摘　　要：目的调查发生前置胎盘的相关危险因素，为其预防和治疗提供理论依据。方法收集420例前置胎盘和1260例正常孕妇的临床资料，建讧数据库，应用Logistic回归分析办法分析临床相关危险因素。结果剖宫产次数（OR=2．656，95％CI：1．457～5．536）、双胎及多胎妊娠（OR=2．325，95％CI：1．643～5．673）、子宫内膜炎（OR=4．646，95％C1：1．642～6．534）、吸烟或被动吸烟（OR=3．453，95％CI：1．653—7．562）、流产次数（OR=2．267，95％CI：1．785～6．545）与引发前置胎盘密功相关，并且前置胎盘可以导致胎赢粘连、胎盘植入、产后出血、早产、死胎等。结论剖宫产次数、吸烟或被动吸烟、流产次数、双胎及多胎妊娠、子宫内膜炎是引发前置胎盘的相关危险因素。Objective To investigate and analyse the clinical associated risk factors which affect the placenta praevia, provi- ding theoretical basis for early prevention and treatment of this disease. Methods Clinical data of 420 cases, diagnosed as having pla- centa praevia, were collected to establish database, and logistic regression analysis was conducted to analyze the clinical associated risk factors. Results The number of cesarean section （ OR = 2. 656, 95%0 CI： 1. 457 - 5. 536 ） , twin and muhiple pregnancy （ OR = 2. 325, 95% CI： 1. 643 -5. 673）, endometritis （ OR =4. 646, 95% CI： 1. 642 -6. 534） , smoking （ OR =3. 453, 95% CI： 1. 653 - 7. 562 ） , number of abortion （OR = 2. 267, 950/0 CI： 1. 785 -6. 545 ） , were closely related to placenta praevia and placenta praevia can lead to adherent placenta, placenta accreta, postpartum hemorrhage, premature birth, stillbirth and other adverse pregnancy out- comes. Conclusions Uterine incision deliver：c, smoking, abortion, multiple pregnancy, and endometritis arc related risk factors of placenta praevia.
