The present study evaluated the cross-section and prospective associations between the Eating Inventory's (EI) total, flexible and rigid dietary restraint scales and changes in weight and behaviors in a community sample of adults enrolled in a 3 y weight gain prevention study.
Subjects were participants in the Pound of Prevention (POP) study, a community-based weight gain prevention trial.
Higher levels of baseline total, flexible and rigid dietary restraint were related to lower weight and more weight-controlling behaviors at the baseline assessment. Baseline restraint measures positively predicted increases in weighing frequency over the 3 y follow-up. Increases in restraint over the follow-up period were related to decreases in weight, energy intake and television watching, and increases in self-weighing and physical activity.
The EI's total, flexible and rigid restraint scales were not differently associated with weight and behaviors in this heterogeneous sample of adults who were attempting to lose weight. Developing methods to increase behavioral and cognitive strategies to control weight may help to prevent weight gain in clinical and community samples.
本研究评估了饮食量表（EI）的总量表、灵活和严格饮食限制量表与参加一项为期3年体重增加预防研究的社区成年样本的体重变化及行为之间的横断面关联和前瞻性关联。
受试者参与了“预防磅数（POP）”研究，这是一项基于社区的体重增加预防试验。
在基线评估中，较高水平的基线总量表、灵活和严格饮食限制与较低体重及更多体重控制行为相关。基线限制测量结果正向预测了3年随访期间称重频率的增加。随访期间限制的增加与体重、能量摄入和看电视时间的减少，以及自我称重和身体活动的增加相关。
在这个试图减肥的成年异质样本中，EI的总量表、灵活和严格限制量表与体重及行为的关联并无差异。开发增加控制体重的行为和认知策略的方法，可能有助于在临床和社区样本中预防体重增加。
