Background:
Sleep plays an important role in children's behavior, emotional control, and cognitive development. There is a higher prevalence of sleep problems in children with neurodevelopmental disorders (NDDs) compared to those without disease. There are a few studies regarding sleep problems among Thai preschoolers with NDDs. This study examined sleep problems in preschoolers with NDDs, compared with typically developing children (TD), and studied the association between sleep problems and behavioral problems among preschoolers with NDDs.
Methods:
Sleep problems in 140 children aged 2 to 6 years with NDDs; autism spectrum disorders, attention deficit/hyperactivity disorder, global developmental delay, and developmental language disorder were evaluated by using the Thai version of Japanese Sleep Questionnaire for Preschoolers (TH-JSQ-P) and compared with 285 TD children at the same age. Behavioral problems in the NDDs group were evaluated by using the Child Behavioral Checklist (CBCL). Sleep and behavioral problem scores were analyzed by adjusted age, sex, underlying diseases, and medications used and compared between the two groups.
Results:
The study found that 48 % of the TD group and 71 % of the NDDs group were identified as having sleep problems. The NDDs group had significantly higher total TH-JSQ-P score and in five subscales, including obstructive sleep apnea, restless leg syndrome-motor, parasomnias, daytime behaviors, and insomnia/circadian rhythm disorders. Total TH-JSQ-P score was found to have a moderate correlation with internalizing and externalizing behavioral problems.
Conclusion:
Findings suggest that sleep problems are more common in preschool children with NDDs than in TD children and are associated with internalizing and externalizing behavioral problems.
