Abstract

Weight suppression (WS), the difference between an individual's current and highest adult weight, is predictive of eating-related pathology across diagnostic categories and poor eating disorder treatment outcomes, but findings from non-clinical samples have been mixed. Cravings are strong urges for specific foods that are subjectively difficult to resist. Food cravings are now widely conceptualized as cognitive-affective states characterized by intrusive thoughts that are perceived as distressing and can interfere with adaptive functioning. Food cravings are known antecedents of binge eating, but little is known about how they interact with WS. We examined the obsessive-compulsive aspects of food cravings as potential moderators of the association between WS and eating disorder symptoms in general, and binge eating specifically in a cross-sectional study of college students. Participants ( = 144, 60.4% female) self-reported their height and current and past highest adult weight and completed the Binge Eating Scale (BES), Eating Disorder Examination-Questionnaire (EDE-Q), and Obsessive Compulsive Eating Scale (OCES). Main and interactive effects of WS and OCES scores on EDE-Q global and BES scores were examined in regression models. There were significant main effects of OCES scores on overall eating disorder symptom severity as well as binge frequency, with those endorsing more craving-related intrusive thoughts and compulsive urges engaging in maladaptive behaviors more frequently. WS alone did not consistently cross-sectionally predict eating disorder psychopathology. Findings suggest that food cravings are significantly associated with disordered eating symptoms and specifically binge eating frequency and should be accounted for in future research on WS in clinical and non-clinical samples.

摘要

体重抑制(WS),即个体当前体重与最高成年体重之间的差异,可预测各类诊断中的饮食相关病理状况以及不良的饮食失调治疗结果,但非临床样本的研究结果却参差不齐。渴望是对特定食物的强烈欲望,主观上难以抗拒。现在,食物渴望被广泛概念化为认知 - 情感状态,其特征是侵入性思维,这些思维被认为令人痛苦且会干扰适应性功能。食物渴望是暴饮暴食已知的先兆,但它们与体重抑制如何相互作用却知之甚少。在一项针对大学生的横断面研究中,我们考察了食物渴望的强迫方面,将其作为体重抑制与一般饮食失调症状之间关联的潜在调节因素,尤其关注与暴饮暴食的关联。参与者(n = 144,60.4%为女性)自我报告了身高、当前和过去的最高成年体重,并完成了暴饮暴食量表(BES)、饮食失调检查问卷(EDE - Q)和强迫性饮食量表(OCES)。在回归模型中考察了体重抑制和强迫性饮食量表得分对饮食失调检查问卷总分和暴饮暴食量表得分的主要及交互作用。强迫性饮食量表得分对总体饮食失调症状严重程度以及暴饮暴食频率有显著的主要影响,那些认可更多与渴望相关的侵入性思维和强迫冲动的人更频繁地参与适应不良行为。仅体重抑制在横断面研究中并不能一致地预测饮食失调的精神病理学。研究结果表明,食物渴望与饮食紊乱症状显著相关,特别是与暴饮暴食频率相关,在未来临床和非临床样本中关于体重抑制的研究中应予以考虑。
