RESUMEN

PURPOSE: Despite proven benefits, few cancer patients exercise during chemotherapy. The American College of Sports Medicine's Exercise is Medicine® (EIM) initiative describes a model to integrate exercise into oncology care, based upon assessing patients' ability to exercise safely, advising on exercise benefits, and referring patients to exercise. We developed and tested a strategy to implement EIM in a community-based oncology clinic, to assess-advise-refer 20 patients undergoing chemotherapy to a 3-month online exercise class, and measured implementation outcomes. METHODS: Using a community-based provider participation in research (CBPPR) model, researchers and staff co-designed and tested a 4-level implementation strategy, with a goal of assessing-advising-referring 20 cancer patients to exercise. Surveys and interviews were conducted with 12 (100%) staff at baseline and post-implementation on acceptability/appropriateness/feasibility, perceptions of individual implementation roles, and organizational strengths/conditions. Data were analyzed using correlations, t-tests, and content analysis. RESULTS: The proposed strategy was revised in collaboration with staff who requested assistance for recruitment and data collection. EIM was successfully implemented with 41 (92%) patients assessed, 37 (90%) advised, and 22 (60%) referred to exercise classes. Barriers to implementation were staff shortages and time constraints; facilitators included research team supports. Staff's perceived organizational strengths were positively correlated with exercise promotion acceptability, appropriateness, and feasibility. There were no statistically significant changes in implementation outcomes (acceptability/appropriateness/feasibility) post-implementation. CONCLUSIONS: Using a collaborative model, EIM was successfully implemented in a community oncology clinic; however, the clinic required significant support from the research team. Adaptations to the EIM process may be required to improve implementation outcomes.

RESUMEN

BACKGROUND: Rural Latino children have higher rates of obesity compared to non-Latino Whites. Schools are in a unique position to address rural childhood obesity through policies. While evidence exists on factors that promote or impede school-based physical activity (PA) and nutrition policies, only a fraction has been in rural communities. This study seeks to understand 1) the knowledge and perceptions of school nutrition and PA policies and 2) barriers and facilitators to their implementation among rural school stakeholders from Washington State. METHODS: We conducted 20 semi-structured, in-depth interviews with school stakeholders (e.g., principals and school nutrition directors) from four K-12 school districts in the Lower Yakima Valley of Eastern Washington State. Thematic analysis was conducted using inductive, constant comparison approach to identify themes around knowledge and perceptions of policies and barriers and facilitators of policy implementation. RESULTS: Three main themes were identified: perceptions and knowledge of school PA and nutrition policies, barriers to policy implementation, and facilitators of policy implementation. The majority of stakeholders were supportive of school-based policies promoting PA and a healthy diet, even when lacking a specific understanding of these policies. Four subthemes were identified as barriers to policy implementation: viewing PA as a low priority, misuse of recess time, funding constraints, and lack of strong leadership. Facilitators of implementation included strong leadership at the district level, creating healthy norms through school-community linkages and pooling community resources to improve nutrition and PA among children. CONCLUSIONS: Schools provide a unique setting to promote healthy diet and PA behaviors among children and their families. Study findings show that while knowledge of specific nutrition and PA policies may vary, support for such policies were high among rural stakeholders. Study findings can inform policy development and support strategies for policy implementation in rural settings. Future studies may want to examine whether implementation of strategies addressing the barriers and enhancing facilitators lead to success in rural school settings.

