Anticipating Racism is Associated with Poorer Sleep Among Adults Racialized as Black.
Article in Journal of racial and ethnic health disparities, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionRacism has deleterious effects on sleep. Higher interpersonal discrimination is associated with lower sleep duration and poorer sleep quality (i.e., poor sleep) in adults who are racialized as Black, but this association is understudied across the age range of the adult lifespan. Here, we hypothesized higher racism-related vigilance is associated with poorer sleep quality and lower sleep duration in women and men.
methodWe used a subsample of the Offspring Study of Racial and Ethnic Disparities of Alzheimer's Disease, a community-based cohort study. In adults across the lifespan racialized as Black (n = 258, 62% women, mean age = 56, SD = 11, range: 27-89), we measured the frequency of racism-related vigilance with a questionnaire on a scale from (1) at least once a week to (6) never. We measured sleep duration and sleep quality with a modified version of the Pittsburgh Sleep Quality Index and evaluated associations between vigilance and sleep with linear regression models.
resultsHigher racism-related vigilance was associated with poorer sleep quality. We observed associations between higher vigilance and lower sleep duration across the full sample, and these associations were similar among women and men.
conclusionAnticipatory experiences of racism are associated with poorer sleep quality. Specifically, the threat of racist experiences is associated with poorer sleep quality in women and men. Future research and policies should aim to reduce racism-related vigilance by intervening on negative environments that trigger vigilance responses to improve sleep quality in adults racialized as Black.
