Model 1: Independent variable of interest.
Model 2: Model 1+demographic covariates (age, gender, education, marital status).
Model 3: Model 2+behavioural covariates (exercise, smoking, drinking, daily sleeping time).
Model 4: Model 3+occupational covariates (profession, shift work, level of hospital, work department, professional title, years of work experience, weekly working time).
The bold values represent statistically significant ORs and 95% CIs.
