The Communication Infrastructure as a Social Determinant of Health: Implications for Health Policymaking and Practice

Variations in Unmet Health Care Needs by Perceptions of Social Media Health Mis- and Disinformation, Frequency of Social Media Use, Medical Trust, and Medical Care Discrimination: Cross-Sectional Study

Background

Unmet need for health care is defined as choosing to postpone or completely avoid necessary medical treatment despite having a need for it, which can worsen current conditions or contribute to new health problems. The emerging infodemic can be a barrier that prevents people from accessing quality health information, contributing to lower levels of seeking medical care when needed.

Objective

We evaluated the association between perceptions of health mis- and disinformation on social media and unmet need for health care. In addition, we evaluated mechanisms for this relationship, including frequency of social media use, medical trust, and medical care discrimination.

Methods

Data from 3964 active adult social media users responding to the 2022 Health Information National Trends Survey 6 (HINTS 6), a nationally representative survey, were analyzed. The outcome was unmet need for medical care, defined as delaying or not getting the necessary medical care. The predictor variables were perception of social media health mis- and disinformation, frequency of social media use, level of trust in the health care system, and perceived racial and ethnic discrimination when receiving health care.

Results

Multivariable logistic regression models indicated that perception of substantial social media health mis- and disinformation (odds ratio [OR] 1.40, 95% CI 1.07-1.82), daily use of social media (OR 1.34, 95% CI 1.01-1.79), low medical trust (OR 1.46, 95% CI 1.06-2.01), and perceived discrimination (OR 2.24, 95% CI 1.44-3.50) were significantly associated with a higher likelihood of unmet need for medical care. Unmet need among adults who did not use social media daily and who did not perceive substantial mis- and disinformation (24%; 95% CI 19%-30%) was lower compared to daily social media users who perceived substantial mis- and disinformation (38%; 95% CI 32%-43%). Adults who perceived substantial mis- and disinformation and had low trust in health care had the highest probability of reporting unmet need (43%; 95% CI 38%-49%) compared to the other three groups. Adults who perceived substantial mis- and disinformation and experienced medical care discrimination had a statistically significant higher probability of reporting unmet need (51%; 95% CI 40%-62%) compared to adults who did not experience medical care discrimination and did not perceive substantial mis- and disinformation (29%; 95% CI 26%-32%).

Conclusions

Unmet need for medical care was higher among individuals who perceived a substantial degree of social media mis- and disinformation, especially among those who used social media daily, did not trust the health care system, and experienced racial or ethnic discrimination when receiving health care. To counter the negative effects of social media mis- and disinformation on unmet need for health care, public health messaging must focus on daily social media users as well as improving trust and reducing structural racism in the health care system.

Examining health apps and wearable use in improving physical and mental well-being across U.S., China, and Singapore

Health apps and wearables are touted to improve physical health and mental well-being. However, it is unclear from existing research the extent to which these health technologies are efficacious in improving physical and mental well-being at a population level, particularly for the underserved groups from the perspective of health equity and social determinants. Also, it is unclear if the relationship between health apps and wearables use and physical and mental well-being differs across individualistic, collectivistic, and a mix of individual-collectivistic cultures. A large-scale online survey was conducted in the U.S. (individualist culture), China (collectivist culture), and Singapore (mix of individual-collectivist culture) using quota sampling after obtaining ethical approval from the Institutional Review Board (IRB-2021-262) of Nanyang Technological University (NTU), Singapore. There was a total of 1004 respondents from the U.S., 1072 from China, and 1017 from Singapore. Data were analyzed using multiple regression and negative binomial regression. The study found that income consistently had the strongest relationship with physical and mental well-being measures in all three countries, while the use of health apps and wearables only had a moderate association with psychological well-being only in the US. Health apps and wearables were associated with the number of times people spent exercising and some mental health outcomes in China and Singapore, but they were only positively associated with psychological well-being in the US. The study emphasizes the importance of considering the social determinants, social-cultural context of the population, and the facilitating conditions for the effective use of digital health technologies. The study suggests that the combined use of both health apps and wearables is most strongly associated with better physical and mental health, though this association is less pronounced when individuals use only apps or wearables.

