"The dream is that there's one place you go": a qualitative study of women's experiences seeking care from Long COVID clinics in the USA.

BACKGROUND: Seeking and obtaining effective health care for Long COVID remains a challenge in the USA. Women have particularly been impacted, as they are both at higher risk of developing Long COVID and of facing gendered barriers to having symptoms acknowledged. Long COVID clinics, which provide multidisciplinary and coordinated care, have emerged as a potential solution. To date, however, there has been little examination of U.S. patient experiences with Long COVID clinics and how patients may or may not have come to access care at a Long COVID clinic. METHODS: We conducted semi-structured interviews with 30 U.S. women aged 18 or older who had experienced Long COVID symptoms for at least 3 months, who had not been hospitalized for acute COVID-19, and who had seen at least one medical provider about their symptoms. Participants were asked about experiences seeking medical care for Long COVID. Long COVID clinic-related responses were analyzed using qualitative framework analysis to identify key themes in experiences with Long COVID clinics. RESULTS: Of the 30 women, 43.3% (n = 13) had been seen at a Long COVID clinic or by a provider affiliated with a Long COVID clinic and 30.0% (n = 9) had explored or attempted to see a Long COVID clinic but had not been seen at time of interview. Participants expressed five key themes concerning their experiences with seeking care from Long COVID clinics: (1) Access to clinics remains an issue, (2) Clinics are not a one stop shop, (3) Not all clinic providers have sufficient Long COVID knowledge, (4) Clinics can offer validation and care, and (5) Treatment options are critical and urgent. CONCLUSIONS: While the potential for Long COVID clinics is significant, findings indicate that ongoing barriers to care and challenges related to quality and coordination of care hamper that potential and contribute to distress among women seeking Long COVID care. Since Long COVID clinics are uniquely positioned and framed as being the place to go to manage complex symptoms, it is critical to patient wellbeing that they be properly resourced to provide a level of care that complies with emerging best practices.

Promotion of an Algorithm-Based Tool for Pregnancy Prevention by Instagram Influencers.

Objective: Despite growing concerns that some digital algorithm-reliant fertility awareness-based methods of pregnancy prevention are marketed in an inaccurate, opaque, and potentially harmful manner online, there has been limited systematic examination of such marketing practices. This article therefore provides an empirical examination of how social media influencers have promoted the fertility tracking tool Daysy on Instagram. We investigate: (1) how the tool is framed in relation to pregnancy prevention using Health Belief Model (HBM) constructs, and (2) the promotional and disclosure practices adopted by influencers. Materials and Methods: We collected Instagram posts mentioning Daysy made between June 2018 and May 2022 using the tool CrowdTangle. Using a qualitative content analysis approach, we coded a random sample of 400 Daysy posts. This yielded 122 Instagram influencer posts promoting Daysy for pregnancy prevention that we coded for promotional content and HBM constructs. Results: Posts originated primarily from Europe (n = 62, 50.82%) and the United States (n = 37, 30.33%). Findings indicate that barriers to use (n = 18, 15.57%) and the severity of risks from unplanned pregnancy (n = 8, 6.56%) were rarely conveyed, whereas benefits of use (n = 122, 100%) and the severity of risks of hormonal contraception (n = 31, 25.41%) were covered more extensively. Only about one third of posts disclosed any formal relationship to the brand Daysy. Conclusions: With many posts emphasizing benefits and obscuring potential limitations, we argue that accurate and transparent information about the effectiveness and limitations of fertility tracking technologies is critical for supporting informed decision-making and, as such, should remain a public health priority.

Tobacco, nicotine and counter-marketing promotions using Instagram's branded content tool.

