Background Inflammatory Bowel Disease (IBD) is a chronic condition with increasing global prevalence. Short-video platforms like TikTok and Bilibili are popular health information sources, but their IBD-related content quality remains uncertain. Objective To assess the quality and reliability of IBD-related videos on TikTok and Bilibili. Methods We analyzed the top 100 IBD-related videos from each platform (200 total). Quality was evaluated using Global Quality Scale (GQS), modified DISCERN (mDISCERN), and JAMA benchmarks. Engagement metrics and quality scores were correlated. Results TikTok videos had higher engagement (P < .001) and better median scores (GQS: 3, mDISCERN: 3, JAMA: 3) than Bilibili (GQS: 3, mDISCERN: 3, JAMA: 3; P < .05). Gastroenterologist-created videos scored highest. GQS correlated positively with engagement (r = 0.16–0.26, P < .05), while mDISCERN correlated only with likes, shares, and saves (r = 0.16–0.18, P < .05). JAMA scores negatively correlated with duration (r = −0.24, P < .001). Conclusions IBD-related short videos showed moderate quality, with TikTok outperforming Bilibili. Gastroenterologist-produced content was most reliable. Viewers should critically evaluate such health information to avoid misinformation.