Mitigating Health and Science Misinformation: A Scoping Review of Literature from 2017 to 2022

Literature on how to address misinformation has rapidly expanded in recent years. The aim of this scoping review was to synthesize the growing published literature on health and science misinformation mitigation interventions. English-language articles published from January 2017 to July 2022 were included. After title/abstract screening, 115 publications (148 empirical studies) met inclusion criteria and were coded for sample characteristics, topics, mitigation strategies, research methods, outcomes, and intervention efficacy. A marked increase in misinformation mitigation research was observed in 2020-2022. COVID-19, vaccines, and climate change were the most frequently addressed topics. Most studies used general population samples recruited online; few focused on populations most vulnerable to misinformation. Most studies assessed cognitive outcomes (e.g., knowledge), with fewer assessing health behavior, communication behavior, or skills. Correction (k = 97) was the most used misinformation mitigation strategy, followed by education and other literacy initiatives (k = 39) and prebunking/inoculation (k = 24). Intervention efficacy varied, with 76 studies reporting positive, 17 reporting null, and 68 reporting mixed results. Most misinformation mitigation interventions were limited to short-term online experiments focused on improving cognitive outcomes. Priority research areas going forward include expanding and diversifying study samples, scaling interventions, conducting longitudinal observations, and focusing on communities susceptible to misinformation.

COVID-19 risk communication gaps, needs, and strategies related to pandemic preparedness plans among vulnerable, Black American subgroups: A qualitative study

OBJECTIVE

Improving current and future risk communication plans is critical to mitigate the COVID-19 pandemic and begin to prepare for future pandemics. Minority groups, particularly African Americans, have been limited in engagement to prepare these plans which has been demonstrated to be disadvantageous. We report findings from a qualitative study that describes gaps, needs, and strategies to improve communication among vulnerable, Black American subgroups during the COVID-19 pandemic.

METHODS

Sixty-two Black Americans in uniquely, vulnerable subgroups participated in qualitative, semi-structured interviews from May to September 2020. Thematic analyses were used to identify themes.

RESULTS

Participants were 16 essential workers, 16 parents, 15 young adults, and 15 individuals with underlying medical conditions. Emerging themes were: (1) Poor communication and miscommunication fueled fear and confusion; (2) Information sources and channels: How do I choose one?; (3) Communication needs were simple yet complex; (4) All information sources are not trusted information sources; (5) Preferred yet trusted channels and types of information; and (6) Dissemination of COVID Research: Why and How. Subgroups varied in information sources and processes for choosing the source, communication needs, and channels and types of information needed. They shared why they did and did not trust certain sources along with the importance of COVID research dissemination to promote informed decision-making throughout the pandemic.

DISCUSSION

This study found that Black American subgroups had diverse, yet trusted and non-trusted messages, messengers, and strategies for communication and wanted research results disseminated. We describe multi-level stakeholders and strategies to help improve risk communication for pandemics, and potentially preparedness and health outcomes.

Understanding Psychosocial Determinants of PrEP Uptake Among Cisgender Women Experiencing Heightened HIV Risk: Implications for Multi-Level Communication Intervention

Pre-exposure prophylaxis (PrEP) is a highly effective daily pill that decreases the likelihood of HIV acquisition by up to 92% among individuals at risk for HIV. PrEP can be discretely used, autonomously controlled, and in place at the time of risk exposure, making it an especially promising method for HIV prevention for cisgender women (CGW). But, PrEP is underutilized by CGW relative to the demonstrable need. We apply the Integrative Model of Behavioral Prediction to identify the critical psychosocial factors that shape CGW's intentions to use PrEP and their relevant underlying beliefs. We surveyed (N = 294) community- and clinic-recruited PrEP eligible CGW to understand the relative importance of attitudes, norms, and efficacy in shaping PrEP intentions. We utilized structural equation modeling to identify the relevant paths. We inspected the summary statistics in relation to three message three selection criteria. We identified beliefs that demonstrated (1) an association with intention, (2) substantial room to move the population, (3) practicality as a target for change through communication intervention. Results show that PrEP awareness was low. When women learned about PrEP, they voiced positive intentions to use it. There were significant and positive direct effects of SE (0.316***), attitudes (0.201**), and subjective norms (0.249***) on intention to initiate PrEP. We illustrate the strategic identification of beliefs within the relevant paths using the 3 belief selection criteria. We also discuss implications for social and structural communication interventions to support women's HIV prevention.

