N/A, not applicable; OR odds ratio.

a

Intention to quit vaping in the next 12 mo was a binary variable (yes versus no), measured by the question, “Are you seriously thinking about quitting e-cigarettes?” Those who responded “Yes, during the next 30 days,” “Yes, during the next 6 months,” and “Yes, during the next 12 months” were classified with intention to quit vaping in the next 12 mo. Weighted n (intention to quit = yes) is 1 756 000.

b

Univariate analyses were conducted by using a survey logistic regression model with “intention to quit vaping” as the outcome variable and each variable in the table as a regressor.

c

Multivariable analysis was conducted by using the survey logistic regression model with “intention to quit vaping” as the outcome variable and all covariates listed in the column as simultaneous regressors. Missing covariate data were infrequent (n range: 0–187) and managed with multiple imputation by using 20 multiply imputed data sets.

d

This association is significant.
