IADL: instrumental activities of daily living, BADL: basic activities of daily living, OR: odds ratio, CI: confidence interval, d.f.: degree of freedom
* : Adjusted odds ratio for age, sex, mobility score, comorbidity, visual and hearing impairments, urinary incontinence, self-rated health, depressive mood, and cognitive function at baseline.
