Associations of Sleep Health and Metabolic Syndrome Severity in Black Individuals: The Jackson Heart Sleep Study.
Article in The Journal of clinical endocrinology and metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
contextThe influence of sleep and circadian-related factors on metabolic outcomes among Black Americans are under-studied, despite the disparities in both metabolic and sleep health in this population.
objectiveThis work aimed to investigate the relationship between domains of sleep and metabolic dysfunction severity in Black individuals.
methodsWe conducted a cross-sectional analysis of the Jackson Heart Sleep Study (2012-2016), using logistic regression to assess the associations between actigraphy parameters (sleep timing, duration and regularity, continuity) and severe metabolic syndrome (MetS), defined as the highest tertile of a validated sex-, race-, and ethnicity-specific MetS severity Z score. Models were adjusted for age, socioeconomic factors, physical activity, smoking, alcohol use, and moderate to severe obstructive sleep apnea.
resultsAmong 754 participants (mean age 63 ± 11 years, 66% women, mean body mass index 31.8 ± 6.8), mean sleep onset was 23:10 ± 1:24 (hh:mm), mean sleep duration was 6.7 ± 1.1 hour, median sleep maintenance efficiency was 88.9% (interquartile range [IQR], 85.7-91.5), and median sleep fragmentation index was 28.3% (IQR, 23.2-34). In adjusted models, each 1-hour later in mid-sleep time was associated with 14% (95% CI, 1.01-1.30) higher odds of severe MetS and each 1-hour increase in sleep duration variability was associated with 34% (95% CI, 1.01-1.77) higher odds. Each 1% decrease in sleep maintenance efficiency was associated with 5% (95% CI, 0.92-0.98) higher odds of having severe MetS, and each 1% increase in sleep fragmentation index was associated with 2% (95% CI, 1.01-1.04) higher odds.
conclusionLater sleep timing, irregular sleep duration, and poor sleep continuity were associated with more severe metabolic dysfunction in Black individuals, highlighting the importance of sleep health, beyond sleep duration, on metabolic health.
