Globalization and health at the United States-Mexico border

Cross-border healthcare: A review and applicability to North America during COVID-19

Cross-border healthcare is an international agreement for the provision of out of country healthcare for citizens of partnered countries. The European Union (EU) has established itself as a world leader in cross-border healthcare. During the Coronavirus disease of 2019 (COVID-19) pandemic, the EU used this system to maximize utilization of resources. Countries with capacity accepted critically ill patients from overwhelmed nations, borders remained open to healthcare workers and those seeking medical care in an effort to share the burden of this pandemic. Significant research into the challenges and successes of cross-border healthcare was completed prior to COVID-19, which demonstrated significant benefit for patients. In North America, the response to the COVID-19 crisis has been more isolationist. The Canada-United States border has been closed and bans placed on healthcare workers crossing the border for work. Prior to COVID-19, cross-border healthcare was rare in North America despite its need. We reviewed the literature surrounding cross-border healthcare in the EU, as well as the need for a similar system in North America. We found the EU cross-border healthcare agreements are generally mutually beneficial for participating countries. The North American literature suggested a cross-border healthcare system is feasible. A number of challenges could be identified based on the EU experience. A prior agreement may have been beneficial during the COVID-19 crisis as many Canadian healthcare institutions-maintained capacity to accept critically ill patients.

"We go to Tijuana to double check everything": The contemporaneous use of health services in the U.S. and Mexico by Mexican immigrants in a border region

Research in 2009 showed that hundreds of thousands of Mexican immigrants in the U.S. return to Mexico for healthcare annually. Existing studies on the cross-border healthcare behaviors of this group are dominated by two related questions: 1) Why do Mexican immigrants go to Mexico for care? and 2) What are individual-level predictors of seeking care in Mexico? While this research has identified people's motivations for crossing the border for care and key characteristics associated with this behavior, it has underemphasized an important feature of cross-border healthcare seeking, namely that some immigrants contemporaneously use healthcare in the U.S. and Mexico. Drawing on qualitative interviews with Mexican immigrants in San Diego, CA, located on the U.S.-Mexico border, I show that for some, seeking care in Mexico is a way to supplement the care they receive in the U.S. In this region, some people combine care in the two countries in attempts to achieve what they believe to be optimal care results. Their cross-border behaviors include seeking care in the U.S. for a health condition and, if dissatisfied, going to Mexico for care; getting care in the U.S for certain health problems and Mexico for others; going to Mexico for specialist care when their U.S. doctors will not refer them to specialists; and going to Mexico for pharmaceuticals their U.S. doctors will not prescribe. For these individuals, proximity to the border changes the meanings and behaviors associated with being a patient, in that it enables them to be more actively engaged in their care. At the same time, findings raise questions about the quality of care that results from mixing care in the two countries. These findings suggest a need to understand cross-border healthcare seeking among some border residents as embedded in a larger repertoire of healthcare practices.

Surveillance of Aedes aegypti indoors and outdoors using Autocidal Gravid Ovitraps in South Texas during local transmission of Zika virus, 2016 to 2018

