Evaluation of Healthy Fit: A Community Health Worker Model to Address Hispanic Health Disparities.

INTRODUCTION: Hispanics in the United States have disproportionately high rates of obesity, hypertension, and diabetes and poorer access to preventive health services. Healthy Fit uses community health workers to extend public health department infrastructure and address Hispanic health disparities related to cardiovascular disease and access to preventive health services. We evaluated the effectiveness of Healthy Fit in 1) reaching Hispanic Americans facing health disparities, and 2) helping participants access preventive health services and make behavior changes to improve heart health. METHODS: Community health workers recruited a sample of predominantly low-income Hispanic immigrant participants (N = 514). Following a health screening, participants received vouchers for breast, cervical, and colorectal cancer screening, and received vaccinations as needed for influenza, pneumonia, and human papillomavirus. Participants who were overweight or had high blood pressure received heart health fotonovelas and referrals to community-based exercise activities. Community health workers completed follow-up phone calls at 1, 3, and 6 months after the health screening to track participant uptake on the referrals and encourage follow-through. RESULTS: Participants faced health disparities related to obesity and screening for breast, cervical, and colorectal cancer. Postintervention completion rates for breast, cervical, and colorectal cancer screening were 54%, 43%, and 32%, respectively, among participants who received a voucher and follow-up phone call. Among participants with follow-up data who were overweight or had high blood pressure, 70% read the fotonovela, 66% completed 1 or more heart health activities in the fotonovela, 21% attended 1 or more community-based exercise activities, and 79% took up some other exercise on their own. CONCLUSION: Healthy Fit is a feasible and low-cost strategy for addressing Hispanic health disparities related to cancer and cardiovascular disease.

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.

Improving heart healthy lifestyles among participants in a Salud para su Corazón promotores model: the Mexican pilot study, 2009-2012.

INTRODUCTION: In Mexico, cardiovascular disease and its risk factors are growing problems and major public health concerns. The objective of this study was to implement cardiovascular health promotion and disease prevention activities of the Salud para su Corazón model in a high-risk, impoverished, urban community in Mexico City. METHODS: We used a pretest-posttest (baseline to 12-week follow-up) design without a control group. Material from Salud para su Corazón was validated and delivered by promotores (community health workers) to community members from 6 geographic areas. Two validated, self-administered questionnaires that assessed participants' knowledge and behaviors relating to heart health were administered. We used t tests and χ(2) tests to evaluate pretest and posttest differences, by age group (≤60 and >60 years), for participants' 3 heart-healthy habits, 3 types of physical activity, performance skills, and anthropometric and clinical measurements. RESULTS: A total of 452 (82%) adult participants completed the program. Heart-healthy habits from pretest to posttest varied by age group. "Taking action" to modify lifestyle behaviors increased among adults aged 60 or younger from 31.5% to 63.0% (P < .001) and among adults older than 60 from 30.0% to 45.0% (P < .001). Positive responses for cholesterol and fat consumption reduction were seen among participants 60 or younger (P = .03). Among those older than 60, salt reduction and weight control increased (P = .008). Mean blood glucose concentration among adults older than 60 decreased postintervention (P = .03). CONCLUSION: Significant improvements in some heart-healthy habits were seen among adult participants. The model has potential to improve heart-healthy habits and facilitate behavioral change among high-risk adults.

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.

Integrating health literacy and ESL: an interdisciplinary curriculum for Hispanic immigrants.

