The authors' aims were to estimate the odds of diagnosed ADRD among US- and foreign-born racial/ethnic groups compared to US-born White older adults and make comparisons by nativity within each racial/ethnic group. Diagnosed ADRD was determined using ICD-9 or ICD-10 billing codes created from self-reports during MEPS household interviews. US-born Black, Hispanic, and foreign-born Hispanic older adults, but not foreign-born Black or Asian older adults, had higher odds of diagnosed ADRD compared to US-born White older adults after adjusting for age and sex. After additional adjustment for education, health insurance, usual source of care, and chronic conditions, only US-born Black older adults continued to show higher odds of diagnosed ADRD compared to US-born White older adults. There were no differences in ADRD diagnosis by nativity within each racial/ethnic group. Findings highlight the need for including nativity in studies comparing racial/ethnic groups to Whites to fully capture the ADRD burden among US-born Black older adults.
