Insights
Children with fragmented sleep show poorer neurobehavioral functioning (NBF) and more behavior problems. This highlights the critical link between sleep quality and cognitive and behavioral regulation in childhood development.
Area of Science:
- Child Development
- Neuroscience
- Sleep Science
Background:
- Sleep is crucial for cognitive and behavioral development in children.
- Understanding the relationship between sleep quality and neurobehavioral functioning (NBF) is essential for identifying potential developmental issues.
Purpose of the Study:
- To investigate the associations between sleep quality and NBF in school-aged children.
- To explore the impact of sleep fragmentation on cognitive performance and behavior.
Main Methods:
- 135 healthy school children (grades 2, 4, 6) participated.
- Sleep was objectively monitored using actigraphy for 5 consecutive nights.
- Neurobehavioral functioning (NBF) was assessed using a computerized system and parent-reported behavior checklists.
Main Results:
- Significant correlations were found between sleep quality and NBF, especially in younger children.
- Children with fragmented sleep exhibited lower performance on complex NBF tasks.
- Fragmented sleep was associated with higher rates of reported behavior problems.
Conclusions:
- Sleep quality is closely associated with neurobehavioral functioning and behavior regulation in children.
- These findings underscore the importance of adequate sleep for healthy child development.
- Further research is needed to understand the developmental and clinical significance of these associations.
Abstract:
The aim of this study was to examine the associations between sleep and neurobehavioral functioning (NBF) in school-age children. These variables were assessed for 135 unreferred, healthy school children (69 boys and 66 girls), from second-, fourth-, and sixth-grade classes. Objective assessment methods were used on the participants in their regular home settings. Sleep was monitored using actigraphy for 5 consecutive nights; and NBF was assessed using a computerized neurobehavioral evaluation system, administered twice, at different times of the day. Significant correlations between sleep-quality measures and NBF measures were found, particularly in the younger age group. Children with fragmented sleep were characterized by lower performance on NBF measures, particularly those associated with more complex tasks such as a continuous performance test and a symbol-digit substitution test. These children also had higher rates of behavior problems as reported by their parents on the Child Behavior Checklist. These results highlight the association between sleep quality, NBF, and behavior regulation in child development; and raise important questions about the origins of these associations and their developmental and clinical significance.
