Regular self-weighing has been a focus of attention recently in the obesity literature. It has received conflicting endorsement in that some researchers and practitioners recommend it as a key behavioral strategy for weight management, while others caution against its use due to its potential to cause negative psychological consequences associated with weight management failure. The evidence on frequent self-weighing, however, has not yet been synthesized. The purpose of this paper is to evaluate the evidence regarding the use of regular self-weighing for both weight loss and weight maintenance.
A systematic literature review was conducted using the MEDLINE, CINAHL, and PsycINFO online databases. Reviewed studies were broken down by sample characteristics, predictors/conditions, dependent measures, findings, and evidence grade.
Twelve studies met the inclusion/exclusion criteria, but nearly half received low evidence grades in terms of methodological quality. Findings from 11 of the 12 reviewed studies indicated that more frequent self-weighing was associated with greater weight loss or weight gain prevention. Specifically, individuals who reported self-weighing weekly or daily, typically over a period of several months, held a 1 to 3 kg/m2 (current) advantage over individuals who did not self-weigh frequently. The effects of self-weighing in experimental studies, especially those where self-weighing behaviors could be isolated, were less clear.
Based on the consistency of the evidence reviewed, frequent self-weighing, at the very least, seems to be a good predictor of moderate weight loss, less weight regain, or the avoidance of initial weight gain in adults. More targeted research is needed in this area to determine the causal role of frequent self-weighing in weight loss/weight gain prevention programs. Other open questions to be pursued include the optimal dose of self-weighing, as well as the risks posed for negative psychological consequences.
定期自我称重最近在肥胖文献中受到关注。它的接受程度存在争议，一些研究人员和从业者建议将其作为体重管理的关键行为策略，而另一些人则警告不要使用，因为它可能导致与体重管理失败相关的负面心理后果。然而，关于频繁自我称重的证据尚未得到综合。本文旨在评估定期自我称重在减肥和维持体重方面的使用证据。
使用 MEDLINE、CINAHL 和 PsycINFO 在线数据库进行系统文献综述。综述研究根据样本特征、预测因素/条件、因变量、发现和证据等级进行分类。
符合纳入/排除标准的研究有 12 项，但几乎一半的研究在方法学质量方面的证据等级较低。12 项综述研究中的 11 项研究结果表明，更频繁的自我称重与更大的减肥或体重增加预防相关。具体来说，与不频繁自我称重的个体相比，报告每周或每天自我称重（通常持续几个月）的个体体重减轻或增重的优势为 1 至 3 公斤/平方米（当前）。在实验研究中，自我称重的效果，特别是在可以孤立自我称重行为的情况下，不太清楚。
基于综述的证据一致性，频繁自我称重至少似乎是中度减肥、体重减少后不易反弹或避免初始体重增加的良好预测指标。在这一领域需要进行更有针对性的研究，以确定频繁自我称重在减肥/增重预防计划中的因果作用。其他需要探讨的开放性问题包括自我称重的最佳剂量，以及对负面心理后果的风险。
