To determine, in preschool- and school-aged children with cerebral palsy (CP): (i) the prevalence of sleep disorders, including disorders of initiation and maintenance of sleep, and (ii) the association between child characteristics and sleep disorders. Children with CP aged 3–12 years were recruited from neurology clinics and a provincial CP registry. Caregivers completed the Sleep Disturbance Scale for Children (SDSC) and a questionnaire on sleep-related characteristics. Children's medical information was collected from the registry and hospital records. 150 children with CP (mean age ± standard deviation: 6.9 ± 2.9 years) completed the study (66 preschool-and 84 school-aged children). An abnormal total score on the SDSC was found in 20.7% of children (10.6% and 28.6% of preschool-and school-aged children, respectively). Overall, 44.0% of children had one or more sleep disorder (24.2% and 59.5% in preschool-and school-aged children, respectively), as determined by subscales of the SDSC. The most common sleep problem, disorders of initiation and maintenance of sleep, was found in 26.0% of children (18.2% of preschool- and 32.1% of school-aged children, respectively). Pain was the strongest predictor of having an abnormal total score and disorders of initiation and maintenance of sleep, with odds ratios (95% confidence intervals) of 6.5 (2.2–18.9) and 3.4 (1.3–9.3), respectively, adjusted for age group and degree of motor impairment. Sleep disorders are prevalent in children with CP, with higher frequencies in school-aged as compared to preschool-aged children. Health care professionals caring for this population should routinely inquire about sleep problems and pain. •In children with cerebral palsy, nearly half of caregivers reported ≥ one sleep disorder.•Sleep problems are prevalent in school-aged children with cerebral palsy.•Disorders of initiation and maintenance of sleep was the most common sleep problem.•Pain was strongly associated with sleep problems in children with cerebral palsy.
