Other = Common-law marriage, widowed, single, or divorced. For dichotomous variables, logistic regression was conducted. For continuous variables, COM-Poisson models have been used in the following cases: education, medications, and diagnosis; all the other cases used normal distribution. Significance: ^p < 0.1, *p < 0.05. Significant (or marginally significant) values are highlighted in bold.
