背景:较低的胎龄对婴儿的神经发育结局产生负面影响。早期运动谱是预测神经发育结果的可靠方法。这项研究旨在确定胎龄与婴儿早期运动能力之间的相关性,以及多胎妊娠的作用。性别,颅骨超声检查(USG)结果,和出生体重在这种关系中。
方法:这项研究包括139名婴儿,谁是视频记录后9-17周。使用修正的运动最优性评分(MOS-R)评估记录。结构方程建模工具用于模型的路径分析。
结果:胎龄与MOS-R之间存在弱正相关。在胎龄与MOS-R之间的关系中,多胎妊娠,性别,USG结果具有调节作用。当异常USG时,男性,单胎妊娠将这种相关性提高到中等水平,正常USG降低了相关性的强度。在该模型中,女性和双胎妊娠是不显著的。出生体重对胎龄与MOS-R之间的关系具有完全中介作用。
结论:胎龄较小或出生体重较低的婴儿,男婴,并且在颅骨USG上有问题的婴儿的早期运动能力可能较差。
BACKGROUND: Lower gestational age negatively affects the neurodevelopmental outcomes of infants. Early motor repertoire is a reliable way to predict neurodevelopmental outcomes. This study aimed to determine the correlation between gestational age and early motor repertoire in infants and also the roles of multiple pregnancies, gender, cranial utrasonography (USG) results, and birth weight in this relationship.
METHODS: This study included 139 infants, who were video recorded 9-17 weeks post-term. The recordings were evaluated using the Motor Optimality Score-Revised (MOS-R). Structural equation modeling tool was used for the path analysis of the models.
RESULTS: There was a weak positive correlation between gestational age and the MOS-R. In the relationship between gestational age and the MOS-R, multiple pregnancies, gender, and USG outcomes had a moderating effect. While abnormal USG, male gender, and singleton pregnancy increased this correlation to a moderate level, normal USG reduced the strength of the correlation. Female and twin pregnancies were non-significant in the model. Birth weight had a full mediating effect on the relationship between gestational age and the MOS-R.
CONCLUSIONS: Infants with younger gestational age or lower birth weight, male infants, and infants with problems on cranial USG may have poorer early motor repertoire.
