Community Health Workers: An Untapped Resource to Promote Genomic Literacy.

Poor understanding of gene-environment contributors to health conditions can lead the public to misinterpretations that overemphasize genetics as determinants of health. The present commentary calls for engaging the national community health worker (CHW) workforce to use community elicitation methods such as mental models approaches as a means to enhance the public's literacy regarding genetic and environmental or genomic contributions to health. We discuss three needs related to genomic literacy and suggest how CHWs are uniquely positioned to address these needs among diverse target audiences. We conclude by offering directions for the future of CHWs working to build genomic literacy.

Promotoras Can Facilitate Use of Recreational Community Resources: The Mi Corazón Mi Comunidad Cohort Study.

INTRODUCTION: Limited research has documented interventions aimed at promoting use of existing recreational community resources among underserved populations. This study (HEART [Health Education Awareness Research Team] Phase 2) reports findings of an intervention (Mi Corazón Mi Comunidad) where community health workers facilitated use of diet and exercise programming at local recreational facilities among Mexican American border residents. The aim was to evaluate overall attendance rates and to assess which factors predicted higher attendance. METHOD: The design was a cohort study. From 2009 to 2013, a total of 753 participants were recruited across 5 consecutive cohorts. The intervention consisted of organized physical activity and nutrition programming at parks and recreational facilities and a free YWCA membership. Attendance at all activities was objectively recorded. Regression analyses were used to evaluate whether demographic factors, health status, and health beliefs were associated with attendance. Results Participants included mostly females at high risk for cardiovascular disease (72.4% were overweight/obese and 64% were [pre-]hypertensive). A total of 83.6% of participants attended at least one session. On average, total attendance was 21.6 sessions (range: 19.1-25.2 sessions between the different cohorts), including 16.4 physical activity and 5.2 nutrition sessions. Females (p = .003) and older participants (p < .001) attended more sessions. Participants low in acculturation (vs. high) attended on average seven more sessions (p = .003). Greater self-efficacy (p < .001), perceived benefits (p = .038), and healthy intentions (p = .024) were associated with higher attendance. Conclusions The intervention was successful in promoting use of recreational facilities among border residents at high risk for cardiovascular disease. Findings were similar across five different cohorts.

Psychological, cultural and neuroendocrine profiles of risk for preterm birth.

BACKGROUND: Preterm birth remains a major obstetrical problem and identification of risk factors for preterm birth continues to be a priority in providing adequate care. Therefore, the purpose of this study was to elucidate risk profiles for preterm birth using psychological, cultural and neuroendocrine measures. METHODS: From a cross sectional study of 515 Mexican American pregnant women at 22-24 weeks gestation, a latent profile analysis of risk for preterm birth using structural equation modeling (SEM) was conducted. We determined accurate gestational age at delivery from the prenatal record and early ultrasounds. We also obtained demographic and prenatal data off of the chart, particularly for infections, obstetrical history, and medications. We measured depression (Beck Depression Inventory), mastery (Mastery scale), coping (The Brief Cope), and acculturation (Multidimensional Acculturation Scale) with reliable and valid instruments. We obtained maternal whole blood and separated it into plasma for radioimmunoassay of Corticotrophin Releasing Hormone (CRH). Delivery data was obtained from hospital medical records. RESULTS: Using a latent profile analysis, three psychological risk profiles were identified. The "low risk" profile had a 7.7% preterm birth rate. The "moderate risk" profile had a 12% preterm birth rate. The "highest risk" profile had a 15.85% preterm birth rate. The highest risk profile had double the percentage of total infections compared to the low risk profile. High CRH levels were present in the moderate and highest risk profiles. CONCLUSION: These risk profiles may provide a basis for screening for Mexican American women to predict risk of preterm birth, particularly after they are further validated in a prospective cohort study. Future research might include use of such an identified risk profile with targeted interventions tailored to the Hispanic culture.

Binational utilization and barriers to care among Mexican American border residents with diabetes.

