Culturally adapting an evidence-based intervention to promote a healthy diet and lifestyle for Yup'ik Alaska native communities.

Underserved populations are at increased risk for obesity and related cardiovascular disease, type 2 diabetes, and other chronic diseases. Lack of access to healthy foods, sedentary behaviour, and other social environmental factors contribute to disease risk. Yup'ik Alaska Native communities are experiencing lifestyle changes that are likely to affect their cardiometabolic risks. Barrera & Castro's Cultural Adaptation Framework was used to adapt an evidence-based intervention (EBI) originally designed for Latino communities for use in Yup'ik communities. Focus groups and key informant interviews were held in two Yup'ik communities. Major themes included causes of obesity, barriers and facilitators to healthy foods and physical activity, and intervention ideas. The adaptation process was guided by a Community Planning Group of Yup'ik women and included information gathering, preliminary adaptation design, preliminary adaptation tests, and adaptation refinement. Two of the adapted educational modules were pilot tested. Involving community members as co-researchers in cultural adaptation is vital for an EBI to be effective in another population. Small group gatherings led by local lay health workers are culturally appropriate and may be an effective health promotion model in Yup'ik communities. Social environmental factors affecting healthy food availability and physical activity need further exploration.

Provider and community perspectives of dental therapists in Alaska's Yukon-Kuskokwim Delta: A qualitative programme evaluation.

OBJECTIVES: Dental therapists deliver preventive and basic restorative care and have been practicing since 2006 in Alaska's Yukon-Kuskokwim (YK) Delta. In this qualitative programme evaluation, we documented health providers' and community members' experiences with dental therapy. The goal of the evaluation was to develop a conceptual model of dental care delivery in Alaska Native Communities centred on dental therapists. METHODS: We developed semi-structured interview scripts and used snowball sampling to recruit 16 health providers with experience providing care in the YK Delta and 125 community members from six YK Delta Communities in 2017 and 2018. The six communities were a stratified convenience sample based on community-level exposure to dental therapists (high, medium and no exposure). Interview data were digitally recorded, transcribed, verified for accuracy and coded inductively into conceptual domains using content analytic methods. RESULTS: Providers believed individuals living in the YK Delta have benefited from clinic-based restorative care and community-based education provided by dental therapists. The restricted scope of dental therapy practice limits the complexity of care that may be offered to patients. However, community members expressed high satisfaction with the quality of care provided by dental therapists. Community members noted more widespread knowledge and evolving norms about oral health and believed dental therapists are helping to prevent disease and improve quality of life. Participants believed access to dental care for children has improved over the years, but felt that many adults in the YK Delta continue to have unmet needs. A potential barrier to sustained programme effectiveness is low retention of dental therapists in the region, driven primarily by reports that dental therapists feel overworked, stressed and geographically isolated. CONCLUSIONS: Dental therapists have contributed to the dental care delivery system in Alaska's YK Delta. Future opportunities remain within the system to address the needs of adults, develop strategies to retain dental therapists in the region and incorporate evidence-based, prevention-oriented strategies to improve oral health behaviours and reduce oral diseases.

Alaska Native Children Do Not Prefer Sugar-Sweetened Fruit Drinks to Sugar-Free Fruit Drinks.

BACKGROUND: Alaska Native children, including children of Yup'ik descent, consume large volumes of sugar-sweetened fruit drinks, which contain added sugars that contribute to obesity, diabetes, and dental caries. To date, taste preference evaluations have not been conducted on commercially available sugar-free fruit drinks. OBJECTIVE: The study tested the hypothesis that children would have equal preference for sugar-free and sugar-sweetened fruit drinks. DESIGN: This was an experimental two-alternative forced-choice paired preference test. PARTICIPANTS/SETTING: The study focused on a convenience sample of Yup'ik children, aged 7 to 10 years, recruited and enrolled from the Yukon-Kuskokwim Health Corporation dental clinic in Bethel, AK (N=89). INTERVENTION: Children evaluated four different commercially available sugar-free fruit drinks paired with the sugar-sweetened versions of each flavor. Order of flavor pair presentation was alternated across children, and order of presentation within each of the four pairs was randomized across pairs. MAIN OUTCOME MEASURES: The outcome was taste preference for the sugar-free versus the sugar-sweetened version of a fruit drink. STATISTICAL ANALYSES PERFORMED: A test of equivalence was run across all four flavors and separately for each flavor using two one-sided tests. RESULTS: The data failed to demonstrate equivalence of the sugar-free and sugar-sweetened fruit drinks across all four flavors (P=0.51) or separately for each flavor. However, this was not because of a preference for sugar-sweetened drinks. The preference for sugar-free drinks overall and for each flavor was >50%. Although the lower bounds of the 90% CIs were within the range of equivalence (40% to 60%), the upper bounds were outside the range of equivalence (>60%). According to post hoc analyses, similar preferences were observed for Yup'ik and non-Yup'ik children, boys and girls, and children of different ages. CONCLUSIONS: Taste preference findings suggest that sugar-free fruit drinks may be a well-tolerated alternative to sugar-sweetened fruit drinks for Yup'ik children in Alaska Native communities.

