Abstract:

BACKGROUND: Many older adults receive caregiving; however, less is known about how a change in a care recipient''s functional activity limitations [instrumental activities of daily living (IADL) and basic activities of daily living (ADL)] as well as their cognitive impairment influence the amount of caregiving received. METHODS: Using the Health and Retirement Study (2002-2014) we identified community-dwelling respondents with Alzheimer disease and related dementias (ADRD; n = 674), cognitive impairment no dementia (CIND; n = 530), and no cognitive impairment (n = 6126). We estimated a series of two-part regression models to identify the association between care recipients'' level of cognitive impairment, change in total number of IADL/ADL limitations and amount of caregiving received. RESULTS: Persons with ADRD received 235.8 (SD = 265.6) monthly hours of care compared with 26.0 (SD = 92.6) and 6.0 (SD = 40.7) for persons with CIND and no cognitive impairment, respectively. An increase in one IADL/ADL limitation resulted in persons with ADRD and CIND receiving 4.90 (95% confidence interval: 3.40-6.39) and 1.43 (95% confidence interval: 0.17-2.69) more hours of caregiving than persons with no cognitive impairment. Increases in total IADL/ADL limitations were associated with persons with ADRD, but not CIND, receiving more days of caregiving and having more caregivers than persons with no cognitive impairment. CONCLUSIONS: Compared with persons with no cognitive impairment, increases in IADL/ADL limitations disproportionally increases the caregiving received for persons with ADRD. Policies and programs must pay attention to functional impairments among those living with ADRD.
