IS A light tipple when you’re pregnant OK? Lots of expecting mums now say they avoid even light drinking, but the latest study indicates that this may be an unnecessary precaution.
Yvonne Kelly and colleagues from University College London analysed data collected from over 12,000 mothers and children in the UK since 2001. Children whose mothers had one or two alcoholic drinks per week during pregnancy had fewer behavioural and cognitive problems by age 3 than the children of women who abstained completely (International Journal of Epidemiology, DOI: 10.1093/ije/dyn230).

These people might be more likely interact with their child in a way that helps them do well in cognitive tests, which would affect the results, even though Kelly says she went to “enormous lengths” to remove the influence of social factors. Light drinking could also help women to relax, making the pregnancy less stressful.

While heavy drinking is known to cause fetal alcohol syndrome, the effects of a few drinks are harder to pin down (New Scientist, 29 June 2006, p 46). To be on the safe side, many countries now recommend abstaining.
Fred Bookstein, professor of statistics at the Universisty of Washington in Seattle says the research on light drinking has not arrived at a “stable conclusion”. “We have no evidence that it does anything and it probably makes women feel
