Boldface represents statistically significant results

NH Non-Hispanic, HS High school, D/S/W Divorced/Separated/Widowed

^aNo quadratic effects of time were found at both univariate (OR 1.00; CI 0.88 – 1.13) and multivariate (OR 1.00; CI 0.87 – 1.14) level models

^bFor reversion analysis, the “less harmful” level of risk perception was used as the referent category

^cMarital status of Wave 1 has been extrapolated from the marital status of Wave 2 due to unavailability in the survey

^dMultivariable results are based on 1693 observations from 1063 unique participants, and represent an analysis with all listed variables simultaneously in the model

^†Marginally significant at P = 0.0672
