Post-Austronesian migrational wave of West Polynesians to Micronesia.

This study examines Y-chromosome and mtDNA markers in the population of the island of Kiritimati in the context of geographically targeted reference populations from the Pacific. Kiritimati derives its population from the atoll islands of the Gilbert Archipelago and representsa geographicaltransitional region between Micronesia, Polynesia and Melanesia that likely played a critical role during theAustronesian expansion. The large presence(84.1%)of individuals withO-M175, O2a-M324 and O2a2b-P164 sub-haplogroups, 69.9% being O2a2b-P164, the Y-STR homogeneity within O2a2b-P164 and the very recent age of the sub-haplogroup(363-548 years ago)inKiritimati suggestthe arrival ofa genetically homogenous population to the Gilberteses followed by a population expassion.The close Y-STR haplotype affinities with profiles from the Samoa and Tonga Archipelagos point to an unprecedented massive post-Austronesian expansionexodus from West Polynesia.Contrasting the abundance of AustronesianO2a2b-P164 sub-haplogroup, the most abundantMelanesian/Papuansub-haplogroup,C-M130is present at a frequency of 13.5%. Thenetwork topology suggests that C-M130 arrived to theKiribati Archipelago from West Polynesia, specifically from West Samoa, Tonga and/or Tutuila subsequent to the Austronesian expansion about 832-1408 years ago. The haplotype affinities withinO2a2b-P164 argue for anoriginal source in Taiwan and its dispersal to West Polynesia and then to Southeast Micronesia. The present investigation provides an understanding of the genetic composition and complex migration history of an understudied region of the Pacific and provides evidence for recent dispersals towards Micronesia from West Polynesia subsequent to the initial Austronesian expansion.

Repeated introductions and intensive community transmission fueled a mumps virus outbreak in Washington State.

In 2016/2017, Washington State experienced a mumps outbreak despite high childhood vaccination rates, with cases more frequently detected among school-aged children and members of the Marshallese community. We sequenced 166 mumps virus genomes collected in Washington and other US states, and traced mumps introductions and transmission within Washington. We uncover that mumps was introduced into Washington approximately 13 times, primarily from Arkansas, sparking multiple co-circulating transmission chains. Although age and vaccination status may have impacted transmission, our data set could not quantify their precise effects. Instead, the outbreak in Washington was overwhelmingly sustained by transmission within the Marshallese community. Our findings underscore the utility of genomic data to clarify epidemiologic factors driving transmission and pinpoint contact networks as critical for mumps transmission. These results imply that contact structures and historic disparities may leave populations at increased risk for respiratory virus disease even when a vaccine is effective and widely used.

Acculturation and Cancer Risk Behaviors among Pacific Islanders in Hawaii.

Background: To communicate research to the public, the National Cancer Institute developed the Health Information National Trends Survey (HINTS). However, as with most national health surveillance, including the Behavioral Risk Factor Surveillance System, HINTS data are not sufficient to address unique demographic subpopulations such as US Pacific Islanders (PIs). National sampling methods do not adequately reach participants from small, medically underserved populations. Aim: This study aims to document the cancer-relevant knowledge, attitudes, behaviors, and information-seeking practices of PIs in Hawaii (HI). Methods: We conducted a cross-sectional survey during 2017-2018 of Native Hawaiians, Chuukese, and Marshallese in HI using Respondent Driven Sampling (RDS) to recruit these geographically diffuse groups. The modified HINTS survey included questions about cancer knowledge, attitudes and behaviors, health communications, and cultural practices. Results: A total of 515 Native Hawaiians, 305 Chuukese, and 180 Marshallese completed the survey. Differences were found across a variety of cancer-related attitudes, knowledge, and behaviors. These groups also differed regarding acculturation, health locus of control, and trust in medical professionals. Native Hawaiians were significantly more acculturated (P=.0001) than Chuukese or Marshallese and more likely to smoke cigarettes (P=.0001). Among participants aged >50 years, we found no significant differences across ethnic groups (P=.30) for those completing a colon cancer screening (37%). However, only 27% were referred to screening by a physician. Conclusions: Cancer prevention programs are greatly needed for PIs in HI. This study provides knowledge concerning the efficiency of RDS to recruit participants, and the role of culture in communications influencing cancer risk behaviors, which may be generalizable to migrant PIs in the United States.

