Uterine fibroids, the most common monoclonal benign tumors of the uterine smooth muscle, show an increasing incidence with age. Currently, social media platforms such as TikTok, YouTube, and Bilibili are increasingly becoming important channels for disseminating health information. However, the quality and reliability of content related to uterine fibroids on these platforms are often unsatisfactory. This study aims to systematically evaluate the quality and content characteristics of uterine fibroid-related videos on 3 major short-video platforms – TikTok, YouTube, and Bilibili – using validated assessment tools. A total of 300 videos (100 per platform) uploaded between 2020 and 2025 were included. Video quality was assessed using the The Journal of the American Medical Association benchmark criteria, modified DISCERN instrument, and Global Quality Score. Content features, uploader identity, presentation format, and engagement metrics were also analyzed. Statistical analyses included nonparametric tests and Spearman correlation. Bilibili consistently outperformed TikTok and YouTube in all quality metrics (The Journal of the American Medical Association, DISCERN, Global Quality Score), though overall video quality across platforms was moderate. Video duration was positively correlated with quality scores (ρ ≈ 0.33 for DISCERN). No significant associations were found between engagement metrics (likes/comments) and professional quality ratings. Key content features such as animated demonstrations, source attribution, and inclusion of recent research advances were significantly associated with higher quality. Overall, content across all platforms exhibits deficiencies. However, videos related to uterine fibroids on Bilibili demonstrate relatively fewer shortcomings, while notable quality disparities persist among the different platforms. Content creators should prioritize videos of 2 to 10 minutes with evidence-based features to improve reliability. Viewers are advised to focus on content depth and source credibility rather than superficial engagement metrics. Enhanced platform regulation and public awareness are urgently needed.