The yellow fever mosquito, Aedes aegypti, has facilitated the re-emergence of dengue virus (DENV) and emergence of chikungunya virus (CHIKV) and Zika virus (ZIKV) in the Americas and the Caribbean. The recent transmission of these arboviruses in the continental United States has been limited, to date, to South Florida and South Texas despite Ae. aegypti occurring over a much larger geographical region within the country. The main goal of our study was to provide the first long term longitudinal study of Ae. aegypti and enhance the knowledge about the indoor and outdoor relative abundance of Ae. aegypti as a proxy for mosquito-human contact in South Texas, a region of the United States that is at high risk for mosquito-borne virus transmission. Here, the relative abundance of indoors and outdoors mosquitoes of households in eight different communities was described. Surveillance was done weekly from September 2016 to April 2018 using the CDC Autocidal Gravid Ovitraps in low- and middle-income communities. A total of 69 houses were included in this survey among which 36 were in the low-income communities (n = 11 for Donna, n = 15 for Progresso, n = 5 for Mesquite, n = 5 for Chapa) and 33 in middle-income communities (n = 9 for La Feria, n = 8 for Weslaco, n = 11 for McAllen, and n = 5 for Rio Rico). Overall, Ae. aegypti was the dominant species (59.2% of collections, n = 7255) followed by Culex spp. mosquitoes (27.3% of collections, n = 3350). Furthermore, we demonstrated for Ae. aegypti that 1) outdoor relative abundance was higher compared to indoor relative abundance, 2) low-income communities were associated with an increase in mosquito relative abundance indoors when compared to middle-income communities, 3) no difference was observed in the number of mosquitoes collected outdoors between low-income and middle-income communities, and 4) warmer months were positively correlated with outdoor relative abundance whereas no seasonality was observed in the relative abundance of mosquitoes indoors. Additionally, Ae. aegypti mosquitoes collected in South Texas were tested using a specific ZIKV/CHIKV multiplex real-time PCR assay, however, none of the mosquitoes tested positive. Our data highlights the occurrence of mosquitoes indoors in the continental United States and that adults are collected nearly every week of the calendar year. These mosquito data, obtained concurrently with local ZIKV transmission of 10 locally acquired cases in nearby communities, represent a baseline for future studies in the Lower Rio Grande Valley (LRGV) including vector control interventions relying on the oviposition behavior to reduce mosquito populations and pathogen transmission.

The Border Health Consortium of the Californias-Forming a Binational (California-Baja California) Entity to Address the Health of a Border Region: A Case Study

The California–Baja California border region is one of the most frequently traversed areas in the world with a shared population, environment, and health concerns. The Border Health Consortium of the Californias (the “Consortium”) was formed in 2013 to bring together leadership working in the areas of public health, health care, academia, government, and the non-profit sector, with the goal of aligning efforts to improve health outcomes in the region. The Consortium utilizes a Collective Impact framework which supports a shared vision for a healthy border region, mutually reinforcing activities among member organizations and work groups, and a binational executive committee that ensures continuous communication and progress toward meeting its goals. The Consortium is comprised of four binational work groups which address human immunodeficiency virus, tuberculosis, obesity, and mental health, all mutual priorities in the border region. The Consortium holds two general binational meetings each year alternating between California and Baja California. The work groups meet regularly to share information, resources and provide binational training opportunities. Since inception, the Consortium has been successful in strengthening binational communication, coordination, and collaboration by providing an opportunity for individuals to meet one another, learn about each other systems, and foster meaningful relationships. With binational leadership support and commitment, the Consortium could certainly be replicated in other border jurisdictions both nationally and internationally. The present article describes the background, methodology, accomplishments, challenges, and lessons learned in forming the Consortium.

Best practices for community gardening in a US-Mexico border community

Minority communities such as those on the US-Mexico border are placed at disproportionate high risk for child and adult obesity, diabetes and cardiovascular diseases. A built environment characterized by an arid desert climate, lack of access to healthy foods, barriers to increasing physical activity, cultural and community norms which deter healthy eating and sustainable food production, shape obesity-related health disparities in these communities. Three pilot community gardens (implemented by two local governmental organizations and one community-based organization) were funded through the local Healthy Eating Active Living (HEAL) initiative in El Paso, Texas, and Las Cruces and Anthony, New Mexico (US-MX border communities with high obesity rates) in order to encourage healthy lifestyles among families in the region. A mixed-methods evaluation (n = 223) examined the implementation process, immediate outcomes and best practices of implementing and sustaining community gardens in these minority binational communities. In addition to nutrition-related outcomes, the potential for psychosocial outcomes from participating in community and school garden projects were observed. The best practices in relation to (i) assessing community norms related to growing food, (ii) increasing access to land and water for community/school gardening and (iii) enhancing social support for gardening are discussed. The implications of these best practices for obesity prevention and implementing community gardens in a minority US-MX border community characterized by cultural, geographical and socioeconomic barriers are examined.

