To formulate an equation estimating months to independent walking in moderate to late preterm infants based on neonatal characteristics and gross motor development from 7 months to independent walking.
Sixty infants born between 32 to 36 weeks were assessed using Alberta Infant Motor Scale (AIMS) for gross motor development. Neonatal characteristics were recorded at 7 months, and caregiver-reported independent walking onset. Pearson correlation analyzed age, AIMS scores, and neonatal factors. Multiple regression developed the prediction equation.
The equation for independent walking onset, which included gestational age (GA) at birth, total AIMS score at 10 months of age (10th AIMS), and birth head circumference (BHC), exhibited a strong correlation (r=0.707) and had a predictive power of 50.0%. The equation is as follows: age onset of independent walking (months)=33.157, -0.296 (GA), -0.132 (10th AIMS), -0.196 (BHC), with an estimation error of 0.631 months.
Neonatal characteristics, such as GA, 10th AIMS, and BHC, are key determinants in estimating the onset of independent walking in moderate to late preterm infants.
根据新生儿特征以及7个月至独立行走阶段的大运动发育情况，制定一个估算中度至晚期早产儿独立行走月龄的公式。
对60名孕周在32至36周之间出生的婴儿，使用艾伯塔婴儿运动量表（AIMS）评估其大运动发育情况。记录婴儿7个月时的新生儿特征以及照料者报告的独立行走开始时间。采用Pearson相关性分析年龄、AIMS评分和新生儿因素。通过多元回归建立预测方程。
独立行走开始时间的方程，包括出生时的孕周（GA）、10个月大时的AIMS总分（第10次AIMS）和出生头围（BHC），显示出很强的相关性（r = 0.707），预测能力为50.0%。该方程如下：独立行走开始月龄 = 33.157 - 0.296（GA） - 0.132（第10次AIMS） - 0.196（BHC），估计误差为0.631个月。
新生儿特征，如孕周、第10次AIMS和出生头围，是估算中度至晚期早产儿独立行走开始时间的关键决定因素。
