Background & Objective: The study aims to determine the adverse effects of a mild COVID-19 infection on maternal and neonatal outcomes in pregnant women living in the eastern part of Tehran.Materials & Methods: In this prospective cohort study, we followed two groups of pregnant women until term and their pregnancy and neonatal outcomes. RT-PCR (reverse transcriptase polymerase chain reaction) positive tests of nasopharyngeal swabs were confirmed in one group, where at least three signs and symptoms associated with COVID-19, and/or chest CT scans identified highly specific findings for the disease were present. The control group is composed of healthy pregnant women tested negative for COVID-19.Results: The study included 319 pregnant women (108 with mild COVID-19 infection and 211 healthy). A higher percentage of mothers with mild COVID-19 infection had preterm births (47.9% vs. 30%, p=0.007), and their neonates required hospitalization more often (45.8% vs. 22.6%, p<0.001). PTB was positively associated with maternal hypertension (relative risk (RR): 5.40), mild COVID-19 infection (RR: 2.05), and older age (RR: 1.05). Among the risk factors for neonatal hospitalization, PTB (RR: 5.94), maternal hypertension (RR: 2.74), and mild COVID-19 infection during pregnancy (RR: 2.57) were significant.Conclusion: The outcomes of pregnancy are significantly impacted by maternal infection with COVID-19, even if it is mild. Preterm births are more likely to happen in mothers with mild COVID-19 infection, and neonates need more hospitalizations.
