Racial Differences in Self-Reported Sleep Continuity Disturbance, Problem Endorsement, and Daytime Dysfunction Among Black and White Non-Hispanic Adults in the United States

Findings suggest that Black non-Hispanics experience less restorative sleep, which can lead to impaired cognitive function, mood disturbances, and increased risk of chronic illness. Observed differences in TST may be due to the unmeasured effects of EMA or to reduced time in bed, underscoring the importance of comprehensive approaches to understanding sleep disturbances like insomnia. Addressing insomnia severity using multidimensional approaches and with targeted interventions, such as Cognitive Behavioral Therapy for Insomnia and/or systematic sleep extension, could help improve sleep health. Moreover, examining differences in sleep across sociodemographic characteristics leads to nuanced understandings that highlight the importance of developing targeted, precision-based behavioral health interventions.
