To evaluate the information quality of hypertension-related videos on the TikTok short video platform and assess their potential value for public health education.
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.
The 177 videos received 11 250 432 likes, 366 588 comments, 3 265 929 favorites, and 3 780 513 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).
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.
