From September 2017 to February 2018, 650 disabled children and adolescents aged 6-to 17-year-old in Beijing were matched 1∶1 to those in normal physical condition with same age, gender and place of residence. All children and adolescents were investigated for self-injury status in the last year to understand the difference of self-injury incidence between groups. Multivariate unconditional logistic regression model was applied for exploring relevant factors of self-injury of children and adolescents. This study found that the disability, insufficient sleep, difficulty falling asleep, and sleeping late were associated with self-injury of children and adolescents.

【Objective】 To examine the association between psychological behavioral problems and sleep problems in disabled children in Beijing, in order to provide reference for reducing the sleep problems of disabled children. 【Methods】 From September 2017 to February 2018, children with disabilities aged 6 to 17 years were selected by random sampling, and were investigated by a self-designed questionnaire to get their demographic characteristics.Pediatric Symptom Checklist-17 (PSC-17) was used to assess psychological and behavioral problems.The relationship between psychological behavior and sleep problems was analyzed by binary Logistic regression. 【Result】 Totally 650 children with disabilities were included in the study.The detection rates of sleep problems was significantly different in children with different genders, different school styles, different types of disabilities and different grades of disabilities (χ²=3.984, 4.437, 12.925, 18.104, P<0.001). There was statistically significant difference in the detection rate of sleep problems between children with and without psychological and behavioral problems (χ²=30.722, P<0.001).Psychological and behavioral problems were the main risk factors for sleep problems of disabled children (OR=2.540, 95%CI:1.740 - 3.709).The risk of sleep problems in day students with disabilities was 1.577 times as high as that of boarders with disabilities. 【Conclusions】 Psychological and behavioral problems of disabled children are related to sleep problems.Improving psychological and behavioral status can effectively prevent their sleep problems.
