A leading brand of heated tobacco products (HTPs), IQOS, was authorized to be sold in the United States in 2019. Researchers have examined the awareness and use of HTPs among US adults. In this study, we examined high school students' awareness, use, and susceptibility pertaining to HTPs.
A large, cross-sectional population survey of randomly sampled 10th- and 12th-graders in California ( = 150 516) was conducted online during school hours from September 2019 to March 2020.
Overall, 8.9% (95% confidence interval [CI], 8.7%-9.1%) of California high school students had heard of HTPs. Approximately 0.67% (95% CI, 0.61%-0.73%) had ever tried HTPs, and 0.20% (95% CI, 0.17%-0.23%) were current users (ie, ∼30% of ever users continued to use HTPs at the time of survey). Among those who never tried HTPs, 18.3% (95% CI, 17.9%-18.8%) were susceptible to future use. The susceptibility to HTP use was greater among users of cigarettes or e-cigarettes than among nonusers.
The awareness of HTPs among adolescents was remarkable given the low availability of products at the time of survey. Only a small percentage of adolescents experimented with HTPs. However, almost a third of those who had experimented with HTPs continued to use them. This high ratio and the fact that almost 1 out of 5 never users were susceptible to future HTP use should put the public health community on high alert as more HTP products are coming into the market, with promotion of these products likely to increase.
一款加热烟草产品（HTP）的领先品牌 IQOS 于 2019 年获准在美国销售。研究人员已经研究了美国成年人对 HTP 的认知和使用情况。在这项研究中，我们研究了高中生对 HTP 的认知、使用和易感性。
在 2019 年 9 月至 2020 年 3 月期间，在加利福尼亚州的 10 年级和 12 年级学生中进行了一项大型、横断面的随机抽样人群调查，调查是在上课时间通过在线方式进行的。
总体而言，8.9%（95%置信区间[CI]，8.7%-9.1%）的加州高中生听说过 HTP。约 0.67%（95% CI，0.61%-0.73%）曾尝试过 HTP，0.20%（95% CI，0.17%-0.23%）为当前使用者（即在调查时，约 30%的曾使用者继续使用 HTP）。在从未尝试过 HTP 的人中，有 18.3%（95% CI，17.9%-18.8%）有未来使用的易感性。与非使用者相比，香烟或电子烟使用者对 HTP 使用的易感性更高。
鉴于调查时产品供应有限，青少年对 HTP 的认知令人瞩目。只有一小部分青少年尝试了 HTP。然而，几乎三分之一曾尝试过 HTP 的人继续使用它们。这一高比例以及近五分之一的从未使用者未来有使用 HTP 的易感性，应该使公共卫生界高度警惕，因为更多的 HTP 产品正在进入市场，这些产品的推广可能会增加。