RESUMEN

BACKGROUND: In some countries, breast cancer age-standardised mortality rates have decreased by 2-4% per year since the 1990s, but others have yet to achieve this outcome. In this study, we aimed to characterise the associations between national health system characteristics and breast cancer age-standardised mortality rate, and the degree of breast cancer downstaging correlating with national age-standardised mortality rate reductions. METHODS: In this population-based study, national age-standardised mortality rate estimates for women aged 69 years or younger obtained from GLOBOCAN 2020 were correlated with a broad panel of standardised national health system data as reported in the WHO Cancer Country Profiles 2020. These health system characteristics include health expenditure, the Universal Health Coverage Service Coverage Index (UHC Index), dedicated funding for early detection programmes, breast cancer early detection guidelines, referral systems, cancer plans, number of dedicated public and private cancer centres per 10 000 patients with cancer, and pathology services. We tested for differences between continuous variables using the non-parametric Kruskal-Wallis test, and for categorical variables using the Pearson χ2 test. Simple and multiple linear regression analyses were fitted to identify associations between health system characteristics and age-standardised breast cancer mortality rates. Data on TNM stage at diagnosis were obtained from national or subnational cancer registries, supplemented by a literature review of PubMed from 2010 to 2020. Mortality trends from 1950 to 2016 were assessed using the WHO Cancer Mortality Database. The threshold for significance was set at a p value of 0·05 or less. FINDINGS: 148 countries had complete health system data. The following variables were significantly higher in high-income countries than in low-income countries in unadjusted analyses: health expenditure (p=0·0002), UHC Index (p<0·0001), dedicated funding for early detection programmes (p=0·0020), breast cancer early detection guidelines (p<0·0001), breast cancer referral systems (p=0·0030), national cancer plans (p=0·014), cervical cancer early detection programmes (p=0·0010), number of dedicated public (p<0·0001) and private (p=0·027) cancer centres per 10 000 patients with cancer, and pathology services (p<0·0001). In adjusted multivariable regression analyses in 141 countries, two health system characteristics were significantly associated with lower age-standardised mortality rates: higher UHC Index levels (ß=-0·12, 95% CI -0·16 to -0·08) and increasing numbers of public cancer centres (ß=-0·23, -0·36 to -0·10). These findings indicate that each unit increase in the UHC Index was associated with a 0·12-unit decline in age-standardised mortality rates, and each additional public cancer centre per 10 000 patients with cancer was associated with a 0·23-unit decline in age-standardised mortality rate. Among 35 countries with available breast cancer TNM staging data, all 20 that achieved sustained mean reductions in age-standardised mortality rate of 2% or more per year for at least 3 consecutive years since 1990 had at least 60% of patients with invasive breast cancer presenting as stage I or II disease. Some countries achieved this reduction without most women having access to population-based mammographic screening. INTERPRETATION: Countries with low breast cancer mortality rates are characterised by increased levels of coverage of essential health services and higher numbers of public cancer centres. Among countries achieving sustained mortality reductions, the majority of breast cancers are diagnosed at an early stage, reinforcing the value of clinical early diagnosis programmes for improving breast cancer outcomes. FUNDING: None.

RESUMEN

BACKGROUND: Rural Latino children and adults are less active than urban and non-Latino counterparts. We examined physical activity (PA) patterns of rural Latino children and their parents, and explored parental beliefs about and reported barriers of Latino family physical activity. Latino families in a rural area in eastern Washington state, with children in grades 3-5 were included. METHODS: We used mixed methods. Children (n = 27) and parents (n = 25) wore an accelerometer for 5 days; parents (n = 31) participated in a semi-structured interview and completed a demographic survey. Parent and child activity levels were compared using paired t-tests; interviews were analyzed with qualitative content analysis. RESULTS: Although 100% children and 46% parents met physical activity guidelines, parents and children spent most of the day in sedentary behaviors. Parent-reported PA barriers included their long work hours, lack of transportation, and their child's screen-time. CONCLUSION: Addressing barriers and reducing sedentary time could increase PA of rural Latino families.

