Measuring Food Security among American Indian and Alaska Native Adults: Validity Evidence Supports the Use of the US Department of Agriculture Module.

BACKGROUND: Inequities in access, availability, and affordability of nutritious foods produced by settler colonialism contribute to high rates of food insecurity among American Indian and Alaska Native (AI/AN) households. Efforts to understand the influences of food security programming among AI/AN individuals in the United States are constrained by the absence of validity evidence for food security assessments for this population. OBJECTIVE: This study assessed whether AI/AN adult responses on the Food Security Survey Module provide an accurate assessment of food security prevalence, especially when compared with other racial and ethnic groups. DESIGN: A correlational design with the cross-sectional 2019 National Health Interview Survey was used to address the research objective. PARTICIPANTS AND SETTING: The 2019 National Health Interview Survey contains a sample (N = 30,052) representative of the resident civilian noninstitutionalized population. MAIN OUTCOME MEASURES: The primary outcome was food security, as characterized by the 10-item US Department of Agriculture Adult Food Security Survey Module. The module evaluates whether insufficient finances result in perceived food shortages and a reduction in the quantity and/or quality of food intake during the prior 30 days. STATISTICAL ANALYSES PERFORMED: Data were analyzed by racial and ethnic subsamples to assess scale dimensionality (confirmatory factor analysis), Item Response Theory item analysis, differential item functioning, and external validity (χ2 tests). RESULTS: Results supported the use of the 10-item module for racial and ethnic groups. However, differential item functioning effect sizes exceeded criteria for the Asian, AI/AN, and Hispanic respondents when compared with White respondents. Food security was not significantly related to all expected correlates in the AI/AN subsample. CONCLUSIONS: Compelling evidence is presented for validity of the FSSM scores in determining food security status of AI/AN adults. Qualitative inquiry that explores how culture influences the way food security is conceptualized and experienced is warranted.

Development and Implementation of a Hybrid Online and In-Person Food Sovereignty and Nutrition Education Curriculum for Native American Parents: The FRESH Study.

The Food Resource Equity and Sustainability for Health ("FRESH") study is an Indigenous-led intervention to increase vegetable and fruit intake among Native American children. As part of this study, we developed a hybrid (online and in-person) food sovereignty and nutrition education curriculum for the parents of these children. This 16-week curriculum was developed to promote household- and community-level healthy eating and food sovereignty practices to parents of preschool-aged children residing in Osage Nation, Oklahoma. A total of 81 parent/caregivers participated in the curriculum component of the FRESH study, with a median age of 34 years (range: 23-54 years). Most study participants were female (88.9%) and less than half (45.7%) had an annual household income of more than US$50,000. Most were married or had a significant other (76.5%) and worked full-time (65.4%). The median total number of children in the home <18 years of age was three (range: 1-8). Participation among the 94 parents was 56% during the first week and was 12% in the final week. Having some college or technical training (vs. having a college degree) and having an annual household income of US$20,000-US$50,000 (vs. more than US$50,000) were associated with fewer sessions attended (p = 0.004 and 0.02, respectively) Being married (vs. not) was associated with higher attendance (p < .0001). Participation in a hybrid food sovereignty and nutrition education curriculum for parents was generally low, but income, education, and marital status were associated with curriculum participation. Our research adds to the literature by describing the development and implementation of this curriculum and recommendations for future research incorporating Indigenous approaches to health.

Design and Methods of a Participatory Healthy Eating Intervention for Indigenous Children: The FRESH Study.

Objective: To increase vegetable and fruit intake, reduce body mass index (BMI), and improve parental blood pressure among American Indian families. Design: Randomized, wait-list controlled trial testing a multi-level (environmental, community, family, and individual) multi-component intervention with data collection at baseline and 6 months post-intervention. Setting: Tribally owned and operated Early Childhood Education (ECE) programs in the Osage Nation in Oklahoma. Participants: American Indian families (at least one adult and one child in a ECE program). A sample size of 168 per group will provide power to detect differences in fruit and vegetable intake. Intervention: The 6-month intervention consisted of a (1) ECE-based nutrition and gardening curriculum; (2) nutrition education and food sovereignty curriculum for adults; and (3) ECE program menu modifications. Main Outcome Measures: The primary outcome is increase in fruit and vegetable intake, assessed with a 24-h recall for adults and plate weight assessments for children. Secondary outcomes included objective measures of BMI among adults and children and blood pressure among adults.

Food Insecurity among American Indian and Alaska Native People: A Scoping Review to Inform Future Research and Policy Needs.

