A - 30 Risk Factors for Poor Sleep Quality and Subjective Cognitive Decline during the COVID-19 Pandemic in an Ethnoracially Diverse US Sample

Abstract Objective Poor sleep quality is associated with subjective cognitive decline (SCD), a risk factor for developing Alzheimer’s disease and Mild Cognitive Impairment. These relationships are understudied in ethnoracially diverse groups. We examined associations between sociodemographic characteristics, sleep changes during the COVID-19 pandemic (i.e., increased problems/poorer quality), and SCD in ethnoracially diverse older individuals in the US. Method 870 older adults (126 Latino, 74 Black, 33 Asian, and 637 White; Mage = 67.0 [7.6]) completed an online survey including sociodemographic information, the Everyday Cognition scale (ECog), which measures SCD, and a question inquiring about increased sleep problems/worsened sleep quality during the pandemic. Chi-square tests and analyses of variance assessed sociodemographic and SCD differences between groups. Regression and correlation analyses assessed relationships among sociodemographic factors, changes in sleep quality, and SCD. Results White participants were older (p
