a

Vaping quit attempt in the past 12 mo was a binary variable (yes versus no), measured by responding ≥1 time to the question, “During the past 12 months, how many times have you stopped using e-cigarettes for one day or longer because you were trying to quit using e-cigarettes for good?” with response options, “I did not try to quit during the past 12 months,” “1 time,” “2 times,” “3 to 5 times,” “6 to 9 times,” and “10 or more times.” Weighted N (past-year quit attempt = yes) is 2 215 000.

b

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

c

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

d

This association is significant.
