Abstract: The Navajo
Nation (NN) is the largest federally recognized tribe in the U.S. More than half of
Navajo residents live below the poverty line, 42% are unemployed, and one-third lack
plumbing and electricity. In addition, the Navajo people have some of the highest rates
of childhood obesity and food insecurity reported for a U.S. population. To reverse
these public health challenges, ... read morethe food environment must provide opportunities for
healthy eating at affordable prices. The food environment challenges identified in
urban, non-Native communities are structurally different from those faced in NN, so
there is a specific need to develop approaches appropriate to local conditions.
Convenience stores are the food outlets closest to 70% of Navajo communities, yet these
small stores vary in their availability of healthy options. Little is known about the
challenges and possible facilitators to supplying fruits and vegetables (F&V) to the
most remote regions in NN. The research objectives addressed were to 1) determine
F&V availability at all small stores in communities without grocery stores in NN, 2)
document customer perspectives on barriers to and facilitators of purchasing F&V at
these stores and, 3) understand store owner and manager views on stocking F&V. In
Aim 1, we used a modified Nutrition Environment Measures Survey (NEMS) in stores to
document all fresh, frozen and canned F&V at the 71 small stores in Navajo Nation
communities without grocery stores. We also compared the fresh F&V offerings
available at independently operated stores and regional and national chains. We found
that nine stores had no fresh fruits and twelve stores had no fresh vegetables
available. The overall median number of canned, fresh, and frozen F&V types offered
across all stores were nine, eight and three, respectively. There were more fresh fruit
and vegetable offerings at independently owned stores compared to regional or national
chain stores (p < 0.05). Aim 2 explored perspectives on food availability and
shopping preferences of 72 customers outside of 9 small stores in remote NN. Four
individuals (5.6%) purchased some F&V at the small store the day s/he was
interviewed and 32% had purchased some in the previous week. Most participants (64%)
shopped primarily at super center stores outside of their communities, yet about half
shopped at the small store at least twice per week. This suggests that the small stores
are important spaces to encourage healthful food purchasing. Shoppers would be more
inclined to purchase F&V if a greater variety were available at affordable prices.
For Aim 3, interviews with six owners and 16 managers of 22 small stores in NN revealed
that management would like to offer more fresh F&V. However, barriers exist, such as
perceived low demand, limited F&V offerings from distributors and for some managers,
minimal authority over product selection. Participants were interested in purchasing
products from local farmers however few relationships exist and there was concern with
food safety requirements. These findings document that increasing availability and
purchasing of F&V in remote NN is complex and must address both supply and demand
challenges. There are opportunities for increased dialogue among customers and
management to encourage augmentation of product offerings. There is also need to explore
creative sourcing, such as pooled purchasing among multiple locations, which could help
stores increase variety while decreasing cost to customers. Given current product
selection and varying levels of decision making autonomy, it will be necessary to pursue
different strategies when looking to partner with independently owned stores compared to
those that are part of regional or national chains. Study results will inform local
programmatic and advocacy efforts to increase healthy food access in remote
NN.
