Dissemination of Mask Effectiveness Misinformation Using TikTok as a Medium

Assessing the quality of educational short videos on dry eye care: a cross-sectional study

Background

Short video social media platforms play a crucial role in public health by effectively disseminating health information. Despite this, many educational videos on dry eye care have not received sufficient attention. This study aimed to conduct a comprehensive analysis and evaluate the quality of educational short videos on dry eye care available on TikTok.

Methods

On August 30, 2024, the top 200 videos related to dry eye were viewed from the Chinese version of TikTok using the platform's default ranking. The overall quality, reliability, comprehensibility, and applicability of the videos are systematically evaluated using the DISCERN and PEMAT-A/V assessment tools.

Results

A total of 199 videos were included in the study and categorized based on account information: medical professional individual users, general professional individual users, for-profit organizations, non-profit organizations, and news organizations. Medical professionals were the predominant uploaders, contributing 81% of the videos. The overall misinformation rate was 2%. A majority of the videos (85.9%) addressed at least two aspects of dry eye, while only 14.1% covered three or more topics. The videos scored 22.4 ± 6.4 for reliability and 17.4 ± 6.2 for treatment options. Upon evaluation, the understandability and actionability of these videos were found to be 79.1% and 60.4%, respectively.

Conclusion

TikTok holds significant potential for disseminating health information, primarily through content created by medical professionals. Currently, much of the content focuses on the symptoms and management of dry eye, with limited discussion on its definition, classification, and diagnosis. While most video content is reliable, there is a risk of incomplete or inaccurate information, these videos can serve as a reference. Therefore, the public should exercise caution when seeking information on dry eye through TikTok and individuals experiencing symptoms are advised to consult healthcare professionals for accurate diagnosis and treatment.

Quality of information and social norms in Spanish-speaking TikTok videos as levers of commercial practices: The case of semaglutide

Social media can be a platform to spread misinformation and reinforce potentially harmful norms in the interest of commercial actors. There are norms related to obesity that commercial actors promote such as "obesity is an individual problem" and the "pharmaceuticalization of obesity". In this study, we assess the quality of information about semaglutide, and the descriptive norms related to its use as levers of commercial practices in social media. We carried out a content analysis of Spanish speaking TikTok videos published between January 2022 and November 2023. We used the DISCERN instrument to assess the quality of information and classified the social norms disseminated through the videos and the narrating voices. The overall quality of information was low, with a mean DISCERN score of 29.8 out of 75. Although healthcare professionals and professional communicators performed slightly better compared to other voices, critical aspects of good health communication were often lacking; 155 videos (71%) did not mention any risk related to the use of semaglutide and only 11.9% of videos mentioned one or more serious risks. In 85% of videos, obesity was depicted as an individual problem. About half of the videos normalized the use of semaglutide and 79% of videos promoted the pharmaceuticalization of obesity by mentioning losing weight as a benefit of using semaglutide but not mentioning the need to make lifestyle changes. The combination of poor-quality health information and the promotion of potentially harmful norms related to semaglutide use is a public health concern. Further research on the commercial determinants of health in the context of semaglutide use is needed, as well as actions to mitigate the risks of misinformation and harmful health-related norms.

Quality assessment of heatstroke videos on TikTok

Background

The prevalence of heatstroke is rising due to global warming, making it a serious but preventable condition, highlighting the urgent need for effective dissemination of relevant health education to the general public. Advances in technology have made accessing health information more convenient and rapid. In recent years, short videos have become a primary medium for delivering health education, with TikTok gaining considerable popularity among the general public. However, the quality of heatstroke-related health education content on TikTok deserves closer scrutiny.

Objective

This study aimed to evaluate the quality and content of heatstroke-related videos available on TikTok.

Methods

The present study analyzed the top 100 heatstroke-related short videos on TikTok, focusing on their characteristics, quality, and the content they conveyed. The quality of these videos was assessed using the DISCERN instrument. In addition, the completeness of the videos was assessed by examining six key aspects: disease definition, clinical manifestations, risk factors, assessment, management, and outcomes.

Results

The study included a total of 90 videos. The results showed that news organizations and healthcare professionals were the primary contributors to these videos, with those from news organizations receiving the most attention. In contrast, those from healthcare professionals received comparatively less engagement. Overall, the quality of the information was found to be moderately low, with the highest quality videos posted by non-profit organizations, followed by those posted by healthcare professionals. The majority of videos uploaded described the disease definition, clinical presentation, risk factors, assessment, management, and outcomes of heatstroke.

