Note. AOR = adjusted odds ratio; CI = confidence interval; NH = non-Hispanic; OR = odds ratio. The sample size was n = 3628.
Dual use (co-use of e-cigarettes and cigarettes or other tobacco products) was the dependent variable (yes vs no).
Adjusted by age, gender, and tobacco use by a household member.
Occasional use (1‒5 days in the past 30 days) and frequent use (≥20 days in the past 30 days) were the dependent variables (yes vs no) and analyzed separately.
Adjusted by age, gender, current cigarette smoking, current other tobacco use, and tobacco use by a household member.
Flavored e-cigarette use (tasted like menthol [mint], alcohol [wine, cognac], candy, fruit, chocolate, or any other flavors) was the dependent variable (yes vs no). Flavored e-cigarette use was correlated with the number of days using e-cigarettes in the past 30 d. In 2019, the proportions of flavored e-cigarette use among current e-cigarette users reporting e-cigarettes 1–2 days, 3–5 days, 6–9 days, 10–19 days, 20–29 days, and all 30 days were 54.2%, 66.4%, 71.6%, 76.0%, 79.6%, and 84.1%, respectively.
Adjusted by age, gender, current cigarette smoking, current other tobacco use, tobacco use by a household member, and the number of days using e-cigarettes in the past 30 days.
