Processed Food Consumption and Sleep Quality in School-Aged Children: Insights from a Cross-Sectional Study.
Article in Nutrients, 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
objectiveThis cross-sectional study aimed to investigate the association between processed food consumption and sleep quality among school-aged children.
methodsOur sample consisted of 137 children, with 52.6% being girls with a mean age of 7.9 ± 1.2 years. Moreover, 40.2% of children had overweight and 35.9% had experienced sleep problems. Dietary intake was evaluated using two non-consecutive 24 h recalls, and foods were categorized according to the NOVA classification system. The amount of sweet snacks consumed, in grams, was recorded for each meal and throughout the day. Sleep quality was assessed using the Portuguese Children's Sleep Habits Questionnaire (CSHQ-PT).
resultsThe study found a significant and positive association between the sleep habits score and daily sweet snack consumption (B = 0.035; 95% CI: 0.011, 0.059). Additionally, there were higher odds of experiencing sleep problems in those children who consumed a higher percentage of energy from ultra-processed foods (OR: 1.043; 95% CI: 1.004, 1.084), higher total daily consumption of sweet snacks (OR: 1.016; 95% CI: 1.006, 1.026), particularly during morning and afternoon snack times (OR: 1.018; 95% CI: 1.002, 1.033).
conclusionsThese findings underscore the importance of addressing dietary patterns on children's sleep quality. Future interventions should account for reducing NOVA 4 and sweet snack consumption in order to improve sleep quality.
