Note. All models controlled for marital status, education, health behavior (smoking and drinking status, physical activities), self-reported health, comorbidities, and household size. PIR = poverty income ratio. PR = prevalence ratio. CI = 95% confidence intervals. Variations in observations are because of missing values for some control variables.
