Abstract: Objective Racial/ethnic disparities in cognitive performance among older adults have been previously identified. This study’s aim was to examine the cognitive performance between diverse Hispanic and White non-Hispanic (WNH) older adults with similar functional performance. Method Groups were stratified by Clinical Dementia Rating scale (CDR) global score, as follows: (1) CDR score = 0 (n = 77; 70.1% female; Mean ± SD age = 70.9± 6.3 yrs; education = 17.4±9.9 yrs; MMSE = 28.95± 1.48); (2) CDR score = 0.5 (n = 179; 58.1% female; age = 74.0± 8.1 yrs; education = 16.0 ± 9.5 yrs; MMSE = 27.50 ± 2.5); (3) CDR Score = 1.0 (n = 41; 61% female; age = 73.7 ± 9.7 yrs; education = 16.7 ± 13.6 yrs; MMSE = 23.2 ± 3.8). A series of One-Way Analysis of Covariance (ANCOVA) were conducted comparing Hispanic to WNH, with age and education as covariates. Results Among the CDR = 0 group, WNH performed significantly better than Hispanics on Trails-A [F(1,69) = 8.59, p < .01], Trails B [F(1,69)=4.166, p < .05], COWAT [F(1,73)=14.79, p < .001], and Category Fluency [F(1,73)=9.91, p < .01]; findings were not significant for logical memory (p=.157), or HVLT (p=.494) delayed. Among participants with CDR of 0.5, WNH performed significantly better than Hispanics on Trails B [F(1,166)=5.83, p < .05]. Among participants with CDR of 1, there were no significant differences. Conclusion Among older adults with similar levels of functioning, Hispanics performed worse on measures of processing speed, executive function, and verbal fluency. Future studies should evaluate the contribution of level of acculturation, social engagement and exercise to differences in cognitive scores among individuals with similar functional performance.
