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.

The Hawai'i NHPI Data Disaggregation Imperative: Preventing Data Genocide Through Statewide Race and Ethnicity Standards

Federal race and ethnicity data standards are commonly applied within the state of Hawai'i. When a multiracial category is used, Native Hawaiians are disproportionately affected since they are more likely than any other group to identify with an additional race or ethnicity group. These data conventions contribute to a phenomenon known as data genocide - the systematic erasure of Indigenous and marginalized peoples from population data. While data aggregation may be unintentional or due to real or perceived barriers, the obstacles to disaggregating data must be overcome to advance health equity. In this call for greater attention to relevant social determinants of health through disaggregation of race and ethnicity data, the history of data standards is reviewed, the implications of aggregation are discussed, and recommended disaggregation strategies are provided.

Food Insecurity and Blood Pressure in a Multiethnic Population

Food insecurity is a social determinant of health and is increasingly recognized as a risk factor for hypertension. Native Hawaiians bear a disproportionate burden of hypertension and known risk factors. Despite this, the relative effects of food insecurity and financial instability on blood pressure have yet to be investigated in this population. This study examines the relative effects of food insecurity and financial instability on blood pressure, controlling for potential confounders in a multiethnic sample. Participants (n = 124) were recruited from a U.S. Department of Agriculture-funded study called the Children's Healthy Living Center of Excellence. Biometrics (i.e., blood pressure, weight, and height) were measured. Demographics, physical activity, diet, psychosocial variables, food insecurity, and financial instability were assessed via self-report questionnaires. Hierarchical linear regression models were conducted. Model 1, which included sociodemographic variables and known biological risk factors, explained a small but significant amount of variance in systolic blood pressure. Model 2 added physical activity and daily intake of fruit, fiber, and whole grains, significantly improving the model. Model 3 added financial instability and food insecurity, further improving the model (R2 = 0.37, F = 2.67, p = 0.031). Food insecurity, female sex, and BMI were significantly and independently associated with increased systolic blood pressure. These results suggest a direct relationship between food insecurity and systolic blood pressure, which persisted after controlling for physical activity, consumption of fruits, fiber, and whole grains, and BMI. Efforts to reduce food insecurity, particularly among Native Hawaiians, may help reduce hypertension in this high-risk population.

Traditional and new lifestyle interventions to prevent breast cancer recurrence (TANICA): a qualitative study

PURPOSE

Breast cancer is the second cause of death from cancer in Guam and Hawai'i and disproportionately impacts Native Hawaiian, CHamoru, and Filipino women. Although a few culturally informed interventions addressing breast cancer survivorship exist, none have been developed or tested for Native Hawaiian, CHamoru, and Filipino women. To address this, the TANICA study began with key informant interviews in 2021.

METHODS

Purposive sampling and grounded theory approaches were used to conduct semi-structured interviews with individuals experienced in providing healthcare or implementing community programs and/or research with ethnic groups of interest in Guam and Hawai'i. A literature review and expert consultation identified intervention components, engagement strategies, and settings. Interview questions aimed to understand the relevance of evidence-based interventions and explored socio-cultural factors. Participants completed demographics and cultural affiliation surveys. Interviews were independently analyzed by trained researchers. Themes were mutually agreed upon by reviewers and key themes were identified based on frequencies.

RESULTS

Nineteen interviews were conducted in Hawai'i (n=9) and Guam (n=10). Interviews confirmed the relevance of most of the previously identified evidence-based intervention components for Native Hawaiian, CHamoru, and Filipino breast cancer survivors. Ideas around culturally responsive intervention components and strategies emerged that were shared across and unique to each ethnic group and site.

CONCLUSION

Evidence-based intervention components appear relevant, yet cultural and place-based strategies are needed for Native Hawaiian, CHamoru, and Filipino women in Guam and Hawai'i. Future research should triangulate these findings with the lived experiences of Native Hawaiian, CHamoru, and Filipino breast cancer survivors to develop culturally informed interventions.

