From tragedy to advocacy: How celebrity suicides transform mental health conversations on Facebook
Understanding the dynamics of social media discourse is critical for advancing mental health advocacy and support. While prior research has examined increases in online search activity following celebrity suicides, little is known about how mental health conversations evolve on social media in response to these events. This study addresses that gap by analysing shifts in public discourse on Facebook before and after the suicides of four high-prof…
Synthetic News, Natural Doubts? A Meta-Analysis of Credibility Perceptions of AI-Generated News
As generative artificial intelligence (AI) becomes increasingly integrated into news production, concerns about the credibility of synthetic news content are intensifying. While some studies report that audiences find AI-generated news less credible than human-written content, others reveal mixed or even reversed findings. This meta-analysis synthesizes findings across 31 studies (41 effect sizes) to assess how the source label (AI vs. human) inf…
Association of Vaping Reasons with Stress, Anxiety, and Depression Among Young Adults Who Currently Vape
Purpose: The use of e-cigarettes can worsen mental health symptoms in young adults. However, little is known about how young adults’ mental health may relate to their reasons for using e-cigarettes (vaping). We examined the association of mental health and vaping reasons among young adults who currently vape. Methods: Data were analyzed from a sample of young adults who vape (N = 436, Mage=25.19) who participated in an online survey assessing men…
Large language models' varying accuracy in recognizing risk-promoting and health-supporting sentiments in public health discourse: The cases of HPV vaccination and heated tobacco products
Moral Foundations, Ideological Divide, and Public Engagement with U.S. Government Agencies’ Covid-19 Vaccine Communication on Social Media
Guided by moral foundation theory, this study examined how moral framing interacted with local constituents' ideological leaning to affect public engagement outcomes of government agencies' COVID-19 vaccine communication on Facebook. We analyzed a dataset of over 5,000 U.S. government agencies' Facebook posts on COVID-19 vaccines in 2021 (N = 70,671), assessed their use of moral language using a newly developed computational method, and examined …
Leveraging social media to enhance celebrity stories for anti-stigma efforts
Moralization of E-cigarette Use and Regulation: A Mixed-Method Computational Analysis of Opinion Polarization
E-cigarette use, or vaping, is undergoing a process of moralization in which issues about vaping evolve from being morally neutral to having discernible moral implications. Using Moral Foundations Theory, this study compared the moral narratives underlying polarized views about e-cigarette use and regulation. We integrated computational and human strategies by conducting the Chow test on the time series data and classification, topic modeling, an…
How Public Health Agencies Break through Covid-19 Conversations: A Strategic Network Approach to Public Engagement
In times of public health emergencies, health agencies need to engage and communicate with the public in real-time to share updates and accurate information. This is especially the case for the COVID-19 pandemic where public engagement can potentially save lives and flatten the curve. This paper considers how the use of interactive features and strategic network positions of health agencies on social media influenced their public engagement outco…
Testing the Effectiveness of Message Framing and Episodic Future Thinking in Promoting HPV Vaccination via Anticipated Regret
One of the greatest challenges in health communication is to persuade people to enact behavior whose consequences lie in the distant future. Could the persuasiveness of a health message be increased by highlighting future regret that one may experience? Using a 2 (framing: gain vs. loss) x 3 (temporal thinking: future-thinking vs. past-thinking vs. no-thinking) factorial design, this study tested the relative effectiveness of message framing and …
Who Says What in Which Networks: What influences Social Media Users’ Emotional Reactions to the Covid-19 Vaccine Infodemic
This study aims to identify effective predictors that influence publics’ emotional reactions to COVID-19 vaccine misinformation as well as corrective messages. We collected a large sample of COVID-19 vaccine related misinformation and corrective messages on Facebook as well as the users’ emotional reactions (i.e., emojis) to these messages. Focusing on three clusters of features such as messages’ linguistic features, source characteristics, and m…
What do others’ reactions to body posting on Instagram tell us? The effects of social media comments on viewers’ body image perception
Studies have highlighted the influence of social media comments on users’ perceptual consequences, but whether this holds true in the body image context is still largely unknown. This experimental study investigated the effects of social media comments on ideal body perception and how it influences one’s own body satisfaction. Results showed that comments guided the viewers’ perceptions of what is considered as “ideal” body. Viewers of favorable …
P1-439 Effect of regular exercise on the nitric oxide levels in saliva
Introduction Nitric oxide (NO) regulates blood flow and both muscle contraction and metabolism during exercise. The plasma levels of NO increase after exercise. However, studies that determined the association between the levels of salivary NO and regular exercise are also lacking. The aim of this study was to assess the relationship of the levels of salivary NO with physical activity among Korean elderly. Methods 176 subjects aged 48–84 years ol…
Daeganghwal-tang inhibits the stem cell factor-induced migration and inflammatory cytokines secretion in mast cells
Traditional Oriental medicinal prescription, Daeganghwal-tang (DGHT) has been used for the treatment of rheumatoid arthritis (RA) in Korea. However, its effect in experimental models remains unknown. Recent reports suggest that in patients with RA, synovial mast cells increase in number and show signs of activation and inflammatory cytokines secretion. Our results show that stem cell factor (SCF) is a potent chemotactic factor for the mast cells …
