Overview

Background The current study evaluated the hypothesis that the COVID-19 pandemic is associated with higher stillbirth but lower neonatal mortality rates. Methods We compared three epochs: baseline (2016–2019, January–December, weeks 1–52, and 2020, January–February, weeks 1–8), initial pandemic (2020, March–December, weeks 9–52, and 2021, January–June, weeks 1–26), and delta pandemic (2021, July–September, weeks 27–39) periods, using Alabama Department of Public Health database including deliveries with stillbirths ≥20 weeks or live births ≥22 weeks gestation. The primary outcomes were stillbirth and neonatal mortality rates. Results A total of 325,036 deliveries were included (236,481 from baseline, 74,076 from initial pandemic, and 14,479 from delta pandemic period). The neonatal mortality rate was lower in the pandemic periods (4.4 to 3.5 and 3.6/1000 live births, in the baseline, initial, and delta pandemic periods, respectively, p  < 0.01), but the stillbirth rate did not differ (9 to 8.5 and 8.6/1000 births, p  = 0.41). On interrupted time-series analyses, there were no significant changes in either stillbirth ( p  = 0.11 for baseline vs. initial pandemic period, and p  = 0.67 for baseline vs. delta pandemic period) or neonatal mortality rates ( p  = 0.28 and 0.89, respectively). Conclusions The COVID-19 pandemic periods were not associated with a significant change in stillbirth and neonatal mortality rates compared to the baseline period. Impact The COVID-19 pandemic could have resulted in changes in fetal and neonatal outcomes. However, only a few population-based studies have compared the risk of fetal and neonatal mortality in the pandemic period to the baseline period. This population-based study identifies the changes in fetal and neonatal outcomes during the initial and delta COVID-19 pandemic period as compared to the baseline period. The current study shows that stillbirth and neonatal mortality rates were not significantly different in the initial and delta COVID-19 pandemic periods as compared to the baseline period.
