有必要确定有效的减肥行为策略。自我权衡可能就是这样一种策略。检查自我称重减肥的有效性。一项随机对照试验的系统性综述和荟萃分析，包括将自我称重作为一项单独的干预措施或作为干预措施的一个组成部分。我们使用分组来分析称重指令（每日和每周）频率的差异，以及是否包括问责制影响体重减轻。只有一项研究将自我称重作为单一策略进行检查，没有证据表明其有效（-0.5 kg 95% CI -1.3至0.3）。4项试验在多组分方案中增加了自我称重/自我调节技术，并产生了-1.7 kg的显著差异（95%CI-2.6至-0.8）。比较多组分干预（包括自称重）与无干预或最低限度控制的15项试验的显著平均差异为-3.4 kg（95% CI -4.2至-2.6）。每周或每日称重的干预措施无显著差异。在包括问责制的试验中，体重减轻显著更大（p = 0.03）。缺乏证据表明，建议在没有其他干预成分的情况下进行自我称重是否有效。在行为减肥计划中增加自我称重可能会改善体重减轻。包括自我称重在内的行为减肥计划比最低限度的干预措施更有效。问责制可以提高包括自我权衡在内的干预措施的有效性。本文的在线版本（doi：10.1186/s12966-015-0267-4）包含补充材料，可供授权用户使用。
There is a need to identify effective behavioural strategies for weight loss. Self-weighing may be one such strategy. To examine the effectiveness of self-weighing for weight loss. A systematic review and meta-analysis of randomised controlled trials that included self-weighing as an isolated intervention or as a component within an intervention. We used sub groups to analyse differences in frequency of weighing instruction (daily and weekly) and also whether including accountability affected weight loss. Only one study examined self-weighing as a single strategy and there was no evidence it was effective (-0.5 kg 95 % CI -1.3 to 0.3). Four trials added self-weighing/self-regulation techniques to multi-component programmes and resulted in a significant difference of -1.7 kg (95 % CI -2.6 to -0.8). Fifteen trials comparing multi-component interventions including self-weighing compared with no intervention or minimal control resulted in a significant mean difference of -3.4 kg (95 % CI -4.2 to -2.6). There was no significant difference in the interventions with weekly or daily weighing. In trials which included accountability there was significantly greater weight loss (p = 0.03). There is a lack of evidence of whether advising self-weighing without other intervention components is effective. Adding self-weighing to a behavioural weight loss programme may improve weight loss. Behavioural weight loss programmes that include self-weighing are more effective than minimal interventions. Accountability may improve the effectiveness of interventions that include self-weighing.
