Abstract:
We examined racial/ethnic differences in cognitive disability and the contribution of sociodemographic factors to these differences. Using logistic regression, we measured the association between race/ethnicity and cognitive disability after adjustment for sociodemographic covariates, including agegroup, sex, education, nativity, region, marital status, and occupation among 2009 American Community Survey respondents (≥25 years). Effect modification was also explored. Cognitive disability was self-reported by 6 % of respondents. The proportion with cognitive disability was highest for Blacks and Native American/Pacific Islanders. Statistically significant effect modification was observed for all sociodemographic covariates, except sex. Although most sociodemographic modifiers revealed a more convoluted relationship between race/ethnicity and cognitive disability, the cognitive benefits of higher education, foreign born nativity, and top-tier occupations were observed among most racial/ethnic groups. The observed interplay between sociodemographics and race/ethnicity highlight a complex relationship between race/ethnicity and cognitive disability. Future research should examine mechanisms for this induced complexity.
