Watson HJ, et al. - Researchers examined 46,373 adult women enrolled in the Norwegian Mother and Child Cohort Study (den norske Mor & barn-undersøkelsen [MoBa]) to determine if prenatal/perinatal complications are associated with lifetime eating disorders in women. This is the first known investigation examining prenatal and perinatal factors in binge-eating disorder and purging disorder (PD). A comparison was done between MoBa mothers with lifetime eating disorders and a referent group. They noted more frequent development of binge-eating disorder in later life among MoBa mothers who weighed more at birth or were born large-for-gestational-age. MoBa mothers who weighed less at birth developed anorexia nervosa more frequently. Outcomes thus suggest a possible relevance of fetal programming for the development of anorexia nervosa and binge-eating disorder.
