Topic: Risk, prevention and care in population studies
Introduction Information on anticipated survival time after dementia diagnosis among racially/ethnically diverse patients is needed to plan for care and evaluate disparities. Methods Dementia-free health care members aged ≥64 years were followed (1/1/2000-12/31/2013) for dementia diagnosis and subsequent survival (n = 23,032 Asian American; n = 18,778 African American; n = 21,000 Latino; n = 4543 American Indian/Alaska Native; n = 206,490 white). Kaplan-Meier curves were estimated for survival after dementia diagnosis by race/ethnicity. We contrasted mortality patterns among people with versus without dementia using Cox proportional hazards models. Results After dementia diagnosis (n = 59,494), whites had shortest median survival (3.1 years), followed by American Indian/Alaska Natives (3.4 years), African Americans (3.7 years), Latinos (4.1 years), and Asian Americans (4.4 years). Longer postdiagnosis survival among racial/ethnic minorities compared with whites persisted after adjustment for comorbidities. Racial/ethnic mortality inequalities among dementia patients mostly paralleled mortality inequalities among people without dementia. Discussion Survival after dementia diagnosis differs by race/ethnicity, with shortest survival among whites and longest among Asian Americans.

Key findings
- We contrasted mortality patterns among people with versus without dementia using Cox proportional hazards models.
- Results After dementia diagnosis (n = 59,494), whites had shortest median survival (3.1 years), followed by American Indian/Alaska Natives (3.4 years), African Americans (3.7 years), Latinos (4.1 years), and Asian Americans (4.4 years).
- Longer postdiagnosis survival among racial/ethnic minorities compared with whites persisted after adjustment for comorbidities.
Why it matters
After a dementia diagnosis, white patients had the shortest survival time and Asian Americans the longest, with other groups in between. These differences mostly matched the mortality patterns seen in people without dementia, so they may reflect broader health differences rather than dementia care alone.
