背景：人们对青少年使用的电子烟的特点知之甚少。了解青少年使用电子烟的产品情况可以为咨询和政策策略提供信息。方法：结果来自烟草与健康研究人口评估第1波13651名青少年和第2波12172名青少年，这是一项具有全国代表性的纵向研究。过去30天的常规电子烟用户被问及他们大部分时间使用的电子烟的特征。结果：在波1和波2中，分别有2.1%和2.8%的青少年在过去30天内是常规用户。这些青少年更多地使用可充电设备而不是一次性设备（第1波：76.0%；第2波：82.9%），使用可充电设备而不是非可充电设备（第1波：66.6%；第2波：84.4%），并且倾向于不使用药筒系统（第1波：33.7%；第2波：30.5%）。大多数超过30天的青少年用户（第1波：87.5%；第2波：89.4%）报告使用调味电子烟。使用频率的增加与可充电电子烟（第一波调整比值比[aOR]: 2.7；第二波调整比值比：2.7）和可充电电子烟（第一波调整比值比：2.0；第二波调整比值比：2.7;P < 0.05）的使用有关。浪潮1中的大多数用户在浪潮2中没有继续常规使用（70.2%）。在第1波中继续使用和报告使用封闭系统（不可充电和/或不可再充）的患者中，大多数在第2波中进展为开放系统（可充电和可再充）。结论：大多数青少年使用开放式系统电子烟，频繁使用者更有可能使用开放式系统电子烟。大多数普通用户使用的是可充电设备。产品偏好的变化表明出现了一种初级产品现象，逐渐转向质量控制较弱、可能增加健康风险的产品。
BACKGROUND: Little is known about the characteristics of electronic cigarettes (e-cigarettes) used by adolescents. Understanding the product landscape of adolescent e-cigarette use may inform counseling and policy strategies.METHODS: Results are from 13651 adolescents in wave 1 and 12172 adolescents in wave 2 of the Population Assessment of Tobacco and Health Study, a nationally representative longitudinal study. Past 30-day regular e-cigarettes users were asked about the characteristics of the e-cigarette they used most of the time.RESULTS: In waves 1 and 2, 2.1% and 2.8% of adolescents were regular users in the past 30 days, respectively. These adolescents more often used rechargeable rather than disposable devices (wave 1: 76.0%; wave 2: 82.9%) and refillable rather than nonrefillable devices (wave 1: 66.6%; wave 2: 84.4%) and tended not to use cartridge systems (wave 1: 33.7%; wave 2: 30.5%). Most adolescent past 30-day users (wave 1: 87.5%; wave 2: 89.4%) reported using flavored e-cigarettes. An increased frequency of use was associated with the use of rechargeable (wave 1 adjusted odds ratio [aOR]: 2.7; wave 2 aOR: 2.7) and refillable e-cigarettes (wave 1 aOR: 2.0; wave 2 aOR: 2.7; P < .05). Most users in wave 1 did not continue regular use in wave 2 (70.2%). Among those who continued to use and had reported using closed systems (nonrechargeable and/or nonrefillable) in wave 1, most had progressed to open systems (rechargeable and refillable) in wave 2.CONCLUSIONS: Most adolescents use open-system e-cigarettes, and frequent users are even more likely to use open-system e-cigarettes. The majority of regular users use rechargeable devices that are refillable. A change in product preferences across waves suggests a starter product phenomenon, with a graduation to products that have weaker quality controls and may increase health risks.
