“We rely on each other”: A qualitative exploration of rural Eastern Region Native American experiences during the COVID-19 pandemic

BackgroundNative American communities suffered disproportionately negative effects during the COVID-19 pandemic, yet no research has explored the experiences of rural Eastern Region Native Americans. MethodsInformed by the Native Reliance Model and Indigenous Standpoint Theory, we conducted a qualitative descriptive project in the Spring and Summer of 2022; data included semi-structured interviews and focus groups with 24 individuals representing five South Carolina tribal groups. FindingsThematic analysis yielded four emergent themes: 1) “Let's just finish the Indians off”: Pandemic distrust rooted in historical and contemporary Native American experiences; 2) “We have been misled”: Making sense of conflicting public health information; 3) “I'm not giving it to some innocent person”: COVID-19 mitigation behaviors as Native American cultural practice; and 4) “We put the plan in place”: Self-advocacy and action as a source of Native American pride and responsibility. InterpretationThese participants demonstrated resiliency grounded in family and tribal ties, even in the face of personal losses, economic struggles, and healthcare barriers. To strike a balance between cultural traditions and public health recommendations, public health practitioners should 1) build partnerships with community leaders, elders, and tribal health authorities to facilitate the development of culturally respectful interventions that address specific health concerns in the context of historical traumas; and 2) implement alternative methods of communication and engagement to ensure equitable access to healthcare services in rural locations, such as collaborating with community organizations, deploying mobile health units, and utilizing traditional channels of communication within these communities.

Supporting Local Public Health and Planning Professionals to Implement Built Environment Changes: A Technical Assistance Program to Promote Physical Activity in Texas.

Built environment approaches that improve active transportation infrastructure and environmental design can increase physical activity. Funded by the Centers for Disease Control and Prevention, the Texas Department of State Health Services rejuvenated the Texas Plan4Health program from 2018 to 2023 to expand such approaches in Texas by providing technical assistance to teams of local public health professionals and planners to identify and implement projects connecting people to everyday destinations via active transport in their communities. However, the COVID-19 pandemic prompted Texas Plan4Health to modify the delivery of technical assistance to accommodate restrictions on travel and in-person gatherings. We used qualitative methods to conduct a postintervention process evaluation to describe the modified technical assistance process, understand the experiences of the 4 participating communities, and identify short-term outcomes and lessons learned. Texas Plan4Health helped communities overcome common barriers to built environment change, facilitated collaboration across community public health and planning professionals, and educated professionals about active transportation infrastructure and the relationship between their disciplines, thereby increasing community capacity to implement built environment improvements. This outcome, however, was mediated by the pre-existing resources and previous experiences with active transportation planning among the participating communities. Public health practitioners seeking to improve active transportation infrastructure and environmental design for physical activity should consider community-engaged approaches that advance partnership-building and collaborative experiential education among public health, planning, and other local government representatives, directing particular attention and additional training toward communities with fewer resources.

Development of A Rural-Urban Classification System for Public Health Research that Accommodates Structural Differences Between States.

Rural environments in the United States present challenges to wellness, but there is a lack of tools to categorize rurality at the subcounty level. The most common tool, the FDA's 2010 RUCA codes, uses data that are over a decade old and cannot accommodate regional differences in rurality. The purpose of this study was to develop a census-tract classification system of rurality and demonstrate its use in describing HIV outcomes. We transformed census-tract measures (population density, natural resource workforce, walkability index, household type, and air quality) into local scales of rurality using factor analysis. We surveyed public health practitioners to determine cut-points and compared the resulting categorization to RUCA codes. We described the incidence of HIV in WA by rural category. Our classification system categorized 25% of census tracts as rural, 19% as periurban and 56% as urban. Our survey yielded cut-offs that were more conservative in categorizing areas urban than RUCA codes. The rate of HIV diagnosis was substantially higher in urban areas. Our rural-urban classification system offers an alternative to RUCA codes that is more responsive to regional differences.