RESUMEN

BACKGROUND: Implementation of evidence-based, resource-appropriate guidelines for breast cancer control should be preceded by a baseline assessment or situational analysis to assess breast health infrastructure, workforce capacity, patient pathways, existing practices, accessibility, and costs. METHODS: To support the assessment of breast health care systems within the broader context in which they exist, the Breast Health Global Initiative (BHGI) developed, tested, and refined a set of situational analysis tools with which to guide the assessment of breast health care capacity, identify the relative strengths and weaknesses of the health system, and support stakeholders in prioritizing actionable items to advance breast cancer care using evidence-based strategies tailored to their setting. The tools address 6 domains of breast health care delivery: 1) breast cancer early detection practices; 2) breast cancer awareness programs; 3) the availability of breast cancer surgery; 4) the availability of pathology; 5) the availability of radiotherapy, and 6) the availability of systemic therapy services. The current study also describes the more comprehensive International Atomic Energy Agency Programme of Action for Cancer Therapy (PACT) integrated missions for PACT (imPACT) review. RESULTS: As of 2020, 5 formal BHGI situational analyses have been performed in India, Brazil, Panama, Tanzania, and Uganda. As of August 2019, a total of 100 imPACT reviews have been conducted in 91 countries. These assessments can contribute to more informed policymaking. CONCLUSIONS: Situational analyses are a prerequisite for the development of resource-appropriate strategies with which to advance breast cancer control in any setting and should assess services across the entire breast health care continuum as well as the broader structural, sociocultural, personal, and financial contexts within which they operate.

RESUMEN

BACKGROUND: Successful breast cancer detection programs rely on standardized reporting and interpreting systems, such as the Breast Imaging Reporting and Data System (BI-RADS), to improve system performance. In low-income and middle-income countries, evolving diagnostic programs have insufficient resources to either fully implement BI-RADS or to periodically evaluate the program's performance, which is a necessary component of BI-RADS. This leads to inconsistent breast ultrasound interpretation and a failure to improve performance. METHODS: The authors applied the Breast Health Global Initiative's phased implementation strategy to implement diagnostic ultrasound and BI-RADS within the context of a limited-resource setting. RESULTS: The authors recommended starting with triage ultrasound to distinguish suspicious masses from normal breast tissue and benign masses such as cysts because the majority of health workers performing ultrasounds at this level have minimal breast imaging experience. Transitioning to full diagnostic ultrasound with condensed or full BI-RADS should occur after performance and quality metrics have been met. CONCLUSIONS: Transitioning through these phases across facilities likely will occur at different times, particularly in rural versus urban settings.

RESUMEN

BACKGROUND: Greater than 80% of women presenting for breast cancer treatment in Uganda have late-stage disease, which is attributable to a dysfunctional referral system and a lack of recognition of the early signs and symptoms among primary health care providers, and compounded by the poor infrastructure and inadequate human capacity. Improving the breast health care system requires a systemic approach beginning with situational analysis to identify systematic gaps that prevent sustainable improvements in outcome. METHODS: The authors performed a situational analysis of the breast health care system using methods developed by the Breast Health Global Initiative. Based on their findings, they developed a series of recommendations for strengthening the health system for the early diagnosis of breast cancer based on clinical detection, referral, tissue sampling, and diagnosis. RESULTS: Deficits in the recognition of breast cancer signs and symptoms, the underuse of clinical breast examination as a diagnostic and/or screening tool, the centralization of diagnostic tests (radiology and pathology), reliance on excisional biopsies rather than needle biopsies, and a lack of trained professionals and knowledge of the referral system all contribute to significant health system delays. CONCLUSIONS: To strengthen referral networks and improve the early diagnosis of breast cancer in Uganda, national referral hospitals should provide educational programs to primary health care providers in community health centers (CHCs), at which the majority of women first present with symptoms. At secondary district-level facilities in which imaging and tissue sampling can be performed, the capacity for diagnostic testing could be increased through task shifting of basic interpretation (abnormal vs normal) from specialists to nonspecialists using networking technology to facilitate remote oversight from specialists at the national referral hospitals.

