Quality of low back pain (LBP) information offered on YouTube ™ is unclear.
To describe the current low back pain information available on YouTube ™ and determine if these videos report information that aligns with clinical guidelines. Further analysis explored whether specific features of the videos explain their popularity.
A cross-sectional observational study was conducted on videos related to LBP on YouTube™ with the 200 most viewed videos using the term "low back pain." The videos were independently viewed and assessed by two researchers for specific video characteristics, LBP specific content, and compliance with guidelines. The association between video characteristics or content with popularity (i.e., views, likes, dislikes, and comments) was investigated using regression models.
The median number of views was 2 018 167. Only 59 (29.5%) of the videos reported at least one diagnostic recommendation from clinical guidelines, and only 100 (50%) reported a treatment recommendation that aligned with clinical guidelines. Apart from year of upload, no variables were identified that were independently associated with popularity or engagement of the videos.
The information related to LBP offered on YouTube™ is often not evidence-based and there is the tendency to prioritize information on interventions rather than understanding the LBP process. Factors related to engagement with content about LBP on YouTube™ remains uncertain, indicating further need for knowledge translation in this field.
YouTube ™ 上提供的腰痛（LBP）信息质量尚不清楚。
描述 YouTube ™ 上当前可用的腰痛信息，并确定这些视频是否报告与临床指南一致的信息。进一步的分析探讨了视频的特定特征是否解释了它们的受欢迎程度。
对 YouTube ™ 上与 LBP 相关的视频进行了一项横断面观察性研究，使用术语“low back pain”查看了前 200 个最受欢迎的视频。这些视频由两名研究人员独立观看和评估，以评估特定视频特征、LBP 具体内容以及与指南的一致性。使用回归模型调查视频特征或内容与受欢迎程度（即观看次数、点赞、不喜欢和评论）之间的关联。
中位数观看次数为 2 018 167。只有 59 个（29.5%）视频报告了至少一个临床指南的诊断建议，只有 100 个（50%）视频报告了与临床指南一致的治疗建议。除上传年份外，未发现与视频受欢迎程度或参与度独立相关的变量。
YouTube ™ 上提供的与 LBP 相关的信息通常没有循证依据，并且存在优先关注干预措施信息而不是了解 LBP 过程的倾向。与 YouTube ™ 上关于 LBP 的内容参与相关的因素尚不确定，这表明在该领域进一步需要知识转化。
