Rates of fetal growth restriction and small for gestational age neonates by COVID-19 epochs: Did the pandemic affect fetal biometry measurements?

SSSharon K. StortzJCJennifer CulhaneLLLisbet S. Lundsberg

Key Points

  • The research investigates the impact of COVID-19 on fetal growth metrics, specifically FGR and SGA rates.
  • Comparison of fetal biometry measurements pre-COVID and during acute-COVID.
  • Analysis of rates for fetal growth restriction (FGR) and small for gestational age (SGA) neonates.
  • Evaluation of ultrasound limitations in diagnosing FGR accurately.
  • Increased diagnosis of fetal growth restriction (FGR) during acute-COVID epoch.
  • Decreased rates of small for gestational age (SGA) neonates at birth during the same period.
  • Findings suggest potential biases in ultrasound diagnostics affecting fetal assessment.

Abstract

During the acute-COVID epoch, FGR diagnosis increased compared to pre-COVID while SGA at birth decreased. This highlights the limitation of prenatal ultrasound for precisely identifying fetuses at the highest risk of FGR, which may be due to confirmation bias or broad diagnostic criteria for FGR.
