To investigate sleep and its predictors in preschoolers with mild traumatic brain injury (mTBI).
The sample included 225 children, aged 18 to 60 months, divided into 3 groups: children with accidental mTBI (n = 85), children with orthopedic injury (n = 58), and typically developing children (n = 82). Retrospective reports of preinjury sleep and family functioning were obtained as part of a baseline assessment at the time of recruitment. Parental ratings of sleep problems were collected 6 months postinjury on the full sample, and actigraphy data were collected on a subset of children. Demographic, preinjury, and periinjury factors were examined as potential predictors of sleep outcomes.
No group differences were found in ratings of sleep problems or for nighttime sleep duration and sleep efficiency, as measured by actigraphy. Besides, preexisting sleep disturbances and brain injury resulting in alteration of consciousness were identified as predictors of poorer sleep in the mTBI group.
Although mTBI did not result in group-level sleep disturbances 6 months postinjury, the findings suggest that premorbid and injury-related factors place some children at risk for poorer sleep after mTBI. These factors should be documented so clinicians can intervene early.
研究轻度创伤性脑损伤（mTBI）学龄前儿童的睡眠情况及其预测因素。
样本包括225名年龄在18至60个月的儿童，分为3组：意外mTBI儿童（n = 85）、骨科损伤儿童（n = 58）和发育正常儿童（n = 82）。作为招募时基线评估的一部分，获取了伤前睡眠和家庭功能的回顾性报告。在伤后6个月收集了全样本儿童睡眠问题的家长评分，并收集了部分儿童的活动记录仪数据。对人口统计学、伤前和伤时因素进行了检查，作为睡眠结果的潜在预测因素。
通过活动记录仪测量，在睡眠问题评分、夜间睡眠时间和睡眠效率方面未发现组间差异。此外，伤前存在的睡眠障碍和导致意识改变的脑损伤被确定为mTBI组睡眠较差的预测因素。
虽然mTBI在伤后6个月未导致组水平的睡眠障碍，但研究结果表明，病前和损伤相关因素使一些儿童在mTBI后有睡眠较差的风险。应记录这些因素，以便临床医生能够早期干预。
