Pediatric pneumonia remains a major global health concern, accounting for one of the leading causes of mortality among children under five years of age. With the prevalence of COVID-19, public attention to pediatric pneumonia has significantly increased. In recent years, short video platforms such as Bilibili, TikTok, and Kwai-boasting billions of global users-have emerged as critical channels for disseminating and accessing health-related information. This study systematically evaluates the quality and reliability of pediatric pneumonia-related short videos on the aforementioned three platforms.
We employed the Chinese keyword "Pneumonia in Children" to conduct searches on Bilibili, TikTok, and Kwai, selected the top 100 recommended related videos of each platform, and extracted and recorded the title, website, publisher, content, duration, days since published, and audience engagement metrics (Likes, Comments, Saves) of each video. The Global Quality Scale (GQS), modified DISCERN (mDISCERN), and Medical Quality Video Evaluation Tool (MQ-VET) were used to evaluate video quality and reliability. Finally, statistical analyses were conducted to compare quality differences among different platforms, different types of publishers, and different video content.
Significant variations in audience engagement metrics (likes, comments, and saves) were observed across the three platforms (p < 0.01), with TikTok demonstrating the highest values for all metrics. The categorization of video content and publisher types exhibited statistically significant heterogeneity among the platforms (p < 0.001). Videos created by medical professionals exhibited significantly elevated quality and reliability assessment scores in comparison to content generated by non-medical practitioners (p < 0.001). Bilibili consistently achieved the highest scores across all evaluation tools (GQS, mDISCERN, and MQ-VET scores; p < 0.001), particularly for content produced by medical professionals. Compared with News and reports, videos focused on disease Disease knowledge and Treatment and prevention received significantly higher scores (p < 0.001). Notably, a negative correlation was identified between video quality scores and audience engagement metrics(p < 0.05).
The overall quality of video content on the three platforms Bilibili, TikTok, and Kwai is average, with low reliability, among which Bilibili's video quality and reliability are higher than the other two platforms. Meanwhile, videos published by medical professionals have better quality and higher reliability.
小儿肺炎仍然是全球主要的健康问题，是五岁以下儿童主要死因之一。随着新冠疫情的流行，公众对小儿肺炎的关注度显著提高。近年来，哔哩哔哩、抖音和快手等拥有数十亿全球用户的短视频平台已成为传播和获取健康相关信息的重要渠道。本研究系统评估了上述三个平台上与小儿肺炎相关的短视频的质量和可靠性。
我们使用中文关键词“小儿肺炎”在哔哩哔哩、抖音和快手上进行搜索，选取每个平台上推荐的前100个相关视频，并提取和记录每个视频的标题、网址、发布者、内容、时长、发布天数以及观众参与度指标（点赞、评论、收藏）。使用全球质量量表（GQS）、改良的辨别力量表（mDISCERN）和医学质量视频评估工具（MQ-VET）来评估视频质量和可靠性。最后，进行统计分析以比较不同平台、不同类型发布者和不同视频内容之间的质量差异。
在三个平台上观察到观众参与度指标（点赞、评论和收藏）存在显著差异（p < 0.01），抖音在所有指标上的值最高。视频内容和发布者类型的分类在各平台之间表现出统计学上的显著异质性（p < 0.001）。与非医学从业者制作的内容相比，医学专业人员制作的视频在质量和可靠性评估得分上显著更高（p < 0.001）。哔哩哔哩在所有评估工具（GQS、mDISCERN和MQ-VET得分）上始终获得最高分（p < 0.001），特别是医学专业人员制作的内容。与新闻和报道相比，专注于疾病知识以及治疗和预防的视频得分显著更高（p < 0.001）。值得注意的是，视频质量得分与观众参与度指标之间存在负相关（p < 0.05）。
哔哩哔哩、抖音和快手这三个平台上视频内容的整体质量一般，可靠性较低，其中哔哩哔哩的视频质量和可靠性高于其他两个平台。同时，医学专业人员发布的视频质量更好，可靠性更高。
