The quality and reliability of short videos about premature ovarian failure on Bilibili and TikTok: Cross-sectional study
Abstract
Background Premature ovarian failure (POF) is a condition where ovarian function ceases before age 40, leading to infertility and other health issues. As public health awareness increases, platforms like TikTok and Bilibili have become key sources for health-related content. However, the absence of peer review and regulatory oversight on short-video platforms may result in the spread of inaccurate or incomplete health information. This study evaluates the quality of videos related to POF on these platforms. Methods A cross-sectional study was conducted, analyzing 187 POF-related videos from TikTok and Bilibili. The modified DISCERN and Global Quality Score (GQS) assessment tools were used to evaluate video reliability and quality. Data on video characteristics, including engagement metrics and content, were also collected. Statistical analyses were performed to assess differences between platforms, video sources, and video quality. Result TikTok is more popular than Bilibili. Videos on both platforms related to POF had suboptimal quality, with TikTok's GQS median at 3 (2–3) and Bilibili's at 2 (1–3), showing a significant difference (p 0.05). On Bilibili, video duration was positively correlated with quality scores (p < 0.001), but no such correlation was found on TikTok. Symptoms of POF were the most common topic, with 29% of videos providing detailed explanations. Diagnosis and treatment were discussed in 16% and 7.4% of videos, respectively. Expert-uploaded videos…
