Prior-night sleep duration and the relationship to quality of life and educational context in Norwegian pre-adolescents.
Article in BMC pediatrics, 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
purposeSufficient sleep is associated with improved development, health, and quality of life (QoL). The aim of this paper is twofold: (1) to describe prior-night sleep duration according to sleep recommendations across socioeconomic status (SES), age, gender and screen time use among Norwegian pre-adolescents and (2) to explore the association between reported prior-night sleep duration with QoL and school factors stratified by gender.
methodsCross-sectional data was aggregated from the Norwegian Ungdata Junior Survey, collected in 2024. In total, 45,185 children aged between 10 and 12 years provided self-reported data anonymously by filling out an electronic/online questionnaire during school hours.
resultsAbout half of the study sample (53.1%) reported adherence to international sleep recommendations for children aged 10 to 12 years, with somewhat higher adherence among boys than girls(54.5% vs. 51.8%, p < 0.01). Results from binary regressions revealed positive associations related to QoL and school factors among children adhering to sleep recommendations compared to ones not adhering, with adjusted odds ratio ranging from 1.33 to 1.79 (all p < 0.01).
conclusionsIn this population-based sample of Norwegian children aged 10 to 12 years, approximately half reported not achieving the recommended 9 to 12 h of sleep per night. Reporting prior-night sleep duration in accordance to the international sleep recommendations were strongly associated with higher QoL and positive school related factors among boys and girls, but particularly strong among girls. These findings emphasize the vital role of adequate sleep among pre-adolescents for QoL and optimizing school contexts, offering valuable insight for future practice and policy.
