Obesity and being overweight are major risk factors for metabolic syndrome and non-communicable diseases. Despite the recommendation that a healthy diet and physical activity can reduce the severity of these diseases, many fail to adhere to these measures. From a behavioural economic perspective, adherence to such measures can be encouraged through financial incentives. However, additional related behavioural economic approaches may improve the effectiveness of an incentive programme. As such, we have developed a protocol for a systematic review and network meta-analysis to summarise the current evidence from financial incentive programmes with and without behavioural economic insights for promoting healthy diet and physical activity.
Previous systematic reviews, meta-analyses and individual studies were identified from Medline and Scopus in June 2020 and will be updated until December 2020. Individual studies will be selected and data extracted by two reviewers. Disagreement will be resolved by consensus or adjudicated by a third reviewer. A descriptive analysis will summarise the effectiveness of behavioural economic incentive programmes for promoting healthy diet and physical activity. Moreover, individual studies will be pooled using network meta-analyses where possible. I statistics and Cochran's Q test will be used to assess heterogeneity. Risk of bias and publication bias, if appropriate, will be evaluated, as well as the overall strength of the evidence.
Ethics approval for a systematic review and meta-analysis is not required. The findings will be published in a peer-reviewed journal.

肥胖和超重是代谢综合征及非传染性疾病的主要风险因素。尽管建议健康饮食和体育活动可降低这些疾病的严重程度，但许多人并未坚持这些措施。从行为经济学角度来看，可通过经济激励来鼓励人们坚持这些措施。然而，其他相关的行为经济学方法可能会提高激励计划的有效性。因此，我们制定了一项系统评价和网络荟萃分析方案，以总结目前来自有或没有行为经济学见解的经济激励计划在促进健康饮食和体育活动方面的证据。
2020年6月从Medline和Scopus数据库中检索之前的系统评价、荟萃分析及单项研究，并将更新至2020年12月。由两名评审员选择单项研究并提取数据。分歧将通过共识解决或由第三名评审员裁决。描述性分析将总结行为经济学激励计划在促进健康饮食和体育活动方面的有效性。此外，如有可能，将使用网络荟萃分析对单项研究进行汇总。将使用I统计量和 Cochr an Q检验来评估异质性。将评估偏倚风险和发表偏倚（如适用）以及证据的总体强度。
系统评价和荟萃分析无需伦理批准。研究结果将发表在同行评审期刊上。