Integrating HIV Cluster Analysis in Everyday Public Health Practice: Lessons Learned From a Public Health--Academic Partnership.

The use of molecular HIV cluster analysis to supplement public health contact tracing has shown promise in addressing HIV outbreaks. However, the potential of HIV cluster analysis as an adjunct to daily, person-by-person HIV prevention efforts remains unknown. We documented lessons learned within a unique public health-academic partnership while guiding workaday HIV prevention efforts with near-real-time molecular cluster analysis. A public health-academic partnership in the State of Rhode Island, the United States. We recorded perceptions of our team of academicians and public health practitioners that were encountered in an 18-month study evaluating the integration of molecular cluster analysis with HIV contact tracing for public health benefit. The focus was on monthly conferences where molecular clustering of each new statewide diagnosis was discussed to facilitate targeted interventions and on attempted reinterviews of all newly HIV-diagnosed persons statewide whose HIV sequences clustered to increase partner naming. Three main themes emerged: First, multidisciplinary conferences are substantially beneficial for gleaning actionable inferences from integrating molecular cluster analysis and public health data. Second, universal reinterviews were perceived to potentially have negative consequences but may be selectively beneficial. Third, the translation of cluster analysis into public health action is hampered by jurisdictional surveillance boundaries and within-jurisdictional data silos, across which data sharing is problematic. Insights from a statewide public health-academic partnership support integration of molecular HIV cluster analyses with public health efforts, which can guide public health activities to prevent transmission while identifying substantial barriers to integration, informing continued research.

Water Sanitation Quality Assessment for Hand-Dug Wells

Purpose: Public toilet sanitation facilities need to be analyzed for water sanitation quality. This research aims to explain the benefits of hand-well water for sanitation in densely populated communal environments. Theoretical framework: This article presents literature support regarding sanitation, water quality, and pollutant index in Indonesia, regarding water sanitation conditions in dense urban organizations. Method: Comprehensive data on the quality of water sanitation used by people in dense settlements. Data was collected in the form of water as a laboratory test from 24 random dug wells in four sub-districts in Bandung City and analyzed by the regulations of the Minister of Health of the Republic of Indonesia. Results and Discussion: The research results show that an average of 75% of air wells are contaminated based on water sanitation quality and pollutant index based on Minister of Health Regulation Number 32 of 2017 and Number 2 of 2023 concerning Indonesian Environmental Health and Water Health Quality Standards. Research Implications: Our findings are important for policymakers, health workers, public health practitioners, and so that the community provides public toilet facilities that can be monitored and receive government attention to improve their quality. Originality/Value: The novelty of this research lies in that it presents a comprehensive assessment of water quality indices and physical, chemical, and microbiological parameters of hand wells in dense urban organizations.

Acceptability and feasibility of tests for infection, serological testing, and photography to define need for interventions against trachoma.

Trachoma causes blindness due to repeated conjunctival infection by Chlamydia trachomatis (Ct). Transmission intensity is estimated, for programmatic decision-making, by prevalence of the clinical sign trachomatous inflammation-follicular (TF) in children aged 1-9 years. Research into complementary indicators to field-graded TF includes work on conjunctival photography, tests for ocular Ct infection, and serology. The perceived acceptability and feasibility of these indicators among a variety of stakeholders is unknown. Focus group discussions (FGDs) with community members and in-depth interviews (IDIs) with public health practitioners in Tanzania were conducted. FGDs explored themes including participants' experience with, and thoughts about, different diagnostic approaches. The framework method for content analysis was used. IDIs yielded lists of perceived strengths of, and barriers to, implementation for programmatic use of each indicator. These were used to form an online quantitative survey on complementary indicators distributed to global stakeholders via meetings, mailing lists, and social media posts. Sixteen FGDs and 11 IDIs were conducted in October-November 2022. In general, all proposed sample methods were deemed acceptable by community members. Common themes included not wanting undue discomfort and a preference for tests perceived as accurate. Health workers noted the importance of community education for some sample types. The online survey was conducted in April-May 2023 with 98 starting the questionnaire and 81 completing it. Regarding barriers to implementing diagnostics, the highest agreement items related to feasibility, rather than acceptability. No evidence of significant differences was found in responses pertaining to community acceptability based on participant characteristics. All of the indicators included were generally deemed acceptable by all stakeholders in Tanzania, although community education around the benefits and risks of different sample types, as well as addressing issues around feasibility, will be key to successful, sustainable integration of these indicators into trachoma programs.