OBJECTIVE: To assess whether U.S.-Mexico border residents with diabetes 1) experience greater barriers to medical care in the United States of America versus Mexico and 2) are more likely to seek care and medication in Mexico compared to border residents without diabetes. METHODS: A stratified two-stage randomized cross-sectional health survey was conducted in 2009 - 2010 among 1 002 Mexican American households. RESULTS: Diabetes rates were high (15.4%). Of those that had diabetes, most (86%) reported comorbidities. Compared to participants without diabetes, participants with diabetes had slightly greater difficulty paying US$ 25 (P = 0.002) or US$ 100 (P = 0.016) for medical care, and experienced greater transportation and language barriers (P = 0.011 and 0.014 respectively) to care in the United States, but were more likely to have a person/place to go for medical care and receive screenings. About one quarter of participants sought care or medications in Mexico. Younger age and having lived in Mexico were associated with seeking care in Mexico, but having diabetes was not. Multiple financial barriers were independently associated with approximately threefold-increased odds of going to Mexico for medical care or medication. Language barriers were associated with seeking care in Mexico. Being confused about arrangements for medical care and the perception of not always being treated with respect by medical care providers in the United States were both associated with seeking care and medication in Mexico (odds ratios ranging from 1.70 - 2.76). CONCLUSIONS: Reporting modifiable barriers to medical care was common among all participants and slightly more common among 1) those with diabetes and 2) those who sought care in Mexico. However, these are statistically independent phenomena; persons with diabetes were not more likely to use services in Mexico. Each set of issues (barriers facing those with diabetes, barriers related to use of services in Mexico) may occur side by side, and both present opportunities for improving access to care and disease management.

Ethnic Pride and Cardiovascular Health Among Mexican American Adults Along the U.S.-Mexico Border.

This study addressed the association between items from the General Acculturation Index (GAI) and cardiovascular health. Specifically, we assessed whether ethnic pride was associated with health outcomes after controlling for items regarding language, place where the childhood was spent and ethnic interaction. The study was a cross sectional analysis of demographic and clinical data from a border population of Mexican American adults (n=316) at risk for cardiovascular disease (CVD). Outcomes included smoking and diabetes status, Framingham risk, and metabolic syndrome. Ethnic pride was associated with lower diabetes prevalence, lower Framingham risk, and fewer risk factors for metabolic syndrome, but was not associated with smoking status. Ethnic pride was not associated with the other acculturation items of the GAI. Among an at-risk border population, ethnic pride functioned independently of other acculturation indicators. Ethnic pride may act as a protective factor for diabetes, metabolic syndrome and CVD risk status.

A promotores de salud intervention to reduce cardiovascular disease risk in a high-risk Hispanic border population, 2005-2008.

INTRODUCTION: The high prevalence of cardiovascular disease (CVD) in the Hispanic population of the United States, together with low rates of health insurance coverage, suggest a potential cardiovascular health crisis. The objective of Project HEART (Health Education Awareness Research Team) was to promote behavior changes to decrease CVD risk factors in a high-risk Hispanic border population. METHODS: Project HEART took place from 2005 through 2008 as a randomized community trial with a community-based participatory research framework using promotores de salud (community health workers). A total of 328 participants with at least 1 CVD risk factor were selected by randomizing 10 US Census tracts in El Paso, Texas, to either the experimental or the control group. The experimental group (n = 192) was assigned to a series of 8 health classes using the Su Corazón, Su Vida curriculum. After 2 months of educational sessions, the group was followed for 2 months. The control group (n = 136) was given basic educational materials at baseline, and no other intervention was used. Main outcomes of interest included changes in health behaviors and clinical measures. RESULTS: Participants in the experimental group showed more awareness of CVD risk factors, more confidence in the control of these factors, and improved dietary habits (ie, lower salt and cholesterol intake, better weight-control practices) compared with the control group. Total cholesterol was 3% lower in the experimental than in the control participants, and nonhigh-density lipoprotein cholesterol and low-density lipoprotein cholesterol were both 5% lower. CONCLUSION: The HEART trial suggests that community health education using promotores de salud is a viable strategy for CVD risk reduction in a Hispanic border community.

Correlates of tobacco cessation counseling among Hispanic physicians in the US: a cross-sectional survey study.

