目的研究不良妊娠结局与既往孕产史间的相关性。方法由专业人员采用自制调查问卷,对开封市妇产医院2013年1-9月收治的96例孕妇展开调查研究。根据孕产次予以分组,分析妊娠不良结局与既往孕产次间的相互关系。结果①既往伴孕产史的妇女,其不良妊娠率要比首次妊娠妇女更高,特别是早产儿率要比无孕产史妇女更高,差异有统计学意义(P<0.05)。②既往产次越多,孕妇引发不良妊娠结局的概率越大;既往产次为0、1、3及≥4次的产妇,其不妊娠结局率分别为9.09%、11.43%、14.28%及16.67%,对比存在统计学差异(P<0.01)。结论既往孕产史是不良妊娠的高危因素,通过推行计划生育政策,采用科学的避孕方法,减少妊娠次数,能减少妊娠不良结局发生几率。
