[Research progress on neurodevelopmental outcomes of small for gestational age infants].

The incidence of perinatal disease and perinatal mortality in small for gestational age infants increased significantly. This group of people is prone to a variety of long-term metabolic diseases and cardiovascular diseases, and is also prone to growth retardation and neurodevelopmental delay, which will seriously affect the long-term quality of life of children. The article studies the neurodevelopmental outcomes of small-for-gestational-age infants. By reviewing and sorting out previous literature, the neurodevelopmental disorders of small-for-gestational-age infants are analyzed according to five aspects: intellectual development, motor development, language development, sensory development, and mental illness. The classification and summary were carried out, and the influencing factors of neurodevelopmental disorders of SGA were also evaluated, so as to provide reference for promoting the improvement of neurodevelopmental outcomes of small-for-gestational-age infants.小于胎龄儿（small for gestational age，SGA）不仅是各种围产期疾病发生和围产期死亡的高危人群，也易合并多种远期代谢性疾病、心血管疾病，同时该类人群生长发育迟缓、神经发育障碍的风险也明显增加，严重影响儿童远期生存质量。本文关注SGA远期神经发育结局，从智力发育、运动发育、语言发育、感知觉发育、精神疾病等进行分类总结归纳，同时评估其神经发育障碍发生的危险因素，为促进SGA神经发育结局的改善提供参考。.