BACKGROUND: The social media conglomerate, Meta, has a policy prohibiting promotion of tobacco products, vaporisers, electronic cigarettes or other products that simulate smoking via their branded content tools. This study examines if branded Instagram posts comply with these self-regulatory efforts. METHODS: We analysed the presence and content of tobacco/nicotine promotion, as well as counter-marketing, in a sample of 400 branded/paid partnership-labelled Instagram posts with tobacco/nicotine-related terms made between 31 July 2022 and 31 March 2023, gathered from Meta's CrowdTangle tool and classified by CrowdTangle as being in English. RESULTS: Of the 217 active branded posts that mentioned or depicted tobacco/nicotine products, most promoted rather than countered the sale of such products (84.3% vs 15.7%, respectively). Posts originating from US Instagram users accounted for 42.6% of promotional content. After the USA, posts from Indonesia (19.1%), Pakistan (9.8%) and India (8.2%) were most frequent. Most posts were fully in English (74.9%). Posts featured hookah (39.4%), electronic nicotine delivery systems (ENDS) accessories (17.5%), ENDS devices and e-liquids (16.9%) and various types of cigars (15.3%). The majority of US posts promoted venues or events where tobacco/nicotine products were featured (71.8%). Almost half of all promotional posts (47.0%) were sponsored by tobacco industry accounts. Posts that encouraged cessation were primarily (47.1%) sponsored by non-government organisations. CONCLUSION: Despite attempts at self-regulation, paid partnership posts promoting tobacco and nicotine products are present on Instagram, especially posts promoting venues and events that feature tobacco and nicotine use. Self-regulation of this content shows limited success, suggesting a need for federal oversight and additional counter-marketing in social media settings.

A systematic review for the impacts of global approaches to regulating electronic nicotine products.

Background: The rapid increase in electronic nicotine product (ENP) use among young people has been a global public health challenge, given the potential harm of ENPs and nicotine dependence. Many countries have recently introduced legislations to regulate ENPs, but the impacts of these policies are poorly understood. This systematic review aims to critically synthesise empirical studies on the effects of global regulations regarding ENPs on the prevalence of use, health outcomes and their determinants, using the 4A marketing mix framework (acceptability, affordability, accessibility and awareness). Methods: Following the PRISMA guideline, we searched PubMed, Embase, Scopus, Web of Science, Academic Search Complete, Business Source Complete, and APA PsycINFO databases from inception until June 14, 2022 and performed citation searches on the included studies. Reviewed literature was restricted to peer-reviewed, English-language articles. We included all pre-post and quasi-experimental studies that evaluated the impacts of e-cigarette policies on the prevalence of ENP use and other health outcomes. A modified Joanna Briggs Institute (JBI) Critical Appraisal checklist for quasi-experimental studies was used for quality assessment. Due to heterogeneity of the included studies, we conducted a narrative synthesis of evidence. Results: Of 3991 unduplicated records screened, 48 (1.2%) met the inclusion criteria, most were from high-income countries in North America and Europe and 26 studies measured self-reported ENPs use. Flavour restrictions significantly decreased youth ENP use and taxation reduced adult use; mixed results were found for the impacts of age restrictions. Indoor vaping restrictions and the European Tobacco Products Directive (TPD) did not seem to reduce ENP use based on existing studies. Changes in determinants such as sales and perceptions corroborated our conclusions. Few studies assessed the impacts of other regulations such as advertising restrictions and retail licensing requirements. Conclusions: Flavour restrictions and taxes have the strongest evidence to support effective control of ENPs, while others need powerful enforcement and meaningful penalties to ensure their effectiveness. Future research should focus on under-examined policies and differential impacts across sociodemographic characteristics and countries. Registration: PROSPERO CRD42022337361.

Oh Baby! A Content Analysis of Contraception Pins on Pinterest.

BACKGROUND: Social media platforms have become a popular source for health information despite concerns about the quality of content shared. We examined how oral contraceptive pills and intrauterine devices are framed on the platform Pinterest using the Health Belief Model (HBM), as well as how fertility awareness methods are portrayed as an alternative to hormonal contraception. METHODS: We collected pins in February 2021 using searches for birth control, oral contraceptives, and intrauterine devices. After excluding paid ads and pins not relevant to contraceptive use, we conducted a content analysis of 404 pins using a coding framework grounded in the HBM. We carried out descriptive statistics for all variables in the final sample. RESULTS: Following coding, we found that 54.7% of pins mentioned oral contraceptive pills, 41.58% mentioned intrauterine devices, and 11.63% mentioned fertility awareness methods. Fertility awareness pins had the highest percentage of benefits conveyed (70.21%), followed by intrauterine devices (44.05%), then oral contraceptive pills (38.91%). Pill pins had the highest percentage of barriers conveyed (52.94%) and fertility awareness had the least (25.53%). Side effects were the most mentioned barrier among pill (37.10%) and intrauterine device pins (23.21%). Very few pins were made by (2.48%) or originated with medical institutions (5.45%). CONCLUSIONS: Oral contraceptive pills are often negatively framed on Pinterest, whereas intrauterine devices and fertility awareness methods are more positively framed. This suggests a need for clear communication from clinicians regarding all contraceptive options and their relative merits and risks.

