BACKGROUND: The COVID-19 pandemic has significantly affected Los Angeles County, and disproportionately impacted Black and Latino populations who experienced disparities in rates of infection, hospitalizations, morbidity, and mortality. The University of Southern California (USC), USC Keck School of Medicine, Southern California Clinical and Translational Science Institute (SC CTSI), USC Mann School of Pharmacy and Pharmaceutical Sciences, Annenberg School for Journalism and Communication, and Children's Hospital Los Angeles (CHLA) will launch a collaborative public health campaign called VaccinateLA...

UNLABELLED: Debates over trade liberalization vs. protectionism have becoming increasingly relevant as the world moves through a contentious era of economic globalization. This is particularly true in the United States, where an elite consensus on the merits of free trade has fractured in recent years. While we know a good deal about the economic and cultural determinants of trade opinion, we know little about how attitudes toward government may matter. Here, I address this oversight by examining the relationship between political trust and trade support...

BACKGROUND: The coronavirus pandemic (COVID-19) has also emerged as an infodemic, thereby worsening the harm of the pandemic. This situation has highlighted the need for a deeply rooted understanding of the health information-seeking behaviors (HISBs) of people. OBJECTIVE: The aim of this paper was to review and provide insight regarding methodologies and the construct of content in HISB surveys by answering the following research question: what are the characteristics of the measurement tools for assessing HISBs in nationally representative surveys around the world? METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was used as the framework for this study...

The complementary effects of genre-specific media use and information-seeking behaviors on cancer prevention behaviors have been understudied in cancer communication literature. A secondary analysis of the Annenberg National Health Communication Survey (ANHCS) was conducted to investigate the effects of two types of televised media content (i.e., news and entertainment programs) on three types of cancer screening behaviors through active health information seeking behavior (HISB) from other mass media. The results show that routine entertainment and news television viewing significantly predicted HISB above and beyond demographic variables and perceived health status...

Political orientation (Republican/Democrat and conservative/liberal) and political environment (geo-spatial political party affiliated voting patterns) are both associated with various health outcomes, including mortality. Modern disease etiology in the U.S. suggests that many of our health outcomes derive from behaviors and lifestyle choices. Thus, we examine the associations of political orientation and political environment with health behaviors. We used the Annenberg National Health Communication Survey (ANHCS) data, which is a nationally representative U...

This study investigated whether individuals with different socioeconomic status (SES) should be provided differently tailored health messages to promote healthy dietary behaviour (HDB). Prior research has suggested that people with different SESs tend to exhibit different types of beliefs about health, but it remains unclear how SES interacts with these beliefs to influence health outcomes. To better understand the differences in HDB between high- and low-SES populations and propose effective intervention strategies, we examined (i) how SES is associated with HDB, (ii) how internal health locus of control (HLC) and powerful others HLC are associated with HDB, and (iii) how SES interacts with internal and powerful others HLC to influence HDB...

This study examined proposed direct and mediating relationships in the Structural Influence Model (SIM) of Communication within the chronic disease context. Using data from the Annenberg National Health Communication Survey (N = 14,472), we tested the potential mediating roles of information seeking, information scanning, and social capital between social determinants of health and four chronic disease risk behaviors: exercise level, fruit and vegetable intake, cigarette smoking, and excessive alcohol use...

Varying types of health information sources may influence health outcomes, but not much is known about their impact. The purpose of our study was to explore the association between health information sources and individuals' health status. A total of 14,966 participants who responded to the Annenberg National Health Communication Survey between 2005 and 2012 were included. Controlling for demographics, comorbidities, communication patterns, and socioeconomic status, we utilized regression analysis to examine the relationship between sources of health information and perceived health status...

BACKGROUND: Health literacy among caregivers of food allergic individuals (FAIs) is poorly described, as are the information sources sought regarding food allergy. OBJECTIVE: To assess the association among health literacy, trust in online sources of information, and food allergy quality of life (QoL) and self-efficacy. METHODS: An online survey was administered to caregivers of FAIs assessing health literacy (Newest Vital Sign [NVS] and the eHeals Internet health literacy index), trust in online information (Hargittai Internet credibility index and Annenberg National Health Communication Survey [ANHCS]), QoL (Food Allergy Quality of Life Parental Burden), and self-efficacy (Food Allergy Self-Efficacy Questionnaire [FASEQ])...

