Insights
Children with cerebral palsy (CP) experience more sleep disturbances than their siblings. Caregiver sleep issues, like short duration or long latency, are linked to increased sleep problems in children with CP.
Area of Science:
- Pediatric Neurology
- Sleep Medicine
- Developmental Pediatrics
Background:
- Sleep disturbances are prevalent in children with cerebral palsy (CP).
- Understanding the specific types and frequency of sleep issues in CP is crucial for targeted interventions.
- Comparing sleep patterns in children with CP to their healthy siblings can highlight CP-specific challenges.
Purpose of the Study:
- To compare sleep disturbances in Malaysian children with CP (aged 4-18) to their healthy siblings.
- To identify factors associated with sleep disturbances in children with CP.
Main Methods:
- A case-control study involving 109 children with CP and 109 healthy siblings.
- Sleep disturbances were assessed using the Sleep Disturbances Scale for Children (SDSC) questionnaire completed by caregivers.
- Multiple regression analysis was used to identify factors associated with sleep scores in children with CP.
Main Results:
- Children with CP had significantly higher scores on the Total SDSC and several subscales (sleep initiation/maintenance, breathing, transition, hyperhidrosis) compared to siblings.
- Spastic CP was the most common type (89%), with a majority of CP patients at higher Gross Motor Function Classification System (GMFCS) levels (IV-V).
- Caregiver sleep duration (<7 hours) and sleep latency (>30 minutes) were significantly associated with higher Total SDSC scores in children with CP.
Conclusions:
- Sleep disturbances are more frequent in children with CP than in their healthy siblings.
- Caregiver sleep quality and duration are important factors to consider when assessing sleep problems in children with CP.
- Addressing caregiver sleep may be beneficial in managing sleep disturbances in this population.
Aim:
The aim of the study was to compare the frequency and type of sleep disturbances in a group of Malaysian children aged 4 to 18 years with cerebral palsy (CP) with their nearest-age, able-bodied siblings and to identify factors associated with sleep disturbances.
Method:
The study was a case-control study of 109 children with CP (61 males, 48 females; mean age 9 y, SD 3 y 11 mo, range 4-18 y) and their healthy siblings (56 males, 53 females; mean age 10 y, SD 3 y 9 mo, range 4-18 y). The Sleep Disturbances Scale for Children (SDSC) questionnaire was completed by the main caregiver. In children with CP, multiple regression analysis was be used to determine factors related to higher Total SDSC sleep scores.
Results:
Ninety-seven children (89%) had spastic CP, 10 (9%) had dyskinetic CP, and two (2%) had mixed CP. Based on the Gross Motor Function Classification System (GMFSC), 34 patients (31%) were at GMFSC level I or II, 10 patients (9%) at level III, and 65 patients (60%) at level IV or V. Children with CP scored significantly higher than their siblings on Total SDSC and four SDSC subscale scores - difficulty in initiating and maintaining sleep, sleep breathing disorders, sleep-wake transition disorders, and sleep hyperhidrosis. Caregiver sleep duration of less than 7 hours (p=0.02) and caregiver sleep latency of more than 30 minutes (p=0.03) were significantly associated with higher Total SDSC scores. Co-sleeping was not a significant factor.
Interpretation:
Sleep disturbances are more common in children with CP than in their siblings. Attention should be given to caregiver sleep when evaluating sleep disturbances in children with CP as this factor was shown to be associated with higher Total SDSC scores.
