Abstract

Objective: Mealtimes are highly distressing for individuals with eating disorders (ED), potentially reinforcing disordered eating and complicating recovery. Yet, physiological responses during meals remain understudied. This study explores autonomic nervous system responses during meals in individuals with ED and healthy controls (HC).

Methods: Three studies assessed heart rate (HR), heart rate variability (HRV), skin conductance response (SCR), and skin temperature (ST) around lunchtime. Study 1 included 47 hospitalized adult women with ED (26 anorexia nervosa (AN), 8 atypical AN, 13 bulimia nervosa (BN)). Studies 2 and 3 involved 47 and 58 HC in daily life.

Results: Patients reported elevated subjective stress but showed no expected physiological responses in HR. Instead, HR decreased during meals for all patients and increased after in those with BN. No significant changes were observed in HRV or SCR. No ST changes were observed in AN, while BN showed the expected pre-lunch decrease and post-lunch increase. In HC, HR and SCR rose pre-meal, HRV decreased, and ST increased during meals.

Discussion: These findings suggest a mismatch between subjective and physiological stress in ED. Chronic stress or undernutrition may alter autonomic reactivity, although not directly assessed. Future research should investigate how these factors shape physiological stress responses.

饮食失调和健康对照者的进餐时生理反应

目的：进餐时间对饮食失调（ED）患者来说是非常痛苦的，可能会加剧饮食失调并使康复复杂化。然而，进餐时的生理反应仍未得到充分研究。本研究探讨了ED患者和健康对照组（HC）用餐时的自主神经系统反应。方法：三项研究评估了午餐前后的心率（HR）、心率变异性（HRV）、皮肤电导反应（SCR）和皮肤温度（ST）。研究1纳入47例ED住院成年女性患者，其中神经性厌食症26例，非典型神经性厌食症8例，神经性贪食症13例。研究2和3涉及日常生活中的47和58个HC。结果：患者报告主观应激升高，但在HR中没有表现出预期的生理反应。相反，所有患者的HR在用餐期间都有所下降，而BN患者的HR在用餐后有所增加。HRV或SCR未见明显变化。在AN中没有观察到ST的变化，而BN表现出预期的午餐前减少和午餐后增加。在HC中，HR和SCR在餐前升高，HRV降低，ST在餐后升高。讨论：这些发现表明ED患者的主观和生理应激不匹配。慢性应激或营养不良可能改变自主神经反应性，尽管没有直接评估。未来的研究应探讨这些因素如何影响生理应激反应。

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.
