1、小于胎龄儿体格发育3年随访结果研究【摘要】目的探讨小于胎龄儿的生长发育规律，为儿童早期体格发育研究提供依据。方法对选取的212名小于胎龄儿和对照儿童定期测量身长和体重，并计算生长速率；以个体身长别体重超过标准体重的方法筛选超重、肥胖；用标准差分（Z分）筛选4种中重度营养不良。结果小于胎龄儿体重增长速率2岁内高于足月正常儿，身长增长速率1岁内高于足月胎龄儿；3岁内身长、体重、身长别体重Z分均值均明显低于足月胎龄儿；小于胎龄儿1，3岁时中重度营养不良率均显著高于足月正常儿（P值均＜0.05）。结论小于胎龄儿体重2岁内呈现追赶生长，身长1岁内呈现追赶生长；3岁时生长水平仍落

7、dies小于胎龄儿（smallforgestationalageinfants,SGA）是指出生体重低于同胎龄正常平均体重的第10百分位者，其病理基础是宫内营养不良或宫内生长受限（intrauterinegrowthrestriction,IGR），占低出生体重儿的1/3～2/3，是儿童保健门诊重点管理对象。近年来的研究显示，SGA生长模式不同于一般儿童，为高年龄段儿童期以及成年期健康问题埋下“祸根”。追踪随访SGA儿童生命早期的生长速率及生长发育规律，是评价相关健康问题的基础。为此，笔者对212名小于胎龄儿进行了3a的随访观察。1对象与方法1.1对
