Adiposity and attention deficit hyperactivity disorder comorbidity in Chinese children and adolescents: the role of adiposity duration and screen time.
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
backgroundThis study aimed to investigate the environmental factors associated with attention deficit hyperactivity disorder (ADHD) in Chinese children and adolescents with adiposity (obesity or overweight).
methodsA total of 130 children and adolescents with adiposity and 130 age- and sex-matched controls with normal weight were enrolled in this cross-sectional study. Children with ADHD were identified based on International Classification of Diseases (ICD-10) codes. The severity for psychiatric and behavioral problems, ADHD symptoms, and oppositional defiant disorder was compared between the groups. Multivariable logistic regression analysis was performed to identify factors associated with the comorbidity of ADHD in children and adolescents with adiposity.
resultsThe detection rate of ADHD was significantly higher in the adiposity group compared to control group (15.4% vs. 6.2%; p = 0.016). Children and adolescents with adiposity exhibiting higher scores in learning problems, impulsivity/hyperactivity, anxiety, and hyperactivity indices. Exploratory analyses indicated a positive correlation was found between BMI percentile (BMI-P) and inattention symptoms scores in individuals with ADHD (r = 0.512, p = 0.005). Logistic regression results showed that factors associated with ADHD in children and adolescents with adiposity included prolonged adiposity duration (> 3 years) (OR = 5.61, 95% CI: 1.79–17.59, p = 0.003) and excessive screen time (> 3 h/day) (OR = 6.45, 95% CI: 1.59–26.11, p = 0.009).
conclusionsProlonged adiposity duration and excessive daily screen time were found to be associated with ADHD among children and adolescents with adiposity.
