研究目标：本研究将学龄前儿童的体动记录仪与视频睡眠图进行比较，特别强调检测夜间觉醒的准确性。设计：58 名参与者佩戴体动记录仪 1 周，并在佩戴体动记录仪时拍摄 2 个晚上的视频。背景：参与者是单独睡眠者，在家里进行研究。参与者：一组 (n = 22) 被诊断患有自闭症， 另一组（n = 11）有发育迟缓，但没有自闭症，第三组（n = 25）是典型发育中的儿童；年龄范围为 28 至 73 个月（平均年龄 47 个月）； 29名男生，29名女生。干预措施：不适用。测量和结果：通过同时记录的视频睡眠图和体动记录仪对夜间睡眠和觉醒进行评分。通过与视频睡眠图的逐个时期比较来检查体动记录仪的准确性。结果总体一致性为 94%，敏感性为 97%，特异性为 24%。对总体一致性和特异性的统计校正得出 89% 的加权一致性和 27% 的调整特异性。结论：与视频观察相比，体动记录仪在学龄前儿童检测夜间觉醒方面的一致性较差。
Study Objectives: This study compared actigraphy with videosomnography in preschool-aged children, with special emphasis on the accuracy of detection of nighttime awakenings.Design: Fifty-eight participants wore an actigraph for 1 week and were videotaped for 2 nights while wearing the actigraph.Setting: Participants were solitary sleepers, studied in their homes.Participants: One group (n = 22) was diagnosed with autism, another group (n = 11) had developmental delays without autism, and a third group (n = 25) were typically developing children; age ranged from 28 to 73 months (mean age 47 months); 29 boys and 29 girls. Interventions: N/A.Measurements and Results: Nocturnal sleep and wakefulness were scored from simultaneously recorded videosomnography and actigraphy. The accuracy of actigraphy was examined in an epoch-by-epoch comparison with videosomnography. Findings were 94% overall agreement, 97% sensitivity, and 24% specificity. Statistical corrections for overall agreement and specificity resulted in an 89% weighted-agreement and 27% adjusted specificity.Conclusions: Actigraphy has poor agreement for detecting nocturnal awakenings, compared with video observations, in preschool-aged children.
