OR: Odds Ratio; CI: Confidence Interval
^a Mutually adjusted for group (control vs. intervention group), time (baseline vs. 12-month follow-up), and the interaction term (group × time)
^b Mutually adjusted for group (control vs. intervention group), time (baseline vs. 12-month follow-up), the interaction term (group × time), sex, age, and educational attainment
^c Mutually adjusted for group (control vs. intervention group), time (baseline vs. 12-month follow-up), the interaction term (group × time), sex, age, educational attainment, and policy awareness among employees
