COVID‐19 lockdowns affected birthing outcomes in a regional New South Wales Health District

IntroductionThe 400 000 residents of the Illawarra Shoalhaven Local Health District (ISLHD) experienced two distinct lockdowns aimed at mitigating the transmission of severe acute respiratory syndrome coronavirus 2 infection. Analysing effects of these lockdowns on maternal and neonatal outcomes presents a valuable opportunity to assess the impact of pandemic‐level restrictions on maternal and neonatal outcomes.AimEvaluate the impacts of restrictions from two lockdown periods on maternal, birthing, and neonatal outcomes within a regional local health district.Materials and MethodsThe study included 22 166 women who gave birth within ISLHD between 2017 and 2022. Groups included for analysis: Control Group – mothers pregnant before the pandemic (conception before 3 April 2019); Exposure Group 1 – mothers pregnant during the first lockdown (conception date 22 January 2020 to 5 May 2020); and Exposure Group 2 – mothers pregnant during the second lockdown (conception date 30 April 2021 to 13 Sep 2021).ResultsOdds of adverse birthing outcomes including non‐reassuring fetal status (odds ratio (OR) 1.34; 95% CI 1.14–1.56 and OR 1.20; 95% CI 1.03–1.40), and postpartum haemorrhage (OR 2.04; 95% CI 1.73–2.41 and OR 1.74; 95% CI 1.48–2.05) were substantially increased in Exposure Groups 1 and 2, respectively. Gestational diabetes, gestational hypertension, low birth weight and admission to neonatal intensive care rates improved.ConclusionsPregnant women exposed to pandemic restrictions within ISLHD had decreased odds of adverse antenatal and neonatal outcomes, but increased odds of poor peripartum outcomes.
