The cost-efficacy of a healthy food box for managing hypertension within a native American population: a group randomized controlled trial.

BACKGROUND: Dietary interventions are used for the treatment of hypertension. We evaluated the cost-efficacy of delivering boxes of healthy, culturally tailored foods and checks that can only be spent on produce in a Native American population. METHODS: We conducted a group randomized controlled trial from 2018 to 2020 with N = 2 treatment counties and N = 2 control counties and a total of N = 160 Native American adults with baseline stage 1 or stage 2 hypertension. Participants in the intervention group received monthly boxes of food that adheres to the Dietary Approaches to Stop Hypertension diet as well as checks that could only be spent on produce for 6 months. We measured blood pressure and quality of life at baseline and at a 6-month follow-up in both intervention and control groups. We used ordered logistic regression to estimate the effect of treatment on probability of blood pressure improvements. We then conducted a cost-efficacy analysis. RESULTS: We found that treatment was effective in reducing blood pressure in women with stage 1 hypertension at baseline. Based on this finding, we also estimate that this intervention satisfies normative cost-effectiveness thresholds, even when lifetime treatment is needed to preserve the impact, so long as treatment is only continued in those who respond to treatment. CONCLUSIONS: Direct delivery of healthy foods and checks that can only be spent on produce are a potentially cost-effective intervention for the management of hypertension among Native American women with stage 1 hypertension. Further research is needed to understand why we found an impact only for this group.

The Worsening Problem of Food Insecurity.

This JAMA Forum discusses disparities and food insecurity among underserved populations in the US, the actions being taken by states, tribal actions, and additional steps to ensure food and nutrition security.

The Center for Indigenous Innovation and Health Equity: The Osage Nation's Mobile Market.

Over the last decade, the Osage Nation has actively worked to build Tribal food sovereignty within the reservation where rates of chronic disease and food insecurity are higher than the United States general population. In 2013, the Nation repurposed land toward the development of a Tribal farm with the aim of providing healthy foods to Osage citizens. Produce from the farm is distributed to elders groups, at Tribal Head Starts and schools, and to support the tribal food distribution program. These efforts have led to improved vegetable intake among Osage children, contributing to improved food security, but there is concern that tribal members who live in more remote areas of the Nation or have transportation or mobility issues are not able to access farm production. In partnership with the Center for Indigenous Health Equity (CIIHE), Osage Nation engaged in a community-based participatory research study to assess reservation areas with the greatest barriers to healthy foods and to identify community priorities for intervention. Guided by the principles of food sovereignty, which assert that intervention efforts must address the underlying structural issues of inequality, Osage has designed a mobile market initiative to expand the reach of the Harvest Land farm and deliver healthy, tribally produced meats, herbs, and fresh vegetables to areas with the highest rates of food insecurity. We describe the participatory research efforts and evaluation strategies that center Osage priorities for food security and food sovereignty.

The Choctaw Nation's Growing Hope Program.

The Choctaw Nation of Oklahoma's Historic Preservation Department (HPD) and the Center for Indigenous Health Equity (CIIHE) are partnering to implement and evaluate food sovereignty interventions to better understand the potential impact of such programs on individual and community health. The HPD's Growing Hope Program is a food sovereignty initiative that aims to restore traditional Choctaw gardens, which were once a physical, social, and cultural center of Choctaw life. The program combines heirloom seeds and the stories of their origins, gardening education and technical assistance, cooking classes, and a Choctaw youth internship program to support intergenerational knowledge and the restoration of culture and food security. Since its inception the program has provided Choctaw families with ancestral Choctaw cultivar seeds and provided the technical assistance to support the growing of sustainable, healthy, traditional Choctaw foods.

Food Sovereignty and Health: A Conceptual Framework to Advance Research and Practice.