Cultural values, coping, and hope in Yup'ik communities facing rapid cultural change.

Historical trauma and rapid cultural change contribute to a high burden of stress in Alaska Native communities. The goal of the Yup'ik Experiences of Stress and Coping Project was to better understand stress and coping in Yup'ik communities and the role of cultural values and practices in coping. Sixty Yup'ik adults aged 18-84 years took part in semistructured interviews. They discussed how they coped with salient stressful experiences and shared the things that bought them hope and peace. Interview themes were identified and inter-relationships between themes were explored through social network analysis. Participants discussed the importance of cultural traditions in coping, including subsistence, dancing and drumming, intergenerational transmission of knowledge, and reflective awareness of interconnections with others. Participants found strength in family relationships, spirituality, helping others, and coming together as a community. Three coping clusters emerged: Ilaliurucaraq (be welcoming) involved opening one's frame of mind and building connections; Yuuyaraq (Yup'ik way of life) focused on Yup'ik traditions and values; and Assircaarturluni Yuuyaraq (try to live a better life) involved healing from historical trauma. Findings illustrate the resilience and evolving strengths of rural Yup'ik communities facing a continually changing cultural landscape and provide information for developing community-driven culturally based interventions.

Association between added sugar intake and dental caries in Yup'ik children using a novel hair biomarker.

BACKGROUND: Dental caries (tooth decay) is a significant public health problem in Alaska Native children. Dietary added sugars are considered one of the main risk factors. In this cross-sectional pilot study, we used a validated hair-based biomarker to measure added sugar intake in Alaska Native Yup'ik children ages 6-17 years (N = 51). We hypothesized that added sugar intake would be positively associated with tooth decay. METHODS: A 66-item parent survey was administered, a hair sample was collected from each child, and a dental exam was conducted. Added sugar intake (grams/day) was measured from hair samples using a linear combination of carbon and nitrogen ratios. We used linear and log-linear regression models with robust standard errors to test our hypothesis that children with higher added sugar intake would have a higher proportion of carious tooth surfaces. RESULTS: The mean proportion of carious tooth surfaces was 30.8 % (standard deviation: 23.2 %). Hair biomarker-based added sugar intake was associated with absolute (6.4 %; 95 % CI: 1.2 %, 11.6 %; P = .02) and relative increases in the proportion of carious tooth surfaces (24.2 %; 95 % CI: 10.6 %, 39.4 %; P < .01). There were no associations between self-reported measures of sugar-sweetened food and beverage intake and tooth decay. CONCLUSIONS: Added sugar intake as assessed by hair biomarker was significantly and positively associated with tooth decay in our sample of Yup'ik children. Self-reported dietary measures were not associated tooth decay. Most added sugars were from sugar-sweetened fruit drinks consumed at home. Future dietary interventions aimed at improving the oral health of Alaska Native children should consider use of objective biomarkers to assess and measure changes in home-based added sugar intake, particularly sugar-sweetened fruit drinks.

Disseminating research in rural Yup'ik communities: challenges and ethical considerations in moving from discovery to intervention development.

