To evaluate whether sleeping in the supine position resulted in changes in gross or fine motor developmental milestones observed at routinely scheduled well-child checkups at 4 or 6 months of age.
A retrospective chart review.
One private pediatric practice involving 2 full-time and 2 part-time board-eligible or board-certified pediatricians.
The study included 343 full-term infants whose weights were appropriate or large for gestational age, had no history of hospitalization other than for normal newborn care, and were examined in the office for their 4-month well-child checkup within 2 weeks of being 4 months old.
The Denver Developmental Screening Test-Revised was administrated at the 4- and 6-month well-child checkups. The primary sleep positions of the infants were determined by telephone survey, office interview, or letter after the 6-month checkup was completed. Background data collected from the mother for each mother-infant pair included maternal age at the time of birth, parity, and marital status, Medicaid status and ethnicity of the infant, and whether the infant was breast-fed.
Infants who slept in the side or supine position were less likely to roll over at the 4-month checkup than infants who slept primarily in the prone position (P < .001). No significant differences were found when comparison by maternal age, parity, or marital status, Medicaid status or ethnicity of the infant, or the use of breast-feeding were considered. Other motor milestones screened did not show statistically significant changes.
Sleep position significantly influences the age of achieving the gross motor developmental milestone of rolling over; infants who sleep in the side or supine position roll over later than infants who sleep in the prone position.
评估仰卧位睡眠是否会导致在4个月或6个月龄定期进行的健康儿童检查中观察到的大运动或精细运动发育里程碑出现变化。
一项回顾性图表审查。
一家私人儿科诊所，有2名全职和2名兼职的具备委员会资格或获得委员会认证的儿科医生。
该研究纳入了343名足月儿，其体重与胎龄相称或较大，除正常新生儿护理外无住院史，并在4个月大后2周内在诊所接受了4个月龄的健康儿童检查。
在4个月和6个月的健康儿童检查中进行丹佛发育筛查测试修订版。婴儿的主要睡眠姿势在6个月检查完成后通过电话调查、门诊访谈或信件确定。为每对母婴从母亲处收集的背景数据包括出生时的母亲年龄、产次、婚姻状况、婴儿的医疗补助状况和种族，以及婴儿是否母乳喂养。
与主要俯卧位睡眠的婴儿相比，侧卧位或仰卧位睡眠的婴儿在4个月检查时翻身的可能性较小（P <.001）。在考虑按母亲年龄、产次、婚姻状况、婴儿的医疗补助状况或种族，或母乳喂养的使用情况进行比较时，未发现显著差异。筛查的其他运动里程碑未显示出统计学上的显著变化。
睡眠姿势显著影响实现翻身这一大运动发育里程碑的年龄；侧卧位或仰卧位睡眠的婴儿比俯卧位睡眠的婴儿翻身更晚。
