title: Alcohol and abnormal outcomes of pregnancy.
abstract: Heavy alcohol consumption by the mother during pregnancy has long been suspected of being a risk factor for abnormalities in the fetus or infant. Only during the last decade have these assumptions been supported by scientific studies. A clustering of fetal defects observed in some cases has been labelled the fetal alcohol syndrome. The syndrome involves prenatal and postnatal growth retardation, central nervous system involvement and craniofacial abnormalities, some of which are characteristic of the syndrome. Fetal alcohol syndrome is relatively rare, affecting from 1 in 300 to 1 in 2000 infants; approximately 450 cases have been reported since the syndrome was identified. Despite this rarity, however, heavy alcohol consumption is an important risk factor during pregnancy. A review of the current literature indicates that in animals alcohol in high doses is embryotoxic and teratogenic, the heavy drinking is not uncommon before and during pregnancy and that the fetal alcohol syndrome and other effects on the fetus associated with alcohol abuse appear with significant frequency among mothers who drink heavily. Heavy alcohol consumption is a perinatal risk factor that not only can be detected by the physician, but also can be reduced in concerned, cooperative patients. Thus, awareness of this problem gives health care personnel an opportunity to help in the prevention of abnormal outcomes of pregnancy.
