Abstract
The preventive efficacy of the periconceptional use of folic acid is well established for neural
tube defects. Similar but lower protective effects have been suggested for other congenital
malformations such as orofacial clefts and some heart defects. This support the recommendation
that all women planning or at risk of pregnancy take a daily multivitamin supplement
containing folic acid, beginning one month before conception and continuing through the first
trimester for prevention of neural tube defects and other congenital malformations. Despite
this consistent evidence, in Italy no folate strategy of supplementation before conception or
food fortification has been developed. Recently an intervention project started also in Italy, in
order to evaluate the efficacy of a national preventive campaign on parents’ behaviour.
