Sleep problems in a population-based cohort of primary school age children with Cerebral Palsy

Aims: To examine sleep problems in a population-based sample of school-aged children (8-12yo) with Cerebral Palsy (CP) Method: Eighty-six children (mean 9 years, 5 months, SD = 1 year, 6 months; male = 60) with CP (Gross Motor Function Classification System; GMFCS I=46; II=21; III=9; IV=6; V=6) participated. Classifications/assessments included: Sleep Disturbance Scale for Children (SDSC), Gross Motor Function Measure (GMFM-66), Manual Ability Classification System (MACS), Communication Function Classification System (CFCS), Strengths and Difficulties Questionnaire (SDQ) and the Cerebral Palsy- Quality of Life (CP-QOL) Pain Impact subscale. Analysis included linear and logistic regression. Results: 38 (44 %) children were within the clinical range for sleep problems. Sleep problems were significantly associated with epilepsy, (95 % CI) = 14.48 (7.95 to 21.01), gross motor function, -0.13 (-0.26 to -0.01), manual ability, 7.26 (0.82 to 13.69), communication, 10.01 (2.21 to 17.80), child behaviour, 1.134 (0.74 to 1.53), and pain related QOL, 0.33 (0.12 to 0.53). For the multivariable model, sleep problems remained significantly associated with epilepsy, b (95 % CI) = 11.72 (4.88 to 18.57), child behaviour, 1.03 (0.65 to 1.41) and pain-related QOL, 0.21 (0.29 to 0.38). Conclusions: Sleep problems are common and associated with epilepsy, child behaviour and pain related QOL.
