However, the diverse and often unverified nature of the content on social media can make it challenging to discern accurate information, contributing to user uncertainty, which may in turn contribute to low vaccination rates in some regions. This is especially true in Louisiana as its COVID-19 vaccination rates were among the lowest in the country in 2022. Therefore, understanding public sentiment on social media and developing targeted campaigns to counter unverified information is essential for advancing public health campaigns.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;The goal was to gain insights into the underlying factors that contribute to Louisiana's low vaccination rates for routine immunizations by (1) performing social media listening to develop an infodemic management plan and (2) promoting accurate information via a social media campaign.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Social media listening was conducted using Meltwater, a media monitoring and social media listening platform, supplemented by Google Alerts and Google News to identify if vaccine-related stories or sentiments were attracting unusual attention. Additionally, a social media campaign aimed at educating Louisiana residents about disease manifestation, symptoms, vaccines available for disease prevention, and potential side effects was developed. Posts were published 2 to 3 times a week and boosted for 7 days.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;From November 13, 2023, to June 11, 2024, social media listening identified at least 15 unique, noteworthy stories that signified sentiment spikes. These conversations were predominantly related to vaccine hesitancy, with users expressing opposition to vaccines or reluctance to engaging with vaccine-related information. Sentiment spikes included themes related to mistrust of vaccines and concerns about their safety and efficacy. The social media campaign received 69,600 impressions, reached 43,429 users, and received 652 reactions and likes, 62 shares, and 105 comments. Most of the audience was female, with higher engagement from older users on Facebook and younger users on Instagram. Finally, posts related to hepatitis B, rotavirus, and measles, mumps, and rubella vaccines received the most attention.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Social media has become a key tool for digital health, helping to implement disease prevention programs and promoting advances in medicine. However, unverified information remains a major reason for the aversion to vaccination despite the dissemination of information from reputable public health organizations, health professionals, hospitals, and medical centers.

Masculine norms that link emotional restraint with strength can discourage help-seeking and vulnerability. Anonymous digital spaces such as Reddit (Reddit Inc) and YouTube (Google LLC) have become informal support environments where men share experiences and emotions outside traditional constraints. Understanding these interactions offers insight into masculine identity and help-seeking behavior.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;This study examines how men discuss and negotiate mental health within anonymous online communities. It explores whether these spaces support emotional openness, peer validation, and challenges to hegemonic masculinity norms. It triangulates digital discourse with survey and interview data to assess how these patterns align with men's lived experiences and perceived barriers to support.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This cross-sectional, exploratory mixed methods study analyzed publicly available online discourse from Reddit (n=740 posts) and YouTube (n=6287 comments). The qualitative component included 23 adult men (aged 18-55 years, predominantly Asian and employed) recruited via LinkedIn (Microsoft) who completed an anonymous online survey. Of these, 9 volunteered for follow-up semistructured interviews. Data underwent computational text mining using the Natural Language Toolkit and National Research Council Lexicon for word frequency and emotion analysis, followed by Braun and Clarke's 6-phase reflexive thematic analysis. Online discourse patterns were then compared with survey and interview data. Theoretical frameworks included hegemonic masculinity, toxic positivity, and peer-support theory.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Four themes emerged across the datasets: (1) normalizing emotional expression, (2) mutual validation and peer support, (3) coping through humor and irony, and (4) pushback against toxic positivity and societal norms. Emotion analysis showed prominent expressions of sadness, fear, trust, and anger across the Reddit and YouTube corpus. Survey data showed that 20 of 23 (87%) respondents reported having no safe offline space to discuss mental health. Interview participants (n=9) largely confirmed digital discourse themes, though some divergence emerged regarding whether humor functioned as deflection or connection.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;This study combines large-scale analysis of online discourse with qualitative triangulation across Reddit, YouTube, surveys, and interviews. Theoretically, it extends inclusive masculinity theory into anonymous online contexts, showing how digital platforms enable men to negotiate emotional expression outside traditional masculine constraints.

