Abstract

OBJECTIVE: Impulsivity and inattention related to attention deficit hyperactivity disorder (ADHD) may increase food intake and, consequently, weight gain. However, findings on the association between obesity/overweight and ADHD are mixed. The authors conducted a meta-analysis to estimate this association. METHOD: A broad range of databases was searched through Aug. 31, 2014. Unpublished studies were also obtained. Study quality was rated with the Newcastle-Ottawa Scale. Random-effects models were used. RESULTS: Forty-two studies that included a total of 728,136 individuals (48,161 ADHD subjects; 679,975 comparison subjects) were retained. A significant association between obesity and ADHD was found for both children (odds ratio=1.20, 95% CI=1.05-1.37) and adults (odds ratio=1.55, 95% CI=1.32-1.81). The pooled prevalence of obesity was increased by about 70% in adults with ADHD (28.2%, 95% CI=22.8-34.4) compared with those without ADHD (16.4%, 95% CI=13.4-19.9), and by about 40% in children with ADHD (10.3%, 95% CI=7.9-13.3) compared with those without ADHD (7.4%, 95% CI=5.4-10.1). The significant association between ADHD and obesity remained when limited to studies 1) reporting odds ratios adjusted for possible confounding factors; 2) diagnosing ADHD by direct interview; and 3) using directly measured height and weight. Gender, study setting, study country, and study quality did not moderate the association between obesity and ADHD. ADHD was also significantly associated with overweight. Individuals medicated for ADHD were not at higher risk of obesity. CONCLUSIONS: This study provides meta-analytic evidence for a significant association between ADHD and obesity/overweight. Further research should address possible underlying mechanisms and the long-term effects of ADHD treatments on weight in individuals with both ADHD and obesity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ADHD has high comorbidity.

    “ADHD has high comorbidity [44,45].”

    From A Female-Specific Treatment Group for ADHD—Description of the Programme and Qualitative Analysis of First Experiences (2024) · cites this paper as [44]

    The Results report that obesity is more prevalent in people with ADHD than in those without it, and the Discussion calls depression a common ADHD comorbid condition. The paper supports these specific examples, but does not establish the broader claim that ADHD has high comorbidity overall. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • There is an association between Attention Deficit Hyperactivity Disorder (ADHD) and obesity.

    “Neuropsychological testing may also be indicated if a diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) is suspected, as there is an association between ADHD and obesity (73).”
  • Clinical guidelines increasingly recommend that assessments of diet, physical activity, and health risk behaviours be used alongside anthropomorphic/blood markers of metabolic status.

    “This concept is now reflected in clinical guidelines, which are increasingly recommending that assessments of diet, physical activity and health risk behaviours are be used alongside the anthropomorphic/blood markers of metabolic status, 101 to more fully capture current physical health and future risk.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
