Spatial Disparities: The Role Of Nativity In Neighborhood Exposure To Alcohol And Tobacco Retailers, Georgiana Bostean, Luis A. Sánchez, Jason A. Douglas

Sociology Faculty Articles and Research

Studies of retail environment, one of the social determinants of health, document racial/ethnic disparities in exposure to alcohol and tobacco (A and T) retailers, but have largely overlooked nativity. We examined associations between A and T retailer density and rates of foreign-born Latinx and foreign-born Asian residents in California census tracts (N = 7888), using spatial regressions and controlling for population and ecological confounders (e.g., population density, zoning, residential instability, urbanicity). Socio-demographic data came from the American Community Survey (2012–2016); census tract density of A and T retailers came from geocoded addresses from state license data for off-sale alcohol distributors …

What Predicts How Safe People Feel In Their Neighborhoods And Does It Depend On Functional Status?, Alfredo J. Velasquez, Jason A. Douglas, Fangqi Guo, Jennifer W. Robinette

Health Sciences and Kinesiology Faculty Articles

Feeling unsafe in one's neighborhood is related to poor health. Features of the neighborhood environment have been suggested to inform perceptions of neighborhood safety. Yet, the relative contribution of these features (e.g., uneven sidewalks, crime, perceived neighborhood physical disorder) on perceived neighborhood safety, particularly among people with disabilities who may view themselves as more vulnerable, is not well understood. We examined whether sidewalk quality assessed by third party raters, county-level crime rates, and perceived neighborhood disorder would relate to neighborhood safety concerns, and whether functional limitations would exacerbate these links. Using data from the 2012/2014 waves of the Health and …

The Association Of Parent-Child Communication With Internet Addiction In Left-Behind Children In China: A Cross-Sectional Study, Jingjing Cai, Yun Wang, Feng Wang, Jingjing Lu, Lu Li, Xudong Zhou

Pharmacy Faculty Articles and Research

Objective: Internet addiction has emerged as a growing concern worldwide. This study aimed to compare the prevalence of Internet addiction between left-behind children (LBC) and non-left-behind children (non-LBC), and explore the role of paternal and maternal parent-child communication on LBC.

Methods: We conducted a cross-sectional survey in rural areas in Anhui, China. The complete data were available from 699 LBC and 740 non-LBC. Multivariable logistic regression was used to examine 1) whether LBC were more likely to develop Internet addiction, and 2) the association between parent-child communication and Internet addiction among LBC.

Results: LBC had a higher likelihood to report …

Fundamental Causes Of Racial And Ethnic Covid-19-Related Health Disparities, Hana Neutz

Student Scholar Symposium Abstracts and Posters

Underserved low-income communities of color in the U.S. have endured an unequal burden of COVID-19 morbidity and mortality. This pattern of pandemic-related health disparities has been pervasive throughout history. However, no known studies have simultaneously examined social and biological factors that contribute to these concerning health disparities. Therefore, this paper aims to bridge the gap by employing a scoping literature review of (1) the deleterious impacts of systemic racism on COVID-19-related outcomes; and (2) the cellular and molecular mechanisms connecting COVID-19 and hypertension (a comorbidity known to exacerbate COVID-19 severity). My findings indicate that systemic racism manifests in inequitable access …

Cannabis Use, Sedentary Behavior, And Physical Activity In A Nationally Representative Sample Of Us Adults, Lydia Q. Ong, John Belletierre, Citlali Alvorado, Paul Chavez, Vincent Berardi

Psychology Faculty Articles and Research

Background

Prior research examining the relationship between cannabis use, sedentary behavior, and physical activity has generated conflicting findings, potentially due to biases in the self-reported measures used to assess physical activity. This study aimed to more precisely explore the relationship between cannabis use and sedentary behavior/physical activity using objective measures.

