Abstract：
There is an increasing trend in the use of internet as a search tool for health-related informations. Insulin resistance is one of the most searched subjects online and some of the videos about insulin resistance have been watched by millions of YouTube users. This study aims to determine the quality and reliability of the most popular videos about insulin resistance on YouTube.
On March 1, 2022, the term \"insulin resistance\" was searched on YouTube. The videos\' popularity was assessed with Video Power Index (VPI). The quality and reliability were assessed with DISCERN score, modified DISCERN score and global quality score (GQS).
A total of 100 most popular videos were evaluated after applying the exclusion criteria. Fifty-four percent of the videos were very poor-poor, 35 % moderate, and 11 % good-excellent quality. Although few in number, the videos with relatively higher quality and more reliable had higher numbers of views, likes and comments (p < 0.01). There was a positive correlation between DISCERN score and VPI, duration, view, like, dislike, comment numbers of the videos (p < 0.01). Healthcare providers uploaded 58 % of the videos, while independent users uploaded 42 %. Video like ratio (VLR) at healthcare providers\' videos was significantly higher than independent users\' videos (p = 0.001).
Despite the high viewing rates of YouTube videos about insulin resistance, the overall quality and reliability were found to be very low. However, when high quality content regarding popular medical topics is produced, more people can be informed correctly.

摘要：
目的：使用互联网作为健康相关信息的搜索工具的趋势越来越大。胰岛素抵抗是网上搜索最多的主题之一，数百万YouTube用户已经观看了一些关于胰岛素抵抗的视频。这项研究旨在确定YouTube上最受欢迎的关于胰岛素抵抗的视频的质量和可靠性。
方法：2022年3月1日，在YouTube上搜索了“胰岛素抵抗”一词。使用视频功率指数（VPI）评估了视频的受欢迎程度。质量和可靠性用DISCERN评分进行评估，修正的DISCERN评分和全球质量评分(GQS)。
结果：在应用排除标准后，共评估了100个最受欢迎的视频。54%的视频非常贫穷，35%中等,和11％的良好-优良的品质。虽然数量很少，质量相对较高、较可靠的视频观看次数较多，喜欢和评论（p<0.01）。DISCERN评分与VPI呈正相关,持续时间,视图,喜欢,不喜欢,视频的评论号(p<0.01)。医疗保健提供者上传了58%的视频，而独立用户上传了42%。医疗保健提供商的视频相似率（VLR）显着高于独立用户的视频（p=0.001）。
结论：尽管YouTube上关于胰岛素抵抗的视频观看率很高，整体质量和可靠性非常低。然而,当产生关于热门医学主题的高质量内容时，更多的人可以被正确地告知。
