BACKGROUND: Prenatal psychological stress during pregnancy has been associated with adverse reproductive outcomes. A growing animal literature supports an association between psychological stress and oxidative stress. We assessed this relationship in pregnant women, hypothesising that psychological stress is associated with higher concentrations of oxidative stress biomarkers during pregnancy. METHODS: concentrations after adjusting for covariates. RESULTS: in unadjusted analyses. Associations were attenuated, but remained suggestive, after covariate adjustment. CONCLUSIONS: levels are associated with adverse birth outcomes, oxidative stress could be a mediator in these relationships.
