Folic Acid: Are they getting enough? (infographic)
What we know
Age, education, geographic location and income affect what women know about the importance of folic acid. According to the Canadian Community Health Survey (2015) women aged 15–45 years who had given birth in the past 5 years:
- Before their pregnancy, 71% of women knew that taking folic acid before conception can lower the risk of neural tube defects (NTD).
- 60% of women reported taking folic acid in the three months before conception. 98% of these women took it daily or almost daily.
Recommended Dietary Allowance
Women of reproductive age: 400 mcg dietary folate equivalents per day
Pregnant women: 600 mcg dietary folate equivalents per day
What you need to know
To reduce the risk of fetal neural tube defects, women of reproductive age (12-45 years of age) who could become pregnant need to be advised on the benefits of folic acid in a multivitamin supplement. Promote the following, regardless of whether the client is planning a pregnancy or not:
- A diet high in folate should be encouraged, but as dietary intake is not enough to reach red blood cell folate levels associated with maximal protection against neural tube defects, a daily multivitamin containing 0.4 mg of folic acid is needed for low risk women who are of reproductive age and could become pregnant.
- Higher intake of folic acid for women with these risk factors:
- Previous pregnancy affected with NTD
- Personal or male partner family history of NTD
- Personal or family history of other folic acid related congenital anomalies
- Pre-pregnancy diabetes (type 1 or 2)
- Kidney dialysis
- GI malabsorption condition such as inflammatory bowel disease, celiac disease and gastric bypass surgery
- Antiepileptic or other folate inhibiting medications
- Advanced liver disease
- Alcohol overuse