E-cigarette brands and social media influencers on Instagram: a social network analysis.

BACKGROUND: Exposure to visual posts featuring e-cigarette products on social media is associated with increased e-cigarette use among US adolescents. Instagram is the largest source of e-cigarette social media marketing, where influencers-for example, bloggers, brand ambassadors-post promotional materials. This study analysed the network of e-cigarette brands and influencers on Instagram, characterising the most central players in e-cigarette social media marketing. METHODS: We tracked influencers with public profiles on Instagram who posted promotional e-cigarette content in 2020, had over 1000 followers and high user engagement rate (ratio of likes and comments to followers) of 1%-25% per post. By conducting a social network analysis, we identified the most central (highly involved in promotional activities) influencers and e-cigarette brands. The number of the influencers' followers aged 13-17 years old and the age verification practices restricting youth access were also assessed. RESULTS: There is a highly interconnected network of engaging e-cigarette influencers (n=55) worldwide who collaborated with over 600 e-cigarette brands in 2020. The Asian and US influencers had five to six times more teenage followers compared with the European influencers. 75% of the influencers did not restrict youth access to their promotional content on Instagram. The brands Voopotech, Innokin, Geekvape, Lost Vape, Smok and Vaporesso collaborated with the largest number of influencers (mean n=20). CONCLUSIONS: It is important to understand associations among influencers and e-cigarette use behaviours, especially youth, to inform effective public health communication and potential policies that could regulate social media marketing sponsored by e-cigarette companies.

Tobacco promotion restriction policies on social media.

Tobacco promotion is prolific on social media, with each platform setting their own restrictions on tobacco promotion and sales. We evaluated the policies related to tobacco product promotion and sales on 11 sites that are popular with youth in May 2021: Discord, Facebook, Instagram, Pinterest, Reddit, Snapchat, TikTok, Tumblr, Twitch, Twitter and YouTube. Nine of the 11 sites prohibited paid advertising for tobacco products. However, only three of them clearly prohibited sponsored content (ie, social influencers) that promotes tobacco. Six platforms restricted content that sells tobacco products and three tried to prohibit underage access to content that promotes or sells tobacco products. Although most platform policies prohibited paid tobacco advertising, few addressed more novel strategies, such as sponsored/influencer content and few had age-gating to prevent youth access. There is a pressing need to regulate tobacco promotion on social media platforms.

Between Healthcare Practitioners and Clergy: Evangelicals and COVID-19 Vaccine Hesitancy.

Evangelical Christians are among the most hesitant to get the COVID-19 vaccine. This study examined the extent to which COVID-19 vaccination uptake among Evangelicals is explained by demographic characteristics, Health Belief Model constructs, and faith-based support factors. Survey research firm Qualtrics recruited 531 U.S. adults and conducted a survey to explore predictors of COVID-19 vaccine uptake among people who self-identified as Evangelicals in September 2021. A logistic regression showed that those reporting high perceived benefits of the COVID-19 vaccine were more likely to be vaccinated, while those reporting high perceived barriers were less likely to be vaccinated. Those whose healthcare provider asked them about the vaccine were more likely to be vaccinated than those whose healthcare provider did not ask. Finally, while those who reported information seeking from religious leaders were less likely to be vaccinated, those who reported more faith-based support for vaccination were more likely to be vaccinated. In addition to beliefs about benefits and barriers to vaccination, the role of healthcare providers and clergy were important factors influencing vaccination status. Intervention efforts that capitalize on partnerships between health providers and clergy in supportive congregations may be able to reach undecided Evangelicals.

Mental Healthcare Utilization, Modalities, and Disruptions During Spring 2021 of the COVID-19 Pandemic Among U.S. Adolescents.

