Background: A considerable local variability in the rate of bronchopulmonary dysplasia (BPD) has been recorded previously.

Objectives: The objectives of the present study were to describe regional differences in the rate of BPD in very preterm neonates from a European population-based cohort and to further delineate risk factors.

Methods: 4,185 survivors to 36 weeks' postmenstrual age of 4,984 live-born infants born at 24+0-31+6 weeks' gestation in 2003 (the MOSAIC cohort) in 10 European regions were enrolled using predefined structured questionnaires.
