低出生体质量儿体质量发育及其影响因素

目的探讨低出生体质量儿(LBWI)出生12个月时体质量发育情况及影响因素。方法以2010年2月-2011年2月在本院出生后转入NICU的41例LBWI作为观察组,选择同期在本院产科出生的健康足月新生儿(NBWI)50例作为健康对照组。2组新生儿均于12个月时进行体质量发育评估,比较体质量发育情况;分析影响体质量发育的相关因素,调查内容包括姓名、性别、胎龄、日龄、出生体质量、娩出方式、家庭经济收入、父母文化程度、喂养方式、早期大小便训练等项目。结果 LBWI组在12个月时体质量显著低于NBWI组,差异有统计学意义(t=4.268,P<0.01)。回归分析显示,与体质量发育呈正相关的因素有孕周、出生体质量、娩出方式、喂养方式、母亲文化程度、早期大小便训练(Pa<0.05),其中孕周影响最大(OR=0.465)。结论 LBWI 12个月时体质量发育仍落后于NBWI,体质量发育受多种因素的影响,其中孕周影响最大。

Analysis of Weight Development of Low Birth Weight Infants and Its Influence Factors

Objective To investigate the weight development and the influence factors for low birth weight infant(LBWI) in 12 months after birth. Methods Forty-one LBWI delivered from Feb.2010 to Feb.2011 were enrolled in NICU,the Third Affiliated Hospital of Zhengzhou University,were selected as observation group.Fifty full term normal birth weight infant(NBWI),born in the Third Affiliated Hospital of Zhengzhou University in the same period,were selected as healthy control group.Infants in the 2 groups all received weight development assessment in 12 months.The weight development between 2 groups was compared and the influence factors in weight gain were analyzed.The survey included name,sex,gestational age,day age,birth weight,style of childbirth,income of family,cultural background of the parents,way of feeding,early urine training,et al. Results There was statistically significant difference between LBWI group and NBWI group in weight development in 12 months(t=4.268,P<0.01).Regression analysis showed that the factors were positively associated with weight development were gestational age,birth weight,style of childbirth,way of feeding,cultural background of mothers,early urine training including(Pa<0.05),and gestational age plays the most important role(OR=0.465). Conclusions The weight development of LBWI are inferior to NBWI in 12 month and are influenced by various factors.One of the biggest factors is gestational age.