Neighborhood level facilitators and barriers to hypertension management: A Native Hawaiian perspective

Native Hawaiians have a disproportionately high prevalence of hypertension, which is an important and modifiable risk factor for cardiovascular disease (CVD). To reduce CVD among Native Hawaiians, we must better understand facilitators and barriers to hypertension management (i.e., diet, physical activity, stress reduction) unique to Native Hawaiians. Despite evidence of neighborhood-level facilitators and barriers to hypertension management in other populations, there is limited research in Native Hawaiians. Participants from a randomized controlled trial (n = 40) were recruited for 5 focus groups. All participants were self-reported Native Hawaiians and had uncontrolled hypertension. Discussions elicited experiences and perceptions of neighborhood-level stressors as they relate to participants' hypertension management efforts. Audio recordings were transcribed and analyzed using ATLAS.ti for emergent themes. Five themes were identified: neighborhood description, community resources, neighborhood change, safety, and social connectedness. Novel barriers to hypertension control included loss of culture and loss of respect for elders, change in community feel, and over-development. Facilitators included social cohesion and collective power. These data provide a deeper understanding of how Native Hawaiians experience neighborhood factors and how those factors impact their efforts to improve their diets, physical activity, and stress management. The findings help to inform the development of multilevel CVD prevention programs. Further research is needed to explore the subtheme of social and emotional stress related to neighborhood change and CVD health risk due to cultural and historic trauma references.

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.

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.

Addressing Native Hawaiian and Pacific Islander Data Deficiencies Through a Community-based Collaborative Response to the COVID-19 Pandemic

Early evidence of disproportionate COVID-19 infection and death rates in Native Hawaiian and Pacific Islander communities in the continental US raised concerns for similar disparities in Hawai'i, where these communities make up 25% of the state's population. Representatives from more than 40 different government, academic, institutional and community-based organizations partnered to form the Hawai'i Native Hawaiian and Pacific Islander COVID-19 Response, Recovery, and Resilience Team. The team consists of 5 committees including the Data & Research Committee. This committee is tasked with examining issues regarding the acquisition, quality, public reporting, and utilization of race/ethnicity-related health data used to inform priorities and guide resource allocation. Problems addressed by this committee include: inconsistency across agencies in the use of race identifiers, defaulting to the Office of Management and Budget standards which aggregated Native Hawaiian and Pacific Islanders, and methods of data collection and reporting by the Department of Health. Outcomes include: 2 forms with race categories that reflect the population of Hawai'i; the reporting of disaggregated data by the Department of Health; and conversations with testing sites, laboratories, and health institutions urging a standardized form for race/ethnicity data collection. The collection and reporting of disaggregated race/ethnicity data is critical to guiding organizations in addressing underlying inequities in chronic disease and social determinants of health that can exacerbate the adverse effects of COVID-19. The Data and Research Committee's network offers a community-based model for collaborative work that honors culture and ensures Native Hawaiian, Pacific Islander, and other minority populations are recognized and counted.

Cultural dance significantly improves hypertension management

Hypertension (HT), uncontrolled blood pressure (>140/90 mmHg), is the leading preventable cause of premature death globally and a major risk factor for coronary heart disease, stroke, and other conditions. European and African regions have the highest prevalence rates at about 40% of adults. The U.S. has comparable rates and disturbing disparities in non-White minority groups. Native Hawaiians (NH), an indigenous U.S. population, are 70% more likely to have HT; 4 times more likely to have coronary heart disease or stroke than Whites. Hula, the cultural dance of NH, offers promise of a culturally responsive strategy for HT control.

We conducted a randomized clinical trial with a waitlist control to test the impact of a hula-based cultural dance intervention (CDI) on systolic blood pressure (SBP) in 263 NH with HT. All participants received HT education (e.g. diet, exercise, medication) during 3 1-hr sessions over 2 weeks, then randomly assigned to CDI (n = 131) or waitlist control (WC; n = 132). The CDI received 6 months of hula (2 1-hr sessions/week x 3 months, then 1 lesson/mth x 3 months with self-directed practice), with group activities to reinforce HT education. WC only received the initial HT education, then offered hula after the study. Assessments were done at 0-, 3- and 6-month, with 12-month for CDI only.

Baseline characteristics were balanced between groups, except for weight. Adjusting for weight and baseline SBP in intent-to-treat analysis, CDI achieved significant reductions (p < .05) in SBP (-15.3 mmHg; SE = 1.6) compared to WC (-11.8 mmHg, SE = 1.7). From 6 to 12 months, CDI maintained their SBP (mean change: 1.47 mmHg, SE = 1.26; p = .16) improvements at 12 months. CDI were more likely to achieve SBP reduction ≥ 10 mmHg than WC, 60% vs 48% (p = .03), respectively.

