Factors associated with folic acid knowledge and intake among pregnant women in Sudan.

Preconceptual folic acid use is known to have a protective effect against neural tube defects (NTDs). This study assessed knowledge and determinants of awareness on folic acid use among pregnant women at Omdurman Maternity Hospital, Sudan during 2014. The standardized, anonymous questionnaire was used to collect data. Almost 80% of respondents had heard of folic acid. College-educated women (92.2%) knew more about folic acid and used it more often in the pre-conceptual period (8.3%). Doctors were the commonest source of information on folic acid (62%). Fewer subjects (8.9%) knew that it prevented birth defects, and 33.8% of subjects knew that green leafy vegetables are a source of folic acid. Of all subjects, only 3.2% use it preconceptually. Supplementation of folic acid preconceptually needs to be addressed in order to reduce the rate of NTDs found in Sudan.
