In rural Native American communities, access to healthy foods is limited and diet-related disparities are significant. Tribally owned and operated convenience stores, small food stores that sell ready-to-eat foods and snacks primarily high in fat and sugar, serve as the primary and, in some areas, the only food stores. The Tribal Health and Resilience in Vulnerable Environments or “THRIVE” study, implemented between 2013 and 2018, is the first healthy retail intervention study implemented in tribally owned and operated convenience stores. THRIVE aims to increase vegetable and fruit intake among Native Americans living within the Chickasaw and Choctaw Nation of Oklahoma. The study comprises three phases: 1) formative research assessing tribal community food environments and associated health outcomes; 2) intervention development to assess convenience stores and tailor healthy retail product, pricing, promotion, and placement strategies; and 3) intervention implementation and evaluation. In this paper we share the participatory research process employed by our tribal-university partnership to develop this healthy retail intervention within the unique contexts of tribal convenience stores. We summarize our methods to engage tribal leaders across diverse health, government, and commerce sectors and adapt and localize intervention strategies that test the ability of tribal nations to increase fruit and vegetable purchasing and consumption among tribal members. Study processes will assist in developing a literature base for policy and environmental strategies that intervene broadly to improve Native community food environments and eliminate diet-related disparities among Native Americans.
Objectives. To assess a healthy retail intervention in Tribal convenience stores in Oklahoma. Methods. We adapted healthy retail strategies to the context of 8 Tribally owned stores. We assessed individual- and store-level outcomes in a cluster-controlled intervention trial (April 2016–June 2017). We measured fruit and vegetable intake, store environment perceptions, and purchases before and after the intervention among a cohort of 1637 Native American shoppers. We used mixed-effects linear regression to estimate pre- to postintervention changes in and between groups. Results. We followed 74% of participants (n = 1204) 9 to 12 months. Intervention and control participants perceived healthier stores after intervention. Higher shopping frequency was related to purchases of fruits, vegetables, and healthy items. Conclusions. Intervention exposure was associated with healthy purchasing but not fruit and vegetable intake. Research is needed to further assess impacts of environmental interventions on intake. Public Health Implications. As the first healthy retail intervention in Tribally owned stores, our results contribute evidence for environmental and policy interventions to address obesity in Tribal Nations. Multicomponent interventions, led by Tribal leaders from diverse sectors, are needed to create healthy environments and sustainable improvements in Native American health.
Objective To examine barriers to farmer’s market (FM) use by Supplemental Nutrition Assistance Program (SNAP) consumers receiving TANF. Design Focus groups. Setting An urban community in Oklahoma. Participants SNAP beneficiaries receiving TANF (n = 64, across 8 focus groups). Phenomenon of Interest Perceptions about FM foods and barriers to FM use. Analysis Transcript-based content analysis using the five dimensions of access framework. Results Few participants ate fresh produce regularly and most appreciated the convenience of shopping at a supermarket. FMs were not perceived as available or accommodating to shopping needs and affordability and acceptability concerns were expressed. Few were aware of FMs that accepted SNAP. Emerging themes suggested residential segregation and cultural barriers to FM use. Conclusions and Implications FM managers, community nutritionists, and researchers should develop interventions that correct common misperceptions about FM products, minimize access barriers, and increase awareness of SNAP payment options. Residential segregation and cultural barriers may play a role in FM use and should be explored further.
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.
