Evidence for validity of five secondary data sources for enumerating retail food outlets in seven American Indian communities in North Carolina.

ABSTRACT:

Background

Most studies on the local food environment have used secondary sources to describe the food environment, such as government food registries or commercial listings (e.g., Reference USA).