Settler colonialism disrupted traditional Indigenous foodways and practices and created high rates of diet-related disease among Indigenous peoples. Food sovereignty, the rights of Indigenous peoples to determine their own food systems, is a culturally centered movement rooted in traditional Indigenous knowledge. This approach directly intervenes upon systems-level barriers to health, making it an important strategy for health equity. While food sovereignty initiatives can be found within many Indigenous communities, the conceptual linkages between food sovereignty and health have not been well documented within the public health literature. We present a practice-informed conceptual framework developed as part of the Center for Indigenous Innovation and Health Equity (CIIHE) initiative, a community-academic partnership with the goal of strengthening Indigenous food systems and practices to promote health and well-being. The framework emphasizes connectedness, including the transmission of knowledge across generations and the restoration of relational responsibilities, as central to Indigenous concepts of health and wellness.

Food Security and Food Sovereignty: The Difference Between Surviving and Thriving.

Previous research in American Indian and Alaska Native (AI/AN) communities has documented high prevalence of food insecurity. Yet many AI/AN scholars and communities have expressed concerns that the dominant societal conceptions of food security are not reflective of the teachings, priorities, and values of AI/AN communities. Food security initiatives often focus on access to food and, at times, nutrition but little consideration is given to cultural foods, the spirituality carried through foods, and whether the food was stewarded in a way that promotes well-being not just for humans but also for plants, animals, land, and water. Despite the concerns of AI/AN communities that their needs are not centered in dominant societal food conceptualizations and food security programming, the food sovereignty efforts of AI/AN communities have captured national attention as a solution to modern food system inequities. Indigenous Food Sovereignty (IFS) is a holistic approach to food that incorporates values of relationality, reciprocity, and relationships. Fundamental differences exist between food security and food sovereignty, yet dominant society often reduces IFS as a solution to food security, rather than an entirely different food system that is predicated on values that contrast with that of dominant society. Despite calls to decolonize the definition and measurement of food security, we explore whether fixing the concept of food security is a worthy endeavor or whether efforts would be better spent supporting the resurgence and revitalization of AI/AN food values, food knowledge, and community food sovereignty initiatives.

Supporting Traditional Foodways Knowledge and Practices in Alaska Native Communities: The Elders Mentoring Elders Camp.

The transmission of generational knowledge in Alaska Native communities has been disrupted by colonization and led to declining health among Alaska Natives, as evidenced by the loss of knowledge regarding traditional foods and foodways and increasing rates of cardiometabolic disorders impacting Alaska Natives. Elders play a central role in passing down this generational knowledge, but emerging Elders may have difficulty in stepping into their roles as Elders due to the rapid social and cultural changes impacting their communities. The Center for Alaska Native Health Research (CANHR) and the Denakkanaaga Elders Program are partnering with the Center for Indigenous Innovation and Health Equity to uplift and support traditional food knowledge and practices to promote health in Alaska Native communities. Guided by a decolonizing and Indigenizing framework, researchers at CANHR are working with Athabascan Elders in the Interior of Alaska to strengthen and protect the intergenerational transmission of cultural knowledge and practices for emerging Elders. This community-academic partnership will implement and evaluate an Elders Mentoring Elders Camp to focus on repairing and nurturing relationships through the practice and preservation of cultural knowledge and practices, including traditional foodways. This initiative contributes to the intergenerational transmission of knowledge, which is necessary to keep culture alive and thriving.

The Development of a Community-Led Alaska Native Traditional Foods Gathering.

Traditional foods and foodways are a critical part of health and well-being for Alaska Native/American Indian (ANAI) peoples. However, many of these foods are being replaced by ultra-processed foods high in fat, sugar, and sodium. The cultural knowledge needed to gather, hunt, and fish to acquire these foods is not being passed down to younger generations, due to lingering effects of colonialism, leading to poor health outcomes among ANAI peoples. Southcentral Foundation (SCF) and the Center for Indigenous and Health Equity (CIIHE) are using community-based participatory research to identify and prioritize food sovereignty interventions to strengthen the transmission of cultural knowledge across generations and improve ANAI health. Through the implementation of a comprehensive landscape analysis and the development of a community advisory board, SCF has planned an Alaska Native Traditional Foods Gathering to highlight regional efforts to document, revitalize, and share cultural food knowledge and practices to build healthy communities.

Framing an Indigenous Food Sovereignty Research Agenda.

