Drinking During Pregnancy Increases Risk of Premature Birth

ScienceDaily (Apr. 11, 2011) — Drinking alcohol during pregnancy is associated with an increased risk of miscarriage, premature birth, and low birth weight. But there are conflicting reports about how much alcohol, if any, it is safe for a pregnant woman to drink. New research published in Biomed Central's open access journal BMC Pregnancy and Childbirth looked at the amounts of alcohol women drank during their early pregnancy and showed the effect this had on their babies.

While about a fifth of these women said that they never drank, 71% claimed to be occasional drinkers (0-5 units a week). Within this low-alcohol group there was one case of fetal alcohol syndrome, so it is likely that some of the women were underestimating (or under reporting) the amount they drank.

The moderate and heavy drinkers were often first time mums (not surprisingly, unplanned pregnancy was associated with heavy drinking). Heavy drinking was also related to very premature birth, and hence all the problems premature babies have including the increased risk of disease as an adult. However, there was no difference in occurrence of congenital or other birth defects regardless of the amount of alcohol drunk.

Prof Murphy said, "This study emphasizes the need for improved detection of alcohol misuse in pregnancy and for early intervention in order to minimize the risks to the developing fetus. We would recommend that further research is required before even low amounts of alcohol can be considered safe."
