Note: Based on 7,622 Medicare beneficiaries age 65 and older, alive during the calendar and had positive total healthcare expenditures. The regression models controlled for sex, age, race/ethnicity, marital status, education, poverty status, Medicaid, private insurance, prescription drug coverage, number of chronic conditions, perceived physical health, functional status, body mass index, and current smoking.

ADRD: Alzheimer’s disease and related dementias; Prob: Probability; SE: Standard error; Sig: Significance; Wt: Weighted.
