This study investigates the impact of impulsivity and the mediating role of disinhibited eating behaviour (DEB) on weight and weight trajectories in a large data set including obese non-treatment seeking individuals (obese control, n = 138) and obese individuals who were either receiving a conventional treatment program (n = 227) or bariatric surgery (n = 123). Data was assessed one, 4 and 9 years after baseline including self-reports for impulsivity and DEB. Results suggest a significant association between impulsivity and body mass index, which is partially mediated by DEB. Longitudinally, the influence of impulsivity on the course of weight after 9 years was fully mediated by DEB in obese control but not in the treatment groups. The results indicate an interplay between impulsivity and DEB with respect to obesity. Further research is needed to clarify how the mediation works and when it exerts its effect, in order to identify those that might profit from a specific (impulsivity-reducing) training.

这项研究调查了冲动性对体重和体重轨迹的影响，以及非治疗性肥胖个体（肥胖对照组，n=138）和接受常规治疗计划（n=227）或减肥手术（n=123）的肥胖个体中，冲动性的中介作用。数据评估包括基线后 1、4 和 9 年的自我报告，包括冲动性和抑制性饮食行为。结果表明，冲动性与体重指数显著相关，冲动性部分通过抑制性饮食行为介导。纵向研究表明，在肥胖对照组中，冲动性对 9 年后体重变化的影响完全通过抑制性饮食行为来介导，而在治疗组中则没有。结果表明，冲动性和抑制性饮食行为在肥胖方面存在相互作用。需要进一步的研究来阐明中介作用是如何发挥作用的，以及何时发挥作用，以便确定哪些人可能受益于特定的（减少冲动性）训练。版权所有©2017 约翰威利父子公司和饮食失调协会。