PURPOSE: The COVID-19 pandemic fomented a mental health crisis among adolescents. The present study contributes a national snapshot of mental healthcare utilization, including disruptions, barriers, and modalities, among U.S. adolescents. METHODS: Logistic regressions analyzing self-reports from a representative sample (N = 532) of 13-17-year-olds recruited from the AmeriSpeak Teen Panel during Spring 2021. RESULTS: Few demographic characteristics were associated with disruptions. Text-based communication/chat was most prevalent among minoritized racial and ethnic groups. Parental support was positively associated with finding private space for telehealth visits. Black adolescents were less likely to report in-person visits. Among those unable to receive care, Black adolescents preferred in-person visits. DISCUSSION: Policies enacted to facilitate access to text-based communication/chat should continue to limit disruptions and promote racial equity. Additional efforts should target improving access to in-person visits among Black adolescents. Clinicians should encourage parent/guardian collaboration to facilitate access to private space for telehealth visits.

State Health Department Communication about Long COVID in the United States on Facebook: Risks, Prevention, and Support.

Greater public awareness of long COVID severity and susceptibility is needed to support those with long COVID and encourage preventive behaviors. It is not yet known to what extent health departments have informed the public about long COVID risks or offered guidance and support for those with long COVID. The objective of this research was to determine how and to what extent US state health departments have communicated with the public about long COVID via Facebook. Facebook posts with COVID-19 and long COVID terms made by 50 US state health departments plus Washington, DC, from 1 January 2020 to 31 January 2022, were collected using CrowdTangle. The first long COVID post appeared on 15 July 2020. From 15 July 2020 to 31 January 2022, state health departments made 49,310 COVID-19 posts and 137 long COVID posts. Using quantitative content analysis methods, long COVID posts were coded for health belief model constructs. Among long COVID posts, 75.18% included language about susceptibility, 64.96% severity, and 64.23% benefits of prevention. Cues to preventive action appeared in 54.01% of posts. 19.71% of posts provided guidance for those with long COVID. While health departments posted extensively about COVID-19, posts about long COVID were rare. This represents a missed opportunity to bolster arguments for preventive behaviors and support those experiencing long COVID.

A Multi-Site Analysis of the Prevalence of Food Insecurity in the United States, before and during the COVID-19 Pandemic.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic profoundly affected food systems including food security. Understanding how the COVID-19 pandemic impacted food security is important to provide support and identify long-term impacts and needs. OBJECTIVE: The National Food Access and COVID research Team (NFACT) was formed to assess food security over different US study sites throughout the pandemic, using common instruments and measurements. This study presents results from 18 study sites across 15 states and nationally over the first year of the COVID-19 pandemic. METHODS: A validated survey instrument was developed and implemented in whole or part through an online survey of adults across the sites throughout the first year of the pandemic, representing 22 separate surveys. Sampling methods for each study site were convenience, representative, or high-risk targeted. Food security was measured using the USDA 6-item module. Food security prevalence was analyzed using ANOVA by sampling method to assess statistically significant differences. RESULTS: Respondents (n = 27,168) indicate higher prevalence of food insecurity (low or very low food security) since the COVID-19 pandemic, compared with before the pandemic. In nearly all study sites, there is a higher prevalence of food insecurity among Black, Indigenous, and People of Color (BIPOC), households with children, and those with job disruptions. The findings demonstrate lingering food insecurity, with high prevalence over time in sites with repeat cross-sectional surveys. There are no statistically significant differences between convenience and representative surveys, but a statistically higher prevalence of food insecurity among high-risk compared with convenience surveys. CONCLUSIONS: This comprehensive study demonstrates a higher prevalence of food insecurity in the first year of the COVID-19 pandemic. These impacts were prevalent for certain demographic groups, and most pronounced for surveys targeting high-risk populations. Results especially document the continued high levels of food insecurity, as well as the variability in estimates due to the survey implementation method.

Seeking Help From Trusted Adults in Response to Peers' Social Media Posts About Mental Health Struggles: Qualitative Interview Study Among Latinx Adolescents.

