Chorioamnionitis and neurodevelopmental outcome in very preterm infants from 2007 to 2017-a population-based study.

Aim: The study compares neurodevelopmental outcome at 24 months corrected age of very preterm infants exposed to chorioamnionitis and controls. Peripartal parameters which may influence outcome are also investigated.

Methods: In this observational population-based study, very preterm infants born between 2007 and 2017 were eligible (n = 466) and included if a histological placental examination and a complete neurodevelopmental assessment (Bayley Scale of Infant Development II or III) (n = 168) were performed.
