充足的体力活动与成年人睡眠的改善有关。然而，这些关联在儿科人群的研究中差异很大，文献中没有涉及婴儿的研究。因此，这项前瞻性观察性研究旨在研究婴儿身体活动和睡眠模式之间的关系。共有183名6个月大的健康婴儿佩戴活动仪7天，以测量身体活动和睡眠。父母和照顾者在同一时期完成了睡眠活动日记，记录了不同类型的婴儿活动。每天平均花费在屏幕时间或有限的身体活动上的时间，包括基于屏幕的时间（例如，观看电视或其它电子设备）和基于非屏幕的活动（例如，安静玩耍或由看护者抱着或坐在高脚椅、秋千或摇椅上时婴儿运动受限）的平均时间为6.68小时（SD = 1.99），占白天清醒时间的47.50%（SD = 13.73）。我们发现，65名（35.5%）婴儿在研究期间参与了一些屏幕时间，其中10名（5.5%）婴儿的平均每日屏幕时间>30分钟。在我们的多元线性回归模型中，每天屏幕时间或有限的体力活动时间与每天24小时睡眠时间的减少显著相关（p < 0.01）。我们的研究结果表明，减少屏幕时间或有限的身体活动可能是促进充足睡眠和延长婴儿每日睡眠时间的一种方法。
Adequate physical activity is associated with improved sleep in adults. Such associations, however, vary greatly across studies in pediatric populations, with no studies involving infants found in the literature. This prospective observational study was designed, therefore, to examine the association between physical activity and sleep patterns in infants. A total of 183 healthy infants aged 6 months wore an actigraph for 7 days to measure physical activity and sleep. Parents and caregivers completed a sleep-activity diary over the same period documenting the different types of infant activities. Daily mean time spent in screen-time-or-limited physical activity, including screen-based (e.g., watching television or other electronic devices) and non-screen based activity (e.g., quiet play or restricted infant movement when carried by caregivers or seated in high chairs, swings, or bouncer seats), was 6.68 hr (SD = 1.99), which represented 47.50% of daytime waking hours (SD = 13.73). We found that 65 (35.5%) infants engaged in some screen time during the study, with 10 (5.5%) infants having an average daily screen time >30 min. In our multivariate linear regression model, more hours of screen-time-or-limited physical activity per day were significantly associated with a decrease in total daily 24 hr sleep duration (p < 0.01). Findings from our study suggest that reducing screen-time-or-limited physical activity might be an approach for promoting adequate sleep and lengthening infant daily sleep duration.