Methods

Data were obtained from the 2005–2006 National Health and Nutrition Examination Survey. A total of 2,092 participants (ages 20–59; 48.8% female) had accelerometer-measured sedentary behavior, light physical activity, and moderate-to-vigorous physical activity. Participants were classified as light, moderate, frequent, or non-current cannabis users depending on how often they used …

Suppression Of Human Coronavirus 229e Infection In Lung Fibroblast Cells Via Rna Interference, Hamidreza Montazeri Aliabadi, Jennifer Totonchy, Parvin Mahdipoor, Keykavous Parang, Hasan Uludağ

Pharmacy Faculty Articles and Research

Despite extensive efforts to repurpose approved drugs, discover new small molecules, and develop vaccines, COVID-19 pandemic is still claiming victims around the world. The current arsenal of antiviral compounds did not perform well in the past viral infections (e.g., SARS), which casts a shadow of doubt for use against the new SARS-CoV-2. Vaccines should offer the ultimate protection; however, there is limited information about the longevity of the generated immunity and the protection against possible mutations. This study uses Human Coronavirus 229E as a model coronavirus to test the hypothesis that effective delivery of virus-specific siRNAs to infected cells will …

Effects Of News And Threat Perceptions On Americans’ Covid-19 Precautionary Behaviors, Riva Tukachinsky Forster, Megan A. Vendemia

Communication Faculty Articles and Research

Our study examines the relationship between news exposure at the onset of the COVID-19 pandemic, personal threat beliefs, beliefs about others’ threat perceptions, and participation in precautionary actions. A survey of 377 U.S . adults revealed a significant main effect of news exposure on various precautionary behaviors (e.g., facial mask wear, physical distancing). Personal threat beliefs and beliefs about others’ threat perceptions serve as unique mechanisms mediating the effect of news on specific CDC-recommended and less socially desirable actions. These findings can guide news sources covering health crises in a socially responsible manner.

Sars-Cov-2 Early Infection Signature Identified Potential Key Infection Mechanisms And Drug Targets, Yue Li, Ashley Duche, Michael R. Sayer, Don Roosan, Farid G. Khalafalla, Rennolds S. Ostrom, Jennifer Totonchy, Moom Roosan

Pharmacy Faculty Articles and Research

Background

The ongoing COVID-19 outbreak has caused devastating mortality and posed a significant threat to public health worldwide. Despite the severity of this illness and 2.3 million worldwide deaths, the disease mechanism is mostly unknown. Previous studies that characterized differential gene expression due to SARS-CoV-2 infection lacked robust validation. Although vaccines are now available, effective treatment options are still out of reach.

Results

To characterize the transcriptional activity of SARS-CoV-2 infection, a gene signature consisting of 25 genes was generated using a publicly available RNA-Sequencing (RNA-Seq) dataset of cultured cells infected with SARS-CoV-2. The signature estimated infection level accurately in …

Eskander, Edmond Seabright, Daniel Eid Rodriguez, Edhitt Cortez Linares, Raul Quispe Gutierrez, Juan Copajira Adrian, Daniel Cummings, Bret Beheim, Kirsten Tolstrup, Abinash Achrekar, Thomas Kraft, David E. Michalik, Michael I. Miyamoto, Adel H. Allam, L. Samuel Wann, Jagat Narula, Benjamin C. Trumble, Jonathan Stieglitz, Randall C. Thompson, Gregory S. Thomas, Hillard S. Kaplan, Michael D. Gurven

ESI Publications

Background: Atrial fibrillation is the most common arrhythmia in post-industrialized populations. Older age, hypertension, obesity, chronic inflammation, and diabetes are significant atrial fibrillation risk factors, suggesting that modern urban environments may promote atrial fibrillation.

Objective: Here we assess atrial fibrillation prevalence and incidence among tropical horticulturalists of the Bolivian Amazon with high levels of physical activity, a lean diet, and minimal coronary atherosclerosis, but also high infectious disease burden and associated inflammation.

