To estimate the prevalence and correlates of dementia at death and to assess the usefulness of death certificate data in the reporting of dementia.
The authors analyzed next-of-kin interviews for 599 male and 628 female decedents using data from the National Institute on Ag ng's Survey of the Last Days of Life.
Death certificate data in this population show the prevalence of dementia to be less than I%, consistent with previous reports based on death certificates but a substantial underestimate compared to the 1.9% reported in a national survey.
Using a dementia ndex based on the informant's report of whether the decedent had been diagnosed with a dementing illness and the extent of her or his cognitive and functional limitations, this study found a prevalence of dement of 8.5%. A high score on the dementia ndex was significantly associated with older age, Parkinson's disease, and incontinence.
Lower relative odds for dementia at death were found for people with either a lifetime history or a death certificate report of cancer.
Similarly, people with a lifetime history of coronary heart disease were found to have lower relative odds for dementia at death.
These results suggest that informant interviews may be a useful source of data to examine factors associated with dement and to estimate the prevalence of dementia in the ast year of life.