Examining Theoretical Frameworks and Antecedents of Health Apps and Wearables Use: A Scoping Review

The advancement of health apps and wearables has garnered substantial academic attention, particularly in examining why individuals decide to use or not use them. In response to the extensive body of research on this topic, we conducted a scoping review of 61 articles published from 2007 to 2022, aiming to examine the dominant theoretical frameworks and antecedents of health apps and wearables use. The findings demonstrated that the dominant theoretical frameworks within this domain were rooted in the human-computer interaction theories, notably the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology. Next, our review identified four levels of antecedents: technological, individual, societal, and policy. At the technological level, emphasis was placed on functionality, reliability, and technological infrastructure. Individual antecedents encompassed socio-demographics, personality traits, cognitive responses to benefits and risks, emotional and affective responses, self-efficacy, and digital literacy. Societal antecedents highlighted the role of social networks and social norms, while policy antecedents elaborated on laws, regulations, and guidelines that encouraged health technology adoption. Our discussion illuminated that the evolving trend of theoretical frameworks in health apps and wearables use research, initially rooted in human-computer interaction, is progressively moving toward more comprehensive perspectives. We further underscored the importance of delving into societal and policy antecedents, which often are overshadowed by the more commonly discussed technological and individual factors. In conclusion, we advocated for a multi-stakeholder collaborative network approach, as this would enable communication researchers to understand the use of health apps and wearables more comprehensively.

Health risk communication and infodemic management in Iran: development and validation of a conceptual framework

OBJECTIVE

The COVID-19 pandemic exposed significant gaps in Iran's and other health systems' risk communication. The accompanying infodemic undermined policy responses, amplified distrust in government and reduced adherence to public health recommendations among the Iranian population. This study aimed to develop a conceptual framework for health risk communication and infodemic management (RCIM) during epidemics and health emergencies in Iran that could have potential applications in other contexts.

DESIGN

This study was designed in two phases. Phase 1 involved semistructured qualitative interviews with key informants to explore effective RCIM strategies across public health settings in Iran and to develop a conceptual framework. Phase 2 involved revising the framework based on feedback from an online expert panel regarding its comprehensiveness and validity.

SETTING

Provincial/national public health settings in Iran.

PARTICIPANTS

Twenty key informants from provincial and national public health authorities who contributed to COVID-19 response programmes participated in interviews. Nine experts from diverse academic disciplines, provincial and national settings, and geographical locations participated in an online expert panel.

RESULTS

The conceptual model was created based on qualitative interviews and expert panel discussions and was structured according to six pillars of the WHO health system framework: leadership and governance, information, health workforce and financial resources, along with media and community. Leadership and governance, including trustworthy leaders, were recommended as the foundation for developing RCIM in Iran. Developing an official strategy with information infrastructures, including high-quality surveillance systems, identified personnel and training for specialists among the health workforce, financial resources, communication channels and community engagement were recognised as other dimensions for developing health risk communication in Iran.

CONCLUSION

The proposed framework represents a step toward establishing a national RCIM strategy in Iran. Further validation of the conceptual framework and experiments on how it could potentially influence policy and practice is recommended. This model has the potential to be applied in other contexts in its current form or as the foundation for customised local versions.

