Abstract
PURPOSE: To examine trends in single, dual, and polytobacco use between 2014-2020 for US youth and to identify disparities in these trends by grade level, sex, and race/ethnicity. DESIGN: A secondary analysis of the National Youth Tobacco Survey (NYTS). SUBJECTS: A total of 122 566 students. MEASURES: Past 30-day exclusive use of cigarettes, e-cigarettes, other combustibles (cigars, little cigars, cigarillos, hookah, pipe tobacco, bidis) and smokeless tobacco (snus, smokeless, dissolvable); dual use of each product with e-cigarettes; polyuse with e-cigarettes; dual/polyuse without e-cigarettes. ANALYSIS: Multivariable modified Poisson regression. RESULTS: Compared to 2014, exclusive e-cigarette use (APR = 2.51, 95% CI: 1.96, 3.21) trended upward while exclusive cigarette (APR = .34, 95% CI: .23, .50), 'other' combustibles (APR = .47, 95% CI: .37, .58), and smokeless tobacco (APR = .40, 95% CI: .25, .65) use trended downward in 2020. Polytobacco use with and without e-cigarettes trended downward in 2020 compared to 2014. We also saw differences in trends across sociodemographic groups. Comparing 2020 to 2014, exclusive e-cigarette use was higher for females than males, 'other' combustible tobacco use remained stable for Non-Hispanic Black students but decreased for other racial/ethnic groups, and dual e-cigarette/cigarette use trended upward more for middle school students than high school students. CONCLUSIONS: Despite decreased trends in tobacco product use without e-cigarettes between 2014-2020, differences in tobacco product use trends by grade level, sex, and race/ethnicity were identified. Prevention efforts targeting disparities in tobacco product use are needed.
