摘要
目的 通过证据图方法系统识别、描述和评价膳食减糖策略的有效性.方法 计算机检索CNKI、WanFang Data、VIP、CBM、PubMed、Embase、Web of Science 和 Cochrane Library 数据库,搜集膳食减糖策略有效性的系统评价/Meta分析,检索时限均从建库至2022年11月10日.采用AMSTAR-2对纳入研究进行方法学质量评估,利用Excel 2019软件设计数据提取表,提取相关关键信息,采用气泡图综合呈现干预类型、系统评价/Meta分析纳入研究数量、结论分类等信息.结果 共纳入11篇系统评价/Meta分析.纳入研究根据不同干预措施特点总结为10项干预类型,其中行为改变策略、健康饮食、糖税、物质替代、糖标签、社区干预的研究结局表现出明显有效性,而社会认知模型、减糖指南、健康素养、知识态度行为模型则少有明确的有益效果,说明在理论基础上的干预类型收效甚微.结论 目前证据图显示行为改变策略、健康饮食、糖税、物质替代、糖标签、社区干预具有有效性,同时也存在健康素养、知识态度行为模型等有效性不明确的减糖策略和干预空白.且基于理论方面的膳食减糖策略的有效性证据相对匮乏,未来仍需高质量的研究进一步探讨.
Abstract
Objective The effectiveness of systematic identification,description and evaluation of dietary sugar reduction strategies through the evidence diagram method.Methods The CNKI,WanFang Data,VIP,CBM,PubMed,Embase,Web of Science and Cochrane Library database were electronically searched to collect systematic reviews/meta-analysis on the effectiveness of dietary sugar reduction strategies from inception to November 10,2022,AMSTAR-2 was used to evaluate the methodological quality of the included studies.Microsoft Excel 2019 was used to design a data extraction table to extract relevant key information.Bubble charts were used to comprehensively present information such as study population,intervention type,number of primary studies included,and outcome measures.Results A total of 11 papers were included,all of which were systematic reviews/meta-analysis.The studies included ten interventions.Among them,the research ending of behavioral changes strategies,healthy diet,sugar tax,material substitution,sugar label,and community intervention showed obvious effectiveness,while social cognitive models,sugar reduction guidelines,health literacy,and knowledge attitude behavior models had not shown a clear and beneficial effect,indicating that the intervention effect on the theoretical basis was very small.Conclusion The current evidence diagram shows that the sugar reduction strategy is effective,but there are also intervention conclusions that the effectiveness of the conclusion is not clear and intervention blank.And based on the theoretical dietary sugar reduction strategy,the validity evidence is relatively scarce.In the future,high quality research will still be required.