Methods: Between 2005–2019, 1314 Tsimane aged 40–94 years (52% female) and 534 Moseten Amerindians aged 40–89 years (50% female) underwent resting 12-lead electrocardiograms to assess atrial fibrillation prevalence. …

Child Obesity Moderates The Association Between Poverty And Academic Achievement, Ashley W. Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

Childhood overweight and obesity are major public health problems in the United States. Children who experience poverty are 1.5 times more likely to suffer with overweight and 1.6 times more likely to have obesity. The extent to which overweight or obesity exacerbates the negative influence of socioeconomic inequality on child academic outcomes has not yet been examined. We estimated the effect of poverty on math and reading achievement trajectories using the Early Childhood Longitudinal Study (ECLS) Kindergarten class of 1998−1999 survey data and multilevel growth curve modeling techniques. Our findings indicate that the impact of obesity status is more pronounced …

Delgado, Alfonso Nino, Elaine C. Flores, Maria Amalia Pesantes, Juan Pablo Murillo, Luisa Elvira Belaunde, Sergio Recuenco, Robert Chuquimbalqui, Carol Zavaleta-Cortijo

World Languages and Cultures Faculty Articles and Research

"Systematic and persistent discrimination against Indigenous Peoples translates into differential health outcomes when analysed through ethnicity and/or mother tongue.1 In Peru, morbidity and mortality rates among Indigenous Peoples for COVID-19 appear to confirm this.2 The COVID-19 pandemic has highlighted the historical structural violence against Indigenous Peoples that currently takes a disproportionate toll in the Peruvian Amazon. This equally applies to Indigenous Andean Peoples and Afro Peruvians. Indigenous Peoples in voluntary isolation and those in initial contact are at highest health risk in this pandemic as they have no previous immunity against common infectious diseases, and lack access to public healthcare …

A Predictable Home Environment May Protect Child Mental Health During The Covid-19 Pandemic, Laura M. Glynn, Elyssia Poggi Davis, Joan L. Luby, Tallie Z. Baram, Curt A. Sandman

Psychology Faculty Articles and Research

Objective

Information about the adverse effects of the COVID-19 pandemic on adolescent and adult mental health is growing, yet the impacts on preschool children are only emerging. Importantly, environmental factors that augment or protect from the multidimensional and stressful influences of the pandemic on emotional development of young children are poorly understood.

Methods

Depressive symptoms in 169 preschool children (mean age 4.1 years) were assessed with the Preschool Feelings Checklist during a state-wide stay-at-home order in Southern California. Mothers (46% Latinx) also reported on externalizing behaviors with the Strengths & Difficulties Questionnaire. To assess the role of environmental factors in …

Decomposing Differences In Coronavirus Disease 2019-Related Case-Fatality Rates Across Seventeen Nations, Ashley Wendell Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

As of 1 November 2020, estimated case-fatality rates associated with coronavirus disease 2019 are not uniformly patterned across the world and differ substantially in magnitude. Given the global spatial heterogeneity in case-fatality rates, we applied the Blinder-Oaxaca regression decomposition technique to identify how putative sociodemographic, structural, and environmental sources influence variation in case-fatality rates. We show that compositional and associational differences in country-level risk factors explain a substantial proportion of the coronavirus disease 2019-related case-fatality rate gap across nations. Asian countries fair better vis-à-vis case-fatality rate differences mainly due to variation in returns to sociodemographic, structural, and environmental sources among …

Covid-19 Viral Testing Disparities In Los Angeles City, Laura Cyphers

Student Scholar Symposium Abstracts and Posters

Hispanic and Black communities have been disproportionately impacted by COVID-19-related morbidity and mortality (California Department of Public Health, 2020). Inequitable access to viral testing resources may have exacerbated these COVID-19-related racial and ethnic health disparities. For example, reports from the Los Angeles Department of Public Health revealed glaring viral testing disparities in April 2020 (early pandemic), with predominantly White communities in Los Angeles County receiving 65% more tests than Hispanic and Black communities. In response, California statewide testing was expanded for communities of color (Vann et al., 2020). To investigate access to viral testing in Los Angeles City, the current …

Seroprevalence Of Novel Coronavirus Sars-Cov-2 At A Community Hospital Emergency Department And Outpatient Laboratory In Northern Orange County, California, Jason Yamaki, Harry Peled, Sajen Mathews, David Park, Mina Firoozi, Kim Smith, Lee Nguyen

Pharmacy Faculty Articles and Research

Introduction

The severe acute respiratory syndrome related coronavirus 2 (SARS-CoV-2) has infected more than 20 million people worldwide, and the spread is most prevalent in the USA, where California had accounted over 240,000 cases in the initial 5 months of the pandemic. To estimate the number of infected persons in our community, we conducted a cross-sectional study to estimate seroprevalence of SARS-CoV-2 infection.