Racial residential segregation and COVID-19 vaccine uptake: an analysis of Georgia USA county-level data

BACKGROUND

Foundational literature demonstrates that racial residential segregation results in poorer health outcomes for Black people than white people due to a variety of social determinants of health. COVID-19 vaccine uptake is important for better health outcomes, regardless of race. The COVID-19 pandemic has elevated concerns about racial health disparities but with little discussion of racial residential segregation as a predictor of disparate health outcomes. This paper investigates the relationship between racial residential segregation and COVID-19 vaccine uptake using county level data from the State of Georgia (USA).

METHODS

Using publicly available data, regression analysis is conducted for 138 of the 159 counties in Georgia USA, using a dissimilarity index that describes county level differences in racial residential segregation. The primary independent variable is Black-white differences in vaccine uptake at the county level. The analytic methods focus on a spatial analysis to support information for county level health departments as the basis for health policy and resource allocation.

RESULTS

Constructing a variable of the difference in vaccination rates between Black and white residents we find that Black-white differences in COVID-19 vaccination are most notable in the 69 most segregated of the 159 counties in Georgia. A ten-point lower segregation index is associated with an improvement in the Black-white vaccination gap of 1.5 percentage points (95% CI -0.31, -0.00). Income inequality and access to health care resources, such as access to a primary care physician, also predict Black-white differences in vaccination rates at the county level. Suggested mapping approaches of publicly available data at a state county level, provides a resource for local policy makers to address future challenges for epidemic and pandemic situations.

CONCLUSION

County level and geospatial data analysis can inform policy makers addressing the impact of racial residential segregation on local health outcomes, even for pandemic and epidemic issues.

Communication inequalities in the COVID-19 pandemic: socioeconomic differences and preventive behaviors in the United States and South Korea

BACKGROUND

Communication inequalities are important mechanisms linking socioeconomic backgrounds to health outcomes. Guided by the structural influence model of communication, this study examined the intermediate role of health communication in the relationship between education, income, and preventive behavioral intentions during the COVID-19 pandemic in the United States and South Korea.

METHODS

The data were collected through two online surveys conducted by two professional research firms in the US (April 1-3, 2020) and South Korea (April 9-16, 2020). To test the mediating role of health communication, as well as the hypothesized relationships in the proposed model, we performed a path analysis using Mplus 6.1.

RESULTS

In analyzing survey data from 1050 American and 1175 Korean adults, we found that one's socioeconomic positions were associated with their intentions to engage in COVID-19 preventive behaviors through affecting their health communication experiences and then efficacious beliefs. Differences in education and income were associated with willingness to engage in preventive behaviors by constraining health communication among people with low levels of education and income. The findings showed notable differences and some similarities between the US and South Korea. For example, while income was positively associated with health communication in both US and South Korea, education was only significantly related to health communication in US but not in South Korea.

CONCLUSIONS

This study suggests health communication strategies such as choice of communication channels and messages to promote intention for COVID-19 prevention behaviors in particular consideration of individual differences in socioeconomic positions in countries with different cultural features. Pubic policies and health campaigns can utilize the suggestions to promote efficacy and preventive behavioral intention during early pandemics.

"We're always an afterthought"- Designing tobacco control campaigns for dissemination with and to LGBTQ +-serving community organizations: a thematic analysis

PURPOSE

Evidence-based health communication campaigns can support tobacco control and address tobacco-related inequities among lesbian, gay, bisexual, transgender, and queer (LGBTQ +) populations. Community organizations focused on LGBTQ + health (e.g., nonprofits, community centers, and community health centers) can be prime channels for delivering evidence-based health communication campaigns. However, it is unclear how to balance the goals of a) designing campaigns to support broad adoption/uptake and b) adaptation addressing the needs of diverse communities and contexts. As part of an effort to support "designing for dissemination," we explored the key challenges and opportunities staff and leaders of LGBTQ + -serving community organizations encounter when adopting or adapting evidence-based health communication campaigns.

