Not Just Time on Social Media: Experiences of Online Racial/Ethnic Discrimination and Worse Sleep Quality for Black, Latinx, Asian, and Multi-racial Young Adults.

Sleep quality in young adulthood sets the stage for long-term health. Racial/ethnic sleep disparities between White college-attending young adults and college-attending young adults of color exist. The stress of experiencing racial/ethnic discrimination makes it difficult for college-attending young adults of color to get good quality sleep. Yet it remains unclear if experiencing online racial/ethnic discrimination also has consequences for sleep quality, and if this association may vary by frequency of social media use. To investigate the role of racial/ethnic discrimination on sleep quality, we conducted an online survey of 154 college-attending young adults (Mage = 19.51) who identified as Black (42.2%), Latinx (16.9%), Asian (20.8%), or Bi-/multi-racial (20.1%) from a predominantly White university. Results indicated that more exposure to racial/ethnic discrimination was associated with worse sleep quality for young adults of color. Results suggest that online racial/ethnic discrimination has a similar negative impact on sleep quality regardless of the frequency of social media use. Increased attention to negative race-related experiences online as one potential risk factor for poor long-term health for young adults of color is needed, regardless of how many hours they spend on social media. Structural interventions, screening for stress due to exposure to online racial/ethnic discrimination, and facilitating opportunities to prepare for this exposure may be an important priority for sleep health and reduction of racial/ethnic health disparities.
