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 investigate the occurrence and related risk factors of extrauterine growth retardation (EUGR) in preterm infants. Methods Preterm infants born in our hospital in 2008 were selected for weight monitoring after birth. The incidence of EUGR was analyzed. Logistic regression was used to analyze the risk factors of EUGR. Results 184 cases of preterm infants born by body weight, intrauterine growth restriction (less than the 10th percentile of gestational age, IUGR) incidence of 20.1%, the EUGR incidence of discharge 46.2%. Perinatal-related risk factors for children with EUGR at discharge included low gestational age (OR = 6.62), low birth weight (OR = 24.02), IUGR at birth (OR 3.56), and postnatal complications (OR = 2.14), P <0.05. Conclusions The occurrence of EUGR is associated with multiple factors. The related risk factors are low gestational age, low birth weight, IUGR and complications during hospitalization.
