摘要

目的:神经性贪食症(BN)患者在治疗期间经常体重增加,这可能对治疗依从性构成威胁。虽然体重抑制已被发现是BN患者体重增加的一个预测因素,但关于治疗期间体重变化的轨迹及其其他预测因素的研究很少。方法:目前的研究检查了2015年至2020年期间在Schoen Clinic Roseneck (Prien am Chiemsee, Germany)住院治疗的746名BN患者(95%为女性)的体重抑制以及入院时自我报告的暴饮暴食严重程度和排泻频率作为体重变化的预测因素。结果:身体质量指数(BMI)在治疗周内呈线性增加。较高的体重抑制预示着较大的体重增加,特别是那些入院时BMI相对较低的患者。更频繁的排便和不太严重的暴食预示着更大的体重增加,但高暴食严重程度和不频繁的排便相结合会减弱这种影响。结论:结果重复了那些体重抑制程度高的人在BN治疗期间体重增加的风险更高,但扩展了这些发现,因为这种影响还取决于当前的BMI,类似于神经性厌食症患者的研究结果。他们进一步证明,bn的核心特征——暴食和排便——也可以单独或相互作用地预测体重变化,因此,可以在心理教育和治疗计划中加以考虑。

Weight Suppression, Binge Eating, and Purging as Predictors of Weight Gain During Inpatient Treatment in Persons With Bulimia Nervosa

Weight Suppression, Binge Eating, and Purging as Predictors of Weight Gain During Inpatient Treatment in Persons With Bulimia Nervosa

Objective

Persons with bulimia nervosa (BN) often gain weight during treatment, which potentially poses a threat to treatment adherence. Although weight suppression has been found to be a predictor of weight gain in persons with BN, research about the trajectory of weight changes during treatment and other predictors thereof is scarce.

Method

The current study examined weight suppression as well as self-reported binge eating severity and purging frequency at admission as predictors of weight change in 746 persons with BN (95% female) who received inpatient treatment at the Schoen Clinic Roseneck (Prien am Chiemsee, Germany) between 2015 and 2020.

Results

Body mass index (BMI) increased linearly across treatment weeks. Higher weight suppression predicted larger weight gain, particularly in those with a relatively low BMI at admission. More frequent purging and less severe binge eating predicted larger weight gain but high binge eating severity in combination with infrequent purging attenuated this effect.

Conclusions

Results replicate that those with high weight suppression are at higher risk for gaining weight during BN treatment but extend these findings in that this effect additionally depends on current BMI, similar to findings reported in persons with anorexia nervosa. They further demonstrate that the core features of BN—binge eating and purging—also predict weight change both separately and interactively and may, therefore, be considered in psychoeducation and therapy planning.

期刊介绍: European Eating Disorders Review publishes authoritative and accessible articles, from all over the world, which review or report original research that has implications for the treatment and care of people with eating disorders, and articles which report innovations and experience in the clinical management of eating disorders. The journal focuses on implications for best practice in diagnosis and treatment. The journal also provides a forum for discussion of the causes and prevention of eating disorders, and related health policy. The aims of the journal are to offer a channel of communication between researchers, practitioners, administrators and policymakers who need to report and understand developments in the field of eating disorders.