Food insecurity, defined as insufficient access to nutritious foods, is a social determinant of health that may underpin health disparities in the US. American Indian and Alaska Native (AI/AN) individuals experience many health inequities that may be related to food insecurity, but no systematic analyses of the existing evidence have been published. Thus, the objective of this scoping review was to assess the literature on food insecurity among AI/AN individuals and communities, with a focus on the prevalence of food insecurity and its relations to sociodemographic, nutrition, and health characteristics. Systematic search and data extraction processes were used. Searches were conducted on PubMed as well as peer-reviewed journal and government websites. Of 3174 identified references, 34 publications describing 30 studies with predominantly AI/AN sample populations were included in the final narrative synthesis. Twenty-two studies (73%) were cross-sectional and the remaining 8 (27%) described interventions. The weighted average prevalence of food insecurity across the studies was 45.7%, although estimates varied from 16% to 80%. Most studies used some version of the USDA Food Security Survey Modules, although evidence supporting its validity in AI/AN respondents is limited. Based on the review, recommendations for future research were derived, which include fundamental validity testing, better representation of AI/AN individuals in federal or local food security reports, and consideration of cultural contexts when selecting methodological approaches. Advances in AI/AN food insecurity research could yield tangible benefits to ongoing initiatives aimed at increasing access to traditional foods, improving food environments on reservations and homelands, and supporting food sovereignty.

Associations of Binge Drinking With Vascular Brain Injury and Atrophy in Older American Indians: The Strong Heart Study.

Objectives: American Indians (AIs) generally consume less alcohol than the US general population; however, the prevalence of alcohol use disorder is higher. This is the first large cohort study to examine binge drinking as a risk factor for vascular brain injury (VBI). Methods: We used linear and Poisson regression to examine the association of self-reported binge drinking with VBI, measured via magnetic resonance imaging (MRI), in 817 older AIs who participated in the Strong Heart and Cerebrovascular Disease and Its Consequences in American Indians studies. Results: Any binge drinking at multiple time-points was associated with increased sulcal (ß = 0.360, 95% CI [0.079, 0.641]) and ventricle dilatation (ß = 0.512, 95% CI [0.174, 0.850]) compared to no binge drinking. Discussion: These observed associations are consistent with previous findings. Identifying how binge drinking may contribute to VBI in older AIs may suggest modifiable health behaviors for neurological risk reduction and disease prevention.

A Nutrition Environment Measure to Assess Tribal Convenience Stores: The THRIVE Study.

In rural American Indian (AI) communities, where supermarkets are rare, tribally owned and operated convenience stores are an important food source. Food environment measures for these settings are needed to understand and address the significant diet-related disparities among AIs. Through a tribal-university partnership that included tribal health and commerce representatives from two Native Nations in rural southeastern Oklahoma, we developed the Nutrition Environment Measures Survey for Tribal Convenience Stores (NEMS-TCS) to inform the development and evaluation of a healthy food retail intervention. The NEMS-TCS assessed four scored domains of the rural convenience store food environment-food availability, pricing, quality, and placement-and included 11 food categories that emphasized ready-to-eat food items. Trained raters administered the NEMS-TCS using a sample of 18 rural convenience stores (primarily ranging between 2,400 and 3,600 square feet). We assessed interrater reliability with kappa statistics for dichotomized variables and intraclass correlation coefficients (ICC) for continuous variables. NEMS-TCS demonstrated high inter-rater reliability for all food categories (>85% agreement), subscores (ICC = 0.73-1.00), and the total score (ICC = 0.99). The NEMS-TCS responds to recent calls for reliable measures for rural food environments and may be valuable for studying food environments of large convenience stores in other Native Nations as well as other rural settings.

Prevention Research with Indigenous Communities to Expedite Dissemination and Implementation Efforts.

Effectively translating evidence-based interventions into clinic and community settings is an increasing priority for health researchers. The successful dissemination and implementation (D&I) of interventions found efficacious ensures that major health funders such as the National Institutes of Health can demonstrate a return on investment in biomedical and behavioral research and that all populations receive maximum benefit from scientific discoveries. However, the products of research efficacy trials, the evidence-based interventions, are rarely designed with D&I in mind, rendering these interventions fundamentally misaligned with real-world settings. Further, while some evidence-based interventions have been successfully adapted for implementation in indigenous communities, few such examples have been published. Literature regarding the adoption and implementation of evidence-based interventions in indigenous communities is scarce, and the feasibility of scaling up successful interventions is poorly understood, potentially widening health disparities. The Intervention Research to Improve Native American Health (IRINAH) partners are generating efficacy data on community-responsive and engaged interventions that are also designed to facilitate D&I efforts, reducing the time between research to practice to benefit indigenous communities, should these interventions prove effective. In this manuscript, we provide an overview and key challenges of D&I science with indigenous communities. We then use IRINAH case studies to highlight strategies that IRINAH partners are using to plan for the scale-up and implementation of the studies. We conclude with recommendations to inform the next phase of IRINAH research efforts.

Multilevel and Community-Level Interventions with Native Americans: Challenges and Opportunities.

