Neural tube defects (NTDs) are serious birth defects that affect an estimated 4000 pregnancies each year in the United States. However, women can substantially decrease the risk for this birth defect by consuming 400 micrograms (0.4 mg) of folic acid per day before conception and during early pregnancy. In September 1992, the Public Health Service (PHS) recommended that all women of childbearing age who are capable of becoming pregnant consume 400 micrograms of folic acid daily. To characterize knowledge about the benefits of folic acid and use of multivitamins containing folic acid among Georgia women, the Division of Public Health, Georgia Department of Human Resources (GDHR), analyzed data from the 1995 Georgia Women's Health Survey (GWHS)--a comprehensive study of women's health that included questions about folic acid. This report summarizes the survey findings regarding knowledge and use of folic acid, which indicate that only 20% of Georgia women aged 15-44 years consumed a multivitamin containing > or = 400 micrograms of folic acid per day, and 71% did not know that folic acid can prevent some birth defects.
神经管缺陷（NTDs）是严重的出生缺陷，在美国每年估计影响4000例妊娠。然而，女性在受孕前和怀孕早期每天摄入400微克（0.4毫克）叶酸，可大幅降低这种出生缺陷的风险。1992年9月，公共卫生服务部（PHS）建议所有有怀孕能力的育龄妇女每天摄入400微克叶酸。为了了解佐治亚州女性对叶酸益处的认识以及含叶酸多种维生素的使用情况，佐治亚州人力资源部公共卫生部（GDHR）分析了1995年佐治亚州女性健康调查（GWHS）的数据——这是一项关于女性健康的综合研究，其中包括有关叶酸的问题。本报告总结了关于叶酸知识和使用情况的调查结果，结果表明，佐治亚州15至44岁的女性中，只有20%的人每天服用含≥400微克叶酸的多种维生素，71%的人不知道叶酸可以预防某些出生缺陷。
