This study aimed to compare dietary recommendations made in clinical practice guidelines (CPGs) for the management of GDM, evaluate their evidence base, identify research gaps, and assess CPG quality. The PRISMA guidelines were used.
Six databases were searched for CPGs, published between 2000 and 2019, that included dietary advice for the management of GDM.
Two reviewers independently assessed CPG quality (using the AGREE II tool) with respect to dietary recommendations (their strength, evidence base, and research gaps).
Of the 31 CPGs, 68% were assessed as low quality, mainly due to lack of editorial independence. Dietary advice was recommended as the first-line treatment by all CPGs, although the dietary recommendations themselves varied and sometimes were contradictory. Most dietary recommendations were strongly made (70%), but they were often based on very low-quality (54%), or low-quality (15%) evidence. Research gaps were identified for all diet-related recommendations.
High-quality research is needed to improve the evidence base and address the research gaps identified.

本研究旨在比较临床实践指南(CPGs)中针对GDM管理的饮食建议,评估他们的证据基础,确定研究差距,并评估CPG质量。使用PRISMA指南。
在六个数据库中搜索了CPG,发表于2000年至2019年,其中包括GDM管理的饮食建议。
两名评审员独立评估了CPG质量(使用AGREEII工具)关于饮食建议(他们的强度,证据基础,和研究差距)。
在31个CPG中,68%被评估为低质量,主要是由于缺乏编辑独立性。所有CPG都建议将饮食建议作为一线治疗,虽然饮食建议本身各不相同,有时是矛盾的。大多数饮食建议是强烈的(70%),但它们通常基于非常低的质量(54%),或低质量(15%)的证据。确定了所有与饮食相关的建议的研究空白。
需要高质量的研究来改善证据基础并解决已发现的研究空白。