METHODS

A team of researchers and advisory committee members conducted this study, many of whom have lived, research, and/or practice experience with LGBTQ + health. We interviewed 22 staff members and leaders of community organizations serving LGBTQ + populations in the US in early 2021. We used a team-based, reflexive thematic analysis approach.

RESULTS

The findings highlight the challenges of attempting to use health communication campaigns misaligned with the assets and needs of organizations and community members. The three major themes identified were as follows: (1) available evidence-based health communication campaigns typically do not sufficiently center LGBTQ + communities, (2) negotiation regarding campaign utilization places additional burden on practitioners who have to act as "gatekeepers," and (3) processes of using health communication campaigns often conflict with organizational efforts to engage community members in adoption and adaptation activities.

CONCLUSIONS

We offer a set of considerations to support collaborative design and dissemination of health communication campaigns to organizations serving LGBTQ + communities: (1) develop campaigns with and for LGBTQ + populations, (2) attend to the broader structural forces impacting campaign recipients, (3) support in-house testing and adaptations, and (4) increase access to granular data for community organizations.

Do Americans Lacking a Local Orthopaedic Surgeon Have Adequate Broadband for Telehealth?

BACKGROUND

Although telehealth holds promise in expanding access to orthopaedic surgical care, high-speed internet connectivity remains a major limiting factor for many communities. Despite persistent federal efforts to study and address the health information technology needs of patients, there is limited information regarding the current high-speed internet landscape as it relates to access to orthopaedic surgical care.

QUESTIONS/PURPOSES

(1) What is the distribution of practicing orthopaedic surgeons in the United States relative to the presence of broadband internet access? (2) What geographic, demographic, and socioeconomic factors are associated with the absence of high-speed internet and access to a local orthopaedic surgeon?

METHODS

The Federal Communications Commission (FCC) Mapping Broadband in America interactive tool was used to determine the proportion of county residents with access to broadband-speed internet for all 3141 US counties. Data regarding the geographic distribution of orthopaedic surgeons and county-level characteristics were obtained from the 2015 Physician Compare National Downloadable File and the Area Health Resource File, respectively. The FCC mapping broadband public use files are considered the most comprehensive datasets describing high-speed internet infrastructure within the United States. The year 2015 represents the most recently available FCC data for which county-level broadband penetration estimates are available. Third-party audits of the FCC data have shown that broadband expansion has been slow over the past decade and that many large improvements have been driven by changes in the reporting methodology. Therefore, we believe the 2015 FCC data still hold relevance. The primary outcome measure was the simultaneous absence of at least 50% broadband penetration and at least one orthopaedic surgeon practicing in county limits. Statistical analyses using Kruskal-Wallis tests and multivariable logistic regression were conducted to assess for factors associated with inaccessibility to orthopaedic telehealth. All statistical tests were two-sided with a significance threshold of p < 0.05.

RESULTS

In 2015, 14% (448 of 3141) of counties were considered "low access" in that they both had no orthopaedic surgeons and possessed less than 50% broadband access. A total of 4,660,559 people lived within these low-access counties, representing approximately 1.4% (4.6 million of 320.7 million) of the US population. After controlling for potential confounding variables, such as the age, sex, income level, and educational attainment, lower population density per square mile (OR 0.92 [95% confidence interval (CI) 0.90 to 0.94]; p < 0.01), a lower number of primary care physicians per 100,000 (OR 0.88 [95% CI 0.81 to 0.97]; p < 0.01), a higher unemployment level (OR 1.3 [95% CI 1.2 to 1.4]; p < 0.01), and greater number preventable hospital stays per 100,000 (OR 1.01 [95% CI 1.01 to 1.02]; p < 0.01) were associated with increased odds of being a low-access county (though the effect size of the finding was small for population density and number of primary care physicians). Stated another way, each additional person per square mile was associated with an 8% (95% CI 6% to 10%; p < 0.01) decrease in the odds of being a low-access county, and each additional percentage point of unemployment was associated with a 30% (95% CI 20% to 40%) increase in the odds of being a low-access county.

