Women were recruited between 6 and 12 weeks postpartum in Tianjin, China,between July 2015 and July 2016 Results A total of 1,921 women were recruited in the study. Approximately 93.1% of the studyparticipants used FA, while 14.4% of the women taking FA from three months prior to preconception tothree months post-conception. Women who took FA for three months prior to preconception throughat least three months into their pregnancy were more likely to be between 30 and 34 years old （OR =2.91, 95% CI： 1.15, 7.33）, employed （OR = 2.07, 95% CI： 1.17, 3.67）, primigravida （OR = 5.20, 95% CI：3.02, 8.96）, married to spouses with an intermediate education level （OR = 2.92, 95% CI： 1.45, 5.89）, andearn a high family income （OR = 3.19, 95% CI： 1.57, 6.49） Conclusion The prevalence of periconceptional FA intake was far below the requirements of theNational Health and Family Planning Commission of China; therefore, knowledge of FA supplementationshould be strengthened among women who are or planning to become pregnant.展开更多

Anencephaly and spina bifida are the two major subtypes. Fetuses with anencephaly are often stillborn or electively aborted due to prenatal diagnosis, or they die shortly after birth. Most infants with spina bifida are live-born and, with proper surgical treatment, can survive into adulthood. However, these children often have life-long physical disabilities. China has one of the highest prevalence of NTDs in the world. Inadequate dietary folate intake is believed to be the main cause of the cluster. Unlike many other countries that use staple fortification with folic acid as the public health strategy to prevent NTDs, the Chinese government provides all women who have a rural household registration and who plan to become pregnant with folic acid supplements, free of charge, through a nation-wide program started in 2009. Two to three years after the initiation of the program, the folic acid supplementation rate increased to 85% in the areas of the highest NTD prevalence. The mean plasma folate level of women during early and mid-pregnancy doubled the level before the program was introduced. However, most women began taking folic acid supplements when they knew that they were pregnant. This is too late for the protection of the embryonic neural tube. In a postprogram survey of the women who reported folic acid supplementation, less than a quarter of the women began taking supplements prior to pregnancy, indicating that the remaining three quarters of the fetuses remained unprotected during the time of neural tube formation. Therefore, staple food fortification with folic acid should be considered as a priority in the prevention of NTDs.展开更多

A sample of 300 married women in the childbearing age (19 - 45 years) in Hail in the period between October/2011 and January/2012 participated in a survey study regarding awareness and use of folic acid before and during pregnancy. Participant women were asked to respond to different questions related to age, level of education, occupation, monthly income, gravidity, and other information concerning folic acid awareness, specific knowledge, supplementation practices, and source of knowledge about the preconceptional intake of folic acid. While 91.0% of the subjects were aware of folic acid, 81.0% knew that folic acid could prevent neural tube defects and 84.0% of the subjects took folic acid prior or during a certain stage of pregnancy. Nonetheless, only 10.0% of the subjects who proclaimed that they know the proper timing for folic acid supplementation recognized that folic acid should be taken prior and during the first trimester of pregnancy. University education was the strongest predictor of folic acid knowledge and university educated subjects had significantly (P P展开更多
