ABSTRACT

Background: Wheat flour in Chile is fortified with folie acid and pregnant women are also supplemented with the vitamin, but the population level of knowledge or awareness about this vitamin and its use by pregnant women is unknown. Aim: To assess the level of knowledge that postpartum women from Santiago de Chile have about folie acid. Material and methods: A questionnaire about folie acid and its efects on the prevention of neural tube defects was developed adapting questionnaires designed abroad. It was applied by medical students to puerperal women, hospitalized in public hospitals. Results: The questionnaire was applied to 342 women aged 26 ± 7 years. Sixty one percent were housewives and 55 percent completed high school education. Forty seven percent of these women had heard about folie acid, 9.6 percent knew that it was able to prevent congenital defects and only one received an adequate supplementation during pregnancy. Women aged 25 to 34 years and those with an adequate medical care during pregnancy had a significantly better knowledge about folie acid and its role in the prevention of congenital anormalies. The more commom means to receive information about folie acid were midwifes (34 percent), mass media (28 percent) and doctors (20 percent). Two hundred eleven women (62 percent) agreed to take folie acid in a future gestation and 58 percent preferred to do so using fortified foods. Conclusions: Post partum women from Santiago have a poor knowledge about the relevance of folie acid supplementation.