Access to healthy and appealing food is essential for individuals to be able to live a healthy and quality life. For decades, food security has been a priority issue for public health professionals. Food sovereignty expands upon the concept of food insecurity (i.e., having access to nutritious and culturally relevant food) by incorporating people's rights to define their own food system. The expanded focus of food sovereignty on food systems prioritizes public health professionals' role in supporting environmental- and systems-level initiatives and evaluating their implications for health, economics, and the natural environment. Food sovereignty is of particular importance for Indigenous peoples (i.e., American Indian, Alaska Native, Native Hawaiian, and Pacific Islander communities). Colonization had demonstrable consequences, with many Indigenous communities being forcibly relocated from traditional lands, alongside the destruction of traditional food sources. Indigenous food sovereignty aligns with the sovereign nation status that American Indian tribes and Alaska Native communities have with the United States. Furthermore, the worldviews that incorporate Indigenous communities' relational responsibilities to care for their food systems, according to their traditional practices and beliefs (Coté, 2016; Morrison, 2011), uniquely positions Indigenous peoples to lead food sovereignty initiatives. In this article, we explore what is currently known regarding food sovereignty and health. We then discuss opportunities to expand the evidence on Indigenous food sovereignty's relationships with (1) health and well being, (2) economics, (3) the natural environment, and (4) programming facilitators and barriers.

Food Systems, Food Sovereignty, and Health: Conference Shares Linkages to Support Indigenous Community Health.

The Center for Indigenous Innovation and Health Equity (CIIHE) at Oklahoma State University Center for Health Sciences (OSU-CHS) is a community-academic partnership with Indigenous peoples from Alaska, Hawai'i, and Oklahoma. The CIIHE supports communities to strengthen traditional food practices and food sovereignty and evaluate the impact of those efforts on health. In February 2022, the CIIHE sponsored and hosted a virtual conference to better understand how food sovereignty initiatives can improve health. More than 600 participants gathered to hear the latest research and practice in the areas of public health and agriculture, nutrition, community-based and Indigenous knowledge, and health economics. Community-led food sovereignty initiatives being implemented as part of the CIIHE were featured along with other Indigenous initiatives in urban, rural, and reservation communities. A survey was administered to conference participants to assess food sovereignty topics and priorities for future research. In this Practice Note, we describe innovative community-led initiatives presented as part of the conference and recommendations for action emerging from qualitative and quantitative data collected from conference participants.

Native opportunities to stop hypertension: study protocol for a randomized controlled trial among urban American Indian and Alaska Native adults with hypertension.

Introduction: American Indian and Alaska Native (AI/AN) adults experience disproportionate cardiovascular disease (CVD) morbidity and mortality compared to other races, which may be partly attributable to higher burden of hypertension (HTN). Dietary Approaches to Stop Hypertension (DASH) is a high-impact therapeutic dietary intervention for primary and secondary prevention of CVD that can contribute to significant decreases in systolic blood pressure (BP). However, DASH-based interventions have not been tested with AI/AN adults, and unique social determinants of health warrant independent trials. This study will assess the effectiveness of a DASH-based intervention, called Native Opportunities to Stop Hypertension (NOSH), on systolic BP among AI/AN adults in three urban clinics. Methods: NOSH is a randomized controlled trial to test the effectiveness of an adapted DASH intervention compared to a control condition. Participants will be aged ≥18 years old, self-identify as AI/AN, have physician-diagnosed HTN, and have elevated systolic BP (≥ 130 mmHg). The intervention includes eight weekly, tailored telenutrition counseling sessions with a registered dietitian on DASH eating goals. Intervention participants will be provided $30 weekly and will be encouraged to purchase DASH-aligned foods. Participants in the control group will receive printed educational materials with general information about a low-sodium diet and eight weekly $30 grocery orders. All participants will complete assessments at baseline, after the 8-week intervention, and again 12 weeks post-baseline. A sub-sample of intervention participants will complete an extended support pilot study with assessments at 6- and 9-months post-baseline. The primary outcome is systolic BP. Secondary outcomes include modifiable CVD risk factors, heart disease and stroke risk scores, and dietary intake. Discussion: NOSH is among the first randomized controlled trials to test the impact of a diet-based intervention on HTN among urban AI/AN adults. If effective, NOSH has the potential to inform clinical strategies to reduce BP among AI/AN adults.