A CDI based on the NH cultural dance significantly improved HTN management in NH with uncontrolled SBP. Improvements were comparable to the best proven non-medication treatment of HT.

Key messages

Improving elevated blood pressure control with at-risk populations can be effectively and innovatively achieved by utilizing culturally responsive strategies, such as cultural dance interventions. Leveraging and aligning community strengths and health objectives leads to innovation and empowerment.

A Resilience Model of Adult Native Hawaiian Health Utilizing a Newly Multi-Dimensional Scale

Resilience has conventionally focused on an individual's ability to overcome adversity. Recent research expands on this definition, making resilience a multi-dimensional construct. Native Hawaiians experience health disparities compared to the general population of Hawai'i. Despite the pressing need to address health disparities, minimal research examines resilience factors that serve as buffers for adverse experiences of Native Hawaiians. The purpose of this study was to estimate psychometric properties of scales that measured resilience-based factors through multiple levels using higher-order confirmatory factor analyses (CFA) and ascertain if this construct of resilience mediated or moderated adversity experienced by a sample of Native Hawaiians. Participants included 125 adults who participated in the Hawaiian Homestead Health Survey. Based on higher-order CFA, resilience comprised internal assets measured by hope, satisfaction with life, and environmental mastery, and external resources measured by social support and Native Hawaiian cultural identity. Results of the structural equation models were consistent with literature focusing on resiliency and health. Findings emphasized the importance of enhancing resilience by considering strengths and resources on the individual, interpersonal, and community levels. Findings also demonstrated the need to address adversity factors directly, with a specific need of addressing socio-economic status factors. According to structural equation models, resilience slightly mediated and moderated the effect of adversity related to socio-economic status. These findings have implications for future research exploring resilience as a mediator or moderator of adversity among Native Hawaiians and emphasize a multi-faceted construct of resilience to promote better health outcomes.

How stakeholder engagement influenced a randomized comparative effectiveness trial testing two Diabetes Prevention Program interventions in a Marshallese Pacific Islander Community

BACKGROUND

Marshallese face significant health disparities, with particularly high rates of type 2 diabetes. Engaging stakeholders in the research process is essential to reduce health inequities.

METHODS

A community- and patient-engaged research approach was used to involve community Marshallese stakeholders in a randomized comparative effectiveness trial testing two Diabetes Prevention Program interventions.

RESULTS

The article outlines the engagement process and the specific influence that stakeholders had on the research planning and implementation, discussing the areas of agreement and disagreement between community and patient stakeholders and academic investigators and documenting changes to the research protocol.

CONCLUSION

The article provides an example of methods that can be used to design and conduct a randomized controlled trial testing with a population who has been underrepresented in research and suffered significant historical trauma.

An Examination of the Relationship between Discrimination, Depression, and Hypertension in Native Hawaiians

Native Hawaiians bear a disproportionate burden of hypertension. Discrimination and depression are potential hypertension risk factors. Although the relationship between discrimination and depression is well established, how these factors affect hypertension risk in indigenous populations remains unknown. We examined the relationship between discrimination, depression, and hypertension in adult Native Hawaiians. We hypothesized that greater frequency of perceived discrimination and greater frequency of depressive symptoms would independently increase the likelihood of having hypertension. Surveys were mailed to 540 adult Native Hawaiians residing on five Hawaiian Homesteads. The surveys measured: hypertension status, sociodemographic factors (age, gender, income, employment status), body mass index (BMI), physical activity frequency, smoking, Hawaiian cultural affiliation, American cultural affiliation, perceived discrimination, and depressive symptoms. Respondents (n=171) were mostly female (71%), a mean age of 57yrs, and 54% reported having hypertension. The logistic regression model included perceived discrimination, depression, BMI, frequency of vigorous physical activity, and Hawaiian cultural affiliation, and sociodemographic variables. The model showed that Hawaiian cultural affiliation and discrimination were significantly related to hypertension status. Depression was not related to hypertension status. Interaction analysis found that for individuals with lower Hawaiian cultural affiliation, frequent perceived discrimination was significantly associated with lower odds of having hypertension. The negative association between perceived discrimination and hypertension status was opposite from hypothesized. However, the interaction suggests this relationship holds only for less culturally affiliated individuals. These results underscore the varied nature of hypertension determinants and may have clinical implications for the treatment of hypertension in Native Hawaiians.

