早产儿宫外生长迟缓发生情况及相关危险因素分析

Extrauterine growth retardation in premature infants and the risk factors:a retrospective study

目的探讨早产儿宫外生长迟缓(EUGR)发生情况及相关危险因素。方法选择本院2008年出生的早产儿,生后进行体重监测,分析EUGR发生情况,应用Logistic多元回归分析EUGR的相关危险因素。结果 184例早产儿出生时以体重计,宫内生长受限(低于同胎龄第10百分位点,IUGR)的发生率20.1%,出院时EUGR的发生率46.2%。出院时表现为EUGR的患儿围产期有关的危险因素包括低胎龄(OR=6.62)、低出生体重(OR=24.02)、出生时IUGR(OR=3.56)及生后并发症(OR=2.14),P均<0.05。结论 EUGR的发生与多因素有关,其相关的危险因素有低胎龄、低体重、IUGR及住院期间并发症。

Objective To study the incidence and the risk factors of premature neonates associated with extrauterine growth retardation （EUGR）. Methods 184 premature neonates t^orn in the Maternal and Childreng Hospital, Dalian in 2008 were monitored the weights. The incidence of EUGR was calculated and logistic regression analysis was applied to investigate the risk factors correlating with EUGR. Results By weight, the incidence of intrauterine growth restriction retardation （defined as measured growth parameters 〈 10th percentile on the growth curves, IUGR） of the 184 infants was 20. 1% on birth, the incidence of postnatal growth retardation was 46. 2% at discharge. The risk factors correlating with EUGR were low gestational age （OR = 6.62）, low birth weight （OR = 24.02）, intrauterine growth restriction （ OR = 3.56 ）, the complications after birth （ OR = 2. 14 ）, P 〈 0. 05. Conclusion The causes of EUGR are muti-factorial, the risk factors for EUGR were low gestational age, low birth weight, intrauterine growth restriction on birth, and the complications after birth.
