SES, socioeconomic status; CI, confidence interval.

Model 1 adjusted for age, sex, marital status.

Model 2 adjusted for model1 + prevalent comorbidities (including hypertension, diabetes, cardiovascular disease, cancer, and chronic bronchitis, emphysema, or chronic obstructive pulmonary disorder) and family history of the diseases (including hypertension, diabetes, and cardiovascular disease).

Model 3 adjusted for model 2 + BMI.

Model 4 adjusted for model 3 + healthy lifestyle score.

*Trend chi-square was used to test trending on Hazard ratios between high SES, medium SES, and low SES in four models (all p <0.05).

Bias-corrected percentile method was presented based on 2,000 bootstrap samples.
