Insights
Children with attention deficit hyperactivity disorder (ADHD) show links between sleep problems and diet. Higher sugar intake correlated with more sleep disturbance and night sweats in this pilot study.
Area of Science:
- Pediatric Sleep Medicine
- Neurodevelopmental Disorders
- Nutritional Psychiatry
Background:
- Sleep disturbances are prevalent and impactful in children with Attention Deficit Hyperactivity Disorder (ADHD).
- Dietary factors are known to influence ADHD symptoms, but the interplay between diet, sleep, and behavior in these children is under-researched.
- Understanding these relationships is crucial for comprehensive ADHD management.
Purpose of the Study:
- To investigate the relationships between sleep patterns and dietary intake in children diagnosed with ADHD.
- To explore potential correlations between ADHD symptoms, sleep disturbance, and specific dietary components.
Main Methods:
- A pilot study involving parental reports from 88 Australian children (aged 6-13 years) diagnosed with ADHD.
- Sleep disturbance was assessed using standardized criteria (≥ 2 standard deviations above the mean).
- Dietary intake was analyzed in relation to reported sleep patterns and ADHD symptoms.
Main Results:
- Approximately 30% of children in the study experienced significant sleep disturbance.
- A significant association was found between higher ADHD symptom severity, increased sleep disturbance, and dietary intake.
- Parents reported higher carbohydrate, fat, and particularly sugar intake in children with more sleep disturbance; sugar intake predicted night sweats.
Conclusions:
- The findings suggest a notable interrelationship between diet and sleep in children with ADHD.
- Both sleep and dietary habits are potentially modifiable factors in ADHD treatment.
- Further research is warranted to elucidate these complex interactions and inform therapeutic strategies.
Abstract:
Sleep disturbances are common and consequential in children with attention deficit hyperactivity disorder (ADHD). Diet also influences ADHD symptoms. Interrelationships between diet, sleep and behaviour in children diagnosed with ADHD are little studied. We investigated, via parental report, the relationships between sleep and diet in 88 Australian children aged 6-13 years old (M = 8.94, SD = 1.78). This pilot data shows that 30 per cent of the children had sleep disturbance (≥ 2 standard deviations above the mean) with significant relationships between ADHD symptoms, sleep disturbance and diet. Parents who reported more sleep disturbance also reported a higher intake of carbohydrate, fats, and, most particularly, sugar which was also a significant predictor of night time sweating. These findings suggest an interrelationship between diet and sleep in children with ADHD. Given that both sleep and dietary intake are potentially modifiable behaviours within treatment regimes of children with ADHD, further investigation is needed.
