Alcohol consumption during pregnancy is a significant public health problem and is an established cause of serious birth defects and developmental delay collectively described as fetal alcohol syndrome (FAS). FAS is caused by congenital alcohol-induced damages and is a cause of mental retardation. It is characterised by facial abnormalities and growth deficiency. Infants affected by the syndrome show intellectual impairment, and difficulties in learning, memory, problem-solving, and attention as well as experiencing additional problems with mental health and social interactions. However, an absence of the characteristic facial defects and growth deficiency may result in a failure to identify children with prenatal alcohol exposure, which can further present as alcohol-related neurodevelopment disorder (ARND) or alcohol-related birth defects (ARBD). Estimates of prevalence of FAS in U.S.A. range between 0.3 to 2.2 per 1,000 live births, but much higher rates occurring in some communities. Harmonisation of the methodology used for epidemiological studies, with research activities that establishes real baseline prevalence of FAS and identification of women who are at highest risk of bearing a FAS-affected child, are an essential prerequisite to prevention. In addition, it is essential to assess different FAS preventive approaches through carefully controlled studies. Universal, selected, and indicated preventive strategies have been identified, targeting different kind of populations. Since FAS and other adverse effects of drinking during pregnancy are theoretically completely preventable, it is vital to make more efforts to improve the application of the most appropriate interventions. Although in Italy alcohol consumption has constantly increased, mainly amongst the young (including women of childbearing age), knowledge on FAS and alcohol-related effects is completely lacking. Because of the high cost for care of individuals with this syndrome, it is essential to apply appropriate interventions to prevent this problem.