Public awareness and concern about harmful algal blooms – United States, 2020

ABSTRACT Harmful algal blooms can cause human and animal illnesses, environmental damage, and socioeconomic impacts. We analyzed data from the first nationally representative survey to estimate public awareness and concerns about the health impacts of harmful algal blooms. Porter Novelli's Fall 2020 ConsumerStyles survey was sent to 4,548 U.S. adults between September 24 and October 10, 2020, with an overall response of 3,625 adults (80%). Weighted descriptive analyses found that over half (59%) of respondents were aware that harmful algal blooms can be a health threat, while almost a third (32%) were concerned about health or economic impacts. Awareness and concern varied by demographic characteristics. Those who reported awareness of at least one health impact were more likely to be older, White, non-Hispanic, have higher income and education levels, and not have a child in the household. Concern about harmful algal bloom impacts was lowest among males, Mountain region and inland state residents, those with higher income and education levels, and those who identify as White and non-Hispanic. Public health practitioners can improve outreach about harmful algal blooms by using information about public awareness and concerns to tailor messages for different audiences.

Viburnum: an overview in relation to risks of allergy

The genus _Viburnum_ L. (Adoxaceae, formally classified as Caprifoliaceae), contains approximately 163 species of high ecological value, distributed in the temperate and subtropical regions of the Northern Hemisphere and extending to the mountains of South America and Asia. Some species have been considered for contact sensitivity and the pollen allergenicity. The literature shows that some species can give contact hypersensitivity and _V. opulus_ can determine pollen allergy. The pratical implications of this research are destined to the public health practitioners and policymakers, the green desiners, and the public administrations: in fact, the specific knowledgements of the use of _Viburnum_ species in gardening can help to deduce some important considerations about the right destinations of the plants. In particular, in the case of school gardens, children’s green areas or sport areas, some species, as _V. opulus_, _V.plicatum, V. tinus, V. rhytidophyllum,_ wich cause dermatitis in the case of contact, should be avoid.

Zika Virus Infection Knowledge and Communication Preferences Among Women of Reproductive Age in Central Brooklyn, New York: A Thematic Analysis.

The 2016 outbreak of Zika virus (ZIKV) infected millions and resulted in thousands of infants born with malformations. Though the clusters of severe birth defects resulting from this outbreak have subsided, ZIKV continues to be a concern throughout much of Latin America and the Caribbean. Travel and sexual intercourse remain the dominant transmission risk factors for women of reproductive age and their partners. This is particularly true for communities in Brooklyn, New York, that comprise large immigrant and foreign-born populations. Practitioners of public health understand little about how women at risk for ZIKV are most likely to receive information about the virus or who they trust most to provide that information. In the context of five focus group discussions, this study explored the knowledge and communication preferences of 20 women of reproductive age in Central Brooklyn. Results derived from a thematic analysis suggest that while most women are familiar with mosquitos as ZIKV vectors, knowledge of sexual transmission is considerably lower. Many respondents believe that only women who are pregnant or trying to become pregnant are at risk, and public health agencies, such as the U.S. Centers for Disease Control and Prevention, remain the most trusted sources of information. These findings can support more effective communication about the risks of ZIKV infection and other vector-borne diseases to women in New York City and similar urban communities.

Global health and climate action: achievements and imperatives from COP28.

