RESUMEN
PURPOSE: To examine ice flavor use and its correlates among middle and high school students who currently (any past 30-day) used e-cigarettes. METHODS: The 2023 National Youth Tobacco Survey (NYTS) assessed for the first time the use of e-cigarette flavors that included the word "ice" or "iced" in the name. Using logistic regression, data from the 2023 NYTS were used to examine differences in sociodemographic characteristics and tobacco use behaviors by ice flavor use among students who currently used e-cigarettes (n=1,565). RESULTS: Among middle and high school students who currently used e-cigarettes, an estimated 1.1 million or 57.9% reported ice flavor use. Youth who currently used e-cigarettes were more likely to use ice flavors if they used e-cigarettes on ≥20 of the past 30 days compared to 1-5 days (adjusted Odds Ratio [aOR]=2.31, 95% CI: 1.36-3.94); used fruit (aOR=2.27, 95% CI: 1.36-3.80), candy (aOR=2.73, 95% CI:1.54-4.82), or mint flavors (aOR=3.63, 95% CI:1.98-6.65) compared to those who did not use the respective flavor type; reported any nicotine dependence compared to those who did not (aOR= 1.71, 95% CI:1.04-2.80); or had mild/moderate (aOR=1.97, 95% CI: 1.01-3.83) or severe psychological distress (aOR=2.41, 95% CI: 1.25-4.62) compared to those without psychological distress. CONCLUSIONS: The present study found that ice-flavored e-cigarette use among youth was associated with use of e-cigarettes on ≥20 days, use of fruit, candy, or mint flavors, any symptoms of nicotine dependence, and psychological distress (mild/moderate, severe). Emergence of novel flavor categories and features of e-cigarettes warrant continued surveillance to provide an understanding of associated use patterns, especially among youth. IMPLICATIONS: This study examined ice flavor use and its correlates among middle and high school students who currently used e-cigarettes. Ice-flavored e-cigarette use among youth was positively associated with frequent e-cigarettes use, use of fruit, candy, or mint flavors, and any symptoms of nicotine dependence. Additionally, the likelihood of ice-flavored e-cigarette use was associated with severity of psychological distress.
RESUMEN
PURPOSE: To examine whether survey setting was associated with youth reporting of current (past 30-day) use of any tobacco product, e-cigarettes, cigarettes, and cigars. METHODS: Data from the 2021 National Youth Tobacco Survey (NYTS) were used to estimate the prevalence of current use of any tobacco product, e-cigarettes, cigarettes, and cigars by survey setting, sociodemographic characteristics, peer tobacco use, and other tobacco product use. Multivariable regression was used to test the impact of survey setting on current tobacco use. Tobacco access sources among current users were compared by survey setting. RESULTS: Among students who participated in the 2021 NYTS, 50.8% reported taking the survey on school campus and 49.2% at home/other place. The prevalence of current use of any tobacco product, e-cigarettes, cigarettes, and cigars was higher among students completing the survey on school campus than at home/other place. After adjusting for covariates, this association persisted only for current use of any tobacco product (adjusted odds ratio = 1.57; 95% confidence interval, 1.28-1.91) and e-cigarettes (adjusted odds ratio = 1.43; 95% confidence interval, 1.20-1.71). Current users reported similar sources of access to tobacco products, regardless of survey setting. DISCUSSION: The likelihood of youth reporting current use of any tobacco product and e-cigarettes differed by survey setting. Such differences could be due to lack of privacy at home, peer influence in school settings, and other unmeasured characteristics. Methodological changes were made due to COVID-19; caution is warranted in comparing results from the 2021 NYTS with those of previous or future NYTS conducted primarily on school campus.
