A linked population data study involving population-based surveillance systems undertaken for the years 2000-2011 in New South Wales, Australia, has found that born before arrival (BBA) occurs more frequently in multiparous women of lower socioeconomic status.
The participants included all women who underwent BBA compared with women who birthed in hospital/birth centre settings. The study found that:
- During the time period there were 1,097,653 births and a BBA rate of 4.6 per 1,000 births.
- The BBA rate changed from 4.2 to 4.8 per 1,000 births over time.
- Neonates BBA were more likely to be premature, of lower birth weight and/or be admitted to a special care nursery or neonatal intensive care unit.
- The perinatal mortality rate was higher in the BBA cohort (34.6 compared with 9.3 per 1,000 births).
- Women in the BBA cohort were more likely to be in the lowest socioeconomic decile, multiparous, have higher rates of smoking and more likely to suffer a postpartum haemorrhage requiring transfusion than the non-BBA cohort.
- The most commonly occurring complications for neonates were suspected infection, hypothermia, congenital abnormality and neonatal withdrawal symptoms.
- BBA more commonly occurred in geographical areas where the distance to a maternity unit is >2 hours’ drive and in coastal regions where there is also a high rate of homebirth.