Impacting Binational Health through Leadership Development: A Program Evaluation of the Leaders across Borders Program, 2010-2014

Background

Workforce and leadership development is imperative for the advancement of public health along the U.S./Mexico border. The Leaders across borders (LaB) program aims to train the public health and health-care workforce of the border region. The LaB is a 6-month intensive leadership development program, which offers training in various areas of public health. Program curriculum topics include: leadership, border health epidemiology, health diplomacy, border public policies, and conflict resolution.

Methods

This article describes the LaB program evaluation outcomes across four LaB cohort graduates between 2010 and 2014. LaB graduates received an invitation to participate via email in an online questionnaire. Eighty-five percent (n = 34) of evaluation participants indicated an improvement in the level of binationality since participating in the LaB program. Identified themes in the evaluation results included increased binational collaborations and partnerships across multidisciplinary organizations that work towards improving the health status of border communities. Approximately 93% (n = 37) of the LaB samples were interested in participating in future binational projects while 80% (n = 32) indicated interest in the proposal of other binational initiatives. Participants expressed feelings of gratitude from employers who supported their participation and successful completion of LaB.

Discussion

Programs such as LaB are important in providing professional development and education to a health-care workforce along the U.S./Mexico border that is dedicated to positively impacting the health outcomes of vulnerable populations residing in this region.

The United States-Mexico border environmental public health: the challenges of working with two systems

This report shares the challenges and opportunities encountered by a binational project that examined the availability of environmental and public health information for the United States-Mexico border area. The researchers interviewed numerous national and binational agencies on both sides of the border, endeavoring to develop a framework to advance the knowledge of academic and public health professionals in the area of environmental border health. However, the lack of standardized indicators and metrics in both countries validates the emergent need to establish a viable framework for the collection, analysis, and dissemination of environmental information. Recommendations for next steps are included.

Socio-ecological influences on health-care access and navigation among persons of Mexican descent living on the U.S./Mexico border

The study reported here examines factors influencing decision-making concerning health care access and navigation among persons of Mexican origin living along the U.S./Mexico border. Specifically, the study examined how persons with limited financial resources accessed these two systems. Seven focus groups were held with 52 low income Mexican American people aged 18-65 years. Transcripts were analyzed to identify themes in Atlasti 5.0 software and the theory used included a socio-ecological framework and complemented by constructed from the Social Cognitive Theory. We found that in addition to a lack of insurance and financial resources to pay for health care; fear, embarrassment and denial associated with a diagnosis of illness; poor medical personnel interactions, and desire for quality but streamlined health care also influenced decision making. This theory-based study raises important issues if health care is to improve the health and welfare of disadvantaged populations and points to the need for greater focus on medical homes and prevention and early intervention approaches.

The mediation of trust in country-of-origin effects across countries

Purpose

– This paper aims to investigate if trust plays a mediating role on the country-of-origin (COO) brand reputation and consumer animosity effects in determining consumers’ purchase intentions in both emerging and developed markets.

Design/methodology/approach

– The paper opted for the structure equation modelling methodology to analyse data collected from 476 Spanish and Mexican car owners who evaluate American automobiles.

Findings

– The results show that in the emerging market economy, the COO's brand reputation influences trust and purchase intention more than in the mature market. Also, the results show that although trust plays an important role in different markets because it mediates the effect of COO's brand reputation on consumers’ purchase intention in both emerging and mature economies, it does not mediate the effect of animosity on purchase intention in the analysed developed economy.

Research limitations/implications

– The chosen category product presents the shortcoming of being of a hybrid nature regarding their manufacturing origin and research results may not be generalizable since we consider one product of one COO.

Practical implications

– COO's brand reputation is a key trigger of trust, and can substitute absent regulatory institutional elements, especially in emerging markets. In emerging markets, animosity could play an important role in explaining the rejection of foreign products, but the increase of trust could mitigate its negative effect on purchase intention.

Originality/value

– This study distinguishes the mediating role of trust between different interrelated COO variables and consumers’ purchase intentions in two different national contexts, and offers evidence that good COO's brand reputation building is crucial for international marketing success.

