Data-driven approach to understand associations between dietary patterns, sleep problems, and mental health in adolescents.
Article in Sleep health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesEmerging evidence suggests a role of diet in sleep disturbances and mental health including internalizing (e.g., anxiety, depression) and externalizing (e.g., aggression, impulsivity) problems.
methodsThis study employed a data-driven approach to construct a Sleep-Mental Health-Eating Index and assessed its mediating roles in the relationships between difficulties initiating and maintaining sleep and mental health problems in 11,000 youth aged 9-10years. Difficulties initiating and maintaining sleep and mental health problems were assessed annually from baseline to Year2, and diet at Year1. The Shapley Additive Explanations analysis was used to derive the eating index.
resultsSix dietary categories emerged as important predictors of our outcomes, with whole grains, green vegetables, and berries linked to lower difficulties initiating and maintaining sleep scores, while sweet pastries, fast food, and butter cream linked to higher difficulties initiating and maintaining sleep. Dietary factors explained 2.24% of difficulties initiating and maintaining sleep variation, surpassing demographics (1.21%). For internalizing behaviors, dietary and demographic contributions were similar (1.86% vs. 1.98%). Demographics were the strongest predictors of externalizing symptoms (3.84%). Higher baseline difficulties initiating and maintaining sleep (beta = -0.026, 95% CI: -0.038, -0.015) and internalizing scores (beta = -0.027, 95% CI: -0.035, -0.019) were associated with worse eating index at Year1. Additionally, the eating index mediated relationships between baseline difficulties initiating and maintaining sleep/internalizing problems and Year2 outcomes. Overall, indirect effects range from 3.2% to 7.0%.
conclusionsThese findings highlight diet's role in predicting and mediating sleep and mental health outcomes. Healthy foods were associated with fewer sleep difficulties and internalizing problems, while unhealthy foods worsen sleep and behavior problems. Targeting diet may improve interventions addressing adolescent sleep and mental health challenges.
