Web-Based Video Platforms as Sources of Information on Body Image Dissatisfaction in Adolescents: Content and Quality Analysis of a Cross-Sectional Study Background: Body image dissatisfaction among children and adolescents is a significant public health concern and is associated with numerous physical and mental problems. Social media platforms, including TikTok, BiliBili, and YouTube, have become popular sources of health information. However, the quality and reliability of content related to body image dissatisfaction have not been comprehensively evaluated. Objective: The primary goal of this study was to examine the quality and reliability of videos related to body image dissatisfaction on TikTok, BiliBili, and YouTube. Methods: The keywords “body image dissatisfaction” were searched on YouTube™, TikTok, and BiliBili in November 2024. Videos were collected based on platform-specific sort filters, including the filter of “Most liked” on TikTok and the filter of “Most viewed” on BiliBili and YouTube. The top 100 videos on each platform were reviewed and screened in the study. After excluding videos that were (a) not in English or Chinese, (b) duplicates, (c) irrelevant, (d) no audio or visual, (e) contained advertisements, and (f) videos with a GQS score of 1, the final sample consisted of 64 videos, which formed the basis of our research and subsequent findings. Two reviewers screened, selected, extracted data, and evaluated all videos using the Global Quality Scale (GQS), modified DISCERN scores, and the modified Journal of the American Medical Association (mJAMA) benchmark criteria. Statistical analysis was performed using SPSS 28.0. Results: Sixty-four videos were analyzed in the study, including 20 from TikTok, 13 from BiliBili, and 31 from YouTube. The median duration of the involved videos was 3.01 minutes on TikTok, 3.52 minutes on BiliBili, and 4.86 minutes on YouTube. Compared with the other two platforms, BiliBili videos attained higher likes and more comments. The majority of the videos (62.5%) were uploaded by self-media. The quality of the videos on YouTube shows the highest overall scores. Videos uploaded by professional authors had significantly higher GQS, mDISCERN, and mJAMA scores, compared to those uploaded by non-professionals. There was no significant correlation between video quality and the number of views or likes. However, the number of views and likes was significantly positively correlated. Furthermore, a significant correlation was found between the JAMA, Modified DISCERN, and GQS scores. Conclusions: Online video platforms have become an important source for adolescents to access health information. However, the lack of a significant correlation between video quality and the number of likes and comments poses a challenge for users seeking reliable health information. It is suggested that the quality of the videos on health information would be taken into consideration in the recommendation algorithm on online video platforms.

Quality and Dissemination of Uterine Fibroid Health Information on TikTok and Bilibili: Cross-Sectional Study Background: The rise of short-video platforms, such as TikTok (Douyin in China) and Bilibili, has significantly influenced how health information is disseminated to the public. However, the quality, reliability, and effectiveness of health-related content on these platforms, particularly regarding uterine fibroids, remain underexplored. Uterine fibroids are a common medical condition that affects a substantial proportion of women worldwide. While these platforms have become vital sources of health education, misinformation and incomplete content may undermine their efficacy. Objective: This study aims to address these gaps by evaluating the quality and dissemination effectiveness of uterine fibroid-related health information on TikTok and Bilibili. Methods: A total of 200 uterine fibroid-related videos (100 from TikTok and 100 from Bilibili) were selected through a keyword search. The videos were evaluated by two trained gynecological experts using the Global Quality Score (GQS) and a modified version of the DISCERN tool (mDISCERN). Additionally, the Patient Education Materials Assessment Tool for Audio/Visual Materials (PEMAT-A/V) was employed to assess the understandability and actionability of the videos. Statistical analyses, including the Mann-Whitney U test, Spearman rank correlation, and stepwise regression analysis, were used to assess differences between platforms and identify predictors of video quality. Results: The results indicated that TikTok outperformed Bilibili in terms of user engagement metrics such as likes, comments, shares, and followers (all P < .001). However, Bilibili videos were generally longer than those on TikTok (P < .001). The overall quality and reliability of the videos on both platforms were suboptimal, with median GQS scores of 3 (range: 1-5) for TikTok and Bilibili. The median modified DISCERN scores were also low: 2 (range: 1-4) for TikTok and 2 (range: 1-3) for Bilibili, with no significant differences between the two platforms (P = 0.62 for GQS, P = 0.18 for mDISCERN). Both platforms scored similarly on understandability (median PEMAT-U = 77%) and actionability (median PEMAT-A = 67%). Videos uploaded by medical professionals on TikTok had significantly higher quality scores compared to those uploaded by non-professionals. A moderate positive correlation was observed between the GQS and mDISCERN scores (r = 0.41, P < .01), indicating an interrelationship between quality and reliability. Stepwise regression analysis identified "completeness score," "source," and "PEMAT scores" as significant predictors of video quality. Conclusions: This study highlights the generally low quality of uterine fibroid-related health information on short-video platforms, although TikTok showed better performance in terms of engagement and quality. The involvement of medical professionals was found to enhance video quality. These findings underscore the need for improved oversight of health content on social media platforms and greater involvement of healthcare professionals to ensure the dissemination of accurate and reliable health information.
