Pancreatic cancer among Pacific Islanders: a comprehensive analysis of an understudied racial group

OBJECTIVE

Racial disparities in care and outcome have been demonstrated for several cancers, but it is not clear that a similar discrepancy exists for pancreatic cancer. Furthermore, there are limited data describing the pancreatic cancer experience of Pacific Islanders. The primary objective of this study was to analyze the clinical characteristics, treatment, and outcomes of Pacific Islander patients with pancreatic cancer.

DESIGN

We obtained data for a consecutive sample of pancreatic adenocarcinoma patients who presented to the largest hospital in Hawaii from 1 January 2000, through 31 December 2019. Analyses were performed for the entire population and separately for patients who had their cancer resected. Overall survival was calculated by the Kaplan-Meier method. Cox proportional hazards regression models were constructed to determine the prognostic capacity of clinical and pathologic factors.

RESULTS

A total of 1040 patients were included in the final analysis. Pacific islanders presented at a significantly younger age compared to Whites or Asians and had the highest Medicaid rate. There were no statistically significant racial differences in stage at presentation or treatments. We did not demonstrate an association between race and survival on univariate analysis, nor after adjusting for demographic and tumor factors. Age, stage, and treatment were significantly associated with survival for both univariate and multivariate analyses.

CONCLUSION

We did not demonstrate disparate outcomes among Pacific Islanders with pancreatic cancer. This is likely due in part to the absence of a screening test and the notable poor prognosis of pancreatic adenocarcinoma. Furthermore, equity in treatment may have contributed to racial parity in survival.

A Report on the Ke Ola O Ka 'Āina: 'Āina Connectedness Scale

Optimal health from a Native Hawaiian worldview is achieved by being pono (righteous) and maintaining lōkahi (balance) with all our relations, including our relationships as Kānaka (humankind) with 'Āina (land, nature, environment, that which feeds) and Akua (spiritual realm). The purpose of this study is to explore the role of 'Āina connectedness in Native Hawaiian health and resilience to inform the development of the 'Āina Connectedness Scale. Qualitative methods were conducted with 40 Native Hawaiian adults throughout Hawai'i. Three themes emerged: (1) 'Āina is everything; (2) Connection to 'Āina is imperative to health; and (3) Intergenerational health, healing, and resilience are reflected through intergenerational connectedness with 'Āina. Qualitative findings, supplemented with a scoping review of land, nature, and cultural connectedness scales, led to the development of the 'Āina Connectedness Scale, which examined the degree to which people feel connected to 'Āina, with implications for future research. 'Āina connectedness may address concerns related to health disparities that stem from colonization, historical trauma, and environmental changes and better our understanding of Native Hawaiian health by fostering stronger ties to land. Resilience- and 'Āina-based approaches are critically important to health equity and interventions that aim to improve Native Hawaiian health.

Social Networks, Health Information Sharing, and Pandemic Perceptions among Young Adults in Hawai'i during the COVID-19 Pandemic

Limited information exists about social network variation and health information sharing during COVID-19, especially for Native Hawaiians (NH), Other Pacific Islanders (OPI), and Filipinos, who experienced COVID-19 inequities. Hawai'i residents aged 18-35 completed an online survey regarding social media sources of COVID-19 information and social network health information measured by how many people participants: (1) talked to and (2) listened to about health. Regression models were fit with age, gender, race/ethnicity, chronic disease status, pandemic perceptions, and health literacy as predictors of information sources (logistic) and social network size (Poisson). Respondents were 68% female; 41% NH, OPI, or Filipino; and 73% conducted a recent COVID-19 digital search for themselves or others. Respondents listened to others or discussed their own health with ~2-3 people. Respondents who talked with more people about their health were more likely to have larger networks for listening to others. In regression models, those who perceived greater risk of acquiring COVID-19 discussed their health with more people; in discussing others' health, women and those with chronic diseases listened to a greater number. Understanding young adults' social networks and information sources is important for health literacy and designing effective health communications, especially to reach populations experiencing health inequities.

A Qualitative Study on the Motivators, Barriers and Supports to Participation in a Pediatric Produce Prescription Program in Hawai'i

Produce prescriptions that provide vouchers to individuals to purchase fresh FVs at a specified retail outlet have the potential to positively impact food security status, diet, and chronic disease risk. However, maximizing program participation is vital to ensuring program success. This research describes motivators, barriers, and support for participation in a child produce prescription program among a population of Native Hawaiian and Other Pacific Islanders, who are underrepresented in this field of research. This qualitative grounded theory study was nestled within a quasi-experimental pilot intervention trial and included semi-structured interviews with pediatric program participants. Twenty-five interviews were conducted, which represented one-third of program participants. The top support factors for program participation included: ease of voucher use, program convenience, health center/pediatrician endorsement and positive communications with farmers' market vendors. Key motivators for program participation were produce enjoyment, child support, financial support, and positive impacts on family. Three themes emerged consistently as barriers to participation amongst participants, (1) difficult use of vouchers, (2) conflicting schedules, and (3) online market concerns. (4) Conclusions: This research offers insight into policy implications as the number of produce prescription programs has grown. These findings suggest that key program design characteristics can enhance and support program participation.

