Insights
Frequent nightmares in children are linked to behavioral issues and comorbid sleep problems like insomnia. Parental nightmares and lower family income also correlate with children's frequent nightmares.
Area of Science:
- Pediatric Sleep Medicine
- Child Psychology
- Behavioral Science
Background:
- Frequent nightmares in children are a common concern.
- Understanding their prevalence and associated factors is crucial for effective intervention.
Purpose of the Study:
- To investigate the prevalence, correlates, and familial aggregation of frequent nightmares in children.
- To examine the association between frequent nightmares and parent-reported behavioral and mood problems.
Main Methods:
- Cross-sectional study involving 6359 children and their parents.
- Data collected on sociodemographics, sleep, behavior, and family factors.
- Multinomial regression analysis used to identify associations.
Main Results:
- Prevalence of frequent nightmares (≥1/week) was 5.2%.
- Associated factors include family income, parental nightmares, insomnia, parasomnia, and daytime consequences.
- Frequent nightmares linked to hyperactivity, temper outbursts, and poor academic performance.
- Comorbid insomnia in children with nightmares increased odds of hyperactivity and mood disturbance.
Conclusions:
- Frequent nightmares in children are associated with child, sleep, and family factors, including parental history and socioeconomic status.
- Comorbid sleep problems like insomnia and parasomnia are significant correlates.
- Frequent nightmares are independently associated with emotional and behavioral problems in children.
Study Objectives:
To conduct a systematic investigation on the prevalence, correlates, and familial aggregation of frequent nightmares in children, and to scrutinize the associations between frequent nightmares and parent-reported behavioral and mood problems in children.
Design:
A cross-sectional study was conducted by collecting the data on sociodemographic, sleep, behavioral, and family-related information from a total of 6359 children (age: mean [SD]=9.2 [1.8] years; girls: 49.9%) and their reported biological parents.
Setting:
Community.
Interventions:
N/A.
Measurements And Results:
Prevalence of frequent nightmares with a criterion of at least once per week was 5.2%. Multinomial regression analysis indicated that monthly family income, paternal and maternal nightmares, insomnia symptoms, parasomniac symptoms, and daytime consequences were significantly associated with nightmares in children. Frequent nightmares in children were significantly associated with hyper-activity (odds ratio [OR]=1.68, 95% CI 1.16-2.44), frequent temper outbursts/mood disturbance (OR=1.76, 95%CI 1.27-2.44), and poor academic performance (OR=1.62, 95% CI 1.11-2.36), after controlling for potential confounding factors. Approximately 20% of children with frequent nightmares experienced comorbid frequent insomnia. Comorbid nightmares and insomnia were associated with increased odds of hyperactivity (OR=4.13, 95% CI 2.13-8.00) and frequent temper outbursts/mood disturbance (OR=2.41, 95%CI 1.27-4.60).
Conclusions:
Frequent nightmares in children are associated with a constellation of child-, sleep-, and family-related factors, including comorbid sleep problems, such as insomnia and parasomnia, family economic status, and parental predisposition. Frequent nightmares are independently associated with emotional and behavioral problems in children.
