Pre-pregnancy prevalence estimates in the validation sample were: anorexia nervosa (AN; 0.1%), bulimia nervosa (BN; 1.0%), binge eating disorder (BED; 3.3%) and eating disorder not otherwise specified-purging disorder (EDNOS-P; 0.1%). In early pregnancy, estimates were: BN (0.2%), BED (4.8%) and EDNOS-P (&lt;0.01%). Incident BN and EDNOS-P during pregnancy were rare. The highest rates were for full or partial remission for BN and EDNOS-P and continuation for BED.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291712002516_sec_a4\" sec-type=\"conclusion\"><jats:title>Conclusions<\/jats:title><jats:p>We validated previously estimated rates of remission, continuation and incidence of eating disorders during pregnancy. Eating disorders, especially BED, during pregnancy were relatively common, occurring in nearly one in every 20 women. Pregnancy was a window of remission from BN but a window of vulnerability for BED. Training to detect eating disorders by obstetricians\/gynecologists and interventions to enhance pregnancy and neonatal outcomes warrant attention.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0033291712002516","type":"journal-article","created":{"date-parts":[[2012,11,20]],"date-time":"2012-11-20T13:52:32Z","timestamp":1353419552000},"page":"1723-1734","source":"Crossref","is-referenced-by-count":59,"title":["Remission, continuation and incidence of eating disorders during early pregnancy: a validation study in a population-based birth cohort"],"prefix":"10.1017","volume":"43","author":[{"given":"H.
