Evaluation of the prevalence of folic acid supplementation before conception and through the first 12 weeks of pregnancy in Polish women at high risk of fetal anomalies.

We found an unsatisfactory compliance with recommendations for the use of folic acid supplementation during periconceptional period among women at high risk of fetal defects and folate deficiency, that could have negative effects on the health of child and mother. The study results show the need to increase the awareness of FA supplementation during periconceptional period especially in women with high risk of fetal anomalies.