RESUMEN

BACKGROUND: Breast cancer advocacy movements, driven by advocate-led civil society organizations (CSOs), have proven to be a powerful force for the advancement of cancer control in high-income countries (HICs). However, although patient advocacy movements are growing in low-income and middle-income countries (LMICs) in response to an increasing cancer burden, the experiences and needs of advocate-led breast cancer CSOs in LMICs is understudied. METHODS: The authors conducted a qualitative study using in-depth interviews and focus group discussions with 98 participants representing 23 LMICs in Eastern Europe, Central Asia, East and Southern Africa, and Latin America. RESULTS: Despite geographic, cultural, and socioeconomic differences, the common themes that emerged from the data across the 3 regions are strikingly similar: trust, knowledge gaps, stigma, sharing experiences, and sustainability. The authors identified common facilitators (training/education, relationship building/networking, third-party facilitators, and communication) and barriers (mistrust, stigma, organizational fragility, difficulty translating HIC strategies) to establishing trust, collaboration, and advancing cancer advocacy efforts. To the authors' knowledge, the current study is the first to describe the role that coalitions and regional networks play in advancing breast cancer advocacy in LMICs across multiple regions. CONCLUSIONS: The findings of the current study corroborate the importance of investing in 3-way partnerships between CSOs, political leaders, and health experts. When provided with information that is evidence-based and resource appropriate, as well as opportunities to network, advocates are better equipped to achieve their goals. The authors propose that support for CSOs focuses on building trust through increasing opportunities for engagement, disseminating best practices and evidence-based information, and fostering the creation of platforms for partnerships and networks.

RESUMEN

The adoption of the goal of universal health coverage and the growing burden of cancer in low- and middle-income countries makes it important to consider how to provide cancer care. Specific interventions can strengthen health systems while providing cancer care within a resource-stratified perspective (similar to the World Health Organization-tiered approach). Four specific topics are discussed: essential medicines/essential diagnostics lists; national cancer plans; provision of affordable essential public services (either at no cost to users or through national health insurance); and finally, how a nascent breast cancer program can build on existing programs. A case study of Zambia (a country with a core level of resources for cancer care, using the Breast Health Global Initiative typology) shows how a breast cancer program was built on a cervical cancer program, which in turn had evolved from the HIV/AIDS program. A case study of Brazil (which has enhanced resources for cancer care) describes how access to breast cancer care evolved as universal health coverage expanded. A case study of Uruguay shows how breast cancer outcomes improved as the country shifted from a largely private system to a single-payer national health insurance system in the transition to becoming a country with maximal resources for cancer care. The final case study describes an exciting initiative, the City Cancer Challenge, and how that may lead to improved cancer services.

RESUMEN

BACKGROUND: The Breast Health Global Initiative (BHGI) established a series of resource-stratified, evidence-based guidelines to address breast cancer control in the context of available resources. Here, the authors describe methodologies and health system prerequisites to support the translation and implementation of these guidelines into practice. METHODS: In October 2018, the BHGI convened the Sixth Global Summit on Improving Breast Healthcare Through Resource-Stratified Phased Implementation. The purpose of the summit was to define a stepwise methodology (phased implementation) for guiding the translation of resource-appropriate breast cancer control guidelines into real-world practice. Three expert consensus panels developed stepwise, resource-appropriate recommendations for implementing these guidelines in low-income and middle-income countries as well as underserved communities in high-income countries. Each panel focused on 1 of 3 specific aspects of breast cancer care: 1) early detection, 2) treatment, and 3) health system strengthening. RESULTS: Key findings from the summit and subsequent article preparation included the identification of phased-implementation prerequisites that were explored during consensus debates. These core issues and concepts are key components for implementing breast health care that consider real-world resource constraints. Communication and engagement across all levels of care is vital to any effectively operating health care system, including effective communication with ministries of health and of finance, to demonstrate needs, outcomes, and cost benefits. CONCLUSIONS: Underserved communities at all economic levels require effective strategies to deploy scarce resources to ensure access to timely, effective, and affordable health care. Systematically strategic approaches translating guidelines into practice are needed to build health system capacity to meet the current and anticipated global breast cancer burden.

