Sleep problems of children with Down syndrome in northern China

Abstract

Background: Limited research has looked at the present-day sleep problems among Chinese children with Down syndrome (DS). This study aimed to investigate the situation of the sleep problems of school-aged children with DS in northern China.

Methods: Parents of children with DS were a convenience sample recruited through the special education schools of Shandong Province in China. The Chinese version of the Children's Sleep Habits Questionnaire was applied to assess the sleep problems of children with DS.

Results: Parents of 334 children with DS reported the average sleep duration was 9.7 (9.3-10.2) hours per night, and 62.0% of children with DS were reported sleeping less than 10 h per night. Additionally, the total prevalence rate of sleep problems among children with DS was 69.8%. Sleep-disordered breathing (59.2%), sleep duration (33.8%) and bedtime resistance (32.0%) were the three most commonly reported sleeping problems. Younger children with DS (age 6-8 years) had severe problems with bedtime resistance, sleep anxiety and parasomnias than older children with DS (age 9-12 years) (all P < 0.05).

Conclusion: Sleep problems are prominent among children with DS in northern China and are worthy of attention. Caregivers and health professionals should raise awareness of sleep problems in this group of children and implement targeted interventions to improve their sleep quality as early as possible.
