This study was conducted to evaluate cognitive ability in preschoolers born prematurely and to investigate related factors.
A prospective, longitudinal study was conducted with 64 children at 5-6 years of corrected age (CA) (second follow-up) among 76 children who had been assessed at 2.0~3.5 years of CA (first follow-up) from a sample of 343 preterm infants born from 2008 to 2010. To evaluate each child's cognitive ability, during a home visit, we used the Kaufman Assessment Battery for Children-II (KABC-II) at the second follow-up. To explore factors related to cognitive ability, we measured children's hemoglobin level at the second follow-up and used the data collected in our previous study, including the Bayley Scale of Infant Development-II (BSID-II) at the first follow-up.
The mean total KABC-II quotient was 117.0±14.4. The 5-minute Apgar score (β=.29, =.006), hemoglobin level (β=.22, =.032), and the mental development index quotient of the BSID-II (β=.51, <.001) were statistically significant predictors of the KABC-II quotient in multiple linear regression analysis.
The cognitive function of young children born prematurely was influenced by early neurodevelopment and factors reflecting their health status, such as anemia and a low 5-minute Apgar score.
本研究旨在评估早产学龄前儿童的认知能力并调查相关因素。
对2008年至2010年出生的343名早产婴儿样本中76名在矫正年龄（CA）2.0至3.5岁时（首次随访）接受评估的儿童中的64名在矫正年龄5至6岁时（第二次随访）进行了一项前瞻性纵向研究。为评估每个孩子的认知能力，在第二次随访的家访期间，我们使用了考夫曼儿童评估量表第二版（KABC-II）。为探究与认知能力相关的因素，我们在第二次随访时测量了儿童的血红蛋白水平，并使用了我们之前研究中收集的数据，包括首次随访时的贝利婴儿发展量表第二版（BSID-II）。
KABC-II商数的平均总分是117.0±14.4。在多元线性回归分析中，5分钟阿氏评分（β = 0.29，P = 0.006）、血红蛋白水平（β = 0.22，P = 0.032）以及BSID-II的智力发展指数商数（β = 0.51，P < 0.001）是KABC-II商数的统计学显著预测因素。
早产幼儿的认知功能受早期神经发育以及反映其健康状况的因素影响，如贫血和低5分钟阿氏评分。
