Notes:
Abbreviations: P30D = past 30-day; ENDS = electronic nicotine delivery system; aOR = adjusted odds ratio; CI = confidence interval; N/A = not applicable
The percentages and odds ratios in the table are based on weighted data.
Denominator N (unweighted number of observations) for aOR in “Cigarettes” = 14,619
Denominator N (unweighted number of observations) for aOR in “ENDS” = 2,550
Denominator N (unweighted number of observations) for aOR in “Cigars” = 2,355
Denominator N (unweighted number of observations) for aOR in “Hookah” = 1,293
Denominator N (unweighted number of observations) for aOR in “Smokeless” = 2,172
Tobacco product types were categorized into five groups: cigarettes, ENDS (e-cigarettes at Wave 1, and e-cigarettes, e-cigars, e-pipes, and e-hookah at Waves 2 & 3), cigars (traditional cigars, cigarillos, filtered cigars), hookah, and smokeless tobacco (loose snus, moist snuff, dip, spit, chewing tobacco, and snus pouches).
For each of the five tobacco products, use is defined with respect to the given tobacco product/any tobacco product:
Current established use is defined for cigarettes as currently smoking every day or some days and having smoked at least 100 cigarettes in the lifetime; current established use is defined for other tobacco products as currently using the product every day or some days and having ever used the product “fairly regularly”;
Making a quit attempt is defined as having tried to quit using the given tobacco product in the past 12 months (or having tried to quit using tobacco products generally in the past 12 months if the respondent was using more than one type of tobacco product at baseline), or indicating not currently using the given tobacco product (or tobacco products generally) at follow-up (i.e., not using every day or somedays at follow-up). The outcome ‘making a quit attempt’ is defined as a quit attempt at follow-up (vs. no quit attempt at follow-up) among current established users at baseline. Since no P30D use at baseline is defined with respect to each tobacco product, P30D use of ‘other’ tobacco products at baseline are considered as correlates of ‘making a quit attempt’ of the given tobacco product at follow-up.
GEE logistic regression analyses were used to assess correlates of making a quit attempt at follow-up among current established users at baseline over a one-year period of time (i.e., Wave 1-Wave 2 and Wave 2-Wave 3), including up to two change data points per individual and statistically controlling for the correlation among observations from the same individuals.
All correlates reflect baseline measurement for each wave pair (e.g., when evaluating change between Wave 1 and Wave 2, the age correlate reflects a person’s age at Wave 1, and when evaluating change between Wave 2 and Wave 3, the age correlate reflects a person’s age at Wave 2).
Analyses adjusted for age group, sex, race/ethnicity, sexual orientation, educational attainment, annual household income, each tobacco use correlate, and wave.
Tobacco dependence score was defined as described and validated by Strong et al. (2017). Weighted means are presented with 95% confidence intervals. To estimate odds ratios and 95% confidence intervals, the tobacco dependence variable was scaled to a mean of 0 with standard deviation of 1 for each tobacco product (therefore, ORs indicate the likelihood of the outcome per standard deviation unit increase in the level of tobacco dependence for each tobacco product).
Estimates with either a relative standard error greater than 30 or a corresponding denominator less than 50 have been suppressed.
