To determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, the cause of COVID-19 disease) exposure in pregnancy, compared to non-exposure, is associated with infection-related obstetric morbidity.
We conducted a multicentre prospective study in pregnancy based on a universal antenatal screening program for SARS-CoV-2 infection. Throughout Spain 45 hospitals tested all women at admission on delivery ward using polymerase-chain-reaction (PCR) for COVID-19 since late March 2020. The cohort of positive mothers and the concurrent sample of negative mothers was followed up until 6-weeks post-partum. Multivariable logistic regression analysis, adjusting for known confounding variables, determined the adjusted odds ratio (aOR) with 95% confidence intervals (95% CI) of the association of SARS-CoV-2 infection and obstetric outcomes.
Preterm delivery (primary), premature rupture of membranes and neonatal intensive care unit admissions.
Among 1009 screened pregnancies, 246 were SARS-CoV-2 positive. Compared to negative mothers (763 cases), SARS-CoV-2 infection increased the odds of preterm birth (34 vs 51, 13.8% vs 6.7%, aOR 2.12, 95% CI 1.32-3.36, p = 0.002); iatrogenic preterm delivery was more frequent in infected women (4.9% vs 1.3%, p = 0.001), while the occurrence of spontaneous preterm deliveries was statistically similar (6.1% vs 4.7%). An increased risk of premature rupture of membranes at term (39 vs 75, 15.8% vs 9.8%, aOR 1.70, 95% CI 1.11-2.57, p = 0.013) and neonatal intensive care unit admissions (23 vs 18, 9.3% vs 2.4%, aOR 4.62, 95% CI 2.43-8.94, p < 0.001) was also observed in positive mothers.
This prospective multicentre study demonstrated that pregnant women infected with SARS-CoV-2 have more infection-related obstetric morbidity. This hypothesis merits evaluation of a causal association in further research.
为了确定孕期感染严重急性呼吸综合征冠状病毒2（SARS-CoV-2，新冠病毒病的病原体）与未感染者相比，是否与感染相关的产科发病率有关。
我们基于一项针对SARS-CoV-2感染的通用产前筛查计划，开展了一项多中心前瞻性孕期研究。自2020年3月下旬起，西班牙的45家医院对所有入住产房的妇女使用聚合酶链反应（PCR）检测新冠病毒。对阳性母亲队列和阴性母亲的同期样本进行随访，直至产后6周。多变量逻辑回归分析在对已知混杂变量进行调整后，确定了SARS-CoV-2感染与产科结局关联的调整优势比（aOR）及95%置信区间（95%CI）。
早产（主要指标）、胎膜早破和新生儿重症监护病房收治情况。
在1009例接受筛查的孕妇中，246例SARS-CoV-2呈阳性。与阴性母亲（763例）相比，SARS-CoV-2感染增加了早产几率（34例对51例，13.8%对6.7%，aOR 2.12，95%CI 1.32 - 3.36，p = 0.002）；感染妇女的医源性早产更常见（4.9%对1.3%，p = 0.001），而自发性早产的发生率在统计学上相似（6.1%对4.7%）。足月胎膜早破风险增加（39例对75例，15.8%对9.8%，aOR 1.70，95%CI 1.11 - 2.57，p = 0.013），阳性母亲中新生儿重症监护病房收治情况也增加（23例对18例，9.3%对2.4%，aOR 4.62，95%CI 2.43 - 8.94，p < 0.001）。
这项前瞻性多中心研究表明，感染SARS-CoV-2的孕妇有更多与感染相关的产科发病率。这一假设值得在进一步研究中评估因果关系。