Multilevel and community-level interventions that target the social determinants of health and ultimately health disparities are seldom conducted in Native American communities. To contextualize the importance of multilevel and community-level interventions, major contributors to and causes of health disparities in Native communities are highlighted. Among the many documented socioeconomic factors influencing health are poverty, low educational attainment, and lack of insurance. Well-recognized health disparities include obesity, diabetes, and hypertension. Selected challenges of implementing community-level and multilevel interventions in Native communities are summarized such as the shortage of high-quality population health data and validated measurement tools. To address the lack of multilevel and community-level interventions, the National Institutes of Health created the Intervention Research to Improve Native American Health (IRINAH) program which solicits proposals that develop, adapt, and test strategies to address these challenges and create interventions appropriate for Native populations. A discussion of the strategies that four of the IRINAH grantees are implementing underscores the importance of community-based participatory policy work, the development of new partnerships, and reconnection with cultural traditions. Based on the work of the nearly 20 IRINAH grantees, ameliorating the complex social determinants of health disparities among Native people will require (1) support for community-level and multilevel interventions that examine contemporary and historical factors that shape current conditions; (2) sustainability plans; (3) forefronting the most challenging issues; (4) financial resources and time to collaborate with tribal leaders; and (5) a solid evidence base.

Food Insecurity and Chronic Diseases Among American Indians in Rural Oklahoma: The THRIVE Study.

OBJECTIVES: To examine food insecurity and cardiovascular disease-related health outcomes among American Indians (AIs) in rural Oklahoma. METHODS: We surveyed a cross-sectional sample of 513 AI adults to assess food insecurity domains (i.e., food quality and quantity) and obesity, diabetes, and hypertension. RESULTS: Among AIs surveyed, 56% reported inadequate food quantity and 62% reported inadequate food quality. The unadjusted prevalence of diabetes (28.4% vs 18.4%), obesity (60.0% vs 48.3%), and hypertension (54.1% vs 41.6%) was higher among participants with inadequate food quantity than among those with adequate food quantity. These associations did not reach statistical significance after adjustment for age, gender, study site, education, and income. The unadjusted prevalence of obesity (60.7% vs 45.8%), diabetes (27.3% vs 18.8%), and hypertension (52.5% vs 42.5%) was higher among those with inadequate food quality than among those with adequate food quality, even after adjustment for age, gender, study site, education, and income. CONCLUSIONS: Tribal, federal, and state policymakers, as well as businesses and nonprofit organizations, must collaboratively take aggressive action to address food insecurity and its underlying causes, including improving tribal food environments, reducing barriers to healthy foods, and increasing living wages.

Gambling with our health: smoke-free policy would not reduce tribal casino patronage.

BACKGROUND: Tribal sovereignty exempts tribal casinos from statewide smoking bans. PURPOSE: To conduct a tribally-led assessment to identify the characteristics of casino patrons at Lake of the Torches Resort Casino in Lac du Flambeau WI and their preferences for a smoke-free casino. METHODS: A survey was administered from April to August 2011 to a stratified random sample of 957 members of the casino players club to assess their preferences for a smoke-free casino. These members were categorized into three groups: those who reported being likely to (1) visit more; (2) visit less; or (3) visit the same if the casino prohibited smoking. They were characterized by age, education, sex, race/ethnicity, annual income, players club level, and reasons for visiting the casino. Statistical analyses were conducted on weighted data in October to December 2011. Weighted logistic regression was calculated to control for potential confounding of patron characteristics. RESULTS: Of the 957 surveyed patrons, 520 (54%) patrons were likely to visit more; 173 (18%) patrons to visit less; and 264 (28%) patrons were indifferent to the smoke-free status. Patrons more likely to prefer a smoke-free casino tended to be white, elderly, middle class and above, and visit the casino restaurants. Patrons within the lower tiers of the players club, almost half of the players club members, also showed a higher preference for a smoke-free casino. CONCLUSIONS: This tribal casino would likely realize increased patronage associated with smoke-free status while also contributing to improved health for casino workers and patrons.

The implementation of a participatory manuscript development process with Native American tribal awardees as part of the CDC Communities Putting Prevention to Work initiative: challenges and opportunities.

OBJECTIVE: In 2009, the Centers for Disease Control and Prevention funded 50 communities, including three tribal awardees, to implement environmental approaches to address obesity and smoking through the Communities Putting Prevention to Work initiative. The tribes were among the selected awardees offered training support for analyzing, writing, and publishing their findings. This article describes the process of translating the workshops, guided by a participatory framework, for implementation with the tribes. METHODS: Nine participants from three tribes attended the workshops in Decatur, Georgia, in August and October of 2012: 1) a one-day pre-conference workshop focused on integrating both Indigenous and academic evaluation methods; 2) a 4 day data analysis workshop; and 3) a 5 day scientific writing workshop. Participants were provided with technical assistance following the workshops. RESULTS: Participants viewed the workshops positively and have continued to develop their manuscripts. To date one tribal awardee has submitted their manuscript for publication. CONCLUSION: The participatory manuscript development process described here is the first of its kind outlining a pathway for tribal community health practitioners to translate and publish their work. Further development of this process could increase the number of community-developed manuscripts, thereby advancing the field of translational intervention science and leading to improved health equity.
