摘要
目的研究妇女人工流产次数对再孕后发生早产儿概率的关系。方法对我院2010年1月至2012年12月分娩的产妇其早产儿的发生率与其既往人工流产史的关系进行了回顾性分析研究。采用卡方检验进行统计学分析。结果有3次或3次以上人工流产的产妇组与无人工流产史的产妇组其再孕后早产儿发生率χ2=7.3279,P=0.01-0.005呈显著性差异,而有1次或2次人工流产史组的产妇与无人工流产史的产妇再孕后发生早产儿的概率χ2=1.41844,P=0.25-0.01;χ2=0.9148,P=0.5-0.25无明显差异。结论有1次或2次人工流产史对再孕后发生早产儿的概率虽无显明影响但人工流产次数过多可引起早产儿发生概率明显增加。
Objective To study the relationship between the frequency of artificial abortion and the probability of premature babies after pregnancy. Methods Lying-in women in our hospital from January 2010 to December 2012 were selected and the relation between the incidence rate of their premature babies and their history of artificial abortion was analyzed retrospectively, while was analyzed statistically by chi-square test. Results There was significant difference in the frequency of artificial abortion after pregnancy （χ2=7.3279, P=-0.01-0.005） between the maternal group with 3 or more times artificial abortion and the other group with no abortion history, but with no significant difference between lor 2 times artificial abortion group and no abortion history group （χ2= 1.41844, P=0.25-0.01; χ2=0.9148, P=-0.5-0.25）. Conclusion Although I or 2 times abortion histories had no effects on the probability of premature babies after pregnancy; too many abortions can clearly increase probability of premature babies.
