摘要
目的：分析不同类型自发性早产的相关危险因素。方法676例自发性早产产妇中，早产发生在孕32周之前的108例（早发组），孕32～36＋6周的568例（轻型组）。正常足月分娩954例作为对照（对照组）。分析产妇的相关资料和早产的危险因素。结果 Logistic回归分析显示，早发组自发性早产的相关因素包括产次、流产史、双胎妊娠、胎位不正、胎膜早破、胎盘异常及产前发热（ P＜0．05或P＜0．01）。轻型组自发性早产的相关因素包括产次、流产史、双胎妊娠、胎位不正、胎膜早破、妊娠期高血压、宫颈环扎术后、羊水异常及产前发热（ P＜0．05或P＜0．01）。结论早产是多种因素联合作用的结果，早期及轻型自发性早产的危险因素不完全相同，孕期应尽早识别并积极干预早产的相关危险因素，以减少早产的发生。

Conclusion Premature birth is related to many complicated factors .The risk factors for spontaneous preterm birth are not all the same in pregnant women with different gestational weeks .To reduce the incidence of spontaneous preterm birth ,attention should be paid to early identifying and actively intervening the risk factors for spontaneous preterm birth .
