Preconceptional Care• On average, those physicians who
provide any prenatal care see 20% (FPs: 21%) of all their prenatal patients for a preconceptional care visit prior to their pregnancy.

Patient-Initiated Inquiries
• Almost all respondents (80% of OB/GYNs and 92% of FPs) report that less than one-quarter of their patients bring up the issue of folic acid on their own.

Reasons Physicians Don’t Always Recommend Folic Acid or Multivitamins
• Both OB/GYNs and FPs cite lack of knowledge (~40%) and lack of time (30%) as the primary reasons that some physicians may not address folic acid with all women of childbearing age.
– Physicians note a need for more knowledge or information about folic acid, nutrition, and unintended pregnancy.
Preferred Information Sources Each physician identified up to two types of medical
information resources that would be effective at reaching him/her with information about folic acid.
Medical journals are the most popular information source, attracting the attention of two-thirds of the OB/GYNs and FPs.
Much smaller segments express a preference for obtaining information through medical associations or medical conferences (10%-12% each), the Internet (6%-7%), or any other modality.
Q. 22 “What sources of medical information would be most effectiveat reaching you with information about folic acid?”
Resources Needed for Patients Physicians were asked to identify up to two types of
resources he/she would like to have to promote folic acid intake among patients.
Tangible printed materials were the most popular request. 57% of OB/GYNs and 66% of FPs requested patient
brochures. Additional resources requested include posters and
charts, articles, Spanish and other non-English-language publications, and handouts or literature for patients.
Q. 23 “What resources would you like to have to promote preconceptional
folic acid intake in your female patients of reproductive age?”
Summary: Understanding of Folic Acid
While physicians universally understand the role of
folic acid in preventing some birth defects, only one-
half are aware of the RDA for a typical non-pregnant
woman of child-bearing age (that is, one with no other
conditions or risk factors that would warrant
additional folic acid).
Summary: Timing of Folic Acid
Although physicians understand the need for women to take folic acid prior to becoming pregnant, in practice they seldom take the initiative to recommend folic acid except
after conception.
Many are not aware of the high percentage of unintended pregnancies.
Only one-fifth initiate preconceptional care visits.
Summary: Prevention or Well-Woman Care
Folic acid supplementation (including multivitamins) is low among many competing
priorities for physicians during the provision of preventive or well-woman care.
Both lack of information and lack of time during a busy exam schedule are major factors that prevent
physicians from addressing folic acid with their patients.
Summary: Folic Acid After NTD Event
Opportunities are being missed to prevent recurrence of NTD-affected pregnancies due to
physicians’ lack of awareness of the recommended peri-conceptional dose, and their limited initiative in
promoting folic acid preconceptionally.
Summary: Information and Communications
Three-quarters of physicians recall seeing information on folic acid from a variety of sources; they prefer to
obtain information about folic acid through their professional journals.
Two-thirds of physicians prefer printed handouts to communicate with patients about folic acid.