Adult Hispanic immigrants are at a greater risk of experiencing the negative outcomes related to low health literacy, as they confront cultural and language barriers to the complex and predominately monolingual English-based U.S. health system. One approach that has the potential for simultaneously addressing the health, literacy, and language needs of Hispanics is the combination of health literacy and English as a second language (ESL) instruction. The purpose of the project was to evaluate the feasibility of using ESL instruction as a medium for improving health literacy among Hispanic immigrants. Objectives included the development, implementation, and evaluation of an interdisciplinary health literacy/ESL curriculum that integrates theories of health literacy and health behavior research and practice, sociocultural theories of literacy and communication, and adult learning principles. This article describes the curriculum development process and provides preliminary qualitative data on learners' experiences with the curriculum. Results indicate that the curriculum was attractive to participants and that they were highly satisfied with both the format and content. The curriculum described here represents one example of an audience-centered approach designed to meet the specific health and literacy needs of the Hispanic population on the U.S.-Mexico border. The combination of ESL and health literacy contributed to a perceived positive learning experience among participants. Interdisciplinary approaches to health literacy are recommended.

Reporting guidelines and the American Journal of Public Health's adoption of Preferred Reporting Items for Systematic reviews and Meta-Analyses.

Widespread recognition of the need to improve the science of published research, as well as the moral and ethical reasons for adequately reporting study results, has spurred recent interest in strengthening journal research reporting through the use of reporting guidelines. Reporting guidelines also provide information for readers to judge study quality. American Journal of Public Health previously adopted the Consolidated Standards of Reporting Trials and Transparent Reporting of Evaluations With Nonrandomized Designs guidelines and recently endorsed the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. In adopting these guidelines, the journal aims to support authors, reviewers, and editors in reporting and evaluating systematic reviews of public health policy and practice priorities.

An ecological model using promotores de salud to prevent cardiovascular disease on the US-Mexico border: the HEART project.

BACKGROUND: To address cardiovascular disease risk factors among Hispanics, a community model of prevention requires a comprehensive approach to community engagement. The objectives of our intervention were to reduce cardiovascular disease risk factors in Hispanics living in 2 low-income areas of El Paso, Texas, and to engage the community in a physical activity and nutrition intervention. METHODS: Drawing on lessons learned in phase 1 (years 2005-2008) of the HEART Project, we used an iterative, community-based process to develop an intervention based on an ecological framework. New community partners were introduced and community health workers delivered several elements of the intervention, including the curriculum entitled "Mi Corazón, Mi Comunidad" ("MiCMiC" [My Heart, My Community]). We received feedback from the project's Community Health Academy and Leadership Council throughout the development process and established a policy agenda that promotes integration of community health workers into the local and state workforce. OUTCOME: Collaboration with 2 new community partners, the YWCA and the Department of Parks and Recreation, were instrumental in the process of community-based participatory research. We enrolled 113 participants in the first cohort; 78% were female, and the mean age was 41 years. More than 50% reported having no health insurance coverage. Seventy-two (60%) participants attended 1 or more promotora-led Su Corazón, Su Vida sessions, and 74 (62%) participants attended 1 or more of the 15 exercise classes. INTERPRETATION: HEART phase 2 includes a multilevel ecological model to address cardiovascular disease risk among Hispanics. Future similarly targeted initiatives can benefit from an ecological approach that also embraces the promotora model.

Community health workers can be a public health force for change in the United States: three actions for a new paradigm.

Community health workers (CHWs) have gained increased visibility in the United States. We discuss how to strengthen the roles of CHWs to enable them to become collaborative leaders in dramatically changing health care from "sickness care" systems to systems that provide comprehensive care for individuals and families and supports community and tribal wellness. We recommend drawing on the full spectrum of CHWs' roles so that they can make optimal contributions to health systems and the building of community capacity for health and wellness. We also urge that CHWs be integrated into "community health teams" as part of "medical homes" and that evaluation frameworks be improved to better measure community wellness and systems change.

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.

What About Promotores? Promotores' Psychosocial Determinants That Influenced the Delivery of a Cervical Cancer Education Intervention to Hispanics.