RESUMEN

When breast cancer is detected and treated early, the chances of survival are very high. However, women in many settings face complex barriers to early detection, including social, economic, geographic, and other interrelated factors, which can limit their access to timely, affordable, and effective breast health care services. Previously, the Breast Health Global Initiative (BHGI) developed resource-stratified guidelines for the early detection and diagnosis of breast cancer. In this consensus article from the sixth BHGI Global Summit held in October 2018, the authors describe phases of early detection program development, beginning with management strategies required for the diagnosis of clinically detectable disease based on awareness education and technical training, history and physical examination, and accurate tissue diagnosis. The core issues address include finance and governance, which pertain to successful planning, implementation, and the iterative process of program improvement and are needed for a breast cancer early detection program to succeed in any resource setting. Examples are presented of implementation, process, and clinical outcome metrics that assist in program implementation monitoring. Country case examples are presented to highlight the challenges and opportunities of implementing successful breast cancer early detection programs, and the complex interplay of barriers and facilitators to achieving early detection for breast cancer in real-world settings are considered.

RESUMEN

Optimal treatment outcomes for breast cancer are dependent on a timely diagnosis followed by an organized, multidisciplinary approach to care. However, in many low- and middle-income countries, effective care management pathways can be difficult to follow because of financial constraints, a lack of resources, an insufficiently trained workforce, and/or poor infrastructure. On the basis of prior work by the Breast Health Global Initiative, this article proposes a phased implementation strategy for developing sustainable approaches to enhancing patient care in limited-resource settings by creating roadmaps that are individualized and adapted to the baseline environment. This strategy proposes that, after a situational analysis, implementation phases begin with bolstering palliative care capacity, especially in settings where a late-stage diagnosis is common. This is followed by strengthening the patient pathway, with consideration given to a dynamic balance between centralization of services into centers of excellence to achieve better quality and decentralization of services to increase patient access. The use of resource checklists ensures that comprehensive therapy or palliative care can be delivered safely and effectively. Episodic or continuous monitoring with established process and quality metrics facilitates ongoing assessment, which should drive continual process improvements. A series of case studies provides a snapshot of country experiences with enhancing patient care, including the implementation of national cancer control plans in Kenya, palliative care in Romania, the introduction of a 1-stop clinic for diagnosis in Brazil, the surgical management of breast cancer in India, and the establishment of a women's cancer center in Ghana.

RESUMEN

Cancer is now the second leading cause of death in the Caribbean. Despite this growing burden, many Caribbean small island nations have health systems that struggle to provide optimal cancer care for their populations. In this Series paper, we identify several promising strategies to improve cancer prevention and treatment that have emerged across small island nations that are part of the Caribbean Community. These strategies include the establishment of a Caribbean cancer registry hub, the development of resource-appropriate clinical guidelines, innovations in delivering specialty oncology services (eg, paediatric oncology and palliative care), improving access to opioids, and developing regional training capacity in palliative medicine. These developments emphasise the crucial role of public-private partnerships in improving health care for the region and show how fostering strategic collaborations with colleagues and centres in more developed countries, who can contribute specialised expertise and improve regional collaboration, can improve care across the cancer control continuum.

