study entry. We calculated ADRD incidence by age categories for each race, and conducted multivariate Cox models on the overall sample and race strata separately, to identify risk factors. Results: 466,292 AAs and 3,769,589 WAs were included. Compared to WAs, AAs were younger, less likely to be married and to live in rural areas, and had more medical comorbidities. ADRD incidence increased by age category, ranging from 5.29 in 65-70 years old to 45.78 in 85+ years old per 10,000 person-months in AAs and 3.24 to 24.22 per 10,000 person-months in WAs. Overall, AAs had higher risk of developing ADRD than WAs (adjusted HR1⁄41.64, 95%CI1⁄41.62-1.66). Other significant risk factors included being Hispanics and not married, live in urban areas, and having medical comorbidities (including depression, stroke, and traumatic brain injury [TBI]). Several comorbid conditions were associated with reduced risk, including hypertension, hyperlipidemia, arthritis, and asthma. There was a significant interaction between gender and income with race, as AA women had a lower risk of ADRD but WA women had a higher risk; income level was associated with reduced risk of ADRD in WAs but not in AAs. Conclusions: This study included the largest cohort of US veterans aged 65+ with AAs had consistently higher risk for developing ADRD compared to WAs, regardless of age. Among risk factors, stroke and TBI had the strongest associations with ADRD. Further investigations are necessary to understand the risk and protective effects of these factors.
