Abbreviation: RRR, relative risk ratio.
Data source: Florida Youth Tobacco Survey.
Unadjusted multinomial logistic regression models examined the bivariate relationship between predictors and outcome.
Adjusted multinomial logistic regression model included all variables in 1 model.
Vaped, but not vaped in the past 30 days.
Vaped in the past 30 days.
Never used e-cigarette reference group is n = 7,368.
Nondaily includes every few months, every few weeks, 1–2 days/week, and 3–5 days/week.
Daily includes once per day or several times per day.
Assessed using the question, Does anyone who lives in your home use any of the following products? (Do not count yourself), and response options were cigarettes, cigars, chewing tobacco, snuff, or dip, hookahs, and electronic vaping products.
Assessed using the question, During the past 12 months, did you ever feel so sad or hopeless that for ≥2 consecutive weeks you stopped usual activities?
