BACKGROUND The SARS-CoV-2 pandemic and its influence on peripartum processes worldwide led to issues in breastfeeding support. RESEARCH AIM The aim of this study was to describe breastfeeding behavior and peripartum in-hospital management during the pandemic in Germany and Austria. METHODS This study was a descriptive study using a combination of secondary longitudinal data and a cross-sectional online survey. Registry data from the prospective multicenter COVID-19 Related Obstetric and Neonatal Outcome Study (CRONOS) cohort study (longitudinal, medical records of 1,815 parent-neonate pairs with confirmed SARS-CoV-2 infection during pregnancy) and a cross-sectional online survey of CRONOS hospitals' physicians (N = 67) were used for a descriptive comparison of feeding outcomes and postpartum management. RESULTS In 93.7% (n = 1700) of the cases in which information on the neonate's diet was provided, feeding was with the mother's own milk. Among neonates not receiving their mother's own milk, 24.3% (n = 26) reported SARS-CoV-2 infection as the reason. Peripartum maternal SARS-CoV-2 infection, severe maternal COVID-19 including the need for intensive care unit (ICU) treatment or invasive ventilation, preterm birth, mandatory delivery due to COVID-19, and neonatal ICU admission were associated with lower rates of breastfeeding. Rooming-in positively influenced breastfeeding without affecting neonatal SARS-CoV-2 frequency (4.2% vs. 5.6%). CRONOS hospitals reported that feeding an infant their mother's own milk continued to be supported during the pandemic. In cases of severe COVID-19, four of five hospitals encouraged breastfeeding. CONCLUSION Maintaining rooming-in and breastfeeding support services in the CRONOS hospitals during the pandemic resulted in high breastfeeding rates.

Covid-19 相关产科和新生儿结果研究 (CRONOS) 中的母乳喂养行为。

背景 SARS-CoV-2 大流行及其对全球围产期过程的影响导致了母乳喂养支持方面的问题。研究目的 本研究的目的是描述德国和奥地利大流行期间的母乳喂养行为和围产期住院管理。方法 本研究是一项描述性研究，结合了二次纵向数据和横断面在线调查。来自前瞻性多中心 COVID-19 相关产科和新生儿结局研究 (CRONOS) 队列研究（1,815 对怀孕期间确诊 SARS-CoV-2 感染的父母-新生儿的纵向医疗记录）的登记数据以及一项横断面在线调查CRONOS 医院的医生（N = 67）被用来对喂养结果和产后管理进行描述性比较。结果 在提供新生儿饮食信息的案例中，93.7%（n = 1700）是用母亲自己的乳汁喂养的。在未接受母乳的新生儿中，24.3% (n = 26) 报告称其原因是 SARS-CoV-2 感染。围产期孕产妇 SARS-CoV-2 感染、严重孕产妇 COVID-19（包括需要重症监护病房 (ICU) 治疗或有创通气）、早产、因 COVID-19 强制分娩以及新生儿 ICU 入住均与较低的死亡率相关。哺乳。母婴同室对母乳喂养产生积极影响，但不影响新生儿 SARS-CoV-2 频率（4.2% 与 5.6%）。克罗诺斯医院报告称，在大流行期间，继续支持用母亲的母乳喂养婴儿。对于严重的 COVID-19 病例，五家医院中有四家鼓励母乳喂养。结论 在大流行期间，克罗诺斯医院维持母婴同室和母乳喂养支持服务导致了较高的母乳喂养率。