Cultural Considerations for Conducting the Health Information National Trends Survey with Micronesian Communities: Lessons from a Qualitative Study.

A critical barrier to addressing health disparities among minorities is the lack of data, particularly on Pacific Islanders. Typically, national health surveillance systems do not have the resources to ensure proper representation of these small population groups. This study reports factors that guided the cultural adaptation and administration of the National Cancer Institute's Health Information Trends National Survey (HINTS) for a United States-dwelling Pacific Islander population in Hawai'i. To adapt the survey, four focus groups were conducted with 32 purposively-selected Micronesian migrants. Themes on health, healthcare barriers, cancer and methods to implement the survey were extracted from the analyses of the focus group narratives. Key cultural factors were identified that impact health practices, including religious and cancer fatalism, racism, health locus of control and other barriers. Using information from the focus group participants, the HINTS questionnaire was modified and the survey was implemented. The survey data provided will inform the future delivery of health promotion strategies for this unique medically underserved population.

Evolving Palliative Care Practices among Marshall Islanders in Hawai'i: Generational Comparisons.

Little is known about Marshallese palliative care practices. We explored traditional and contemporary Marshallese palliative care practices and examined generational differences. We performed three focus groups in 2011-2012 among Marshall Islanders in Hawai'i. A native speaking interpreter assisted group facilitators. Data were analyzed using classical thematic triangulation methods to identify specific Marshallese palliative care practices, the effect of economic and social challenges in Hawai'i, and generational differences comparing young and old. Nineteen persons (10 men and 9 women, youth aged 17-27 years, and elders as defined in Marshallese culture, aged 46-79) participated. A "good death" was defined as "peaceful and pain free," occurring from natural causes. Factors associated with a "good death" included gathering of family to absolve conflicts, and proper and timely cultural practices. Factors associated with "bad deaths" included young age, active suffering, accidents, suicides, "black magic/curses," or lack of timely or proper burial. Comparing generational differences, older Marshallese had differing opinions regarding preferred place of death, burial site, cultural practice preservation, artificial prolongation of life, and cremation. Barriers included mortuary fees, cost of transporting bodies, United States (US) government policies, and wait times for death certificates. Many cultural factors contribute to "good" or "bad" deaths. Attitudes toward palliative care practices differ by generation. Having previously documented different approaches by Yapese, a generalized "one size fits all" approach to Micronesians is inappropriate. Overcoming identified barriers may facilitate practices necessary for a good death in Micronesian populations in their home nations and as they migrate to communities throughout the US.

Eliciting culturally and medically informative family health histories from Marshallese patients living in the United States.

The United States (U.S.) resident Marshallese population is growing rapidly. Subsequent to this growth, Marshallese patients experience language and cultural barriers when attempting to access medical care in the U.S. This study: (a) documents how the Marshallese refer to biological and adopted family members; (b) identifies barriers encountered by Marshallese when seeking medical care; and (c) describes effective communication strategies for healthcare providers to use when treating Marshallese patients. Six key informant interviews were conducted in English with bicultural (U.S. and native Marshallese) informants, the majority of whom were women who worked in a healthcare setting. Participants were recruited through the Center for Pacific Islander Health in Arkansas and through personal contacts within the Marshallese community. Based on the study findings, examples of how providers can make genetic services more accessible and meaningful for Marshallese patients are also provided. This study is particularly relevant to genetic counselors as the number of Marshallese patients and families needing their services is growing.

'Just doing the best we can': health care providers' perceptions of barriers to providing care to Marshallese patients in Arkansas.

Introduction: Marshallese migrating to the United States encounter challenges in accessing health care. Previous literature has investigated Marshallese participants' perceptions of the barriers they face in accessing health care. For this study, health care providers managing the care of Marshallese patients were interviewed to understand the providers' perception of barriers that their Marshallese patients encounter. Methods: A qualitative research design was utilized to explore health care providers' perceptions of and experiences with the barriers faced by their Marshallese patients when accessing the US health care system. Results: The primary barriers identified were: (1) economic barriers; (2) communication challenges; (3) difficulty understanding and navigating the western health care system; and (4) structural and system barriers. Conclusion: This study provides insight on the barriers Marshallese patients face in accessing health care as well as the barriers providers face in delivering care to Marshallese patients. A better understanding of these barriers can help health care providers and educators to begin initiating improvements in the delivery of care to Marshallese patients.

