Abstract

Objective To characterize the association of histological chorioamnionitis (HCA) with neurodevelopmental outcomes in children born at

Study design This retrospective cohort study included infants born 2006-2012 in whom placental histopathology, neonatal outcomes, and Bayley-III assessment at age 2 years were available. We assessed the association of HCA exposure with cognitive, language, and motor delay with logistic regression models adjusted for gestational age, sex, small for gestational age and brain injury.

Results Of 1353 infants, 985 had histological and neonatal data available, and 708 infants had Bayley-III assessments. HCA-exposed infants were at higher risk of some neonatal adverse outcomes, and stage of HCA correlated with low Apgar score and early-onset sepsis. Exposure to HCA was not associated with neurodevelopmental outcomes in adjusted models including stage of HCA.

Conclusions Exposure to HCA, especially higher stage, was associated with neonatal morbidity but not with adverse neurodevelopmental outcomes at 2 years of age.
