^aModel 1 Simple logistic model, crude OR was obtained; independent variable (Y): participants with vs. without multimorbidity.

^bModel 2 was adjusted for age, employment, education, and marital status; independent variable (Y): participants with vs. without multimorbidity.

^cModel 3 was adjusted for age, employment, education and marital status; independent variable (Y): participants with multimorbidity vs. had no disease.

^dModel 4 was adjusted for age, employment, education and marital status; independent variable (Y): participants with multimorbidity vs. have one disease.
