Abstract
Objective: The objective of this study was to assess the relationship of disability (activities of daily living [ADL] and instrumental ADL [IADL]), self-rated health (SRH), and 6-year mortality with co-existing impairments in vision (self-rated), hearing (self-rated), and/or cognition (Short Portable Mental Status Questionnaire) in older adults. Method: The study sample comprised of 3,871 participants from the North Carolina Established Populations for Epidemiologic Studies of the Elderly study (NC EPESE). Results: Persons with all three impairments had increased odds of ADL/IADL disability and low SRH. Participants with combined visual and cognitive impairments had increased odds of mortality. Whereas sensory impairments were associated with poor SRH, cognitive impairment was not unless both sensory impairments were present. Conclusion: Co-existent sensory and cognitive impairments were associated with higher risk of impaired functional status. Self-rated auditory impairment alone was not associated with higher odds of death, but mortality was linked to visual and, particularly, cognitive impairment, alone or combined.
