A randomized Controlled Trial on the Relationship Between Prenatal Anxiety And Adverse Pregnancy Outcomes

目的:探讨产前焦虑与不良妊娠结局之间的关系;寻找一种有效降低孕妇产前焦虑的干预方法。方法:采用随机对照试验从2008年1-12月期间在我院产检的孕妇中选择具有产前焦虑症状者200名,并随机分成干预组和对照组,干预组采用积极的心理疏导方式定期进行干预,对照组采用常规的产检方法,追踪随访至产后,并记录妊娠结局。结果:干预组新生儿出生体重、Apgar 1 min和5 min评分较对照组高,分娩前焦虑水平、产后出血量、剖宫产比例以及早产的比例显著低于对照组(P<0.05)。结论:孕妇产前焦虑对妊娠结局具有不良影响,积极的心理疏导方式可有效地降低产前焦虑水平。

Objective To explore the relationship between prenatal anxiety and adverse pregnancy outcomes and to find an effective intervention method to decrease the occurence of prenatal anxiety.Methods A randomized controlled trial was employed in 200 pregnant women with prenatal anxiety,who were selected from all the pregnant women in our hospital from January to December in 2008.The pregnant women with prenatal anxiety were randomly divided into intervention group and control group,the intervention group were treated with positive psychological guidance and the control group were treated as normal pregnant women.All the cases were followed and the pregnant outcomes were recorded.Results The newborn infant weight,the Apgar score at 1 min and 5 min in intervention group were all significantly higher than those of control group（P0.05）.Meanwhile,the anxiety degree before delivery,blood loss after delivery,the proportion of abdominal delivery and preterm in intervention group were all significantly lower than those of control group（P0.05）.Conclusion Prenatal anxiety may have adverse effect on the pregnancy outcome,and the positive psychological guidance may be helpful for relieving the pregnant women from prenatal anxiety.
