目的：比较涉及暴饮暴食的进食障碍成年人的饮食限制行为，包括神经性厌食症-暴饮暴食/清除亚型（AN-BE/P），神经性贪食症（BN）和暴饮暴食症（BED），并检查饮食限制行为是否影响诊断中的暴饮暴食频率。方法：参与者包括845名寻求治疗的成年人（M = 30.42 +/- 10.76岁），他们符合DSM-5 AN-BE/P（7.3%; n = 62），BN（59.7%; n = 504）和BED（33.0%; n = 279）的标准。所有参与者自我报告他们过去和目前的饮食失调症状的饮食失调Questionnaire.Results：成人AN-BE/P和BN报告显着更多的饮食限制行为（e。G.与卧床的成年人相比，每天少吃一餐，禁食的频率更高，摄入少量和低热量的食物。患有AN-BE/P和BN的成年人报告通过每天少吃一餐来限制食物摄入，他们的暴饮暴食事件更频繁。然而，成年人与BN谁报告限制食物摄入量，通过吃小餐和低热量的膳食有较少的暴饮暴食epissions.Discussion：这项研究提供了混合支持的约束模型，并不是所有的饮食限制行为与更高水平的暴饮暴食。这可能是因为BN的成年人报告吃少量和低热量食物的频率较高，一般来说对他们的饮食有更多的控制，因此也有较低的暴饮暴食频率。临床医生应该在治疗开始时评估饮食限制行为，然后再假设所有形式的严格节食和体重控制行为都同样会影响暴饮暴食。(C)2015爱思唯尔有限公司版权所有。
Objective: To compare dietary restriction behaviors among adults with eating disorders involving binge eating, including anorexia nervosa-binge/purge subtype (AN-BE/P), bulimia nervosa (BN), and binge eating disorder (BED), and to examine whether dietary restriction behaviors impact binge eating frequency across diagnoses.Method: Participants included 845 treatment seeking adults (M = 30.42 +/- 10.76 years) who met criteria for DSM-5 AN-BE/P (7.3%; n = 62), BN (59.7%; n = 504), and BED (33.0%; n = 279). All participants self-reported their past and current eating disorder symptoms on the Eating Disorder Questionnaire.Results: Adults with AN-BE/P and BN reported significantly more dietary restriction behaviors (e. g. eating fewer meals per day, higher frequency of fasting, consuming small and low calorie meals) in comparison to adults with BED. Adults with AN-BE/P and BN who reported restricting food intake via eating fewer meals per day had more frequent binge eating episodes. However, adults with BN who reported restricting food intake via eating small meals and low calorie meals had less frequent binge eating episodes.Discussion: This study provides mixed support for the restraint model by suggesting that not all dietary restriction behaviors are associated with higher levels of binge eating. It may be that adults with BN who report a higher frequency of eating small and low calorie meals display more control over their eating in general, and therefore also have lower frequency of binge eating. Clinicians should assess for dietary restriction behaviors at the start of treatment prior to assuming that all forms of strict dieting and weight control behaviors similarly impact binge eating.
