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. [ABSTRACT FROM AUTHOR]

Objective. To describe the frequency, characteristics, and patient outcomes for women who accessed Emergency Medical Services (EMS) for obstetric emergencies at the ports of entry (POE) between El Paso, Texas, United States of America, and Ciudad Juárez, Chihuahua, Mexico. Methods. A descriptive study of women 12-49 years of age for whom an EMS ambulance was called to an El Paso POE location from December 2008-April 2011 was conducted. Women were identified through surveillance of EMS records. EMS and emergency department (ED) records were abstracted for all women through December 2009 and for women with an obstetric emergency through April 2011. For obstetric patients admitted to the hospital, additional prenatal and birth characteristics were collected. Frequencies and proportions were estimated for each variable; differences between residents of the United States and Mexico were tested. Results. During December 2008-December 2009, 47.6% (68/143) of women receiving EMS assistance at an El Paso POE had an obstetric emergency, nearly 20 times the proportion for Texas overall. During December 2008-April 2011, 60.1% (66/109) of obstetric patients with ED records were admitted to hospital and 52 gave birth before discharge. Preterm birth (23.1%; No. = 12), low birth weight (9.6%; No. = 5), birth in transit (7.7%; No. = 4), and postpartum hemorrhage (5.8%; No. = 3) were common; fewer than one-half the women (46.2%; No. = 24) had evidence of prenatal care. Conclusions. The high proportion of obstetric EMS transports and high prevalence of complications in this population suggest a need for binational risk reduction efforts. [ABSTRACT FROM AUTHOR]

This report describes the implementation process and functional structure of the Observatory of Security and Citizen Conviviality of the Juarez Municipality (Observatorio de Seguridad y Convivencia Ciudadanas del Municipio de Juárez) in Chihuahua, Mexico, and discusses the most relevant lessons learned and main challenges in the near future. The Observatory, created in 2008, is a joint effort of the Juarez Municipal Government, Autonomous University of Ciudad Juarez (Universidad Autónoma de Ciudad Juárez), and the Pan American Health Organization. The Observatory's main objective is to propose strategies and public policy recommendations to prevent and control violence and injuries in the Juarez Municipality. Most key federal, state, and local agencies have joined this independent autonomous citizen-based initiative, feed the databases, and benefit from the information produced by a multisectoral, multidisciplinary approach. The Observatory contributes far more than the technical data provided and its facilitating functions. The clear results obtained in such a short time-as seen in the preliminary results of the case study on road injuries from January 2009 to July 2011-- demonstrate the appropriateness of this course of action and should stimulate the creation of new observatories whenever and wherever needed. Lessons learned, as discussed here, can open the way to new endeavors, and current challenges show how much work remains to be done. [ABSTRACT FROM AUTHOR]

While U.S. health care reform will most likely reduce the overall number of uninsured Mexican-Americans, it does not address challenges related to health care coverage for undocumented Mexican immigrants, who will remain uninsured under the measures of the reform; documented low-income Mexican immigrants who have not met the five-year waiting period required for Medicaid benefits; or the growing number of retired U.S. citizens living in Mexico, who lack easy access to Medicare-supported services. This article reviews two promising binational initiatives that could help address these challenges--Salud Migrante and Medicare in Mexico; discusses their prospective applications within the context of U.S. health care reform; and identifies potential challenges to their implementation (legal, political, and regulatory), as well as the possible benefits, including coverage of uninsured Mexican immigrants, and their integration into the U.S. health care system (through Salud Migrante), and access to lower-cost Medicare-supported health care for U.S. retirees in Mexico (Medicare in Mexico).

