Model 1: adjusted PR obtained with controlling for age.

Model 2: adjusted PR obtained with controlling for age, sex, education, and employment.

Model 3: adjusted PR obtained with controlling for covariates in Model 2 and obesity (yes versus no).

Model 4: adjusted PR obtained with controlling for covariates in Model 3 and smoking status (current or former smoker versus never smoked), physical inactivity (yes versus no), and binge drinker (yes versus no).

Model 5: adjusted PR obtained with controlling for covariates in Model 4 and frequent mental distress (≥14 days versus <14 days).