SThe 28th Conference of the Parties (COP28) to the United Nations Framework Convention on Climate Change marked a step-change forward in integrating health into the global climate change agenda. For the first time, there was a dedicated 'health' day, US$1 billion (A$1.5 billion) in climate-health financing was announced, and a Declaration on Climate and Health was signed by 148 countries. Australia also launched its National Health and Climate Strategy. A 'global stocktake' assessed progress against the Paris Agreement, emphasising the need to "transition away" from fossil fuels in the final COP28 decision. The Loss and Damage Fund to help vulnerable countries cope with climate change was also operationalised. Less promising are a number of loopholes in the COP28 outcomes regarding the continued use of fossil fuels. Loss and Damage Fund pledges represented only 0.2% of the estimated financial assistance needed to support vulnerable countries. Australia remains one of the largest fossil fuel exporters and has yet to elaborate on the implementation and financing for its health and climate strategy. To protect global health, urgent action is needed to phase out fossil fuels and transition to renewable energy, ensuring no communities are left behind. Investment is needed to increase the resilience of communities and health services to address innumerable challenges, including those associated with climate change. COP28 saw an increased presence of public health practitioners, who can play a critical role in understanding the implications of climate change for the communities they serve and embedding responses in their practice. They are well placed to strengthen the evidence base for interventions, monitor progress, and advocate for health-promoting climate policy. COPs form an important part of how we collectively address climate change. The health sector finally has a place at the COP table. The sector now needs to become an enabler of action across sectors, as well as managing the health consequences of climate change on communities and health services. Australia hopes to host COP31 in 2026 with Pacific states, potentially providing a catalyst for strengthened resolve.

Prioritization of ethical concerns regarding HIV molecular epidemiology by public health practitioners and researchers

BackgroundHIV molecular epidemiology (HIV ME) can support the early detection of emerging clusters of new HIV infections by combining HIV sequence data routinely obtained during the clinical treatment of people living with HIV with behavioral, geographic, and sociodemographic information. While information about emerging clusters promises to facilitate HIV prevention and treatment efforts, the use of this data also raises several ethical concerns. We sought to assess how those working on the frontlines of HIV ME, specifically public health practitioners (PHPs) and researchers, prioritized these issues.MethodsEthical issues were identified through literature review, qualitative in-depth interviews, and stakeholder engagement. PHPs and researchers using HIV ME prioritized the issues using best–worst scaling (BWS). A balanced incomplete block design was used to generate 11 choice tasks each consisting of a sub-set of 5 ethical concerns. In each task, respondents were asked to assess the most and least concerning issue. Data were analyzed using conditional logit, with a Swait-Louviere test of poolability. Latent class analysis was then used to explore preference heterogeneity.ResultsIn total, 57 respondents completed the BWS experiment May–June 2023 with the Swait-Louviere test indicating that researchers and PHPs could be pooled (p = 0.512). Latent class analysis identified two classes, those highlighting “Harms” (n = 29) (prioritizing concerns about potential risk of legal prosecution, individual harm, and group stigma) and those highlighting “Utility” (n = 28) (prioritizing concerns about limited evidence, resource allocation, non-disclosure of data use for HIV ME, and the potential to infer the directionality of HIV transmission). There were no differences in the characteristics of members across classes.ConclusionsThe ethical issues of HIV ME vary in importance among stakeholders, reflecting different perspectives on the potential impact and usefulness of the data. Knowing these differences exist can directly inform the focus of future deliberations about the policies and practices of HIV ME in the United States.

A hypothetical intervention to reduce inequities in anxiety for Multiracial people: simulating an intervention on childhood adversity.

