*Model 1: unadjusted, Model 2: adjusted for age, sex, race, education, family poverty-income ratio, serum cotinine concentrations, physical activity and heavy alcohol drinking, Model 3: adjusted for the same set of variables as in Model 2 plus coexistence of the number of chronic conditions (including hypertension, diabetes, coronary heart disease, stroke, arthritis, asthma, chronic bronchitis, chronic kidney disease and cancer).