Changes in Meal and Menu Quality at Early Care and Education Programs after Training with Food Service Staff: the FRESH Study.

Background: Prevalence of obesity in Native American (NA) children is disproportionately high, indicating a higher risk of health disparities. Many children attend early care and education (ECE) programs, presenting an opportune environment to improve meal and menu quality as the intake of healthy foods is associated with lowered risk of childhood obesity. Objectives: We aimed to examine the effectiveness of food service staff training on meals and menu quality across NA ECEs. Methods: Food service staff from 9 participating ECE programs attended a 3-h training focused on Child and Adult Care Food Program (CACFP) best practices, and received a tailored, best-practice menu, and healthy recipes. Meals and menus prepared across 1 wk were examined per CACFP serving size assumptions at baseline, 4 mos, 6 mos, and 12 mos for all 9 programs. Healthy Eating Index (HEI), CACFP requirements and best practices achievement, and food substitutions quality (classified into superior, equivalent, and inferior based on the nutritional quality) were calculated. A repeated measures ANOVA model was used to determine the differences across time points. Results: The total meal HEI score increased significantly from baseline to 4 mos (71.1 ± 2.1; 78.6 ± 5.0; P = 0.004), but did not differ from baseline to 12 mos. Menu CACFP requirements and best practices achievement did not differ across time points, although achievement with CACFP requirements was already high at baseline. Superior nutrition quality substitutions declined from baseline to 6 mos (32.4 ± 8.9; 19.5 ± 10.9; P = 0.007); however, it did not differ from baseline to 12 mos. Equivalent and inferior quality substitutions did not differ across time points. Conclusions: Implementing a best-practice menu with healthy recipes showed immediate improvements in meal quality. Although the change did not sustain, this study showed evidence of an opportunity to educate and train food service staff. Robust efforts are needed for improving both meals and menus.This trial was registered ClinicalTrials.gov as NCT03251950 (https://clinicaltrials.gov/ct2/show/NCT03251950?cond=food+resource+equity&draw=2&rank=1).

Conceptualizing Indigenous strengths-based health and wellness research using group concept mapping.

BACKGROUND: In recent years public health research has shifted to more strengths or asset-based approaches to health research but there is little understanding of what this concept means to Indigenous researchers. Therefore our purpose was to define an Indigenous strengths-based approach to health and well-being research. METHODS: Using Group Concept Mapping, Indigenous health researchers (N = 27) participated in three-phases. Phase 1: Participants provided 218 unique responses to the focus prompt "Indigenous Strengths-Based Health and Wellness Research…" Redundancies and irrelevant statements were removed using content analysis, resulting in a final set of 94 statements. Phase 2: Participants sorted statements into groupings and named these groupings. Participants rated each statement based on importance using a 4-point scale. Hierarchical cluster analysis was used to create clusters based on how statements were grouped by participants. Phase 3: Two virtual meetings were held to share and invite researchers to collaboratively interpret results. RESULTS: A six-cluster map representing the meaning of Indigenous strengths-based health and wellness research was created. Results of mean rating analysis showed all six clusters were rated on average as moderately important. CONCLUSIONS: The definition of Indigenous strengths-based health research, created through collaboration with leading AI/AN health researchers, centers Indigenous knowledges and cultures while shifting the research narrative from one of illness to one of flourishing and relationality. This framework offers actionable steps to researchers, public health practitioners, funders, and institutions to promote relational, strengths-based research that has the potential to promote Indigenous health and wellness at individual, family, community, and population levels.

"I don't remember any of us having diabetes or cancer": How historical oppression undermines indigenous foodways, health, and wellness.