Multiracial people report higher mean Adverse Childhood Experiences (ACEs) scores and prevalence of anxiety than other racial groups. Studies using statistical interactions to estimate racial differences in ACEs-anxiety associations do not show stronger associations for Multiracial people. Using data from Waves 1 (1995-97) through 4 (2008-09) of the National Longitudinal Study of Adolescent to Adult Health (Add Health), we simulated a stochastic intervention over 1,000 resampled datasets to estimate the race-specific cases averted per 1,000 of anxiety if all racial groups had the same exposure distribution of ACEs as Whites. Simulated cases averted were greatest for the Multiracial group, (median = -4.17 cases per 1,000, 95% CI: -7.42, -1.86). The model also predicted smaller risk reductions for Black participants (-0.76, 95% CI: -1.53, -0.19). CIs around estimates for other racial groups included the null. An intervention to reduce racial disparities in exposure to ACEs could help reduce the inequitable burden of anxiety on the Multiracial population. Stochastic methods support consequentialist approaches to racial health equity, and can encourage greater dialogue between public health researchers, policymakers, and practitioners.

Nutrition facts, drug facts, and model facts: putting AI ethics into practice in gun violence research.

Firearm injury research necessitates using data from often-exploited vulnerable populations of Black and Brown Americans. In order to reduce bias against protected attributes, this study provides a theoretical framework for establishing trust and transparency in the use of AI with the general population. We propose a Model Facts template that is easily extendable and decomposes accuracy and demographics into standardized and minimally complex values. This framework allows general users to assess the validity and biases of a model without diving into technical model documentation. We apply the Model Facts template on 2 previously published models, a violence risk identification model and a suicide risk prediction model. We demonstrate the ease of accessing the appropriate information when the data are structured appropriately. The Model Facts template is limited in its current form to human based data and biases. Like nutrition facts, it will require educational programs for users to grasp its full utility. Human computer interaction experiments should be conducted to ensure model information is communicated accurately and in a manner that improves user decisions. The Model Facts label is the first framework dedicated to establishing trust with end users and general population consumers. Implementation of Model Facts into firearm injury research will provide public health practitioners and those impacted by firearm injury greater faith in the tools the research provides.

Does oral iron and folate supplementation during pregnancy protect against adverse birth outcomes and reduced neonatal and infant mortality in Africa: A protocol for a systematic review and meta-analysis?

Globally, one-third of pregnant women are at risk of iron deficiency, particularly in the African region. While recent findings show that iron and folate supplementation can lower the risk of adverse birth outcomes and childhood mortality, our understanding of its impact in Africa remains incomplete due to insufficient evidence. This protocol outlines the systematic review steps to investigate the impact of oral iron and folate supplementation during pregnancy on adverse birth outcomes, neonatal mortality and infant mortality in Africa. MEDLINE, PsycINFO, Embase, Scopus, CINAHL, Web of Science, and Cochrane databases were searched for published articles. Google Scholar and Advanced Google Search were used for gray literature and nonindexed articles. Oral iron and/or folate supplementation during pregnancy is the primary exposure. The review will focus on adverse birth outcomes, neonatal mortality and infant mortality. Both Cochrane Effective Practice and Organization of Care and Newcastle-Ottawa Scale risk of bias assessment tools will be used. Meta-analysis will be conducted if design and data analysis methodologies permit. This systematic review and meta-analysis will provide up-to-date evidence about iron and folate supplementation's role in adverse birth outcomes, neonatal mortality and infant mortality in the African region. This review will provide insights that help policymakers, program planners, researchers, and public health practitioners interested in working in the region. CRD42023452588.

Advancing Evidence-Based Public Health Policy: How Core Component Thinking Can Illuminate the Multilevel Nature of Public Health Policy.

