摘要
目的探讨早产适于胎龄儿(AGA)和小于胎龄儿(SGA)的体格生长特征,为今后对早产儿进行有效干预提供依据。方法选择胎龄在28~36+6周的211例早产AGA儿和25例早产SGA儿作为研究对象,出生后定期接受高危儿管理干预,对其0~12个月内的体重、身长及头围分别按足月儿生长标准进行Z评分评估并分析。结果早产AGA儿和早产SGA儿1岁内体重、身长和头围均出现追赶性生长,且增长最快的阶段均在出生后0~6个月,早产AGA和SGA儿体重、身长、SGA儿头围均ΔZ值>0,自出生后3月龄后,AGA儿头围的ΔZ值≥0。早产AGA和SGA儿体重、身长和头围以出生后6个月内ΔZ值最大,6个月后ΔZ值呈现减小趋势;体重追赶速度优于身长追赶速度,体重的Z值中位数均大于身长;早产SGA儿追赶生长速度慢于早产AGA儿,早产AGA儿体重、身长及头围的Z值中位数分别于出生后3、6、9个月龄起>0,早产SGA儿体重、身长和头围的Z值中位数分别于出生后9、12、12个月龄起>0。结论出生后前6个月是早产儿的快速生长期,体重与身长的变化存在不平衡性;早产AGA儿生长潜力大于早产SGA儿。Z评分法是早产儿生长状态评估的一个较好方法,为早产儿营养供给提供参考。
Objective To study the physical growth of preterm appropriate for gestational age(AGA) infants and small for gestational age(SGA) infants in order to provide the basis for the effective intervention of preterm infants.Methods 211 preterm AGA infants and 25 preterm SGA infants with gestational ages between 28~36+6 weeks were enrolled,received regular management and early intervention to high risk infants.The weight,length and head circumference were evaluated by Z score according to the criterions of ages.ResultsIn the first year of life,preterm infants had the catch-up growth in weight,length and head circumference.ΔZ0,except head circumference in AGA infants(ΔZ≥0 appeared after 3 month),ΔZmax appeared within the first six months.The growth velocity within the first six month was the fastest.The velocity of the catch-up growth in the weight was higher than that in the length,the median of Z score was higher in the weight.The velocity in preterm SGA infants catch-up growth was slower than that in AGA infants;in preterm AGA infants,from 3 month,6 month and 9 month,the median of Z score0,while in preterm SGA infants,the months were 9 month,12 month and 12 month.Conclusion:The fastest growing period is the early six months of life in preterm AGA infants.The catch-up growth in weight and length is unbalanced.Preterm AGA infant has greater potential than SGA infant.Z score is a better method to evaluate the growth of preterms and to provide the reference for nutritional supply for preterms.
