注意缺陷多动障碍(ADHD)和特质冲动的症状与饮食紊乱有关，但很少在社区研究中进行评估，或纵向评估，对其中介机制知之甚少。我们横向测试了ADHD症状和饮食紊乱之间的关系，以及特质冲动和纵向饮食紊乱之间的关系。我们使用的数据来自一个标准的年轻人队列(642名参与者：65%是女性，MAGE=23岁)。参与者被归类为饮食紊乱的高风险或低风险。在横截面和纵向分层Logistic回归模型的前两步中，输入了人口统计学和协变量。横断面回归分析采用成人注意缺陷多动自评量表(ASRS)评分，分为注意力不集中和多动/冲动两类症状。在单独的纵向模型中，Barratt冲动性量表的子量表(注意冲动性、运动冲动性和非计划性冲动性)进入第三步。用情绪和感觉问卷(MFQ)评估抑郁情绪，并将其作为中介变量。在横断面上，性别、MFQ评分和注意力不集中症状预测进食障碍的风险(模型R2=20%)。纵向上，性别、MFQ得分和注意冲动预测进食障碍的风险(模型R2=16%)。注意力不集中症状与进食障碍风险之间的关系在MFQ得分中起部分中介作用，而注意冲动与进食障碍风险之间的关系则完全通过MFQ得分起中介作用。这些数据突出了(1)注意力不集中的ADHD症状的特定作用，以及(2)抑郁和冲动在预测进食障碍风险方面的重要性。
Symptoms of attention deficit hyperactivity disorder (ADHD) and trait impulsivity have been associated with disordered eating but are seldom assessed in community studies, or longitudinally and little is known about the mediating mechanisms. We tested associations between ADHD symptoms and disordered eating cross-sectionally and between trait impulsivity and disordered eating longitudinally. We utilised data from a normative cohort of young adults (642 participants: 65% female, Mage = 23 years). Participants were classified as high risk or low risk for disordered eating using the SCOFF instrument. In the first two steps of both cross-sectional and longitudinal hierarchical logistic regression models, demographics and covariates were entered. For the cross-sectional regression, Adult ADHD self-report scale (ASRS) scores, separated into inattentive and hyperactive/impulsive symptoms, were entered in the third step. In a separate longitudinal model, Barratt impulsivity scale subscales (attentional, motor and non-planning impulsivity) were entered in the third step. Depression, as assessed by the moods and feelings questionnaire (MFQ), was examined as a mediator. Cross-sectionally, sex, MFQ score and inattentive symptoms predicted disordered eating risk (model R2 = 20%). Longitudinally, sex, MFQ score and attentional impulsivity predicted disordered eating risk (model R2 = 16%). The relationship between inattentive symptoms and the disordered eating risk was partially mediated by MFQ score, whereas the relationship between attentional impulsivity and the disordered eating risk was fully mediated by MFQ scores. These data highlight (1) a specific role for inattentive symptoms of ADHD and (2) the importance of both depression and impulsivity in predicting eating disorder risk.
