ABSTRACT:

Objective

To produce current data on survival of preterm infants.

Design

Retrospective population based study.

Setting

Trent health region.

Subjects

All European and Asian live births, stillbirths, and late fetal losses from 22 to 32 weeks' gestation, excluding those with major congenital malformations, in women resident in the Trent health region between 1 January 1994 and 31 December 1997.

Main outcome measures

Birth weight and gestational age specific survival for both European and Asian infants (a) known to be alive at the onset of labour, and (b) admitted for neonatal care.
