To determine whether motor development in premature infants varies according to sleep position, we evaluated 213 infants <1750 g birth weight enrolled in the Collaborative Home Infant Monitoring Evaluation (CHIME). At 56 weeks postconceptional age (PCA), sleep position was determined by maternal report, and the Bayley Scales of Infant Development 2nd Edition (BSID-II) were performed. Infants who slept supine were less likely than infants who slept prone to receive credit for maintaining the head elevated to 45 degrees (p = .021), and infants who slept nonprone were less likely than prone sleepers to receive credit for maintaining the head elevated to 90 degrees and lowering with control (p = .001). The Psychomotor and Mental Development Indices at 56 and 92 weeks PCA were not altered by usual sleep position at 56 weeks PCA. In summary, infants sleeping supine are less able to lift the head and lower with control at 56 weeks PCA, but global developmental status was unaffected. Supine sleeping has been associated with decreased risk for sudden infant death syndrome, but compensatory strategies while awake may be needed to avoid delayed acquisition of head control.
为了确定早产儿的运动发育是否因睡眠姿势而异，我们评估了参与协作家庭婴儿监测评估（CHIME）的213名出生体重<1750克的婴儿。在孕龄（PCA）56周时，通过母亲报告确定睡眠姿势，并进行贝利婴儿发育量表第二版（BSID-II）测试。与俯卧睡眠的婴儿相比，仰卧睡眠的婴儿在将头部抬高到45度时获得分数的可能性较小（p = 0.021），并且与俯卧睡眠的婴儿相比，非俯卧睡眠的婴儿在将头部抬高到90度并能控制地放下时获得分数的可能性较小（p = 0.001）。在PCA 56周和92周时的心理运动和智力发育指数并未因PCA 56周时的通常睡眠姿势而改变。总之，在PCA 56周时，仰卧睡眠的婴儿抬起头部并能控制放下的能力较弱，但整体发育状况未受影响。仰卧睡眠与婴儿猝死综合征风险降低有关，但可能需要在清醒时采取补偿策略以避免头部控制能力的延迟获得。
