标题： Birthweight Declined During the Pandemic and It Is Falling Further Post-pandemic

摘要： 近期文献报告了关于疫情期间出生体重是否下降的矛盾证据。在这篇论文中，我们使用纽约医院的住院分娩出院数据，并以多种方式为这一持续争论做出贡献。首先，我们证实疫情期间出生体重下降了7克（克）。其次，我们提供了第一个实证证据，表明疫情之后，不仅出生体重没有恢复到疫情前的水平，反而比疫情前低了17克。第三，在疫情后的几年里，因分娩而住院的母亲面临更高的死亡风险的可能性增加了27%，严重疾病的风险增加了8%。出生体重的变化可能会对人群的健康、寿命和福祉产生深远影响。因此，了解COVID-19对出生体重的全面影响是一项重要且及时的工作。未来的研究需要检验我们的结果是否是由出生体重和并发症的真实变化所驱动，或者是由医疗提供者受到（经济或其他方面）诱导而不同地报告出生体重所导致。 显示英文摘要

摘要： Recent literature reports mixed evidence on whether birthweight has decreased during the pandemic. In this paper, we use New York's hospital inpatient discharge data and contribute to this ongoing debate in multiple ways. First, we corroborate that birthweight has declined during the pandemic by 7g (grams). Second, we provide the first empirical evidence that, after the pandemic, not only birthweight has not reverted to the pre-pandemic levels, but it has fallen lower, 17g below the pre-pandemic levels. Third, in the post-pandemic years, mothers who are hospitalized to give birth are 27% more likely to be at a higher mortality risk and 8% more likely to have a higher severity of illness. Disruptions to birthweight could have far-reaching consequences for the health, longevity, and well-being of the population. Therefore, understanding the full scope of COVID-19's influence on birthweight is a vital and timely practice. Future research is needed to test whether our results are driven by true underlying changes in birthweight and complications or by healthcare providers being induced (financially or otherwise) to report birthweight differently.
