This study examined whether 3-15, month-old cosleeping infants displayed differences in time spent in active versus quiet sleep, and in the number/duration of nighttime awakenings when compared with solitary-sleeping infants; and also whether they spent the majority of the night sleeping face-to-face, as previously reported. Nine cosleeping and nine solitary-sleeping infants were matched on age, gender, ethnicity, maternal age, and family SES. Video recordings of nighttime sleep yielded percentage of time in active sleep, quiet sleep, and awake, number of wakenings, and the percentage of time cosleeping infants and mothers spent face-to-face. Across age, cosleeping infants had more awakenings per night mean 5.8(1.50) versus 3.2(1.95); t = 3.16, p = .006). The percent of the nighttime spent awake did not differ between groups, suggesting that cosleeping infants had shorter awakenings. Cosleeping infants spent 40% of the night face-to-face with their mothers.
本研究调查了3至15个月大的同床睡眠婴儿与独自睡眠婴儿相比，在主动睡眠与安静睡眠的时长、夜间觉醒次数/时长方面是否存在差异；以及他们是否如先前报道的那样，夜间大部分时间是面对面睡眠。9名同床睡眠婴儿和9名独自睡眠婴儿在年龄、性别、种族、母亲年龄和家庭社会经济地位方面进行了匹配。夜间睡眠的视频记录得出了主动睡眠、安静睡眠和清醒状态下的时间百分比、觉醒次数，以及同床睡眠婴儿与母亲面对面睡眠的时间百分比。在各年龄段中，同床睡眠婴儿每晚的觉醒次数更多（平均5.8次[1.50]对3.2次[1.95]；t = 3.16，p = .006）。两组之间夜间清醒时间的百分比没有差异，这表明同床睡眠婴儿的觉醒时间较短。同床睡眠婴儿夜间有40%的时间与母亲面对面。
