RESUMEN
OBJECTIVE: Pregnant women infected with SARS-CoV-2 are more likely to have obstetric complications, particularly preterm births, increasing the likelihood of maternal and neonatal morbidity and mortality. We tested the hypothesis by using a multivariable logistic regression analysis to take into account the effects of known confounding variables. PATIENTS AND METHODS: A retrospective cohort study targeted a random sample of 89 preterm deliveries at the Obstetrics and Gynecology Department, Zagazig University Hospital, from January 2022 to April 2022, who fulfilled the selection criteria using a pretested, well-structured questionnaire that was composed of three main parts. The collected data were coded and analyzed using appropriate statistical methods. RESULTS: This retrospective cohort study included 89 participants with a mean age of 26.6 years, 44.9% were middle-educated, 73% were not working, and the majority were not smoking or abusing substances. Regarding the frequency of COVID-19, dividing the studied participants into two groups, 22.5% had been infected, and there was no statistically significant difference between the two groups as regards the demographic characteristics, but smoking statistically increased the smoking (p-value = 0.034). Regarding the relationship between the history of COVID-19 and the past and present obstetric histories, there was no statistically significant difference between them. Even though the SARS-CoV-2 infection is significant (p-value = 0.037), pregnant women who are COVID-19 positive are more likely to have a cesarean section (16/80) than pregnant women who test positive. CONCLUSIONS: Pregnant and preterm women were more likely to get SARS-CoV-2 if they smoked, had comorbidities, or were overweight or obese. Among COVID-19 preterm pregnancies, substance misuse and comorbidity were risk factors for a poor neonatal outcome, while women who had a previous history of PPH, were smokers, or had comorbid illnesses had a significantly increased risk of having a poor maternal outcome.
