Пьянство
Binge drinking is a more important factor rather than average alcohol intake, with regard to the severity of alcohol induced damage to the fetus. Alcohol has definite long-term adverse effects on the fetus, in particular impaired attentional skills and may lead to psychiatric disorders when the child grows up. In a 2005 study in the US, approximately one in five non-pregnant women binge-drank and one in 25 pregnant women binge-drank. Binge drinking during pregnancy is associated with fetal alcohol syndrome, alcohol-related birth defects as well as alcohol-related neurodevelopmental disorders. The affected children after birth can suffer mental retardation and problems with learning, memory, attention, problem solving and problems with mental health and social interactions. Deformities in facial features, skeletal and body organs as well as a smaller head circumference are also sometimes present in these children. Studies in sheep indicate that fetal neurotoxicity induced by alcohol may be due to acidaemia and hypercapnia. Binge drinking three or more times during pregnancy has been associated with an increased risk of stillbirth.
