A University of Oxford study of over 4000 pregnant women indicates that severe COVID in pregnancy increases the risk of pre-labour caesarean birth, a very or extreme preterm birth, stillborn birth, and the need for admission to a neonatal unit.
The study, published in Acta Obstetricia et Gynecologica Scandinavica, included 4436 pregnant women hospitalised in the UK with symptomatic COVID from March 1, 2020 to October 31, 2021, of whom 13.9% of had severe COVID. As well as having increased risks of adverse pregnancy-related outcomes, women with severe infection were more likely to be aged 30 years or over, be overweight or obese, be of mixed ethnicity, or have gestational diabetes compared with those with mild or moderate infection.
“This new analysis shows that certain pregnant women admitted to a hospital with COVID face an elevated risk of severe disease. However, it shows once again the strongly protective effect of vaccination against severe disease and adverse outcomes for both mother and baby,” said senior author Marian Knight, FMedSci, of the University of Oxford. “This study emphasises the importance of ensuring that interventions to promote vaccine uptake are particularly focused towards those at highest risk.”
