A Quality, Reliability, and Dissemination Characteristics of Pneumoconiosis-Related Videos on TikTok and Bilibili: A Cross-Sectional Study
This cross-sectional study reveals that while pneumoconiosis-related videos on Bilibili and TikTok offer moderate quality information, there is a significant mismatch between user engagement and content reliability, with TikTok's high-traffic content often being of lower quality compared to Bilibili's more in-depth educational material, highlighting an urgent need for platform-specific strategies to improve the dissemination of evidence-based occupational health guidance.

Every day, millions of people turn to their phones to learn about their health, seeking answers in the quick, scrolling streams of short videos. These platforms have become a primary source of medical information, replacing traditional pamphlets and doctor's offices for many. However, the speed at which this information travels often comes at the cost of accuracy. When it comes to pneumoconiosis, a severe and irreversible lung disease caused by breathing in dust like silica or coal, the stakes are incredibly high. Because there is no cure for this condition, the only way to protect workers is through strict prevention and early detection. If the public receives misleading advice or false hope from online videos, they might delay seeking proper medical help, leading to permanent lung damage and unnecessary suffering. Understanding what kind of information is actually reaching these workers is therefore a critical public health question.
Researchers set out to investigate the landscape of pneumoconiosis videos on two of China's most popular video platforms, TikTok and Bilibili. They wanted to know not just how many videos existed, but whether the information they contained was reliable, how well it was presented, and whether the most popular videos were also the most accurate. To find the answers, the team gathered a large collection of videos from both sites, carefully filtering out advertisements and duplicate content until they had a final set of 166 videos to study. They then evaluated each video using several standard tools designed to measure the quality of health information, checking for things like whether the sources were cited, if the advice was balanced, and if the content was clear and useful. They also tracked how many people liked, shared, saved, or commented on each video to see how the public was reacting to different types of content.
The study revealed a striking divide between the two platforms. Videos on TikTok were generally shorter, newer, and received significantly more likes and comments than those on Bilibili. However, when it came to the actual quality of the medical information, Bilibili came out ahead. Videos on Bilibili tended to be longer and more detailed, often taking the form of documentaries, lectures, or case reports that explained the disease in depth. In contrast, TikTok videos were dominated by doctors giving quick, direct advice or showing short clinical scenarios. While the doctors on TikTok were verified professionals, the content they produced often lacked the depth and evidence-based sourcing found on the other platform. The researchers found that the overall quality of information across both sites was only moderate, with many videos failing to clearly state their sources or acknowledge the limits of their advice.
Perhaps the most concerning finding was the relationship between popularity and quality. On TikTok, the videos that received the most engagement were often the ones with the lowest quality scores. This suggests that on this platform, content that is simple, emotional, or sensational tends to spread faster than content that is scientifically rigorous. Videos uploaded by patients, which often focused on personal struggles and emotional stories, generated massive amounts of interaction, yet they frequently offered the least reliable medical information. On Bilibili, the pattern was different; higher-quality videos tended to receive more positive engagement, indicating that the audience there is more willing to watch and appreciate in-depth educational content. Despite these differences, both platforms shared a significant gap: very few videos focused on prevention. Most content concentrated on treating the disease or explaining what it is, leaving out the crucial information about how to avoid getting sick in the first place.
The researchers concluded that while social media offers a powerful way to reach the public, the current flow of information about pneumoconiosis is flawed. The most visible content is often not the most trustworthy, and the most important message—prevention—is largely missing. To fix this, health experts and platform managers need to work together to ensure that high-quality, evidence-based information is not buried by viral but inaccurate content. This might involve changing how videos are recommended to users, requiring clearer labels for medical advice, and encouraging creators to make prevention a central part of their storytelling. Without these changes, the workers who need this information the most may continue to be misled by the very tools meant to help them.
