Note: Boldface indicates statistical significance compared to reference group using t-test (p < 0.05).
Separate multivariable logistic regression models were run for each influenza vaccination hesitancy question for a total of four individual models. The outcome variable is receipt of early-season influenza vaccination by mid-November 2018.
The model adjusted for sex, age, race/ethnicity, marital status, education level, employment status, annual household income, having a usual place to go when sick, had high-risk conditions for influenza complications, having health insurance, and metropolitan statistical area status.
