Sleep May Suffer in Blacks Who Face Discrimination | DiversityInc – Between 2000 and 2004 and again between 2008 and 2012, study participants completed the Modified Williams Everyday Discrimination Scale, a questionnaire that asks about the frequency of experiences with everyday mistreatment. For example: How often on a day-to-day basis do you have the following experiences: being treated with less courtesy; being treated with less respect; do people act as if you are dishonest?
Participants also reported their sleep duration and rated their sleep quality from 1 (poor) to 5 (excellent).
At the start, the participants were 55 years old on average, about two-thirds were women, and about 55 percent reported that they slept no more than six hours a night.
From the beginning, discrimination and sleep quality were linked. The association remained constant over time, the research team found.
Compared to participants who reported low levels of discrimination, participants who reported higher levels had 43 percent higher odds of short sleep, they slept 15 minutes less on average per night and they had lower sleep quality scores.