CONCLUSION

Despite the potential for telehealth programs to improve the delivery of high-quality orthopaedic surgical care, broadband internet access remains a major barrier to implementation. Until targeted investments are made to expand broadband infrastructure across the country, health systems, policymakers, and surgeon leaders must capitalize on existing federal subsidy programs, such as the lifeline or affordability connectivity initiatives, to reach unemployed patients living in economically depressed regions. The incorporation of internet access questions into clinic-based social determinants screening may facilitate the development of alternative follow-up protocols for patients unable to participate in synchronous videoconferencing.

CLINICAL RELEVANCE

Some orthopaedic patients lack the broadband capacity necessary for telehealth visits, in which case surgeons may pursue alternative methods of follow-up such as mobile phone-based surveillance of postoperative wounds, surgical sites, and clinical symptoms.

News coverage of Mexico's front-of-package food label policy

Objectives

To examine news coverage of Mexico’s front-of-package food labelling policy.

Methods

We used Lexis Nexis to identify newspaper articles that mention the proposed law in four Mexican newspapers representing politically centre-left and centre-right perspectives. We coded for type and valence of arguments, sources and research evidence cited.

Results

We identified N=361 relevant articles. Coverage of the front-of-package food label policy was primarily news (vs editorial/opinion). While most were neutral in tone, left-leaning newspapers had slightly more positive overall coverage compared with right-leaning newspapers, indicated by publishing more stories in favour of the policy, fewer in opposition, more propolicy arguments and more frequent inclusion of perspectives by government officials and public health advocates. Despite some evidence of bias, there was a general lack of credible opposition to the policy and mention of opponents across newspapers.

Conclusions and policy implications

The relative absence of food and beverage industry stakeholders in news coverage of the food label policy is unexpected given their documented involvement in prior food policy debates. We discuss possible reasons for their conspicuous absence and lessons for public health advocates around the globe.

Coverage and Framing of Immigration Policy in US Newspapers

Policy Points Although immigration policy is recognized as a social determinant of health, less is known about how mechanisms, such as news coverage of policy, influence intermediary and proximal health processes like seeking health care. The extent of news coverage of federal, state, and local exclusionary or integration immigration policies can influence public agendas regarding immigrant inclusion and exclusion. Exclusionary federal immigrant policies have dominated the news across the United States over the past ten years, despite active immigrant integration policymaking at national, state, and local levels.

CONTEXT

Immigration policymaking at federal, state, and local levels in the United States has proliferated in the past decade. While evidence demonstrates that immigration policy is a determinant of health, there has been limited examination of the mechanisms by which policy influences proximal health processes. News coverage has served as a central platform for debates over restrictive and inclusive immigration policies and may constitute an important health mechanism by shaping public agendas, influencing support for immigrant exclusion or inclusion, and framing policy issues, thereby influencing immigrants' social climates. This study sought to examine the extent of news coverage of exclusionary and inclusive immigration policy at federal and state levels and variations in messages about immigrants during two periods of extensive policymaking.

METHODS

We conducted a quantitative content analysis of newspapers' coverage of immigration policy between 2010 and 2013 and between 2017 and 2019. We conducted a systematic NewsBank search of articles covering legislation, lawsuits, and other policies related to immigration (n = 931). Articles were coded for policy type and level, positive or negative framing of immigrants, and other characteristics. Our analysis then compared the patterns of the two periods.

RESULTS

In both periods, the majority of coverage focused on exclusionary policies at the federal level, despite a significant increase in integration policies between 2017 and 2019. We found significant shifts in both the negative and positive framing of immigrants, from the dominant negative messages of immigrants as an economic drain to immigrants as criminals and the dominant positive messages of immigrants' economic contributions to immigrants as families.

CONCLUSIONS

Since 2010, coverage of exclusionary federal policy has consistently dominated the news, as messages have increasingly described immigrants as either criminals or part of families. We discuss the health implications and future research directions of news coverages' role in influencing the immigration policy and social contexts that have been linked to health outcomes.
