In April 2019, the U.S. Food and Drug Administration authorized the marketing of IQOS Heated Tobacco Products (HTPs) in the United States. This study sought to assess self-reported awareness and use of HTPs among U.S. students in 2019.
This study analyzed the 2019 National Youth Tobacco Survey (NYTS), a cross-sectional, school-based, nationally representative survey (n = 19,018). Weighted estimates of the prevalence of self-reported awareness, ever use, and current use (past 30-day) of HTPs were reported and multivariable logistic regression models were performed to examine the factors associated with HTPs awareness and use.
In 2019, 12.8 % (a population estimate of 3,438,000), 2.4 % (632,000), and 1.6 % (425,000) of U.S. students reported awareness, ever use, and current use of HTPs, respectively. In the multivariate analysis, high school students were less likely than middle school students to report awareness (AOR = 0.7 [0.6-0.8]) of HTPs. Females (vs. males) had a lower odd of reporting ever use of HTPs (AOR = 0.5 [0.4-0.8]), while Hispanics (vs. non-Hispanic Whites) had higher odds of reporting current use of HTPs (AOR = 1.6 [1.1-2.5]). Current cigarette smoking, e-cigarette use, and other tobacco use are associated with higher odds of HTPs ever and current use than non-users.
HTP use is emerging among U.S. adolescents. This study identified an elevated risk of HTP use among middle school students, Hispanics, current tobacco users, and those who live with a household member using HTPs. Continuous surveillance and educational campaigns on the harmfulness of HTPs are warranted.
2019 年 4 月，美国食品和药物管理局批准 IQOS 加热烟草产品（HTP）在美国上市。本研究旨在评估 2019 年美国学生对 HTP 的自我报告意识和使用情况。
本研究分析了 2019 年全国青年烟草调查（NYTS），这是一项基于学校的、具有全国代表性的横断面调查（n=19018）。报告了自我报告意识、曾经使用和当前使用（过去 30 天）HTP 的加权估计，并进行了多变量逻辑回归模型分析，以研究与 HTP 意识和使用相关的因素。
2019 年，12.8%（估计有 343.8 万人）、2.4%（63.2 万人）和 1.6%（42.5 万人）的美国学生报告了对 HTP 的意识、曾经使用和当前使用。在多变量分析中，高中生比中学生更不可能报告对 HTP 的意识（AOR=0.7[0.6-0.8]）。女性（与男性相比）报告曾经使用 HTP 的几率较低（AOR=0.5[0.4-0.8]），而西班牙裔（与非西班牙裔白人相比）报告当前使用 HTP 的几率较高（AOR=1.6[1.1-2.5]）。当前吸烟、使用电子烟和其他烟草使用与 HTP 曾经和当前使用的几率较高有关，而非使用者的几率较低。
HTP 在美国家庭中使用正在出现。本研究发现，中学生、西班牙裔、当前烟草使用者和与使用 HTP 的家庭成员同住的人，使用 HTP 的风险更高。需要对 HTP 的危害性进行持续监测和开展教育宣传活动。
