Maternal obesity and birth defects

Mothers of babies born with some structural birth defectsincluding missing limbs, malformed hearts and underdeveloped spinal cordsappear more likely to be obese prior to becoming pregnant than mothers whose children are born without such defects, according to a report in the August issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
