摘要

Social media platforms, particularly short-video applications, have emerged as crucial channels for disseminating public health information. Human papillomavirus (HPV) infection in males represents a significant sexually transmitted disease burden with under-addressed health impacts. Despite its prevalence, the quality of HPV-related content targeting male audiences on these platforms remains unevaluated, posing potential risks to public health literacy. We conducted a cross-sectional analysis of 265 TikTok and Bilibili videos addressing male HPV infection. Video reliability and educational quality were assessed using the modified DISCERN (mDISCERN) instrument and Global Quality Scale (GQS). The study used statistical analysis to examine the content and quality of videos on the two platforms, the identities of the uploaders and the correlations between these factors and user engagement data. Overall video quality was low (median GQS = 2.00; mDISCERN = 2.00). TikTok outperformed Bilibili in both engagement metrics and quality scores (GQS: TikTok median = 2.00 [IQR 2.00–3.00] vs. Bilibili = 2.00 [2.00–2.00], p < 0.01; mDISCERN: 2.00 [2.00–3.00] vs. 2.00 [2.00–2.00]). Content gaps were prominent: only 15.8% (n = 42) covered prevention strategies (e.g., vaccination), while symptom descriptions dominated (29.8%). Specialist-generated videos scored significantly higher in quality (GQS = 3.00 [2.00–3.00]; mDISCERN = 2.00 [2.00–3.00]) than non-specialist content (GQS = 2.00 [2.00–2.00]; mDISCERN = 2.00 [2.00–2.00]). Engagement metrics showed no correlation with quality scores. Short-video platforms exhibit suboptimal quality in disseminating male HPV information, with TikTok marginally superior to Bilibili. Specialist involvement enhances content reliability, underscoring the importance of leveraging professional health communication on social media. Public health initiatives must prioritise engaging experts to amplify accurate prevention messaging, particularly regarding vaccination, and address current informational inequities, thereby improving community health outcomes.
