Frequency of weight\u2010related CB at pre\u2010 and 10\u00a0years post\u2010surgery was assessed and participants were classified as those who (1) never, (2) continued, (3) remitted, or (4) developed CB. Exploratory analyses investigated preoperative and postoperative factors associated with remission, continuation, or development of CB.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Pre\u2010operatively, 26.9% reported fasting, 17.6% diuretic misuse, 11.9% laxative misuse, and 8.3% self\u2010induced vomiting. At 10\u00a0years, 8.3% reported fasting, while fewer than 3% reported the other CB. In terms of classification, 55% had never engaged in weight\u2010related CB, 31.1% remitted, 9.8% continued, and 3.6% reported de novo CB. No significant differences in demographic or mental health factors were observed between these groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Maladaptive, weight\u2010related CB were relatively common prior to surgery but declined substantially after a decade.
