调查COVID-19在怀孕期间的影响

调查COVID-19在怀孕期间的影响

Based on what is known at this time, pregnant and recently pregnant women are at an increased risk for severe illness from COVID-19 compared to nonpregnant women. Additionally, pregnant women with COVID-19 are at increased risk for preterm birth and might have an increased risk of other adverse pregnancy outcomes.

CDC支持多项努力,以了解COVID-19对孕妇和婴儿的影响。这些努力中收集到的数据有利于采取直接的公共卫生行动并为临床指导方针提供信息,以照护受影响的孕妇及其婴儿。

怀孕和新生儿监测

Health departments report cases of COVID-19 to CDC, including cases among pregnant women. Health departments can also submit their data on COVID-19 cases among pregnant women and infants up to 6 months of age to CDC through an existing surveillance activity—Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET).​​ Data collected include information about the following:

  • Timing of SARS-CoV-2 infection (the virus that causes COVID-19) during pregnancy
  • COVID-19疾病严重程度
  • 妊娠预后
  • 新生儿是否确诊感染COVID-19
请参阅怀孕期间的COVID-19最新数据

母婴健康监测:COVID-19补充信息

CDC生殖健康部门正与 州和领地传染病学家委员会external icon合作,为 州、部落、地方和领地公共卫生机构提供支持和资源,以将一份COVID-19补充问卷添加到现有母婴健康监测系统中。以 妊娠风险评估监控系统(PRAMS)为例,它定期收集以人口为基础的孕前、孕期及产后的母亲行为和经验数据。该补充问卷收集COVID-19对孕期及产后妇女和婴儿的影响相关数据。调查结果将为联邦、州、地方、部落和领地公共卫生应对活动提供信息,以支持孕期及产后妇女和婴儿。


Impact of SARS-CoV-2 Infection During Pregnancy on Obstetric and Neonatal Outcomes – Icahn School of Medicine at Mt. Sinai

The Icahn School of Medicine at Mt. Sinaiexternal icon is conducting a study to determine SARS-CoV-2 seroprevalence among pregnant women, that is, the estimated percentage of pregnant women who have been infected with SARS-CoV-2, the virus that causes COVID-19. Using data from electronic health records, the study also examines associations between SARS-CoV-2 infection and adverse pregnancy outcomes. Researchers will determine the extent to which SARS-CoV-2 infection impacts pregnant women in underserved communities in New York City and will explore the role of maternal stress.

这个位于费城儿童医院(CHOP) external icon佛罗里达大学医学院-杰克逊维尔分校external icon的全国资料库旨在测量孕期感染SARS-CoV-2的当前压力,为临床护理实践提供信息,并为COVID-19预防、诊断和治疗的未来研究提供数据。该研究利用可靠的实时全国资料库获取关于COVID-19感染孕妇及其新生婴儿的信息。收集到的信息将有助于更好地了解孕期感染SARS-CoV-2可能的传播模式、风险因素、传播率以及对新生儿的影响。


怀孕及家庭传播COVID-19研究-华盛顿大学

华盛顿大学external icon正在华盛顿州金县展开一项研究,关于SARS-CoV-2流行率、家庭传播以及孕妇及其家庭成员中的抗体反应。该研究调查接受SARS-CoV-2特定IgG抗体筛查的1,000名孕妇中有症状和无症状SARS-CoV-2感染相关的不良健康后果和其他因素。该研究还预估孕妇及其家庭接触人员中的可能家庭传播以及抗体持续时间(6个月)。


怀孕和婴儿期感染SARS-CoV-2的流行病学(ESPI)网络

ESPI电子定群研究收集在三个研究地点接受产前护理的女性以及在2020年3月和2021年2月之间生产的女性的医疗档案信息。数据收集将包括以下信息:

  • 人口统计学和产妇特征
  • 健康问题
  • 产前护理
  • 妊娠并发症,包括门诊和急诊住院治疗
  • 产后护理
  • SARS-CoV-2和流感实验室检测结果
  • 妊娠预后
  • 6个月以内所选婴儿的预后

本研究旨在了解孕期以及产后六个月的SARS-CoV-2感染特征,包括六个月以内的婴儿中的感染特征。研究还希望确定COVID-19重病风险因素、说明所用的调查和未经检验的疗法,以及评估COVID-19对怀孕和婴儿预后的影响。

The ESPI Community Cohort study is a multisite collaboration designed to estimate the incidence of asymptomatic and symptomatic SARS-CoV-2 infection and understand the characteristics of SARS-CoV-2 infection in pregnant women. This includes the spectrum of disease, conditions, and risk factors for infection and developing severe illness. As a secondary objective, this study will examine the effect of COVID-19 during pregnancy on pregnancy and newborn outcomes. The study enrolls pregnant women at less than 28 weeks of pregnancy and follows them through the end of their pregnancies with weekly surveillance for SARS-CoV-2 infection and symptoms of COVID-19-like illness. Information is also collected 2-4 weeks after the end of their pregnancies, on end-of-pregnancy, infant, and postpartum outcomes.
