| pubmed-article:15648596 | pubmed:abstractText | Higher pre-pregnancy body mass index (BMI) is associated with increased risk of neural tube defects (NTDs) and possibly other negative birth outcomes in the offspring. The mechanism for this association remains unknown. Lower maternal folate level has been implicated in the etiology of NTDs in general. The association of BMI with folate level, however, has not been investigated. | lld:pubmed |
