目的虽然体动记录仪在儿科睡眠研究中越来越受欢迎，但体动记录仪作为睡眠-觉醒模式估计的有效性仍然存在疑问。特别是，在用于确定睡眠开始潜伏期的评分规则方面，该领域几乎没有一致性。本研究的目的是评估不同的不动标准，以衡量儿童和青少年的入睡潜伏期。 95 名青少年（年龄 3-17 岁，46% 为男性）在儿科睡眠实验室进行夜间多导睡眠监测时佩戴了动态监测公司 Motionlogger 睡眠手表 (AMI) 和飞利浦伟康 Mini-Mitter Actiwatch-2 (PRMM)。我们使用不同的算法（Sadeh 和 Cole-Kripke）和设备的灵敏度设置（低、中、高）检查了不同的睡眠开始潜伏期评分规则（3、5、10、15 和 20 分钟的不动）。还对不同年龄组（学龄前儿童、学龄儿童、青少年）和睡眠呼吸障碍状态（无阻塞性睡眠呼吸暂停 [OSA]、轻度 OSA、有临床意义的 OSA）进行了比较。对于 AMI 设备，较短的评分规则最适合儿童，较长的评分规则最适合青少年，较短的评分规则在睡眠呼吸障碍组中效果最好。对于 PRMM 设备，中等至较长的评分规则在不同年龄和睡眠呼吸障碍组中表现最佳。鼓励研究人员确定最适合其感兴趣人群的评分规则。未来需要对更大的儿童和青少年样本进行研究，以进一步验证活动记录不动作为入睡潜伏期的指标。
Purpose While actigraphy has gained popularity in pediatric sleep research, questions remain about the validity of actigraphy as an estimate of sleep-wake patterns. In particular, there is little consistency in the field in terms of scoring rules used to determine sleep onset latency. The purpose of this study was to evaluate different criteria of immobility as a measure of sleep onset latency in children and adolescents.Ninety-five youth (ages 3-17 years, 46 % male) wore both the Ambulatory Monitoring Inc. Motionlogger Sleep Watch (AMI) and the Philips Respironics Mini-Mitter Actiwatch-2 (PRMM) during overnight polysomnography in a pediatric sleep lab. We examined different sleep onset latency scoring rules (3, 5, 10, 15, and 20 min of immobility) using different algorithms (Sadeh and Cole-Kripke) and sensitivity settings (low, medium, high) for the devices. Comparisons were also made across age groups (preschoolers, school-aged, adolescents) and sleep disordered breathing status (no obstructive sleep apnea [OSA], mild OSA, clinically significant OSA).For the AMI device, shorter scoring rules performed best for children and longer scoring rules were better for adolescents, with shorter scoring rules best across sleep disordered breathing groups. For the PRMM device, medium to longer scoring rules performed best across age and sleep disordered breathing groups.Researchers are encouraged to determine the scoring rule that best fits their population of interest. Future studies are needed with larger samples of children and adolescents to further validate actigraphic immobility as a proxy for sleep onset latency.
