To examine the trajectories of sleep duration and nocturnal awakenings in infants from 6 to 18 months of age and to identify predictors of short sleep duration and nocturnal awakenings.
Data for this study come from the Norwegian Mother and Child Cohort Study conducted at the Norwegian Institute of Public Health. A total of 55,831 mother reports of child sleep were used to estimate the stability and predictors of awakenings and short sleep.
Nocturnal awakenings were frequent among 6-month-old children. Although there was an overall reduction in both sleep duration and nocturnal awakenings from 6 to 18 months, the chronicity of sleep problems was high and impacted by prior sleep behavior and sleeping arrangements. Bedsharing was an independent and graded predictor of nocturnal awakenings and short sleep duration, also after controlling for prior sleep. Breastfeeding was related to concurrent nocturnal awakening but was not negatively related to later nocturnal awakenings.
Considering the chronicity of nocturnal awakening and its association with bedsharing, our findings support current recommendations of reducing bedsharing to improve sleep among infants.
研究6至18个月大婴儿的睡眠时间轨迹和夜间觉醒情况，并确定短睡眠时间和夜间觉醒的预测因素。
本研究的数据来自挪威公共卫生研究所开展的挪威母婴队列研究。总共55831份母亲关于孩子睡眠的报告被用于估计觉醒和短睡眠的稳定性及预测因素。
6个月大的儿童夜间觉醒频繁。尽管从6个月到18个月，睡眠时间和夜间觉醒总体上都有所减少，但睡眠问题的持续性较高，且受到先前睡眠行为和睡眠安排的影响。即使在控制了先前的睡眠情况后，同床睡眠仍是夜间觉醒和短睡眠时间的独立且分级的预测因素。母乳喂养与同时期的夜间觉醒有关，但与后期夜间觉醒无负相关。
考虑到夜间觉醒的持续性及其与同床睡眠的关联，我们的研究结果支持当前关于减少同床睡眠以改善婴儿睡眠的建议。
