项目摘要

PROJECT ABSTRACT Use of e-cigarettes or vapes is increasingly popular. Vulnerable populations most likely to vape include adolescents and young adults, sexual minorities, and people with poor mental health. Vaping is likely less harmful overall than smoking combustible cigarettes. Nevertheless, some users vape at frequencies that far exceed what they prefer, which we term uncontrolled vaping, augmenting health risks and producing greater addiction. In light of these concerns, some e-cigarette users may take actions intended to get their vaping under control. This vaping restraint could reduce health risks and support cessation of tobacco products including e-cigarettes. Vaping restraint strategies may present more challenges than efforts to reduce smoking because e-cigarette portions and refill sizes are unregulated, leaving users without familiar cues to encourage portion control (e.g., the end of a cigarette). However, the prevalence of uncontrolled vaping and restraint strategies is unknown, including for vulnerable populations. To fill these important gaps, the overarching goal of the proposed research is to understand uncontrolled vaping as well as vaping restraint strategies, which likely vary substantially across vulnerable populations, different device types, and dual use with combustible cigarettes. We build on the Process Model of Self-Control, hypothesizing greater impact of situational than cognitive restraint strategies. In Aim 1, we will develop measures of uncontrolled vaping and restraint strategies. We will conduct phone interviews with adolescent, young adult, and adult current e- cigarette users to identify language they employ to describe uncontrolled use and vaping restraint and then develop survey measures. In Aim 2, we will characterize the prevalence and correlates of both uncontrolled vaping and restraint strategies. We will survey a probability sample of current e-cigarette users (including adolescents, young adults and adults) and evaluate the suitability of the new measures among vulnerable populations. We will then calculate national estimates of uncontrolled use and vaping restraint strategies, and examine whether these outcomes are more common among vulnerable populations, certain device type users, and dual users. In Aim 3, we will establish the longitudinal impact of vaping restraint strategies on uncontrolled vaping. We will conduct a follow-up online survey at 12 months with the e- cigarette users from the Aim 2 sample. We will examine the association of baseline vaping restraint with uncontrolled vaping and smoking behavior 12 months later. Findings from the proposed research can inform regulatory science for e-cigarettes (e.g., by creating product standards for refill size and device features associated with uncontrolled use). The proposed research is responsive to FDA and NCI scientific interest areas of Addiction and Behavior.

项目摘要使用电子烟或VAP越来越流行。最有可能vape的脆弱人群包括青少年和年轻人，性少数群体以及精神健康不良的人。烟雾可能会更少总体上比吸烟可燃香烟有害。然而，一些用户vape的频率很远超出他们喜欢的东西，我们认为这是不受控制的烟雾，增加了健康风险并产生更大的瘾。鉴于这些问题，一些电子烟用户可能会采取旨在进行烟雾的行动在控制之下。这种烟雾约束可以降低健康风险，并支持停止烟草产品包括电子烟。与减少吸烟相比因为电子烟的部分和补充尺寸不受监管，所以用户没有熟悉的提示来鼓励部分控制（例如，香烟的末端）。但是，不受控制的烟与克制的流行率策略是未知的，包括弱势群体。为了填补这些重要的空白，总体目标拟议的研究是了解不受控制的烟以及烟雾约束策略，在脆弱的人群，不同的设备类型和双重用途的情况下，可能会有很大差异可燃的香烟。我们以自我控制的过程模型为基础，假设情境比认知约束策略。在AIM 1中，我们将制定不受控制的Vaping的措施和约束策略。我们将对青少年，年轻和成人当前的E-进行电话采访香烟用户确定他们采用的语言来描述不受控制的使用和vaping限制，然后制定调查措施。在AIM 2中，我们将表征两者的流行和相关性不受控制的烟与约束策略。我们将调查当前电子烟的概率样本用户（包括青少年，年轻人和成年人），并评估新措施的适用性脆弱的人群。然后，我们将计算出不受控制的使用和烟限制的国家估计策略，并检查这些结果在脆弱人群中是否更常见设备类型用户和双用户。在AIM 3中，我们将建立vaping限制的纵向影响关于不受控制的烟的策略。我们将在12个月的E-中进行12个月的后续在线调查 AIM 2样本中的香烟用户。我们将研究基线烟的约束与 12个月后，不受控制的烟与吸烟行为。拟议研究的发现可以告知电子烟的监管科学（例如，通过为补充尺寸和设备功能创建产品标准与不受控制的使用相关）。拟议的研究对FDA和NCI科学兴趣有反应成瘾和行为领域。
