孕前肥胖,更容易早产吗?

2019-08-09 佚名 医咖会

孕妇肥胖会增加妊娠糖尿病、妊娠期高血压和胎儿畸形的风险,上述情况又有可能导致早产的发生。然而,孕前肥胖和早产的相关性一直存在争议,尚无定论。在一些研究中,孕前肥胖是早产的危险因素,而在另外一些研究中,两者无关系甚至是负相关关系。还有研究指出,孕前肥胖与早产的相关性可能因产妇年龄而异,在对年龄较小的母亲进行的4项研究中,孕前肥胖与早产存在负相关关系。2019年8月5日,《柳叶刀·内分泌与糖尿病学》在

孕妇肥胖会增加妊娠糖尿病、妊娠期高血压和胎儿畸形的风险,上述情况又有可能导致早产的发生。然而,孕前肥胖和早产的相关性一直存在争议,尚无定论。在一些研究中,孕前肥胖是早产的危险因素,而在另外一些研究中,两者无关系甚至是负相关关系。

还有研究指出,孕前肥胖与早产的相关性可能因产妇年龄而异,在对年龄较小的母亲进行的4项研究中,孕前肥胖与早产存在负相关关系。

2019年8月5日,《柳叶刀·内分泌与糖尿病学》在线发表了一项研究,这项基于人群的队列研究使用了美国人口统计系统中2016年和2017年全国范围内的出生证明数据。研究的对象包括所有单胎分娩且没有高血压糖尿病病史的母亲。

孕前肥胖定义为怀孕前的BMI≥30kg/m2,早产定义为小于37周分娩。研究使用了Logistic回归调整了孕妇年龄、种族或民族、胎次、教育水平、孕期吸烟、早产史、婚姻状况、婴儿性别、产前护理起始时间等,以估计早产的OR值。

研究结果

研究最终样本量为7141630,包括527637例早产(7.4%),1825112(25.6%)的女性孕前肥胖。以下情况中早产儿的比例更高:小于20岁或者大于40岁的孕妇,早产儿比例要高于其他年龄组;未婚女性高于已婚女性;教育程度低的女性高于教育程度高的女性;怀孕期间吸烟的女性高于不吸烟的女性;BMI低于18.5 kg/m2或高于40 kg/m2的女性,早产儿比例要高于其他BMI的女性。

整体人群中,孕前超重(BMI 25.0-29.9 kg/m2)或肥胖(BMI≥30 kg/m2)的女性,相比正常体重(BMI 18.5-24.9 kg/m2)的女性,早产风险显着增加(超重:调整后OR = 1.02 [95%CI 1.01-1.03];肥胖:调整后OR = 1.18 [95%CI 1.18-1.19]);早产的调整后OR值随着肥胖程度的增加而增加。与正常体重相比,体重不足与早产也具有显着相关性。详见表2。

孕前肥胖与早产的相关性,因产妇年龄和种族而有所不同(Pinteraction < 0.0001)。分层分析显示,孕前肥胖与早产的相关性,在25岁以下女性和非西班牙裔黑人女性中是相反的。

本研究进一步做了年龄X种族的分析,观察到年龄的交叉影响。在非西班牙裔白人中,20岁以下的女性孕前肥胖与早产呈负相关,但20岁及以上女性孕前肥胖与早产呈正相关。在西班牙裔女性中,20岁以下的女性孕前肥胖与早产无相关性,但20岁及以上女性孕前肥胖与早产呈正相关。在非西班牙裔黑人中,30岁以下的女性孕前肥胖与早产呈负相关,但30岁及以上女性孕前肥胖与早产呈正相关。

在所有种族中,早产的OR值随着年龄增加而增加。

结论

本研究发现,一般人群中,母亲孕前肥胖与早产风险有显着相关性,但是该相关性随着母亲年龄和种族/民族而有所不同。提供与早产有关的孕前和产前咨询的医生,应该考虑到这些因素。

还需要更多研究来探讨母亲孕前肥胖与早产风险的相关性存在差异的潜在机制。此外,早产风险预测模型应该更精细地考虑到母亲年龄、种族/民族等因素。
