Alcohol abuse in pregnancy causes fetal alcohol spectrum disorders ranging from discreet developmental problems to fetal alcohol syndrome. That is why pregnant women and the women considering pregnancy should abstain from alcohol. Fetal alcohol spectrum disorders occur even after drinking at early stages of pregnancy when women are not aware of being pregnant. According to one study 75% Czech women drank alcohol before pregnancy and one third of them continued during first three months of pregnancy. According to new epidemiological data 83.4% of Czech women aged between 18 and 40 drank alcohol during the year preceeding the pregnancy. The prevention in this area in the Czech Republic is clearly not satisfactory, and it is complicated by the alcohol advertising targeted at women, low taxation of alcohol and other factors.
