This study examined sleep-wake patterns in 3 matched comparison groups of preschool-aged children: children with autism (AUT), children with developmental delay (DD) without AUT, and children who are developing typically (TYP). Sleep was assessed via actigraphy and parent-report diaries for 7 consecutive 24-hr periods across 3 time points: at enrollment (n = 194), 3 months later (n = 179), and 6 months after enrollment (n = 173). At each recording period, children in the AUT group slept less per 24-hr period, on average, and were less likely to awaken at night than children in the other two groups. In contrast, children in the DD group had more frequent and longer duration nighttime awakenings than children in the AUT group. Overall, children in the 2 neurodevelopmentally disordered groups demonstrated more night-to-night variability in their sleep-wake measures than children in the TYP group.
本研究考察了三组匹配的学龄前儿童的睡眠-觉醒模式：自闭症儿童（AUT）、无自闭症但发育迟缓的儿童（DD）和正常发育的儿童（TYP）。通过活动记录仪和家长日记，在三个时间点连续评估 7 天 24 小时的睡眠：入组时（n = 194）、3 个月后（n = 179）和入组后 6 个月（n = 173）。在每个记录期内，AUT 组的儿童平均每 24 小时睡眠时间较少，夜间醒来的可能性也低于其他两组儿童。相比之下，DD 组的儿童夜间觉醒次数更频繁，持续时间更长。总体而言，与 TYP 组相比，这两组神经发育障碍儿童的睡眠-觉醒指标的夜间变化更大。