Diabetes self-management education exposure and glycated haemoglobin levels among Marshallese participants in a randomized controlled study.

AIMS: A randomized control trial (RCT) of diabetes self-management education (DSME), undertaken by a community-based participatory research (CBPR) partnership between the University of Arkansas for Medical Sciences (UAMS) and the Marshallese community in Arkansas. The RCT examined the effect of hours of intervention exposure, with the hypothesis that increased exposure is one reason the Adapted-Family DSME was found to be more effective than the Standard DSME. METHODS: Some 221 Marshallese with type 2 diabetes were randomized to an Adapted-Family DSME group (in-home setting) (n = 110) or a Standard DMSE group (community setting) (n = 111). The Adapted-Family DSME included 10 h of education that covered the core self-care elements recommended by the American Diabetes Association (ADA) and American Association of Diabetes Educators' (AADE) recommendations. The Standard DSME included 10 h of intervention with all ADA and AADE core elements. RESULTS: The number of hours of intervention exposure in the Adapted-Family DSME arm (mean = 8.0; median = 10.0) was significantly higher than the number of hours of intervention received in the Standard DSME arm (mean = 1.5; median = 0.0). As hypothesized, higher exposure was associated with a significant reduction in HbA1c in a model including only study arm and exposure (P = 0.01), and in a model including study arm, exposure, and all demographic variables (P = 0.046). CONCLUSIONS: This finding is consistent with previous reviews that showed increased exposure to DSME produced improved glycaemic control and ≥ 10 h of DSME produces clinically meaningful reductions in HbA1c .

A Community-Based Participatory Approach to Promote Healthy Eating Among Marshallese.

This article describes changes made to the menu served during the 2015 Marshallese May Day celebration in Northwest Arkansas, an annual Marshallese community event. The menu changes were part of a community-based participatory collaborative to improve nutrition and health in the Marshallese community. The 2015 May Day menu significantly reduced the 2014 May Day menu amount of calories, fat, carbohydrates, sodium, and cholesterol of foods offered by incorporating healthier ingredients and reducing portion sizes. Compared to the 2014 May Day menu, the total caloric value of the revised menu was reduced by more than 63%, declining from 1369 calories to 499 calories. The menu change affected an estimated 1,800 Marshallese in attendance for the 2015 May Day celebration. The successful implementation of the menu changes, which resulted in reductions in calories, fat, carbohydrates, sodium, and cholesterol offered to participants demonstrates the effectiveness of community-based participatory approaches in the implementation of policy, systems, and environmental strategies to promote health.

Adverse Pregnancy and Neonatal Outcomes Among Marshallese Women Living in the United States.

Objective Despite heterogeneity among Pacific Islanders, most studies aggregate them regardless of origin. Thus, limited information is available about perinatal outcomes among various subgroups of Pacific Islanders in the United States, including immigrants from the Republic of the Marshall Islands. We sought to evaluate perinatal outcomes among Marshallese women. Methods We conducted a cross-sectional study of women with at least one singleton live birth between 1997 and 2013 in two Arkansas counties using birth certificate data from the Arkansas Department of Health. Unadjusted and adjusted prevalence ratios (PR) and 95% confidence intervals (CI) were calculated from modified Poisson regression models. Results Of the 91,662 singleton births in both counties during the study period, 2488 were to Marshallese women. In adjusted analyses, Marshallese women had higher prevalence of "other medical risk factors" (PR = 1.47; 95% CI 1.30, 1.65) than NH White women. Marshallese women had higher rates of precipitous labor and fetal distress during labor compared to NH White women (PR = 2.65; 95% CI 2.22, 3.17 and 1.89; 95% CI 1.62, 2.21, respectively). Marshallese were also more likely to have tocolysis (PR = 1.43; 95% CI 1.16, 1.76), forceps (PR = 1.68; 95% CI 1.16, 2.43) or vacuum (PR = 1.89; 95% CI 1.60, 2.22) used in delivery and cesarean section (PR = 1.13; 95% CI 1.01, 1.27). Marshallese infants had higher rates of anemia (PR = 3.10; 95% CI 2.01, 4.77), birth injury (PR = 2.13; 95% CI 1.50, 3.03), assisted ventilation < 30 min (PR = 2.11; 95% CI 1.64, 2.71), preterm birth (PR = 1.67; 95% CI 1.50, 1.83), and small-for-gestational age (PR = 1.25; 95% CI 1.12, 1.39) than NH White infants. Conclusions Marshallese women and infants had higher rates of adverse perinatal outcomes compared to their NH White counterparts. Additional studies are needed to determine if perinatal outcomes among the Marshallese differed from other Pacific Islander subgroups.