Methods

This cross-sectional study evaluated the presence of immunoglobulin G, antibody for SARS-CoV-2 during the time period of July 15, 2020, to July 27, 2020. Testing was done on serum samples from patients who had visited affiliated …

Using Participatory Mapping To Diagnose Upstream Determinants Of Health And Prescribe Downstream Policy-Based Interventions, Jason A. Douglas, Andrew M. Subica, Laresha Franks, Gilbert Johnson, Carlos Leon, Sandra Villanueva, Cheryl T. Grills

Health Sciences and Kinesiology Faculty Articles

Participatory mapping is a powerful methodology for working with community residents to examine social and environmental determinants of public health disparities. However, this empowering methodology has only been applied sparingly in public health research and practice, with limited examples in the literature. To address this literature gap, we 1) review participatory mapping approaches that may be applied to exploring place-based factors that affect community health, and 2) present a mixed-methods participatory geographic information systems (PGIS) examination of neighborhood assets (eg, streetlights) and challenges (eg, spaces of crime and violence) related to access to public parks in South Los Angeles, California. …

A Model To Explain Statewide Differences In Covid-19 Death Rates, James L. Doti

Economics Faculty Articles and Research

COVID-19 death rates per 100,000 vary widely across the nation. As of September 1, 2020, they range from a low of 4 in Hawaii to a high of 179 in New Jersey. Although academic research has been conducted at the county and metropolitan levels, no research has rigorously examined or identified the demographic and socioeconomic forces that explain state-level differences. This study presents an empirical model and the results of regression tests that help identify these forces and shed light on the role they play in explaining COVID-19 deaths.

A stepwise regression model we tested exhibits a high degree of …

Covid-19 Treatment Resource Disparities And Social Disadvantage In New York City, Jason A. Douglas, Andrew M. Subica

Health Sciences and Kinesiology Faculty Articles

Black and Hispanic communities in the U.S. have endured a disproportionate burden of COVID-19-related morbidity and mortality. Racial and ethnic health disparities such as these are frequently aggravated by inequitable access to healthcare resources in disadvantaged communities. Yet, no known studies have investigated disadvantaged communities' access to COVID-19-related healthcare resources. The current study accordingly examined racial and ethnic differences in (1) April 2020 COVID-19 total and positive viral test rates across 177 New York City (NYC) ZIP Code Tabulation Areas (ZCTA); and (2) November 2019–April 2020 licensed and intensive care unit (ICU) hospital bed access across 194 NYC ZCTAs. Pairwise …

Marriage and Family Therapy Faculty Articles and Research

An online, cross-sectional survey was carried out between November 2017 and January 2018 to assess fertility awareness among students attending the National Autonomous University of Mexico (UNAM) in Mexico City. A total of 371 students participated in the survey (n = 228 females, 143 males). 75% of females and 74% of males believed a woman’s fertility begins to decline markedly after age 40. Over 75% of all participants overestimated the probability of couples having a live birth after undergoing one cycle of IVF. With regard to parenting intentions, only 48% of females wished to have children compared to 59% …

Prospects For Rnai Therapy Of Covid-19, Hasan Uludağ, Kylie Parent, Hamidreza Montazeri Aliabadi, Azita Haddadi

Pharmacy Faculty Articles and Research

COVID-19 caused by the SARS-CoV-2 virus is a fast emerging disease with deadly consequences. The pulmonary system and lungs in particular are most prone to damage caused by the SARS-CoV-2 infection, which leaves a destructive footprint in the lung tissue, making it incapable of conducting its respiratory functions and resulting in severe acute respiratory disease and loss of life. There were no drug treatments or vaccines approved for SARS-CoV-2 at the onset of pandemic, necessitating an urgent need to develop effective therapeutics. To this end, the innate RNA interference (RNAi) mechanism can be employed to develop front line therapies against …

We Are Not Alone In Trying To Be Alone, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Certain diseases, like colds, tend not to stop us. A paracetamol here, an ibuprofen there, and we are on the go. That is, until we, as a species, are faced with a virus that not only spreads through social contact, but has an estimated reproductive number of 2 to 2.5 and potentially kills 3–4% of those infected (WHO, 2020). To reduce transmission probability of COVID-19, governmental agencies around the world have recommended or enforced measures to decrease social contact; early evidence suggests these measures produce the intended effect (Kucharski et al., 2020).

