To evaluate the quality of oral cancer information in Brazilian Portuguese on Google, YouTube, and Instagram.
The first 100 links of each platform characterized the initial sample. The websites and Instagram were evaluated using the JAMA benchmarks, the Discern instrument, and the Flesch readability index (Flesch Reading Ease). The existence of Health on the Net (HON) code was also registered on websites. The usefulness of each video on YouTube was classified as not useful, slightly useful, moderately useful, or very useful.
Thirty-four websites, 39 Instagram posts, and 57 videos were evaluated, of which 18 (33.3%) websites and 19 (48.7%) Instagram posts covered only 2 of the 4 JAMA benchmarks. For the Discern instrument, 20 (37%) and 18 (33.3%) websites exhibited low and moderate reliability, respectively, while 26 (66.7%) Instagram posts were of low confidence. The level of intelligibility of both websites and Instagram was difficult. Only three websites exhibited the HONcode. Forty-one (71.9%) videos on YouTube were moderately useful.
Information on oral cancer on the Internet in Brazilian Portuguese is of low quality. Thus, educational and governmental institutions have a responsibility to produce and indicate reliable sources of information for the population.
评估谷歌、YouTube 和 Instagram 上巴西葡萄牙语口腔癌信息的质量。
每个平台的前 100 个链接构成了初始样本。使用 JAMA 基准、Discern 工具和 Flesch 阅读难度指数（Flesch Reading Ease）评估网站和 Instagram。还记录了网站上是否存在健康网络（HON）代码。YouTube 上的每个视频的有用性被归类为无用、有点用、比较有用或非常有用。
评估了 34 个网站、39 个 Instagram 帖子和 57 个视频，其中 18 个（33.3%）网站和 19 个（48.7%）Instagram 帖子仅涵盖了 4 个 JAMA 基准中的 2 个。对于 Discern 工具，20 个（37%）和 18 个（33.3%）网站的可靠性分别为低和中，而 26 个（66.7%）Instagram 帖子的可信度较低。网站和 Instagram 的可理解性水平都很难。只有三个网站显示了 HON 代码。YouTube 上的 41 个（71.9%）视频比较有用。
互联网上巴西葡萄牙语的口腔癌信息质量较低。因此，教育和政府机构有责任为民众提供可靠的信息来源。
