ABSTRACT
OBJECTIVES: Intrauterine growth restriction(IUGR) accounts for significantiy increased perinatal mortality and neonatal morbidity rates. The Purpose of this study is to investigate the association between some of the risk factors and the incidence of fetal growth restriction. PATIENTS AND METHOD: The retrospective survey of obstetric records of 2188 mothers, who delivered between July, 1995 and June, 1998, was carried out in Hanyang University Kuri Hospital, with the following inclusion criteria: Korean, singleton pregnancy with live birth and a gestational age of more than 32 weeks. RESULTS AND CONCLUSION: 1) The incidence rate for IUGR was 4,7% during the period of 1995 through 1998. 2) 41.2% of IUGR was due to unknown causes, 58.8% of IUGR was due to known. Among known causes the maternal factor was 40.2%, the placenta factor was 14.7%, and the fetal anomaly was 4%. 3) Among maternal factors, pregnancy induced hypertension was the most common cause. 4) The incidence of IUGR was higher in primiparous women and in female babies. 5) The IUGR group showed lower Apgar scores at 1 and 5 minutes than control group,
