胎儿状态组织反映了中枢神经系统的发育，但也可能预示着出生后状态组织的个体差异。本研究的目的是确定胎儿状态调节的程度，定义为胎儿心率和运动一致性显示的观察期的百分比，与新生儿状态调节相关。产后2周通过标准神经行为评估评估新生儿状态调节。在52例妊娠24、30和36周正常发育的胎儿中使用心电仪测量生物行为一致性；对其中41名婴儿进行了新生儿评估。生物行为一致性的胎儿内稳定性在36周前未出现。36周一致性较高的胎儿在检查过程中表现出更好的状态调节，包括更多的警觉性和定向性（r（35)=0.29），更少的保持注意力的成本（r = 0.36），更少的烦躁（r = - 0.41），更好的调节能力（r = 0.47），更多的可用状态范围（r = 0.34），并且更有可能在考试中最令人厌恶的部分保持控制F(1,31) = 4.63, p < 0.05）。这些结果支持胎儿状态作为一个稳定的个体属性，在产前和新生儿时期是保守的。(C) 2002爱思唯尔科学爱尔兰有限公司版权所有。
Fetal state organization reflects the development of the central nervous system but may also portend individual differences in postnatal state organization. The goal of the present study was to determine the extent to which fetal state regulation, defined as the percentage of an observation period in which fetal heart rate and movement concordance was displayed, is associated with neonatal state regulation. Neonatal state regulation was evaluated through a standard neurobehavioral assessment at 2 weeks postpartum. Biobehavioral concordance was measured in 52 normally developing fetuses at 24, 30 and 36 weeks gestation using an actocardiograph; the neonatal assessment was administered to 41 of these as infants. Intrafetal stability in biobehavioral concordance did not emerge prior to 36 weeks. Fetuses with higher concordance at 36 weeks were infants that displayed better state regulation during the exam, including more alertness and orientation (r(35)=0.29), less cost of maintaining attention (r = 0.36), less irritability (r = - 0.41), better regulatory capacity (r = 0.47), a greater range of available states (r = 0.34), and were significantly more likely to maintain control during the most aversive portions of the exam F(1,31) = 4.63, p < 0.05). These results support fetal state as a stable individual attribute that is conserved across the prenatal and neonatal periods. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
