Notes: n = unweighted sample size; Analyses incorporate wave 4 survey weights for the longitudinal sample; OR = odds ratio; AOR = adjusted odds ratio; 95% CI = confidence interval; Sample sizes may vary due to missing data; All adjusted analyses control (all variables were treated as time-varying) for race, Hispanic ethnicity, respondent’s age, past-year income, education level, and wave of survey (i.e., Wave 3 or Wave 4).
