目的探讨自我称重频率和一致性对减肥维持的促进作用。参与者是74名成年人，他们完成了为期3个月的基于互联网的减肥计划，随后是9个月的无干预维持期。自我称重的频率定义为参与者在维护期间通过研究提供的智能秤进行自我称重的天数。一致性被定义为参与者以一定频率自我称重的周数，并检查了多个最低阈值。层次回归分析用于评估维持期间频率、一致性和体重变化之间的关联。当定义为参与者在>= 6天/周或7天/周时自我称重的周数时，一致性越高，体重反弹越少（P值< 0.05）。与假设相反，频率与权重变化无关（P = 0.141），频率与一致性之间没有显著的相互作用。结果表明，在减肥计划结束后，自我称重的一致性可能比总频率更重要，以防止体重反弹。此外，结果表明，高水平的一致性（自称体重为>= 6天/周或7天/周）可能是促进成功减肥维持所必需的。
Objective This study aimed to investigate the roles of frequency and consistency of self-weighing in promoting weight-loss maintenance.Methods Participants were 74 adults who completed a 3-month internet-based weight-loss program followed by a 9-month no-intervention maintenance period. Frequency of self-weighing was defined as the number of days that participants self-weighed during the maintenance period via a study-provided smart scale. Consistency was defined as the number of weeks that participants self-weighed at a certain frequency, with multiple minimum thresholds examined. Hierarchical regression analyses were used to assess associations among frequency, consistency, and weight change during the maintenance period.Results Greater consistency was significantly associated with less weight regain when defined as the number of weeks that participants self-weighed on >= 6 d/wk or 7 d/wk (P values < 0.05). Contrary to hypotheses, frequency was not associated with weight change (P = 0.141), and there was not a significant interaction between frequency and consistency.Conclusions Results demonstrate that consistency of self-weighing may be more important than total frequency for preventing weight regain after the end of a weight-loss program. Further, results suggest that a high level of consistency (self-weighing for >= 6 d/wk or 7 d/wk) may be necessary to promote successful weight-loss maintenance.
