Awareness and Use of
Heated Tobacco Products among Middle School and High School Students, United
States, 2019-2020.
Nicotine Tob Res. 2022;24(8):1273-1280. doi:10.1093/ntr/ntac065
Purpose. Heated
tobacco products (HTP) heat-processed tobacco leaf into an aerosol inhaled by
the user. This study assessed prevalence and correlates of HTP awareness, ever
use, and current use among US middle and high school students.
Methods. Data
came from the 2019 and 2020 National Youth Tobacco Survey, a cross-sectional
survey of US public and private, middle and high school students. HTP
awareness, ever use, and current (past 30-day) use were assessed. Weighted
prevalence estimates and adjusted prevalence ratios (aPR) were assessed overall
and by sex, school level, race/ethnicity, and current other tobacco product
use.
Results. In
2019, 12.8% (3.44 million) of all students reported HTP awareness, increasing
to 19.3% (5.29 million) in 2020 (p < .01). Ever [2019: 2.6% (630 000); 2020:
2.4% (620 000)] and current [2019: 1.6% (420 000); 2020: 1.4% (370 000)] HTP
use did not significantly change from 2019 to 2020. Current e-cigarette users
were more likely to report ever (2020 aPR = 1.79, 95% CI:1.23, 2.62) or current
HTP use (2019 aPR = 5.16, 95% CI: 3.48, 7.67; 2020 aPR = 3.39, 95% CI: 2.10,
5.47) than nonusers. In both years, ever and current HTP use was more likely
among current combustible (aPR range = 3.59-8.17) and smokeless tobacco product
(aPR range = 2.99-4.09) users than nonusers.
Conclusions. HTP
awareness increased 51% among US students during 2019-2020; however, HTP use
did not significantly change during this period. Students who used other tobacco
products were more likely to currently use HTPs. Estimates of HTP awareness and
use provided serve as a baseline as future monitoring of these products is
warranted.
Implications. Awareness
of heated tobacco products (HTPs) increased among US youth from 2019 to 2020;
however, HTP use did not change. These estimates of HTP awareness and use serve
as a baseline for future surveillance of these products as their availability
in the US increases.
