1 in 3 women drink alcohol while pregnant: study

A study has found one third of Australian women have admitted to drinking alcohol when pregnant - and most would do it again.

The study by Elizabeth Peadon from the Westmead Children's Hospital surveyed 1,100 women aged between 18 and 40 years old.

Of those, 93 per cent said they knew alcohol could affect an unborn child.

Dr Peadon says the findings will be used to develop public health campaigns to inform pregnant women about the dangers of drinking.

The results have been presented at the Royal Australian College of Physicians conference today in Adelaide.
