项目摘要

Our subjects were very- / extremely-low-birthweight infants. At first, In NICU, they were rated by nurses using the Neonatal Behavioral Rating Scale - abbreviated (N=24). At the ages of 4, 10, 18 months, the Kyoto Developmental Test was administrated and infants' behaviors were videotaped during testing and analyzed by one-zero sampling method (N=42). We found that the infants, who were rated as more active in NICU, showed the higher frequency of crying at 4 months of age (p=0.07). The infants, who were rated as more irritable, less soothable, less cuddly, or having poorer reinforcement value (less attractive for a caregiver) in NICU, showed higher frequency of lower-limbs movements at 4 months (p<0.1, p<0.1, p<0.1, p<0.05, respectively). The infants, who were rated as less cuddly, also showed higher frequency of upper-limbs movements at 4 months (p<0.05). The infants, who showed higher frequency of upper- and lower- limbs movements at 4 months, showed lower frequency of visual fixation toward a tester at 10 months (p<0.05, p<0.1). The less frequent visual fixation toward a tester at 10 months might be a precursor of future inattention, and the more frequent movements of upper- and lower- limbs at 4 months also might be an earlier precursor of future inattention. Especially, the children, who showed frequent lower-limb movements, were rated as more irritable, less soothable, less cuddly, and having poorer reinforcement value in NICU.Some of our subjects were also the subjects for our early intervention project. We should continue to follow up long-term sequelae of our subjects. Effects of early intervention on appearance of behavioral problems remain to be investigated in future.

我们的受试者是非常低的次量级婴儿。首先，在NICU，使用新生儿行为评级量表 - 缩写（n = 24），由护士进行评分。在4、10、18个月的年龄中，对京都发育测试进行了管理，并在测试过程中对婴儿的行为进行了录像，并通过一零采样方法进行了分析（n = 42）。我们发现，在NICU中被评为更活跃的婴儿在4个月大时表现出较高的哭泣频率（P = 0.07）。婴儿被评为更加烦躁，更舒缓，可爱的人，或者在NICU中具有较差的增强值（对护理人员的吸引力较低），在4个月时显示了下limbs运动的频率较高（p <0.1，p <0.1，p <0.1，p <0.1，p <0.1，p <0.05，分别为p <0.1，p <0.05）。婴儿被评为不那么可爱的婴儿在4个月时也显示出较高的上限运动频率（p <0.05）。婴儿在4个月时显示出较高的上和下肢运动频率，在10个月时显示出较低的视觉固定频率（p <0.05，p <0.1）。在10个月时，对测试仪的视觉固定频率较低，这可能是未来不集中注意力的前身，而在4个月时，上肢和下肢的更频繁运动也可能是未来不集中注意力的早期前体。尤其是，表现出频繁的下限运动的儿童被评为更加烦躁，更舒缓，不那么可爱，并且在NICU中具有较差的增强价值。我们受试者的某些人也是我们早期干预项目的主题。我们应该继续跟进对象的长期后遗症。早期干预对行为问题出现的影响仍有待研究。
