神经性厌食症（AN）是一种严重的精神疾病，其特征是热量摄入减少，通常在急性体重恢复后持续存在。这项初步研究评估了最近体重恢复的AN患者餐前焦虑和食物摄入之间的关系。我们假设餐前焦虑与AN的热量摄入呈负相关。卡路里摄入量和餐前焦虑在3个基于实验室的评估（酸奶零食，多项目午餐，通心粉和奶酪午餐）中测量。在进餐前通过施皮伯格状态-特质焦虑量表（STAI-S）测量焦虑。急性体重恢复的AN患者与健康对照（HC）进行了比较。焦虑和摄入量之间的关联首先在每种膳食类型中单独分析，然后使用模型将样本联合收割机组合。在多项目午餐和通心粉和奶酪午餐中，AN吃得明显少于HC（p = 0.01，p<0.001）。餐前焦虑与AN的摄入量显著相关，但与HC无关。在酸奶零食中，患者或对照组的焦虑和摄入量之间没有显着关联，并且各组在热量摄入方面没有差异。餐前焦虑和摄入量之间的关联与AN的体重恢复的个人建议复发预防治疗的潜在目标。
Anorexia Nervosa (AN) is a serious mental illness characterized by reduced caloric intake that often persists after acute weight restoration. This preliminary study assesses the relationship between pre-meal anxiety and food intake in recently weight-restored individuals with AN. We hypothesized that pre-meal anxiety is inversely related to caloric intake in AN. Caloric intake and pre-meal anxiety were measured in 3 laboratory- based assessments (yogurt snack, multi-item lunch, macaroni and cheese lunch). Anxiety was measured by Spielberger State-Trait Anxiety Inventory (STAI-S) administered prior to the meal. Acutely weight-restored patients with AN were compared with healthy controls (HC). Associations between anxiety and intake were analyzed first within each meal type separately and then using a model to combine the sample. In the multi-item lunch and the macaroni & cheese lunch, AN ate significantly less than HC (p = 0.01, p<0.001). Pre-meal anxiety was significantly correlated with intake among AN, but not HC. In the yogurt snack, there was no significant association between anxiety and intake among patients or controls, and the groups did not differ in caloric intake. The association between pre-meal anxiety and intake among weight restored individuals with AN suggests a potential target for relapse prevention treatment.
