84例早产适于胎龄儿第一年体格追赶生长纵向评估

Longitudinal study of the physical catch-up growth in 84 preterm appropriate for gestational age infants

摘要:

目的：分析早产适于胎龄儿1岁以内的追赶生长特点，探讨其追赶生长规律。方法：选择84名胎龄28～36周的早产适于胎龄儿（男44例，女40例）作为研究对象，对其0～12月内的体重、身长及头围分别按实际月龄足月儿生长标准和纠正月龄标准进行Z评分评估并分析。结果：早产适于胎龄儿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实际月龄0～3月，体重追赶速度优于身长追赶速度。结论：生后前3个月是早产适于胎龄儿的快速生长期；体重与身长的变化存在不平衡性。

Abstract:

OBJECTIVE: To study the growth rhythm of preterm appropriate for gestational age (AGA) infants by investigating their physical catch-up growth characteristics. METHODS: Eighty-four preterm AGA newborns (44 males and 40 females) with gestational ages between 28-36 weeks were enrolled. The weight, length and head circumference were evaluated by Z score according to the criterions of actual and corrected ages. RESULTS: The preterm infants had the catch-up growth in weight, length and head circumference in the first year of life. The growth velocity within the first three months was the highest. The velocity in the weight catch-up was higher than that in the length. CONCLUSIONS: The fastest growing period is the early three month of life in preterm AGA infants. The catch-up growth in weight and length is unbalanced.
