Research Reports:

  • Impact of Folic Acid Fortification of the US Food Supply on the Occurrence of Neural Tube Defects.
    Margaret A. Honein, PhD,MPH; Leonard J. Paulozzi, MD; T. J. Mathews, MS; J. David Erickson, DDS,PhD; Lee-Yang C. Wong, MS. JAMA. 2001;285:2981-2986.

    The article addresses the reduction in babies born with NTDs after folic acid was added to the US food supply. However, other factors may have contributed to this decline.  This site has many links for folic acid and related neural tube birth defects.


  • Trends in Folic Acid Supplement Intake Among Women of Reproductive Age - California, 2002—2006.
    CDC. MMWR. October 26, 2007 / 56(42);1106-1109.

    A California study found that the percent of Latinas taking a multivitamin decreased from 2002-2006.  This may be because Latinas receive less health counseling, have lower education levels and delay prenatal care. Cultural differences also might contribute to fewer Latinas consuming folic acid.

  • Folate Status in Women of Childbearing Age, by Race/Ethnicity - United States, 1999--2000, 2001--2002, and 2003—2004.
    CDC. MMWR. January 5, 2007 / 55(51);1377-1380.

    A study from 1999 through 2004 addresses the possible reasons for the decline of levels of folic acid in the blood. An increased popularity of low-carbohydrate (“low-carb”) diets might be a reason because women who eat fewer carbohydrates (“carbs”) might also eat less folic acid. Another reason may be because more women are becoming obese and  some doctors think overweight women need more folic acid to prevent neural tube defects.