Reclaiming 'Āina Health in Waimānalo

Kānaka Maoli (Native Hawaiian) worldviews of health emphasize pono (righteousness) and lōkahi (balance), which extends to include relationships with other people, akua (spiritual realm), and 'āina (land). The purpose of this qualitative study was to explore the role of 'āina and 'āina connection in health and resilience based on the perspectives of 12 Kānaka Maoli adults from the Waimānalo community. Three major themes were identified: 'Āina is everything, 'āina is health, and community healing through community-led initiatives. A better understanding of 'āina connection is important to improve our knowledge of Hawaiian health. A connection to 'āina may specifically address health concerns resulting from historical trauma and environmental changes.

Prepregnant Obesity of Mothers in a Multiethnic Cohort Is Associated with Cord Blood Metabolomic Changes in Offspring

Maternal obesity has become a growing global health concern that may predispose the offspring to medical conditions later in life. However, the metabolic link between maternal prepregnant obesity and healthy offspring has not yet been fully elucidated. In this study, we conducted a case-control study using a coupled untargeted and targeted metabolomic approach from the newborn cord blood metabolomes associated with a matched maternal prepregnant obesity cohort of 28 cases and 29 controls. The subjects were recruited from multiethnic populations in Hawaii, including rarely reported Native Hawaiian and other Pacific Islanders (NHPI). We found that maternal obesity was the most important factor contributing to differences in cord blood metabolomics. Using an elastic net regularization-based logistic regression model, we identified 29 metabolites as potential early-life biomarkers manifesting intrauterine effect of maternal obesity, with accuracy as high as 0.947 after adjusting for clinical confounding (maternal and paternal age, ethnicity, parity, and gravidity). We validated the model results in a subsequent set of samples (N = 30) with an accuracy of 0.822. Among the metabolites, six metabolites (galactonic acid, butenylcarnitine, 2-hydroxy-3-methylbutyric acid, phosphatidylcholine diacyl C40:3, 1,5-anhydrosorbitol, and phosphatidylcholine acyl-alkyl 40:3) were individually and significantly different between the maternal obese and normal-weight groups. Interestingly, hydroxy-3-methylbutyric acid showed significantly higher levels in cord blood from the NHPI group compared to that from Asian and Caucasian groups. In summary, significant associations were observed between maternal prepregnant obesity and offspring metabolomic alternation at birth, revealing the intergenerational impact of maternal obesity.

Mālama nā makua i nā keiki me ka hānō: Native Hawaiian Parents Caring for Their Children with Asthma (Part 2)

Objective: Native Hawaiian children have the highest prevalence of asthma among all ethnicities in Hawai'i. Mālama Part 2 describes continuing research, exploring contemporary native Hawaiian parents' perspective, and experience of caring for their children with asthma in the context of uncertainty while living on the islands of Hawai'i, Kaua'i, Maui, Moloka'i and Lāna'i. Design: Descriptive qualitative approach by means of directed content analysis using focus groups was applied to this study. Eight open-ended questions elicited asthma history, asthma management, and how the Hawaiian culture affects parents' health practices. Directed content analysis applied Mishel's Uncertainty in Illness Theory (UIT) to guide data collection, organization, and analysis. Sample: Thirty-three native Hawaiian parents with a child with asthma met in 9 separate focus groups during 2012-2015 on the islands of Hawai'i, Kaua'i, Maui, Moloka'i, and Lāna'i. Results: The study's findings were congruent with the first Mālama study results of focus groups on O'ahu. Contextual influences including indigenous worldview, cultural values, history, and assimilation and acculturation factors affected native Hawaiian parents' perceptions and experiences with conventional asthma care. Moreover, Hawaiian parents living on islands outside of metropolitan O'ahu reported geographic barriers that contributed to their uncertainty. Conclusion: Political action is required for comprehensive medical care, health education, and nursing services to be delivered to families living on all islands. Integrating Hawaiian cultural values, involving 'ohana, and applying complementary alternative therapies as well as standard asthma management will strongly support native Hawaiian parents caring for their children with asthma.

Adapting a Sexually Transmitted Infection Prevention Intervention Among Female Adolescents in Hawai'i

Epidemiological data suggest that Native Hawaiian, Pacific Islander, and Asian American (NHPIA) adolescent females in Hawai'i are at elevated risk for sexually transmitted infections (STIs). These data also indicate that teen girls in Hawai'i are more likely to engage in high-risk sexual behaviors than boys. Despite this compelling evidence, there is a paucity of published research on effective STI prevention protocols that target NHPIA female adolescents. In light of this need, the purpose of this study was to adapt an evidence-based, group-level STI behavioral prevention intervention targeting local NHPIA adolescent girls in Hawai'i for implementation by community-based organizations (CBOs). This article describes the adaptation of an evidence-based STI prevention intervention in partnership with a CBO, using a locally modified ADAPT-ITT model as a basis for the adaptation process. This research consisted of two phases: (1) development of an initial test version of an adapted intervention and (2) the development of the final version of the adapted intervention, Girl Power Hawai'i. The results provide the empirical and foundational research necessary for a tailored intervention that can be readily implemented by CBOs for local teen girls in Hawai'i.
