About

The study objective is to assess the knowledge and the follow-up of vitamin B9 supplementation recommendations for women in the periconceptional period to prevent neural tube closure defects. It will be conducted with health professionnals and women who have just given birth in Rennes CHU.

This study aimes to assess men's and women's knowledge of the need to take vitamin B9 supplementation in women in the periconceptional period and the reasons why this supplementation is carried out or not, in order to target our future prevention campaign.

This will allow comparing the results before and after the prevention campaign.

Full description

Neural tube closure defects are among the most common birth defects. They are also called Spina Bifida or spinal dysraphism. According to the latest epidemiological studies in Europe based on the EUROCAT register (1991-2011), the prevalence of neural tube closure defects (including spinal dysraphisms as well as anencephaly and encephalocele) at birth is estimated at 9.105/10000 births in Europe (95% CI 8.94 to 9.27) and 12.02/10000 births in France.

The effectiveness of vitamin B9 (or folic acid or folate) supplementation in the periconceptional period on reducing the prevalence of neural tube closure defects has been widely demonstrated.

In France, the HAS (public health agency) recommends taking vitamin B9 between 1 month before and 2 months after conception, at a dose of 0.4 mg per day (5 mg per day in case of risk factors) since 2009. However, the proportion of women taking folic acid during periconceptional period is estimated at 1%.

The spina bifida - dysraphisms centre of the University Hospital Center of Rennes wishes to implement a campaign to prevent neural tube closure defects by supplementing with vitamin B9 during periconceptional period.

This will allow comparing the results before and after the prevention campaign. Finally, such a study is an awareness-raising campaign by itself. The study objective is to assess the knowledge and the follow-up of vitamin B9 supplementation recommendations for women in the periconceptional period to prevent neural tube closure defects. It will be conducted with health professionnals and women who have just given birth in Rennes CHU.

A questionnaire will be administered to each study participant, among 2 distinct populations:

Paper questionnaire for women who have just given birth during their stay in the maternity ward at the University Hospital of Rennes. Electronic questionnaire (Sphinx Déclic) sent to all CHU mailbox users.
