Dementia Is Associated With Earlier Mortality for Men and Women in the United States

Sociodemographic trends in the United States may influence future dementia-associated mortality, yet there is little evidence about their potential impact. The study objective was to estimate the effect of dementia on survival in adults stratified by sex, education, and marital status. Methods: Using survey data from the Health and Retirement Study (HRS) linked to Medicare claims from 1991 to 2012, the authors identified a retrospective cohort of adults with at least one International Classification of Diseases—ninth revision—Clinical Modification (ICD-9-CM) dementia diagnosis code (n = 3,714). For each case, the authors randomly selected up to five comparators, matching on sex, birth year, education, and HRS entry year (n = 9,531), and assigned comparators the diagnosis date of their matched case. The authors estimated a survival function for the entire study population and then within successive strata defined by sex, education, and marital status. Both sex and level of education moderate the relationship between dementia diagnosis and length of survival.