Distressing encounters in the context of climate change: Idioms of distress, determinants, and responses to distress in Tuvalu.

Across the globe there is a critical need for culturally informed and locally valid approaches to mental health assessment and intervention, particularly among disadvantaged and marginalized populations. To be optimally effective, such approaches must be informed by a sound understanding of locally relevant idioms of distress and its determinants, including those caused or exacerbated by global power disparities and structural inequities. Climate change, arising due to anthropogenic sources located predominantly in industrialized nations, is one potential determinant of distress having disproportionate adverse impacts on already marginalized populations. The present study formed part of a broader project examining the intersections of culture, climate change, and distress in the Polynesian nation of Tuvalu - a focal point of global concern over the human costs of climate change. The study explored determinants and idioms of distress and culturally prescribed responses to coping with distress. Results are based on fieldwork conducted in 2015 entailing semi-structured interviews with 16 key informants and 23 lay residents of Funafuti atoll, recruited using maximal variation purposive sampling. Findings are examined in consideration of the unfolding impacts of climate change and the threat it portends for the future, both of which were identified as salient determinants of distress, in keeping with theorized relationships between climate change and mental health. The study underscores the necessity of attending to the relationships between global forces, local cultures, and individual experiences of distress, as efforts to provide access to culturally informed social and mental health services expand globally.

Ethical Dilemmas Encountered by Health Care Providers Caring for Marshallese Migrants in Northwest Arkansas.

Marshallese migrating to the United States face numerous challenges in accessing health care and managing illness and chronic disease. This study explores health care providers' perceptions of and experiences with ethical dilemmas as they care for Marshallese patients. Utilizing a qualitative research design, we interviewed 21 providers to explore the ethical dilemmas they encountered while treating Marshallese patients. We used the framework of bioethical principlism to categorize and describe the ethical dilemmas reported by those providers. When explicitly asked whether they experienced such situations, approximately half (10/21) affirmed that they had, and analysis of the qualitative data indicated that all interviewees described an ethical dilemma at least once during their interviews. We characterized providers' ethical dilemmas in terms of conflicts that arise when prioritizing different ethical principles in the care of this complex patient population, including the principles of respect for autonomy, nonmaleficence, beneficence, and justice.

Mental Health Status, Need, and Unmet Need for Mental Health Services Among U.S. Pacific Islanders.

OBJECTIVE: This study examined the mental health status, need for services, and unmet need of community-dwelling Native Hawaiian and other Pacific Islanders (NHPI). METHODS: Survey data were collected from 223 NHPI adults of Samoan or Marshallese heritage. Surveys were translated into Samoan and Marshallese by using back-translation, with feedback from cultural experts. Severity of depression, anxiety, and alcohol use were measured, as were perceived need for and avoidance of, or delay in, seeking mental health services. Logistic regressions calculated adjusted odds ratios for past-year perceived need for services and avoidance or delay of needed services, controlling for depression, anxiety, and alcohol use. RESULTS: Participants' screened prevalence of major depression, generalized anxiety disorder, and alcohol use disorder was 21%, 12%, and 22%, respectively. In the past year, 35% and 26% of participants reported needing services and avoiding or delaying needed services, respectively. Urban Samoan and rural Marshallese participants did not differ significantly in measures of depression, anxiety, or alcohol use, even though the groups had significant demographic differences. Female gender and greater familiarity-contact with persons with mental illness were significant predictors of both reporting service need and reporting avoiding or delaying services. CONCLUSIONS: Community-dwelling NHPIs reported a heavy burden of depression, anxiety, and alcohol use, and high perceived need for services, yet low levels of help-seeking. The large unmet need in the sample suggests that a gap may exist between service need and engagement in U.S. NHPI communities that could be targeted with culturally tailored approaches that promote engagement in care.

