External relationships as implementation determinants in community-engaged, equity-focused COVID-19 vaccination events.

Background: While relationships and connectedness among organizations have been included in implementation theories, models, and frameworks, the increased attention to health equity in implementation science raises the urgency of understanding the role of relationships external to the implementing organization. This paper addresses this gap through an exploration of the role of external relationships in community-based, equity-focused interventions. Methods: This study focuses on an equity-focused, community-based COVID-19 vaccination intervention in Arkansas, drawing upon long-term community-engaged relationships among University of Arkansas for Medical Sciences and the Hispanic and Marshallese Islander communities. We used an exploratory qualitative descriptive design to examine barriers and facilitators to implementation of COVID-19 vaccination events analyzing in-depth qualitative interviews with implementation team members (n = 17). Results: All participants described pre-existing relationships among the implementing organization, partner organizations, and communities as a key implementation determinant for this equity-focused program. At the inter-organizational level, external relationships included formal connections and informal relationships among staff (e.g., communication channels from prior partnerships). At the individual level, strong external relationships with the community were facilitators leveraging long-term engagement, community familiarity, and staff from the communities of focus. Strong external relationships facilitated program reach in underserved communities through three mechanisms: (1) reduced time required to establish functional working relationships among partners; (2) accessibility and cultural congruence of health services; and (3) increased trust among community members. Barriers to implementation also existed in external relationships, but had less influence than facilitators. Conclusions: Achieving health equity in implementation science requires greater understanding of external relationships as implementation determinants. This exploratory study makes a significant contribution to the literature by describing the types of external relationships that facilitate equitable implementation and identifying the mechanisms through which they may work. We argue that approaches to community engagement drawn from community-engaged research approaches may be useful, as these processes require investment in building/maintaining formal and informal organizational and interpersonal relationships. Further research is needed to understand connections among external relationships and other implementation determinants.

COVID-19 vaccine hesitancy among Marshallese in Northwest Arkansas (USA).

Background: COVID-19 has disproportionately affected Pacific Islander communities, with disparities in the prevalence of infection, serious illness, and death compared to non-Hispanic whites in the US. Marshallese Pacific Islanders face significant COVID-19 disparities. Design and methods: This exploratory study aimed to understand Marshallese community attitudes about the COVID-19 vaccine to identify and implement culturally relevant strategies to encourage vaccine uptake. Data were collected from 17 participants in three focus groups. Results: Using content analysis, researchers identified two global themes: (1) barriers to vaccination and (2) facilitators of COVID-19 vaccine uptake. Within these themes, participants described fear, lack of knowledge about vaccines, negative perceptions of the COVID-19 vaccine, health concerns, and transportation as barriers to vaccination. Participants described several factors influencing vaccine behavior, including location of and personnel at vaccine clinics, vaccine experiences, the need for trusted information, positive perceptions, cultural leaders, and mandates. Conclusions: The qualitative study makes a significant contribution as the first to report community perceptions and experiences related to the COVID-19 vaccine in Marshallese participants' own words. Findings show that cultural influencers and brokers are crucial bridges for public health messaging related to COVID-19 vaccination targeted to this vulnerable and underserved population. Culturally appropriate and effective public health messaging can help achieve vaccine equity and improve COVID-19-related health disparities in the Marshallese community.

Undiagnosed hypertension and type 2 diabetes mellitus among Marshallese adults in the Republic of the Marshall Islands.

Background: Given the lack of healthcare access in the Republic of the Marshall Island (RMI) and the potential for complications related to type 2 diabetes mellitus (T2DM) and hypertension, it is crucial to examine these conditions among Marshallese in the RMI. Objectives: This study aims to identify the proportion of Marshallese adults in the RMI with undiagnosed T2DM and hypertension. Design: Using a community-based participatory research approach, screening events were conducted at 20 churches in Majuro Atoll. Methods: Participants completed a questionnaire and biometric data measures, including hemoglobin A1c and blood pressure. Results: Among participants with blood pressure data (N = 528), 11.9% had readings indicative of hypertension, and 38.1% were undiagnosed. Among participants with hemoglobin A1c (HbA1c) data (N = 450), 45.3% had readings indicative of T2DM, and 39.2% were undiagnosed. Conclusion: This study utilized a community-based participatory research approach that promotes equitable and ethical research. Results reaffirm the need to identify strategies for increasing healthcare access and for research to address health disparities in the RMI.

