Note: All models include the individual-level covariates age, gender, race/ethnicity, household income, experience taking tobacco-related surveys, sample source (KP or SSI), cigarette addiction, presence of household smokers, daily television hours, presence of children in household, self-reported chronic medical condition and self-reported mental health condition. All models also include the state and media market-level covariates 2010 state per capita tobacco program funding, 2012 state cigarette excise taxes, media market population size, media market median income and proportion of media market with educational attainment of bachelor's degree or higher.