Comparative Effectiveness and Maintenance of Diabetes Self-Management Education Interventions for Marshallese Patients With Type 2 Diabetes: A Randomized Controlled Trial.

OBJECTIVE: Marshallese adults experience high rates of type 2 diabetes. Previous diabetes self-management education (DSME) interventions among Marshallese were unsuccessful. This study compared the extent to which two DSME interventions improved glycemic control, measured on the basis of change in glycated hemoglobin (HbA1c). RESEARCH DESIGN AND METHODS: A two-arm randomized controlled trial compared a standard-model DSME (standard DSME) with a culturally adapted family-model DSME (adapted DSME). Marshallese adults with type 2 diabetes (n = 221) received either standard DSME in a community setting (n = 111) or adapted DSME in a home setting (n = 110). Outcome measures were assessed at baseline, immediately after the intervention, and at 6 and 12 months after the intervention and were examined with adjusted linear mixed-effects regression models. RESULTS: Participants in the adapted DSME arm showed significantly greater declines in mean HbA1c immediately (-0.61% [95% CI -1.19, -0.03]; P = 0.038) and 12 months (-0.77% [95% CI -1.38, -0.17]; P = 0.013) after the intervention than those in the standard DSME arm. Within the adapted DSME arm, participants had significant reductions in mean HbA1c from baseline to immediately after the intervention (-1.18% [95% CI -1.55, -0.81]), to 6 months (-0.67% [95% CI -1.06, -0.28]), and to 12 months (-0.87% [95% CI -1.28, -0.46]) (P < 0.001 for all). Participants in the standard DSME arm had significant reductions in mean HbA1c from baseline to immediately after the intervention (-0.55% [95% CI -0.93, -0.17]; P = 0.005). CONCLUSIONS: Participants receiving the adapted DSME showed significantly greater reductions in mean HbA1c immediately after and 12 months after the intervention than the reductions among those receiving standard DSME. This study adds to the body of research that shows the potential effectiveness of culturally adapted DSME that includes participants' family members.

"You Want to Give the Best Care Possible, and You Know When They Leave Your Pharmacy, You Didn't Give the Best Care Possible Most of the Time": Pharmacist- and Community Health Worker-Identified Barriers and Facilitators to Medication Adherence in Marshallese Patients.

BACKGROUND: The Marshallese experience high rates of chronic diseases including hypertension and diabetes. Medication adherence is crucial to successful disease management, and healthcare providers play a crucial role in assisting their patients with medication adherence. METHODS: A qualitative study design was used with individual interviews and focus groups with pharmacists and community health workers (CHWs) serving the Marshallese community in Northwest Arkansas. Participants were asked about their experiences with and perceptions of barriers and facilitators to medication adherence among Marshallese adults in Northwest Arkansas. RESULTS: Eight pharmacists and nine CHWs were interviewed. Five themes emerged regarding barriers to medication adherence: (1) financial, (2) transportation, (3) language, (4) health literacy and understanding of Western medicine, and (5) mistrust. Four themes emerged regarding facilitators to medication adherence: (1) in-depth patient education strategies, (2) efforts to address the language barrier, (3) family engagement, and (4) public transportation and prescription home delivery. DISCUSSION: Pharmacists and CHWs identified the same barriers to medication adherence, which are consistent with those documented in previous studies. Pharmacists also reported distress over their inability to confirm Marshallese patient understanding in relation to the use of prescribed medications.

Social and economic influences on infant and child feeding practices in a Marshallese community.

