Correlates of Perceptions,
Use, and Intention to Use Heated Tobacco Products among US Young Adults in 2020.
Nicotine Tob Res. 2022;24(12):1968-1977. doi:10.1093/ntr/ntac185
Introduction. Despite
the increased heated tobacco product (HTP) marketing in the United States,
little is known about HTP perceptions and correlates of HTP use and use
intentions among young adults.
Aims and methods. Using
2020 cross-sectional data from 2,470 young adults (ages 18-34) from 6 US
metropolitan areas, we conducted exploratory factor analysis to identify
factors regarding perceived utility/appeal of HTPs, specifically IQOS, and
examined these factors in relation to lifetime HTP use and use intentions,
using multivariable logistic and linear regression, respectively.
Results. 19.1%
had heard of HTPs and 4.1% ever used HTPs; 14.7% had heard of IQOS specifically
and 2.8% were ever-users. Use intentions were low (M = 1.27, scale: 1 = not at
all to 7 = extremely). Factor analysis identified five perceived utility/appeal
factors: innovation (M = 3.17, scale: 1 = not at all to 7 = extremely),
cigarette substitute (M = 2.99), and youth appeal (M = 2.82),
e-cigarette/nicotine substitute (M = 2.36), and fashionable (M = 2.04).
Controlling for sociodemographics and other tobacco use, perceiving IQOS as
more fashionable and e-cigarette substitutes positively correlated with
lifetime HTP use (aOR = 1.60, 95%CI = 1.17, 2.17; aOR = 1.48, 95%CI = 1.11,
1.97, respectively) and use intentions (β = 0.26, 95%CI = 0.21, 0.30; β = 0.14,
95%CI = 0.09, 0.18); perceiving IQOS as cigarette substitutes negatively
correlated with ever use (aOR = 0.74, 95%CI = 0.56, 0.97) and use intentions (β
= -0.06, 95%CI = -0.10, -0.03). Correlation patterns were similar among
past-month cigarette, e-cigarette, and any-tobacco users.
Conclusions. Although
HTP awareness and use were low, monitoring HTP perceptions and reasons for use
as HTPs become more prominent is critical in anticipating their potential
impact, particularly as more products seek FDA authorization to use reduced
risk or exposure marketing claims.
Implications. Awareness,
ever use, and intentions to use heated tobacco products (HTPs) were low among
US young adults in 2020. Perceiving IQOS as fashionable and an e-cigarette
substitute were positively correlated with ever use and intention to use HTPs.
In addition, perceiving IQOS as a cigarette substitute was negatively
correlated with ever use of HTPs and HTP use intentions. Continued surveillance
on perceptions and use behaviors is needed to better understand use patterns,
intentions to use, and reasons for using HTPs.