Culturally responsive approaches to health promotion for Native Hawaiians and Pacific Islanders

CONTEXT

Obesity, diabetes and cardiovascular disease (CVD) have reached epidemic proportions among Native Hawaiians/Pacific Islanders (NHPI). Culturally responsive interventions that account for their interpersonal, sociocultural and socioeconomic realities are a public health priority.

OBJECTIVE

To describe cultural adaptation and culturally grounded approaches to developing health interventions for NHPI and to review the culturally responsive approaches used by, and outcomes from, two long-standing community-based participatory research projects (CBPR) in Hawai'i: PILI 'Ohana and KāHOLO Projects.

METHODS

A literature review of 14 studies from these two projects was done to exemplify the methods applied to culturally adapting existing evidence-based interventions and to developing novel interventions from the 'ground up' to address health disparities in NHPI. Of the 14 studies reviewed, 11 were studies of the clinical and behavioural outcomes of both types of interventions.

RESULTS

Both culturally adapted and culturally grounded approaches using community-based assets and NHPI cultural values/practices led to establishing sustainable and scalable interventions that significantly improved clinical measures of obesity, diabetes and hypertension.

CONCLUSION

Several recommendations are provided based on the lessons learned from the PILI 'Ohana and KāHOLO Projects. Multidisciplinary and transdisciplinary research using CBPR approaches are needed to elucidate how human biology is impacted by societal, environmental and psychological factors that increase the risk for cardiometabolic diseases among NHPI to develop more effective health promotion interventions and public health policies.

Design of a comparative effectiveness randomized controlled trial testing a faith-based Diabetes Prevention Program (WORD DPP) vs. a Pacific culturally adapted Diabetes Prevention Program (PILI DPP) for Marshallese in the United States

BACKGROUND

Pacific Islander populations, including Marshallese, face a disproportionately high burden of health disparities relative to the general population.

OBJECTIVES

A community-based participatory research (CBPR) approach was utilized to engage Marshallese participants in a comparative effectiveness trial testing 2 Diabetes Prevention Program (DPP) interventions designed to reduce participant's weight, lower HbA1c, encourage healthy eating, and increase physical activity.

DESIGN

To compare the effectiveness of the faith-based (WORD) DPP to the culturally adapted (Pacific Culturally Adapted Diabetes Prevention Program [PILI]) DPP, a clustered randomized controlled trial (RCT) with 384 Marshallese participants will be implemented in 32 churches located in Arkansas, Kansas, Missouri, and Oklahoma. Churches will be randomly assigned to WORD DPP arm or to PILI DPP arm.

METHODS

WORD DPP focuses on connecting faith and health to attain a healthy weight, eat healthy, and be more physically active. In contrast, PILI DPP is a family and community focused DPP curriculum specifically adapted for implementation in Pacific Islander communities. PILI focuses on engaging social support networks to maintain a healthy weight, eat healthy, and be more physically active. All participants are assessed at baseline, immediate post intervention, and 12 months post intervention.

SUMMARY

Both interventions aim to cause weight loss through improving physical activity and healthy eating, with the goal of preventing the development of T2D. The clustered RCT will determine which intervention is most effective with the Marshallese population. The utilization of a CBPR approach that involves local stakeholders and engages faith-based institutions in Marshallese communities will increase the potential for success and sustainability. This study is registered at clinicaltrials.gov (NCT03270436).

Social Support Groups in the Maintenance of Glycemic Control after Community-Based Intervention

Native Hawaiians and other Pacific Islanders (NH/PI; e.g., Samoan and Chuukese) have higher type 2 diabetes prevalence compared to other groups in Hawai'i. Partners in Care (PIC), a culturally tailored, community-based, diabetes self-management education intervention (DSME), is effective at improving participants' glycemic control and self-care behaviors. Maintenance of improvements is challenging. Diabetes-related social support groups (SSG) are a promising maintenance component for DSME. This study examined the effects of a diabetes-specific SSG component relative to a control group, after the receipt of the 3-month PIC intervention, which was delivered to 47 adult NH/PI with type 2 diabetes. Participants were then randomized to either a 3-month, 6-session SSG or a control group. Hemoglobin A1c (HbA1c), blood pressure, triglycerides, cholesterol, and diabetes self-management knowledge and behaviors were assessed at baseline, 3 months, and 6 months. Results indicated significant improvements in HbA1c, diabetes-related self-management knowledge, and behaviors from baseline to 3-month assessment. However, no differences between the SSG and control group from 3-month to 6-month assessment suggest that all participants were able to maintain initial improvements. The SSG group had a significant decrease in systolic blood pressure from 3-month to 6-month assessment while the control group did not. Study limitations and future directions are discussed.

