Pregnant women who were hospitalized during the same period without COVID-19 were the control group (Group 2). Maternal and neonatal outcomes were compared between the groups.<\/jats:p><jats:p>\n            Results\u2003A total of 230 pregnant women and their infants were assessed. Group 1 (n\u2009=\u200974) had significantly higher rates of diabetes mellitus and hypertension than Group 2 (n\u2009=\u2009156; p\u2009=\u20090.015 and 0.014, respectively). Premature birth and cesarean section rates were also significantly higher in Group 1 than in Group 2 (p\u2009=\u20090.001 and 0.040, respectively). While the rate of iatrogenic preterm birth was significantly higher in Group 1, the rate of spontaneous preterm birth was significantly higher in Group 2 (p\u2009=\u20090.049). Infants born to COVID-19-positive mothers had lower median gestational age, birth weight, and Apgar scores (p\u2009&lt;\u20090.01). There was no significant difference between the groups in terms of the results of cord blood gas analysis (p\u2009&gt;\u20090.05). The rate of admission to the neonatal intensive care unit (NICU) and need for mechanical ventilation was significantly higher in infants of COVID-19-positive mothers (p\u2009&lt;\u20090.05 for both). The length of stay in the NICU was also significantly longer for the infants of COVID-19-positive mothers (p\u2009&lt;\u20090.05). Birth weights decreased due to increased cases of iatrogenic preterm births (p\u2009&lt;\u20090.05). However, ponderal indices (PIs) of newborns of pregnant COVID-19 mothers did not differ at birth (p\u2009&gt;\u20090.05).<\/jats:p><jats:p>\n            Conclusion\u2003COVID-19 is associated with low Apgar scores, increased risk of premature birth complications, and maternal comorbidities, with no effect on the PI and proportionate growth of the infant at birth.<\/jats:p><jats:p>\n            Key
