背景电子香烟（e-cigarettes）正在做广告，并与合成尼古丁一起销售。很少有研究探讨了年轻人的合成尼古丁或合成尼古丁的描述符的影响的认知e-cigaretts.MethodsParticipants是一个样本的1603美国青少年（13-17岁）从一个基于概率的面板。该调查评估了电子烟中尼古丁来源的知识（来自“烟草植物”或“烟草植物以外的其他来源”）以及对含有合成尼古丁的电子烟的认识。然后，在2×3析因设计的受试者间实验中，我们操纵了电子烟产品上的描述符：（1）尼古丁标签（包括“尼古丁”一词：存在或不存在）和（2）来源标签（包括一个来源：“无烟草”、“合成”或不存在）。同样，大多数人不确定（48.2%）或不认为（8.1%）电子烟中的尼古丁来自其他来源。对含有合成尼古丁的电子烟的认识程度为低至中等（28.7%），使用电子烟的青少年的认识程度较高（48.0%）。虽然没有观察到主要影响，但电子烟状态和实验操作之间存在显着的三向相互作用。与“合成尼古丁”相比，“无烟草尼古丁”的描述增加了购买意愿（简单斜率：1.20，95% CI 0.65 - 1.75）和“尼古丁”（简单斜率：1.20,95%CI 0.67至1.73）对于使用电子烟的青少年。将合成尼古丁描述为“不含烟草的尼古丁”，增加了使用电子烟的年轻人的购买意愿。
BackgroundElectronic cigarettes (e-cigarettes) are being advertised and sold with synthetic nicotine. Little research has examined youth awareness of synthetic nicotine or the impact of synthetic nicotine descriptors on perceptions of e-cigarettes.MethodsParticipants were a sample of 1603 US adolescents (aged 13–17 years) from a probability-based panel. The survey assessed knowledge of nicotine source in e-cigarettes (from ‘tobacco plants’ or ‘other sources besides tobacco plants’) and awareness of e-cigarettes containing synthetic nicotine. Then, in a between-subjects experiment with a 2×3 factorial design, we manipulated descriptors on e-cigarette products: (1) nicotine label (inclusion of the word ‘nicotine’: present or absent) and (2) source label (inclusion of a source: ‘tobacco-free’, ‘synthetic’ or absent).ResultsMost youth were either unsure (48.1%) or did not think (20.2%) that nicotine in e-cigarettes comes from tobacco plants; similarly, most were unsure (48.2%) or did not think (8.1%) that nicotine in e-cigarettes comes from other sources. There was low-to-moderate awareness of e-cigarettes containing synthetic nicotine (28.7%), with higher awareness among youth who use e-cigarettes (48.0%). While no main effects were observed, there was a significant three-way interaction between e-cigarette status and the experimental manipulations. The ‘tobacco-free nicotine’ descriptor increased purchase intentions relative to ‘synthetic nicotine’ (simple slope: 1.20, 95% CI 0.65 to 1.75) and ‘nicotine’ (simple slope: 1.20, 95% CI 0.67 to 1.73) for youth who use e-cigarettes.ConclusionsMost US youth do not know or have incorrect beliefs about the sources of nicotine in e-cigarettes and describing synthetic nicotine as ‘tobacco-free nicotine’ increases purchase intentions among youth who use e-cigarettes.
