Abstract

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.
围产期的某些特征对婴儿早期运动能力的影响
背景。较低的胎龄会对婴儿的神经发育产生负面影响。早期运动能力是预测神经发育结果的可靠方法。本研究旨在确定婴儿胎龄与早期运动能力之间的相关性,以及多胎妊娠、性别、头颅超声造影(USG)结果和出生体重在这种关系中的作用。本研究对 139 名出生后 9-17 周的婴儿进行了录像。录像采用运动优化评分-修订版(MOS-R)进行评估。使用结构方程建模工具对模型进行路径分析。胎龄与 MOS-R 之间存在微弱的正相关。在孕龄与 MOS-R 的关系中,多胎妊娠、性别和 USG 结果具有调节作用。异常 USG、男性性别和单胎妊娠会将这种相关性提高到中等水平,而正常 USG 则会降低这种相关性的强度。女性和双胎妊娠在模型中不显著。出生体重对胎龄和 MOS-R 之间的关系有完全的中介作用。胎龄较小或出生体重较轻的婴儿、男婴和头颅 USG 有问题的婴儿的早期运动能力可能较差。