A growing body of literature uses the concept of core components to better understand small-scale programmatic interventions. Instead of interventions being viewed as unitary "black boxes," interventions are viewed as configurations of core components, which are the parts of interventions that carry their causal potential and therefore need to be reproduced with fidelity to produce the intended effect. To date, the concept of core components has not been as widely applied to public health policy interventions as it has to programmatic interventions. The purpose of this topical review is to familiarize public health practitioners and policy makers with the concept of core components as applied to public health policy interventions. Raising the profile of core component thinking can foster mindful adaptation and implementation of public health policy interventions while encouraging further research to enhance the supporting evidence base. We present 3 types of multilevel interactions in which the core components of a public health policy intervention produce effects at the population level by (1) seeking to directly affect individual behavior, (2) facilitating adoption of programmatic interventions by intermediaries, and (3) encouraging intermediaries to take action that can shape changes in upstream drivers of population health. Changing the unit of analysis from whole policies to core components can provide a basis for understanding how policies work and for facilitating novel evidence-generating strategies and rapid evidence reviews that can inform future adaptation efforts.

In COVID Times: Scholars of Health and Medicine Meet Disaster Studies.

This essay builds on the exciting trove of disaster social science research surfacing since the earliest days of the COVID-19 pandemic. It tracks the ways that both practitioners of medicine and public health, and their social science analogues, have approached the pandemic, explicitly considering the ways they reached for new concepts to explain the temporal phenomena presented by COVID-19 and its global course. The essay highlights a series of interviews conducted in the first two years of the pandemic as part of the COVIDCalls podcast. COVID is the moment for a scholarly convergence that was missed after September 11, and again after Hurricane Katrina, and should not be missed again. Accordingly, this essay explores themes where medicine/health studies and disaster studies seem to offer great help to one another in making sense of our COVID times: the origins of disaster, disasters in combination, and the end of a disaster.

Public Health: Policy, Law and Right

Public health, as delineated in legal parlance, emanates as the discipline devoted to safeguarding the collective well-being, enhancing community health through educational initiatives, policy formulation, and diligent research aimed at injury prevention. Characterizations of public health may vary contingent upon individual perspectives. Practitioners within the realm of public health facilitate global engagement, addressing communal health challenges comprehensively, and wielding influence over policies shaping societal health. Public health law, in turn, constitutes the systematic study of governmental authority and obligations pertaining to the maintenance of conditions conducive to public health, while also delineating constraints on state power vis-à-vis fundamental rights such as privacy, liberty, and other legally safeguarded interests of individuals. This legal framework regulates the operational ambit of public health endeavors. Integral to the multifaceted domain of public health are an array of disciplines including biology, education, sociology, business, and others, each contributing distinctively to its overarching objectives. The imperative for bolstering public health infrastructure becomes conspicuous amidst a workforce deficit juxtaposed against a burgeoning populace within the United States. Notably, one-third of the requisite workforce remains unfilled, jeopardizing the capacity to identify, mitigate, and forestall emergent public health exigencies. The raison d'être of public health lies in its mission to foster and safeguard the populace's well-being. Whereas medical practitioners focus on remedial interventions for the ailing, public health practitioners’ endeavour to preclude afflictions and injuries proactively, thereby espousing a paradigm of wellness promotion through advocacy for healthy behaviours.

Research outcomes informing the selection of public health interventions and strategies to implement them: A cross-sectional survey of Australian policy-maker and practitioner preferences

BackgroundA key role of public health policy-makers and practitioners is to ensure beneficial interventions are implemented effectively enough to yield improvements in public health. The use of evidence to guide public health decision-making to achieve this is recommended. However, few studies have examined the relative value, as reported by policy-makers and practitioners, of different broad research outcomes (that is, measures of cost, acceptability, and effectiveness). To guide the conduct of research and better inform public health policy and practice, this study aimed at describing the research outcomes that Australian policy-makers and practitioners consider important for their decision-making when selecting: (a) public health interventions; (b) strategies to support their implementation; and (c) to assess the differences in research outcome preferences between policy-makers and practitioners.MethodAn online value-weighting survey was conducted with Australian public health policy-makers and practitioners working in the field of non-communicable disease prevention. Participants were presented with a list of research outcomes and were asked to select up to five they considered most critical to their decision-making. They then allocated 100 points across these – allocating more points to outcomes perceived as more important. Outcome lists were derived from a review and consolidation of evaluation and outcome frameworks in the fields of public health knowledge translation and implementation. We used descriptive statistics to report relative preferences overall and for policy-makers and practitioners separately.ResultsOf the 186 participants; 90 primarily identified as policy-makers and 96 as public health prevention practitioners. Overall, research outcomes of effectiveness, equity, feasibility, and sustainability were identified as the four most important outcomes when considering either interventions or strategies to implement them. Scores were similar for most outcomes between policy-makers and practitioners.ConclusionFor Australian policy-makers and practitioners working in the field of non-communicable disease prevention, outcomes related to effectiveness, equity, feasibility, and sustainability appear particularly important to their decisions about the interventions they select and the strategies they employ to implement them. The findings suggest researchers should seek to meet these information needs and prioritize the inclusion of such outcomes in their research and dissemination activities. The extent to which these outcomes are critical to informing the decision of policy-makers and practitioners working in other jurisdictions or contexts warrants further investigation.