RESUMEN

BACKGROUND: Certain eating behaviors are common among women with obesity. Whether these behaviors influence outcomes in weight loss programs, and whether such programs affect eating behaviors, is unclear. METHODS: Our aim was to examine the effect of baseline eating behaviors on intervention adherence and weight among postmenopausal women with overweight or obesity, and to assess intervention effects on eating behaviors. Four hundred and 39 women (BMI ≥25 kg/m2) were randomized to 12 months of: i) dietary weight loss with a 10% weight loss goal ('diet'; n = 118); ii) moderate-to-vigorous intensity aerobic exercise for 225 mins/week ('exercise'; n = 117); iii) combined dietary weight loss and exercise ('diet + exercise'; n = 117); or iv) no-lifestyle change control (n = 87). At baseline and 12 months, restrained eating, uncontrolled eating, emotional eating and binge eating were measured by questionnaire; weight and body composition were assessed. The mean change in eating behavior scores and weight between baseline and 12 months in the diet, exercise, and diet + exercise arms were each compared to controls using the generalized estimating equation (GEE) modification of linear regression adjusted for age, baseline BMI, and race/ethnicity. RESULTS: Baseline restrained eating was positively associated with change in total calories and calories from fat during the dietary intervention but not with other measures of adherence. Higher baseline restrained eating was associated with greater 12-month reductions in weight, waist circumference, body fat and lean mass. Women randomized to dietary intervention had significant reductions in binge eating (- 23.7%, p = 0.005 vs. control), uncontrolled eating (- 24.3%, p < 0.001 vs. control), and emotional eating (- 31.7%, p < 0.001 vs. control) scores, and a significant increase in restrained eating (+ 60.6%, p < 0.001 vs. control); women randomized to diet + exercise reported less uncontrolled eating (- 26.0%, p < 0.001 vs. control) and emotional eating (- 22.0%, p = 0.004 vs. control), and increased restrained eating (+ 41.4%, p < 0.001 vs. control). Women randomized to exercise alone had no significant change in eating behavior scores compared to controls. CONCLUSIONS: A dietary weight loss intervention helped women modify eating behaviors. Future research should investigate optimal behavioral weight loss interventions for women with both disordered eating and obesity. TRIAL REGISTRATION: NCT00470119 (https://clinicaltrials.gov).

RESUMEN

Objectives: Latinas are less likely than non-Latina Whites (NLW) to utilize mammographic screening and are more likely to be diagnosed with late-stage breast cancer. Here, we examine the effects of county-level factors on guideline-concordant breast-cancer screening behaviors in Latinas and NLWs. Design: Latinas (N=108) and NLW women (N=132) aged >40 years, residing in two adjacent rural, medically underserved counties in eastern Washington State, completed a baseline questionnaire on mammography utilization and demographics. Main Outcome Measures: Differences in socioeconomic variables and knowledge of screening practices were examined by ethnicity and county of residence. Predictors of having had a mammogram within the past two years were analyzed using multivariate logistic regression. Results: Ethnicity was not associated with having a guideline-concordant mammogram; however, age (odds ratio [OR]=1.04, 95%CI:1.01-1.08); having >12 years of education (OR=2.09, 95%CI:1.16-3.79); having a regular clinic for health care (OR=2.22, 95%CI:1.05-4.70); having had a prior clinical breast exam (OR=5.07, 95%CI:1.71-15.02), and county of residence (OR=2.27, 95%CI:1.18-4.37) were all associated with having had a guideline-concordant mammogram. Conclusions: County of residence and having had a prior CBE were strong predictors of screening utilization. Community-level factors in medically underserved areas may influence screening patterns.

