This prospective repeated-measures study explored potential factors (postmenstrual age, body weight, gender, chronological age, illness severity, and circadian rhythm) related to preterm infants' circadian sleep/wake patterns. Circadian sleep/wake patterns were measured using an Actiwatch for 3 continuous days in preterm infants (gestational age of 28-36.4 weeks) in a neonatal intensive care unit and hospital nursery. Potential factors associated with circadian sleep/wake patterns were analyzed using the generalized estimating equation. For our sample of 30 preterm infants, better sleep/wake patterns were associated with male gender, younger postmenstrual and chronological age, lower body weight, and less illness severity. Preterm infants' total sleep time ( B = 41.828, p < .01) and percentage of sleep time ( B = 3.711, p < .01) were significantly longer at night than during the day. These findings can help clinicians recognize preterm infants' sleep problems, signaling the need to provide individualized support to maintain these infants' sleep quality during their early life.
这项前瞻性重复测量研究探讨了与早产儿昼夜睡眠/觉醒模式相关的潜在因素（月经后年龄、体重、性别、实足年龄、疾病严重程度和昼夜节律）。在新生儿重症监护病房和医院托儿所，使用活动记录仪对孕周为28 - 36.4周的早产儿连续3天测量昼夜睡眠/觉醒模式。使用广义估计方程分析与昼夜睡眠/觉醒模式相关的潜在因素。对于我们的30名早产儿样本，更好的睡眠/觉醒模式与男性性别、较小的月经后和实足年龄、较低的体重以及较轻的疾病严重程度相关。早产儿的总睡眠时间（B = 41.828，p <.01）和睡眠时间百分比（B = 3.711，p <.01）在夜间显著长于白天。这些发现可以帮助临床医生识别早产儿的睡眠问题，表明需要提供个性化支持以在其生命早期维持这些婴儿的睡眠质量。