Understanding the Impact of Communicating Uncertainty About COVID-19 in the News: Randomized Between-Subjects Factorial Experiment.

Whether and how the uncertainty about a public health crisis should be communicated to the general public have been important and yet unanswered questions arising over the past few years. As the most threatening contemporary public health crisis, the COVID-19 pandemic has renewed interest in these unresolved issues by both academic scholars and public health practitioners. The aim of this study was to investigate the impact of communicating uncertainty about COVID-19-related threats and solutions on individuals' risk perceptions and misinformation vulnerability, as well as the sequential impact of these effects on health information processing and preventative behavioral intentions. A 2×2 (threat uncertainty [presence vs absence]×solution uncertainty [presence vs absence]) full-fractional between-subjects online experiment was conducted with 371 Chinese adults. Focusing on the discussion of whether the asymptomatic cases detected during the COVID-19 pandemic would further lead to an uncontrolled pandemic, news articles were manipulated in terms of whether the infectiousness of asymptomatic cases and the means to control the transmission are presented in terms of their certainty or uncertainty. Participants were randomly assigned to one of the four experimental conditions, being instructed to read one news article. After reading the news article assigned, participants were asked to respond to a series of questions to assess their cognitive and behavioral responses. Individuals were more susceptible to believing false COVID-19-related information when a certain threat and uncertain solution were framed in the news article. Moreover, individuals' perceptions of crisis severity increased when exposed to news information containing uncertain solutions. Both misinformation vulnerability and perceived severity were positively associated with information processing. Information seeking was positively associated with protective behavioral intention, whereas information avoidance was negatively associated with protective behavioral intention. Our findings imply that uncertainty, depending on its aspect, can be effectively communicated to the public during an emerging public health crisis. These results have theoretical and practical implications for health communicators and journalists. Given its limited influence on individuals' cognitive and behavioral responses, uncertainty related to a health threat should be disseminated to meet the public's expectation of information transparency. However, caution is advised when communicating uncertainty related to potential solutions, as this factor exhibited a mixed impact on individual responses during a crisis.

Bridging the gap between research evidence and its implementation in public health practice: case studies of embedded research model

AimTo investigate the potential of embedded research in bridging the gap between research evidence and its implementation in public health practice.MethodsUsing a case study methodology, semi-structured interviews were conducted with 4 embedded researchers, 9 public health practitioners, and 4 other stakeholders (2 teachers and 2 students) across four case study sites. Sites and individuals were purposively selected. Sites included two local authorities, one secondary school, and one sports organisation. Thematic data analysis was adopted to analyse the qualitative data.ResultsFour themes were identified: (1) building and maintaining relationships, (2) working with stakeholders, (3) informing practice, and (4) critical reflection.ConclusionsEmbedded researchers build and maintain relationships with practitioners and other stakeholders to produce research. Evidence from the co-produced research informs future practice and research to improve service and delivery rendered to the public. Thus, embedded researchers use their role to bridge the research evidence - implementation gap in public health practice.