RESUMEN

PURPOSE: Tumor necrosis factor-α (TNF-α), peroxisome proliferator-activated receptor-γ (PPARγ), and insulin receptor substrate-1 (IRS-1) are associated with obesity, insulin resistance, and inflammation. Few data exist on associations between polymorphisms in these genes and mortality in breast cancer survivors. METHODS: We investigated associations between TNF-α -308G > A (rs1800629); PPARγ Pro12Ala (rs1801282); and IRS-1 Gly972Arg (rs1801278) polymorphisms and anthropometric variables, circulating levels of previously measured biomarkers, and tumor characteristics in 553 women enrolled in the Health, Eating, Activity, and Lifestyle Study, a multiethnic, prospective cohort study of women diagnosed with stage I-IIIA breast cancer between 1995 and 1999 (median follow-up 14.7 years).  Using Cox proportional hazards models adjusted for possible confounders, we evaluated associations between these polymorphisms and mortality. RESULTS: Carriers of the PPARγ variant allele had statistically significantly lower rates of type 2 diabetes (P = 0.04), lower BMI (P = 0.01), and HOMA scores [P = 0.004; non-Hispanic White (NHWs) only]; carriers of the TNF-α variant A allele had higher serum glucose (P = 0.004, NHW only); and the IRS-1 variant was associated with higher leptin levels (P = 0.003, Hispanics only). There were no associations between any of the polymorphisms and tumor characteristics. Among 141 deaths, 62 were due to breast cancer. Carriers of the TNF-α-variant A allele had a decreased risk of breast-cancer-specific mortality [hazard ratio (HR) 0.30; 95% confidence interval (CI) 0.10-0.83] and all-cause mortality (HR 0.51; 95% CI 0.28-0.91). CONCLUSIONS: Neither the PPARγ nor the IRS-1 polymorphism was associated with mortality outcome. The TNF-α -308 G > A polymorphism was associated with reduced breast-cancer-specific and all-cause mortality.

RESUMEN

Most evidence on breast cancer screening accuracy derives from high income countries. We evaluated screening accuracy and factors related to program implementation in Bogota, Colombia. Between 2008 and 2012 participants underwent clinical breast examination (CBE) and mammography. Positive results underwent histological verification. Adherence to screening protocols was analyzed. Sensitivity, specificity, and predictive values were estimated and adjusted by overdiagnosis. Impact of alternative screening algorithms on follow-up was explored, including combined screening tests and modified coding systems for mammography. In total, 7436 women aged 50-69 were enrolled; 400 discontinued and 1003 non-compliant with screening protocols. 23 cancer cases were diagnosed. Mammography sensitivity and specificity were 78.3% (95%CI 77.3-99.3) and 99.4% (95%CI 99.2-99.6). CBE sensitivity was 39.1% (95%CI 37.9-40.3) and specificity 83.4% (95%CI 82.6-84.3). Parallel mammography and CBE showed the highest sensitivity (95.6%) and combined as serial tests the lowest (positive CBE followed by mammography 13.0%). A simplified coding system for mammography (recall/no-recall) had 6.3% of positive results and a minor reduction in specificity compared with standard mammography, but reported the best balance between recall rates and screening protocol compliance. Call-backs had high rates of loss-to-follow-up; thus, alternative screening algorithms might help increase screening compliance and follow-up in low and middle income countries, particularly in populations with poor screening history and low access to health services.

RESUMEN

BACKGROUND: Hispanics bear some of the highest burden of the obesity epidemic and the disparities gap is bigger among Hispanics in rural communities. This mixed methods study examined the objective and subjective assessment of food availability and food access in four rural, agricultural, and predominantly Hispanic communities. METHODS: In this convergent parallel mixed methods study, we used the Nutrition Environment Measures Survey (NEMS) of Food Stores and Restaurants to objectively assess 57 food stores and 69 restaurants in four rural agricultural communities in Washington State. To complement the objective assessment findings, we conducted semi-structured interviews with 32 community residents. The data were collected from 2013 to 2014. Frequencies and means were calculated for quantitative data and content analysis conducted for interview data. RESULTS: Participants (n = 32) had a mean age of 35.6 (SD 6.2) years, were mostly women, uninsured, low income, and had less than a high school education. Grocery and convenience stores had low NEMS composite scores indicating low overall availability of food items, low quality, and high food prices. Composite scores for sit-down restaurants, fast casual restaurants, and fast-food restaurants were similarly low in all four towns indicating limited availability of healthier options. Semi-structured interviews revealed participants perceived high availability and accessibility of quality fresh produce. Most participants reported eating out regularly several times a week, frequenting restaurant chains that serve buffets or fast foods, and allowing children to make decisions regarding their own food choices. CONCLUSIONS: Community members' perception of food availability and food access may be different from the objective assessment of food environment. This information can be used to inform community-wide interventions to address food environment in these rural communities.
