Ninety-four infants with birth weights less than 1,501 g were evaluated on neurologic functioning and mental abilities at 1 year and, again, at 3 to 4 years of age. Results of the examination showed high correspondence in neurologic status and in mental ability between infancy and the preschool period, particularly for children who were diagnosed as clearly normal or abnormal at 1 year. In addition, poorer performance in a test of infant mental ability (which relies primarily on sensorimotor skills), in motor skills, and in neurologic functioning, respectively, were linked to lower IQ, difficulties in expressive language, and articulation deficits at the preschool age. Socioeconomic status predicted 3-year IQ scores and changes in mental ability scores but was not a factor in determining either preschool age neurologic status or changes in neurologic status in the children studied. Socioeconomic status of the children was less predictive of preschool outcome than results of the 1-year examinations.
对94名出生体重低于1501克的婴儿在1岁时以及再次在3至4岁时进行了神经功能和智力评估。检查结果显示，婴儿期和学龄前儿童在神经状态和智力方面具有高度一致性，尤其是对于1岁时被诊断为明显正常或异常的儿童。此外，婴儿智力测试（主要依赖感觉运动技能）、运动技能和神经功能测试中表现较差，分别与学龄前儿童较低的智商、表达语言困难和发音缺陷有关。社会经济地位可预测3岁时的智商分数和智力能力分数的变化，但在所研究的儿童中，它不是决定学龄前神经状态或神经状态变化的因素。与1岁时的检查结果相比，儿童的社会经济地位对学龄前结果的预测性较低。
