Hintergrund

E-cigarettes, also known as vapes, were originally invented in 2003 by a Chinese pharmacist and are battery-powered nicotine delivery devices that produce aerosols by heating a liquid primarily containing nicotine or other tobacco products. Users inhale the aerosol and experience a physical sensation and similar taste to inhaled tobacco smoke.

E-cigarettes were initially marketed as a safer alternative to traditional combustible cigarettes, with the aim of helping adult smokers quit. However, several scientific studies have pointed to the harmful effects of e-cigarettes on users, especially adolescents, young adults, pregnant women, and non-smokers.

In the United States, e-cigarettes are the most commonly used tobacco product among adolescents. There is growing concern that e-cigarette habits may trigger dependence on more harmful products such as traditional cigarettes, which are associated with premature morbidity and mortality.

In this study, researchers evaluated current trends in e-cigarette use among US adolescents, stratified by key sociodemographic characteristics.

Studiendesign

The researchers used data from the National Youth Tobacco Survey (NYTS) over a period of ten years (2013 – 2022). NYTS is an annual, repeated cross-sectional survey of US middle and high school students. The current study included a total of 186,555 adolescents with complete information on e-cigarette use, age, gender, race, and ethnicity in the analysis.

The study analysis included self-reported age, gender, race, and ethnicity as sociodemographic characteristics. Current e-cigarette use was defined as use in the past 30 days. The researchers calculated overall and sociodemographic characteristic-specific e-cigarette use prevalence, stratified prevalence of e-cigarette use, and assessed changes in prevalence over time (2013 – 2022).

Wichtige Beobachtungen

According to the study estimates, the overall prevalence of e-cigarette use was 3.1% in 2013 and increased to 20.1% in 2019. During the time of the Coronavirus Disease 2019 (COVID-19) pandemic, the prevalence was 7.5% and 9.4% in 2021 and 2022, respectively.

Older adolescents consistently exhibited higher prevalence than younger adolescents. The highest prevalence (30%) among older adolescents was observed in 2019 and remained stable between 2021 and 2022.

Male adolescents showed slightly higher prevalence of e-cigarette use than female adolescents up to 2015. In 2019, the prevalence was nearly equal between males and females. During the pandemic years, the prevalence among females was slightly higher than among males.

Hispanic, non-Hispanic white, and non-Hispanic mixed-race adolescents exhibited higher prevalence of e-cigarette use from 2013 to 2020 compared to non-Hispanic black adolescents. Specifically, the prevalence among Hispanic and non-Hispanic white adolescents was higher than among non-Hispanic black adolescents in 2019. During the pandemic years, the prevalence among Hispanic and non-Hispanic black adolescents increased.

Studienbedeutung

The study identifies a significant increase in the prevalence of e-cigarette use among US adolescents between 2013 and 2019. Although a decrease in use was observed during the pandemic years, the prevalence remains at a concerning level.

Due to limitations associated with the COVID-19 pandemic, the researchers were unable to examine e-cigarette use trends between 2020 and 2021. This is one of the limitations of the study. Another limitation is the inclusion of self-reported information on e-cigarette use and sociodemographic characteristics, which may lead to recall bias.

Overall, the study provides temporal trends of e-cigarette use by age, gender, race, and ethnicity and identifies subgroups with high use that require tobacco prevention support systems. As mentioned by the researchers, future studies should consider additional measures such as frequency of use and choice of flavors to estimate the prevalence of e-cigarette use for a more comprehensive understanding.
