But isn't the whole point that the true effects are not known?
No woman in their right mind would volunteer to be the "80 units per week" subject or even the "30 units per week" subject for a randomised controlled trial during her pregnancy.
In fact, it is unlikely that most women would tell their midwife exactly how much they drink. It is well known in health circles that if a patient tells you they smoke 10 cigarettes a day, they are likely to be smoking at least 15.
So, all the journals can report is speculative information, based on what they have been told by pregnant women as to how much alcohol is consumed. Then, people use this lack of information to justify continuing with something that has been shown to be a risk.
FAS has been shown to be 0.2-2 in 1000 in America. Spina Bifida is about 0.7 in 1000 in America - who's going to vote that you shouldn't bother taking Folic Acid because research only shows about a 70% decrease in incidence with FA? No, you take it because there is a chance that it will have an effect on the outcome.
I am that people can have such a cynical attitude to something so serious. Yes, of course the government are just joining with the masses to undermine the free will of women everywhere.
Come on, this isn't China where you get told how many children you can have. Britain is one of the most privileged countries in the world. Some women, even in America, for example, don't get any prenatal advice, because they can't pay for it.
How totally irresponsible for people to ignore completely the advice given to them. I am not talking about the odd glass of vino. If you can accept the (probably very small) risk then go for it.
What is known is that like so many other things, the risks for FAS can be disproportionate. The alcoholic down the road could have a string of healthy children, whilst the woman across the street who 'only' drank moderately could have a child with FAS.
Anyway, doubt my view will be popular. I just think that we need to remember that there are so many things you can't control in a baby's development. This is one thing you can.
