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.
充足的体育活动与成年人睡眠质量的改善有关。然而，在儿科人群的研究中，这种关联差异很大，文献中未发现涉及婴儿的研究。因此，本前瞻性观察性研究旨在探讨婴儿体育活动与睡眠模式之间的关联。共有183名6个月大的健康婴儿佩戴活动记录仪7天，以测量体育活动和睡眠情况。在此期间，家长和照顾者完成了一份睡眠-活动日记，记录婴儿的不同活动类型。每天花在屏幕时间或有限体育活动上的平均时间，包括基于屏幕的活动（如看电视或其他电子设备）和非屏幕活动（如安静玩耍或照顾者抱着或坐在高脚椅、秋千或婴儿座椅上时婴儿的受限活动）为6.68小时（标准差=1.99），占白天清醒时间的47.50%（标准差=13.73）。我们发现，65名（35.5%）婴儿在研究期间有一些屏幕时间，其中10名（5.5%）婴儿平均每天屏幕时间超过30分钟。在我们的多元线性回归模型中，每天更多的屏幕时间或有限体育活动小时数与24小时总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体育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。