Study using data collected during health screenings in the Republic of the Marshall Islands (RMI) to identify the number of Marshallese people with undiagnosed diabetes and/or high blood pressure The Republic of the Marshall Island (RMI) is a nation located in the Pacific Ocean between Hawai'i and New Zealand. The RMI was the location of nuclear testing by the United States (US) in the 1940s and 1950s, changing the diet of Marshallese people, and leading to a high rate of type 2 diabetes and high blood pressure. However, healthcare in the RMI is less available than in the US, meaning Marshallese people may not be aware if they have these chronic conditions. The goal of our study was to determine the prevalence of undiagnosed type 2 diabetes and high blood pressure among participants in church-based health screenings in the RMI. The study team found that 38.1% of people with readings indicating type 2 diabetes and 39.2% of people with readings indicating high blood pressure were undiagnosed. These results show there is additional work needed in the RMI to increase access to healthcare services.

Moana: Alternate surveillance for COVID-19 in a Unique Population (MASC-UP).

Objective: Create a longitudinal, multi-modal and multi-level surveillance cohort that targets early detection of symptomatic and asymptomatic COVID-19 cases among Native Hawaiian and Pacific Islander adults in the Continental US and identify effective modalities for participatory disease surveillance and sustainably integrate them into ongoing COVID-19 and other public health surveillance efforts. Materials and methods: We recruited cohorts from three sites: Federal Way, WA; Springdale, AR; and remotely. Participants received a survey that included demographic characteristics and questions regarding COVID-19. Participants completed symptom checks via text message every month and recorded their temperature daily using a Kinsa smart thermometer. Results: Recruitment and data collection is ongoing. Presently, 441 adults have consented to participate. One-third of participants were classified as essential workers during the pandemic. Discussion: Over the past 18 months, we have improved our strategies to elicit better data from participants and have learned from some of the weaknesses in our initial deployment of this type of surveillance system. Other limitations stem from historic inequities and barriers which limited Native Hawaiian and Pacific Island representation in academic and clinical environments. One manifestation of this was the limited ability to provide study materials and support in multiple languages. We hope that continued partnership with the community will allow further opportunities to help restore trust in academic and medical institutions, thus generating knowledge to advance health equity. Conclusion: This participatory disease surveillance mechanism complements traditional surveillance systems by engaging underserved communities. We may also gain insights generalizable to other pathogens of concern.

Experiences of Discrimination Among Native Hawaiians and Pacific Islanders Living in the USA.

Experiences of racism and discrimination are stressors that adversely affect the well-being of marginalized populations, including Native Hawaiians and Pacific Islanders (NHPI). However, commonly used data aggregation methods obscure information on NHPI communities and their lived experiences. The aim of our study is to understand the types and frequency of discrimination experienced by NHPI adults in the USA. The study utilized online survey data collected from 252 NHPI adults living in the USA between September and October 2021. Younger NHPI adults, those who report constantly thinking about their race/ethnicity, and those who are socially assigned a race/ethnicity that does not match their own report experiencing more types of discrimination. NHPI who constantly think about their race/ethnicity and those who are socially assigned a race/ethnicity that does not match their own report a greater frequency of discrimination. Findings indicate the need to understand the experiences of discrimination in this population.

Assessment of diabetes self-care behaviors and knowledge among Marshallese adults with type 2 diabetes in the Republic of the Marshall Islands.

AIMS: The aim of this study is to assess and document engagement in type 2 diabetes mellitus (T2DM) self-care behaviors and self-reported diabetes knowledge among Marshallese adults living in the Republic of the Marshall Islands (RMI). METHODS: The study uses data from a T2DM health screening study completed in the RMI; survey and biometric data were captured as part of the health screenings. Study objectives were examined using descriptive statistics to describe the characteristics of the participants, their diabetes self-care behaviors, and their levels of self-reported diabetes knowledge. RESULTS: Results indicate many Marshallese diagnosed with T2DM did not engage in adequate self-care behaviors, including blood sugar checks and foot examinations. Participants reported having forgone needed medical care and medication due to issues with cost and/or access, and participants reported low levels of diabetes knowledge. CONCLUSIONS: The results demonstrate the need for further work in improving engagement in diabetes self-care by Marshallese living in the RMI. Increased engagement in self-care and diabetes education programs may help Marshallese with T2DM to improve control of their glucose and avoid long-term health complications, as well as reduce costs to the healthcare system.