Cross-border health care utilization among the Hispanic population in the United States: implications for closing the health care access gap

OBJECTIVES

To examine predictors of health care service utilization in Mexico or any other country in Latin America among the U.S. Hispanic population.

METHODS

This study used data from the 2007 Pew Hispanic Healthcare Survey, a nationally representative survey of 4013 Hispanic adults. Using the Behavioral Model of Health Service Use (BMHSU) model, we examined three levels of predictive factors: (1) predisposing characteristics (e.g., language proficiency), (2) enabling resources (e.g., health insurance status), and (3) need (e.g., self-perceived health status). Multivariate logistic regression analyses were conducted to predict odds of seeking health care services in Mexico or any other country in Latin America.

RESULTS

As hypothesized, lack of continuous health insurance coverage, perceived lack of quality health care, and low English proficiency increased the likelihood of seeking health care in Mexico or any other Latin American country among US Hispanic adults. Self-reported health status and usual source of care, however, were not significant predictors.

CONCLUSIONS

Hispanic immigrants face critical access gaps to health care in the United States. Implications for closing the access gap for this population are discussed within the context of health care system reform and immigration reform in the United States.

Tertius Iungens Brokerage and Transnational Intersectoral Cooperation

Tertius iungens brokerage is unique within the dominant brokerage conceptualizations in sociology. While most brokerage research finds that brokers reap rewards from mediating relationships in ways that keep actors apart, iungens research finds that brokers can have an interest in joining previously disconnected actors and sustaining these relationships. This paper expands the explanatory potential of iungens brokerage by building a multidimensional theoretical framework that explains transnational connecting processes, generating insights beyond the traditional focus on network structures into the under-researched area of brokerage across institutions. The paper synthesizes streams of brokerage research that have developed in relative isolation from each other to elucidate how organizational brokers and their staffs create transnational structural and cognitive connections that draw actors together into intersectoral networks that cross two or more nationally organized regulatory regimes and cultural systems in order to cooperate on complex public good problems. The paper’s case study of public health cooperation on the United States–Mexico border advances the argument that iungens brokerage is necessary to counter the divisive effects that state institutions tend to exert on transnational networks over time.

U.S.-Mexico cross-border workforce training needs: survey implementation

Background:

Since the tragic events experienced on September 11, 2001, and other recent events such as the hurricane devastation in the southeastern parts of the country and the emergent H1N1season, the need for a competent public health workforce has become vitally important for securing and protecting the greater population.

Objective: The primary objective of the study was to assess the training needs of the U.S. Mexico border states public health workforce.

Methods:

The Arizona Center for Public Health Preparedness of the Mel and Enid Zuckerman College of Public Health at The University of Arizona implemented a border-wide needs assessment. The online survey was designed to assess and prioritize core public health competencies as well as bioterrorism, infectious disease, and border/binational training needs.

Results:

Approximately 80% of the respondents were employed by agencies that serve both rural and urban communities. Respondents listed 23 different functional roles that best describe their positions. Approximately 35% of the respondents were primarily employed by state health departments, twenty-seven percent (30%) of the survey participants reported working at the local level, and 19% indicated they worked in other government settings (e.g. community health centers and other non-governmental organizations). Of the 163 survey participants, a minority reported that they felt they were well prepared in the Core Bioterrorism competencies. The sections on Border Competency, Surveillance/Epidemiology, Communications/Media Relations and Cultural Responsiveness, did not generate a rating of 70% or greater on the importance level of survey participants.

Conclusions:

The study provided the opportunity to examine the issues of public health emergency preparedness within the framework of the border as a region addressing both unique needs and context. The most salient findings highlight the need to enhance the border competency skills of individuals whose roles include a special focus on emergency preparedness and response along the US-Mexico border.

Health insurance for undocumented immigrants: opportunities and barriers on the Mexican side of the US border

OBJECTIVE

This article aims to identify opportunities, barriers and challenges in Mexico's policy networks for the development of healthcare programs for undocumented migrants in the USA and their families.

