This study examined sleep, sleepiness, and daytime performance in 68 children with autism, 57 children with intellectual disability (ID), and 69 typically developing preschool children. Children in the autism and ID groups had poorer daytime performance and behaviors than the typically developing children. Children in the ID group also were significantly sleepier than children in both the autism and typically developing groups. These significant differences persisted over 6 months. Actigraph-defined sleep behaviors and problems did not relate to daytime sleepiness or daytime performance and behaviors for the children with autism or the typically developing group. For the ID group, longer night awakenings and lower sleep efficiency predicted more daytime sleepiness. For each group, parent-report sleep problems were associated with more daytime sleepiness and more behavior problems.
本研究调查了 68 名自闭症儿童、57 名智力障碍（ID）儿童和 69 名正常发育的学龄前儿童的睡眠、嗜睡和日间表现。自闭症和 ID 组的儿童日间表现和行为比正常发育儿童差。ID 组的儿童也比自闭症和正常发育组的儿童明显更嗜睡。这些显著差异持续了 6 个月。活动记录仪定义的睡眠行为和问题与自闭症或正常发育组儿童的日间嗜睡或日间表现和行为无关。对于 ID 组，夜间觉醒时间较长和睡眠效率较低预示着更多的日间嗜睡。对于每个组，父母报告的睡眠问题与更多的日间嗜睡和更多的行为问题有关。
