危害，这些危害可能预示着长期危害。生态瞬时评估（EMA）是一种有助于这些研究的方法，因为它适合捕捉人们在自然环境中时症状的瞬间变化。本研究利用EMA来评估电子烟使用情况与自我报告的健康变化之间的对应关系。
我们的分析样本包括173名居住在俄亥俄州的青少年（年龄在15 - 24岁之间）。在入组时，60人在过去3个月内使用过电子烟，113人从未使用过电子烟。所有参与者都完成了一项基线调查。然后，在14天内，参与者每天被随机提示3次以完成EMA调查；对所有参与者来说，这些调查评估了电子烟使用情况、自我报告的肺部健康、对电子烟的渴望以及戒断症状。
在登记使用电子烟的青少年中，平均50.8%的EMA报告有电子烟使用情况。多水平模型（MLMs）表明，电子烟使用情况与自我报告的较差肺部健康相关（点估计值：-0.143，95%置信区间：-0.203，-0.083，采用1 - 5李克特量表）。使用电子烟还与以下情况相关：咳嗽情况；对电子烟渴望的降低；以及感觉困倦、焦虑和易怒程度减轻。
尽管不常见，但呼吸症状不佳的时期与青少年近期使用电子烟的情况有关。电子烟使用情况还与渴望和戒断的暂时减少有关。本研究通过在生态有效背景下的细粒度层面展示关联，增加了关于电子烟危害的新知识。
