Purpose : The purpose of this study was to identify the risk factors for intrauterine fetal death (IUFD).
Methods : We carried out a case control retrospective study, at the Chonnam National University Hospital, Korea. We included all pregnant women diagnosed as singleton IUFD in pregnancies of 28 weeks of gestation or more, admitted to the hospital from Jan 2003 to Dec 2007. There were 53 cases of singleton IUFD and 3,298 cases of singleton live birth during that period. The incidence, age distribution, and prevalent gestational weeks were analysed. The risk factors were analyzed by using odds ratio, Student’s t test, and Chisquare test. Logistic regression analysis was applied to determine independent risk factors.
Results : The overall incidence of IUFD was 1.6%. The age distribution of mother with IUFD was highest in the age group of 20 year old or less (5.3%). IUFD was the most prevalent at 28-32 weeks of gestation (41.5%). Significant risk factors were maternal body weight just before delivery, weight gain during pregnancy, and abruptio placentae. The independent risk factors were weight gain during pregnancy (β =0.002, P =0.000) and abruptio placentae (β =-0.067, P =0.000).
Conclusion : Lower maternal body weight just before delivery, lower weight gain during pregnancy, and abruptio placentae are factors significantly associated with IUFD. Further investigations are needed to understand the complex etiology of stillbirth.