BACKGROUND: Physician advice is an important motivator for attempting to stop smoking. However, physicians' lack of intervention with smokers has only modestly improved in the last decade. Although the literature includes extensive research in the area of the smoking intervention practices of clinicians, few studies have focused on Hispanic physicians. The purpose of this study was to explore the correlates of tobacco cessation counseling practices among Hispanic physicians in the US. METHODS: Data were collected through a validated survey instrument among a cross-sectional sample of self-reported Hispanic physicians practicing in New Mexico, and who were members of the New Mexico Hispanic Medical Society in the year 2001. Domains of interest included counseling practices, self-efficacy, attitudes/responsibility, and knowledge/skills. Returned surveys were analyzed to obtain frequencies and descriptive statistics for each survey item. Other analyses included: bivariate Pearson's correlation, factorial ANOVAs, and multiple linear regressions. RESULTS: Respondents (n = 45) reported a low level of compliance with tobacco control guidelines and recommendations. Results indicate that physicians' familiarity with standard cessation protocols has a significant effect on their tobacco-related practices (r = .35, variance shared = 12%). Self-efficacy and gender were both significantly correlated to tobacco related practices (r = .42, variance shared = 17%). A significant correlation was also found between self-efficacy and knowledge/skills (r = .60, variance shared = 36%). Attitudes/responsibility was not significantly correlated with any of the other measures. CONCLUSION: More resources should be dedicated to training Hispanic physicians in tobacco intervention. Training may facilitate practice by increasing knowledge, developing skills and, ultimately, enhancing feelings of self-efficacy.

Healthcare Use and Mammography Among Latinas With and Without Health Insurance Near the US-Mexico Border.

INTRODUCTION: Among Latinas, lacking health insurance and having lower levels of acculturation are associated with disparities in mammography screening. OBJECTIVE: We seek to investigate whether differences in lifetime mammography exist between Latina border residents by health insurance status and health care site (i.e., U.S. only or a combination of U.S. and Mexican health care). METHODS: Using data from the 2009 to 2010 Ecological Household Study on Latino Border Residents, mammography screening was examined among (n = 304) Latinas >40 years old. RESULTS: While more acculturated women were significantly (p < .05) more likely to report ever having a mammogram than less acculturated women, ever having a mammogram was not predicted by health care site or insurance status. CONCLUSION: Latinas who utilize multiple systems of care have lower levels of acculturation and health insurance, thus representing an especially vulnerable population for experiencing disparities in mammography screening.

Improved Cardiovascular Risk among Hispanic Border Participants of the Mi Corazón Mi Comunidad Promotores De Salud Model: The HEART II Cohort Intervention Study 2009-2013.

BACKGROUND: Community resources (parks, recreational facilities) provide opportunities for health promotion, but little is known about how to promote utilization of these resources and their impact on cardiovascular disease risk (CVD). METHODS: This cohort study evaluated the impact of an intervention called Mi Corazon Mi Comunidad (MiCMiC), which consisted of promoting use of community physical activity and nutrition resources by Promotoras de Salud/Community Health Workers. Participants were assessed at baseline and following the 4-month intervention. Attendance records were objectively collected to assess utilization of intervention programing. RESULTS: A total of five consecutive cohorts were recruited between 2009 and 2013. Participants were mostly females (86.0%), on average 46.6 years old, and 81% were low in acculturation. Participants who completed follow-up (n = 413) showed significant improvements in reported health behaviors and body composition. Higher attendance significantly predicted greater improvements. The baseline to 4-month change for the highest vs. the lowest attendance quartiles were for weight (-5.2 vs. +0.01 lbs, p < 0.001), waist circumference (-1.20 vs. -0.56 inches, p = 0.047), hip circumference (-1.13 vs. -0.41 inches, p < 0.001); hours of exercise/week (+3.87 vs. +0.81 hours, p < 0.001), proportion of participants eating five servings of fruits and vegetables/day (+54.7 vs. 14.7%, p < 0.001). CONCLUSION: Following the Promotora-led MiCMiC intervention, substantial improvements in health behaviors and modest improvements in cardiovascular risk factors were found. Greater utilization of community resources was associated with more favorable changes. This study provided preliminary evidence for the effectiveness of Promotora-led interventions for promoting use of existing community resources in CVD risk reduction.

Critical reflections on the role of CBPR within an RCT community health worker prevention intervention.

Coalescence of culturally relevant and community-based research with traditional scientific inquiry is necessary for the translation of science into practice. One methodology that has been identified as an important missing link in achieving the goal of combining science and community practice is the community-based participatory research approach, or CBPR. To demonstrate how CBPR has been successfully blended with randomized control trial (RCT) methodology, we showcase a randomized community trial that has shown efficacy in reducing cardiovascular risk factors integrating community health workers. The purpose of this article is 2-fold. First, it describes the process of merging the CBPR approach within an RCT framework and, second, it describes lessons learned in conducting CBPR-RCT research initiatives.

Perceptions of Community Health Workers (CHWs/PS) in the U.S.-Mexico border HEART CVD study.

