本研究评估了出生前的运动活动是否可以预测新生儿、婴儿和学步儿童的运动行为和气质。在52例健康胎儿妊娠24、30和36周时，采用多普勒超声技术采集胎儿运动活动的三个测量指标（活动水平、幅度和运动次数）。产后数据收集包括产后2周的神经行为评估（n = 41），以及1岁和2岁时的实验室行为观察（n = 35）。妊娠期个体运动活动稳定。胎儿运动和新生儿行为之间的预测关系不一致：在36周的运动行为与新生儿易怒和运动发育之间发现了显著但很小的正相关。36周胎儿活动水平与男孩观察到的1年活动水平呈正相关（但女孩呈负相关），母亲报告的2年活动水平。胎儿运动对1岁时的窘迫和2岁时的行为抑制具有一致的负面预测作用，占这些测量差异的21%至43%。运动行为的胎儿内变异性使其成为预测新生儿成熟结果的相对不稳定的指标，这是相对受限的，但胎儿运动激活素似乎可以预测与幼儿期调节行为相关的气质属性。(C) 2002 Wiley期刊有限公司
This study evaluated whether motor activity prior to birth is predictive of motor behavior and temperament in neonates, infants, and toddlers. Three measures of fetal motor activity (activity level, amplitude, and number of movements) were collected at 24, 30, and 36 it weeks of gestation in 52 healthy fetuses using Doppler-based actography. Postnatal data collection included a neurobehavioral assessment at 2-weeks postpartum (n = 41), and laboratory-based behavioral observations at 1 and 2 years of age (ns = 35). Individual stability in motor activity was present during gestation. Predictive relations between fetal movement and neonatal behavior were inconsistent: significant but small positive associations were detected between motor behavior at 36 weeks and neonatal irritability and motor development. Fetal activity level at 36 weeks was positively associated with observed 1-year activity level for boys (but inversely N- related for girls) and maternal report of activity level at 2 years. Fetal movement was consistently and negatively predictive of distress to limitations at 1 year and behavioral inhibition at 2 Years, accounting for 21 to 43% of the variance in these measures, Intrafetal variability in motor behavior make this a relatively unstable metric for prediction to neonatal maturational outcomes, which are relatively constrained, but fetal motor activin, appears to predict temperament attributes related to regulatory behaviors in early childhood.
