BACKGROUND: We investigated the effect of economic assets on mortality in patients with dementia in a national cohort of elderly individuals aged 65 or older.
OBJECTIVE: To examine the effect of economic assets on mortality in patients with dementia.
METHODS: Incidence of dementia and all-cause mortality was analyzed with incidence rate ratios (IRR) in three different categories of economic assets by means of Cox regression models.
RESULTS: A total of 874,246 individuals aged 65+ were included. The risk of receiving a dementia diagnosis was highest in the low economic asset group (IRR 1.19). Patients with dementia had a higher mortality compared to those without a diagnosis (IRR 2.85). The mortality in the dementia group was lowest in the high economic asset group (IRR 3.31). However, the increase associated with dementia was lowest within the low economic assets group (IRR 2.57).
CONCLUSION: Mortality is increased with a dementia diagnosis and highest for the low economic asset group. However, the increase in mortality attributable to dementia was higher in the high economic assets group.