This study tested whether a cancer education intervention affected promotores' self-efficacy to deliver an intervention to Hispanics and which psychosocial determinants of promotores influenced the number of Hispanic residents reached by promotores in the subsequent education intervention. A quasi-experimental, pre/post-design with a treatment group (no control) assessed differences for promotores (n = 136) before and after exposure to the cancer education intervention. The design also included a cross-sectional evaluation of the number of residents promotores reached with the educational intervention. After being trained, the promotores delivered the intervention to Hispanic residents (n = 1,469). Paired t-tests demonstrated increases in promotores' self-efficacy from pre- to post-intervention. Regression models assessed associations between the numbers of residents reached and select psychosocial determinants of promotores. Age and promotores' years of experience influenced their delivery of a cervical cancer education intervention to Hispanics, but not their delivery of breast or colorectal cancer education interventions. This is the first study to examine which psychosocial determinants influence promotores delivery of cancer education interventions. The outcomes potentially have implications for CHW interventions and training by examining this potential connection between CHWs' psychosocial determinants and intervention outcomes.

The Development of a Novel, Standards-Based Core Curriculum for Community Facing, Clinic-Based Community Health Workers.

Introduction: Historically, CHW trainings have been developed to support community-based CHWs. When CHWs have been trained to engage with patients, typically such trainings have been for short term grant funded projects, focusing on a specific health intervention and not for long term, ongoing engagement of CHWs employed in clinical settings. To the best of our knowledge, this is the first such effort to describe the development of a standards-based training curriculum for clinic-based CHWs using a novel conceptual framework. Methods: Our conceptual approach for curricular development has several innovative features including: (1) a foundational consultation process with CHW national experts to inform curricular development approach, process and content; (2) utilization of the CHW Consensus Project (C3 Project) to provide curricular standards and guide learning objectives; (3) integration of three key stakeholder group perspectives (patients, healthcare teams, and healthcare systems); (4) use of popular education principles, aiming to foster a collaborative learning process; (5) integration of adult learning principles which build on learners' experiences, culminating in a modified apprenticeship model and (6) collaboration with clinical partners throughout planning and development of the curriculum. Results: The resulting standards-based curriculum is comprised of 10 modules, which span three areas of focus: (1) Establishing a professional CHW identity and competencies; (2) Outlining the context, processes and key actors in health care settings with whom CHWs will engage; and (3) Identifying the main forces that shape health and health care outcomes of patients/families and communities. Discussion: We highlight four lessons from our curriculum development process that may help other such efforts. First, curricular development should utilize CHW standards, existing training materials, and community-focused principles to inform curricular content and learning outcomes. Second, curricula should support training delivery using experience-based, participatory approaches, consistent with adult education and popular education principles. Third, training development for clinical settings should also draw from clinical CHW experiences and input. Fourth, curricula should support training for key stakeholders and champions in clinical organizations to improve organizational readiness for integrating CHWs into healthcare teams and health systems. Our results contribute to growing research on effective CHW training methods for clinical settings.

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.

Talk to PAPA: A Systematic Review of Patient/Participant (PAPA) Feedback on Interactions With Community Health Workers Using a Depth Analysis Approach.

Because of their shared backgrounds, community health workers' (CHWs) care of patients/program participants (PAPAs) is assumed to be acceptable, and often not evaluated empirically. Using PRISMA guidelines, we reviewed 9560 articles from 5 databases, selected 37 articles for full-text review, and developed a 5-dimensional depth analysis (focus, context, meaning, range, and voices) to characterize quality/quantity of PAPA feedback. Depth analyses clarified a spectrum of PAPA responses from extremely positive to ambivalence to outright distrust and frustration with perceived CHW limitations. Designing evaluations with 5-dimensional depth analysis can enhance PAPA feedback quality and improve evidence-based, patient-centered, CHW care delivery.

A promotora de salud model for addressing cardiovascular disease risk factors in the US-Mexico border region.