Although prior research has shown that Community Health Workers/Promotores de Salud (CHW/PS) can facilitate access to care, little is known about how CHW/PS are perceived in their community. The current study reports the findings of a randomized telephone survey conducted in a high-risk urban community environment along the U.S.-Mexico border. In preparation for a community-based CHW/PS intervention called the HEART ecological study, the survey aimed to assess perceptions of CHW/PS, availability and utilization of community resources (recreational and nutrition related) and health behaviors and intentions. A total of 7,155 calls were placed to complete 444 surveys in three zip codes in El Paso, Texas. Results showed that participants felt that healthful community resources were available, but utilization was low and variable: 35% reported going to a park, 20% reported having taken a health class, few reported using a gym (12%), recreation center (8%), or YMCA/YWCA (0.9%). Awareness and utilization of CHW/PS services were low: 20% of respondents had heard of CHW/PS, with 8% reporting previous exposure to CHW/PS services. Upon review of a definition of CHW/PS, respondents expressed positive views of CHW/PS and their value in the healthcare system. Respondents who had previous contact with a CHW/PS reported a significantly more positive perception of the usefulness of CHW/PS (p = 0.006), were more likely to see CHW/PS as an important link between providers and patients (p = 0.008), and were more likely to ask a CHW/PS for help (p = 0.009). Participants who utilized CHW/PS services also had significantly healthier intentions to reduce fast food intake. Future research is needed to evaluate if CHW/PS can facilitate utilization of available community resources such as recreational facilities among Hispanic border residents at risk for CVD.

A path analysis of a randomized promotora de salud cardiovascular disease-prevention trial among at-risk Hispanic adults.

This study assessed effectiveness of an educational community intervention taught by promotoras de salud in reducing cardiovascular disease (CVD) risk among Hispanics using a structural equation modeling (SEM) approach. Model development was guided by a social ecological framework proposing CVD risk reduction through improvement of protective health behaviors, health beliefs, contextual and social factors. Participants were 328 Hispanic adults with at least one CVD risk factor. SEM analyses assessed direct and indirect effects of intervention participation on CVD risk (Framingham score) and latent variables nutrition intake and health beliefs. The model fit was adequate (root mean square error of approximation = .056 [90% confidence interval = .040, .072], comparative fit index = .967, normed fit index = .938, nonnormed fit index = .947). Intervention participation was associated with improved nutritional consumption, but not lower CVD risk. Stronger health beliefs predicted healthier nutritional habits. This project provided evidence for the adequacy of a conceptual framework that can be used to elicit new pathways toward CVD risk reduction among at-risk Hispanic populations.

Actions to control high blood pressure among hypertensive adults in Texas counties along the Mexico border: Texas BRFSS, 2007.

OBJECTIVES: We examined the prevalence of actions taken to control blood pressure as measured by taking antihypertensive medication or making lifestyle modifications among hypertensive adults residing along the Texas/Mexico border. METHODS: We used self-reported data from the 2007 Texas Behavioral Risk Factor Surveillance System, with oversampling of border counties. We calculated the age-standardized prevalence of actions taken to control hypertension by selected characteristics. RESULTS: In analyses that combined ethnicity with predominant language spoken, those least likely to take any action to control their blood pressure--either by taking an antihypertensive medication or by making any of four lifestyle modifications--were Spanish-speaking Hispanic people (83.2% ± 2.7% standard error [SE]), with English-speaking non-Hispanic people (88.9% ± 0.8% SE) having the highest prevalence of taking action to control blood pressure. When analyzed by type of medical category, uninsured Hispanic people (63.8% ± 4.8% SE) had the lowest prevalence of taking action to control their blood pressure compared with uninsured non-Hispanic people (75.4% ± 4.7% SE). Nonborder Texas residents with hypertension were more likely to take antihypertensive medications (78.4% ± 1.0% SE) than border county residents with hypertension (70.7% ± 2.0% SE). CONCLUSIONS: Public health efforts must be undertaken to improve the control of hypertension among residents of Texas counties along the Mexico border, particularly for uninsured Hispanic people.

Place of residence modifies the association between acculturation and dietary tools knowledge among Latina WIC participants: a multi-state study.

