Area of Science:

  • Gerontology
  • Cognitive Science
  • Sociology of Health

Background:

  • Race differences in cognitive functioning among older adults remain a significant research challenge.
  • Existing literature often focuses separately on biological correlates or social inequalities.
  • This study integrates clinical and social research perspectives to understand these disparities.

Purpose of the Study:

  • To examine the direct and indirect effects of race on cognitive functioning in older adults.
  • To investigate the role of social and biological risk factors in mediating race-based cognitive differences.
  • To inform future research on cognitive aging and health disparities.

Main Methods:

  • Utilized data from the Assets and Health Dynamics of the Oldest Old survey (Wave 1).

Related Experiment Videos

  • Employed structural equation modeling (LISREL 8.30) for analysis.
  • Analyzed a total sample of 5,955 older adults.

    • Main Results:

    • Race demonstrated a direct association with cognitive functioning.
    • Indirect effects of race on cognitive functioning were observed through social risk factors, specifically education and health insurance.
    • No significant indirect effects of race were found through biological risk factors.

    Conclusions:

    • The findings underscore the importance of considering both direct and indirect pathways, particularly social determinants, through which race influences cognitive aging.
    • Further investigation into race-based differences across various dimensions of cognitive functioning and over time is warranted.
    • This research highlights the complex interplay of race, social factors, and cognitive health in later life.
