Clocks Sleep. 2025 May 15;7(2):25. doi: 10.3390/clockssleep7020025.
This study explored the impact of lifestyle habits and sensory processing patterns on sleep quality by analyzing body movements (BMs) during the first and last 3 h of sleep in toddlers. We collected cross-sectional data about sleep-related habits from 58 toddlers using a mobile application. Actigraphy measured BMs during nighttime sleep and 1 h before bedtime, as well as sleep latency, over 8 consecutive days. The Infant/Toddler Sensory Profile was used to assess the toddlers' sensory processing patterns. The participants had a mean age of 22.0 ± 2.0 months. BMs were significantly lower during the first 3 h of sleep. Longer sleep latency was significantly associated with media use and higher activity levels before bedtime. Ending a nap earlier and consuming a substantial breakfast were correlated with lower BMs during the first 3 h of sleep. Auditory and oral sensory scores were positively correlated with BMs during the first 3 h of sleep. However, no specific factors related to lifestyle habits or sensory processing patterns were found to correlate with BMs during the last 3 h of sleep. Lifestyle habits and sensory processing patterns have a significant impact on toddlers' sleep quality, emphasizing the importance of appropriate routines and environments.
本研究通过分析幼儿睡眠最初3小时和最后3小时的身体运动（BMs），探讨生活方式习惯和感觉加工模式对睡眠质量的影响。我们使用一款移动应用程序收集了58名幼儿与睡眠相关习惯的横断面数据。活动记录仪在连续8天内测量了夜间睡眠期间、睡前1小时的身体运动以及睡眠潜伏期。使用《婴幼儿感觉概况量表》评估幼儿的感觉加工模式。参与者的平均年龄为22.0±2.0个月。睡眠最初3小时的身体运动显著较低。较长的睡眠潜伏期与睡前使用媒体和较高的活动水平显著相关。较早结束午睡和吃丰盛的早餐与睡眠最初3小时较低的身体运动相关。听觉和口腔感觉评分与睡眠最初3小时的身体运动呈正相关。然而，未发现与生活方式习惯或感觉加工模式相关的特定因素与睡眠最后3小时的身体运动相关。生活方式习惯和感觉加工模式对幼儿的睡眠质量有显著影响，强调了适当日常活动和环境的重要性。