Translating the Diabetes Prevention Program in Native Hawaiian and Pacific Islander communities: the PILI 'Ohana Project

Native Hawaiians/Pacific Islanders experience a high prevalence of overweight/obesity. The Diabetes Prevention Program Lifestyle Intervention (DPP-LI) was translated into a 3-month community-based intervention to benefit these populations. The weight loss and other clinical and behavioral outcomes of the translated DPP-LI and the socio-demographic, behavioral, and biological factors associated with the weight loss were examined. A total of 239 Native Hawaiian/Pacific Islander adults completed the translated DPP-LI through four community-based organizations (CBOs). Changes from pre- to post-intervention assessments in weight, blood pressure, physical functioning, exercise frequency, and fat in diet were measured. Significant improvements on all variables were found, with differences observed across the four CBOs. CBOs with predominately Native Hawaiian and ethnically homogenous intervention groups had greater weight loss. General linear modeling indicated that larger baseline weight and CBO predicted weight loss. The translated DPP-LI can be effective for Native Hawaiians/Pacific Islanders, especially when socio-cultural, socio-economic, and CBO-related contextual factors are taken into account.

Metabolic equivalent determination in the cultural dance of hula

Ethnic minorities share an unequal burden of cardiometabolic syndrome. Physical activity (PA) has been shown to be an important factor for improving the outcomes of these diseases. While metabolic equivalents (METs) have been calculated for diverse activities, most cultural activities have not been evaluated. Hula, the traditional dance of Native Hawaiians, is practiced by men and women of all ages but its MET value is unknown. To our knowledge, this is the first scientific evaluation of energy expenditure of hula. 19 competitive hula dancers performed 2 dance sets of low- and high-intensity hula. METs were measured with a portable indirect calorimetry device. Mean and standard deviations were calculated for all the variables. A 2-way ANOVA was conducted to identify differences for gender and intensity. The mean MET were 5.7 (range 3.17-9.77) and 7.55 (range 4.43-12.0) for low-intensity and high-intensity, respectively. There was a significant difference between intensities and no significant difference between genders. This study demonstrates that the energy expenditure of both low- and high-intensity hula met the recommended guidelines for moderate and vigorous intensity exercise, respectively, and that hula can be utilized as a prescribed PA.

Depressive symptoms and cigarette smoking among Native Hawaiians

The present study estimated the prevalence of depressive symptoms and cigarette smoking and examined the relationship between depressive symptoms and cigarette smoking among native Hawaiians. Cross-sectional data from 524 rural, native Hawaiian from the Native Hawaiian Health Research Project are presented. Depressive symptoms were measured using the self-report Centre for Epidemiological Studies--Depression Scale. Information on smoking behavior and sociodemographic variables was collected. The prevalence of depressive symptoms was 15%, and significantly higher among participants with lower educational attainment. The prevalence of current smokers was 32%, and significantly higher among younger adults and participants with lower educational attainment. Regression analyses reported a significant relationship between CES-D scores and smoking status as well as between CES-D scores and number of cigarettes smoked daily. However, when education and age were included in the regression models, the relationships were attenuated. The findings and implications of this study are discussed.

Relationship between depressive symptoms and diabetes among native Hawaiians

Increased prevalence of depression has been reported among diabetes patients. We examined this association between diabetes and depressive symptoms in a population-based study where glucose tolerance status was determined with World Health Organization (WHO) criteria. Fasting plasma glucose (FPG) was determined from blood collected from 574 native Hawaiians. The Centers for Epidemiological Studies-Depression (CES-D) scale was used to assess depressive symptoms in association with diabetes history and hemoglobin A1c (HbA1c). A significant association was observed between depressive symptoms and HBA1c that persisted after adjusting for age, BMI, gender, education, and after exclusion of participants reporting a history of diabetes. Diabetes history was no longer associated with CES-D depressive symptoms after adjusting for HbA1c. These results support the hypothesis that depressive symptoms associated with diabetes may be partially explained by a shared neuroendocrinological disturbance.