BACKGROUND: The native people of Alaska have experienced historical trauma and rapid changes in culture and lifestyle patterns. As a consequence, these populations shoulder a disproportionately high burden of psychological stress. The Yup'ik Experiences of Stress and Coping project originated from rural Yup'ik communities' concerns about stress and its effects on health. It aimed to understand the stressful experiences that affect Yup'ik communities, to identify coping strategies used to deal with these stressors and to inform culturally responsive interventions. OBJECTIVES: Here, we examine the process of moving from research (gaining understanding) to disseminating project findings to translation into intervention priorities. We highlight the importance of community participation and discuss challenges encountered, strategies to address these challenges and ethical considerations for responsible intervention research with indigenous communities that reflect their unique historical and current socio-cultural realities. DESIGN: Community-wide presentations and discussions of research findings on stress and coping were followed by smaller Community Planning Group meetings. During these meetings, community members contextualized project findings and discussed implications for interventions. This process placed priority on community expertise in interpreting findings and translating results and community priorities into grant applications focused on intervention development and evaluation. RESULTS: Challenges included translation between English and Yup'ik, funding limitations and uncertainties, and the long timelines involved in moving from formative research to intervention in the face of urgent and evolving community needs. The lack of congruence between institutional and community worldviews in the intervention research enterprise highlights the need for "principled cultural sensitivity". CONCLUSIONS: Cultural sensitivity requires sharing results that have practical value, communicating openly, planning for sustainability and incorporating indigenous knowledge and expertise through a community-guided process. Our research findings will inform continued work within our partnership as we co-develop culturally based strategies for multilevel community interventions to address stress.

Value of Community Partnership for Understanding Stress and Coping in Rural Yup'ik Communities: The CANHR Study.

Stress and trauma can compromise physical and mental health. Rural Alaska Native communities have voiced concern about stressful and traumatic events and their effects on health. The goal of the Yup'ik Experiences of Stress and Coping Project is to develop an in-depth understanding of experiences of stress and ways of coping in Yup'ik communities. The long-range goal is to use project findings to develop and implement a community-informed and culturally grounded intervention to reduce stress and promote physical and mental health in rural Alaska Native communities. This paper introduces a long-standing partnership between the Yukon-Kuskokwim Regional Health Corporation, rural communities it serves, and the Center for Alaska Native Health Research at the University of Alaska Fairbanks. Within the context of the Stress and Coping project, we then discuss the value and challenges of taking a CBPR approach to advance science and address a priority community concern, and share strategies to respond to challenges. Focus groups were conducted to culturally adapt an existing structured interview and daily diary protocol to better fit Yup'ik ways of knowing. As modified, these interviews increased understanding of stress and coping particular to two Yup'ik communities. Challenges included the geographical nature of Yup'ik communities, communication barriers, competing priorities, and confidentiality issues. Community participation was central in the development of the study protocol, helped ensure that the research was culturally appropriate and relevant to the community, and facilitated access to participant knowledge and rich data to inform intervention development.

Disseminating research on community health and well-being: a collaboration between Alaska Native villages and the academe.

Collaboration between Alaska Native communities and the academe is very important. This project focused on disseminating research findings to communities in a manner that is culturally appropriate and useful in planning the communities' next steps. The project relied on a collaborative process, described in terms of the activities that transpired, the approaches taken, the challenges, the lessons learned, and some examples of the final disseminated material.

Stress, coping, and well-being among the Yup'ik of the Yukon-Kuskokwim Delta: the role of enculturation and acculturation.

OBJECTIVES: To report on the relationships between cultural identity and stress, coping, and psychological well-being in Yup'ik communities. STUDY DESIGN: A quantitative self-administered questionnaire. METHODS: A health and wellness survey was completed by a total of 488 Yup'ik participants (284 women and 204 men) from 6 rural villages in the Yukon-Kuskokwim Delta region. Respondents were fairly equally distributed across an age range of 14 to 94 (mean +/- SD = 38.50 +/- 17.18). RESULTS: Participants who reported living more of a Kass'aq way of life (greater acculturation) reported experiencing greater psychosocial stress, less happiness, and greater use of drugs and alcohol to cope with stress. Participants who reported identifying more with a traditional Yup'ik way of life reported greater happiness, more frequent use of religion and spirituality to cope with stress, and less frequent use of drugs and alcohol to cope with stress. CONCLUSIONS: In conjunction with previous research, the data strongly indicates that in general, Yup'ik people in the Y-K Delta tend to associate stress and negative health outcomes with the process of acculturation, and health and healing with the process of enculturation. Research that focuses on documenting the intrinsic strengths of indigenous worldviews may contribute to positive transformations in community health.
