小于胎龄儿（small for gestational age，SGA）是一组异质性疾病，基因检测技术的进步为其精准诊断提供可能。随着对SGA的认识加深，宫内不良生长与生后不同的生长模式对SGA近期及远期的健康结局造成诸多不良影响。本文概述SGA不同时期的管理重点与策略，以期为实现终生管理提供思路。
Abstract:
Small for gestational age（SGA） is a group of heterogeneous diseases，and technical advances in gene detection provide the opportunity for its precision diagnosis. With deepening understanding of SGA，clinicians recognize a poor fetal growth as well as post－natal adverse growth modes have adverse effects on the short-term and long-term health outcomes. Therefore，we outline the manage－ment priorities and strategies in different periods of SGA to provide basics for the realization of lifelong management.
