Introduction: Folic acid Intakes before and during pregnancy can prevent fetal malformations. However, nowadays, intake of folate by pregnant women is very limited. Research objectives: This descriptive predictive study aimed to determine factors influencing folic acid intakes among pregnant women. Research methodology: A convenience sampling technique was used to recruit 130 pregnant women who visited an antenatal care clinic at Queen Savang Vadhana Memorial hospital. Research instruments included a demographic sheet, and a set of questionnaires, including knowledge about folic acid questionnaire, received information about folic acid questionnaire, perceived barriers to folic acid intake questionnaire, attitude towards folic acid intake questionnaire, folic acid intake before and during pregnancy questionnaire. The reliability of the questionnaires resulted in 0.79, 0.80, 0.78, 0.82, and 0.89, respectively. The study was conducted from June to August 2019. Data were analyzed using frequency, percentage, mean, standard deviation, and logistic regression analysis. Results: Results revealed that only 7.70% of pregnant women took folic acid three months before conception and first trimester of pregnancy. Factors influencing folic acid intakes among pregnant women were knowledge about folic (AOR = 17.46, 95% CI= 1.40-217.63), received information about folic acid (AOR = 208.07, 95% CI = 3.97-10903.52), and perceived barriers to folic acid intake (AOR = .79, 95% CI = .62-1.00). Factor not influencing folic acid intakes among pregnant women was attitude towards folic acid intake (AOR= .72, 95% CI= .46-1.14). Conclusion: Pregnant women rarely take folic acid before and during pregnancy. Such issue is very important for their health. Therefore, healthcare providers should be aware of this issue to prevent fetal malformations. Implications: These findings could be used to inform healthcare providers to develop effective campaign on knowledge about folic for women. Also, activities to promote folic intake before pregnancy among women of reproductive age should be implemented.
