JAMA Intern Med:孕吐别烦恼,可降低流产的风险

虽然晨吐是个不愉快的经历,但是它似乎是健康怀孕的一个部分。然而,到目前为止,关于此的研究尚少。据发表于JAMA Internal Medicine的一项新的研究表明,孕妇晨吐对胎儿有保护作用,可降低流产的风险。

研究人员所使用的数据来自阿司匹林在妊娠和生殖的影响(EAGeR)试验。EAGeR是用来测试低剂量阿司匹林对过去曾有一次或两次流产经历女性影响而设计的试验。

所有参与者均记日记以记录其怀孕2-8周之间恶心的感觉。此外,研究人员每月还对参与者的症状进行的问卷调查,直到怀孕的第36周。

既往探究孕吐保护作用的研究依赖于女性怀孕后期或其流产后对孕吐的回忆。该研究首次实时跟踪了孕妇孕吐的情况。

EAGeR试验共纳入了797名孕妇,188次流产事件。孕期第8周时,57.3%的孕妇有恶心症状,26.6%的孕妇有恶心和呕吐。

分析数据显示,有过孕吐的女性较没有呕吐或恶心的女性流产的可能低50-75%。

研究人员表示,该研究从女性怀孕早期,立即受孕后开始,确认恶心和呕吐的症状与流产风险较低之间的具有关联。

结果表明,晨吐似乎是健康怀孕的一个标志,具有某些保护作用。虽然这项研究在规模和质量上是目前最大最高的,但是仍需更多的研究继续研究。

该研究中所有的研究对象均有流产史,所以并不能代表所有的孕妇。此外,本研究并没有确定孕吐究竟如何降低流产的风险。
