While TikTok has gained popularity as a social media platform for sharing HF-related information, the quality of such content on TikTok remains unexplored.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross-sectional analysis was conducted on TikTok videos related to HF in China. The sources of the videos were identified and analyzed. The content comprehensiveness of the videos was evaluated using six questions that covered definition, signs and symptoms, risk factors, evaluation, management, and outcomes. The reliability and quality of the videos were assessed using three standardized evaluation instruments: DISCERN, JAMA benchmarks, and the Global Quality Scale. Additionally, the correlation between video quality and video characteristics was further investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among the video sources, 92.2% were attributed to health professionals, while news agencies and non-profit organizations accounted for 5.7% and 2.1%, respectively. The content comprehensiveness score for the videos was 3.36 (SD 3.56), with news agencies receiving the highest scores of 4.06 (SD 3.31). The median DISCERN, JAMA, and GQS scores for all 141 videos were 26.50 (IQR 25.00\u201328.750), 2.00 (IQR 2.00\u20132.00), and 2.00 (IQR 2.00\u20132.00), respectively. Videos from health professionals had significantly higher JAMA scores compared to those from non-profit organizations (<jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.01). Correlation analysis between video quality and video characteristics showed positive correlations between content comprehensiveness scores and video duration (<jats:italic>r<\/jats:italic>\u2009=\u20090.420, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.001), number of comments (<jats:italic>r<\/jats:italic>\u2009=\u20090.195, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.05), and number of shares (<jats:italic>r<\/jats:italic>\u2009=\u20090.174, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.05). GQS scores were negatively or positively correlated with the number of days since upload (<jats:italic>r<\/jats:italic>\u2009=\u2009\u22120.212, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.05) and video duration (<jats:italic>r<\/jats:italic>\u2009=\u20090.442, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The overall quality of the videos was found to be unsatisfactory, with variations in quality scores observed across different video sources. Content comprehensiveness was inadequate, the reliability and quality of the information presented in the videos was questionable. As TikTok continues to grow as a platform for health information, it is essential to prioritize accuracy and reliability to enhance patients\u2019 self-care abilities and promote public health.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpubh.2023.1315393","type":"journal-article","created":{"date-parts":[[2023,12,11]],"date-time":"2023-12-11T10:08:21Z","timestamp":1702289301000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":57,"title":["TikTok video as a health education source of information on heart failure in China: a content analysis"],"prefix":"10.3389","volume":"11","author":[{"given":"Xun","family":"Gong","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Dong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danping","family":"Shen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiyi","family":"Rong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,12,11]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"3272","DOI":"10.1093\/cvr\/cvac013","article-title":"Global burden of heart failure: a comprehensive and updated review of epidemiology","volume":"118","author":"Savarese","year":"2022","journal-title":"Cardiovasc Res"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"606","DOI":"10.1161\/HHF.0b013e318291329a","article-title":"Forecasting the impact of heart failure in the United States.
