Data are shown as estimated mean with 95% confidence intervals. Ref, Reference

^aModel 1: Baseline variables of age, sex, and body mass index were adjusted

^bModel 2: Further adjusted for smoking transition, baseline alcohol consumption, 5-year changes in alcohol consumption, baseline sleep duration, changes in the sleep duration, baseline weekly exercise duration during leisure, 5-year changes in the exercise duration, occupational physical activity transition, job position transition, shift work transition, and overtime work transition
