Exploring sleep quality, obesity, eating jetlag, chronotype, and Internet Gaming Disorder in early adolescents: a mixed-methods study.
Article in BMC psychology, 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
backgroundRecent research indicates that video games and screen time are directly related to children's sleep patterns and lifestyles. Uncontrolled and prolonged gaming may negatively impact sleep quality, alter meal timings, and increase the risk of obesity. The effects are more pronounced in those with an evening-type orientation. This study aims to examine the interaction among sleep quality, obesity, eating jetlag, chronotype, and Internet Gaming Disorder (IGD) in early adolescents.
methodsA total of 280 students participated in the study, aged 11-14 years, and 42.9% were female. Additionally, 6.1% of the students were classified as "disordered gamers." The research was conducted using a mixed-methods approach, with quantitative data collected through various scales: Demographic Form, Sleep Quality Scale and Sleep Variables Questionnaire, Morningness-Eveningness Scale for Children, and Internet Gaming Disorder Scale-Short Form. Qualitative data were obtained through semi-structured interviews.
resultsThe analyses reveal that IGD scores are positively associated with eating jetlag and poor sleep quality, while MESC scores are negatively associated with both IGD and sleep quality. Multiple linear regression analysis found that eating jetlag and poor sleep quality were significantly associated with IGD scores, while MESC showed a negative association. Although IGD scores showed a weak association with BMI, BMI was not a significant predictor in the regression analysis. Additionally, the three-way ANCOVA analysis indicated that sleep quality and MESC categories had significant effects on IGD scores. The IGD scores were significantly influenced by the interaction between sleep quality and MESC categories, as well as the interaction between eating jetlag and MESC categories. Qualitative findings also highlighted that evening-type individuals exhibited more irregular eating habits and unhealthy lifestyles. They emphasized the negative effects of online gaming, reported having more irregular sleep patterns, and experienced worse mood and lower energy levels in the mornings. Furthermore, it was found that they engaged in more online gaming.
conclusionsThe findings of this study indicate that IGD may be influenced by chronotype, sleep quality, and irregularities in eating patterns, suggesting a multidimensional nature.
