Duration of breastfeeding was reported by the participants' mothers in 1997. We used generalized estimating equations to estimate the association of breastfeeding with purging, binge eating, engaging in bulimic behaviors, and having a diagnosed eating disorder.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared to girls who were breastfed for more than 9 months, those who were breastfed for less than 4 months did not have a significantly different prevalence of purging, binge eating, bulimic behaviors, and self\u2010reported history of diagnosed eating disorders. Adjusting for gestational age\/birthweight, age, age at menarche, maternal history of an eating disorder, and maternal body mass index, short duration of breastfeeding was not associated with any outcome among the girls [adjusted odds ratios (AOR) ranged from 0.8 to 1.1]. Among the boys, the results showed no significant associations between duration of breastfeeding and purging, binge eating, and self\u2010reported history of diagnosed eating disorder. However, there was a suggestion that boys who had been breastfed for less than 4 months were at a higher risk of engaging in bulimic behaviors [AOR: 1.5, 95% confidence interval (CI), 1.0\u20132.3].<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>No association was found between duration of breastfeeding and risk of developing bulimic behaviors or a diagnosed eating disorder among girls or boys with the one exception of longer duration of breastfeeding associated with fewer bulimic behaviors in boys. Although there are many benefits to breastfeeding, our data suggest that breastfeeding does not offer any protection against binge eating or purging, nor does it present harmful effects. \u00a9 2013 Wiley Periodicals, Inc.
