Many Australian women who smoke don't quit during pregnancy ... and when they cut back it's only by a couple of cigarettes a day.
... 37 per cent of the women were smokers before they fell pregnant, and this declined to about 25 per cent once they became aware of their condition.
Those who continued to smoke ... reduced their intake from an average of 16 cigarettes a day to 13.
Smoking during pregnancy increases the risk of miscarriage, and a host of health problems for the baby linked to an increased risk of premature birth and low birth weight.
... The study also found that more than 40 per cent of women in the study were overweight or obese, they consumed half the recommended serving of fruit and a third of the recommended serving of vegetables.
