Abstract

Background: To examine whether financial stress during pregnancy mediates the association between maternal exposure to adverse childhood experiences (ACEs) and three birth outcomes (i.e., gestational age, birth weight, and admission to the neonatal intensive care unit [NICU]). Methods: Data were obtained from a prospective cohort study of pregnant women and their infants in Florida and North Carolina. Mothers (n = 531; Mage at delivery = 29.8 years; 38% Black; 22% Hispanic) self-reported their exposure to childhood adversity and financial stress during pregnancy. Data on infant gestational age at birth, birth weight, and admission to the NICU were obtained from medical records within 7 days of delivery. Mediation analysis was used to test study hypotheses, adjusting for study cohort, maternal race, ethnicity, body mass index, and tobacco use during pregnancy. Results: There was evidence of an indirect association between maternal exposure to childhood adversity and infant gestational age at birth (b = -0.03, 95% CI = -0.06 – -0.01) and infant birth weight (b = -8.85, 95% CI = -18.60 – -1.28) such that higher maternal ACE score was associated with earlier gestational age and lower infant birth weight through increases in financial distress during pregnancy. There was no evidence of an indirect association between maternal exposure to childhood adversity and infant NICU admission (b = 0.01, 95% CI = -0.02–0.08). Conclusions: Findings demonstrate one pathway linking maternal childhood adversity to a potentially preterm birth or shorter gestational age, in addition to low birth weight at delivery, and present an opportunity for targeted intervention to support expecting mothers who face financial stress.
