Abbreviations: CI, confidence interval; CVH, cardiovascular health; OR, odds ratio.
a
Model 1: Unadjusted.
b
Model 2: Adjusted for demographic factors of weighted age quartiles, sex, race/ethnicity, education level, and family income-to-poverty ratio category.
c
Model 3: Adjusted for social and clinical factors of depression status, binge alcohol use, and prescription sleep aid use.
d
Model 4: Fully adjusted model including factors from Models 2 and 3.
