Extreme racism-related events and poor sleep in African-American women.

RATIONALE

Much of the research linking racism-related stressors to poor health has focused on fairly non-violent forms of racism that directly impact individuals under study. Exposure to particularly extreme and/or violent racist events are increasingly visible via smartphone recordings and social media, with consistent anecdotal reports of the effects of seeing and hearing about these events on sleep among minorities who racially identify with the victims.

OBJECTIVE

This study examines whether exposure to direct and vicarious racism-related events (RREs), including more extreme events, are associated with sleep quality. Additionally, we examine effects of less and more violent direct RREs and vicarious RREs witnessed in person and via social media.

METHODS

Among 422 African-American women, we assessed exposure to RREs using a modified version of the Race-Related Events Scale and assessed sleep quality using the Pittsburgh Sleep Quality Index (PSQI). Linear regression analyses were used to model continuous global sleep.

RESULTS

Direct (β = 0.24 [95% CI: 0.13, 0.35]) RREs were associated with worse continuous global sleep quality scores in analyses adjusted for sociodemographics and risk factors for poor sleep. More violent direct RREs (β = 0.59 [95% CI: 0.30, 0.89]) had stronger associations with poor sleep quality than less violent direct RREs (β = 0.25 [95% CI: 0.11, 0.40]). Vicarious RREs overall (β = 0.04 [95% CI: 0.14, 0.21]) and those witnessed via social media (β = -0.07 [95% CI: 0.29, 0.14]) were not associated with global sleep quality; conversely, vicarious RREs witnessed in person were (β = 0.52 [95% CI: 0.21, 0.83]).

CONCLUSION

Extreme, direct experiences of racism, particularly those that are violent in nature, are associated with poor sleep quality. However, extreme vicarious experiences are not-- unless witnessed in person.
