Abstract

The present study examined differences in cognitive performance of African American and European American older adults on cognitive and intellectual measures, and the extent to which literacy status or reading level was useful in explaining these group differences. African American elders performed more poorly than European American elders on 12 of 13 cognitive tests administered, p < .05. After controlling for reading level achievement, differences in performance became nonsignificant for 5 of these 12 tests. Nonetheless, some differences persisted, suggesting that other potential mediators of race differences remain to be explored in future research.

Are racial disparities in health conditional on socioeconomic status?

Melissa M Farmer, Kenneth Ferraro (2005)

Racial health inequality is related to socioeconomic status (SES), but debate ensues on the nature of the relationship. Using the US National Health and Nutrition Examination Survey I and the subsequent follow-up interviews, this research examines health disparities between white and black adults and whether the SES/health gradient differs across the two groups in the USA. Two competing mechanisms for the conditional or interactive relationship between race and SES on health are examined during a 20-year period for black and white Americans. Results show that black adults began the study with more serious illnesses and poorer self-rated health than white adults and that the disparity continued over the 20 years. Significant interactions were found between race and education as well as race and employment status on health outcomes. The interaction effect of race and education showed that the racial disparity in self-rated health was largest at the higher levels of SES, providing some evidence for the "diminishing returns" hypothesis; as education levels increased, black adults did not have the same improvement in self-rated health as white adults. Overall, the findings provide evidence for the continuing significance of both race and SES in determining health status over time.