We proposed a conceptual model to predict health information-seeking behaviors (HISBs) from three different sources (family, the Internet, doctors). To test the model, a structural equation modeling (SEM) analysis was conducted using data from the 2012 Annenberg National Health Communication Survey (ANHCS) (N = 3,285). Findings suggest higher social support from family predicts higher trust in health information from family members (abbreviated as trust in this article). Trust is positively related to HISBs from all three sources, with the path linking trust to HISB from family being the strongest...

BACKGROUND: Children in the United States (US) are frequently exposed to advertisements for high-fat, high-sugar (HFHS) foods, which is linked to greater demand for and consumption of those foods. Restricting advertisements for HFHS foods may be a viable obesity prevention strategy-however, public support for policy change is unclear. METHODS: A secondary analysis of the 2012 Annenberg National Health Communication Survey was conducted. Respondents (N = 1838) were 53...

Despite their understanding of the links between (a) information seeking and scanning and (b) health outcomes, researchers still know relatively little about the impact of information behaviors on people's disease-related beliefs and attitudes. The goal of this study was to validate findings linking information and health behaviors and to assess whether information seeking and scanning are associated with beliefs about the effectiveness of heart disease and colon cancer risk prevention behaviors (in regard to exercise, controlling one's diet to prevent overweight/obesity, and daily fruit and vegetable intake), as well as determine whether the effects of seeking versus scanning on these beliefs differ...

BACKGROUND: Treating patients with hematologic malignancies can be challenging for physicians because of the rapidly evolving standards of care and relatively low incidence of these diseases. OBJECTIVE: To identify clinical challenges among hematologists and medical oncologists regarding the provision of care to patients with chronic myeloid leukemia (CML), acute lymphoblastic leukemia (ALL), or B-cell lymphomas. Methods Hematologists and medical oncologists in active practice in the United States and who have a case load of ≥ 1 patient a year with CML, ALL, or B-cell lymphoma were recruited...

PURPOSE: The goal of the present study was to examine suicide acceptability as a mechanism of suicide clustering in adolescents. METHODS: Data were drawn from The National Annenberg Survey of Youth, a sample of 3302 adolescents aged 14-22 collected between 2002 and 2004. RESULTS: Results indicated that beliefs of the acceptability of suicide partially mediated the effect of exposure to suicide (defined as knowing someone who attempted or completed suicide) on 1) serious suicidal ideation and 2) suicide planning behaviors...

PURPOSE: This study aims to identify people who do not actively seek out health information and the demographic characteristics of Inactive Seekers. The possible determinants of inactive seeking behaviors are also explored. DESIGN AND MEASUREMENTS: A total of 14,420 survey respondents were drawn from the 2009 Annenberg National Health Communication Survey (ANHCS) data. K-means clustering was used to discriminate Inactive Seekers from Active Seekers. The inactive information seeker group was formed based on their experience with health information seeking...

There is increasing concern that the media present conflicting health information on topics including cancer screening and nutrition. Although scholars have speculated that exposure to this information leads to increased public confusion, less trust in health recommendations, and less engagement in health behaviors, there is a lack of empirical research that directly addresses the role of media exposure to conflicting information. Using data from the Annenberg National Health Communication Survey, this study finds that exposure to conflicting information on the health benefits and risks of, for example, wine, fish, and coffee consumption is associated with confusion about what foods are best to eat and the belief that nutrition scientists keep changing their minds...

A newly-approved carotid patch, derived from porcine small intestinal submucosa (SIS), is thought to allow functional tissue regeneration by acting as a biologic scaffold of extracellular matrix. We report three cases of asymptomatic pseudoaneurysm after SIS patch closure. At exploration there were intact suture lines, no growth from cultures, and central patch herniation. Histopathologic examination showed postendarterectomy neointima in the artery and disorganized collagen in the pseudoaneurysm. SIS patch remnants adjacent to macrophage infiltration and neovascularization indicated ongoing processes of degradation and synthesis...

This article examines how everyday media use and interpersonal communication for health information could influence health behaviors beyond intervention or campaign contexts. The authors argue that interpersonal communication works as an independent information channel and mediates the relation between media channels and health behaviors. In addition, the authors investigate whether interpersonal communication differently influences the relation between media connections and health behaviors for more and less educated individuals...