METHODS

We used policy analysis, in-depth interviews and a case study. Key stakeholders at the federal, state and municipal levels in one major migrant-sending state were interviewed. We also conducted an in-depth case study of one community to obtain the perceptions of local health workers, migrant families and local nongovernmental organizations.

RESULTS

Findings identified opportunities and barriers involving the stakeholders, institutions, social interactions and types of relationships necessary for further progress on binational policies. There was wide interest in creating binational health insurance with different degrees of potential involvement by political actors and variation in local actors' willingness to be covered by some type of health insurance scheme.

CONCLUSIONS

The use of the opportunities to overcome barriers depends on the identification of high, medium or low interaction among key stakeholders, integration of coalitions and negotiating skills of all stakeholders involved.

Heading south: why Mexican immigrants in California seek health services in Mexico

OBJECTIVES

To Identify factors that explain why some Mexican immigrants in California use health services in Mexico.

METHODS

California Health Interview Survey 2001 data were analyzed for medical care, dental care, and/or prescription drug purchases in Mexico in the previous year. Logistic regressions estimated the effect on use of need, availability, accessibility, and acceptability among immigrants from Mexico.

RESULTS

An estimated 952,000 California adults used medical, dental, or prescription services in Mexico during the past year, of whom 488,000 were Mexican immigrants. Long-stay Mexican immigrants had the highest rate (15%), followed by short-stay Mexican immigrants (11.5%), US-born Mexican Americans (5.4%), and US-born nonLatino whites (2.1%). Predictors of use by immigrants included need, no insurance, delay seeking care, more recent immigration, limited English, and nonphysician provider use. Living closer to the border increased use, although half of immigrants seeking services lived more than 120 miles from the border. Mexican immigrants with long stays in the US have a somewhat different pattern of predictors from those with short stays.

CONCLUSIONS

Mexican immigrants are the most likely to seek medical, dental, and prescription services in Mexico. A large number, but small percentages, of US-born nonLatino whites purchase prescription drugs there. Although proximity facilitates use, access and acceptability barriers in the US medical care system encourage immigrants to seek care in Mexico who would be helped by expanded binational health insurance.

Health insurance and access to care for families with young children in California, 2001-2005: differences by immigration status

OBJECTIVES

To examine differences and trends in health insurance coverage and access to care for California families by immigration status.

METHODS

Cross-sectional data on 37,236 families with young children <18 years of age from the 2001, 2003 and 2005 California Health Interview Survey are used to assess trends in health insurance and access to care for children and their parents by four immigration dyads: (1) both are Citizens; (2) child is a legal resident/citizen, and parent is legal resident (Documented); (3) child is a citizen, and parent is undocumented (Mixed); and (4) both are Undocumented.

RESULTS

Before and after adjustment for covariates, only children in Undocumented dyads were less likely than Citizen dyads to have insurance (OR = 0.20, CI: 0.16-0.26) and all three measures of access: physician visits (OR = 0.69, CI: 0.52-0.91), dental visits (OR = 0.47, CI: 0.35-0.63), and a regular source of care (OR = 0.51, CI: 0.37-0.69). Parents in all non-Citizen dyads had poorer access than Citizen dyads across all measures, with the exception of dental visits and a regular source for parents in Documented dyads. Children of all dyads except Citizens were more likely to be insured in 2005 vs. 2001. The largest gain was for undocumented dyad children with 2.77 times higher odds (CI: 1.62-4.75) of being insured in 2005 vs. 2001. All children dyads except Mixed were also more likely to have a physician visit. For parents, there was only a decrease in insurance coverage for Citizen dyads (OR = 0.79, CI: 0.67-0.93) and few changes in access. Conclusions While there were relatively few disparities and some improvements in insurance coverage and access for children in California (except for undocumented children), concomitant changes for parents were not observed. Without attention to the family in health care reforms, disparities may not fully resolve for children and may continue or even increase for parents.

