Abstract (Summary)

Objectives/Introduction. Grocery stores offer unique platforms for nutrition interventions. Nutrition professionals typically advise menu-planning using grocery stores sales circulars to help stretch family food budgets. But a paucity of research surrounds the characteristics of foods advertised in Washington (WA) State groceries’ online circulars. The purpose of this cross-sectional study is to investigate foods advertised by major WA grocers in order to establish degree of accordance with the dietary guidelines for Americans (DGA) 2010, Healthy People 2020, and MyPlate recommendations.

Methods. An online grocery circular assessment model (OGCAM) was developed based on the following MyPlate food groups: dairy, fruits, vegetables, protein and whole grains. Scores were assigned in accordance with DGA 2010 and Healthy People 2020 recommendations and Healthy Eating Index where higher number indicate better nutrition quality. For six weeks, scores were examined from foods advertised by seven major groceries’ across WA State. The OGCAM scores were computed for each MyPlate-derived food group. ANOVA analysis was performed to determine significant differences among advertised food items in the analyzed stores.

Results. 865 advertised foods were analyzed from seven major WA State grocery stores circulars. The average OGCAM score was normally distributed (n = 42; SD = 1.45; p = 0.042). All stores showed weekly variation in terms of number of foods advertised (M=20.60, SD 6.69). The following Fresh/Processed OGCAM scores were calculated: Safeway = 450/278; Albertson = 403/348; QFC = 384/270; Fred Meyer = 218/250; Whole Foods = 368/485; Metropolitan Market = 342/445; and Haggen = 405/165. The average difference in OGCAM scores for advertised foods in all seven stores was not statistically significant (F(6,35) = 1.940, p = 0.102).

Conclusions. WA grocers advertised foods are in accordance with dietary recommendations. However, they must continue in promoting nutritious foods through circulars to maintain adherence to federal dietary guidelines.
