JAMA子刊:孕妇早产史与子代先天性畸形的关系

2022-07-30 liangying MedSci原创

母亲的PTB病史增加了后代出生CAs的风险,而相关机制尚待阐明,这些发现可能有助于确定CAs高危新生儿。

先天性畸形(CAs)是婴儿死亡的主要原因,在2017年占美国婴儿死亡的20%以上。已经确定了几种先天性畸形的父母相关风险因素,包括吸烟史和孕前糖尿病等。然而,关于母亲既往妊娠结局与CAs风险之间关系的数据很少。为了进一步阐明潜在的危险因素,本研究评估了孕妇的早产史(PTB)和后代CAs之间的关系。

这项以人群为基础的回顾性队列研究使用了美国国家生命统计系统2016年1月1日至2019年12月31日的出生数据,包括所有单胎活产的女性。数据分析于2022年2月1日至2月15日进行。由于确定的数据是公开的,复旦大学儿童医院的机构审查委员会不需要伦理审批。本研究是根据《加强流行病学观察性研究报告指南》(STROBE)进行报道的。

从出生证明中检索到PTB和12种CAs亚型的母亲病史信息。由于结果发生率低,比例以千分之几(‰)表示。母亲PTB病史与新生儿CAs的相关性被估计为风险差异、粗比值比(ORs)和校正ORs(aOR)与95%CI。根据基线特征进行分层分析。对潜在的混杂因素进行了调整,包括母亲年龄、种族和民族、教育水平、婚姻状况、胎次、孕前和孕期吸烟、孕前体重指数类别、开始产前护理的时间、孕前高血压、孕前糖尿病、妊娠高血压、妊娠糖尿病和婴儿性别。所有P值均为双侧,P <0.05被认为具有统计学意义。使用Stata版本15.0(StataCorp LLC)进行统计分析。

最终分析包括14774946对单胎活产母婴,母亲的平均年龄为28.86岁。CAs患病率为3.19‰。 有PTB病史的母亲所生的新生儿比没有PTB病史的母亲所生的新生儿的患病率高。在完全调整后,对于PTB的母亲病史,CAs的OR为1.47(95%CI,1.42-1.54)。对于CAs的特定亚型,除无脑外,PTB的母亲病史与几乎所有亚型的风险增加有关。

母亲PTB病史与后代先天性畸形风险的亚组分析

按母亲年龄、种族、教育水平、胎次、孕前和孕期吸烟、产前护理开始时间、孕前体重指数、孕前高血压、孕前糖尿病、妊娠高血压、妊娠糖尿病和新生儿性别进行亚组分析。结果发现,有PTB病史的母亲所生的新生儿在完全适应后的所有亚组中均有较高的CAs风险。

这项研究的结果表明,母亲的PTB病史增加了后代出生CAs的风险,而相关机制尚待阐明,这些发现可能有助于确定CAs高危新生儿。