Language and use of cancer screening services among border and non-border Hispanic Texas women

OBJECTIVES

Compared to other groups, Mexican American women screen less frequently for cervical and breast cancer. The most significant barriers reported by previous researchers include not having a usual source of care, lacking health insurance and English-language difficulties. In this paper we document and examine the factors associated with disparities in cancer screening between border and non-border residents by language of interview (Spanish or English) among Texas Hispanic women. We hypothesize that, controlling for socioeconomic and demographic characteristics, border residents are more likely to utilize screening services than non-border residents because of the greater presence of bilingual services in border counties.

DESIGN

We follow the framework of the Behavioral Model for Vulnerable Populations proposed by Gelberg et al. (Health Services Research, vol. 34, no. 6, pp. 1273-1302, 2000). This model conceptualizes use of health care as an outcome of the interplay of predisposing, enabling and need factors and recognizes that vulnerable groups face additional barriers to health care utilization. Data come from the 2000, 2002 and 2004 Texas Behavioral Risk Factor Surveillance surveys.

RESULTS

Group differences in cancer screenings are explained largely by socioeconomic characteristics and structural barriers to access. The significance of language of interview and of border residence disappear after controlling for factors such as health insurance, income and a usual source of care.

CONCLUSION

Women who selected to be interviewed in Spanish were less likely to report age-appropriate cancer examinations, health insurance and a regular health care provider than those who selected to be interviewed in English. Disparities in cancer screenings among vulnerable Hispanic populations could be reduced by promoting the establishment of a regular health care provider.

Managing US-Mexico "border health": an organizational field approach

During World War II Mexican and US health professionals and organizations constructed a transnational organizational field to manage the border's public health problems. Despite barriers to inter-organizational cooperation, including disparate administrative structures and North-South stratification, the field's transnational approach to health on the border has continued for 60 years. Using archival data to track changes in the number and types of organizations, this article argues that the field practitioners call "border health" reconfigured during the North American Free Trade Association (NAFTA) decade from an era of loosely organized professionals to a specialized bureaucracies era. This change brought new vitality to border health, with transnational ties increasing and diversifying, but has not weakened entrenched cross-border inequalities. The organizational history of the US-Mexico border health field demonstrates how macro-politics and inter-organizational stratification shape transnational public health problems.

The In-Home Environment and Household Health: A Cross-Sectional Study of Informal Urban Settlements in Northern México

People living in poverty make up nearly half of the global population and a large proportion of these individuals inhabit cities, living in informal settlements. However, only limited research on in-home environmental exposures and the associated health effects in these communities is available. This research investigates the home environment in unplanned settlements of a rapidly growing city on the U.S.-México border and its impact on the health of households with children under 12 years of age. A cross-sectional design was used to assess household exposures and health outcomes at the household level. A total of 202 households were selected from two informal settlements in the peri-urban region of Ciudad Juárez, México. The following variables were significantly associated with the report of at least one household member experiencing a health outcome in a two week period. Allergies were positively associated with insecticide use inside the home (adjusted Relative Odds (RO), 2.71; 95% confidence interval (CI), 1.2-6.3). Respiratory problems were associated with households using a wood burning stove vs. a gas stove (adjusted RO, 5.64; 95% CI, 1.1-27.9). Diarrhea was negatively associated with presence of a flush toilet in the home (adjusted RO, 0.22; 95% CI,0.1-0.6). Finally, eye irritations were positively associated with indoor tobacco smoke (adjusted RO, 2.23; 95% CI, 1.1-4.5). This research highlights exposures associated with poor living conditions in informal settlements and their associations with detrimental effects on health. More efforts should be made to understand the dynamics of poor urban environments including the health effects of exposures linked with poor housing conditions.

Global trade and public health

Global trade and international trade agreements have transformed the capacity of governments to monitor and to protect public health, to regulate occupational and environmental health conditions and food products, and to ensure affordable access to medications. Proposals under negotiation for the World Trade Organization's General Agreement on Trade in Services (GATS) and the regional Free Trade Area of the Americas (FTAA) agreement cover a wide range of health services, health facilities, clinician licensing, water and sanitation services, and tobacco and alcohol distribution services. Public health professionals and organizations rarely participate in trade negotiations or in resolution of trade disputes. The linkages among global trade, international trade agreements, and public health deserve more attention than they have received to date.