This cross-sectional study assessed: (a) awareness and knowledge of federal dietary tools (MyPyramid, Food Guide Pyramid (FGP), and food labels (FL)), and (b) the influence of acculturation and state of residence on FGP knowledge (FGPK) indicators among low-income Latina WIC participants (N = 479) living in Connecticut, Ohio, Texas, and California. Participants were familiar with FGP but only 37% recognized MyPyramid. FGPK was highest for fruits (71%) and lowest for the 'breads and cereals' group (12%). Less than half (47%) used FL's when grocery shopping. Living in OH, was associated with the lowest FGPK. Multivariate analyses showed that more acculturated individuals living in CT/CA had better FGPK than participants living in TX and their less acculturated counterparts in CT/CA. The forthcoming revised federal dietary tools need to be adequately disseminated among Latinos, with special emphasis on those with lower acculturation levels, living in rapid emerging Latino communities or in the US-Mexico border.

A randomized community intervention to improve hypertension control among Mexican Americans: using the promotoras de salud community outreach model.

The objectives of this study were: 1) to evaluate the acceptance, effectiveness, and sustainability of a promotora (community health worker) pilot program to improve hypertension control among medically underserved Mexican Americans of the El Paso, Texas area, and 2) to demonstrate improvements in clinical measures of blood pressure, BMI and waist circumference, self-reported behaviors and changes in attitudes and beliefs about blood pressure among Mexican American hypertensives. Participants were eligible if they had been diagnosed with hypertension and if they were willing to be randomized as either participants in the intervention or as controls. A total of 58 participants enrolled in the intervention group and 40 participants served as controls. This was a 9-week promotora intervention. Health behavior constructs and clinical data were measured pre-post intervention. Perceived benefits, and two heart-healthy behaviors (salt and sodium, and cholesterol and fat) were shown to be statistically significantly different between the intervention and control groups.

Binational utilization and barriers to care among Mexican American border residents with diabetes / Utilización binacional y barreras a la atención en las personas con diabetes que residen en la frontera mexicano-estadounidense

OBJECTIVE: To assess whether U.S.-Mexico border residents with diabetes 1) experience greater barriers to medical care in the United States of America versus Mexico and 2) are more likely to seek care and medication in Mexico compared to border residents without diabetes.

OBJETIVO: Evaluar si las personas con diabetes que residen en la frontera mexicano-estadounidense 1) encuentran mayores barreras para obtener atención médica en los Estados Unidos de América que en México; y 2) acuden a México en busca de atención y medicación con mayor probabilidad que las personas no diabéticas que residen en la frontera. MÉTODOS: Durante el 2009 y el 2010, en una muestra de 1 002 hogares mexicano-estadounidenses, se llevó a cabo una encuesta transversal de salud en dos etapas, estratificada y aleatorizada. RESULTADOS: Las tasas de diabetes eran elevadas (15,4%). La mayor parte de las personas con diabetes (86%) notificaron comorbilidades. En comparación con los participantes no diabéticos, los afectados de diabetes experimentaban dificultades algo mayores para pagar US$ 25 (P = 0,002) o US$ 100 (P = 0,016) por recibir atención médica, y encontraban mayores barreras en materia de transporte e idioma (P = 0,011 y 0,014, respectivamente) para ser atendidos en los Estados Unidos, aunque era más probable que contaran con una persona o lugar adonde acudir en busca de atención médica y para ser sometidos a tamizaje. Una cuarta parte de los participantes acudían a México en busca de atención o medicamentos. Una edad menor y el haber vivido en México se asociaban con la búsqueda de atención en México, pero no el padecer diabetes. La presencia de múltiples barreras financieras se asociaba independientemente con una probabilidad aproximadamente tres veces mayor de acudir a México en busca de atención médica o medicación. Las barreras idiomáticas se asociaban con la búsqueda de atención en México. La confusión acerca de los trámites para recibir atención médica y la percepción de no recibir siempre un trato respetuoso por parte de los proveedores de atención médica en los Estados Unidos se asociaban con la búsqueda de atención y medicación en México (odds ratio, 1,70 - 2,76). CONCLUSIONES: La notificación de barreras modificables a la atención médica fue frecuente entre los participantes y algo más frecuente entre 1) las personas con diabetes; y 2) los que buscaban se atendidos en México. Sin embargo, estos fenómenos son estadísticamente independientes; no era más probable que las personas con diabetes utilizaran servicios en México. Ambos conjuntos de problemas (las barreras que deben afrontar las personas con diabetes, las barreras relacionadas con el uso de servicios en México) pueden coexistir, y proporcionan oportunidades para mejorar el acceso a la atención y el tratamiento de las enfermedades.
