Effect of chorioamnionitis on postnatal growth in very preterm infants: a population-based study in Japan.

ABSTRACT:

Purpose

There is growing evidence that preterm infants born to mothers with chorioamnionitis (CAM) have increased risk of various neonatal morbidities and long-term neurological disorders; however, the effect of CAM on postnatal growth remains insufficiently investigated. This study evaluated the effect of histological CAM on postnatal growth trajectories in very preterm infants using a nationwide neonatal database in Japan.

Method

A multicenter retrospective study was conducted using clinical data of 4220 preterm neonates who weighed ≤ 1500 g and were born at < 32 weeks of gestation between 2003-2017 (CAM group: n = 2110; non-CAM group: n = 2110). Z-scores for height and weight were evaluated at birth and 3 years of age. Univariable and multivariable analyses were conducted
