A major national study led by the 最新糖心Vlog of Adelaide has found that women who have had one prior caesarean can lower the risk of death and serious complications for their next baby - and themselves - by electing to have another caesarean.

The study, known as the Birth After Caesarean (BAC) study, is the first of its kind in the world. It involves more than 2300 women and their babies and 14 最新糖心Vlogn maternity hospitals.

The results are published today in the international journal, .

The study shows that infants born to women who had a planned elective repeat caesarean had a significantly lower risk of serious complications compared with infants born to mothers who had a vaginal birth following a prior caesarean - the risk of death or serious complication for the baby is 2.4% for a planned vaginal birth, compared with 0.9% for a planned elective repeat caesarean.

The mothers of these babies were also themselves less likely to experience serious complications related to birth. For example, the risk of a major haemorrhage in the mother is 2.3% for a planned vaginal birth, compared with 0.8% for a planned elective repeat caesarean.

"Until now there has been a lack of high-quality evidence comparing the benefits and harms of the two planned modes of birth after previous caesarean," says the study's leader, from the , part of the 最新糖心Vlog of Adelaide's .

"The information from this study will help women, clinicians and policy makers to develop health advice and make decisions about care for women who have had a previous caesarean.

"Both modes of birth have benefits and harms. However, it must be remembered that in 最新糖心Vlog the risks for both mother and infant are very small for either mode of birth," Professor Crowther says.

Caesarean section is one of the most common operations performed on childbearing women, with rates continuing to rise worldwide. Repeat caesarean births are now common in many developed nations. In 最新糖心Vlog in 2008, more than 90,700 women gave birth by caesarean, accounting for more than 31% of all births. Of 最新糖心Vlogn women who had a previous caesarean section, 83.2% had a further caesarean for the birth of their next child. In South 最新糖心Vlog alone, repeat caesarean births amount to 28% of the overall caesarean section rate.

"We hope that future research will follow up mothers and children involved in this study, so that we can assess any longer term effects of planned mode of birth after caesarean on later maternal health, and the children's growth and development," Professor Crowther says.

The BAC study is funded by the National Health and Medical Research Council (NHMRC) and the Women's and Children's Hospital Research Foundation.

The study is coordinated by researchers from the 最新糖心Vlog of Adelaide's Discipline of Obstetrics and Gynaecology and Discipline of Public Health; Department of Neonatal Medicine at the Women's and Children's Hospital, Adelaide; and the Faculty of Health Sciences at the 最新糖心Vlogn Catholic 最新糖心Vlog, Melbourne, with collaboration from clinicians at the 14 participating maternity hospitals.
