(1178) Resolved fetal growth restriction is not risk-free: an analysis of maternal factors and neonatal outcomes

Thursday, February 12, 2026
3:30 PM - 5:00 PM  
Objective:
To identify maternal factors linked to fetal growth restriction (FGR) resolution and compare neonatal outcomes between resolved and persistent FGR at delivery

Study Design:
We performed a retrospective cohort study of FGR pregnancies delivered at Cleveland Clinic from January 1, 2010 to July 31, 2022 (IRB# 21-1064). Using EPIC and REDCap, we included cases with ultrasound-estimated fetal weight (EFW) or abdominal circumference (AC) < 10th percentile. We defined persistent FGR as EFW/AC remaining < 10th percentile throughout gestation. Resolved FGR had final EFW/AC ≥10th percentile. We excluded pregnancies <24 weeks, multifetal gestations, fetal anomalies, or genetic disorders. We analyzed maternal contributors to resolution using logistic regression and point-biserial correlation. Neonatal outcomes were compared with t-tests and chi-square. Delta heatmaps identified associations across variables.

Results:
Among 763 FGR pregnancies, 254 remained persistent and 145 resolved. Higher maternal BMI at delivery and increasing parity were significantly associated with FGR resolution. Gestational diabetes and hypertensive disorders showed no such association (Figure 1). Cesarean delivery for non-reassuring fetal status occurred in 11.8% of persistent vs. 9% of resolved cases (χ²=0.39, p=0.53). Persistent FGR neonates trended toward lower 10-minute Apgar scores and longer NICU stays (25 vs. 18 days, p=0.086). Intubation and CPAP durations did not differ significantly between groups. 

Conclusion:
In this large cohort, higher maternal BMI and parity predicted FGR resolution. However, resolved FGR neonates experienced similar risks to those with persistent FGR, including longer NICU stays and comparable respiratory support needs. Resolution by ultrasound alone may not reflect full physiologic recovery. These findings underscore the importance of continued antenatal surveillance and tailored perinatal management, even in pregnancies where FGR appears to resolve.
