Older Black and White adults show cognitive function differences. This study explored if health and literacy explain these disparities in cognitive test scores.

Area of Science:

  • Gerontology
  • Cognitive Science
  • Health Disparities Research

Background:

  • Existing research indicates lower cognitive function test scores in older Black and Latino adults compared to older White adults.
  • However, the underlying reasons for these score differences remain under-examined.
  • This gap highlights the need for comprehensive investigations into contributing factors.

Purpose of the Study:

  • To evaluate the extent to which health and socioeconomic indicators explain cognitive function score differences.
  • Specifically, to assess the role of literacy level in these disparities.
  • To provide a more nuanced understanding of cognitive aging across racial groups.

Main Methods:

  • Comparative analysis of cognitive function test scores.

  • Inclusion of health indicators as potential explanatory variables.
  • Assessment of socioeconomic factors, with a focus on literacy levels.

    • Main Results:

    • Analysis revealed that differences in health and socioeconomic indicators, including literacy, partially explain score variations.
    • The study quantifies the contribution of these factors to observed cognitive differences.
    • Specific indicators were identified as significant contributors to the disparities.

    Conclusions:

    • Health and socioeconomic factors, particularly literacy, play a role in cognitive function score differences between older Black and White adults.
    • Addressing these disparities may involve interventions targeting health and literacy.
    • Further research is warranted to explore additional contributing factors and develop targeted interventions.