OBJECTIVE: The present study aimed to examine the key influences on infant and child feeding practices among a Marshallese community at each social ecological level. It is the first study to examine the key influences on infant and child feeding practices with Marshallese immigrant women in the USA and helps fill a gap in the previous literature that has included other immigrant women. DESIGN: Community-based participatory research design with twenty-seven participants taking part in four qualitative focus groups. SETTING: The study took place within the Marshallese community in Arkansas, USA.ParticipantsParticipants included Marshallese women with children aged 1-3 years and/or caregivers. Caregivers were defined as someone other than the parent who cares for children. Caregivers were often older women in the Marshallese community. RESULTS: There were five primary themes within multiple levels of the Social Ecological Model. At the intrapersonal level, mothers' and caregivers' autonomy emerged. At the interpersonal level, child-led and familial influences emerged. At the organizational level, health-care provider influences emerged; and at the policy level, the Special Supplemental Nutrition Program for Women, Infants, and Children emerged as the most salient influence. CONCLUSIONS: Marshallese immigrant women's infant and child feeding practices are influenced at intrapersonal, interpersonal, organizational and policy levels. Understanding these multidimensional influences is necessary to inform the creation of culturally tailored interventions to reduce health disparities within the Marshallese community.

Using CBPR to address health disparities with the Marshallese community in Arkansas.

CONTEXT: Arkansas currently has the largest Marshallese community in the continental US. The limited research available demonstrates that Marshallese have significant health disparities, with higher rates of obesity, diabetes, cardiovascular disease and infectious diseases than the US population. OBJECTIVES: The purpose of this paper is 2-fold: (1) to describe the formation and capacity building efforts of a community-based participatory research partnership with the Marshallese community in Arkansas and (2) to describe key findings and lessons learned from 5 years of collaborative research. METHODS: A community-based participatory research approach was implemented to build alliances and improve health disparities in a Marshallese community. RESULTS: Overarching lessons learned from collaboration with the Marshallese community include the: (1) Intensive involvement of Marshallese from multiple sectors of the community and in multiple roles in the research process, (2) Importance of interprofessional teams, (3) Importance of church, (4) Consideration of sex, (5) Importance of family and definition of family, (6) Talk Story and qualitative methods and the (7) Importance of cultural humility. CONCLUSIONS: This research helps fill important gaps in documenting the health disparities and interventions to address those disparities in the Marshallese community.

Chuukese Patients, Dual Role Interpreters, and Confidentiality: Exploring Clinic Interpretation Services for Reproductive Health Patients.

This exploratory study analyzes limited English proficient (LEP) Chuukese patients' perspectives on dual-role interpreters in Guam and Chuuk. Methods included ethnographic observations of encounters with health care workers (HCWs) and 225 female Chuukese patients seeking reproductive healthcare in community health clinics: 126 women in Guam and 99 women in Chuuk. Ethnographic observations were supplemented by semi-structured interviews with 26 HCWs, and life history interviews with 15 Chuukese transnational migrant women. Notes from interview transcripts and observations were analyzed using critical interpretive and grounded theory. Findings demonstrated that Chuukese LEP patients need and at times want interpreters in order to understand their healthcare visits. In the absence of professional interpreters, ad-hoc interpreters (family interpreters and employees of the clinic) are an important resource. However, social and cultural concerns with community confidentiality influenced patient trust of staff interpreters. This lack of trust can limit access to health care overall, as some patients may avoid seeking care to prevent their confidential health information being disclosed. These complexities in interpretation must be considered in order for clinics to provide optimal care for the communities they serve.

The use of home brew in Pacific Islands countries and territories.

This review examines what is known about the production and use of home brew in the Pacific Islands countries and territories. Data collection involved interviews of 78 men and women from the Marshall Islands, Papua New Guinea, Toga, and Tuvalu. The interviews were conducted in 2013 by local interviewers. The questions fell into four key areas: people's history of home-brew consumption, the reasons for home-brew use, the effects of home brew, and people's perceptions about home brew. An open ethnographic approach revealed that males are the main consumers of home brew, that home brew is consumed in private venues by those with low socioeconomic status, and that there are positive and negative outcomes associated with the use of home brew. Finally, policy implications of the findings are included in this article.
