Best advice for a pregnant woman is not to drink alcohol at all. Second best advice is not to drink alcohol every day. This is especially important in the beginning and in the end of pregnancy. The limit in these periods is one drink per day. Beyond this limit the risk for low birth weight and preterm birth increases substantially. The higher the alcohol consumption, the higher the risk. This is the result of a Dutch population study in more than seven thousand women.
According to this study, the average weight of babies whose mothers have consumed one or more alcoholic drinks per day is 129 grams less, compared with a consumption of less than one drink per day in pregnancy. For low birth weight, the risk is nearly five-fold and for preterm birth more than double.
