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.

我们的研究对象是出生体重极低/极低的婴儿。起初，在 NICU 中，护士使用新生儿行为评定量表（缩写）对他们进行评定（N=24）。于4、10、18个月龄进行京都发育测试，对测试过程中婴儿的行为进行录像，并采用一零抽样法进行分析（N=42）。我们发现，在 NICU 中被评为更活跃的婴儿在 4 个月大时哭闹频率更高 (p=0.07)。在 NICU 中被评定为更易怒、不太安抚、不太可爱或强化价值较差（对护理人员吸引力较小）的婴儿在 4 个月时表现出较高的下肢运动频率（p<0.1、p<0.1），p<0.1，p<0.05，分别）。被评为不太可爱的婴儿在 4 个月大时也表现出较高的上肢运动频率（p<0.05）。婴儿在 4 个月时表现出较高的上肢和下肢运动频率，但在 10 个月时表现出较低的对测试者的视觉固定频率（p<0.05，p<0.1）。 10 个月时较少频繁地注视测试者可能是未来注意力不集中的先兆，而 4 个月时上肢和下肢更频繁的运动也可能是未来注意力不集中的较早先兆。尤其是下肢运动频繁的儿童，在NICU中被评为更易激惹、更不那么安抚、更不可爱、强化价值更差。我们的一些受试者也是我们早期干预项目的受试者。我们应该继续随访受试者的长期后遗症。早期干预对行为问题出现的影响仍有待未来研究。
