简要总结

This study is aiming to evaluate the effects of the COVID-19 pandemic stress on pregnancy outcomes including the sex ratio at birth.

详细描述

  • Coronavirus disease 2019 (COVID-19) is an emerging respiratory disease caused by a single-strand, positive-sense ribonucleic acid (RNA) virus, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus (Masters, 2019).
  • The sex ratio (ratio of boys to girls) at birth (SRB) is about 1.01-1.05 in most populations (Abdoli, 2020). Various influencing factors affect the SRB, including maternal stress, endocrine disruption, maternal inflammatory responses and maternal nutrition (Lipner et al., 2019).
  • These stressful life events consequently influence on maternal immunological and endocrine conditions, and the male fetuses are more vulnerable to be affected by these conditions. It is of interest that male fetus is biologically weaker and more susceptible to prenatal events and diseases than female fetuses. Hence, premature death is higher in boys than girls (Ahrenfeldt et al., 2017).
  • The recent pandemic of the coronavirus disease 2019 (COVID-19) has been known to have various impacts on pregnant women (Rasmussen et al., 2020). Placentas of infected mothers show inflammatory, vascular and thrombotic changes (Prochaska et al., 2020). Among the neonates, children and adults (Bjelosevic et al., 2017), higher morbidity and mortality of males than females were reported. It is observed that the incidence of stillbirth was significantly increased during the pandemic period than during the pre pandemic period in London, UK (Khalilet al., 2020).
  • The start of appearance of Covid 19 cases in Egypt was in March 2020, with subsequent increase in cases with its peak in May, June and July 2020, with lockdown and social and financial affection with great stress on families
