Income data were unavailable for three participants

P-values for continuous variables were derived from GLMs.

P-values for categorical variables were derived from chi-square tests.

Note. Significant associations between variables are bolded.

Note. < College = did not complete college (bachelor) degree; College = completed college degree (bachelor) degree; Post-grad = completed master’s or doctoral degree.