In this era of increasing drug resistance among infectious diseases such as tuberculosis (TB), the complex population dynamics of border areas must be monitored more extensively. TB remains a major public health threat; its antimicrobial treatment is long; and the only vaccine licensed in the world, live-attenuated Mycobacterium bovis Bacille Calmette-Guérin (BCG), exhibits varying efficacy. In addition to epidemiological surveillance, the underlying determinants contributing to the health and wellbeing of populations are of key importance. Although it received heightened attention in the past, tuberculosis transmission in the United States-Mexico border area demands renewed interest. Lessons learned should be applied to similar areas around the globe. [ABSTRACT FROM AUTHOR]

Objective. The region on the United States (US) side of the US-Mexico border consists of 44 counties in four states; populations on both sides of the border have similar health problems. Healthy Border 2010: An Agenda for Improving Health on the US-Mexico Border (HB 2010) is a binational agenda of health promotion and disease prevention for individuals in the region. This study reports on the health status of the four southern Arizona border counties. Methods. Data on health indicators for Cochise, Pima, Santa Cruz, and Yuma Counties were collected from the Arizona Department of Health Services Vital Records and Statistics. Progress was calculated as a percentage made toward or away from the 2010 target. Comparisons were made between the border counties and Arizona. Results. Progress toward the HB 2010 targets varied among the border counties. All border counties made progress toward the targets with the cervical cancer, hepatitis A, and teenage birthrate objectives. Most border counties moved toward the goals for breast cancer, diabetes mortality, tuberculosis, motor vehicle crashes, infant mortality from congenital abnormalities, and prenatal care. Border counties moved away from the target with the human immunodeficiency virus and infant mortality objectives. Conclusions. Assessment of the HB 2010 objectives provided a comprehensive description of the health status of the population. Although the southern Arizona border counties have shown improvement in some areas, monitoring is still needed to identify the disparities that remain. [ABSTRACT FROM AUTHOR]

Diabetes is a serious public health problem in the border region between the United States of America and Mexico, reflecting and by some measures surpassing the extent of national diabetes burden of each country. The U.S.-Mexico Border Diabetes Prevention and Control Project, a two-phase prevalence study on type 2 diabetes and its risk factors, was conceived and developed by culturally diverse groups of people representing more than 100 government agencies and nongovernmental organizations; health care providers; and residents of 10 U.S. and Mexican border states, using a participatory approach, to address this disproportionate incidence of diabetes. This report describes the project's history, conceptualization, participatory approach, implementation, accomplishments, and challenges, and recommends a series of steps for carrying out other binational participatory projects based on lessons learned.

Objective. To estimate prevalence of type 2 diabetes (diabetes) and impaired fasting glucose (IFG) in the border region between the United States of America and Mexico, by ethnic origin and country of residence; identify risk factors associated with both conditions; and explore the extent to which these factors account for cross-border or ethnic disparities in prevalence. Methods. From April 2001 to November 2002, Phase I of the U.S.-Mexico Border Diabetes Prevention and Control Project, a prevalence study of diabetes and its risk factors, was conducted at the U.S.-Mexico border using multi-stage cluster sampling. A questionnaire was administered on diabetes (self-reported) and lifestyle and a physical examination and blood sample were obtained. A total of 4 027 adults participated in the study: 2 120 Hispanics from the Mexican side of the border and 1 437 Hispanics and 470 non-Hispanics (of whom 385 were classified as "white") from the U.S. side of the border. Results. The age-adjusted prevalence of self-reported and unrecognized diabetes in Hispanics was 15.4% (16.6% on the Mexican side of the border and 14.7% on the U.S. side). The ageadjusted prevalence of IFG was similar on both sides of the border (14.1% on the Mexican side and 13.6% on the U.S. side). Conclusions. Established risk factors for diabetes (e.g., age, obesity, and family history) were relevant and there was an inverse relationship between diabetes and education and socioeconomic level. While diabetes prevalence is high on both sides of the U.S.-Mexico border, one-third of the cases remain undiagnosed, suggesting a need for development and implementation of a public health program for prevention, diagnosis, and control of diabetes in the region.

