Demographic factors determining folic acid supplementation in pregnant and childbearing age women

Objectives: Adequate folate intake constitutes a significant problem in the periconceptional period and early pregnancy but can be achieved by folic acid (FA) supplementation. Low intake of folate may cause numerous negative effects on the pregnancy outcome, including recurrent miscarriage, preeclampsia, fetal hypotrophy, premature delivery, premature placental abruption, and intrauterine fetal death. The aim of the study was to evaluate factors determining FA supplementation in the population of Polish women before and during pregnancy. Material and methods: The study group consisted of 257 women hospitalized postpartum at the Division of Perinatology and Women’s Diseases, Poznan University of Medical Sciences, Poland. We evaluated folic acid intake considering selected demographic data. A structured questionnaire was used to evaluate folic acid intake before and during pregnancy of the investigated women. Results: The vast majority of the investigated women (89.1%) took FA during pregnancy. During the pre-pregnancy period, a statistically significantly higher supplementation of folic acid was observed among women with the monthly income level of > 5000 PLN (p = 0.03), and among women who planned their pregnancy as compared to women who did not plan their pregnancy (p < 0.001). During pregnancy, these differences disappeared. A statistically significantly higher number of secundi- and multiparas did not take FA during pregnancy as compared to primiparas (p = 0.008). No correlation between cigarette smoking and FA intake was observed. Conclusions: Our analysis showed that FA intake increased (by 36.2%) during pregnancy as compared to the pre-pregnancy period, and depended on income, parity, and pregnancy planning