Pandemic-Amplified Material Hardship and Community-Led Support among Marshallese Diasporic Communities in the United States.

This article explores the experiences of Marshallese diasporic migrants in the United States (U.S.) during the COVID-19 pandemic in relation to material hardship and community-led relief efforts. Focus groups with 53 Marshallese migrants in three states revealed that material hardship, including food and housing insecurity, inadequate healthcare, and difficulty paying bills, intensified among their communities during the pandemic. In response, Marshallese community-based groups provided relief to their fellow community members, including food, cash assistance, and personal protective equipment. The findings fit a pattern of intensified hardship and community-led relief among marginalized communities in the U.S. during the COVID-19 pandemic.

Faith-based health screenings for Marshallese adults living in the Republic of the Marshall Islands: Study design and results.

Introduction: Striking health disparities exist in the Republic of the Marshall Islands (RMI). The RMI has one of the highest age-adjusted type 2 diabetes mellitus (T2DM) rates in the world (23.0%) compared to global (9.3%) and United States (US; 13.3%) rates. We conducted health screenings including clinical indicators of T2DM and hypertension among Marshallese in the RMI. Methods: Screenings were conducted at 20 churches on Majuro Atoll. Participants completed questionnaires and biometric data collection assessing glycated hemoglobin (HbA1c), blood pressure, and body mass index. Results: Screenings included 528 participants and showed a high prevalence of T2DM, obesity, and hypertension. One-third of participants were referred to the non-communicable disease clinic. The percent of adults in this study with T2DM-indicative HbA1c (48.5%) is higher than observed at the national level (23.0%). Discussion: Results highlight the need for non-communicable disease-related programs in the RMI.

Marshallese Mothers' and Marshallese Maternal Healthcare Providers' Perspectives on Contraceptive Use and Reproductive Life Planning Practices and Influences.

Pacific Islander communities experience significant maternal and infant health disparities including high maternal and infant mortality. Contraception and reproductive life planning prevent approximately one-third of pregnancy-related deaths and neonatal deaths. We report the results of formative research devoted to understanding Marshallese mothers' as well as their maternal healthcare providers' practices and influences related to contraceptive use and reproductive life planning. This study used an exploratory, descriptive qualitative design to explore Marshallese mothers' and maternal healthcare providers' practices and influences of contraception use and reproductive life planning. Twenty participants were enrolled in the study, 15 Marshallese mothers and five Marshallese maternal healthcare providers. For the Marshallese mothers, two themes emerged: (1) Reproductive Life Planning Practices and Information; and (2) Reproductive Life Planning Influences. For the Marshallese maternal healthcare providers, two themes emerged: (1) Reproductive Life Planning Practices; and (2) Reproductive Life Planning Influences. This is the first study to document Marshallese mothers' and maternal healthcare providers' practices and influences with contraceptive use and reproductive life planning. Study results will inform the development of a culturally-adapted contraception and reproductive life planning tool with an educational program for Marshallese family units and maternal healthcare providers serving Marshallese women.

A Cluster Randomized Controlled Trial Comparing Diabetes Prevention Program Interventions for Overweight/Obese Marshallese Adults.