Objective. To determine prevalence of blood pressure control, hypertension, hypertension awareness, and antihypertensive treatment among adults (≥ 18 years old) with diabetes living in the border region between the United States of America and Mexico, and to explore variation in those variables between all adults on the Mexican side of the border ("Mexicans") and three groups on the U.S. side of the border ("all U.S. adults," "U.S.-born Hispanics," and "Mexican immigrants"). Methods. Using data from Phase I (February 2001.October 2002) of the U.S.-Mexico Border Diabetes Prevention and Control Project, a prevalence study of type 2 diabetes and its risk factors, age-adjusted prevalence of hypertension-related variables was calculated for the sample (n = 682) and differences between the border groups were examined through logistic regression. Results. Less than one-third of the sample had controlled blood pressure (< 130/80 mm Hg), almost half had hypertension (≥ 140/90 mm Hg), and hypertension awareness and treatment were inadequate. After adjusting for demographics, body mass index, and access to health care, there were no differences in blood pressure control, hypertension, hypertension awareness, or treatment between Mexicans and both U.S. adults and Mexican immigrants. However, compared to Mexicans and Mexican immigrants, U.S.-born Hispanics, particularly younger individuals, had the lowest rates of blood pressure control (17.3%) and the highest rates of coexisting hypertension (54.8%). Compared to Mexicans, U.S.-born Hispanics had lower odds of controlled blood pressure (odds ratio [OR] 0.30, 95% confidence interval [CI] 0.09.0.95) and greater odds of hypertension (OR 3.75, 95% CI 1.51.9.29) and hypertension awareness (OR 6.19, 95% CI 1.46.26.15). Conclusions. Co-occurrence of diabetes and hypertension is a major public health problem among U.S.-Mexico border residents. The low rate of blood pressure control among various border groups, especially younger U.S.-born Hispanics, suggests that initiatives should aggressively target blood pressure control.

Objective. To describe and analyze, utilizing a case study approach, the U.S.- Mexico Border Diabetes Prevention and Control Project, a health research cooperation initiative incorporating the participation of federal, state, and local institutions of both countries. Methods. A model of equal representation, participation, consensus, and shared leadership was used, with the participation of more than 130 institutions. A sample of 4 020 people over 18 years of age was obtained by a random, multistage, stratified, clustered design. A questionnaire about diabetes mellitus type 2 (DM2) and health was applied. The statistical analysis took into account the design effect. Results. The prevalence of diagnosed DM2 was 14.9% (95% confidence interval [95% CI]: 12.5-17.6) and the prevalence of diagnosed DM2 adjusted by age was 19.5% (95% CI: 16.8-22.6) on the Mexican side of the border and 16.1% (IC95%: 13.5-19.2) on the U.S. border side. There were differences between the DM2 prevalence and risk factors along the border. Conclusions. The U.S.-Mexico Border Diabetes Prevention and Control Project allowed the border zone between the two countries to be considered, for the first time ever, as a unit for epidemiological research. A shared understanding among all participating institutions and entities of sociopolitical structures and procedures is required for effective border health cooperation initiatives.

Objective. To examine the relationship between access to health care and undiagnosed diabetes among the high-risk, vulnerable population in the border region between the United States of America and Mexico. Methods. Using survey and fasting plasma glucose data from Phase I of the U.S.-Mexico Border Diabetes Prevention and Control Project (February 2001 to October 2002), this epidemiological study identified 178 adults 18--64 years old with undiagnosed diabetes, 326 with diagnosed diabetes, and 2 966 without diabetes. Access to health care among that sample (n = 3 470), was assessed by type of health insurance coverage (including "none"), number of health care visits over the past year, routine pattern of health care utilization, and country of residence. Results. People with diabetes who had no insurance and no place to go for routine health care were more likely to be undiagnosed than those with insurance and a place for routine health care (odds ratio [OR] 2.6, 95% confidence interval [CI] 1.0.6.6, and OR 4.5, 95% CI 1.4.14.1, respectively). When stratified by country, the survey data showed that on the U.S. side of the border there were more people with undiagnosed diabetes if they were 1) uninsured versus the insured (28.9%, 95% CI 11.5%--46.3%, versus 9.1%, 95% CI 1.5%--16.7%, respectively) and if they 2) had made no visits or 1--3 visits to a health care facility in the past year versus had made ≥ 4 visits (40.8%, 95% CI 19.6%--62.0%, and 23.4%, 95% CI 9.9%--36.9%, respectively, versus 2.4%, 95% CI .0.9%--5.7%) (all, P < 0.05). No similar pattern was found in Mexico. Conclusions. Limited access to health care--especially not having health insurance and/or not having a place to receive routine health services--was significantly associated with undiagnosed diabetes in the U.S.-Mexico border region.

