BACKGROUND: Allergic Rhinitis (AR) affects over 500 million people globally, posing a significant public health burden. Video-sharing platforms like YouTube and Bilibili have become primary sources of health information. This study aimed to compare content quality, user engagement, and alignment with seasonal search trends of AR-related videos on these two culturally distinct platforms. METHODS: We retrieved the top 200 AR-related videos from each platform (keywords: "allergic rhinitis" for YouTube, "" for Bilibili) published between January 2022 and January 2025. After applying predefined exclusion criteria (irrelevance, non-English YouTube videos, out-of-timeframe, advertisements), 240 videos (91 YouTube, 149 Bilibili) were retained. Quality was assessed using the Patient Education Material Assessment Tool (PEMAT), Video Information Quality Index (VIQI), Global Quality Scale (GQS), and the Modified DISCERN Scale (mDISCERN). We also integrated Google Trends and Baidu Index data to analyze video characteristics, engagement, and correlations with seasonal search trends. RESULTS: AR-related video quality was generally low, though YouTube scored significantly higher than Bilibili in median PEMAT-Total (76.5 vs. 71.4), GQS (4 vs. 3), and mDISCERN (3 vs. 1) (all P < 0.001). YouTube featured more content from medical professionals (33.3%, n = 30/91), whereas Bilibili's was predominantly from non-professionals (61.4%, n = 92/149). Bilibili showed higher user engagement, with greater...