This study compared the effectiveness of two Diabetes Prevention Program (DPP) interventions on weight loss among overweight and obese Marshallese adults. The study was a two-arm cluster randomized controlled trial conducted in 30 churches in Arkansas and Oklahoma. Marshallese adults with a body mass index ≥25 kg/m2 were eligible for the study. The study sample included 380 participants. Participants received either a faith-based adaptation of the DPP or a family-focused adaptation of the DPP, each delivered over 24 weeks. The primary outcome was weight change from baseline. Secondary outcomes included changes in Hemoglobin A1c, blood pressure, dietary intake, family support for healthy behaviors, and physical activity. Outcomes were examined longitudinally using general linear mixed effects regression models, adjusting for baseline outcomes, sociodemographic covariates, and clustering of participants within churches. Reductions in weight were small for both groups. Overall, only 7.1% of all participants lost 5% or more of their baseline body weight. There were no significant differences in weight loss between the 2 arms at 6 months (P = .3599) or at 12 months (P = .3207). Significant differences in systolic and diastolic blood pressure were found between the 2 arms at 6 months (P = .0293; P = .0068, respectively). Significant within-arm changes were found for sugar-sweetened beverage consumption and family support for both arms at both follow-ups. Both interventions achieved a modest weight loss. While even modest weight loss can be clinically significant, future research is needed to identify chronic disease prevention interventions that can successfully reduce weight for this at-risk population.

Lessons learned from the pilot family model of diabetes self-management intervention in the Republic of the Marshall Islands.

Background: The Republic of the Marshall Islands (RMI) has a high rate of type 2 diabetes mellitus (T2DM). To address the high rate of T2DM, we tested a culturally adapted family model of diabetes self-management education and support (F-DSMES). We report the results of the 12-month post-intervention data collection and describe the lessons learned from the delivery of the F-DSMES intervention. Methods: Recruitment took place in four churches in Majuro and included 10 h of content delivered over 8-10 weeks. Forty-one participants with T2DM were included. The primary study outcome was glycemic control measured by a change in HbA1c. We also conducted participant interviews to document the participant-reported barriers encountered during the F-DSMES intervention. Results: Participants did not show improvements in their biometric markers; however, participants did show improvement on multiple measures of diabetes knowledge and family support. We identified five areas to improve future interventions: 1) issues with recruitment, retention, and attendance; 2) needing help accessing information and additional healthcare provider counseling; 3) struggles with adhering to diet recommendations; 4) difficulty getting exercise, and 5) improving lessons within the intervention. Conclusion: Although the biomarker data did not show improvement, valuable information was gained to improve the development of larger-scale trials. The results provide evidence of the need for these trials and the desire of participants to continue pursuing this effort. Others doing similar work in other low-to-middle income countries will need to take into consideration the potential barriers and facilitators within participants' social and physical environments.

Cytogenetic and epigenetic aberrations in peripheral lymphocytes of northwest Arkansas Marshallese.

PURPOSE: Nuclear weapons testing in the northern Marshall Islands between 1946 and 1958 resulted in ionizing radiation (IR) exposure of the thousands of Marshallese. Furthermore, numerous islands were contaminated by radioactive fallout. Significant increases in cancer and metabolic syndrome incidences have been reported among Marshallese, and potential for further increases looms due to the latency of radiation-induced health effects. The purpose of this study was to investigate the genetic and epigenetic effects of exposure to IR that could be associated with radiation-induced disease among the Northwest Arkansas (NWA) Marshallese. MATERIALS AND METHODS: We performed analysis of chromosomal aberrations and DNA methylation based on residential and exposure history of NWA Marshallese. RESULTS: Analysis of chromosomal aberrations demonstrated higher incidence of genetic rearrangements in women with self-reported history of radiation exposure (95% CI: 0.10, 1.22; p=.022). Further clustering of study participants based on their residential history demonstrated that participants who spent substantial amounts of time (≥6 months) in the northern atolls (thus, in the proximity of nuclear tests) before 1980 had more chromosomal aberrations than their peers who lived only in the southern atolls (95% CI: 0.08, -0.95; p=.021), and that this difference was driven by women. A relationship between the time spent in the northern atolls and increase in chromosomal aberrations was observed: 0.31 increase in chromosomal aberrations for every 10 years spent at northern atolls (95% CI: 0.06, 0.57; p=.020). Finally, significant inverse correlations between the chromosomal aberrations and the extent of DNA methylation of four LINE-1 elements L1PA2, L1PA16, L1PREC1, and L1P4B were identified. CONCLUSIONS: The results of this study provide first evidence of the presence of stable genetic and epigenetic rearrangements in peripheral lymphocytes of NWA Marshallese and warrant further studies to analyze the role of radiation exposure in health disparities experienced by this Pacific Island nation.

