摘要

目的:负面情绪下的情绪化进食可能是饮食失调行为(即暴饮暴食和食物限制)的基础。相比之下,积极情绪似乎能促进更健康的饮食行为。然而,对于暴饮暴食症(BED)、神经性贪食症(BN)、暴食型神经性厌食症(AN-BP)和限制性神经性厌食症(AN-R)患者的情绪与进食之间的联系,目前还缺乏自然研究:方法:无进食障碍者(对比组,CG,n = 85)和 BED(n = 41)、BN(n = 50)、AN-BP(n = 26)和 AN-R (n = 29)患者参加了一项生态瞬间评估研究。在八天时间里,每天发出六次通知,提示对瞬间的食物渴望和情绪状态进行评分,这些情绪状态在价位和唤醒程度上各不相同:结果:研究结果表明,每个组都有特定的情绪-食物渴望模式。与CG相比,BN患者会同时出现亢奋的负面情绪和更高的食物渴望。在厌食症-恶心-呕吐患者中(在厌食症-呕吐患者中也有趋势),唤起的负面情绪较少,渴求感较低。在 AN 患者中,积极情绪和较高渴求同时出现,而在 BED 患者中,唤起较少的积极情绪和较低的渴求同时出现:结论:所发现的情绪-渴求关联可能是特定群体(功能障碍)进食行为的基础,即BN和AN患者在负面情绪时会出现暴饮暴食和食物限制,而BED和AN患者在正面情绪时会出现正常化的食欲反应。治疗工作可针对 BN 患者的唤起性消极情绪和 AN 患者的较低唤起性消极情绪。积极情绪可用于对BED和AN患者的治疗。

Emotional food craving across the eating disorder spectrum: an ecological momentary assessment study.

Purpose: Emotional eating during negative emotions might underlie disordered eating behavior (i.e., binge eating and food restriction). Positive emotions, by contrast, seem to promote healthier eating behavior. Naturalistic research on the links between emotions and eating across individuals with binge-eating disorder (BED), bulimia nervosa (BN), binge-purge anorexia nervosa (AN-BP), and restrictive anorexia nervosa (AN-R) is, however, lacking.

Methods: Individuals without eating disorders (comparison group, CG, n = 85), and patients with BED (n = 41), BN (n = 50), AN-BP (n = 26), and AN-R (n = 29) participated in an ecological momentary assessment study. Six daily notifications over eight days prompted ratings of momentary food craving and emotional states differing in valence and arousal.

Results: Results supported specific emotion-food-craving patterns in each group. Compared to the CG, arousing negative emotions and higher cravings co-occurred in patients with BN. In patients with AN-BP (at trend level also in patients with AN-R) less arousing negative emotions and lower cravings co-occurred. In patients with AN, positive emotions and higher cravings co-occurred whereas in patients with BED less arousing positive emotions and lower cravings co-occurred.

Conclusion: The found emotion-craving associations may underlie group-specific (dys-)functional eating behaviors, i.e., binge eating and food restriction during negative emotions in patients with BN and AN, and normalized appetitive responses during positive emotions in patients with BED and AN. Therapeutic efforts could target arousing negative emotions in patients with BN, and less arousing negative emotions in patients with AN. Positive emotions could be used in a salutogenetic approach in patients with BED and AN.

期刊介绍: Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity is a scientific journal whose main purpose is to create an international forum devoted to the several sectors of eating disorders and obesity and the significant relations between them. The journal publishes basic research, clinical and theoretical articles on eating disorders and weight-related problems: anorexia nervosa, bulimia nervosa, subthreshold eating disorders, obesity, atypical patterns of eating behaviour and body weight regulation in clinical and non-clinical populations.