BACKGROUND: Rather than confiding in adults about their mental health struggles, adolescents may use social media to disclose them to peers. Disclosure recipients are tasked with deciding whether to alert an adult and, if so, whom to alert. Few studies have examined how adolescents decide on a trusted adult to help a friend who posts on social media about his/her mental health struggles. Moreover, Latinx adolescents are underrepresented in research on social media use, which creates gaps in understanding how social media may influence their well-being. OBJECTIVE: This qualitative study presents findings from semistructured interviews with Latinx adolescents to investigate how they seek out trusted adults when a friend posts on social media about their mental health struggles. Specifically, we sought to determine which adult ties they activated, the resources they believed the adult could provide, and the support they expected the adult to provide. METHODS: We recruited participants through a nonprofit organization serving the Latinx community (primarily of Mexican origin) located in Milwaukee, Wisconsin. We conducted 43 semistructured interviews, each lasting 60-90 minutes, with Latinx adolescents (25 females, 18 males) aged 13-17 years. All interviews were conducted in English, at the adolescents' request. Using a grounded theory approach, we identified the nature of the relationship between the trusted adult and either the disclosure recipient or distressed friend, and the resources and support the trusted adult is expected to provide. RESULTS: Participants nominated adults who were emotionally or physically proximate to either the disclosure recipient or distressed friend, particularly parents (of the recipient and friend) and school staff. However, some felt that not all parents and school staff were emotionally proximate. Adolescents sought trusted adults with access to two resources: experiential knowledge and authority. Some, particularly males, avoided adults with authority because of the risk of punishment and others thought their immigrant parents did not have relevant experiential knowledge to assist them. Interviewees felt that trusted adults with either resource could provide emotional and instrumental support either directly or indirectly, while those with experiential knowledge could provide informational support. Notably, interviews did not problematize the fact that the disclosure occurred on social media when deliberating about adults. CONCLUSIONS: To assist a distressed friend posting on social media, Latinx adolescents look not only for trusted adults who are emotionally and physically proximate but also those who have key resources that facilitate support. Efforts should focus on connecting adolescents with trusted adults and training adults who hold positions of authority or experiential knowledge to offer both direct and indirect support. Additionally, efforts should consider how immigrant experiences shape parent-child relations and address the potential long-term consequences of oversurveillance of Latinx youth, particularly males, by school staff for their access to social support.

Perceptions of Alerts Issued by Social Media Platforms in Response to Self-injury Posts Among Latinx Adolescents: Qualitative Analysis.

BACKGROUND: There is growing interest in using social media data to detect and address nonsuicidal self-injury (NSSI) among adolescents. Adolescents often do not seek clinical help for NSSI and may adopt strategies to obscure detection; therefore, social media platforms may be able to facilitate early detection and treatment by using machine learning models to screen posts for harmful content and subsequently alert adults. However, such efforts have raised privacy and ethical concerns among health researchers. Little is currently known about how adolescents perceive these efforts. OBJECTIVE: The aim of this study is to examine perceptions of automated alerts for NSSI posts on social media among Latinx adolescents, who are at risk for NSSI yet are underrepresented in both NSSI and health informatics research. In addition, we considered their perspectives on preferred recipients of automated alerts. METHODS: We conducted semistructured, qualitative interviews with 42 Latinx adolescents between the ages of 13 and 17 years who were recruited from a nonprofit organization serving the Latinx community in Milwaukee, Wisconsin. The Latinx population in Milwaukee is largely of Mexican descent. All interviews were conducted between June and July 2019. Transcripts were analyzed using framework analysis to discern their perceptions of automated alerts sent by social media platforms and potential alert recipients. RESULTS: Participants felt that automated alerts would make adolescents safer and expedite aid before the situation escalated. However, some worried that hyperbolic statements would generate false alerts and instigate conflicts. Interviews revealed strong opinions about ideal alert recipients. Parents were most commonly endorsed, but support was conditional on perceptions that the parent would respond appropriately. Emergency services were judged as safer but inappropriate for situations considered lower risk. Alerts sent to school staff generated the strongest privacy concerns. Altogether, the preferred alert recipients varied by individual adolescents and perceived risks in the situation. None raised ethical concerns about the collection, analysis, or storage of personal information regarding their mental health status. CONCLUSIONS: Overall, Latinx adolescents expressed broad support for automated alerts for NSSI on social media, which indicates opportunities to address NSSI. However, these efforts should be co-constructed with adolescents to ensure that preferences and needs are met, as well as embedded within broader approaches for addressing structural and cultural barriers to care.