This paper reviews and discusses the main procedures and policies that need to be followed when designing and implementing a binational survey such as the United States of America (U.S.)-Mexico Border Diabetes Prevalence Study that took place between 2001 and 2002. The main objective of the survey was to determine the prevalence of diabetes in the population 18 years of age or older along U.S.-Mexico border counties and municipalities. Several political, administrative, financial, legal, and cultural issues were identified as critical factors that need to be considered when developing and implementing similar binational projects. The lack of understanding of public health practices, implementation of existing policies, legislation, and management procedures in Mexico and the United States may delay or cancel binational research, affecting the working relation of both countries. Many challenges were identified: multiagency/multifunding, ethical/budget clearances, project management, administrative procedures, laboratory procedures, cultural issues, and project communications. Binational projects are complex; they require coordination between agencies and institutions at federal, state, and local levels and between countries and need a political, administrative, bureaucratic, cultural, and language balance. Binational agencies and staff should coordinate these projects for successful implementation. [ABSTRACT FROM AUTHOR]

This study used a social-ecological framework to examine predictors of depression, diabetes self-management, and clinical indicators of health risk among Hispanics with type 2 diabetes residing in the United States (U.S.)-Mexico border region in San Diego County, California, United States of America. Important links were observed between greater social-environmental support for disease management and less depression, better diabetes self-management, and lower body mass index and serum triglyceride concentrations. Less depressive symptomatology was also related to lower hemoglobin A1c levels. Findings suggest that programs aiming to improve diabetes self-management and health outcomes in Hispanics with type 2 diabetes should consider multilevel, social, and environmental influences on health, behavior, and emotional well-being.

Objective. To examine the prevalence of smoking behaviors among adults with diabetes on the United States-Mexico border, to compare these behaviors in U.S. Hispanics and Mexicans with diabetes, and to identify explanations for group differences. Methods. Data came from the U.S.-Mexico Border Diabetes Prevention and Control Project survey (2001-2002), a stratified, multistage sample representative of the border population. The analytic sample included adults from all racial and ethnic backgrounds with diabetes (n = 665), including 333 Mexicans and 268 U.S. Hispanics. Smoking behaviors were based on self-reports. Age- and gender-specific prevalence of smoking behavior was estimated and logistic regression was used for mediation analysis of group differences. Results. One in five adults with diabetes (20.1%) in the region was a current smoker. Prevalence was higher among Mexicans (26.2%) than U.S. Hispanics (10.1%, P = 0.003); differences were not explained by sociodemographic or healthcare-related characteristics (odds ratio [OR] 3.86, 95% confidence interval [CI] 1.50-9.91, P = 0.004). Younger Mexicans with diabetes (< 55 years) were four times more likely to smoke than younger U.S. Hispanics (32.1% versus 8.1%, P < 0.001) and Mexican men with diabetes were more than twice as likely to smoke as U.S. Hispanic men (38.9% versus 15.8%, P = 0.003). Among adults with diabetes with a smoking history, 52.5% were former smokers; U.S. Hispanics were more likely to be former smokers than Mexicans with diabetes (62.6% versus 27.5%, P = 0.001). A marginally significant difference remained after adjusting for potential mediators (OR 0.42, 95% CI 0.17-1.08, P = 0.074). Conclusions. Smoking interventions should focus on Mexicans with diabetes in the border region, especially younger adults and men. Identifying sources of differences in smoking behaviors among border groups with diabetes may further inform intervention. [ABSTRACT FROM AUTHOR]