Study protocol for family model diabetes self-management education with Marshallese participants in faith-based organizations.

Background: Culturally-appropriate family models of diabetes self-management education and support (DSMES) using community health workers (CHWs) have been shown to help address barriers to improving type 2 diabetes mellitus (T2DM) self-management for racial/ethnic minority communities; however, there is limited DSMES research among Marshallese and other Pacific Islanders. Using a community-based participatory research approach, we engaged community stakeholders to co-design a study to implement a culturally adapted family model DSMES (F-DSMES) intervention in faith-based organizations (FBOs) (i.e., churches). Methods: Using a cluster-randomized controlled trial design, we will assess the effectiveness of the F-DSMES intervention for Marshallese patients with T2DM in Arkansas and Oklahoma. Twenty-four FBOs (with 12 primary participants per FBO) will be randomized to one of two study arms: the intervention arm or the wait-list control arm. Primary participants must have at least one family member willing to attend education sessions and data collection events. The F-DSMES intervention consists of ten h of diabetes education delivered by CHWs over eight to ten weeks. Data will be collected from the intervention arm at pre-intervention (baseline), immediate post-intervention (12 weeks), and three months post-intervention. The wait-list control arm will complete a second pre-intervention data collection before receiving the intervention. The primary study outcome will be glycemic control, as measured by HbA1c. Secondary measures include glucose, weight, body mass index, blood pressure, diabetes self-management behaviors, and diabetes management self-efficacy. Conclusion: The knowledge gained from this research will inform future DSMES and other health promotion interventions conducted with Marshallese and other Pacific Islander communities.

Unified in Our Diversity to Address Health Disparities Among Asian Americans, Native Hawaiians, and Pacific Islanders.

The COVID-19 pandemic disproportionately impacted Asian Americans, Native Hawaiians, and Pacific Islanders (AA/NHPIs) in the United States. AA/NHPIs have historically been subjected to discrimination, which was exacerbated by the pandemic. To bring attention to their unique concerns, an AA/NHPI Interest Group of the National Institutes of Health Community Engagement Alliance Against COVID-19 Disparities (CEAL) was formed. This article highlights major concerns raised by the Interest Group: The pervasive and arbitrary practice of data aggregation by public health agencies and health-related researchers, the lack of culturally responsive services in the context of cultural safety, and leadership underrepresentation.

Complicity in sociology and community-based participatory research with Marshallese.

Complicity with colonialism can be reflected in a particular approach to research, whose interests it serves, and who has power or ownership over the research process. It can also be reflected in neglect, inaction or methodological erasure of groups historically subjected to domination by colonial empires. Social scientists have often failed to account for colonialism's role or the complicit role they have played. We provide a brief historical overview of colonialism in the Marshall Islands and the role social scientists-and their methodological and epistemological approaches-played in the US empire's expansion into the region. We discuss the tenets of Community Based Participatory Research (CBPR), setting the research agenda, co-direction of the research process, research team membership, collaboration challenges, and the action and outputs which have come from our team's health disparities research among the largest Marshallese population in the continental US. We argue CBPR is a promising but imperfect approach to guarding against complicity within medical sociology and situate our methodological approach within ongoing debates regarding objectivity and advocacy within sociology. We reflect on successes and shortcomings of our CBPR efforts to address health disparities among Marshallese, as well as how those successes and shortcomings overlap with questions of complicity.

Diabetes Self-Care Behaviors and Barriers to Clinical Care During COVID-19 Pandemic for Marshallese Adults.

PURPOSE: The purpose of the study was to explore experiences of Marshallese adults related to diabetes self-care behaviors during the COVID-19 pandemic. METHODS: A qualitative descriptive design was utilized to understand participants' diabetes self-care behaviors during the pandemic. Nine focus groups with 53 participants were held via videoconference and conducted in English, Marshallese, or a mixture of both languages. A priori codes based on diabetes self-care behaviors provided a framework for analyzing and summarizing participant experiences. RESULTS: Both increases and decreases in healthy eating and exercise were described, with improvements in health behaviors attributed to health education messaging via social media. Participants reported increased stress and difficulty monitoring and managing glucose. Difficulty obtaining medication and difficulty seeing their health care provider regularly was reported and attributed to health care provider availability and lack of insurance due to job loss. CONCLUSIONS: The study provides significant insight into the reach of health education campaigns via social media and provides important information about the reasons for delays in care, which extend beyond fear of contracting COVID-19 to structural issues.

