High‐quality systematic reviews (SR) and meta‐analyses (MA) are considered to be reliable sources of information. This study aims to assess the quality of studies published as SR or MA in the field of bariatrics in 2016 and 2017. We identified SR and MA in the field of bariatrics by searching electronic databases (MEDLINE, Embase, and Cochrane Database of Systematic Reviews). Eligible studies were those identified as SR/MA in the title/abstract, which aimed to assess any outcome in patients with morbid obesity undergoing or scheduled to undergo bariatric surgery. Two authors independently reviewed all titles and abstracts, assessed full texts of potentially eligible studies, and assessed the quality of included studies. Any discrepancies were resolved by the third reviewer. We evaluated the quality and risk of bias of each SR/MA using AMSTAR 2 checklist and ROBIS tool, respectively. Seventy‐eight of 4236 references met inclusion criteria and were assessed for their quality/risk of bias. The methodological quality of 99% of all papers was classified as “critically low.” A total of 6% of the studies were at low risk of bias, and 78% were assessed as being at high risk of bias. The methodological quality of studies published in 2016 and 2017 as SR/MA is highly unsatisfactory.

在减肥领域发表的系统评价/荟萃分析的质量：使用 AMSTAR 2 和 ROBIS 的横断面系统调查。

高质量的系统评价 (SR) 和荟萃分析 (MA) 被认为是可靠的信息来源。本研究旨在评估 2016 年和 2017 年在减肥领域发表的 SR 或 MA 研究的质量。我们通过搜索电子数据库（MEDLINE、Embase 和 Cochrane 系统评价数据库）确定了减肥领域的 SR 和 MA . 符合条件的研究是那些在标题/摘要中标识为 SR/MA 的研究，旨在评估正在或计划进行减肥手术的病态肥胖患者的任何结果。两位作者独立审查了所有标题和摘要，评估了可能符合条件的研究的全文，并评估了纳入研究的质量。任何差异都由第三位评审员解决。我们分别使用 AMSTAR 2 检查表和 ROBIS 工具评估了每个 SR/MA 的质量和偏倚风险。4236 篇参考文献中有 78 篇符合纳入标准，并对其质量/偏倚风险进行了评估。99% 的论文的方法论质量被归类为“极低”。共有 6% 的研究存在低偏倚风险，78% 的研究被评估为存在高偏倚风险。2016 年和 2017 年作为 SR/MA 发表的研究的方法学质量非常不能令人满意。