Objective. To assess and monitor the quality of care provided to Hispanics diagnosed with diabetes living in the border region between the United States of America and Mexico. Methods. From April 2001 to November 2002, Phase I of the U.S.-Mexico Border Diabetes Prevention and Control Project, a prevalence study of type 2 diabetes and its risk factors, was conducted along the U.S.-Mexico border using two-stage cluster sampling of towns and households within towns. A questionnaire was administered on diabetes (self-reported) and lifestyle and a physical examination and blood sample were obtained. Of the 4 027 study participants, 521 (13.0%) reported receiving a pre-study diagnosis of diabetes. Of those, 466 were of Hispanic origin (226 on the Mexican side of the border and 240 on the U.S. side). Results. Results indicated 42.1% of Hispanics on the U.S. side of the border (95% confidence interval [CI] 35.8%-48.6%) and 37.6% of Hispanics on the Mexican side (95% CI 31.3%-44.3%) had controlled diabetes (defined as glycosylated hemoglobin A1c < 7.0 %), and only one (on the Mexican side of the border) received optimal diabetes care, defined according to international criteria for systolic blood pressure and body mass index as well as health provider provision of yearly examinations of foot and eyes as preventive care measures for early detection of diabetes complications. Conclusions. Adult Hispanics diagnosed with diabetes and living on the U.S.-Mexico border region are not receiving adequate diabetes-related care, and health care professionals are not following international recommendations for providing that care. To improve diabetes control in the region, health care providers must become more aware of the effect of education and culture on diabetes self-care as well as the provision of preventative measures by health care professionals.

Objective. To compare the prevalence of undiagnosed diabetes among populations with diabetes living on the United States (U.S.).Mexico border, examine explanations for differences between groups, and investigate differences in metabolic outcomes by diagnosis status. Methods. Data come from the U.S..Mexico Border Diabetes Prevention and Control Project survey (2001.2002), which used a stratified, multistage design. The sample included 603 adults (18 years or older) with diabetes. Undiagnosed diabetes was defined as a fasting plasma glucose (FPG) value of ≥ 126 mg/dL and no report of diagnosis. Logistic regression was used to compare the odds of being undiagnosed among border populations with diabetes. Metabolic outcomes included FPG, glycosylated hemoglobin, and mean arterial blood pressure. Results. One in four adults with diabetes (25.9%) living on the U.S..Mexico border was undiagnosed. Mexicans (43.8%) and Mexican immigrants (39.0%) with diabetes were significantly more likely to be undiagnosed than were U.S.-born Hispanics (15.0%; P < 0.05 for either comparison) or non-Hispanic whites (6.6%; P < 0.001 for either comparison). Mexicans were more likely to be undiagnosed than were all U.S. adults (14.7%; P < 0.001) with diabetes. Significant differences in the likelihood of being undiagnosed remained between all groups with diabetes after adjustment for sociodemographic and healthcare-related covariates, with the exception of that between Mexicans and U.S.-born Hispanics. Worse metabolic control and potentially greater benefits of diagnosis for control were observed for Mexicans in particular compared with U.S. groups with undiagnosed diabetes. Conclusions. Efforts to improve diabetes diagnosis should concentrate on Mexican and Mexican immigrant populations on the U.S..Mexico border. [ABSTRACT FROM AUTHOR]

Objective. To explore the relationship between acculturation and healthy lifestyle habits in the largely Hispanic populations living in underserved communities in the United States of America along the U.S.-Mexico border. Methods. A cross-sectional study was conducted from April 2006 to June 2008 using survey data from the Alliance for a Healthy Border, a program designed to reduce health disparities in the U.S.-Mexico border region by funding nutrition and physical activity education programs at 12 federally qualified community health centers in Arizona, California, New Mexico, and Texas. The survey included questions on acculturation, diet, exercise, and demographic factors and was completed by 2 381 Alliance program participants, of whom 95.3% were Hispanic and 45.4% were under the U.S. poverty level for 2007. Chi-square (χ2) and Student's t tests were used for bivariate comparisons between acculturation and dietary and physical activity measures. Linear regression and binary logistic regression were used to control for factors associated with nutrition and exercise. Results. Based on univariate tests and confirmed by regression analysis controlling for sociodemographic and health variables, less acculturated survey respondents reported a significantly higher frequency of fruit and vegetable consumption and healthier dietary habits than those who were more acculturated. Adjusted binary logistic regression confirmed that individuals with low language acculturation were less likely to engage in physical activity than those with moderate to high acculturation (odds ratio 0.75, 95% confidence interval 0.59-0.95). Conclusions. Findings confirmed an association between acculturation and healthy lifestyle habits and supported the hypothesis that acculturation in border community populations tends to decrease the practice of some healthy dietary habits while increasing exposure to and awareness of the importance of other healthy behaviors.
