神经性厌食症（AN）的一个突出障碍是持续限制食物摄入。AN的饮食行为被认为受到焦虑的影响。本研究探讨了AN患者和健康对照个体（HC）的进餐时间焦虑与食物摄入之间的关系。将三项研究（共92例AN和78例HC）的数据合并用于次要数据分析。参与者完成了多项目的实验室自助餐和视觉模拟量表评估餐前和餐后焦虑。线性回归模型评估了进餐焦虑与进餐时卡路里和脂肪摄入量之间的关联，以及诊断组之间的关联是否不同。在患有AN的个体中，餐前焦虑与减少卡路里摄入量和减少膳食中脂肪的卡路里消耗量显著相关;在HC中未观察到这些相关性。没有证据表明任何一组的进餐时卡路里/脂肪摄入量与餐后焦虑之间存在关联。针对进餐时间焦虑的治疗可能会改善AN患者的饮食和营养。通过告知患者餐后焦虑与摄入量无关，可以加强干预措施，如暴露疗法，提供克服进餐焦虑的技能。
A salient disturbance in anorexia nervosa (AN) is the persistent restriction of food intake. Eating behavior in AN is thought to be influenced by anxiety. The current study probed associations between mealtime anxiety and food intake among individuals with AN and healthy comparison individuals (HC). Data were combined across three studies (total of 92 AN and 78 HC) for secondary data analysis. Participants completed a multi-item laboratory buffet meal and visual analogue scale assessments of pre- and post-meal anxiety. Linear regression models assessed the association between mealtime anxiety and calorie and fat intake at the meal, and whether associations differed by diagnostic group. Among individuals with AN, pre-meal anxiety was significantly associated with reduced calorie intake and reduced consumption of calories from fat at the meal; these associations were not observed among HC. There was no evidence for an association between calorie/fat intake at the meal and post-meal anxiety in either group. Treatments that target mealtime anxiety may improve eating and nourishment among individuals with AN. Interventions like exposure therapy that provide skills in overcoming mealtime anxiety might be enhanced by informing patients that post-meal anxiety is not related to intake.
