Methods
Data for the current study were collected as part of a larger study of individual, family, and environmental influences on adolescent obesity in primarily rural and small town geographic areas of Northern New England. The study, titled “Environmental and Family Influences on Adolescent Overweight,” was approved by the Committee for the Protection of Human Subjects at Dartmouth College.
Results and Discussion
The sampling area covered 1,237.6 square miles, encompassing 7% of the total combined land area in New Hampshire and Vermont. Towns were well-distributed by population size: rural, n=11; small town, n=7; mid-sized town, n=8; and urban, n=6. Nine hundred and forty-three food outlets were identified through public directory listings and 960 through field observations. After accounting for overlap, this provided a sample of 1,340 unique food outlets. Twenty-seven percent were food markets and 73%
Conclusions
This study represents one of the largest samples of food outlets to date validated through field verification methods, identifying nearly 1,000 outlets in the primarily low-population sampling area. The sample included four distinct population patterns within a relatively small geographic area, and assessed eight types of food outlets, providing a comprehensive description of the regional food environment. The efficacy of using public directories to identify community food outlets in

Piloting or pretesting of primary data collection instruments was explicitly mentioned in five studies14,18,19,31,34 (26%). Re-canvassing the study area to look for retail food outlets identified via secondary data sources that did not match the outlets identified via primary data was noted in three studies13,14,20 (16%).
