Health Functioning Moderates the Association Between Chronic Conditions and Mental Illness in Childhood.
Article in Child: care, health and development, 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
objectivesThis study aimed to quantify associations between chronic conditions and mental illness; investigate potential moderating effects of child age, sex, health functioning, mental health service contact and household income on these associations; and explore the potential mediating effect of family functioning.
methodsThis study conducted secondary data analyses on a sample of 6242 children aged 4-17 years from the 2014 Ontario Child Health Study (OCHS). Chronic conditions were assessed using a standard list of conditions developed by the Statistics Canada. Mental illness was assessed with the Emotional Behavioural Scales (EBS). The Health Utility Index Mark III measured health functioning. Logistic regression models quantified associations between chronic conditions and mental illness. Moderating effects were tested with product-term interactions in logit models and interpreted using average marginal effects. Mediating effects were explored using the product of coefficients method.
resultsHaving a chronic condition was associated with mood disorder (OR = 2.25 [95% CI: 1.36-3.74]). For children who have better health functioning, average marginal effects indicated that children with chronic conditions are 29% more likely to have any mental illness (p < 0.01), 21% more likely to have anxiety disorders (p < 0.05) and 21% more likely to have ADHD (p < 0.05) than children with no conditions. For children who have poorer health functioning, there was no association between chronic conditions and mental illnesses. Family functioning did not mediate any associations between chronic conditions and mental illness outcomes.
conclusionThe association between chronic conditions and mental illness in children is nuanced, with health functioning moderating this association for any mental illness, anxiety disorders and attention-deficit hyperactivity disorder specifically. Mental health screening programs should ensure children with chronic conditions who have better health functioning are routinely assessed and upstream interventions initiated early to reduce the incidence of physical-mental multimorbidity.
