Quit smoking in early pregnancy

30th March 2009

Researchers in New Zealand are finding that pregnant women who wish to protect the health of their babies should give up smoking by the 15th week of pregnancy.


The finding, the first to show that women who stop smoking in early pregnancy can reduce health risks to their babies, shows that women who keep smoking after 15 weeks give birth prematurely more frequently than women who do not, and that their babies tend to suffer from low birth weight.

Lesley McCowan of the University of Auckland, the study’s lead researcher, said that pregnant women who smoke should be encouraged and assisted to become smoke-free early in pregnancy.

She said that the study also found that stress levels between women who quit and women who did not were roughly the same.

Women who smoke while pregnant also increase their chances of miscarrying or having babies that are stillborn.

Researchers collected date from some 2,500 women, most of whom did not smoke, 10% of whom did, and 10% of whom had quit smoking.

The rates of spontaneous premature birth were the same between women who abstained completely and women who quit before reaching week 15 of pregnancy, with 4% of cases from both groups classified as spontaneous premature births.

In addition, there was no difference in the number of women whose babies were smaller than expected, with results 10% each way.

For people who smoked past the 15 week mark, the rate of premature babies climbed to 10% among women who smoked, and the rate of unusually light infants rose to 17%.

Women who did not quit smoking after 15 weeks were ultimately three times more likely to give birth prematurely and twice as likely to have smaller babies.

McCowan said that health professionals who care for pregnant women need to ask about their smoking habits, as well as advise them about the importance of stopping.

She said that, where possible, health professionals must get extra support to assist women to become smoke-free in early pregnancy.

However, Richard Frieder, an associate clinical professor at the University of California at Los Angeles, said that the difference in low birth weights and gestational ages at delivery has not yet been clearly linked to a health difference.

He said that people assume one exists, even if there is only about a half pound difference in birth weight, or six days of difference in gestational age.

He said babies living in 'smoking homes' have other dangers to face such as a much higher risk of asthma, pneumonia and SIDS.
