Influence of Sleep Time on the Consumption of Ultra-Processed Foods in Adolescents in a Capital of Brazil: A Longitudinal Study.
Article in Nutrients, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
BACKGROUND/
objectivesThe study prospectively assessed the association between sleep duration and the consumption of ultra-processed foods in adolescent students from a Brazilian capital.
methodsWe observed 1431 adolescents participating in the Longitudinal Study on sedentary behavior, physical activity, dietary habits, and adolescent health, aged 10 to 14 years, in the years 2014 to 2017. The percentage of consumption of ultra-processed foods was evaluated by the Friedman test. Generalized Estimation Equation (GEE) models with parameters for robust analysis were used to verify the prospective association between sleep and the consumption of ultra-processed foods.
resultsThe percentage consumption of ultra-processed foods in relation to total daily calories increased in boys between 15 and 17 years old (31.8% in 2015 to 35.8% in 2017), being more stable among older girls (36.7% in 2015 to 37.7% in 2017), which may have occurred due to the influence of the social environment, reduced critical capacity, and lower concern for nutrition. This excessive consumption can lead to health and body composition impairments. Over time, adolescents who were in the fourth quartile of sleep had a 1.4% reduction (95% CI -2.49; -0.28) in the energy percentage from ultra-processed foods. When adjusting the initially used model in the GEE (Generalized Estimation Equation) with sociodemographic variables (income, maternal education, age) and lifestyle factors, sleep duration decreased by 2.1% (95% CI -4.09; -0.22) only in boys. The shorter duration of sleep in adolescents has been shown to be associated with unhealthy behavioral factors, such as a preference for fatty and sugary foods. There were no statistically significant associations for girls in this model.
conclusionsSleep influences the consumption of ultra-processed foods in adolescents, showing that as sleep time increases, the consumption of foods classified as ultra-processed decreases.
