Birth Outcomes of Pregnant Women Infected with COVID-19 in Highland Areas of China from 2020 to 2022: A Retrospective Analysis

Abstract

Purpose: To explore the effect of coronavirus disease 2019 (COVID-19) infection on neonates in plateau regions.

Methods: Cases of newborns born to pregnant women infected with COVID-19 who received prenatal care or treatment at the Women and Children's Hospital of the Tibet Autonomous Region and the Lhasa People's Hospital between January 2020 and December 2022 (infected group) and newborns born to healthy pregnant women (non-infected group) who were included by age, underlying disease and length of hospital stay were retrospectively collected. According to the inclusion and exclusion criteria, 381 patients in the infected group and 314 patients in the non-infected group were included in the study.

Results: The results of multivariate analysis showed that admission to the neonatal intensive care unit (OR = 3.342, 95% CI = 1.564-6.764), shortness of breath (OR = 2.853, 95% CI = 1.789-3.154), irregular breathing (OR = 2.465, 95% CI = 1.879-4.112) and neonatal jaundice (OR = 2.324, 95% CI = 1.989-2.445) were the factors influencing the low Apgar scores of neonates in the infected group (all P < 0.05).

Conclusion: Neonates born to pregnant women infected with COVID-19 had lower Apgar scores and higher incidences of complications, such as shortness of breath, groaning, irregular breathing and neonatal jaundice, than newborns born to pregnant women not infected with COVID-19.
