Abstract：
We aimed to investigate the impact of COVID-19 infection on maternal characteristics and obstetric and neonatal outcomes in a cohort of women in labor previously vaccinated who tested positive for SARS-CoV-2 infection, compared to aged-matched healthy controls. A retrospective case-control study was conducted among 66 women in labor. Clinical data were obtained from medical records. The attendance rates at childbirth and parenting classes, as well as the implementation of a birth plan, were significantly lower in the COVID-19 infection group (6.1% vs. 48.5%, <0.001; 6.1% vs. 33.3%, p = .005, respectively). Women with COVID-19 had a higher prevalence of prolonged postpartum hospital stay (33.3% vs. 9.1%, p = .016), and significantly higher prevalence of spontaneous preterm birth (27.3% vs. 1.09%, p = .006). Breastfeeding within the first 24 hr was also lower in women with COVID-19 (72.7% vs. 97.0%, p = .006). Maternal characteristics and neonatal outcomes are influenced by COVID-19 infection in vaccinated women. Complications include spontaneous preterm birth, prolonged postpartum hospital stay, and lack of breastfeeding within the first 24 hr. Childbirth education, parenting classes and implementing a birth plan may be associated with a decreased risk of COVID-19 infection.
摘要：
我们的目的是调查COVID-19感染对先前接种过SARS-CoV-2感染阳性的分娩妇女的孕产妇特征以及产科和新生儿结局的影响。与年龄匹配的健康对照相比。对66名分娩妇女进行了回顾性病例对照研究。从病历中获得临床数据。分娩和育儿班的出勤率，以及实施生育计划，在COVID-19感染组中显著更低(6.1%vs.48.5%,<0.001;6.1%vs.33.3%,分别为p=0.005)。患有COVID-19的女性产后住院时间延长的患病率较高(33.3%vs.9.1%，p=.016)，自发性早产的患病率明显更高(27.3%vs.1.09%,p=.006）。COVID-19女性在前24小时内的母乳喂养也较低（72.7%vs.97.0%,p=.006）。接种疫苗妇女的母亲特征和新生儿结局受COVID-19感染的影响。并发症包括自发性早产，产后住院时间延长，在最初的24小时内缺乏母乳喂养。分娩教育,育儿班和实施生育计划可能与COVID-19感染风险降低相关.