Conclusion

The quality of information provided in heatstroke-related short videos on TikTok is generally inadequate and requires significant improvement. In addition, such content should be subject to government review to ensure its accuracy and reliability.

Popular contraception videos on TikTok: An assessment of content topics

OBJECTIVES

This study aimed to explore the contraception content topics on the highly popular social media platform TikTok to understand this influential information source patients may bring into birth control counseling visits.

STUDY DESIGN

Utilizing a snapshot method, we collected the 100 most popular TikTok English-language videos for each of the eight contraception-specific search terms. We abstracted video content topics addressed and creator attributes. Two independent abstractors coded each video with high agreement, with a third coder adjudicating discrepancies.

RESULTS

The final data set included 700 unique videos, with a total of 1.18 billion views, 131 million likes, 1.5 million comments, and 4.1 million shares. In these videos, the most common topics addressed were patient experience (n = 365, 52.1%) and logistics of use (n = 351, 50.1%). Health care professionals created only 19.3% of videos (n = 135), but these videos accounted for a larger portion of the total video views (41.3%). Health care professionals largely made educational videos (92.6%) compared to 22.5% of videos coded as educational videos when made by perceived non-health care professionals. A small number of prolific video creators developed the majority of videos made by health care professionals, with 91 (67.4%) made by six TikTok creators.

CONCLUSIONS

TikTok contains highly accessible contraception content, which garners high viewership, especially when created by health care providers. Clinicians should be aware of TikTok's potential to influence patients prior to contraceptive counseling visits and recognize this platform as a public health instrument to disseminate contraceptive information to a key demographic.

IMPLICATIONS

Few previous studies have examined the presence and popularity of contraception content topics on TikTok; little is known about the health content on this highly popular platform. Providers should be aware of the contraceptive topics on TikTok for understanding both patient perceptions and the potential for health education through this media.

TikTok and adolescent vision health: Content and information quality assessment of the top short videos related to myopia

Background

Despite the increasing recognition of the public health value of social media platforms, TikTok short videos focusing on adolescent vision health have not received much attention. We aimed to evaluate the content, sources, and information quality of myopia-related videos on TikTok.

Methods

The top 200 most-liked myopia-related videos on the Chinese version of TikTok were queried and screened on March 12, 2022. The descriptive characteristics, contents, and sources of the selected 168 videos were obtained, and their overall quality, reliability, understandability, and actionability were assessed using the validated scoring instruments DISCERN and PEMAT-A/V.

Results

Medical professionals were the main source (45.8%, 77/168) of videos. Misinformation (10.1%, 17/168) was mainly attributable to for-profit organizations (20%, 3/15) and individual non-medical users (31.3%, 10/32). However, their videos enjoyed the highest numbers of "likes," "comments," and "shares" (P < 0.05). The mean reliability and overall quality regarding treatment choice were (2.5 ± 0.5) and (3.1 ± 0.9), respectively. Videos on TikTok showed relatively high understandability (84.7%) and moderate actionability (74.9%). Video producers tended to partly or fully provide information regarding management (81.5%, 137/168) and outcome (82.1%, 138/168), and to ignore or only slightly mention content related to definition (86.9%, 146/169) and signs (82.1%, 138/168). The five video sources showed significant differences in the prevalence of misleading information (P < 0.001), publication reliability (P < 0.001), overall quality (P = 0.039), content score (P = 0.019), and understandability (P = 0.024).

Conclusion

Considering the moderate-to-poor reliability and variable quality across video sources, the substantial myopia-related content on TikTok should be treated with caution. Nevertheless, TikTok videos may serve as a surrogate or supplement for information dissemination if providers can ensure more comprehensive and accurate content.

How public health agencies communicate with the public on TikTok under the normalization of COVID-19: A case of 2022 Shanghai's outbreak

Objective

As life with COVID-19 became a norm in 2022, the public's demand for and perception of COVID-19-related information has changed. This study analyzed the performance and responses of Healthy China and the public at various stages of COVID-19 normalization using the crisis and emergency risk communication (CERC) theory.

