Abstract

Objective: To examine associations between oxidative stress and fetal weight across pregnancy. Study design: Cohort study of pregnant participants from 2016-2021 in New York City with urinary lipid, protein, and DNA oxidative stress biomarkers (<18, 18–25, >25 weeks) and estimated fetal weight from ultrasound fetal biometry with the HadlockIII formula (20, 30, 36 weeks). Result: Among 1408 participants, oxidative stress biomarkers of lipid peroxidation and DNA damage were associated with smaller estimated fetal weight at 30 and 36 weeks (ranging from B = –3.9 grams/unit increase [95% CI: –6.9, –0.9; 8,15 − PGF2α] to –20.3 [95% CI: –27.9, –12.8; 8 − OHdG]), particularly among fetuses at the 25th percentile. Oxidative stress biomarkers of protein damage were associated with larger estimated fetal weight at 20 (3.4 [95% CI: 1.2, 5.7]) and 36 weeks (16.5 [95% CI: 5.2, 27.8]). Conclusion: These findings advance our understanding of different oxidative stress pathways and their potential role in fetal growth.
