Obesity interventions typically involves some form of dietary restraint (i.e., intentional limiting of food intake), yet the restraint model of binge eating proposes that engaging in dietary restraint is a causal factor for binge-eating symptoms. Evidence for this model has been mixed and differs by measures, study design, and sample. Further, there also may be moderators of the association of dietary restraint and binge eating. The purpose of this systematic review was to compile the current evidence on moderators of the association of dietary restraint and binge eating. A literature search was conducted across electronic databases, resulting in inclusion of 16 papers (with 15 different samples). Reviewed studies were primarily heterosexual White college student females and were primarily cross-sectional studies with self-report measures. There were no consistent moderators across the studies. Yet, there was some evidence for interactions between affective constructs and dietary restraint in relation to binge eating as well as three-way interactions between affect, cognitive constructs, and dietary restraint. Although there were few studies, there was little current evidence for social, biological, and demographic factors as moderators. Overall, our systematic review shows a need for further research to clarify and validate moderators, and to understand complex interactions as well as potential causal relationships between restraint and binge-eating behaviors.
肥胖干预通常涉及某种形式的饮食限制（即有意限制食物摄入量），然而暴饮暴食的限制模型提出，进行饮食限制是暴饮暴食症状的一个因果因素。该模型的证据参差不齐，因测量方法、研究设计和样本而异。此外，饮食限制与暴饮暴食之间的关联可能也存在调节因素。本系统综述的目的是汇总关于饮食限制与暴饮暴食之间关联的调节因素的现有证据。我们在多个电子数据库中进行了文献检索，最终纳入了16篇论文（涉及15个不同样本）。纳入综述的研究主要是异性恋白人女大学生，且主要是采用自我报告测量方法的横断面研究。各项研究中没有一致的调节因素。不过，有一些证据表明，在暴饮暴食方面，情感构念与饮食限制之间存在相互作用，以及情感、认知构念与饮食限制之间存在三方相互作用。尽管研究较少，但目前几乎没有证据表明社会、生物学和人口统计学因素可作为调节因素。总体而言，我们的系统综述表明，需要进一步开展研究，以阐明和验证调节因素，并了解限制与暴饮暴食行为之间的复杂相互作用以及潜在因果关系。
