The results are reported from the first of four phases of a prospective study on the association between alcohol consumption during pregnancy and fetal harm. These data revealed a generally low level of alcohol consumption amongst the 1,008 respondents. Self-reported alcohol consumption was slightly, but significantly, positively correlated with previous obstetric problems. Evidence from other studies indicates that between 1.8 per cent and 4.8 per cent of the study group may run an enhanced risk of producing damaged babies.