Past and present structures of settler colonial historical oppression aimed to erase and replace Indigenous peoples have profoundly disrupted U.S. Indigenous foodways. The purpose of this article is to use the Indigenous Framework of Historical Oppression, Resilience, and Transcendence (FHORT) to understand U.S. Indigenous peoples' experiences and perceptions of how (a) foodways have changed within the context of settler colonial historical oppression and (b) these changes have affected wellness and cultures of Indigenous peoples. Critical ethnographic analysis focused on data from 31 interviews with participants from a rural Southeast reservation and a Northwest urban context. Results revealed participants' descriptions of changing foodways situated in a system of historical oppression, with themes including (a) historical oppression and changing values and foodway practices; (b) settler colonial governmental programs interrupting foodways through commodities and rations; and (c) changing foodway practices: from homegrown and homemade to fast food and premade. Participants described the aftermath of settler colonial governmental policies and programs undermined foodways, connectedness, cultural knowledge, family and interpersonal relationships, ceremonies, and outdoor activities-all of which promote health and wellness. To redress historical oppression, including settler colonial governmental policies, decolonized decision-making, foodways, and Indigenous food sovereignty are recommended as approaches to inform policy and programming that affirms Indigenous values and worldviews.

Impact of a Farm-to-School Nutrition and Gardening Intervention for Native American Families from the FRESH Study: A Randomized Wait-List Controlled Trial.

Establishing healthy eating habits during childhood is critical to prevent chronic diseases that develop in adulthood. Tribally owned Early Childhood and Education (ECE) programs signify fundamental influence in childhood obesity disparities. A strategy to improve diet is the use of school gardens; however, few studies have used rigorous methods to assess diet and health outcomes. The purpose of this manuscript is to describe results from the six-month Food Resource Equity for Sustainable Health (FRESH) study among Native American families. We aimed to recruit 176 families of children attending Osage Nation ECE programs in four communities. Two communities received the intervention and two served as wait-list controls. Outcomes included change in dietary intake, body mass index, health status, systolic blood pressure (adults only), and food insecurity in children and parents. There were 193 children (n = 106 intervention; n = 87 control) and 170 adults (n = 93 intervention; n = 77 control) enrolled. Vegetable intake significantly increased in intervention children compared to controls for squash (p = 0.0007) and beans (p = 0.0002). Willingness to try scores increased for beans in intervention children (p = 0.049) and tomatoes in both groups (p = 0.01). FRESH is the first study to implement a farm-to-school intervention in rural, tribally owned ECEs. Future interventions that target healthy dietary intake among children should incorporate a comprehensive parent component in order to support healthy eating for all household members.

Impacts of COVID-19 on a Food Security Study with the Baltimore Native Community.

Urban American Indian/Alaska Native peoples experience disproportionate levels of food insecurity when compared to the general US population. Through a collaborative research partnership between Native American Lifelines of Baltimore, an Urban Indian Health Program, and a Johns Hopkins Bloomberg School of Public Health student-led research team, food security was identified as a priority issue. A sequential explanatory mixed methods study was planned to explore food security and food sovereignty in the Baltimore Native community prior to the COVID-19 pandemic. Due to the local impact of COVID-19, a community-based participatory research approach guided the community-academic team to revise the original study and increase understanding of how the pandemic impacted food security in the community. This article highlights the lessons learned and strengths of using a community-based participatory approach to guide adaptations made due to COVID-19 to this research study. By utilizing a co-learning approach and emphasizing flexibility, we were able to collaboratively collect meaningful data to drive future community solutions to food insecurity while building an evidence base for policy changes to better support urban Native food security.

Holding no-one back: The Nutrition Equity Framework in theory and practice.

Equity remains poorly conceptualised in current nutrition frameworks and policy approaches. We draw on existing literatures to present a novel Nutrition Equity Framework (NEF) that can be used to identify priorities for nutrition research and action. The framework illustrates how social and political processes structure the food, health and care environments most important to nutrition. Central to the framework are processes of unfairness, injustice and exclusion as the engine of nutrition inequity across place, time and generations, ultimately influencing both nutritional status and people's space to act. The NEF illustrates conceptually how action on the socio-political determinants of nutrition is the most fundamental and sustainable way of improving nutrition equity for everyone everywhere, through 'equity-sensitive nutrition'. Efforts must ensure, in the words of the Sustainable Development Goals, that not only is "no one left behind" but also that the inequities and injustices we describe do not hold anyone back from realising their right to healthy diets and good nutrition.
