近三分之一的大学生超重或肥胖。失控饮食是一种因情绪或外部因素引起的对食物消费缺乏自我约束的现象，在大学生中普遍存在，可能是针对这一人群的干预目标。无饥饿饮食（EAH）是一种不受抑制的饮食形式，已在儿童和青少年中进行了广泛研究，但对大学生中 EAH 的调查很少。在这项研究中，对评估儿童和青少年持续和开始 EAH 的有效措施进行了修改，并在自由生活的大学人群中进行了评估（n = 457；84% F；24.5 +/- 7.6 岁；23.4 +/- 4.8 kg/m(2)）。分为三个潜在因素（情绪、外部和身体）的九个子量表解释了连续 EAH 中的 68% 的方差，而分组为相同潜在因素的一组单独的九个子量表解释了开始 EAH 中的 71% 的方差（Cronbach's alpha：连续 EAH 为 0.82，开始 EAH 为 0.81）。 Female sex and sedentary behavior were significantly related to continual EAH, relationships driven by scores for the emotion factor, and to beginning EAH, relationships driven by scores for the physical factor.仅对于持续 EAH，BMI 与情绪因素相关性较弱 (p = 0.06)。在大学人群中，久坐的生活方式与 EAH（持续的和开始的 EAH）相关的观察结果是一项新颖的发现，并揭示了一种缓解 EAH 的可能策略。 (C) 2015 Elsevier Ltd. 保留所有权利。
Nearly one-third of college students are overweight or obese. Disinhibited eating, a phenomenon defined as the lack of self-restraint over food consumption prompted by emotional or external factors, is prevalent among college students and may be a target for intervention in this population. Eating in the absence of hunger (EAH) is a form of disinhibited eating that has been studied extensively in children and adolescents, but there is little investigation of EAH among college students. In this research, a validated measure for assessing continual and beginning EAH in children and adolescents was modified and assessed in a free-living college population (n = 457; 84% F; 24.5 +/- 7.6 years; 23.4 +/- 4.8 kg/m(2)). Nine subscales grouped into three latent factors (emotion, external, and physical) accounted for 68% of the variance in continual EAH, and a separate set of nine subscales grouped into the same latent factors accounted for 71% of the variance in beginning EAH (Cronbach's alpha: 0.82 for continual EAH and 0.81 for beginning EAH). Female sex and sedentary behavior were significantly related to continual EAH, relationships driven by scores for the emotion factor, and to beginning EAH, relationships driven by scores for the physical factor. BMI was weakly related to the emotion factor (p = 0.06) for continuing EAH only. The observation that a sedentary lifestyle was associated to EAH (both continuing and beginning EAH) in a college population is a novel finding and reveals a possible strategy to moderate EAH.
