This article describes a method of collecting and analyzing itemized grocery receipts for use in epidemiological studies. As part of a larger study of children's food acquisition and exercise habits related to cardiovascular disease, a sample of 50 families was asked to keep itemized grocery receipts for a 2-week period. To control for bias as a result of differences in food consumption and food acquisition, mothers were asked to log meals eaten away from home, food used from home production, and gifts of foods. Items on the receipts were coded according to food groups and whether they represented child-prompted purchases. The items were expressed in terms of the percentage of the food dollar each category represented. Data from the survey were compared with data collected in national surveys. The method was found to be relatively non-intrusive, easily carried out, and eliminated many of the problems associated with non-response, respondent burden, and recall characteristic of other food account methods. It is suggested as a feasible way of characterizing the family food environment in epidemiological studies. |
