Abstract

OBJECTIVE:

To identify incidence and prevalence of dementia in racial and ethnic populations in the United States.

METHODS:

A systematic review of literature.

RESULTS:

A total of 1215 studies were reviewed; 114 were included. Dementia prevalence rates reported for age 65+ years from a low of 6.3% in Japanese Americans, 12.9% in Caribbean Hispanic Americans, 12.2% in Guamanian Chamorro and ranged widely in African Americans from 7.2% to 20.9%. Dementia annual incidence for African American (mean = 2.6%; SD = 1%; range, 1.4%-5.5%) and Caribbean Hispanic populations were significantly higher (mean, 3.6%; SD, 1.2%; range, 2.3%-5.3%) than Mexican American and Japanese Americans and non-Latino white populations (0.8%-2.7%), P < .001.

CONCLUSIONS:

Data are needed for American Indian, most Asian, and Pacific Islander populations. Disaggregation of large race/ethnic classifications is warranted due to within-population heterogeneity in incidence and prevalence. African American and Caribbean Hispanic studies showed higher incidence of dementia. A nationwide approach is needed to identify communities at high risk and to tailor culturally appropriate services accordingly.
