This research explored whether orthorexia nervosa is associated with deficits in executive function.
A non-clinical sample of participants (n = 405; 80% women, 53% white, mean age = 24, mean body mass index = 25) completed the Orthorexia Nervosa Inventory (ONI) and the Behavior Rating Inventory of Executive Function-Adult version (BRIEF-A).
ONI scores were weakly to moderately correlated with all BRIEF-A scales (p < 0.001 for eight scales, p < 0.05 for one scale), exhibiting the greatest correlations with the scales assessing behavioral regulation: Emotional Control (r = 0.34), Inhibition (r = 0.30), Set Shifting (r = 0.25), and Self-Monitoring (r = 0.28). Hierarchical regression analyses revealed that eight of these nine relationships remained significant (p < 0.001 for five scales including all behavioral regulation scales, p < 0.01 for two scales, p < 0.05 for one scale) after controlling for demographic variables (e.g., gender, body mass index, age, education level) and diagnoses of an eating disorder, obsessive-compulsive disorder, attention deficit/hyperactivity disorder, autism, and learning disability.
These findings suggest that, despite unique manifestations, orthorexia and anorexia may possess an overlapping neuropsychological profile marked by deficits in executive function, which may negatively impact daily life.
Level V, descriptive cross-sectional study.
本研究旨在探讨饮食失调是否与执行功能缺陷有关。
研究采用非临床参与者样本（n=405；80%为女性，53%为白人，平均年龄为 24 岁，平均体重指数为 25），完成了饮食强迫症量表（ONI）和行为评定量表的成人版（BRIEF-A）。
ONI 得分与 BRIEF-A 的所有量表呈弱至中度相关（p<0.001 为 8 个量表，p<0.05 为 1 个量表），与评估行为调节的量表相关性最大：情绪控制（r=0.34）、抑制（r=0.30）、转换（r=0.25）和自我监测（r=0.28）。层次回归分析显示，这九个关系中的八个在控制人口统计学变量（例如性别、体重指数、年龄、教育水平）和饮食失调、强迫症、注意力缺陷/多动障碍、自闭症和学习障碍的诊断后仍然显著（p<0.001 为五个量表，包括所有行为调节量表，p<0.01 为两个量表，p<0.05 为一个量表）。
这些发现表明，尽管有独特的表现形式，饮食失调和厌食症可能具有重叠的神经心理学特征，表现为执行功能缺陷，这可能会对日常生活产生负面影响。
