Insights

Maternal SARS-CoV-2 infection during pregnancy may impact infant neurobehavioral development, with neonates showing lower scores in several domains, particularly fine motor skills. Further research is needed to confirm these findings.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Development
  • Infectious Diseases

Background:

  • Limited research exists on SARS-CoV-2 effects on infant neurobehavioral development.
  • Previous studies focused on general populations and pregnant women, not specifically infant outcomes.
  • Understanding SARS-CoV-2 impact on neurodevelopment is crucial for maternal and child health.

Purpose of the Study:

  • To evaluate the potential influence of SARS-CoV-2 infection in pregnant women on infant neurobehavioral development.
  • To assess specific domains of infant neurobehavioral development affected by maternal COVID-19.
  • To establish a baseline for future research on this topic.

Main Methods:

  • A case-control study was conducted with 9 pregnant women infected with SARS-CoV-2 and 9 matched controls.
  • Infant neurobehavioral development was assessed using the Ages and Stages Questionnaires Edition 3 (ASQ-3).
  • Maternal age, parity, and chronic disease status were used for matching.

Main Results:

  • Neonates born to mothers with SARS-CoV-2 infection showed lower ASQ-3 scores in communication, gross motor, fine motor, problem-solving, and personal-social domains.
  • A statistically significant difference was observed in the fine motor domain (P = 0.031).
  • All newborn throat swabs were negative for SARS-CoV-2.

Conclusions:

  • SARS-CoV-2 infection during pregnancy may adversely affect infant neurobehavioral development.
  • Fine motor skills appear to be particularly vulnerable to maternal COVID-19.
  • Larger sample sizes are required to validate these preliminary findings and understand long-term implications.