Methods

This study was based on the 2022 Shanghai COVID-19 outbreak and data from "Healthy China," the official TikTok account of the National Health Commission of the People's Republic of China (NHCC). First, we divided the Shanghai lockdown into five stages in accordance with the CERC. Second, the videos released by Healthy China were open-coded. Third, to understand the distribution of strategies across the stages, we used counts and percentages to summarize the categorical variables. Fourth, we investigated the distribution of public participation indicators using descriptive statistical analysis. Finally, the relationship between stage and communication strategy was examined using the chi-square test and negative binomial regression.

Results

(1) Healthy China adopted a more flexible approach to communication strategies; (2) new cases per day was the commonly used substrategy for uncertainty reduction; (3) there was a significant difference in the strategies used by Healthy China at different stages; (4) public participation was highest in the pre-crisis period; and (5) the stage had a significant positive impact on the number of views, favorites, likes, and shares.

Conclusions

This research provides insight into effective communication strategies for the government or public health agencies to employ during COVID-19 normalization.

Content Analysis of Nicotine Poisoning (Nic Sick) Videos on TikTok: Retrospective Observational Infodemiology Study

Background

TikTok is a microvideo social media platform currently experiencing rapid growth and with 60% of its monthly users between the ages of 16 and 24 years. Increased exposure to e-cigarette content on social media may influence patterns of use, including the risk of overconsumption and possible nicotine poisoning, when users engage in trending challenges online. However, there is limited research assessing the characteristics of nicotine poisoning–related content posted on social media.

Objective

We aimed to assess the characteristics of content on TikTok that is associated with a popular nicotine poisoning–related hashtag.

Methods

We collected TikTok posts associated with the hashtag #nicsick, using a Python programming package (Selenium) and used an inductive coding approach to analyze video content and characteristics of interest. Videos were manually annotated to generate a codebook of the nicotine sickness–related themes. Statistical analysis was used to compare user engagement characteristics and video length in content with and without active nicotine sickness TikTok topics.

Results

A total of 132 TikTok videos associated with the hashtag #nicsick were manually coded, with 52.3% (69/132) identified as discussing firsthand and secondhand reports of suspected nicotine poisoning symptoms and experiences. More than one-third of nicotine poisoning–related content (26/69, 37.68%) portrayed active vaping by users, which included content with vaping behavior such as vaping tricks and overconsumption, and 43% (30/69) of recorded users self-reported experiencing nicotine sickness, poisoning, or adverse events such as vomiting following nicotine consumption. The average follower count of users posting content related to nicotine sickness was significantly higher than that for users posting content unrelated to nicotine sickness (W=2350.5, P=.03).

Conclusions

TikTok users openly discuss experiences, both firsthand and secondhand, with nicotine adverse events via the #nicsick hashtag including reports of overconsumption resulting in sickness. These study results suggest that there is a need to assess the utility of digital surveillance on emerging social media platforms for vaping adverse events, particularly on sites popular among youth and young adults. As vaping product use-patterns continue to evolve, digital adverse event detection likely represents an important tool to supplement traditional methods of public health surveillance (such as poison control center prevalence numbers).

Characterizing COVID-19 Content Posted to TikTok: Public Sentiment and Response During the First Phase of the COVID-19 Pandemic

PURPOSE

The purpose of this study was to characterize COVID-19 content posted by users and disseminated via TikTok, a social media platform that has become known largely as an entertainment platform for viral video-sharing. We sought to capture how TikTok videos posted during the initial months of the COVID pandemic changed over time as cases accelerated.

METHODS

This study is an observational analysis of sequential TikTok videos with #coronavirus from January to March 2020. Videos were independently coded to assess content (e.g., health relatedness, humor, fear, empathy), misinformation, and public sentiment. To assess engagement, we also codified how often videos were shared relative to their content.

RESULTS

We coded 750 videos and approximately one in four videos tagged with #coronavirus featured health-related content such as featuring objects such as face masks, hand sanitizer, and other cleaning products. Most videos evoked "humor/parody," whereas 15% and 6% evoked "fear" and "empathy", respectively. TikTok videos posted in March 2020 had the largest number of shares and comments compared with January and February 2020. The proportion of shares and comments for "misleading and incorrect information" featured in videos was lower in March than in January and February 2020. There was no statistical difference between the share and comment counts of videos coded as "incorrect/incomplete" and "correct" over the entire time period.

CONCLUSIONS

Analyzing readily available social media platforms, such as TikTok provides real-time insights into public views, frequency and types of misinformation, and norms toward COVID-19. Analyzing TikTok videos has the potential to be used to inform public health messaging and public health mitigation strategies.
