NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Reliability, Quality, and Science popularity of Diabetes Knowledge Information in China Video Sharing Platform: A Cross-sectional Study
ABSTRACT
Background:
More and more diabetes individuals are using internet video platforms for self-management of blood glucose in China. TikTok, WeChat and Bilibili, have gained popularity because of the easy access to health information. However, the quality, reliability and science popularity of health information on these platforms have still not been fully assessed, and studies comparing the three platforms are lacking.
Objective:
A cross-sectional study was established to evaluate the reliability, quality and science popularity of diabetes health information in Chinese Internet video platforms.
Methods:
This study used 'diabetes' as a keyword to identify the top 100 videos meeting the specified criteria on each platform, resulting in 300 videos. The modified DISCERN score, the Journal of the American Medical Association Score (JAMAS) benchmark criteria, and Global Quality Scores (GQS) were employed to assess the reliability of videos. This study developed criteria to evaluate the scientific popularity of the platforms. Each video was assessed based on the health information categories recommended by the Chinese Diabetes Guidelines (2022).
Results:
Of the videos retrieved, 68.67% (206/300) were released by certified medical professionals. Diet was the most frequently discussed topic (83%). TikTok achieved the lowest DISCERN scores (median 2, IQR:2.00) compared with Bilibili (median 3, IQR: 2.00) and WeChat (median 3, IQR: 0.00). The median JAMA criterion score was 3 (IQR:1.00) for all three platforms. The science popularity score of Bilibili (median 80, IQR: 13.75) was highest. The overall GQS quality of Bilibili (median: grade 3) and WeChat (median: grade 3) was higher than the TikTok platform (median 2). Among diabetes guideline scores, the highest median score was Bilibili (median 2, IQR: 3.00), which was higher than TikTok (median 1, IQR 1.00) and WeChat (median 1, IQR 1.00). The science popularity of medical professionals was significantly lower than non-medical professionals.
Conclusions:
Information from Chinese Internet video platforms is generally of fairly reliable quality. Bilibili received the best quality, reliability and popularity of science compared with TikTok and WeChat. All three platforms cover little information about medication. Health professionals should be encouraged to produce high-quality diabetes health science popularization works to enhance the standard of scientific communication.
