This preregistered study examined associations between empirically derived profiles of disordered eating in a diverse nonclinical sample and three facets of gastrointestinal (GI) interoception (visceral sensitivity, hunger responsiveness, satiety responsiveness). University students ( = 591; 53.3% women; 23.0% Hispanic) completed the Visceral Sensitivity Index, Adult Eating Behavior Questionnaire, and Eating Pathology Symptom Inventory. Latent profile analysis was conducted in Mplus v8.3 with four behavioral indicators (restricting, binge eating, excessive exercise, purging [binary]). Facets of GI interoception predicting odds of disordered eating profile membership compared to an asymptomatic group were evaluated. Five profiles were identified. Facets of GI interoception differentially predicted odds of membership in disordered eating profiles. However, higher scores on all three facets of GI interoception were associated with increased odds of membership in a high disordered eating profile. The relationship between distinct facets of GI interoception and specific disordered eating patterns appears nuanced, though individuals displaying a range of disordered eating behaviors may exhibit broad GI interoceptive dysfunction. Findings are consistent with the recent emphasis on idiographic treatment approaches for disordered eating and may have implications for screening among university students. Prospective longitudinal work and extension to clinical samples is needed.

内脏敏感性、饥饿反应性和饱腹感反应性：本科生样本中胃肠道内感受与饮食失调之间的关联

这项预先注册的研究检查了不同非临床样本中凭经验得出的饮食失调概况与胃肠道 (GI) 内感受的三个方面（内脏敏感性、饥饿反应性、饱腹感反应性）之间的关联。大学生（= 591；53.3% 女性；23.0% 西班牙裔）完成了内脏敏感性指数、成人饮食行为问卷和饮食病理学症状调查表。在 Mplus v8.3 中使用四种行为指标（限制、暴饮暴食、过度运动、净化[二元]）进行潜在概况分析。与无症状组相比，对胃肠道内感受预测饮食失调的可能性进行了评估。确定了五份资料。胃肠道内感受的各个方面对饮食失调的概率有不同的预测。然而，胃肠道内感受的所有三个方面的得分较高与高度饮食失调的几率增加相关。胃肠道内感受的不同方面与特定的饮食失调模式之间的关系似乎很微妙，尽管表现出一系列饮食失调行为的个体可能表现出广泛的胃肠道内感受功能障碍。研究结果与最近强调饮食失调的具体治疗方法是一致的，并且可能对大学生筛查具有影响。需要进行前瞻性纵向工作并扩展到临床样本。