Examining the Relationship Between Physical Activity and Self-Efficacy for Exercise Among Overweight and Obese Marshallese Adults.

This study examined associations between physical activity frequency and self-efficacy for exercise (SEE) among Marshallese adults in the United States. Data were collected from overweight and obese Marshallese participants (N = 378) enrolled in a Diabetes Prevention Program trial. Logistic and ordinal logistic regressions were employed to examine associations between physical activity and SEE, adjusting for covariates. SEE was significantly associated with engaging in sufficient total physical activity [odds ratio (OR) = 1.70], moderate physical activity (OR = 2.23), and vigorous physical activity (OR = 2.13). Unemployment was associated with less frequent moderate physical activity (OR = 0.59). Younger age (OR = 0.98), being male (OR = 2.67), and reporting excellent health (OR = 3.14) or good health (OR = 2.06) were associated with more frequent vigorous physical activity. Physical activity is a modifiable lifestyle behavior associated with many chronic disease disparities faced by the Marshallese community, and the study results will be useful for practitioners and researchers working to address these disparities.

Comparing community-driven COVID-19 vaccine distribution methods: Faith-based organizations vs. outpatient clinics.

Background: Minority and low socioeconomic communities may face practical barriers to vaccination, including decreased access to health care and less trust in healthcare organizations; however, few studies have focused on these barriers as the cause of differential vaccine uptake. We worked with community partners to implement and evaluate two community-driven approaches to COVID-19 vaccination distribution-through faith-based organizations (FBOs) and outpatient clinics-with a focus on understanding the differences between the populations who accessed each distribution method. Methodology: Participants who came to the vaccination locations were approached and asked to complete a survey during their 15 min post-vaccination observation period. Differences between distribution locations were examined using Chi-square tests. Results: The survey rendered 1,476 valid responses, with a total of 927 participants recruited at clinical locations and 519 at FBOs during vaccination events. There were significant differences by race/ethnicity, with distribution methods at FBOs reaching a higher proportion of Hispanic/Latino and Marshallese participants. The proportion of uninsured participants who had lower health literacy and had lower educational attainment was higher with the FBO distribution method. FBO participants were more likely to report "completely" trusting the COVID-19 vaccine. There was no significant difference between FBO and clinic participants with regard to the level of vaccine hesitancy. There were no statistically significant differences with regard to access. Conclusion: A higher proportion of Hispanic/Latino and Marshallese participants utilized FBOs for vaccination, suggesting collaborations with FBOs can potentially increase vaccination uptake among minority communities and help mitigate vaccination disparities.

COVID-19 Vaccine Willingness and Hesitancy Among Marshallese Pacific Islanders.

COVID-19 has disproportionally burdened racial and ethnic minorities. Minority populations report greater COVID-19 vaccine hesitancy; however, no studies document COVID-19 vaccine willingness among Marshallese or any Pacific Islander group, who are often underrepresented in research. This study documents United States (US) Marshallese Pacific Islanders': willingness to get the COVID-19 vaccine, willingness to participate in vaccine trials, and sociodemographic factors associated with willingness. From July 27, 2020-November 22, 2020, a convenience sample of US Marshallese adults were recruited through e-mail, phone calls, and a Marshallese community Facebook page to participate in an online survey. Of those surveyed (n = 120), 32.5% were extremely likely to get the COVID-19 vaccine; 20.8% were somewhat likely; 14.2% were unlikely or very unlikely; and 26.7% stated they did not know or were not sure. Only 16.7% stated they were willing to participate in a COVID-19 vaccine trial. Vaccine willingness was positively associated with older age, higher income, and longer US residence. Health insurance status and having a primary care provider were positively associated with vaccine willingness. Findings demonstrate within-group variation in COVID-19 vaccine willingness.