Comorbidity Factors Influence Covid-19 Mortality Much More Than Age, Steven Gjerstad, Andrea Molle

ESI Working Papers

This paper demonstrates that once we control for comorbidity factors, age has a minor effect on COVID-19 mortality. This has implications for the treatment of current and recovered COVID-19 patients, including health screenings of recovered COVID-19 patients, triage decisions for patients in critical care, and prioritization of vaccinations when one is developed. The coronavirus epidemic in Italy has strained hospital resources, including ICU beds and ventilators for those experiencing acute respiratory failure. Studies of COVID-19 in China [1], Italy [2], and the United States [3] show that fatality rates increase rapidly with age, especially beyond age 60. The same studies …

Love In The Time Of Covid-19: Negligence In The Nicaraguan Response, Thais P. Salazer Mather, Benjamin Gallo Marin, Giancarlo Medina Perez, Briana Christophers, Marcelo L. Paiva, Rocío Oliva, Baraa A. Hijaz, Andrea M. Prado, Mateo C. Jarquín, Katelyn Moretti, Catalina González Marqués, Alejandro Murillo, Elizabeth Tobin-Tyler

History Faculty Articles and Research

"The response of the Nicaraguan government to the coronavirus disease 2019 (COVID-19) pandemic has been perhaps the most erratic of any country in the world to date. Directly contradicting mitigation strategies recommended by WHO, President Daniel Ortega has refused to encourage any physical distancing measures. Vice President Rosario Murillo (Daniel Ortega's wife) instead called on thousands of sympathisers to congregate in street marches under the slogan 'love in the time of COVID-19'. By downplaying the danger of the pandemic and increasing the risk of community transmission in the second-poorest country in the western hemisphere, the Nicaraguan government is violating the …

Mathematics, Physics, and Computer Science Faculty Articles and Research

This newly inaugurated research database for 12-lead electrocardiogram signals was created under the auspices of Chapman University and Shaoxing People’s Hospital (Shaoxing Hospital Zhejiang University School of Medicine) and aims to enable the scientific community in conducting new studies on arrhythmia and other cardiovascular conditions. Certain types of arrhythmias, such as atrial fibrillation, have a pronounced negative impact on public health, quality of life, and medical expenditures. As a non-invasive test, long term ECG monitoring is a major and vital diagnostic tool for detecting these conditions. This practice, however, generates large amounts of data, the analysis of which requires considerable …

Using Community Pharmacy Immunization Screening Forms To Identify Potential Immunization Opportunities, Albert T. Bach, Jeffery A. Goad

Pharmacy Faculty Articles and Research

Immunization screening forms are completed for each patient that is to be vaccinated in the pharmacy. Screening forms contain demographic and health questions, which are used to determine if a patient is contraindicated to receive a vaccine. The objective is to determine if patient responses to questions on these forms can be used to identify potential vaccine indications. De-identified data was retrospectively collected from 11 community pharmacies in California and Michigan that included basic demographics, answers to immunization screening questions, and vaccine(s) administered during that visit. The Advisory Committee on Immunization Practices (ACIP) recommendations were used to forecast vaccine needs …

Decomposing Trends In Child Obesity, Ashley Wendell Kranjac, Robert L. Wagmiller

Sociology Faculty Articles and Research

We unravel the absolute level and relative prominence of two demographic processes that are relevant for childhood obesity, and that will ultimately determine the long-term course and pace of change in child obesity rates. We leverage data from the National Health and Nutrition Examination Survey to decompose change in child obesity from 1971 to 2012. We partition change into that attributable to (1) healthier, more nutritionally and economically advantaged cohorts in the population being replaced by cohorts of children who are less advantaged (between-cohort change), and (2) the health habits, nutrition, and social and economic circumstances of all cohorts of …