U.S. public support for COVID-19 vaccine donation to low- and middle-income countries during the COVID-19 pandemic.

As COVID-19 vaccines become available to the public, there will be a massive worldwide distribution effort. Vaccine distribution has historically been unequal primarily due to the inability of nations with developing economies to purchase enough vaccine to fully vaccinate their populations. Inequitable access to COVID-19 vaccines will not just cause humanitarian suffering, it will likely also be associated with increased economic suffering worldwide. This study focuses on the U.S. population and its beliefs about future COVID-19 vaccine donation by the U.S. to low- and middle-income countries. This study carried out a survey among 788 U.S. adults. Variables include demographics, COVID-19 vaccine priority status, COVID-19 vaccine donation beliefs, and Social Dominance Orientation. Analyses showed that older respondents were both less likely to endorse higher levels of COVID-19 vaccine donations and were more likely to want to wait until all in the U.S. who want the vaccine have received it; those who identified as Democrats were more likely to endorse higher levels of future COVID-19 vaccine donation than Republicans; and those scoring higher on SDO were both less likely to endorse higher levels of COVID-19 vaccine donations as well as more likely to want to wait until all in the U.S. who want the vaccine have received it. Policymakers, as well as healthcare providers and public health communication professionals, should give consideration to those messages most likely to engender support for global prevention efforts with each audience segment.

Content Analysis of U.S. Newspaper Coverage of Causes and Solutions to Vaping-Associated Lung Injury.

BACKGROUND: In 2019, an outbreak of vaping-associated lung injury (also known as "EVALI") spread throughout the U.S., linked to use of illicit THC cartridges. This paper examines U.S. newspaper coverage on the causes and solutions to EVALI. Methods: A content analysis of 417 articles from April to December 2019 from two national newspapers, one regional newspaper, and the Associated Press was conducted. Articles were coded for information about EVALI causes, mentions of the brand Dank Vapes, calls for individuals take a specific action to prevent harm, and mentions of policy actions to address vaping. Mentions of increasing youth vaping and JUUL were also coded. Results: Most articles (77%) provided an update on the number of EVALI cases and/or deaths. Fewer described EVALI symptoms (20%) or mentioned vaping cessation resources available to the public (2%). Almost half of articles also mentioned youth vaping as a concern (49%). Dank Vapes was mentioned rarely (4%) compared to JUUL (39%). After CDC recommendations changed to no longer recommend avoiding all vaping products, news articles became significantly less likely to mention nicotine products as a cause of EVALI or suggest that individuals cease all vaping. While policy was generally not articulated as a solution to EVALI, banning or limiting flavored nicotine vaping products were the most common policy actions mentioned. Conclusions/Importance: The discussions of causes of and solutions to EVALI were often intertwined with coverage of youth vaping, potentially failing to convey a clear sense of how the public should respond to the EVALI outbreak.

Willingness to get the COVID-19 vaccine with and without emergency use authorization.

BACKGROUND: This study assessed psychosocial predictors of U.S. adults' willingness to get a future COVID-19 vaccine and whether these predictors differ under an emergency use authorization (EUA) release of the vaccine. METHODS: A survey of 788 U.S. adults was conducted to explore the relationships between demographics and psychosocial predictors of intent to get a future COVID-19 vaccine as well as willingness to get such a vaccine under EUA. RESULTS: Significant predictors of COVID-19 vaccine uptake intentions were education, having insurance, scoring high on subjective norms, a positive attitude toward the vaccine, as well as high perceived susceptibility to COVID-19, high perceived benefits of the vaccine, scoring low on barriers to the vaccine, and scoring high on self-efficacy. Predictors of willingness to take a COVID-19 vaccine under EUA were age, race/ethnicity, positive subjective norms, high perceived behavioral control, positive attitudes toward the vaccine, as well as high perceived susceptibility to COVID-19, high perceived benefits of the vaccine, low barriers to the vaccine, and scoring high on self-efficacy for getting the vaccine. Concerns about rushed vaccine development appear to reduce vaccine uptake intent, as well as willingness to get the vaccine under EUA. CONCLUSIONS: COVID-19 vaccine-related messages should both address concerns about the vaccine and its development and reinforce benefits of the vaccine (both factors significant in both models). Vaccine efforts may need to go beyond just communications campaigns correcting misinformation about a COVID-19 vaccine to also focus on re-establishing public trust in government agencies.

