B = coefficient, BADL = basic activities of daily living, IADL = instrumental activities of daily living, SE = standard error.
Model 1: crude model. Model 2: adjusted for age, gender, marital status, education level, smoking and drinking. Model 3: adjusted for age, gender, marital status, education level, smoking, alcohol consumption, self-rated health, chronic diseases, BADL, IADL and cognitive function.
