保持减肥对于减少肥胖相关的健康损害至关重要。然而，只有少数人能够长期成功地保持减肥。研究提供了初步证据，证明与体重有关的戏弄（WRT）和更大的非规范饮食行为之间存在关联。此外，第一个证据发现了非规范饮食行为和减肥维持之间的关联。因此，本研究旨在探讨WRT对维持减肥的预测价值，以及非规范饮食行为作为这种关系的可能中介的作用。这项研究是德国体重控制登记处的一部分，该登记处前瞻性地跟踪了那些故意减掉最大体重至少10%并保持这种减轻的体重至少一年的人。在N = 381名参与者中，回顾性研究了儿童和青少年时期的WRT，目前的非规范饮食行为（即，限制、外部、情绪化饮食），以及体重指数（BMI，kg/m2）的变化，采用自我报告评估。结构方程模型被用来分析假设的中介关系。因此，在儿童期和青春期进行回顾性WRT的效果更大，预测在两年内维持成人体重减轻的成功率更低。当前的情绪化饮食完全调解这一关系，而当前的限制和外部饮食没有产生中介作用。因此，WRT的更大影响预测了当前更大的情绪化饮食，这反过来又预测了BMI的较小下降或较大增加。我们的研究结果表明，在儿童和青少年时期患有WRT可能会导致情绪化饮食，这反过来又会损害长期减肥的维持。因此，我们的结果强调需要采取干预措施，旨在减少体重耻辱并针对情绪化饮食，以成功维持长期减肥。(C)2016爱思唯尔有限公司版权所有
Weight loss maintenance is essential for the reduction of obesity-related health impairments. However, only a minority of individuals successfully maintain reduced weight in the long term. Research has provided initial evidence for associations between weight-related teasing (WRT) and greater non normative eating behaviors. Further, first evidence was found for associations between non-normative eating behaviors and weight loss maintenance. Hence, the present study aimed to examine the predictive value of WRT for weight loss maintenance and the role of non-normative eating behaviors as possible mediators of this relationship. The study was part of the German Weight Control Registry that prospectively followed individuals who had intentionally lost at least 10% of their maximum weight and had maintained this reduced weight for at least one year. In N = 381 participants, retrospective WRT during childhood and adolescence, current non-normative eating behaviors (i.e., restrained, external, emotional eating), and change in body mass index (BMI, kg/m(2)) over two years were examined using self-report assessments. Structural equation modeling was used to analyze the assumed mediational relationship. As a result, a greater effect of retrospective WRT during childhood and adolescence predicted less successful adult weight loss maintenance over two years. Current emotional eating fully mediated this relationship while current restrained and external eating yielded no mediational effects. Hence, a greater effect of WRT predicted greater current emotional eating, which in turn predicted a smaller decrease or a greater increase in BMI. Our findings suggest that suffering from WRT during childhood and adolescence might lead to emotional eating which in turn impairs long-term weight loss maintenance. Thus, our results highlight the need for interventions aiming at reducing weight stigmatization and targeting emotional eating for successful long-term weight loss maintenance. (C) 2016 Elsevier Ltd.