Social media's influence on e-cigarette use onset and escalation among young adults: What beliefs mediate the effects?

As an extension of a previous cross-sectional study, this study employed prospective data to test positive outcome expectancy beliefs as mediators of social media's influence on e-cigarette use progression among young adults. Self-report data were collected from 2327 young adult college students (Mean age = 21.2; SD = 2.1; 54% women) between 2017 and 2019, every 6-month, at 3 time-points. Structural equation modeling was used to test the mediational models. Among baseline never e-cigarette users, higher affect regulation expectancies-e.g., beliefs that e-cigarette use results in feeling good, reduced boredom and stress-mediated the effects of higher baseline social media e-cigarette exposure on e-cigarette use onset one year later. Among baseline lifetime e-cigarette users, higher positive sensory, positive "smoking" experience, and affect regulation expectancy beliefs mediated the effects of higher social media e-cigarette exposure at baseline on increased current e-cigarette use one year later. E-cigarette content on social media may persuade young adults to try e-cigarettes by imparting the sense that e-cigarettes make one feel good and help reduce stress. E-cigarette content on social media that promote e-cigarette flavors and e-cigarettes as cleaner and a socially more acceptable alternative to cigarettes may work to escalate e-cigarette use among experimenters. Efforts to prevent e-cigarette use onset and escalation may need to target the outcome expectancy beliefs influenced by social media.

HPV Vaccine Searches on Pinterest: Before and After Pinterest's Actions to Moderate Content.

Objectives. To compare how human papillomavirus (HPV) vaccination was portrayed on Pinterest before and after the platform acted to moderate vaccine-related search results to understand (1) what the information environment looked like previously and (2) whether Pinterest's policy decisions improved this environment in terms of sources and content.Methods. In this quantitative content analysis, we compared 2 samples of 500 HPV vaccine-focused Pinterest posts ("pins") collected before and after Pinterest's actions to provide more reliable vaccine-related information. Pins were based on search results and were analyzed using the Health Belief Model.Results. The majority of preaction search results leaned toward vaccine skepticism, specifically focused on perceived vaccine barriers. Few pins were published by public health-related Pinterest accounts. Postaction search results showed a significant shift to HPV vaccination benefits, and the number of pins by government or medical accounts increased. However, the proportion of pins in search results containing HPV content of any type was significantly lower.Conclusions. Pinterest's efforts to moderate vaccination discussions were largely successful. However, the ban also appeared to limit HPV vaccination search results overall, which may contribute to confusion or an information vacuum.

Young Adult Identification and Perception of Hashtag-Based Vaping Claims on Instagram.

Social media platforms are home to large volumes of ambiguous hashtag-based claims about the health, modified-risk, and cessation benefits of electronic cigarette products (e.g., #Vapingsavedmylife). The objective of this study was to qualitatively explore how young adults interpret these hashtags on the popular platform Instagram. Specifically, we sought to identify if they view these hashtags as making health-related claims, and if they find these claims to be credible and valid. We conducted 12 focus groups in 2018 with non-tobacco users, smokers, dual users, and vapers between the ages of 18 and 24 (n = 69). Using real Instagram posts to guide discussion, participants reflected on the meaning of potentially claims-making hashtags. Participants interpreted the majority of the hashtags as making health-related claims. However, many participants felt that the claims were too exaggerated to be entirely valid. Some participants, including dual users and vapers, argued that smoking and vaping were largely equivalent. Smokers were particularly skeptical of claims. Findings suggest that the U. S. Food and Drug Administration should consider hashtag-based claims in their regulatory efforts. However, further research is needed on how to pragmatically address claims taking the form of hashtags given legal and practical constraints.