While such visibility can raise awareness, reduce stigma, and make young people feel more connected and understood in their experiences, concerns have been raised about the diagnostic accuracy of this content, which is often produced by nonprofessionals and presented using emotionally appealing stylistic features. Although prior research has examined mental health content on TikTok broadly, little is known about how depression-related symptoms are portrayed by creators on the platform.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;Given depression's rising prevalence among youth and its prominent presence on TikTok, this study examined (1) the diagnostic accuracy of TikTok videos about depression, (2) differences in diagnostic accuracy and stylistic features by creator type (medical professionals vs nonprofessionals), and (3) how diagnostic accuracy, stylistic features (personal experiences, emotional appeals, and background music), and creator type relate to user engagement.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A quantitative content analysis was conducted of 210 English-language TikTok videos retrieved using symptom-focused search terms (eg, \"depression symptoms\"). Videos were coded for diagnostic accuracy using a standardized coding scheme based on the International Classification of Diseases, 11th Revision diagnostic criteria for depressive episodes. In addition, videos were coded for creator type, presentation style, and the presence of emotionally appealing stylistic features. Engagement was operationalized as the sum of a video's likes, comments, saves, and shares. Intercoder reliability was assessed using Krippendorff α, percent agreement, and Gwet AC1 (agreement coefficient 1). Analyses included Mann-Whitney U tests, chi-square tests, and hierarchical regression.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Diagnostic accuracy was low overall (mean score 1.21, SD 1.04, on a 0-4 scale) and did not differ significantly between medical professionals and nonprofessionals (median 1.40 [IQR 1-2] vs 1.11 [IQR 0-2]; P=.06). Hierarchical regression analysis showed that diagnostic accuracy did not predict engagement (B=-0.10; P=.19). In contrast, engagement was higher for videos containing personal experiences (B=0.41; P=.02), emotional appeals (B=0.73; P=.001), and background music (B=0.54; P=.01). Across regression models, direct-to-camera formats (Bs -0.49 to -0.69; .003≤P≤.04) and text-centered videos (Bs -0.56 to -0.64; .002≤P&lt;.01) were associated with lower engagement.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Depression-related content on TikTok is characterized by limited diagnostic completeness, regardless of creator type.

The dataset included posts in both English and Spanish. Machine learning algorithms were then applied to classify post content into predefined categories, including volume of posts, engagement, personal experiences, trivialization, perceived causes, and perceived treatability. Parametric and nonparametric tests were used to assess for differences by language. Descriptive statistics were presented using tables and graphical representations.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 852,990 posts were analyzed, including 511,510 (59.97%) in English and 341,480 (40.03%) in Spanish.

Asymptomatic conditions such as prediabetes and hypertension create a unique vulnerability to digital health misinformation, particularly on platforms where inaccurate content is prevalent. Conventional clinical responses, which often just warn patients about online misinformation, fail to address the underlying drivers of this behavior. This viewpoint proposes a novel disease characteristic-based vulnerability framework to understand this challenge, grounded in established behavioral science theories such as the capability, opportunity, and motivation-behavior model; temporal discounting; and the concept of information voids in infodemiology. We identify a critical \"information void\" for asymptomatic conditions managed primarily through lifestyle modification. This void, created by the absence of symptomatic feedback combined with delayed clinical biomarker feedback, compels patients to seek information online. Instead of viewing this information seeking as a problematic deviation, we reframe it as a \"digital phenotype\" indicating a patient's readiness for behavior change. Through case studies illustrating how this framework applies to specific conditions (prediabetes, nonalcoholic fatty liver disease, and untreated hypertension), we demonstrate its practical utility for clinicians, health systems, and policymakers. Evidence supports a multipronged approach: integrating digital health literacy into clinical encounters, providing curated evidence-based resources, and pursuing strategic institutional engagement in digital spaces. While acknowledging the framework's deliberate simplification and the need for culturally sensitive adaptation across diverse health care settings, this viewpoint offers a generalizable strategy for engaging with patients' information needs, helping transform a public health challenge into an opportunity for empowerment.</p>","PeriodicalId":73554,"journal":{"name":"JMIR infodemiology","volume":"6 ","pages":"e86489"},"PeriodicalIF":2.3,"publicationDate":"2026-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13055946/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147635221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
