Shopper Purchasing Trends at Small Stores on the Navajo Nation since the Passage of the Healthy Dine Nation Act Tax: A Multi-Year Cross-sectional Survey.

ABSTRACT:

Background

In 2014, the Navajo Nation passed the Healthy Diné Nation Act (HDNA), which applies an additional 2% tax on unhealthy foods and beverages and a waiver of Navajo sales tax on healthy foods and beverages. However, the HDNA's impact on purchasing behavior has not been explored.

Objectives

We assessed beverage and produce purchasing trends among shoppers at small Navajo stores between 2017 and 2019, shopper characteristics associated with buying water, and whether HDNA awareness was associated with purchasing behaviors.

Methods

A total of 332 shoppers at 34 stores in 2017 and 274 shoppers at 44 stores in 2019 were surveyed to assess HDNA awareness and same-day purchasing of water, sugar-sweetened beverages (SSBs), fruits, and vegetables. Hypotheses were tested using chi-square analyses and multivariate analysis.

Results

Water purchasing among respondents increased significantly from 2017 to 2019 (24.4% to 32.8%; P = 0.03). Shoppers in 2019 were 1.5 times more likely to purchase water compared with 2017 (adjusted P = 0.01). There was a trend toward reduced SSB purchasing (85.8% in 2017, 80.3% in 2019, P = 0.068), while produce purchasing remained unchanged over time, at approximately 17%. Shoppers were more likely to buy water if they relied on that store for the majority of their groceries (P = 0.006) and if they did not have their own transportation to get to the store (P = 0.004). Most shoppers (56.6%) were aware of the HDNA; of these, 35.6% attributed healthier habits to the HDNA, most commonly buying more healthy drinks (49.2%), fewer unhealthy drinks (37.7%), more healthy snacks (31.1%), and fewer unhealthy snacks (26.2%).

Conclusions

Shopper habits at small stores located on the Navajo Nation have shifted towards healthier purchasing from 2017 to 2019. Shoppers who were aware of the HDNA reported purchasing more healthy and fewer unhealthy food and drinks as a result of this legislation.

Project description:BackgroundAmerican Indians and Alaska Natives experience diet-related health disparities compared with non-Hispanic whites. Navajo Nation's colonial history and remote setting present unique challenges for healthy food access.ObjectiveThis study aims to understand the impact of the Healthy Navajo Stores Initiative (HNSI) on fruit and vegetable purchasing on Navajo Nation.MethodsWe conducted a cross-sectional survey of 692 customers shopping at 28 convenience stores, trading posts, and grocery stores on Navajo Nation. Individual- and household-level sociodemographic data and food purchasing behaviors were collected. Descriptive and bivariate analyses for customers' individual- and household-level characteristics were conducted using chi-squared tests. The impact of individual-, household-, and store-level factors on fruit and vegetable purchasing was assessed using multiple logistic regression modeling.ResultsStore participation in the HNSI was significantly associated with customers' purchase of produce. Customers experienced 150% higher odds of purchasing produce if they shopped in participating stores, compared with nonparticipating stores (P < 0.001). Store type was strongly associated with customers' purchase of fruits or vegetables. Customers shopping at a grocery store had 520% higher odds of purchasing produce than did customers shopping at convenience stores (P < 0.001). Customers shopping at trading posts had 120% higher odds of purchasing fruits or vegetables than did customers shopping at convenience stores (P = 0.001).ConclusionsOur findings reveal increased produce purchasing at stores participating in the HNSI. Customers were significantly more likely to purchase fruits or vegetables in stores enrolled in a healthy store intervention than in nonenrolled stores, after controlling for quantity of produce stocked and store type. Customers shopping in grocery stores and trading posts were significantly more likely to purchase produce than customers shopping in convenience stores. These findings have implications for food access in rural tribal communities.

Project description:ContextTo promote the health of the Navajo people, the Navajo Nation passed the Healthy Diné Nation Act (HDNA) in 2014. The HDNA included a 2% tax on "minimal-to-no-nutritional-value" foods and waived 5% sales tax on healthy foods, the first such policy in the United States and any sovereign Tribal nation. Uniquely aligned with Tribal government structures, revenue was directly allocated to 110 small local government entities (Chapters) for self-determined wellness projects.ObjectiveTo characterize HDNA-funded wellness projects, test for variation in project type, and funding amount over time by region and community size.DesignLongitudinal study assessing funded wellness projects from tax inception through 2019.SettingThe Navajo Nation.ParticipantsOne hundred ten Navajo Nation Chapters receiving funding for self-determined wellness projects.Outcome measuresThe categories and specific types of wellness projects and funding over 4 years by region and community size.ResultsOf revenue collected in 2015-2018, more than 99.1% was disbursed through 2019 ($4.6 million, $13 385 annually per community) across 1315 wellness projects (12 per community). The built recreational environment category received 38.6% of funds, equipment/supplies 16.5%, instruction 15.7%, food and water initiatives 14.0%, and social events 10.2%. Most common specific projects were walking trails ($648 470), exercise equipment ($585 675), food for events ($288 879), playgrounds ($287 471), and greenhouses ($275 554). Only the proportion allocated to instruction changed significantly over time (increased 2% annually, P = .02). Smaller communities (population <1000) allocated significantly higher proportions to traditional, agricultural, and intergenerational projects and less to the built environment.ConclusionsThrough 2019, more than 99% of HDNA revenue was successfully disbursed to 110 rural, Tribal communities. Communities chose projects related to promoting the built recreational environment, agriculture, and fitness/nutrition education, with smaller communities emphasizing cultural and intergenerational projects. These findings can inform other indigenous nations considering similar policies and funding distributions.

Project description:On April 8, 2020, the Navajo Nation issued an administrative order limiting business operations. Facing high coronavirus disease 2019 (COVID-19) rates and limited food infrastructure, a survey was conducted among Navajo Nation store managers to assess: (1) COVID-19 adaptations; (2) challenges; (3) changes in customer volume and purchasing; and (4) suggestions for additional support. Purposive sampling identified 29 stores in Navajo communities. Representatives from 20 stores (19 store managers/owners, 1 other; 7 grocery, and 13 convenience/other stores) were interviewed by phone or in-person to reach saturation (new information threshold < 5%). Responses were coded using frequencies and inductive thematic analysis. All 20 stores implemented COVID-19 guidelines (Centers for Disease Control and Prevention [CDC]/Navajo Nation) and most received orientation/support from local chapters, community organizations, or health centers. Stores implemented staff policies (50%, handwashing, vaccinations, protective personal equipment (PPE), sick leave, temperature checks), environmental changes (50%, hand sanitizer, checkout dividers), customer protocols (40%, limit customers, mask requirements, closed restrooms), and deep cleaning (40%). Most stores (65%) reported challenges including stress/anxiety, changing guidelines, supply chain and customer compliance; 30% reported infection or loss of staff. Weekday customer volume was slightly higher vs. pre-COVID, but weekend lower. Stores reported consistent or more healthy food purchases (50%), more nonfood essentials (20%), or shelf-stable foods (10%). Desired support included further orientation (30%), leadership support (20%), overtime/time to learn guidelines (20%), and signage/handouts (15%). Despite a high COVID-19 burden and limited food store infrastructure, Navajo Nation stores adapted by implementing staff, environmental and customer policies. Local support, staffing, and small store offerings were key factors in healthy food access.
