Effects of moderate alcohol consumption and smoking on fetal outcome
Previous studies of the effects of moderate drinking on the outcome of pregnancy are assessed. The results of a prospective study of the association between alcohol consumption in pregnancy and birthweight, length of baby, head circumference and premature delivery are described. Consumption of more than 10 g alcohol per day in very early pregnancy or even before conception approximately doubled the risk that the infant would have a low birthweight. Cigarette smoking was also a risk factor for low birthweight. It may therefore be beneficial for women to reduce their alcohol consumption to one drink a day or less from before conception and give up smoking as well.