INTRODUCTION: In 2002, the National Heart, Lung, and Blood Institute partnered with the Health Resources and Services Administration's (HRSA's) Bureau of Primary Health Care and Office of Rural Health Policy to address cardiovascular health in the US-Mexico border region. From 2003 through 2005, the 2 agencies agreed to conduct an intervention program using Salud para su Corazón with promotores de salud (community health workers) in high-risk Hispanic communities served by community health centers (CHCs) in the border region to reduce risk factors and improve health behaviors. METHODS: Promotores de salud from each CHC delivered lessons from the curriculum Your Heart, Your Life. Four centers implemented a 1-group pretest-posttest study design. Educational sessions were delivered for 2 to 3 months. To test Salud para su Corazón-HRSA health objectives, the CHCs conducted the program and assessed behavioral and clinical outcomes at baseline, 3 months, 6 months, and 12 months after the intervention. A 2-sample paired t test and analyses of variance were used to evaluate differences from baseline to postintervention. RESULTS: Changes in heart-healthy behaviors were observed, as they have been in previous Salud para su Corazón studies, lending credibility to the effectiveness of a promotores de salud program in a clinical setting. Positive changes were also observed in low-density lipoprotein cholesterol level, triglyceride level, waist circumference, diastolic blood pressure, weight, and glycated hemoglobin (HbA1c). CONCLUSION: Results suggest that integrating promotores de salud into clinical practices is a promising strategy for culturally competent and effective service delivery. Promotores de salud build coalitions and partnerships in the community. The Salud para su Corazón-HRSA initiative was successful in helping to develop an infrastructure to support a promotores de salud workforce in the US-Mexico border region.

Use of community-based participatory research to disseminate baseline results from a cardiovascular disease randomized community trial for Mexican Americans living in a U.S.-Mexico border community.

INTRODUCTION: This article describes the development of a community-based participatory research (CBPR) process conducted in the context of a randomized community health education trial utilizing community health workers (CHWs). OBJECTIVES: To present lessons learned from the utilization of CBPR methodology in a cardiovascular disease (CVD) prevention trial among Mexican American adults in a U.S.-Mexico border community and to disseminate the baseline results associated with risk factors for CVD and their associated demographic and psychosocial characteristics. METHODS: Participants were 328 Hispanic adults ages 30-75 with at least one risk factor for CVD (overweight, smoking, high cholesterol, diabetic or hypertensive), who were recruited through approaching households in randomly selected census tracts within a specified zip code area. RESULTS: CBPR methods were applied during the different stages of the research enterprise to support the development and implementation of the intervention trial aim at reducing cardiovascular risk factors for Mexican American adults. Data from baseline were used as an important component of dialogue with the community. DISCUSSION: CBPR proved to be a good learning process for all partners involved. The risk profile of the participants demonstrated the "epidemic" nature of CVD morbidity conditions associated with Mexican origin populations living in a U.S.-Mexico border community. The CBPR dialogue was instrumental as a process to help disseminate to the community the need for projects like the one described in this article.

Evaluation of respiratory symptoms and their possible association with residential indoor bioaerosol concentrations and other environmental influences.

The study discussed here evaluated the presence of self-reported respiratory symptoms and their association with indoor bioaerosol concentrations over a year-long study in the El Paso, Texas, region. The authors collected air samples from homes to assess seasonal differences in bacterial and fungal bioaerosol concentrations. They distributed a health questionnaire to the participating homeowner during each seasonal air sampling. The authors used this questionnaire to assess whether the homeowners were suffering from specific symptoms prior to each sampling. Descriptive statistics and logistic regressions were conducted to model the relationship among "high" reporters of symptoms, bioaerosols, and environmental factors. The authors collected evidence to support an association between indoor respirable bacterial concentrations and homeowners that reported at least eight respiratory symptoms (odds ratio [OR] = 1.10, p = .045). Smoking status, indoor humidity, and season also displayed associations with homeowners that reported at least eight respiratory symptoms (current smokers OR = 3.3, p = .042; indoor humidity OR = 1.5, p = .030; spring season OR = 7.2, p = .001; fall season OR = 3.4, p = .008).
