摘　　要：目的本研究旨在评价抖音短视频平台高血压相关视频的信息质量,并评估其对公众健康教育的潜在应用价值。方法2024年6月,以“高血压”为关键词在抖音短视频平台检索,筛选前200个视频,最终纳入177个视频进行质量评价。使用结构化内容完整性评估工具和DISCERN视频质量评估工具进行评价,并研究视频质量与视频特征(时长、点赞、评论、收藏和转发)之间的相关性。结果177个视频共获得11250432个点赞、366588条评论、3265929次收藏和3780513次转发。视频时长中位数为111秒(74,158),上传天数中位数为672天(147,878)。89.3%的视频由医生发布,个人科学传播者占8.5%,新闻机构占2.3%。98.9%的视频有字幕,所有视频均有人物出现,仅有26.0%包含动画演示。内容完整性各维度评分:定义0.19±0.40、症状0.11±0.32、风险因素0.29±0.50、评估0.36±0.45、管理0.81±0.47和结局0.63±0.58。90.4%的视频DISCERN评分在≤50分,其质量为“一般”或以下;不同发布者之间的DISCERN评分无显著差异(P>0.05)。DISCERN评分与视频时长显著相关(r=0.409,P<0.001)。结论抖音短视频平台高血压相关视频整体质量较低,视频时长与质量之间显著正相关,而高质量视频的关注度较低。由于信息质量和可靠性较低,抖音短视频平台并不是一个适合用于高血压科普教育的知识来源。Objective To evaluate the information quality of hypertension-related videos on the TikTok short video platform and assess their potential value for public health education.Methods In June 2024,we searched the TikTok short video platform using the keyword"hypertension"selecting the top 200 videos and ultimately including 177 videos for quality evaluation.Structured content integrity assessment tools and the DISCERN video quality assessment tool were used to evaluate the videos.The correlation between video quality and characteristics(duration,likes,comments,favorites,and shares)was studied.Results The 177 videos received 11250432 likes,366588 comments,3265929 favorites,and 3780513 shares.The median video length was 111 seconds(74,158),and the median upload days were 672 days(147,878).89.3%of the videos were posted by doctors,8.5%by individual science communicators,and 2.3%by news agencies.98.9%of the videos had subtitles,all featured individuals,and only 26.0%included animated demonstrations.Content integrity scores were:definition 0.19±0.40,symptoms 0.11±0.32,risk factors 0.29±0.50,assessment 0.36±0.45,management 0.81±0.47,and outcomes 0.63±0.58.90.4%of the videos had a DISCERN score of≤50,indicating"average"or below quality,with no significant difference in DISCERN scores among different publishers(P>0.05).DISCERN scores were significantly correlated with video duration(r=0.409,P<0.001).Conclusion The overall quality of hypertension-related videos on TikTok is low,with a significant positive correlation between video duration and quality.High-quality videos receive less attention,making TikTok an unsuitable platform for hypertension education due to low information quality and reliability.
