exclusively from cohorts of highly educated Caucasian individuals. To fill epidemiological and clinical gaps in the available information about dementia in oldest-old ethnic minorities, we established LifeAfter90. The goal of this newly established longitudinal cohort study, is to investigate lifecourse determinants of dementia incidence, cognitive decline, neuropathologic changes, and brain imaging markers in an ethnically diverse cohort of individuals aged 90 years and older (recruitment goal1⁄4800). Here we present descriptive information of the first 370 participants enrolled in the LifeAfter90 Study. Methods: LifeAfter90 participants are long-time members of the Kaiser Permanente Northern California Health Care System without a dementia diagnosis in their medical record at the time of recruitment. Evaluations in LifeAfter90 are every six months and include among others, the Everyday Cognition (ECog, a self-rated questionnaire about the ability to perform cognitive tasks), and the Geriatric Depression Scale (GDS, a self-rated questionnaire about depressive symptoms). We describe demographics and scores on the ECog and GDS by racial/ethnic groups. Results: The first 370 participants are on average 92.6 years of age (range1⁄490-104 years) and 64% are women. 30% have a highschool education or less but that percentage is higher for African Americans and Latinos (Table). The racial distribution is: 24% African American, 17% Asian, 8% Latino, 8% other/multiracial, and 43% Caucasian. In the ECog, Latinos had a lower percentage who were concerned about memory problems (Table), but had the highest average score (indicative of more impaired ability), although scores were similar across groups. In the GDS, Latinos had the highest average score and were the group with the highest proportion having a score >4 (indicative of depression). Conclusions:We introduce LifeAfter90, a first-of-its kind cohort study of oldest-old individuals where most participants are ethnic minorities. Although too early to test for differences, we have indications of potential future disparities in the way the racial ethnic/groups are reporting on their cognitive abilities and depressive symptoms, which we will explore once recruitment is complete on this lifecourse cohort of ethnically diverse oldest-old individuals.
