Hypertension is a major global health risk, and social media platforms like TikTok play an increasing role in public health communication. This study evaluates the quality of hypertension-related videos on TikTok and examines the relationship between content quality and user engagement. A systematic keyword search identified hypertension-related videos published before February 25, 2025. After applying exclusion criteria, 139 videos were analyzed. Video quality was assessed using the Journal of the American Medical Association (JAMA) benchmark criteria, the Global Quality Scale (GQS), and the modified DISCERN (mDISCERN) instrument. Engagement metrics (likes, comments, shares, and collections) were recorded, and Spearman's correlation and linear regression analyses explored associations between quality and engagement. These videos accumulated 7190634 likes, 3608023 collections, 247602 comments, and 3252697 shares. Most (85.6%, n = 119) were uploaded by health professionals. The most common JAMA score was 2 (74.8%), while the mean GQS score was 3, with 36.7% of videos receiving this rating. The mDISCERN score was most frequently 2 (71.2%). Video duration correlated with JAMA (β = 0.235, p < 0.05), mDISCERN (β = 0.190, p < 0.05), and GQS scores (β = 0.410, p < 0.001). Likes also correlated with JAMA (β = 0.661, p < 0.001), mDISCERN (β = 0.500, p < 0.05), and GQS scores (β = 0.815, p < 0.001). Comments negatively affected GQS scores (β = -0.574, p < 0.05). TikTok is a valuable platform for hypertension education, but content quality is moderate. Extending video duration, improving rigor, and enhancing review mechanisms may improve hypertension-related health communication.
高血压是全球主要的健康风险，而TikTok等社交媒体平台在公共卫生传播中发挥着越来越重要的作用。本研究评估了TikTok上与高血压相关视频的质量，并考察了内容质量与用户参与度之间的关系。通过系统的关键词搜索，确定了在2025年2月25日之前发布的与高血压相关的视频。应用排除标准后，对139个视频进行了分析。使用美国医学会杂志（JAMA）基准标准、全球质量量表（GQS）和改良的辨别工具（mDISCERN）对视频质量进行评估。记录参与度指标（点赞、评论、分享和收藏），并通过斯皮尔曼相关性分析和线性回归分析探究质量与参与度之间的关联。这些视频累计获得7190634个赞、3608023次收藏、247602条评论和3252697次分享。大多数（85.6%，n = 119）视频由健康专业人员上传。最常见的JAMA评分为2（74.8%），而GQS平均评分为3，36.7%的视频获得该评分。mDISCERN评分最常见为2（71.2%）。视频时长与JAMA评分（β = 0.235，p < 0.05）、mDISCERN评分（β = 0.190，p < 0.05）和GQS评分（β = 0.410，p < 0.001）相关。点赞数也与JAMA评分（β = 0.661，p < 0.001）、mDISCERN评分（β = 0.500，p < 0.05）和GQS评分（β = 0.815，p < 0.001）相关。评论对GQS评分有负面影响（β = -0.574，p < 0.05）。TikTok是高血压教育的一个有价值的平台，但内容质量中等。延长视频时长、提高严谨性和加强审核机制可能会改善与高血压相关的健康传播。
