a Means (Standard Deviations) are not adjusted for covariates
b Models controlled for baseline covariates including age, gender, race/ethnicity, income, education level, health literacy level, employment status, number of children, smoking status, and BMI. The 95 % confidence intervals are also adjusted to be cohort robust. Analytic procedures uses intention-to-treat last observation carried forward imputations
c L-CAT scale range: 0 = low, 5 = high
d Media literacy scale range: 19 = low, 133 = high
