Abstract

Abstracts
Little is known about the impact of daily experiences of interpersonal discrimination on cognition among adults across the lifecourse. The Midlife in the United States-II Study (n = 3,470) data was used to examine associations between discrimination and executive functioning (EF) and whether associations differ by age. A telephone-based neurocognitive assessment index assessed EF with higher scores representing better cognition. The mean EF Z-score for the lowest discrimination quartile was 0.16 and -0.01 for the highest quartile (p<0.001). Discrimination in the highest quartile was associated with a -0.10 decrease in EF, adjusting for age, education, financial situation, sex, race, smoking status, BMI, and depressive symptomology. Higher discrimination was associated with decreases in EF z-score of -0.19 (p< 0.001) among those aged 20–44 and -0.15 among those 45–64 (p<0.01). No significant associations were found among those ≥ 65 years. Findings demonstrate discrimination noxiously influenced EF, particularly among younger and middle-aged adults.
