Frequency of vaping quit attempts in the past 12 mo was measured by 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?” Among those who responded ≥1 vaping quit attempt in the past 12 mo, the frequency of vaping quit attempts was determined by “1 times,” “2 times,” “3 to 5 times,” (recoded = 4) “6 to 9 times,” (recoded = 7.5) and “10 or more times” (recoded=10), with the range of 1 to 10.
Univariate analyses were conducted by using a survey regression model with “frequency of vaping quit attempt” as the outcome variable and each variable in the table as the independent variable.
Multivariable analysis was conducted by using the survey regression model with “frequency of 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.
This association is significant.
