ABSTRACT
Objective To characterize the built nutritional environ-
ment in terms of types and number of food stores, avail-
ability, and cost of selected food items in a rural area.
Design A cross-sectional survey of food stores conducted
in 2004.
Subjects/setting We selected a rural county (population
91,582; 1,106 square miles). Food stores identified from a
database were mapped and presence, location, and store
type verified by ground-truthing. Stores were surveyed
for availability and cost of selected foods.
Main outcome measures Price and availability of a limited
number of staple foods representing the main food
groups.
Statistical analyses performed Availability comparisons used
least square means models and price comparisons used t
tests.
Results Of 77 stores identified, 16% were supermarkets,
10% grocery stores, and 74% convenience stores. There
were seven stores per 100 square miles and eight stores
per 10,000 residents. Availability of more healthful foods
was substantially higher at supermarkets and grocery
stores. For instance, low-fat/nonfat milk, apples, high-
fiber bread, eggs, and smoked turkey were available in
75% to 100% of supermarkets and groceries and at 4% to
29% of convenience stores. Foods that were available at
both supermarkets and convenience stores tended to be
substantially more expensive at convenience stores. The
healthful version of a food was typically more expensive
than the less healthful version.
Conclusions In this rural environment, stores offering
more healthful and lower-cost food selections were out-
numbered by convenience stores offering lower availabil-
ity of more healthful foods. Our findings underscore the
challenges of shopping for healthful and inexpensive
foods in rural areas.

T
he newly revised Dietary Guidelines for Americans
encourage healthful eating patterns and making
“wiser food choices.” For instance, a daily intake of 4
1
/2 cups of fruits and vegetables is recommended, and at
least half of the grain intake should come from whole-
grain foods (1). While dietary behavior has traditionally
been considered a function of individual choice, the eco-
logic perspective questions to what extent the nutritional
environment may facilitate or present barriers to health-
promoting individual behaviors (2).
The importance of the neighborhood environment for
health behaviors and health status is increasingly being
recognized (3-6). Disadvantaged neighborhoods, charac-
terized by overcrowding, lower social class, high percent
male unemployment, or households without cars, have
been shown to be associated with a variety of poor health
behaviors (7). While extensive research efforts are under-
way assessing how physical activity levels are impacted
by physical environment (8), comparatively little atten-
tion has been paid to the nutritional environment and its
influence on dietary behaviors and health outcomes.
The absence of supermarkets and the availability of
fast-food restaurants in a neighborhood has been related
to a reduced likelihood of consuming sufficient amounts of
fruits and vegetables (9,10). As the distance to a super-
market increases, a lower quality of dietary intake was
observed in lower-income pregnant women (11). In addi-
tion, the availability and display of health-promoting
foods seems to impact food intake (12).
While the vast majority of research in this area has
been conducted in urban or suburban settings, very
little is known about the nutritional environment in
rural areas. In the United States, 20% of the population
are rural residents (13). Rural areas are not only in-
herently sparsely populated and characterized by large
distances, but also by high levels of poverty, low housing
values, and low educational attainment of the resident
population. These characteristics can be associated with
lower geographic purchasing power, which can affect
business decisions about the location and types of food
stores and service places.
The purpose of this study was to characterize the types
and numbers of food stores and the availability and cost
of certain food items in a rural South Carolina county.
